CompTIA Cloud+ Changed CV0-003 Questions

The answer is B. A VPN tunnel. A VPN tunnel is a secure and encrypted connection between two networks over a public network, such as the Internet. A VPN tunnel can help protect data in transit by encrypting it before it leaves the company’s network and decrypting it when it reaches the public cloud service provider. A VPN tunnel can also authenticate the endpoints and verify the integrity of the data.

Some possible sources of information about VPN tunnels are:

• [Cloud VPN overview | Google Cloud]: This page provides an overview of Cloud VPN, a service that creates secure and reliable VPN tunnels to Google Cloud.

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. References: [CompTIA Cloud+ CV0-003 Study Guide], Chapter 4, Objective 4.2: Given a scenario, troubleshoot common virtualization issues.

Single sign-on (SSO) is a technology that allows a user to access multiple applications or services with a single login and authentication process. SSO can enhance security by reducing the number of passwords that a user has to remember and enter, and by enabling centralized management and enforcement of security policies .

SSO can help address the issue of multiple SaaS-based cloud applications requiring authentication upon access. By implementing SSO, an administrator can:

Simplify the user experience and increase productivity by eliminating the need to enter multiple usernames and passwords for different applications .

Improve the security and compliance of the applications by using a trusted identity provider (IdP) that can verify the user’s identity and credentials, and grant or deny access based on predefined rules .

Reduce the risk of password breaches, phishing, or identity theft by minimizing the exposure of passwords to third-party applications or malicious actors .

SOA stands for Start of Authority, and it is a type of DNS record that contains information about a DNS zone, such as the name of the primary name server, the email address of the zone administrator, the serial number of the zone, and other parameters. The serial number is used to indicate when a zone has been updated, and it is incremented by the primary name server whenever a change is made to the zone data. The secondary name servers use the serial number to determine if they need to request a zone transfer from the primary name server to synchronize their data.
