While Cat 6a cables are typically recommended for reliable 10Gbps performance over longer distances due to their improved specifications and performance characteristics, Cat 6 cables can still support 10Gbps Ethernet over shorter distances, especially within the specifications of the standard.

Which of the following describes the BEST use case for a client-side hypervisor?
a. For a software developer who is required to test an application in many environments
b. When the data center environment is out of resources for a new server
c. As a cost-saving measure to allow multiple users on one computer
d. To provide a backup to cloud-based solutions during internet failures

A. For a software developer who is required to test an application in many environments

Explanation:
A client-side hypervisor is a type of hypervisor that runs directly on a client machine (such as a desktop or laptop) and allows multiple virtual machines (VMs) to run simultaneously. The best use case for a client-side hypervisor is for software developers who need to test their applications in various environments. With a client-side hypervisor, developers can create and manage multiple VMs, each with different operating systems and configurations, to simulate different testing environments efficiently. This allows developers to test their applications across different platforms, operating systems, and configurations without the need for multiple physical machines, saving time and resources.

A technician needs to install a cost-effective storage device into a rackmount server that will be used as a VM host. This storage will be used for all VMs that run from the server.

Which of the following should be used?
a. Optical disk drive
b. eMMC storage device
c. 15,000rpm drive
d. RAID 10 array

C. 15,000rpm drive

Explanation:
A 15,000rpm drive refers to a high-speed hard disk drive (HDD) commonly used in enterprise environments for high-performance storage. In scenarios where cost-effectiveness is a primary consideration and redundancy is not explicitly mentioned or required, opting for high-speed drives can provide good performance for VM hosting.

A technician installed new firmware on the company’s laser printers and has since been receiving multiple calls that information is garbled and looks like code. Only printers with the new firmware are having this issue.

Which of the following steps should the technician complete NEXT?
a. Change the language settings on the printers.
b. Reboot all the machines having the issues.
c. Reboot all the printers.
d. Install an updated printer driver on the print server.

D. Install an updated printer driver on the print server.

Explanation:
When only printers with the new firmware are experiencing garbled and code-like output, it suggests a compatibility issue between the new firmware and the existing printer drivers. By installing an updated printer driver on the print server, the technician can ensure compatibility between the firmware and the drivers, resolving the garbled output issue.

A user visits the help desk to report that a smartphone takes more than a day to fully charge. The user already tested multiple wall outlets and swapped the charging cable, but the results are the same.

Which of the following should the technician do FIRST?
a. Verify the power rating of the charger.
b. Ensure all unnecessary connectivity features are disabled.
