• Question 142:

  Which of the following requirements are the most important when provisioning cloud resources for a client in the finance industry? (Choose two.)

  A. Cost
  B. Security
  C. Compute
  D. Network
  E. Storage
  F. Compliance
  G. Performance
  B. Security
  F. Compliance

  ---

  Explanation

  Security is critical in the finance industry because financial data is highly sensitive and must be protected against unauthorized access, breaches, and fraud.

  Compliance is equally important because financial organizations must adhere to strict regulatory and legal requirements governing data handling, privacy, auditing, and retention. Cloud resources must be provisioned in a manner that satisfies these regulatory obligations.

• Question 143:

  A web-application company recently released some new marketing promotions without notifying the IT staff.

  The systems administrator has since been noticing twice the normal traffic consumption every two hours for the last three hours in the container environment.

  Which of the following should the company implement to accommodate the new traffic?

  A. A firewall
  B. Switches
  C. Ballooning
  D. Autoscaling
  D. Autoscaling

  ---

  Explanation

  According to the CompTIA Cloud+ Study Guide1, autoscaling is "the ability to automatically increase or decrease the number of resources allocated to a cloud service based on the current demand". This means that autoscaling can help a cloud environment adjust to changes in traffic and workload, such as the ones caused by the new marketing promotions.

  Ballooning, on the other hand, is "a technique used by hypervisors to reclaim unused memory from a virtual machine and allocate it to another virtual machine that needs more memory". This means that ballooning can help optimize the memory usage of a cloud environment, but it does not affect the number of resources allocated to a cloud service. A firewall is "a device or software that monitors and controls the incoming and outgoing network traffic based on predefined rules". This means that a firewall can help protect a cloud environment from unauthorized access and malicious attacks, but it does not affect the number of resources allocated to a cloud service. Switches are "devices that connect multiple devices on a network and forward data packets between them". This means that switches can help improve the network performance and connectivity of a cloud environment, but they do not affect the number of resources allocated to a cloud service.

  Based on this information, I think the best answer to your question is D. Autoscaling. Autoscaling can help the company accommodate the new traffic by automatically increasing or decreasing the number of resources allocated to their web-application service based on the current demand. This can also help reduce costs and improve performance and availability.

  I hope this helps you understand the concept of autoscaling better. If you want to learn more about

• Question 144:

  A company wants to avoid vendor lock-in situations.

  Which of the following options should the company consider before doing business with a vendor? (Choose two.)

  A. Cost factor
  B. Open-source technologies
  C. Data portability
  D. Regulatory compliance
  E. Service availability
  F. Storage options
  B. Open-source technologies
  C. Data portability

  ---

  Explanation

  Open-source technologies help reduce dependence on proprietary platforms and interfaces, making it easier to switch providers or integrate with other environments. Data portability is also critical because the company must be able to move its data, workloads, and configurations to another vendor without major technical or financial barriers.

• Question 145:

  Users of a public website that is hosted on a cloud platform are receiving a message indicating the connection is not secure when landing on the website.

  The administrator has found that only a single protocol is opened to the service and accessed through the URL https://www.comptiasite.com.WhichofthefollowingwouldMOSTlikelyresolvetheissue?

  A. Renewing the expired certificate
  B. Updating the web-server software
  C. Changing the crypto settings on the web server
  D. Upgrading the users' browser to the latest version
  A. Renewing the expired certificate

  ---

  Explanation

  Renewing the expired certificate is what would most likely resolve the issue of users receiving a message indicating the connection is not secure when landing on a website that is hosted on a cloud platform and accessed through

  https://www.comptiasite.com.A

  certificate is a digital document that contains information such as identity, public key, expiration date, etc., that can be used to prove one's identity and establish secure communication over a network. A certificate can expire when it reaches its validity period and needs to be renewed or replaced. An expired certificate can cause users to receive a message indicating the connection is not secure by indicating that the website's identity or security cannot be verified or trusted.Renewingtheexpiredcertificatecanresolvetheissuebyextendingitsvalidityperiodandrestoringitsidentityorsecurityverificationortrust.

• Question 146:

  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

• Question 147:

  During a project kickoff meeting, the project manager wants to set expectations for all team members.

  Which of the following actions should the project manager take to accomplish this goal?

  A. Assign tasks and responsibilities to the team members
  B. Provide an overview of the project objectives and timeline
  C. Develop a project communication plan
  D. Set a meeting cadence for the rest of the project
  B. Provide an overview of the project objectives and timeline

  ---

  Explanation

  The kickoff meeting is held at the beginning of a project to establish direction and set expectations. The most important activity is to review the project objectives and the overall timeline so that all participants understand the project's scope and goals. Detailed task assignments and communication planning are typically addressed later during the planning and execution phases.

• Question 148:

  A cloud engineer is deploying a server in a cloud platform. The engineer reviews a security scan report.

  Which of the following recommended services should be disabled? (Select two).

  A. Telnet
  B. FTP
  C. Remote log-in
  D. DNS
  E. DHCP
  F. LDAP
  A. Telnet
  B. FTP

  ---

  Explanation

  Telnet and FTP are recommended services to be disabled when deploying a server in a cloud platform, as they are insecure protocols that transmit data in plain text and expose credentials and sensitive information to potential attackers 12. Remote log-in, DNS, DHCP, and LDAP are not necessarily recommended to be disabled, as they may provide useful functionality for the server and the cloud environment. However, they should be configured properly and secured with encryption, authentication, and authorization mechanisms 34.

• Question 149:

  A systems administrator needs to configure a script that will monitor whether an application is healthy and stop the VM if an unsuccessful code is returned.

  Which of the following scripts should the systems administrator use to achieve this goal?

  A. RESPONSE_CODE } string APP_URL bool RESPONSE_CODE string VM health checker (APP_URL, VM) { if [ http_probe (APP_URL) == 200] { echo RESPONSE_CODE } else{ stop (VM) echo
  B. else{ echo string APP_URL float RESPONSE_CODE string VM health_checker (APP_URL, VM) { if [ http_probe (APP_URL) == 200] { stop (RESPONSE_CODE) echo VM } stop (VM) RESPONSE CODE }
  C. else{ echo string APP_URL int RESPONSE CODE string VM health checker (APP_URL, VM) {if [ http_probe (APP_URL) == 200] { echo RESPONSE_CODE } stop (VM) RESPONSE_CODE }
  D. else{ echo string APP_URL int RESPONSE_CODE string VM health_checker (APP_URL, VM) { if [ http_probe (VM) == 200] { stop (VM) echo RESPONSE_CODE } RESPONSE CODE }
  A. RESPONSE_CODE } string APP_URL bool RESPONSE_CODE string VM health checker (APP_URL, VM) { if [ http_probe (APP_URL) == 200] { echo RESPONSE_CODE } else{ stop (VM) echo

  ---

  Explanation

  Script A is designed to monitor the health of an application by checking its response code. If the application returns a 200 (OK) status, it indicates that the application is healthy. Otherwise, the script will stop the VM to address the issue, which is a common approach to handle unhealthy application states in automated environments. This script effectively achieves the goal of monitoring application health and taking corrective action when an unsuccessful code is returned.
