a) Hosting a high-traffic website
b) Storing long-term, infrequently accessed data
c) Storing real-time application logs
d) Short-term backup
Correct Answer: b) Storing long-term, infrequently accessed data
Explanation: Archive Storage is optimized for long-term storage of data that is rarely accessed, providing lower storage costs but higher retrieval times.
Question 05
What is the minimum duration for data to remain in the Cool tier of Azure Blob Storage?
a) 7 days
b) 30 days
c) 90 days
d) 180 days
Correct Answer: b) 30 days
Explanation: Data stored in the Cool tier must remain there for at least 30 days to optimize storage costs.
Question 06
In Azure Functions, what is an “output binding”?
a) A way to scale out functions automatically
b) A connection to a data destination that allows functions to write data
c) A configuration that links functions to triggers
d) A mechanism to handle errors in function execution
Correct Answer: b) A connection to a data destination that allows functions to write data
Explanation: Output bindings in Azure Functions provide a declarative way to write data to various services without manually coding connections.
Question 07
What is a key use case for Azure Blob Storage?
a) Storing relational database tables
b) Hosting an event-driven application
c) Storing unstructured data such as images and videos
d) Managing real-time messaging services
Correct Answer: c) Storing unstructured data such as images and videos
Explanation: Azure Blob Storage is ideal for storing large amounts of unstructured data like images, videos, and backups.
Question 08
. Which feature of Azure Key Vault provides automated access management to keys and secrets for Azure resources?
a) Managed Identity
b) API Keys
c) Custom Roles
d) Role-Based Access Control (RBAC)
Correct Answer: a) Managed Identity
Explanation: Managed Identity in Azure Key Vault allows Azure resources to access secrets and keys securely without needing credentials.
Question 09
How is horizontal scaling in Azure different from vertical scaling?
a) It adds more compute resources to a single VM
b) It reduces the number of VMs used
c) It increases the size of a VM’s CPU and memory
d) It adds or removes instances of an application
Correct Answer: d) It adds or removes instances of an application
Explanation: Horizontal scaling adds or removes instances of an application to handle changes in demand, while vertical scaling increases the resources of a single instance.
Question 10
. What is a CRON expression used for in Azure Functions?
a) To define a serverless architecture
b) To set a time-based schedule for function execution
c) To monitor system logs
d) To handle blob storage events
Correct Answer: b) To set a time-based schedule for function execution
Explanation: CRON expressions are used in Azure Functions to schedule events based on a specified time interval.
Question 11
In Azure Storage, what does the acronym “SAS” stand for?
a) Service Access Standard
b) Storage Access Script
c) Secure Account Service
d) Shared Access Signature
Correct Answer: d) Shared Access Signature
Explanation: A Shared Access Signature (SAS) provides secure, time-limited access to Azure Storage resources without exposing full credentials.
Question 12
What is the minimum throughput for an Azure Cosmos DB container?
a) 100 request units per second
b) 200 request units per second
c) 400 request units per second
d) 500 request units per second
Correct Answer: c) 400 request units per second
Explanation: Azure Cosmos DB containers require a minimum throughput of 400 request units per second (RUs).
Question 13
In Azure, what is the purpose of the “Lease Blob” operation?
a) To permanently lock a blob from being accessed
b) To acquire exclusive write and delete access to a blob
c) To read data from a blob more efficiently
d) To set permissions for public blob access
Correct Answer: b) To acquire exclusive write and delete access to a blob
Explanation: The "Lease Blob" operation in Azure provides exclusive access to write or delete a blob for a specified period.
Question 14
What is the Azure Function “Durable Client” responsible for?
a) Managing all input bindings
b) Defining a workflow sequence for a durable function
c) Starting and managing durable orchestrations
d) Handling blob storage triggers
Correct Answer: c) Starting and managing durable orchestrations
Explanation: The Durable Client in Azure Functions is responsible for starting and managing orchestrations and workflows in durable functions.
Question 15
Which consistency level in Cosmos DB ensures that reads are guaranteed to be consistent within a preconfigured lag?
a) Eventual
b) Bounded Staleness
c) Strong
d) Session
Correct Answer: b) Bounded Staleness
Explanation: Bounded Staleness guarantees reads to be consistent within a preconfigured lag, offering a balance between consistency and performance.
Question 16
What is the correct way to retrieve a secret from Azure Key Vault using its URL?
a) https://vault.azure.com/{key}
b) https://{vault-name}.vault.azure.net/{secret}/{version}
