Correct Answer: c) To provide key-value pairs for additional information about the blob
Explanation: Metadata headers are used to store key-value pairs that provide additional information about a blob, such as custom tags or attributes.
Question 28
In Cosmos DB, what is the purpose of the Change Feed?
a) To track database schema changes
b) To capture and log all reads from the database
c) To monitor data changes and trigger events or workflows
d) To manage access control for database users
Correct Answer: c) To monitor data changes and trigger events or workflows
Explanation: The Change Feed in Cosmos DB provides a log of changes to the data, enabling you to trigger workflows or synchronize changes with other systems.
Question 29
What is the purpose of Azure Active Directory B2C?
a) To provide secure access to internal applications
b) To manage IoT devices in Azure
c) To enable customer identity and access management
d) To monitor application performance
Correct Answer: c) To enable customer identity and access management
Explanation: Azure Active Directory B2C is designed for customer-facing applications, providing identity and access management for external users.
Question 30
Which Cosmos DB consistency level guarantees that reads will return the most recent committed write?
a) Strong
b) Bounded Staleness
c) Eventual
d) Consistent Prefix
Correct Answer: a) Strong
Explanation: The Strong consistency level in Cosmos DB ensures that all reads return the most recent committed write, providing linearizability.
Question 31
What is the purpose of “role-based access control” (RBAC) in Azure?
a) To manage VM scaling
b) To control access to Azure resources based on roles assigned to users
c) To encrypt data stored in Azure Storage
d) To manage user profiles in Azure AD
Correct Answer: b) To control access to Azure resources based on roles assigned to users
Explanation: RBAC is used to control who can access Azure resources and what actions they can perform, based on assigned roles.
Question 32
Which Azure service would you use to manage infrastructure as code for deploying resources?
a) Azure Monitor
b) Azure Service Bus
c) Azure Resource Manager (ARM)
d) Azure Blob Storage
Correct Answer: c) Azure Resource Manager (ARM)
Explanation: ARM templates allow you to manage infrastructure as code, automating the deployment and configuration of Azure resources.
Question 33
What is the purpose of “tags” in Azure resources?
a) To encrypt data
b) To classify resources for billing and management
c) To enable autoscaling
d) To enforce security policies
Correct Answer: b) To classify resources for billing and management
Explanation: Tags are key-value pairs used to classify and organize resources, making it easier to track usage and costs.
Question 34
In Azure Blob Storage, what is the role of the “hot” access tier?
a) For infrequently accessed data
b) For data that requires fast access and frequent reads/writes
c) For archiving data
d) For read-only workloads
Correct Answer: b) For data that requires fast access and frequent reads/writes
Explanation: The hot access tier is optimized for data that needs frequent access with minimal latency, offering faster performance.
Question 35
n Azure API Management, what is a “product”?
a) A collection of APIs that can be published and managed together
b) A virtual machine template
c) A service for monitoring API usage
d) A database for storing API keys
Correct Answer: a) A collection of APIs that can be published and managed together
Explanation: In Azure API Management, a product is a collection of APIs that can be published, subscribed to, and managed as a group.
Question 36
What is the purpose of “advanced filtering” in Azure Event Grid?
a) To encrypt messages
b) To select events based on specific criteria, such as values in the event data
c) To route messages to multiple handlers
d) To manage storage access
Correct Answer: b) To select events based on specific criteria, such as values in the event data
Explanation: Advanced filtering in Azure Event Grid allows event handlers to receive only relevant events by filtering based on event data.
Question 37
In Azure Cosmos DB, what is the function of a “lease container” in the Change Feed processor?
