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?

Question 2

A systems administrator is planning to deploy a database cluster in a virtualization environment. The administrator needs to ensure the database nodes do not exist on the same physical host. Which of the following would best meet this requirement?

Answer : B

Anti-affinity is a rule that specifies that certain virtual machines should not run on the same physical host. This can help to improve availability and performance by avoiding single points of failure and resource contention. For example, if the database nodes are running on the same host and the host fails, the entire database cluster will be unavailable. By using anti-affinity rules, the systems administrator can ensure the database nodes are distributed across different hosts in the virtualization environment.Reference: CompTIA Cloud+ CV0-003 Study Guide, Chapter 2: Deploying a Cloud Environment, page 76.

Question 3
Question 4

An organization located in Asia connects to a cloud infrastructure hosted in North America and Europe. Sporadic slowness has been observed when using the PaaS and laaS components. A diagnostic using the following commands was run, and the following results were collected:

Which of the following is the most likely reason for the latency?

Question 5

Based on the shared responsibility model, which of the following solutions passes the responsibility of patching the OS to the customer?

Answer : C

IaaS stands for Infrastructure as a Service, and it is a cloud service model that provides customers with access to virtualized computing resources, such as servers, storage, and networks. In the IaaS model, the customer is responsible for patching the operating system (OS) of the virtual machines, as well as installing and managing the applications and dat

a. The cloud service provider (CSP) is responsible for maintaining the physical infrastructure, such as the hardware, power, cooling, and security. Therefore, IaaS passes the responsibility of patching the OS to the customer, unlike PaaS, DBaaS, or SaaS, where the CSP handles the OS patching and updates.

Question 6

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).

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.

Question 7

A VDI provider suspects users are installing prohibited software on the instances. Which of the following must be implemented to prevent the issue?

Answer : D

System hardening is the process of securing a system by reducing its attack surface and eliminating unnecessary services, features, or functions. System hardening can help prevent users from installing prohibited software on the VDI instances by applying policies and restrictions that limit the user privileges and access rights. For example, system hardening can disable the installation of software from unknown sources, enforce the use of strong passwords, enable encryption, and remove default accounts. System hardening can also improve the performance and stability of the VDI instances by removing unwanted or unused components.
