  A. Alpha
  B. Beta
  C. Minor
  D. Major

  Explanation

• Question 132:

  A company has applications that need to remain available in the event of the data center being unavailable. The company's cloud architect needs to find a solution to maintain business continuity.

  Which of following should the company implement?

  A. A DR solution for the application between different data centers
  B. An off-site backup solution with a third-party vendor
  C. laC techniques to recreate the system at a new provider
  D. An HA solution for the application inside the data center
  A. A DR solution for the application between different data centers

  ---

  Explanation

  A disaster recovery (DR) solution is a set of policies, procedures, and tools that enable an organization to restore or continue its critical functions in the event of a natural or human-induced disaster. A DR solution for the application between different data centers means that the application is replicated or backed up to another location that is geographically separated from the primary data center. This way, if the primary data center becomes unavailable due to a power outage, fire, flood, cyberattack, or any other cause, the application can be switched over to the secondary data center and resume its operations with minimal downtime and data loss. This solution ensures business continuity and high availability for the application and its users.

• Question 133:

  A project manager is taking notes and gathering feedback from a previous project in order to consider known issues for a project enhancement. Which of the following best describes the plan being used?

  A. A plan for capturing issues and conflicts in a project knowledge base
  B. A plan for avoiding potential issues during project execution
  C. A plan for documenting project outcomes
  D. A plan for addressing and resolving issues after project completion
  A. A plan for capturing issues and conflicts in a project knowledge base

• Question 134:

  For compliance purposes, a cloud developer at an insurance company needs to save all customer policies for more than ten years. Which of the following options is the most cost-efficient tier to save the data in the cloud?

  A. Archive
  B. Hot
  C. Cold
  D. Warm
  A. Archive

  ---

  Explanation

  For compliance purposes, saving customer policies for more than ten years most cost-efficiently can be achieved by using the Archive storage tier. Archive or archival storage is designed for data that needs to be retained over the long term but accessed infrequently. It is generally the most cost-effective storage tier for this type of data.

• Question 135:

  A cloud server needs to automatically allocate more resources during sudden peak times. This allocation does not need to occur in regular intervals.

  Which of the following scaling approaches should be used?

  A. Event
  B. Manual
  C. Trending
  D. Scheduled
  A. Event

  ---

  Explanation

  Event-based scaling is designed to allocate more resources automatically in response to specific events, such as sudden peak times that are not regular or predictable. This type of scaling ensures that resources are available when needed without the need to schedule them in advance or adjust them manually.

• Question 136:

  A public cloud administrator needs to implement a mechanism to monitor the expense of the company's cloud resources. Which of the following options will allow the administrator to execute this task fastest way and with minimal effort?

  A. Set up daily expense reports with the cloud provider.
  B. Enable custom notifications for exceeding budget thresholds.
  C. Use the API to collect expense information from cloud resources.
  D. Implement a financial tool to monitor cloud resource expenses.
  D. Implement a financial tool to monitor cloud resource expenses.

• Question 137:

  A cloud engineer is reviewing a disaster recovery plan that includes the following requirements:

  1. System state, files, and configurations must be backed up on a weekly basis.

  2. The system state, file, and configuration backups must be tested annually.

  Which of the following backup methods should the engineer implement for the first week the plan is executed?

  A. Differential
  B. Incremental
  C. Snapshot
  D. Full
  D. Full

  ---

  Explanation

  A full backup method should be implemented for the first week the disaster recovery plan is executed. This will ensure that a complete copy of the system state, files, and configurations are backed up. Subsequent backups can be differential or incremental as per the plan.References: Backup methodologies, including the importance of full backups, are part of the data management strategies in cloud computing covered in the CompTIA Cloud+ certification.

• Question 138:

  A systems administrator created several new VMs on a private cloud and wants to ensure the new baseline still meets corporate guidelines. The administrator finds the following new load numbers on the hosts:

  

  If corporate policy requires N+1 host capacity, which of the following metrics is MOST likely to present a problem?

  A. CPU
  B. RAM
  C. DISK
  D. NETWORK
  C. DISK

  Explanation

• Question 139:

  A systems administrator has verified that a physical switchport that is connected to a virtualization host is using all available bandwidth. Which of the following would BEST address this issue?

  A. Port mirroring
  B. Link aggregation
  C. Spanning tree
  D. Microsegmentation
  B. Link aggregation

  ---

  Explanation

  Link aggregation, often referred to as "bonding" or "teaming," combines multiple physical network links into a single logical link. This provides increased bandwidth, fault tolerance, and load balancing. In the context of a virtualization host using all available bandwidth, implementing link aggregation would allow the host to utilize the combined bandwidth of multiple physical links, thus alleviating congestion and ensuring efficient use of network resources. This can significantly improve network performance for the virtualized environment.

• Question 140:

  A manager wants information about which users signed in to a certain VM during the past month. Which of the following can the cloud administrator use to obtain this information?

  A. Retention
  B. Alerting
  C. Aggregation
  D. Collection
  D. Collection

  ---

  Explanation

  To obtain information about which users signed in to a certain VM during the past month, a cloud administrator can use log collection. Log collection involves gathering and storing logs from various sources, including VMs, to provide historical data on system access and activity, which can then be analyzed to identify user login instances.References: The CompTIA Cloud+ certification emphasizes the importance of monitoring and visibility in cloud environments, which includes log collection and analysis as key components of operational management and security monitoring.
