I recently passed the CompTIA Cloud+ Certification Exam and I found the topics on Cloud Architecture and Design very helpful. Thanks to Pass4Success practice questions, I was able to understand the different cloud models and factors influencing capacity planning. One question that I remember from the exam was about the importance of high availability in cloud environments, which I initially found challenging but managed to answer correctly.

Free CompTIA CV0-003 Exam Actual Questions

Note: Premium Questions for CV0-003 were last updated On Jul. 12, 2024 (see below)

Question #1

An integration application that communicates between different application and database servers is currently hosted on a physical machine. A P2V migration needs to be done to reduce the hardware footprint. Which of the following should be considered to maintain the same level of network throughput and latency in the virtual server?

Reveal Solution Hide Solution
Correct Answer: C

SR-IOV stands for Single Root I/O Virtualization, which is a technology that allows a physical network adapter to be partitioned into multiple virtual functions (VFs) that can be directly assigned to virtual machines (VMs). This way, the network traffic bypasses the software layer of the hypervisor and the virtual switch, and goes directly from the VM to the physical adapter. This reduces the CPU overhead, the network latency, and the packet loss, and improves the network throughput and scalability. SR-IOV can achieve near-native performance for network-intensive applications, such as an integration application that communicates between different application and database servers. By enabling SR-IOV capability on the physical server and the virtual server, the P2V migration can maintain the same level of network throughput and latency as the original physical machine.Reference:High performance network virtualization with SR-IOV;Supercharge Your Network Throughput via Single Root I/O Virtualization (SR-IOV);Overview of Single Root I/O Virtualization (SR-IOV).


Question #2

A systems administrator deployed a new web application in a public cloud and would like to test it, but the company's network firewall is only allowing outside connections to the cloud provider network using TCP port 22. While waiting for the network administrator to open the required ports, which of the following actions should the systems administrator take to test the new application? (Select two).

Reveal Solution Hide Solution
Correct Answer: B, F

To test the new web application in the public cloud, the systems administrator should create a replica database, synchronize the data, and switch to the new instance, and create a SSH tunnel. Creating a replica database can help minimize the downtime and ensure data consistency during the migration. Synchronizing the data can help keep the replica database up to date with the original database. Switching to the new instance can help activate the new web application in the public cloud. Creating a SSH tunnel can help bypass the network firewall and access the web application using TCP port 22. SSH is a secure protocol that can create encrypted tunnels between the local and remote hosts. By creating a SSH tunnel, the systems administrator can forward the web application traffic through the tunnel and test it using a web browser. Reference: [CompTIA Cloud+ CV0-003 Certification Study Guide], Chapter 7, Objective 7.1: Given a scenario, migrate applications and data to the cloud.


Question #3

An integration application that communicates between different application and database servers is currently hosted on a physical machine. A P2V migration needs to be done to reduce the hardware footprint. Which of the following should be considered to maintain the same level of network throughput and latency in the virtual server?

Question #4

A cloud engineer recently used a deployment script template to implement changes on a cloud-hosted web application. The web application communicates with a managed database on the back end. The engineer later notices the web application is no longer receiving data from the managed database. Which of the following is the most likely cause of the issue?

Reveal Solution Hide Solution
Correct Answer: D

A misconfiguration in the firewall is the most likely cause of the issue. A firewall is a security device or service that controls the incoming and outgoing network traffic based on predefined rules. A firewall can help protect the cloud-hosted web application and the managed database from unauthorized or malicious access. However, if the firewall rules are not configured properly, they can also block the legitimate communication between the web application and the database. For example, if the firewall rules deny the port or protocol that the web application uses to connect to the database, the web application will not be able to receive data from the database. To fix this issue, the cloud engineer should review and update the firewall rules to allow the necessary traffic between the web application and the database. Reference:CompTIA Cloud+ CV0-003 Certification Study Guide, Chapter 9, Objective 9.2: Given a scenario, troubleshoot common security issues.
