b) Azure Application Insights
c) Azure Service Bus
d) Azure Active Directory
Correct Answer: b) Azure Application Insights
Explanation: Azure Application Insights provides monitoring and diagnostic capabilities for applications to help improve performance and usability.
Question 06
What happens when a Cosmos DB partition exceeds its throughput capacity?
a) Requests are rejected with a 429 error
b) Requests are automatically rerouted to a different region
c) Data is automatically split into multiple partitions
d) The partition is archived
Correct Answer: a) Requests are rejected with a 429 error
Explanation: When a partition exceeds its throughput capacity, additional requests are throttled, resulting in a 429 "Too Many Requests" error.
Question 07
What is the default maximum retention period for logs in Azure Application Insights?
a) 7 days
b) 30 days
c) 90 days
d) 365 days
Correct Answer: b) 30 days
Explanation: By default, Application Insights retains logs for 30 days, after which they are automatically deleted.
Question 08
Which Azure service allows you to deploy and manage containerized applications without managing the underlying infrastructure?
a) Azure Kubernetes Service
b) Azure Container Instances
c) Azure Virtual Machines
d) Azure Service Bus
Correct Answer: b) Azure Container Instances
Explanation: Azure Container Instances provide a simple way to run containerized applications without managing the underlying infrastructure.
Question 09
What is the role of the “orchestrator function” in Durable Functions?
a) It executes individual tasks asynchronously
b) It defines the workflow and coordinates the execution of activity functions
c) It logs errors and tracks exceptions
d) It manages data synchronization between services
Correct Answer: b) It defines the workflow and coordinates the execution of activity functions
Explanation: The orchestrator function in Durable Functions coordinates the order of function execution and handles state management across tasks.
Question 10
What is the Azure service used to securely store tokens, passwords, certificates, and secrets?
a) Azure Active Directory
b) Azure Key Vault
c) Azure Storage Account
d) Azure Monitor
Correct Answer: b) Azure Key Vault
Explanation: Azure Key Vault is designed to securely store sensitive information like tokens, passwords, and certificates.
Question 11
What is the main purpose of Azure Event Grid?
a) To store unstructured data
b) To route and manage events between sources and event handlers
c) To monitor application performance
d) To provide messaging between microservices
Correct Answer: b) To route and manage events between sources and event handlers
Explanation: Azure Event Grid routes events from various sources to handlers like Azure Functions or Logic Apps.
Question 12
Which type of Azure Storage account provides the highest throughput for large file workloads?
a) Standard General-purpose v1
b) Standard General-purpose v2
c) Premium Block Blob Storage
d) Archive Storage
Correct Answer: c) Premium Block Blob Storage
Explanation: Premium Block Blob Storage offers the highest throughput for workloads involving large file transfers and frequent data access.
Question 13
What does the “standard deviation” measure in a dataset?
a) The average value
b) The dispersion or variability of data points from the mean
c) The frequency of each category
d) The total number of observations
Correct Answer: b) The dispersion or variability of data points from the mean
Explanation: Standard deviation quantifies how much individual data points deviate from the mean, indicating the degree of spread in the dataset.
Question 14
What is the purpose of a “lease” in Azure Blob Storage?
a) To ensure exclusive access to a blob for read and write operations
b) To track changes to a blob over time
c) To replicate blobs across regions
d) To compress blobs to save storage space
Correct Answer: a) To ensure exclusive access to a blob for read and write operations
Explanation: A lease ensures exclusive access to a blob, preventing other processes from modifying or deleting it during the lease period.
Question 15
Which feature in Azure Functions allows for durable, long-running workflows?
a) Output bindings
b) Orchestrator function
c) Event Grid
d) Input bindings
Correct Answer: b) Orchestrator function
Explanation: The orchestrator function in Durable Functions enables the creation of durable, long-running workflows by coordinating the execution of multiple activity functions.
Question 16
What is the benefit of using the “Session” consistency level in Cosmos DB?
a) It guarantees the fastest write operations
b) It ensures global availability with eventual consistency
c) It balances performance and consistency for user sessions
d) It guarantees strong consistency across regions
Correct Answer: c) It balances performance and consistency for user sessions
Explanation: Session consistency ensures that within a single session, reads always reflect the most recent writes, balancing performance and consistency.
Question 17
In Azure Key Vault, what is the “soft delete” feature?
