Domain 1 — Develop containerized solutions on Azure
1.1 Container fundamentals
|
Concept |
Short description |
Exam trick |
|
Container |
Runs an application with its required dependencies in an
isolated environment. |
Same image can run in development, testing, and
production. |
|
Container image |
Packaged, versioned blueprint used to create containers. |
Image is the package; container is the running instance. |
|
Dockerfile |
Instructions for building an image. |
Build instructions are not the same as a running
container. |
|
Container registry |
Stores and distributes images. |
ACR stores images; it does not run your application. |
|
Repository and tag |
Organize images and identify versions. |
latest is just a tag; it is not guaranteed to mean the
newest or safest image. |
|
Image digest |
Content-based identifier for a specific image artifact. |
Prefer digest-based references when immutable image
identification matters. |
|
ACR Tasks |
Builds or automates image workflows in Azure Container
Registry. |
Useful when builds should run in Azure without managing
your own build machine. |
|
Registry authentication |
Grants a workload access to pull or push images. |
For pulling private ACR images, check the correct identity
and registry permissions. |
1.2 Azure Container Apps
|
Concept |
Short description |
Exam trick |
|
Container Apps environment |
Shared boundary for related Container Apps and their
networking/observability configuration. |
Think of it as the environment hosting related apps. |
|
Container App |
Managed platform for containerized APIs, web apps, and
workers. |
Choose it when you want containers without managing
Kubernetes directly. |
|
Revision |
Immutable snapshot of an app configuration and template. |
Configuration change or new image can create a new
revision. |
|
Replica |
Running instance of a revision. |
Revision = version; replica = running copy. |
|
Single revision mode |
Traffic transitions between revisions as the new revision
becomes ready. |
Best when you don't need to operate multiple revisions
concurrently. |
|
Multiple revision mode |
Lets you keep revisions active and control traffic between
them. |
Use for canary testing, gradual rollout, and rollback
strategies. |
|
Traffic splitting |
Distributes requests across active revisions. |
Example: 90% old version, 10% new version. |
|
Ingress |
Controls how requests reach the application. |
External = public entry point; internal = private entry
point within the supported network scope. |
|
Target port |
Port on which the application listens inside its
container. |
A mismatch can make a deployed app unreachable. |
|
Environment variables |
Provide runtime configuration to the application. |
Different environments can use the same image with
different settings. |
|
Secrets |
Store sensitive configuration for app consumption. |
Do not hardcode secrets into source code or Docker images. |
|
Managed identity |
Lets a workload authenticate to supported Azure services
without storing its own credentials. |
Identity provides authentication; permissions still need
to be granted. |
|
KEDA scaling |
Event-driven scaling based on supported external or
internal signals. |
Queue backlog → KEDA-based worker scaling. |
|
HTTP scaling |
Scales based on incoming HTTP workload and configured
rules. |
Web/API traffic → HTTP scaling may be appropriate. |
|
Scale to zero |
Allows replicas to reduce to zero when configured
conditions permit. |
Saves resources, but a new request/event may incur startup
latency. |
|
Container Apps Jobs |
Runs finite tasks to completion. |
Scheduled report or one-time batch → Job; continuously
serving requests → app. |
|
Dapr |
Adds distributed-application capabilities through APIs and
components. |
Service invocation, pub/sub, state management, bindings;
it is not a replacement for all Azure services. |
|
Monitoring and logs |
Help inspect runtime behavior, failures, and events. |
A running container does not automatically mean the
application is healthy. |
Container Apps: high-value exam traps
- New
version with controlled rollout: revisions and traffic splitting.
- Variable
queue workload: KEDA scaling.
- Run
a task at a specific time: scheduled Container Apps Job.
- Public
frontend with private backend: configure ingress appropriately for each
app.
- Application
listens on port 8080 but ingress targets 80: check target-port
configuration and the actual listening port.
- Secret
retrieval returns 403: check identity permissions and networking, not just
whether the identity exists.
- New
revision fails: inspect the new revision's logs, configuration, image,
port, and dependencies.
1.3 Azure App Service and AKS
|
Concept |
Short description |
Exam trick |
|
App Service |
Managed platform for web apps and APIs, including
supported custom containers. |
Conventional web app/API with minimal infrastructure
management → consider App Service. |
|
App Service configuration |
Runtime settings, environment variables, and deployment
configuration. |
Keep environment-specific settings outside the image. |
|
AKS |
Azure Kubernetes Service for Kubernetes-based
orchestration. |
Choose when Kubernetes control, advanced orchestration, or
ecosystem compatibility is required. |
|
Cluster / node |
Cluster is the Kubernetes environment; nodes provide
compute capacity. |
If Pods cannot schedule, check available node capacity and
resource requests. |
|
Pod |
Smallest Kubernetes deployable unit; contains one or more
containers. |
Troubleshoot the Pod before assuming the entire cluster is
broken. |
|
Deployment |
Manages desired Pod replicas and rolling updates. |
Wrong replica count or rollout state → inspect Deployment. |
|
Service |
Provides stable networking to selected Pods. |
Pods change; Service provides a stable endpoint. |
|
Ingress |
Routes incoming HTTP/HTTPS traffic to Services. |
App runs but URL is unreachable → inspect Ingress,
Service, selectors, and ports. |
|
ConfigMap |
Stores non-sensitive Kubernetes configuration. |
Ordinary configuration → ConfigMap; sensitive values
require appropriate secret handling. |
|
Kubernetes Secret |
Holds sensitive configuration such as credentials. |
Do not assume stored Secrets are automatically encrypted
or securely accessible in every setup. |
|
ImagePullBackOff |
Kubernetes repeatedly fails to pull an image. |
Check image name/tag, registry authentication, ACR
permissions, and network. |
|
CrashLoopBackOff |
Container repeatedly starts and crashes. |
Check application logs, startup command, configuration,
and dependencies. |
|
Pending Pod |
Pod cannot yet be scheduled or started. |
Check resource requests, node capacity, constraints, and
scheduling events. |
|
Liveness probe |
Checks whether the container should be restarted. |
Persistent liveness failure can trigger restart. |
|
Readiness probe |
Checks whether the Pod should receive normal traffic. |
Failed readiness removes the Pod from ready Service
endpoints; it does not normally restart it. |
|
Startup probe |
Allows slow-starting applications time to initialize. |
Use to protect slow startup from premature liveness
failures. |
|
CPU/memory requests |
Declare resources used for scheduling decisions. |
Requests influence placement and capacity calculations. |
|
CPU/memory limits |
Restrict resource usage. |
CPU can be throttled; memory-limit exceedance can lead to
OOM termination. |
|
HPA |
Horizontal Pod Autoscaler changes Pod replica count. |
More application instances → HPA. |
|
Cluster Autoscaler |
Adjusts the number of cluster nodes when its conditions
are met. |
More compute nodes → Cluster Autoscaler. |
Choose the right hosting service
- ACR:
store container images.
- App
Service: managed web app/API hosting.
- Container
Apps: managed containers, event scaling, revisions, and jobs.
- AKS:
Kubernetes orchestration and advanced control.
Domain 2 — Develop AI solutions using Azure data
management services
This domain has the largest exam weighting: 25–30%. Focus
especially on selecting the correct database, partitioning, vector search,
consistency, and caching.
2.1 Azure Cosmos DB for NoSQL
|
Concept |
Short description |
Exam trick |
|
Account → Database → Container → Item |
Logical hierarchy for NoSQL data. |
Container holds JSON-like items. |
|
Partition key |
Determines how items are distributed across logical
partitions. |
Choose based on access patterns and data distribution;
avoid hot partitions. |
|
High-cardinality key |
A key with many distinct values. |
Often helps distribute load, but does not guarantee good
partitioning. |
|
Request Units (RUs) |
Measure the resources consumed by database operations. |
Expensive query or write → examine RU consumption. |
|
Provisioned throughput |
Reserves throughput capacity, commonly measured in RU/s. |
Sustained demand beyond available throughput can cause
throttling. |
|
HTTP 429 |
Request throttling. |
Check RU/s, query efficiency, and retry behavior; do not
assume the database is unavailable. |
|
Point read |
Retrieves one item using its ID and partition key. |
Known ID + partition key → point read is often the
efficient choice. |
|
Cross-partition query |
Query that needs to search across partitions. |
Missing partition-key filter can increase cost. |
|
Indexing policy |
Controls which JSON paths are indexed. |
Indexes can improve query performance but add write and
storage overhead. |
|
Consistency levels |
Control how recent and consistent reads are across
replicas. |
Select the weakest consistency level that satisfies the
application's requirements. |
|
Session consistency |
Provides session-level read-your-writes guarantees. |
Useful when a user should see their own recent changes. |
|
Change Feed |
Exposes changes to items for downstream processing. |
React to data changes → Change Feed; retrieve current
matching data → query. |
|
Change Feed Processor |
Coordinates change processing across workers, commonly
using a lease container. |
For distributed processing, consider checkpointing,
leases, and idempotent handlers. |
|
Vector search |
Retrieves semantically similar items using embeddings. |
RAG retrieval → embeddings + vector similarity + relevant
context. |
|
Metadata filtering |
Restricts retrieval by attributes such as category or
tenant. |
Use filters when semantic similarity alone is
insufficient. |
|
Hybrid search |
Combines vector similarity with keyword-based retrieval. |
Useful when both semantic meaning and exact terms matter. |
Cosmos DB consistency: memory trick
Think from strongest to weakest consistency guarantees:
- Strong:
strongest consistency guarantee.
- Bounded
staleness: reads may lag within configured bounds.
- Session:
useful session-level guarantees, including read-your-writes.
- Consistent
prefix: updates are observed in order, without guaranteeing the latest
write.
- Eventual:
replicas converge when updates stop, without a guarantee of immediate
freshness.
Exam trap: Session consistency is not the same as globally
strong consistency.
Exam trick: RAG supplies relevant external context to an
LLM; it does not automatically retrain or change the model's weights.
2.2 Azure Database for PostgreSQL + pgvector
|
Concept |
Short description |
Exam trick |
|
PostgreSQL |
Managed relational database service. |
Structured entities, transactions, joins, and relational
constraints → PostgreSQL. |
|
Table / row / column |
Relational data organization. |
Use SQL for relational queries. |
|
Npgsql |
Common .NET data provider for PostgreSQL. |
.NET application connecting to PostgreSQL → Npgsql is a
key name to recognize. |
|
Connection pooling |
Reuses database connections rather than creating one for
every operation. |
Helps connection overhead; it does not increase database
CPU capacity. |
|
pgvector |
PostgreSQL extension for storing and searching vector
embeddings. |
Relational data + semantic similarity search → PostgreSQL
+ pgvector is a strong fit. |
|
Embedding dimensions |
Number of values in a vector. |
Query and stored vectors must have compatible dimensions. |
|
Cosine similarity |
Compares vector direction/orientation. |
Often used for semantic similarity; understand whether the
implementation reports similarity or distance. |
|
Euclidean distance |
Measures straight-line distance between vectors. |
Lower distance generally means closer vectors under this
metric. |
|
Inner product |
Measures a vector dot product. |
Interpretation depends on vector normalization and the
search implementation. |
|
ANN search |
Approximate nearest-neighbor retrieval. |
Can improve search speed at the cost of some retrieval
accuracy. |
|
Metadata filtering |
Restricts vector results to eligible records. |
Important for tenant boundaries, categories, and business
constraints. |
Exam trap: PostgreSQL + pgvector is not a separate Azure
database product. pgvector adds vector capabilities to PostgreSQL.
2.3 Azure Managed Redis
|
Concept |
Short description |
Exam trick |
|
In-memory cache |
Stores frequently accessed data for low-latency retrieval. |
Reduce repeated database reads and response time →
consider Redis. |
|
Cache hit |
Requested value exists in cache. |
Return the cached value when valid. |
|
Cache miss |
Requested value is absent. |
Fetch from the source database and populate the cache. |
|
Cache-aside |
Application checks the cache first, then reads and updates
it on a miss. |
The application controls the cache flow. |
|
TTL |
Time to live; controls when cached data expires. |
Helps limit how long old data remains cached. |
|
Cache invalidation |
Removes or refreshes stale cached values. |
Data changes in the source → consider invalidation or
refresh. |
|
Redis vector search |
Supported Redis capabilities can index and search vectors. |
Redis may support vector retrieval, but choose based on
persistence, query, and application needs. |
|
Source of truth |
The authoritative data store. |
Do not treat an ordinary cache as the authoritative
database by default. |
Domain 3 — Connect to and consume Azure services
The central exam skill is distinguishing commands, events,
and execution.
3.1 Azure Service Bus
|
Concept |
Short description |
Exam trick |
|
Message broker |
Reliably mediates asynchronous communication between
applications. |
Decouple a producer from a worker. |
|
Queue |
Holds messages for consumers to process. |
A work item is typically processed by one competing
consumer, subject to delivery and settlement semantics. |
|
Topic |
Routes published messages to subscriptions. |
Several independent systems need the same message → topic
+ subscriptions. |
|
Subscription |
Independent message stream associated with a topic. |
Each eligible subscription can receive its own copy. |
|
Message settlement |
Marks a message completed, abandoned, or otherwise
handled. |
Complete after successful processing, not before. |
|
Retry / redelivery |
Makes failed or unsettled messages available for another
attempt. |
Design for duplicate delivery; processing should be
idempotent where needed. |
|
Dead-letter queue (DLQ) |
Holds messages that cannot be processed normally. |
Repeated failures or poison messages → inspect DLQ and
failure reason. |
|
Duplicate detection |
Helps filter duplicate sends within configured conditions. |
Do not assume it makes every business operation
exactly-once. |
|
Sessions |
Group and order related messages under session semantics. |
Ordered processing of related messages → consider
sessions. |
3.2 Azure Event Grid
|
Concept |
Short description |
Exam trick |
|
Event |
Notification that something happened. |
“A blob was uploaded” is an event. |
|
Event source |
Resource or application that emits events. |
Identify where the event originates. |
|
Event subscription |
Specifies which events go to which handler and under what
filters. |
Route selected event types to the correct consumer. |
|
Event handler |
Receives and processes events. |
Azure Functions and supported webhooks are common
handlers. |
|
Event filtering |
Limits delivery based on event type, subject, or supported
properties. |
Reduce unnecessary event processing. |
|
Custom topic |
Supports events emitted by your own application or domain. |
Use when publishing custom business events. |
|
Retry and dead-lettering |
Handle delivery failures according to configured behavior. |
Event delivery is not proof that business processing
completed successfully. |
3.3 Azure Functions
|
Concept |
Short description |
Exam trick |
|
Function |
A unit of code executed in response to a trigger. |
Use for event-driven or serverless tasks. |
|
Function App |
Hosting and configuration boundary for functions. |
A Function App can contain multiple functions. |
|
Trigger |
Starts a function execution. |
HTTP request, timer, Service Bus message, or Event Grid
event. |
|
Input binding |
Supplies data to a function. |
Retrieves or exposes input using a supported binding. |
|
Output binding |
Sends data to a supported destination. |
Can simplify integration; direct SDK code is also
possible. |
|
Durable Functions |
Adds stateful orchestration patterns for supported
function workloads. |
Multi-step workflows, coordination, and durable waiting →
consider Durable Functions. |
|
Managed identity |
Authenticates the function to supported Azure services
without embedded credentials. |
Identity alone does not grant the required permissions. |
Exam traps
- Multiple
independent consumers need copies of events → Event Grid subscriptions or
Service Bus topic subscriptions, depending on the delivery and processing
requirements.
- Reliable
asynchronous business work → Service Bus is often the better fit.
- Run
code on a timer → Azure Functions timer trigger or an appropriate
scheduled job.
- Event
notification does not itself guarantee that downstream business work has
completed.
- A
queue consumer may receive a message more than once; make critical
operations safe to retry.
Domain 4 — Secure, monitor, and troubleshoot Azure
solutions
This domain combines security, configuration, telemetry,
monitoring, and root-cause troubleshooting. Exam questions often describe a
failure and ask for the most appropriate next step.
4.1 Azure Key Vault
|
Concept |
Short description |
Exam trick |
|
Secrets |
Stores passwords, API keys, tokens, and connection
strings. |
Sensitive application value → Key Vault. |
|
Keys |
Cryptographic keys used for encryption, signing, and
related operations. |
Encryption/signing requirement → keys. |
|
Certificates |
Manages supported certificates and related lifecycle
operations. |
TLS certificate requirement → certificates. |
|
Managed identity |
Provides workload identity without embedding credentials. |
Avoid storing service-principal passwords in code. |
|
Authorization |
Controls what an identity may do. |
Identity exists ≠ permission to read secrets. |
|
Secret versioning |
Maintains versions of secret values. |
New version may not automatically refresh a running app. |
|
Rotation |
Replaces credentials or cryptographic material under a
planned process. |
Update dependent systems and refresh consumers; changing
Key Vault alone may be insufficient. |
|
Access troubleshooting |
Checks identity, role or access policy, network access,
and secret status. |
A 403 is a clue to investigate authorization or network
restrictions. |
Remember the flow: application → authenticate using identity
→ Key Vault authorizes access → application retrieves the secret.
4.2 Azure App Configuration
|
Concept |
Short description |
Exam trick |
|
Centralized configuration |
Stores shared, generally non-sensitive application
settings. |
Manage settings across environments without rebuilding the
image. |
|
Labels |
Distinguish configuration values, often by environment or
version. |
A label does not automatically detect the environment or
enforce security. |
|
Feature flags |
Control whether functionality is enabled. |
Enable or disable a feature without a full redeployment
when the app supports refreshing the flag. |
|
Dynamic refresh |
Updates configuration consumed by running applications. |
Refresh is not necessarily instantaneous across all
instances. |
|
Key Vault references |
Allow configuration to reference a secret stored in Key
Vault. |
The secret value belongs in Key Vault, not as a plain-text
App Configuration setting. |
Key Vault vs App Configuration
- Password
or API key → Key Vault.
- Feature
flag or non-sensitive application setting → App Configuration.
- Runtime
environment-specific value → environment configuration, often supplied
through the hosting platform.
- Credential-free
Azure service authentication → Managed Identity.
4.3 Identity, RBAC, and network security
|
Concept |
Short description |
Exam trick |
|
Authentication |
Establishes who or what is making a request. |
“Who are you?” |
|
Authorization |
Determines what the identity can access or do. |
“What are you allowed to do?” |
|
Azure RBAC |
Assigns roles to principals at defined scopes. |
Apply least privilege at the appropriate scope. |
|
Management-plane permissions |
Control resource management operations. |
Permission to manage a resource does not automatically
mean permission to read its data. |
|
Data-plane permissions |
Control access to service data. |
Reading Key Vault secrets requires the appropriate data
access permission. |
|
System-assigned identity |
Identity associated with one Azure resource's lifecycle. |
It is generally removed with its associated resource. |
|
User-assigned identity |
Separate identity resource that can be assigned to
supported workloads. |
Useful when identity lifecycle should be independent or
shared. |
|
Private Endpoint |
Provides private connectivity to a supported service. |
Private networking does not automatically grant
authorization. |
|
Network restrictions |
Control permitted network paths to a resource. |
Correct identity and role may still fail if network access
is blocked. |
|
Least privilege |
Grants only the access needed for the task. |
Avoid broad roles when a narrower role works. |
Troubleshooting status codes: quick clues
|
Symptom |
First things to investigate |
|
401 Unauthorized |
Missing, invalid, or expired credentials/token;
authentication configuration. |
|
403 Forbidden |
Role or permission, wrong identity, access policy, or
network restrictions. |
|
Timeout |
DNS, routing, firewall, private endpoint configuration, or
service responsiveness. |
|
404 Not Found |
Wrong resource, endpoint, path, or resource state. |
|
Key Vault access denied |
Confirm the identity actually used by the workload, its
data permissions, and network access. |
These are diagnostic clues, not absolute rules: inspect the
service's detailed error and logs.
4.4 OpenTelemetry distributed tracing
|
Concept |
Short description |
Exam trick |
|
OpenTelemetry (OTel) |
Vendor-neutral framework for generating, collecting, and
exporting telemetry. |
OTel is not itself a monitoring dashboard or database. |
|
Trace |
Represents a request's journey through one or more
services. |
Follow one slow request end-to-end. |
|
Span |
Represents one operation within a trace. |
A database call or HTTP request can be a span. |
|
Trace ID |
Identifies the overall trace. |
Related spans in the same trace share the trace ID. |
|
Span ID |
Identifies an individual span. |
Different spans normally have different span IDs. |
|
Parent-child relationship |
Shows how operations relate within a trace. |
Helps identify which operation called a slow dependency. |
|
Context propagation |
Carries trace context between services. |
Disconnected traces across services → check propagation
and instrumentation. |
|
Attributes and events |
Add contextual metadata or timestamped events to spans. |
Useful for filtering and explaining a request's behavior. |
|
Automatic instrumentation |
Instruments supported libraries and frameworks with
limited code changes. |
Good starting point for common .NET HTTP and dependency
telemetry. |
|
Manual instrumentation |
Adds spans around custom application operations. |
Use for business steps that automatic instrumentation
cannot describe adequately. |
|
OpenTelemetry Collector |
Receives, processes, and exports telemetry when included
in the architecture. |
Useful for centralized processing and routing. |
|
Sampling |
Controls which traces are retained or processed. |
Missing traces may be due to sampling, not necessarily a
broken app. |
Trace vs logs vs metrics
- Trace:
What happened during this specific request?
- Log:
What event or error occurred?
- Metric:
How much CPU, latency, or error rate is observed over time?
4.5 Azure Monitor, Application Insights, and Log
Analytics
|
Concept |
Short description |
Exam trick |
|
Azure Monitor |
Broad Azure monitoring platform. |
Think platform for collecting, analyzing, and acting on
telemetry. |
|
Application Insights |
Application performance monitoring and application
telemetry. |
Investigate requests, dependencies, exceptions, and
application behavior. |
|
Log Analytics workspace |
Stores and queries supported log data using KQL. |
Run log queries here. |
|
Azure Monitor Metrics |
Numeric time-series measurements. |
CPU percentage, request count, or latency trends →
metrics. |
|
Alerts |
Evaluate conditions and trigger actions or notifications. |
Select the alert type based on the signal and condition. |
|
Metric alert |
Evaluates a metric condition. |
CPU above a threshold → metric alert. |
|
Log alert |
Evaluates a log query condition. |
More than 20 failed requests within a window → query-based
alert. |
|
Diagnostic settings |
Route supported resource logs and metrics to configured
destinations. |
Missing resource logs → verify diagnostic settings,
destination, permissions, and ingestion. |
|
Retention and ingestion |
Affect how long data is available and may affect cost. |
More telemetry is not always better; balance diagnostic
value and cost. |
4.6 Kusto Query Language (KQL)
KQL is used to query supported log tables. The exam may test
query reading, filtering, aggregation, and troubleshooting logic.
|
Operator / function |
Meaning |
Memory trick |
|
where |
Filters rows by a condition. |
Which records do I want? |
|
project |
Selects columns. |
Which fields do I want to see? |
|
extend |
Adds a calculated column. |
Create a derived value. |
|
summarize |
Aggregates or groups records. |
Count or calculate averages by category. |
|
count |
Counts rows. |
How many records? |
|
order by / sort by |
Sorts results. |
Newest or slowest first. |
|
top / take |
Limits the result set. |
Return fewer rows. |
|
join |
Combines related tabular results. |
Correlate data from multiple tables. |
|
ago() |
Calculates a time relative to the current time. |
ago(1h) means one hour ago. |
|
bin() |
Buckets values, often timestamps, into intervals. |
Trend errors or latency over time bins. |
KQL exam patterns
|
Requirement |
Think of |
|
Filter errors |
where |
|
Display only a few fields |
project |
|
Count errors by code |
summarize count() by ResultCode |
|
Find average duration by operation |
summarize avg(DurationMs) by Name |
|
Show latest failures |
order by TimeGenerated desc |
|
Group errors into five-minute intervals |
bin(TimeGenerated, 5m) |
|
Investigate a specific request across services |
Distributed trace and correlated telemetry |
|
Investigate CPU growth |
Metrics first; use logs and traces for supporting evidence |
