• Question 231:

  A systems administrator is configuring a cloud solution for a vulnerability assessment to test the company's resources that are hosted in a public cloud. The solution must test the company's resources from an external user's perspective. Which of the following should the systems administrator configure?

  A. An agent-based scan
  B. A network-based scan
  C. A port scan
  D. A credentialed scan
  B. A network-based scan

  ---

  Explanation

  A network-based scan is a type of vulnerability assessment that tests the security of a system or a network from an external user's perspective, without requiring any software or credentials on the target. A network-based scan can identify vulnerabilities such as open ports, misconfigured firewalls, outdated software, or exposed services .

• Question 232:

  After announcing a big sales promotion, an e-commerce company starts to experience a slow response on its platform that is hosted in a public cloud. When checking the resources involved, the systems administrator sees the following consumption: Considering all VMs were built from the same templates, which of the following actions should the administrator perform FIRST to speed up the response of the e-commerce platform?

  

  A. Spin up a new web server
  B. Spin up a new application server
  C. Add more memory to the web server
  D. Spin up a new database server
  D. Spin up a new database server

  ---

  Explanation

  Spinning up a new web server is what the administrator should perform first to speed up the response of the e-commerce platform that is hosted in a public cloud and starts to experience a slow response after announcing a big sales promotion. A web server is a system or service that hosts and delivers web content, such as web pages, images, videos, etc., to clients over a network or internet connection. A web server can affect the response of an e-commerce platform by determining how fast it can process and serve web requests or responses from clients. Spinning up a new web server can speed up the response of an e-commerce platform by providing benefits such as: Scalability: Spinning up a new web server can increase the scalability of the e- commerce platform by adding more capacity or resources to handle the increased demand or load caused by the sales promotion, without affecting the existing web servers. Performance: Spinning up a new web server can improve the performance of the e-commerce platform by reducing the latency or overhead of processing and serving web requests or responses from clients, which may cause delays or errors.

• Question 236:

  Which of the following should be considered for capacity planning?

  A. Requirements, licensing, and trend analysis
  B. Laws and regulations
  C. Regions, clusters, and containers
  D. Hypervisors and scalability
  A. Requirements, licensing, and trend analysis

  ---

  Explanation

  These are the factors that should be considered for capacity planning in a cloud environment. Capacity planning is a process of estimating and allocating the necessary resources and performance to meet the current and future demands of

  cloud applications or services. Capacity planning can help to optimize costs, efficiency, and reliability of cloud resources or services. The factors that should be considered for capacity planning are:

  Requirements: These are the specifications or expectations of the cloud applications or services, such as functionality, availability, scalability, security, etc. Requirements can help to determine the type, amount, and quality of resources or

  services needed to meet the objectives and goals of the cloud applications or services.

  Licensing: This is the agreement or contract that grants customers the right to use or access certain cloud resources or services for a specific period or fee. Licensing can affect the cost, availability, and compliance of cloud resources or

  services. Licensing can help to determine the budget, duration, and scope of using or accessing cloud resources or services.

  Trend analysis: This is the technique of analyzing historical and current data to identify patterns, changes, or fluctuations in demand or usage of cloud resources or services. Trend analysis can help to predict and anticipate future demand or

  usage of cloud resources or services, as well as identify any opportunities or challenges that may arise.

• Question 237:

  A systems administrator is reviewing the application development process with the development team and notices that the team has no way to collaboratively develop code. Which of the following methods should be implemented to resolve this issue?

  A. Continuous deployment.
  B. Version control.
  C. Change management.
  D. Configuration management.
  B. Version control.

  ---

  Explanation
