• Question 121:

  Which of the following industry standards mentions that credit card data must not be exchanged or stored in cleartext?

  A. CSA

  B. GDPR

  C. SOC2

  D. PCI-DSS

  Correct Answer: D

  The Payment Card Industry Data Security Standard (PCI-DSS) is the industry standard that mandates that credit card data must not be stored or transmitted in cleartext. It includes requirements for encryption, access control, and other security measures to protect cardholder data. References: Official PCI Security Standards Council Site.

• Question 122:

  A company wants to combine solutions in a central and scalable environment to achieve the following goals:

  1.

  Control

  2.

  Visibility

  3.

  Automation

  4.

  Cost efficiency

  Which of the following best describes what the company should implement?

  A. Batch processing

  B. Workload orchestration

  C. Containerization

  D. Application modernization

  Correct Answer: B

  Workload orchestration is the best description of what the company should implement to achieve control, visibility, automation, and cost efficiency. It involves using orchestration tools to manage workloads in cloud environments, ensuring

  resources are used efficiently and operations are automated.

  References: Workload orchestration is a part of cloud management strategies discussed under the Management and Technical Operations domain in the CompTIA Cloud+ objectives.

• Question 123:

  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

  Correct Answer: A

  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.

• Question 124:

  A cloud solutions architect is designing a VM-based solution that requires reducing the cost as much as possible. Which of the following solutions will best satisfy this requirement?

  A. Using ephemeral storage on replicated VMs

  B. Creating Spot VMs in one availability zone

  C. Spreading the VMs across different regions

  D. Using provisioned IOPS storage

  Correct Answer: B

  Using Spot VMs is a cost-effective solution as these are available at significantly reduced prices compared to standard instances. Spot VMs are ideal for workloads that can tolerate interruptions and are a way to take advantage of unused

  cloud capacity.

  References: The concept of Spot VMs and their cost benefits are included in the financial aspects of managing cloud resources, as per the CompTIA Cloud+ certification guidelines.

• Question 125:

  A cloud engineer needs to determine a scaling approach for a payroll-processing solution that runs on a biweekly basis. Given the complexity of the process, the deployment to each new VM takes about 25 minutes to get ready.

  Which of the following would be the best strategy?

  A. Horizontal

  B. Scheduled

  C. Trending

  D. Event

  Correct Answer: B

  For a biweekly payroll-processing solution that takes a significant amount of time to deploy to each new VM, the best scaling strategy is Scheduled scaling. This strategy involves preparing new instances in advance of when they are needed based on a known schedule, which in this case is the biweekly payroll process. By scheduling the scaling actions in advance, the cloud engineer ensures that the resources are ready when needed without incurring extra costs for running them all the time.

• Question 126:

  A company's man web application is no longer accessible via the internet. The cloud administrator investigates and discovers the application is accessible locally and only via an IP access. Which of the following was misconfigured?

  A. IP

  B. DHCP

  C. NAT

  D. DNS

  Correct Answer: D

  When a web application is accessible locally via an IP address but not via the internet, the issue likely lies with the Domain Name System (DNS). DNS is responsible for translating domain names into IP addresses. A misconfiguration in DNS records or failure in DNS resolution can prevent users from accessing the application through its domain name, even though the application itself is running and accessible via its direct IP address. References: In the CompTIA Cloud+ curriculum, understanding cloud concepts and networking fundamentals, including DNS, is crucial for troubleshooting and ensuring applications are accessible and perform optimally in cloud environments.

• Question 127:

  Which of the following provides secure, private communication between cloud environments without provisioning additional hardware or appliances?

  A. VPN

  B. VPC peering

  C. BGP

  D. Transit gateway

  Correct Answer: B

  VPC peering provides secure, private communication between cloud environments without the need for provisioning additional hardware or appliances. It allows direct network connectivity between two Virtual Private Clouds (VPCs), enabling

  resources in either VPC to communicate with each other using private IP addresses.

  References: Cloud networking options such as VPC peering and its benefits are included in the networking concepts of cloud environments in the CompTIA Cloud+ certification.

• Question 128:

  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?

  A. Warm

  B. Hot

  C. Archive

  D. Cold

  Correct Answer: C

  Archive storage is the most cost-effective type of tiered storage for retaining data that is infrequently accessed and only when required for compliance reasons. It is designed for long-term storage and offers lower storage costs compared to

  hot, cold, or warm storage tiers.

  References: Understanding data storage and the various tiers, including archival storage, is part of cloud storage strategies covered in the CompTIA Cloud+ certification.

• Question 129:

  Which of the following is a field of computer science that enables computers to identify and understand objects and people in images and videos?

  A. Image reconstruction

  B. Facial recognition

  C. Natural language processing

  D. Computer vision

  Correct Answer: D

  Computer vision is a field of computer science that enables computers to identify and understand objects and people in images and videos. It involves the development of systems that can capture and interpret visual information from the

  world, similar to the way humans do.

  References: The application of computer vision and its role in cloud services, particularly in relation to AI and machine learning capabilities, is discussed in CompTIA Cloud+.

• Question 130:

  The performance of an e-commerce website decreases dramatically during random periods. The IT team is evaluating available resources to mitigate the situation.

  Which of the following is the best approach to effectively manage this scenario?

  A. Migrating to a dedicated host

  B. Purchasing additional servers

  C. Scheduling resource allocation

  D. Configuring automatic elasticity

  Correct Answer: D

  Configuring automatic elasticity is the best approach to manage an e- commerce website that experiences random performance drops due to variable traffic. Automatic elasticity enables the cloud resources to scale up or down automatically

  based on the current load, ensuring consistent performance even during unexpected traffic surges.

  References: The concept of automatic elasticity is part of the cloud management and technical operations content in the CompTIA Cloud+ curriculum.
