Following a ransomware attack, the legal department at a company instructs the IT administrator to store the data from the affected virtual machines for a minimum of one year.
Which of the following is this an example of?

  1. Recoverability
  2. Retention
  3. Encryption
  4. Integrity

Answer(s): B

Explanation:

Retention refers to the policy or practice of storing data for a specified period, often for legal, regulatory, or business continuity reasons. In this case, the legal department requires the data to be stored for a minimum of one year, which is an example of a data retention requirement.



An engineer made a change to an application and needs to select a deployment strategy that meets the following requirements:
-Is simple and fast
-Can be performed on two identical platforms
Which of the following strategies should the engineer use?

  1. Blue-green
  2. Canary
  3. Rolling
  4. In-place

Answer(s): A

Explanation:

Blue-green deployment is a strategy where two identical environments (blue and green) are used. The new version of the application is deployed to one environment (e.g., green), while the other environment (e.g., blue) continues serving users. Once the new version is verified, traffic is switched to the new environment, making the change simple and fast. This strategy works well when two identical platforms are available.



An organization needs to retain its data for compliance reasons but only when required.
Which of the following would be the most cost-effective type of tiered storage?

  1. Warm
  2. Hot
  3. Archive
  4. Cold

Answer(s): C

Explanation:

Archive storage is designed for long-term data retention at a low cost. It is ideal for data that does not need to be accessed frequently but must be retained for compliance or regulatory reasons. Archive storage is typically the most cost-effective option for infrequent access.



An e-commerce store is preparing for an annual holiday sale. Previously, this sale has increased the number of transactions between two and ten times the normal level of transactions. A cloud administrator wants to implement a process to scale the web server seamlessly. The goal is to automate changes only when necessary and with minimal cost.
Which of the following scaling approaches should the administrator use?

  1. Scale horizontally with additional web servers to provide redundancy.
  2. Allow the load to trigger adjustments to the resources.
  3. When traffic increases, adjust the resources using the cloud portal.
  4. Schedule the environment to scale resources before the sale begins.

Answer(s): B

Explanation:

Allowing the load to trigger adjustments to the resources (also known as auto-scaling based on demand) is a dynamic approach where additional resources are automatically added or removed based on actual traffic load. This method ensures that scaling occurs only when necessary, optimizing costs by avoiding over-provisioning.



Which of the following vulnerability management phases includes the process of discovering newly introduced security vulnerabilities?

  1. Scanning
  2. Identification
  3. Reporting
  4. Remediation

Answer(s): A



A developer sends multiple requests to a SaaS application in a short amount of time. The developer realizes that the entire server and all other users can no longer send requests to the application.
Which of the following best describes the issue?

  1. Service quotas
  2. API rate limiting
  3. Full outage
  4. Regional service availability

Answer(s): B

Explanation:

API rate limiting is a mechanism used by SaaS applications to prevent abuse by limiting the number of requests that can be made to an API within a specified time frame. If the developer sent too many requests in a short period, the application may have triggered rate limiting, causing temporary blocks on further requests from the server or affecting all users if the limits were exceeded on a shared resource.



A cloud engineer needs to integrate a new payment processor with an existing e-commerce website.
Which of the following technologies is the best fit for this integration?

  1. RPC over SSL
  2. Transactional SQL
  3. REST API over HTTPS
  4. Secure web socket

Answer(s): C

Explanation:

REST API over HTTPS is widely used for integrating external services, like payment processors, with web applications. REST APIs are secure, reliable, and allow for standardized communication over HTTP/HTTPS, which is crucial for secure data transmission in payment processing.



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?

  1. SQL injection
  2. Cross-site scripting
  3. Leaked credentials
  4. DDoS

Answer(s): D

Explanation:

The logs show a high volume of GET requests to the /home endpoint within a very short time frame (one request per second or even multiple per second). This pattern is consistent with a DDoS attack, where an excessive number of requests are made to overload the server, causing it to crash or return errors (as seen with the 502 status codes).
