• Question 63:

  A company's current billing agreement is static. If the company were to migrate to an entirely IaaS-based setup, which of the following billing concepts would the company be adopting?

  A. Enterprise agreement

  B. Perpetual

  C. Variable cost

  D. Fixed cost

  Correct Answer: C

  Explanation: Variable cost is a billing concept that means the customer pays only for the resources they consume, and the cost varies depending on the usage. This is different from fixed cost, which means the customer pays a predetermined amount regardless of the usage. IaaS-based setups typically use variable cost billing, as the customer can provision and deprovision resources on demand, and only pay for what they use. This allows the customer to optimize their costs and scale their resources according to their needs123.

• Question 65:

  The Chief Financial Officer for a company that operates a popular SaaS application has noticed compute costs from the CSP are extremely high but storage costs are relatively low. Which of the following does the company MOST likely operate?

  A. An email application

  B. A CDN service

  C. A gaming application

  D. Audio streaming service

  Correct Answer: C

  Explanation: A gaming application is a type of SaaS application that requires high compute resources to run the game logic, graphics, physics, and networking. Gaming applications also need to handle a large number of concurrent users and provide low latency and high performance. Therefore, the compute costs from the CSP would be extremely high for a gaming application. On the other hand, a gaming application does not need much storage space, as most of the game data is stored on the client side or in memory. Therefore, the storage costs from the CSP would be relatively low for a gaming application. The other options are not likely to have high compute costs and low storage costs. An email application, a CDN service, and an audio streaming service all need to store large amounts of data on the cloud, which would increase the storage costs. An email application and a CDN service do not need much compute power, as they mainly involve sending and receiving data. An audio streaming service may need some compute power to process and encode the audio files, but not as much as a gaming application. Therefore, the correct answer is C. A gaming application.

• Question 67:

  Which of the following would be expected from a security consultant who has been hired to investigate a data breach of a private cloud instance?

  A. Incident report

  B. Application scan results

  C. Request for information

  D. Risk register

  Correct Answer: A

  Explanation: An incident report is a document that summarizes the details of a security breach, such as the cause, impact, response, and lessons learned. It is expected from a security consultant who has been hired to investigate a data breach of a private cloud instance, as it provides a clear and concise account of what happened and how to prevent or mitigate future incidents. An incident report is also useful for communicating with stakeholders, regulators, customers, and other parties who may be affected by the breach. Application scan results are the output of a tool that scans an application for vulnerabilities, such as SQL injection, cross-site scripting, or broken authentication. They are not expected from a security consultant who has been hired to investigate a data breach of a private cloud instance, as they are more relevant for the development and testing phases of the application lifecycle. Application scan results may help identify potential weaknesses in the application, but they do not provide a comprehensive analysis of the breach. A request for information is a document that solicits information from vendors or service providers, such as their capabilities, pricing, or references. It is not expected from a security consultant who has been hired to investigate a data breach of a private cloud instance, as it is more relevant for the procurement and evaluation phases of the cloud service lifecycle. A request for information may help compare different cloud service options, but it does not provide a detailed report of the breach. A risk register is a document that records the risks associated with a project or an organization, such as their likelihood, impact, mitigation strategies, and status. It is not expected from a security consultant who has been hired to investigate a data breach of a private cloud instance, as it is more relevant for the risk management and governance phases of the cloud service lifecycle. A risk register may help identify and prioritize the risks that need to be addressed, but it does not provide a specific report of the breach.

• Question 70:

  Which of the following is achieved by implementing replication, redundancy, and disaster recovery?

  A. Improved performance

  B. Improved throughput

  C. Improved latency

  D. Improved availability

  Correct Answer: D

  Explanation: Availability is the degree to which a system or service is accessible and functional when required. Availability can be measured by metrics such as uptime, downtime, and service level agreements (SLAs). Availability can be improved by implementing replication, redundancy, and disaster recovery strategies in the cloud. Replication is the process of creating and maintaining multiple copies of data or resources across different locations or regions. Redundancy is the provision of extra or backup components or systems to prevent or mitigate failures. Disaster recovery is the ability to restore normal operations after a disruptive event, such as a natural disaster, a cyberattack, or a human error. By implementing these strategies, cloud users can ensure that their data and services are always accessible and resilient to failures or disasters.
