CompTIA CompTIA Certifications CV0-004 Questions & Answers

• Question 281:

  HOTSPOT

  The QA team is testing a newly implemented clinical trial management (CTM) SaaS application that uses a business intelligence application for reporting. The UAT users were instructed to use HTTP and HTTPS.

  Refer to the application dataflow:

  1.

  1A -The end user accesses the application through a web browser to enter and view clinical data.

  2.

  2A -The CTM application server reads/writes data to/from the database server.

  3.

  1B -The end user accesses the application through a web browser to run reports on clinical data.

  4.

  2B -The CTM application server makes a SOAP call on a non-privileged port to the BI application server.

  5.

  3B -The BI application server gets the data from the database server and presents it to the CTM application server.

  When UAT users try to access the application using https://ctm.app.com or http://ctm.app.com, they get a message stating: "Browser cannot display the webpage." The QA team has raised a ticket to troubleshoot the issue.

  INSTRUCTIONS

  You are a cloud engineer who is tasked with reviewing the firewall rules as well as virtual network settings.

  You should ensure the firewall rules are allowing only the traffic based on the dataflow.

  You have already verified the external DNS resolution and NAT are working.

  Verify and appropriately configure the VLAN assignments and ACLs. Drag and drop the appropriate VLANs to each tier from the VLAN Tags table. Click on each Firewall to change ACLs as needed.

• Question 283:

  A small marketing company recently moved all of its storage to a cloud provider. The budget for storage has limited the company to buying a small amount of SSD storage and a lot of spinning disks. The storage administrator needs to find a way to optimize this environment to realize maximum speed.

  Which of the following would best achieve this?

  A. Compression

  B. Automated storage tiering

  C. Deduplication

  D. Autoscaling

  Correct Answer: B

  Automated storage tiering is a technique used to optimize storage performance by automatically moving data between different tiers of storage based on its access frequency and importance. In this scenario, since the company has limited SSD storage and a lot of spinning disks due to budget constraints, implementing automated storage tiering would allow frequently accessed and critical data to be stored on the faster SSD storage, while less frequently accessed data can be stored on the slower spinning disks. This would maximize speed for critical operations while efficiently utilizing the available resources.

• Question 284:

  A systems administrator wants to ensure a system can adjust its resources based on usage. Which of the following will best accomplish this goal?

  A. Anti-affinity

  B. Autoscaling

  C. Right-sizing

  D. Oversubscription

  Correct Answer: B

  Autoscaling is the best option to accomplish the goal of adjusting system resources based on usage. Autoscaling automatically adjusts the number of compute resources (such as virtual machines or containers) based on predefined conditions or metrics, such as CPU utilization, memory usage, or incoming network traffic. When demand increases, autoscaling can dynamically add more resources to handle the load, and when demand decreases, it can remove unnecessary resources to optimize costs.

• Question 285:

  A cloud administrator is choosing a backup schedule for a new application platform that creates many small files. The backup process impacts the performance of the application, and backup times should be minimized during weekdays.

  Which of the following backup types best meets the weekday requirements?

  A. Database dump

  B. Differential

  C. Incremental

  D. Full

  Correct Answer: C
