Explanation

Azure Site Recovery is a disaster recovery service that helps replicate workloads and support recovery when a primary location becomes unavailable. It can help organizations maintain business continuity by orchestrating recovery of supported workloads in another Azure region or location. Site Recovery is focused on disaster recovery rather than routine backups. Azure Advisor provides recommendations, DNS manages name resolution, and Bastion provides secure administrative access to virtual machines. Site Recovery is therefore useful when an organization needs a planned recovery strategy for workloads affected by major outages or disasters.

Question 143

Which Azure storage redundancy option stores copies of data across multiple availability zones within a region?

  1. LRS
  2. GRS
  3. ZRS
  4. RA-GRS

Correct Answer: 3

Explanation

Zone-redundant storage, or ZRS, synchronously replicates data across multiple availability zones within a single Azure region. This provides resilience if one availability zone experiences an outage while keeping the data within the same region. Locally redundant storage, or LRS, maintains multiple copies within a single datacenter or physical location. Geo-redundant options replicate data to another region as well. ZRS is therefore a suitable choice when an organization needs protection against a zonal failure while maintaining regional data placement.

Question 144

Which Azure storage access tier is generally intended for data that is accessed frequently?

  1. Archive
  2. Cool
  3. Premium
  4. Hot

Correct Answer: 4

Explanation

The Hot access tier is designed for data that is accessed frequently. It is commonly used when applications regularly read or write stored data and need economical access costs for active workloads. The Cool tier is intended for data that is accessed less frequently, while the Archive tier is designed for rarely accessed data that can tolerate higher retrieval latency. Choosing the appropriate access tier can help organizations optimize storage costs according to usage patterns. The Hot tier is therefore appropriate for frequently accessed blob data.

Question 145

Which Azure service provides a managed hybrid and multicloud management capability by extending Azure management to resources outside Azure?

This makes it useful for web applications that require intelligent application-level traffic management. Blob Storage provides object storage, Service Bus provides messaging, and Key Vault protects secrets and keys. Application Gateway is therefore a suitable service when an application requires regional web traffic distribution with application-layer capabilities.

Question 154

Which Azure service provides content caching and delivery from locations closer to users around the world?

  1. Azure Site Recovery
  2. Azure CDN
  3. Azure Policy
  4. Azure Database for PostgreSQL

Correct Answer: 2

Explanation

Azure Content Delivery Network, or CDN, caches supported content at strategically located edge points so that users can retrieve content from locations closer to them. This can reduce latency and improve the performance of applications that deliver static or cacheable content such as images, videos, scripts, and web assets. Site Recovery focuses on disaster recovery, Policy provides governance, and PostgreSQL provides managed database functionality. Azure CDN is therefore useful when organizations need to improve global content delivery and reduce the distance between users and cached content.

Question 155

Which Azure feature allows administrators to prevent accidental deletion or modification of important resources?

  1. Azure Resource Manager locks
  2. Azure Event Hubs
  3. Azure Traffic Manager
  4. Azure Functions

Correct Answer: 1

Explanation

Azure resource locks help prevent accidental deletion or modification of important resources. The two primary lock types are ReadOnly and CanNotDelete. A ReadOnly lock prevents changes to the resource, while a CanNotDelete lock prevents deletion but allows authorized modifications. Locks can be applied at different scopes, including subscriptions, resource groups, and resources. Event Hubs handles event ingestion, Traffic Manager performs DNS-based routing, and Functions provides serverless compute. Resource locks are therefore an important governance feature for protecting critical Azure resources from unintended actions.

Question 156

Which Azure identity feature allows applications to access supported Azure resources without storing credentials in application code?

  1. Azure Service Health
  2. Azure Managed Identities
  3. Azure Load Balancer
  4. Azure Advisor

Correct Answer: 2

Explanation

Azure managed identities provide an identity for applications and Azure resources so they can authenticate to supported services without requiring developers to store credentials in application code. Azure can manage the identity credentials automatically, reducing the need to maintain secrets manually. Managed identities can work with role-based access control and supported Azure services. Service Health provides platform health information, Load Balancer distributes traffic, and Advisor provides recommendations. Managed identities are therefore useful for improving application security by reducing the exposure and management of stored credentials.

Question 157

Which Azure storage redundancy option replicates data to a secondary geographic region?

  1. LRS
  2. ZRS
  3. GRS
  4. Premium SSD

Correct Answer: 3

Explanation

Geo-redundant storage, or GRS, replicates data to a secondary Azure region that is geographically separate from the primary region. This provides additional protection against a major regional outage. Data is maintained redundantly in the primary location and asynchronously replicated to the secondary region. LRS provides redundancy within a single location, while ZRS spreads replicas across availability zones in one region. Premium SSD refers to a managed disk performance option rather than a storage account redundancy model. GRS is therefore appropriate when geographic disaster protection is required.

Question 158

Which Azure service is designed to transfer large amounts of data to Azure using a physical device when network transfer is impractical?

  1. Azure Data Box
  2. Azure Monitor
  3. Azure Logic Apps
  4. Azure WAF

Correct Answer: 1

Explanation

Azure Data Box is a service that helps organizations transfer large amounts of data to or from Azure using a Microsoft-provided physical device. It is particularly useful when moving very large datasets over a network would take too long or be impractical because of bandwidth limitations. Data can be copied to the device and returned to Microsoft for transfer into Azure. Azure Monitor handles monitoring, Logic Apps automates workflows, and WAF protects web applications. Data Box is therefore useful for large-scale offline data transfer scenarios.

Question 159

Which Azure concept refers to the ability of a system to automatically increase or decrease resources according to demand?

  1. High availability
  2. Fault tolerance
  3. Elasticity
  4. Governance

Correct Answer: 3

Explanation

Elasticity refers to the ability of a cloud environment to dynamically increase or decrease resources as workload demand changes. For example, an application may require additional compute capacity during periods of high traffic and reduce capacity when demand falls. This can help organizations maintain performance while avoiding unnecessary resource consumption. High availability focuses on keeping services accessible, fault tolerance focuses on continuing operation despite failures, and governance concerns management and compliance. Elasticity is therefore an important cloud characteristic for workloads with changing resource requirements.

Question 160

Which Azure service provides recommendations based on best practices but does not automatically enforce those recommendations as governance rules?

  1. Azure Policy
  2. Azure Resource Manager
  3. Azure Advisor
  4. Microsoft Entra ID

Correct Answer: 3

Explanation

Azure Advisor provides personalized recommendations intended to help improve areas such as cost, performance, reliability, and security. These recommendations inform administrators about potential improvements but do not function as mandatory governance rules. Azure Policy is used to define and enforce organizational standards, while Resource Manager provides a management layer for Azure resources. Microsoft Entra ID manages identities and access. Advisor is therefore the appropriate service when an organization wants guidance and best-practice recommendations rather than automatic enforcement of configuration requirements.
