- Which of the following multimeter settings should be used only when there is no electrical flow through the part being tested? (Select the Two Best Answers)
Continuity Wattage Voltage Amps Resistance
Continuity
Resistance
Explanation: Of the listed answers, continuity and resistance are the settings that you should use when there is no electrical flow through the part being tested, and you want to be sure that there is no electrical flow when doing these tests. Examples of continuity or resistance tests include testing a fuse’s impedance (measured in ohms) and testing a network cable for continuity. In each example, you don’t want any electricity flowing through the device or line. It would give erratic results and could possibly cause damage to your testing equipment and even you.
Incorrect answers: When testing for watts, volts, and amps, you need to have electricity flowing through the item you want to test.

- Which type of cache memory is shared by all cores of a CPU?
L1
L2
L3
DRAM
L3
Explanation: L3 cache is shared by all of the cores of the CPU.
Incorrect answers: L1 cache is built into the CPU. L2 cache is built onto the CPU; it is also known as on-die. DRAM is the memory modules you install into the slots in the motherboard. DRAM is not cache memory. Some people consider DRAM to be L4 cache, but there is an actual CPU cache known as L4 used by Xeon and other high-end processors.

- Which technology calculates two independent sets of instructions simultaneously, simulating two CPUs?
Hyper-Threading
HyperTransport
Turbo Boost
Multi-Core
Hyper-Threading
Explanation: Hyper-threading (for example, Intel HT) calculates two independent sets of instructions simultaneously, simulating two CPUs.
Incorrect answers: HyperTransport is a high-speed link between various devices such as the CPU and northbridge on AMD systems. Turbo Boost is a basic form of overclocking that Intel allows with many of its processors. Multi-core is the technology in which a CPU physically contains two or more processor cores. Many CPU designs combine multi-core technology with hyper-threading to allow for even more processing.

You think that the power supply in your PC might be failing, causing issues with a SATA drive. You decide to test the SATA drive. Which of the following are the standard voltages of a SATA connection on an ATX power supply?
3.3V, 5V, 12V
-3.3V, 5V, -12V
-5V, 5V, 12V
5V and 12V
3.3V, 5V, 12V
Explanation: SATA power connections have 3.3, 5, and 12 volt wires.
Incorrect answers: There are no negative voltage wires on SATA power connections. Molex power connections use 5 V and 12 V only, but SATA includes the 3.3 volt line. In this scenario, you should test the SATA power connector and the main power connector from the power supply with your trusty PSU tester. (Most PSU testers have an SATA power port in addition to the main 24-pin power port.)

- Which of the following is defined as the movement of electric charge?
Voltage
Wattage
Amperage
Impedance
Amperage
Explanation: Amperage can be defined as electric current or the movement of electric charge. It is measured in amps (A). You should know your circuits in your office. The more you know, the less chance of overloading them. For example, a standard 15 amp circuit might be able to handle three or four computers and monitors. But a 20 amp circuit can handle a computer or two more than that. Circuit breakers, electrical cable, and outlets all must comply with a certain number of amps. If you connect a power strip or surge protector, make sure that it is specified to work with your circuit’s amp rating.
Incorrect answers: Voltage is a representation of potential energy, measured in volts (V). Wattage is electric power, the rate of electric energy in a circuit, measured in watts (W). Impedance is the amount of resistance to electricity, measured in ohms (Ω).

- Which of the following protocols can be used to configure and monitor network printer device status?
SMTP SNMP TCP/IP IPP DNS
SNMP
Explanation: The Simple Network Management Protocol (SNMP) can be used to monitor remote computers and printers. This requires the installation of SNMP on the appropriate hosts.
Incorrect answers: SMTP is the Simple Mail Transfer Protocol, which deals with the sending of email. TCP/IP is the entire suite of protocols that you use when you connect to an IP network. IPP is the Internet Printing Protocol, which allows hosts to print documents to a remote printer without the need for UNC paths. DNS is the Domain Name System, which resolves domain names to their corresponding IP addresses.

- In a RAID5 Array of eight hard drives, how many can fail without losing an entire array?
Zero
One
Two
Five
One
Explanation: One hard drive can fail in a RAID 5 array, and the array can rebuild that drive’s data from the remaining drives. However, if a second drive fails, the array is toast. The reason is that the array requires the parity information from all the other drives.
Incorrect answers: If you had a RAID 6 array (which includes another parity stripe), you could lose as many as two drives and still continue to function. Regardless, be sure to have a backup plan in place.
