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?

1. A. Optical disk drive
2. B. eMMC storage device
3. C. 15,000rpm drive
4. D. RAID 10 array

Correct Answer: D
RAID 10 array is often used for server virtualization as it provides both redundancy and performance benefits. It uses a combination of mirroring and striping to provide both fault tolerance and improved I/O performance. An optical disk drive or eMMC storage device would not provide enough storage or performance for a VM host server, while a 15,000rpm drive may provide good performance but would not provide redundancy for fault tolerance. Therefore, a RAID 10 array is the best option for cost-effective storage that will be used for all VMs that run from the server.

A department sends in a ticket to report a printer is not working. The responding technician sees paper stuck to the fuser, which is much hotter than normal. The (user was just installed a few weeks ago. as indicated by the service history. Which of the following should the technician do NEXT?

1. A. Disconnect the printer power for troubleshooting.
2. B. Install a printer roller kit.
3. C. Replace the overheating fuser.
4. D. Replace the paper with thicker paper stock.

Correct Answer: A
The first step in troubleshooting a printer issue is to disconnect the printer power to avoid electric shock or further damage to the printer. The technician can then inspect the fuser and determine if it needs to be replaced or repaired. Installing a printer roller kit or replacing the paper with thicker paper stock will not solve the problem of the overheating fuser. Replacing the fuser without disconnecting the power is dangerous and not recommended. References: https://www.comptia.org/certifications/a#examdetails https://www.comptia.org/blog/what-is-a-fuser

1. A. RJ45
2. B. Straight tip
3. C. DB9
4. D. Molex

Correct Answer: D
The connector that the IT technician should inspect further is Molex. The Molex connector is used to provide power to the motherboard and other components in the computer.

A user with a self-configured, static IP address cannot connect to the internet. The technician runs an ipconfig command and receives the following output:

Which of the following should the technician edit?

1. A. IPv4 address
2. B. Subnet mask
3. C. DHCP server
4. D. Default gateway

Correct Answer: D
The correct answer is D. Default gateway.
A default gateway is the device that connects a local network to other networks, such as the internet. A default gateway is usually a router or a modem that has an IP address on the same subnet as the local network. A default gateway is necessary for a device to communicate with devices outside its local network.
In this case, the user has a self-configured, static IP address of 192.168.1.20, which belongs to the subnet 192.168.1.0/24 (with a subnet mask of 255.255.255.0). However, the default gateway is set to 192.168.0.1, which belongs to a different subnet (192.168.0.0/24). This means that the user’s device cannot reach the default gateway, and therefore cannot connect to the internet.
The technician should edit the default gateway to match the correct subnet of the user’s device, such as 192.168.1.1 or 192.168.1.254, depending on the configuration of the network.
