CompTIA CV0-004 Online Questions & Answers

• Question 181:

  An organization's large e-commerce website requires high availability and cannot have degraded performance.

  Which of the following should a cloud administrator do to best meet the requirements?

  A. Create a secondary server and load balance the traffic.
  B. Upgrade the drives to SSD and change the storage tier.
  C. Add a secondary NIC and configure network teaming to the existing server.
  D. Change the type of CPU and adjust the RAM size.
  A. Create a secondary server and load balance the traffic.

  ---

  Explanation

  Creating a secondary server with load balancing distributes traffic, ensuring high availability and preventing performance degradation.

• Question 182:

  A company receives files daily from a bank. The company requires that the files must be copied from the cloud storage resource to another cloud storage resource for further processing.

  Which of the following methods requires the least amount of effort to achieve the task?

  A. Remote procedure call
  B. SOAP
  C. Event-driven architecture
  D. REST
  C. Event-driven architecture

  ---

  Explanation

  An event-driven architecture is the most efficient method for automating the task of copying files from one cloud storage resource to another upon their arrival. This architecture allows systems to automatically trigger actions based on specific events, such as the arrival of new files, minimizing manual effort and ensuring timely processing.

• Question 183:

  A manager wants information about which users signed in to a certain VM during the past month.

  Which of the following can the cloud administrator use to obtain this information?

  A. Retention
  B. Alerting
  C. Aggregation
  D. Collection
  D. Collection

  ---

  Explanation

  To obtain information about which users signed in to a certain VM during the past month, a cloud administrator can use log collection. Log collection involves gathering and storing logs from various sources, including VMs, to provide historical data on system access and activity, which can then be analyzed to identify user login instances.

  References:

  The CompTIA Cloud+ certification emphasizes the importance of monitoring and visibility in cloud environments, which includes log collection and analysis as key components of operational management and security monitoring.

• Question 184:

  Which of the following allows network access to services deployed in a container?

  A. Forward proxy
  B. Network orchestration
  C. Host affinity
  D. Port mapping
  D. Port mapping

  ---

  Explanation

  Port mapping exposes a port on the host machine and maps it to a port inside the container. This allows external network traffic to reach services running inside the container by directing requests from the host port to the containerized application port.

• Question 185:

  HOTSPOT

  A highly regulated business is required to work remotely and the risk tolerance is very low. You are tasked with providing an identity solution to the company cloud that includes the following:

  1. secure connectivity that minimizes user login 2. tracks user activity and monitors for anomalous activity 3. requires secondary authentication

• Question 186:

  An organization hosts its own data center. It has recently migrated some of its applications to the cloud, but some applications remain in its data center.

  Which of the following best describes the organization's cloud deployment model?

  A. Community
  B. Private
  C. Hybrid
  D. Public
  C. Hybrid

  ---

  Explanation

  A hybrid cloud deployment model combines on-premises infrastructure with cloud services. Since the organization continues to host some applications in its own data center while running others in the cloud, it is operating in a hybrid environment.

• Question 187:

  Which of the following reduces the chance of introducing a misconfiguration into cloud deployment templates?

  A. Performing a git fetch after every commit
  B. Opening pull requests for changes
  C. Using the web interface to update files
  D. Committing updates to the main branch
  B. Opening pull requests for changes

  ---

  Explanation

  Pull requests (PRs) are a key part of code review processes in version control systems like Git. By requiring pull requests before merging changes into the main branch, teams can review, validate, and test changes before they go live. This helps catch misconfigurations early, ensuring that cloud deployment templates remain secure and function correctly. A peer review process via pull requests reduces errors and enforces best practices before updates are integrated.

• Question 188:

  A cloud administrator needs to reduce storage costs.

  Which of the following would best help the administrator reach that goal?

  A. Enabling compression
  B. Implementing deduplication
  C. Using containers
  D. Rightsizing the VMs
  B. Implementing deduplication

  ---

  Explanation

  Deduplication is a process by which redundant data is eliminated, thus reducing the size of the dataset.

  Deduplication with cloud storage reduces the storage requirements, along with the amount of data to be transferred over the network, resulting in faster and more efficient data protection operations 1.

  2. Deduplication can be applied at different levels, such as file-level, block-level, or byte-level, depending on the granularity and efficiency of the technique 3. Deduplication can also be performed at different locations, such as source, target, or cloud, depending on the architecture and design of the storage system

  3. By implementing deduplication, a cloud administrator can achieve significant data savings and optimize the cloud storage costs 4.

• Question 189:

  An organization wants to ensure its data is protected in the event of a natural disaster. To support this effort, the company has rented a colocation space in another part of the country.

  Which of the following disaster recovery practices can be used to best protect the data?

  A. On-site
  B. Replication
  C. Retention
  D. Off-site
  D. Off-site

  ---

  Explanation

  For an organization looking to protect its data in the event of a natural disaster, the best disaster recovery practice would be off-site replication. By renting a colocation space in another part of the country, the company can maintain copies of their data and critical systems in a geographically separate location, ensuring they are not affected by the same disaster.

• Question 190:

  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
  B. VPC peering

  ---

  Explanation

  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.
