A systems administrator is troubleshooting a VDI deployment that is used to run high-frame-rate rendering. Users are reporting frequent application crashes. After running a benchmark, the administrator discovers the following:
Which of the following should the administrator do to resolve this issue?
Correct : C
The benchmark results show that the video RAM utilization is at 99%, which is likely causing the application crashes. Video RAM is used to store graphics data and textures that are processed by the GPU. Selecting a higher vGPU profile can help allocate more video RAM to the virtual machines, which can help resolve this issue. A vGPU profile is a predefined configuration that specifies the amount of video RAM, the number of display heads, and the maximum resolution that a virtual machine can use. By selecting a higher vGPU profile, the administrator can increase the performance and stability of the high-frame-rate rendering application.Reference: [CompTIA Cloud+ CV0-003 Study Guide], Chapter 4, Objective 4.2: Given a scenario, troubleshoot common virtualization issues.

A new development team requires workstations hosted in a PaaS to develop a new website. Members of the team also require remote access to the workstations using their corporate email addresses. Which of the following solutions will best meet these requirements? (Select two).
Correct : C, D
To meet the requirements of the development team, the cloud administrator should integrate identity services and implement a VDI solution. Identity services are used to authenticate and authorize users and devices to access cloud resources. By integrating identity services, the cloud administrator can enable the development team to use their corporate email addresses to log in to the PaaS workstations. A VDI solution is a virtualization technology that allows users to access remote desktops hosted on a cloud platform. By implementing a VDI solution, the cloud administrator can provide the development team with workstations that have the necessary tools and configurations for web development.

A cloud administrator has deployed a website and needs to improve the site security to meet requirements. The website architecture is designed to have a DBaaS in the back end and autoscaling instances in the front end using a load balancer to distribute the request. Which of the following will the cloud administrator most likely use?
Correct : D
A web application firewall (WAF) is a security solution that monitors and filters the traffic between a web application and the Internet. A WAF can help improve the site security by blocking malicious requests, preventing SQL injection attacks, mitigating cross-site scripting (XSS) attacks, and enforcing security policies. A WAF can be deployed as a cloud service or as a device in front of the load balancer. A WAF is more suitable than an API gateway, an IPS/IDS, or a reverse proxy for the website architecture described in the question.

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

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).
Correct : 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.
