Question 41
In Azure, what is “vertical scaling”?
a) Increasing the number of virtual machine instances
b) Adding more compute resources (CPU, memory) to an existing virtual machine
c) Distributing workloads across multiple regions
d) Reducing the storage capacity of a service
Correct Answer: b) Adding more compute resources (CPU, memory) to an existing virtual machine
Explanation: Vertical scaling involves adding more resources (CPU, memory) to a single virtual machine to increase its capacity.
Question 42
What is the purpose of the “Gremlin” API in Cosmos DB?
a) To perform graph-based queries and traversal
b) To store and retrieve binary data
c) To provide encryption for sensitive data
d) To manage user access
Correct Answer: a) To perform graph-based queries and traversal
Explanation: The Gremlin API in Cosmos DB is used for graph databases, enabling graph traversal and queries over nodes and edges.
Question 43
What is the purpose of “resource locks” in Azure?
a) To encrypt data stored in a resource
b) To prevent accidental deletion or modification of critical resources
c) To ensure resource availability during scaling operations
d) To manage network access to resources
Correct Answer: b) To prevent accidental deletion or modification of critical resources
Explanation: Resource locks prevent accidental deletion or modification of critical Azure resources, ensuring they remain protected.
Question 44
Which Azure service provides two-way communication between clients and servers for real-time messaging?
a) Azure Event Grid
b) Azure SignalR Service
c) Azure Service Bus
d) Azure Blob Storage
Correct Answer: b) Azure SignalR Service
Explanation: Azure SignalR Service enables real-time, two-way communication between clients and servers, often used in chat applications and live updates.
Question 45
What is the purpose of Azure “App Configuration”?
a) To store and manage application secrets
b) To manage app-specific configuration settings in a centralized location
c) To scale applications automatically
d) To configure virtual machines for hosting apps
Correct Answer: b) To manage app-specific configuration settings in a centralized location
Explanation: Azure App Configuration allows developers to store and manage application settings in a centralized repository, simplifying app configuration across environments.
Question 46
Which Azure service allows you to build event-driven architectures with triggers and outputs?
a) Azure Event Grid
b) Azure Functions
c) Azure Logic Apps
d) Azure Service Bus
Correct Answer: b) Azure Functions
Explanation: Azure Functions allows developers to create event-driven architectures using various triggers and bindings to connect to different services.
Question 47
What is the role of the “input binding” in an Azure Function?
a) To provide event-driven execution of the function
b) To allow the function to read data from external sources
c) To store output data
d) To manage the function’s state
Correct Answer: b) To allow the function to read data from external sources
Explanation: Input bindings in Azure Functions are used to connect the function to external data sources, enabling the function to read data during execution.
Question 48
What is the main advantage of using the Azure Cache for Redis Premium tier?
a) Higher security
b) Lower latency and larger memory capacity
c) Lower cost compared to other tiers
d) Automatic backup of cached data
Correct Answer: b) Lower latency and larger memory capacity
Explanation: The Premium tier of Azure Cache for Redis offers larger memory capacity and lower latency for high-performance workloads.
Question 49
In Cosmos DB, what is an “eventual consistency” model?
a) Writes are always visible immediately
b) Reads may return stale data, but replicas eventually converge to the same state
c) Reads and writes are guaranteed to be consistent
d) The data is partitioned across regions
Correct Answer: b) Reads may return stale data, but replicas eventually converge to the same state
Explanation: Eventual consistency provides the highest performance by allowing reads to return stale data, but all replicas eventually converge to the same state.
Question 50
What is the benefit of using Azure Blob Storage “soft delete”?
a) To encrypt blobs during storage
b) To recover deleted blobs within a retention period
c) To replicate blobs across regions
d) To compress blobs for storage
Correct Answer: b) To recover deleted blobs within a retention period
Explanation: Soft delete in Azure Blob Storage allows for the recovery of accidentally deleted blobs within a specified retention period.
