A co-worker at a satellite office reports that a new replacement shared work group printer has arrived. It is the same model as the old one. Your co-worker replaced the old printer and connected all the cables to the new printer. Which of the following is the easiest way to ensure that all the client computers can connect to the printer via ipp?
A) name the new printer with the old printer name
B) allow the printer to acquire a DHCP address
C) in dhcp, set a reservation by Mac address
D) have your co-worker print the configuration page
In dhcp, set a reservation by Mac address
In this scenario, the clients are most likely connecting to the printer using the IP address. Internet printing protocol can be used in this manner. By default, the moment the new printer is connected to the network, it acquires an IP address from the DHCP server, this is a new IP address that is different from the one used by the old printer. This causes the clients to fail when attempting to connect and print to the new printer. To prevent this problem, you can go to the router for another DHCP device and configure a MAC address reservation.
Which of the following protocols can be used to configure and monitor network printer device status?
A) SMTP
B) SNMP
C) TCP/IP
D) IPP
E) DNS
SNMP - simple Network management protocol can be used to monitor remote computers and printers. This requires the installation of SNMP on the appropriate hosts. Be sure to use the latest version of SNMP across all devices.
Which of the following symptoms would indicate a power supply issue?
A) the CPU is overclocking
B) the Wi-Fi range is reduced
C) the storage drives fail frequently
D) USB drives are not recognized by Windows
The storage drives fail frequently
An indication of a power supply issue is frequent failure of storage drives. If the power supply fails to provide clean power to the 3.3, 5, 12v lines to the drives, those drives will fail frequently. These are often the first devices to fail when a power supply starts having intermittent problems. You should test such issues with a power supply tester or multimeter
You are building a new gaming PC and want to select a motherboard that supports the scalable link interface SLI technology so you can install two SLI video cards connected by a bridge. Which of the following expansion slots should the motherboard have for your two video cards?

A) RAID 0
B) RAID 1
C) RAID 5
D) RAID 10
RAID 5
Raid 5 is Fault tolerant and allows for striping with parity if you have at least three drives to dedicate to the array. It is the parody information that makes it fault tolerant
A customer wants you to daisy chain 3 monitors. When purchasing the monitors, which of the following video types should you make sure is available?
