a) Batch processing
b) Message Sessions
c) Dead-letter Queue
d) Duplicate Detection
Correct Answer: c) Dead-letter Queue
Explanation: The Dead-letter Queue stores messages that cannot be processed, allowing for review and reprocessing at a later time.
Question 26
What role does a “Product” play in Azure API Management?
a) It defines access control for APIs
b) It is used to bundle APIs and apply policies
c) It stores usage metrics
d) It manages virtual machines
Correct Answer: b) It is used to bundle APIs and apply policies
Explanation: In Azure API Management, Products are used to group APIs and apply policies, such as rate limiting or authentication requirements.
Question 27

a) Shared Access Signature (SAS)
b) Account key
c) Access policy
d) Secret key
Correct Answer: b) Account key
Explanation: The Account key provides full control over all resources in an Azure Storage account, allowing for read, write, and delete operations.
Question 28
In Cosmos DB, what consistency level provides the fastest read performance but no guarantee of data ordering?
a) Eventual
b) Consistent Prefix
c) Session
d) Strong
Correct Answer: a) Eventual
Explanation: The Eventual consistency level provides the fastest read performance but does not guarantee the order in which data is read.
Question 29
Which feature in Azure Cosmos DB provides a log of changes for inserts and updates?
a) TTL
b) Partitioning
c) Change Feed
d) Consistency Levels
Correct Answer: c) Change Feed
Explanation: The Change Feed in Cosmos DB provides a log of changes, capturing inserts and updates for further processing.
Question 30

Question 35
What is the purpose of the Azure Service Bus “Partitioned Queue”?
a) To guarantee FIFO message processing
b) To divide a queue into multiple partitions for better scalability
c) To store large binary files
d) To provide a dead-letter queue
Correct Answer: b) To divide a queue into multiple partitions for better scalability
Explanation: A Partitioned Queue in Azure Service Bus splits the queue into multiple partitions, enhancing scalability and fault tolerance.
Question 36
In Cosmos DB, what is a “hot partition”?
a) A partition with high replication
b) A partition that stores only write-heavy data
c) A partition that receives most requests and reaches throughput limits
