Question 24
Which property of a Cosmos DB container determines how data is divided among physical partitions?
a) Partition key
b) Container size
c) Consistency level
d) Indexing policy
Correct Answer: a) Partition key
Explanation: The partition key determines how the data is distributed across physical partitions, affecting performance and scalability.
Question 25
What is the purpose of the “event handler” in Azure Event Grid?
a) To generate events
b) To store event logs
c) To receive and process events
d) To filter event topics
Correct Answer: c) To receive and process events
Explanation: An event handler in Azure Event Grid receives events and processes them accordingly, such as triggering a function.
Question 26
Which tier of Azure Blob Storage is most appropriate for data that is infrequently accessed but still needs to be available quickly?
a) Hot tier
b) Cool tier
c) Archive tier
d) Premium tier
Correct Answer: b) Cool tier
Explanation: The Cool tier is designed for infrequently accessed data, balancing lower storage costs with moderate access times.
Question 27
What is the purpose of the Azure Monitor “Smart Detection” feature?
a) To monitor network performance
b) To predict future costs
c) To detect potential application performance issues
d) To check for security vulnerabilities
Correct Answer: c) To detect potential application performance issues
Explanation: Smart Detection in Azure Monitor identifies potential performance problems or anomalies in applications based on collected telemetry data.
Question 28
Which command would you use to copy a blob between two Azure storage accounts?
a) azcopy copy
b) az storage copy
c) blob move
d) azure blob copy
Correct Answer: a) azcopy copy
Explanation: The azcopy copy command allows for the transfer of blobs between different storage accounts using the AzCopy tool.
Question 29
What is the function of the “dependencies” property in an ARM template?
a) It lists the resources that must be deleted
b) It defines resources that must be created before others
c) It sets default values for resource creation
d) It specifies the location for resource deployment
Correct Answer: b) It defines resources that must be created before others
Explanation: The dependsOn property in ARM templates ensures that specific resources are deployed in the correct order by defining dependencies.
Question 30
What is the best way to provide external users limited access to a blob in Azure Storage?
a) Assign them a subscription
b) Provide a Shared Access Signature (SAS)
c) Create a new Azure AD account for them
d) Add them as a resource group owner
Correct Answer: b) Provide a Shared Access Signature (SAS)
Explanation: A Shared Access Signature (SAS) grants limited access to Azure resources such as blobs, allowing external users to interact with the resource without full access to the storage account.
Question 31
What should you do if a developer needs access to only a specific container in an Azure Storage account?
a) Provide the account access key
b) Assign the user to the Blob Storage owner role
c) Create a Shared Access Signature (SAS) for the container
d) Create a new storage account for the container
Correct Answer: c) Create a Shared Access Signature (SAS) for the container
Explanation: A Shared Access Signature (SAS) provides scoped, time-limited access to specific Azure resources like a storage container.
Question 32
What is a primary benefit of using Azure Cosmos DB’s “Bounded Staleness” consistency level?
a) It offers the highest performance for reads
b) It balances performance with consistency within a configured time window
c) It ensures that all reads return the latest version
d) It has the lowest latency for write operations
Correct Answer: b) It balances performance with consistency within a configured time window
Explanation: Bounded Staleness allows for a time window where reads might be slightly out of sync with writes, offering a balance between consistency and performance.
Question 33
In Cosmos DB, what is a physical partition?
a) A group of logical partitions
b) A single document storage unit
c) A container for partition keys
d) A server in a different region
Correct Answer: a) A group of logical partitions
Explanation: A physical partition in Cosmos DB contains one or more logical partitions and is physically stored on Azure servers.
Question 34
What is the role of the “Orchestrator” function in Azure Durable Functions?
a) It handles the deployment of function apps
b) It sequences and manages the execution of activity functions
c) It manages serverless API calls
d) It writes logs for function executions
Correct Answer: b) It sequences and manages the execution of activity functions
Explanation: The orchestrator function in Durable Functions defines workflows by managing the sequence and coordination of other functions.
Question 35
What is the default retention period for logs in Application Insights?
a) 7 days
b) 30 days
c) 90 days
d) 365 days
Correct Answer: b) 30 days
Explanation: Application Insights retains logs for 30 days by default, although this can be configured to store data for longer periods.
Question 36
Which service allows you to store application configuration settings centrally for multiple Azure applications?
a) Azure Key Vault
b) Azure App Service
c) Azure Storage
d) Azure App Configuration
Explanation: Azure App Configuration provides a centralized store for application configuration settings, allowing easy management across multiple Azure services.
Question 37
Which consistency level in Azure Cosmos DB provides the best trade-off between consistency and performance?
a) Eventual
b) Consistent Prefix
c) Session
d) Strong
Correct Answer: c) Session
Explanation: Session consistency offers a good balance between strong consistency and performance, particularly for scenarios involving multiple read/write operations in a user session.
Question 38
What is a primary advantage of using serverless compute in Azure Functions?
a) Unlimited execution time
b) Reduced costs as you only pay for executions
c) Access to full VMs for each function
d) Automatic access to GPUs
Correct Answer: b) Reduced costs as you only pay for executions

Which type of access control boundary is used to manage access at the subscription level in Azure?
a) Billing boundary
b) Resource group boundary
c) Access control boundary
d) Management boundary
Correct Answer: c) Access control boundary
Explanation: Access control boundaries in Azure are applied at the subscription level to manage permissions and access for resources.
