• Question 252:

  Your company needs to store container images in a private repository and automatically scan them for vulnerabilities. What should you use?

  A. Azure Blob Storage
  B. Azure DevOps Repos
  C. Azure Container Registry with Defender for Containers
  D. Azure App Service
  C. Azure Container Registry with Defender for Containers

  ---

  Azure Container Registry (ACR) stores container images and integrates with Microsoft Defender for Containers for vulnerability scanning.

• Question 253:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  Data that is strored in an azure storage account automatically has at least three copies. Yes

• Question 254:

  You need to identify the type of failure for which an Azure availability zone can be used to protect access to Azure services. What should you identify?

  A. a physical server failure
  B. an Azure region failure
  C. a storage failure
  D. an Azure data center failure
  D. an Azure data center failure

  ---

  Azure Availability Zones are physically separate locations within an Azure region, each with independent power, networking, and cooling. Deploying resources across multiple availability zones protects against data center-level failures within the same region.

  Other options:

  "A physical server failure" . Incorrect. Availability Zones are overkill for a single server failure; standard VM redundancy or availability sets can handle this.

  "An Azure region failure" . Incorrect. Availability Zones are contained within a single region; they do not protect against entire regional outages.

  "A storage failure" . Incorrect. Specific storage redundancy options (like geo-redundant storage) protect against storage failures, not availability zones.

• Question 255:

  HOTSPOT

  Select the answer that correctly completes the sentence.

  

  

  Explanation:

  Azure resource manager templates use the JSON format.

• Question 256:

  Your company needs to ensure that Azure resources remain compliant with internal security standards and automatically remediate violations when possible. What should you recommend?

  A. Azure Policy with remediation tasks
  B. Azure Subscription locks
  C. Azure RBAC
  D. Azure App Service environment
  A. Azure Policy with remediation tasks

  ---

  Azure Policy can enforce and automatically remediate non-compliant configurations such as requiring encryption or specific tags. Locks prevent deletion/modification but do not handle compliance. RBAC controls permissions. App Service Environment is unrelated to compliance enforcement.

• Question 257:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

  NOTE: Each correct selection is worth one point.

  

  

  Explanation:

  You can associate a network security group to a virtual network subnet. Yes

• Question 258:

  How many copies of data are maintained by an Azure Storage account that uses locally-redundant storage (LRS)?

  A. 2
  B. 3
  C. 6
  D. 9
  B. 3

  ---

  Locally-redundant storage (LRS) maintains three copies of your data.

  All three copies are stored within a single data center in one Azure region.

  This protects against hardware failures while keeping costs low.

  Why the other answers are wrong:

  2:Azure does not use two-copy redundancy for LRS.

  6:Six copies are used with Zone-redundant storage (ZRS),

  where data is replicated across three availability zones.

  9:Nine copies are used with Geo-zone-redundant storage (GZRS),

  which combines zone replication and regional replication.

• Question 259:

  HOTSPOT

  For each of the following statements, select Yes if the statement is true. Otherwise, select No.

• Question 260:

  What is required to use Azure Cost Management?

  A. a Dev/Test subscription
  B. Software Assurance
  C. an Enterprise Agreement (EA)
  D. a pay-as-you-go subscription
  D. a pay-as-you-go subscription

  ---

  Azure Cost Management helps track, allocate, and optimize cloud spending.

  It is available for all Azure subscriptions that have a billing relationship, such as pay-as-you-go subscriptions.-Other options:

  Dev/Test subscription: designed for development/testing; may have limited cost management capabilities.

  Software Assurance: on-premises licensing benefit; not required for Cost Management.

  Enterprise Agreement (EA): provides volume licensing and billing options; useful but not required for Cost Management.
