Test your knowledge of technical writing concepts with these practice questions. Each question includes detailed explanations to help you understand the correct answers.

Question 41: In Azure, what is "vertical scaling"?

Increasing the number of virtual machine instances

Adding more compute resources (CPU, memory) to an existing virtual machine

Distributing workloads across multiple regions

Reducing the storage capacity of a service

Question 42: What is the purpose of the "Gremlin" API in Cosmos DB?

To perform graph-based queries and traversal

To store and retrieve binary data

To provide encryption for sensitive data

To manage user access

Question 43: What is the purpose of "resource locks" in Azure?

To encrypt data stored in a resource

To prevent accidental deletion or modification of critical resources

To ensure resource availability during scaling operations

To manage network access to resources

Question 44: Which Azure service provides two-way communication between clients and servers for real-time messaging?

Azure Event Grid

Azure SignalR Service

Azure Service Bus

Azure Blob Storage

Question 45: What is the purpose of Azure "App Configuration"?

To store and manage application secrets

To manage app-specific configuration settings in a centralized location

To scale applications automatically

To configure virtual machines for hosting apps

Question 46: Which Azure service allows you to build event-driven architectures with triggers and outputs?

Azure Event Grid

Azure Functions

Azure Logic Apps

Azure Service Bus

Question 47: What is the role of the "input binding" in an Azure Function?

To provide event-driven execution of the function

To allow the function to read data from external sources

To store output data

To manage the function's state

Question 48: What is the main advantage of using the Azure Cache for Redis Premium tier?

Higher security

Lower latency and larger memory capacity

Lower cost compared to other tiers

Automatic backup of cached data

Question 49: In Cosmos DB, what is an "eventual consistency" model?

Writes are always visible immediately

Reads may return stale data, but replicas eventually converge to the same state

Reads and writes are guaranteed to be consistent

The data is partitioned across regions

Question 50: What is the benefit of using Azure Blob Storage "soft delete"?

To encrypt blobs during storage

To recover deleted blobs within a retention period

To replicate blobs across regions

To compress blobs for storage
