NEW QUESTION # 56
A systems administrator receives an alert that VDI performance on the cluster is poor. Opening any application takes one to two minutes. The administrator investigates and finds the following conditions:
Cluster memory utilization: 65%
Cluster SSD utilization: 70%
Average VM CPU wait time: 14%
Cluster CPU utilization: 75%
Which of the following actions should the administrator take to improve VDI performance?
Answer: D
Explanation:
Detailed
A . Add CPU resources to the cluster: High CPU wait time indicates insufficient CPU resources for handling workload demands. Adding CPUs to the cluster will reduce latency and improve application performance.

NEW QUESTION # 57
All of a company's servers are currently hosted in one cloud MSP. The company created a new cloud environment with a different MSP. A cloud engineer is now tasked with preparing for server migrations and establishing connectivity between clouds. Which of the following should the engineer perform FIRST?
Answer: D
Explanation:
Creating a VPN tunnel is the first action that the engineer should perform to prepare for server migrations and establish connectivity between clouds. A VPN (Virtual Private Network) tunnel is a secure and encrypted connection that allows data to be transferred between two networks or locations over the public internet.
Creating a VPN tunnel can enable communication and interoperability between different cloud environments, as well as protect data from interception or modification during migration.

NEW QUESTION # 60
A security team is conducting an audit of the security group configurations for the Linux servers that are hosted in a public laaS. The team identifies the following rule as a potential
A cloud administrator, who is working remotely, logs in to the cloud management console and modifies the rule to set the source to "My IR" Shortly after deploying the rule, an internal developer receives the following error message when attempting to log in to the server using SSH: Network error: connection timed out.
However, the administrator is able to connect successfully to the same server using SSH. Which of the following is the BEST option for both the developer and the administrator to access the server from their locations?
Answer: D
Explanation:
Explanation
The inbound rule that the security team identified as a potential vulnerability is the one that allows SSH access (port 22) from any source (0.0.0.0/0). This means that anyone on the internet can try to connect to the Linux servers using SSH, which poses a risk of unauthorized access or brute-force attacks. The cloud administrator, who is working remotely, logs in to the cloud management console and modifies the rule to set the source to
"My IP". This means that only the administrator's IP address can connect to the Linux servers using SSH, which improves the security of the servers. However, this also prevents other authorized users, such as the internal developer, from accessing the servers using SSH, as they have different IP addresses than the administrator. Therefore, the administrator needs to modify the rule again to allow more sources for SSH access.
The best option for both the developer and the administrator to access the server from their locations is to modify the inbound rule to allow the company's external IP address as a source. This means that only the IP addresses that belong to the company's network can connect to the Linux servers using SSH, which reduces the attack surface and ensures that only authorized users can access the servers. The company's external IP address can be obtained by using a web service such as [What Is My IP Address?] or [IP Location]. The administrator can then enter this IP address or its CIDR notation in the source field of the inbound rule.
