  Explanation

  Deploying web servers into an IaaS (Infrastructure as a Service) provider is the most suitable method to achieve the objective of hosting an external website and managing the OS. IaaS is a cloud service model that provides basic computing resources such as servers, storage, network, etc., to the customers. The customers have full control and flexibility over these resources and can install and configure any software they need on them. IaaS is suitable for hosting web servers and managing the OS, as it allows the customers to choose their preferred OS, web server software, settings, etc., and customize them according to their needs.

• Question 104:

  A company recently set up a CDN for its photography and image-sharing website. Which of the following is the most likely reason for the company's action?

  A. To eliminate storage costs
  B. To improve site speed
  C. To enhance security of static assets
  D. To prevent unauthorized access
  B. To improve site speed

  ---

  Explanation

  The most likely reason for setting up a Content Delivery Network (CDN) is to improve site speed, especially for a photography and image-sharing website. CDNs cache content at edge locations closer to end-users, significantly reducing load times for static assets like images and videos. This enhancement in speed can improve user experience and site performance.

• Question 105:

  A cloud administrator shortens the amount of time a backup runs. An executive in the company requires a guarantee that the backups can be restored with no data loss.

  Which of th following backup features should the administrator lest for?

  A. Encryption
  B. Retention
  C. Schedule
  D. Integrity
  D. Integrity

  ---

  Explanation

  To guarantee that backups can be restored with no data loss, the administrator should test for data integrity. This ensures that the data has not been altered during the backup process and that it can be restored to its original state. References:Backup integrity is a critical aspect of data management and protection, which falls under the best practices for backups and restoration in the CompTIA Cloud+ curriculum.

• Question 106:

  An administrator configures three subnets to the corporate network. All servers should communicate with the main corporate network and access the internet. The administrator creates the following configurations:

  

  After configuring the networks, the administrator recognizes an issue with the configuration.

  Which of the following can the administrator change in one step to accomplish the goal?

  A. Remove source 192.168.12.0/24 and destination 192.168.1.0/24 from the routing table.
  B. Replace destination 192.168.1.0/24 with destination 192.168.0.0/24.
  C. Add source 192.168.12.0/24 and destination 192.168.0.0/24 to the routing table.
  D. Reconfigure Network 4 to 192.168.13.0/24.
  B. Replace destination 192.168.1.0/24 with destination 192.168.0.0/24.

• Question 108:

  A company's website suddenly crashed. A cloud engineer investigates the following logs:

  

  Which of the following is the most likely cause of the issue?

  A. SQL injection
  B. Cross-site scripting
  C. Leaked credentials
  D. DDoS
  D. DDoS

  ---

  Explanation

  The logs indicate a sudden surge in access requests to the website's homepage, followed by 502 errors, which are indicative of server overload or failure to handle incoming requests. This pattern is typical of a Distributed Denial of Service (DDoS) attack, where multiple compromised systems flood the target with traffic, exceeding its capacity to handle requests, leading to service disruption.

• Question 109:

  A company just learned that the data in its object storage was accessed by an unauthorized party. Which of the following should the company have done to make the data unusable?

  A. The company should have switched from object storage to file storage.
  B. The company should have hashed the data.
  C. The company should have changed the file access permissions.
  D. The company should have encrypted the data at rest.
  D. The company should have encrypted the data at rest.

  ---

  Explanation

  Encrypting the data at rest is a crucial security measure to make the data unusable to unauthorized parties. If the object storage data was accessed by an unauthorized party, having the data encrypted would ensure that the data remains confidential and inaccessible without the proper encryption keys, thus mitigating the impact of the breach.

• Question 110:

  An organization's web application experiences periodic bursts of traffic when a new video is launched. Users are reporting poor performance in the middle of the month. Which of the following scaling approaches should the organization use to scale based on forecasted traffic?

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

  ---

  Explanation

  For periodic bursts of traffic that are predictable, such as when a new video is launched, a scheduled scaling approach is suitable. This strategy involves scaling resources based on forecasted or known traffic patterns, ensuring that the infrastructure can handle the load during expected peak times.

  References: The use of scheduled scaling to manage predictable traffic increases is discussed within the Management and Technical Operations section of the CompTIA Cloud+ exam objectives.
