A server in a remote data center is no longer responsive. Which of the following is the BEST solution to investigate this failure?
Answer: C
A systems administrator is attempting to install a package on a server. After downloading the package from the internet and trying to launch it, the installation is blocked by the antivirus on the server. Which of the following must be completed before launching the installation package again?
Answer: C
When downloading packages from the internet, especially for servers, it's crucial to ensure the integrity and authenticity of the package. This helps to ensure that the package hasn't been tampered with and that it's safe to install. The most common way to do this is by checking the checksum of the downloaded file against a known good checksum provided by the software vendor. Therefore, the best practice in this scenario is: C. Validating the checksum for the downloaded installation package. BUT, this question seems to assume the file has Integrity already

An administrator needs to increase the size of an existing RAID 6 array that is running out of available space. Which of the following is the BEST way the administrator can perform this task?
Answer: D
By replacing the drives one at a time and allowing the array to rebuild after each replacement, you can gradually increase the size of the array without losing data. Once all drives have been replaced, you can then expand the array to make use of the additional space. This approach minimizes the risk of data loss compared to replacing all drives at once.

An administrator has been asked to deploy a database server that provides the highest performance with fault tolerance. Which of the following RAID levels will fulfill this request?
Answer: E
A data center has 4U rack servers that need to be replaced using VMs but without losing any data. Which of the following methods will MOST likely be used to replace these servers?
Answer: C
An administrator is troubleshooting an application performance issue on a virtual server with two vCPUs. The application performance logs indicate CPU contention. The administrator adds more vCPU cores to the VM, yet the issue persists. Which of the following is the MOST likely reason for this issue?
Answer: C
C. The application is single-threaded. Adding more vCPU cores to a virtual machine may not necessarily improve performance if the application is single-threaded. In a single-threaded application, it can only effectively utilize one CPU core at a time. Even if more vCPUs are added, the application won't be able to take advantage of the additional cores, leading to continued CPU contention.

An administrator is alerted to an issue with server hardware deployed as a virtualization host. The alert indicates a predictive failure in a DIMM module. Which of the following is the BEST action for the administrator to take?
Answer: C
Here's why: It addresses the urgency of the predictive failure alert, reducing the risk of an actual failure occurring. Scheduling an outage allows for proper planning and notification to affected users or systems. It ensures the replacement can be done safely, with the system powered down, which is typically necessary for memory replacement. This approach balances the need for prompt action with the need for controlled, safe maintenance on a critical system. It allows for proper testing after replacement to ensure system stability. While scheduling an immediate outage may cause some short-term disruption, it's the safest and most responsible course of action given the critical nature of a virtualization host and the potential consequences of an actual memory failure. This approach minimizes the risk of unplanned downtime or data loss that could result from an actual failure of the DIMM module.
