Q
  • 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
A

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.

L3
DRAM

A

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

A

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.

Q

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

A

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.)

Q
  • Which of the following is defined as the movement of electric charge?

Voltage
Wattage
Amperage
Impedance

A

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
A

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

A

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.

Replace the laptop battery
Reinstall the Operating System
Reset the docking station.
Remove and reseat the battery

A

Reset the docking station.

Explanation: You should first attempt reseating the laptop in the docking station; the laptop probably doesn’t have a sturdy connection, resulting in a blinking battery light telling you that the laptop is not charging properly (or at all).

Incorrect answers: Do this before you attempt to reseat or replace the battery. This is a hardware issue; the operating system does not have an effect on the blinking battery light.

Q
  • You are troubleshooting a coworker’s computer. When you ping the loopback address, you receive no response. Which of the following is the most likely cause of this problem?

The LAN is unresponsive.
The DHCP Server is down.
The Ethernet cable needs to be replaced.
The TCP/IP protocol is not functioning.

A

The TCP/IP protocol is not functioning.

Explanation: Pinging the loopback address should return results even if you are not physically connected to the network. This trick deals with the computer internally and doesn’t even need a LAN. You can ping the local computer with the commands ping loopback and ping localhost; however, the best option is to ping the actual IPv4 loopback IP address by typing ping 127.0.0.1 (or ping ::1 for IPv6). This removes any possible name resolution that might occur in Windows. Note that name resolution happens whenever you connect to a system by name (such as computerA, workstationB, and so on); the name must ultimately be translated to its corresponding IP address. So, to avoid any name resolution issues, we computer techs like to go right to the source and ping the IP address directly. This way, we can troubleshoot whether or not the TCP/IP protocol suite is functioning properly, without being concerned with any other services and name resolution getting in the way. It’s a good general practice for connecting to systems directly.

Incorrect answers: Pinging the loopback address doesn’t make use of the network, so the LAN, DHCP servers, and the Ethernet cable do not play into the scenario.

  • While troubleshooting a network problem, you discover that one set of LED lights on a Switch is blinking rapidly even when all other nodes are disconnected. Which of the following is the most likely cause of this problem? (Select the Two Best Answers)
Switch that is not plugged into a Server.
Defective hard drive in the computer.
Defective network card in the computer.
An unplugged Server
Defective port on the Network Switch
A

Defective network card in the computer.
Defective port on the Network Switch

Explanation: If only one computer is connected to the switch, there shouldn’t be much activity. Rapidly blinking LED lights might lead you to believe that the computer’s network card (NIC) or the port on the switch is faulty. The problem could be that the person is sending a lot of data to himself while you are testing the network, but that would be strange and rare.

Incorrect answers: Switches are not plugged into servers; however, they facilitate network connections between many computers. A defective hard drive would cause some kind of boot failure. The server doesn’t have anything to do with this scenario.

  • You are called to a school lab to fix a computer. The computer supposedly worked fine the day before, but now it does not power on. The computer is plugged into a power strip with another computer. The other computer works fine. Which of the following is the most likely cause of this problem? (Select the Two Best Answers)

The Power cable is unplugged from the computer.
The power strip is overloaded.
The monitor is unpluggged
The voltage switch on the power supply is set incorrectly
The power strip is unplugged

A

The power cable is unplugged from the computer.
The voltage switch on the power supply is set incorrectly

Explanation: Check the basics first! Make sure the power cable isn’t disconnected from the computer, and verify that the voltage switch on the power supply is in the correct position (if the PSU is not auto-switching). Kids like to play tricks on lab computers!

Incorrect answers: A standard power strip should not overload with just two computers connected to it, but if it does, press the reset switch on the power strip. The monitor being unplugged could be a separate problem, but it won’t prevent the computer from powering on. If the second computer works fine, that tells you the power strip is plugged in.

Incorrect answers: If the page file were on either of the other SATA drives, the constant accessing of the page file would slow down the OS performance or would slow down the access of user files. SATA hard drive 3 is a better option than the external USB flash drive for a variety of reasons: it is probably faster; it has less latency; and in general, internal drives perform more efficiently than external drives.

Q
  • A user reports that a laser printer is printing poorly. You observe that the pages have wrinkles and random patterns of missing print. Which of the following is the most likely cause of this problem?

The fuser needs replaced
The toner cartridge is defective
The corona wire is frayed
There is high humidity in the room

A

The fuser needs replaced

Explanation: The wrinkled pages are the number-one indicator that the fuser needs to be replaced. Random patterns of missing print further indicate that the fuser is not working properly. If you note that toner is not being fused to the paper, that is the last clue. The fuser usually needs to be replaced every 200,000 pages or so on a laser printer.

Incorrect answers: If the toner cartridge were defective, either you would get blank printouts or you would see lines or smears, but there wouldn’t be page wrinkles. If the transfer corona wire were defective, it might result in blank paper. Damage to the primary corona wire can also result in black lines or smearing. High humidity could cause the separation pads or rollers to fail.

Q
  • A computer has a RAID1 Array. SATA Drive 0 Failed, and now the computer will not boot. Which of the following steps would most likely fix the problem by allowing the computer to boot again?

Replace SATA Drive 1
Mark SATA Drive 1 as Active
Replace SATA Drive 0
Replace the Array’s Controller

A

Mark SATA Drive 1 as Active

Explanation: You would mark SATA Drive 1 as active. If you cannot access Disk Management, you would have to do it by booting the system with WinRE (System Recovery Options); accessing the Command Prompt; executing the diskpart command; and typing the commands select disk 1, select partition 1, and active. A RAID 1 array is a mirroring array with two drives. The second drive keeps an exact copy of the first drive in real time. If Drive 1 doesn’t take over automatically when Drive 0 fails, you will have to set it to active. Remember that a partition with an operating system must be set to active; otherwise, the computer will not be able to boot to the partition.

Incorrect answers: Replacing Drive 1 is not necessary because it did not fail. Replacing Drive 0 is inevitable if you want to re-create the mirror but not necessary if you just want to get the system to boot for now. Replacing the array’s controller is most likely not necessary. You should try replacing the drive first. It is possible (though unlikely) that the drive and the controller failed at the same time, but always start with the most likely culprit (and never change out more than one device at a time).

Q

Which of the following steps can be performed to ensure that all external traffic to your website is directed through a firewall to the right computer?

Configure Port Forwarding
List in the exceptions the IP Address of the local website
Configure NAT
Configure all interior traffic appropriately

A

Configure Port Forwarding

Explanation: In this scenario, your organization is running a web server on the LAN. Your job is to make sure that all clients outside your network on the Internet that are attempting to access the web server can do so. You must configure port forwarding for this to work. The HTTPS requests, or whatever port the clients use to access the web server (perhaps 443, but not necessarily), should be forwarded to the IP address and port of the web server on your network.

Incorrect answers: Exceptions are meant to allow certain computers access in or out of the firewall, but this would give the external clients too much access. You should streamline this configuration so that the external traffic is all directed to your web server, and port forwarding is the best way to do this. NAT, which stands for Network Address Translation, is used to match up the private IP address numbers of your internal computers to the external public IPs they attempt to connect to; it protects the private IP identity of the internal computers. However, it’s actually not the interior traffic you are concerned with. Instead, you are concerned with the external traffic trying to get into your network and visit your web server, and the web server only.

Q

You are troubleshooting an Internet Connectivity issue. Several laptop users cannot connect to any websites. Users with PCs do not have any trouble. Which of the following devices is most likely causing the problem?

Router
Cable Modem
WAP
Encryption Mismatch
Firewall
UTM
A

Firewall

Explanation: The wireless access point is most likely the problem. Perhaps it was turned off or disabled or lost its connection to the network. This WAP failure causes the laptops to fail when attempting to connect to websites, and furthermore, the laptops won’t have any Internet connection whatsoever. There are a lot of possibilities for why a client computer cannot connect to a WAP, but if several wireless clients cannot make the connection, you can usually assume that the problem is not at the client side and instead is at the central connecting device, in this case the WAP. Laptops often connect wirelessly because they are mobile devices, whereas PCs often connect in a wired fashion because they are stationary and don’t necessarily need a wireless connection.

Incorrect answers: If the PCs can connect to the Internet fine (as the question states), you can probably rule out the router, cable modem, firewall, and UTM device. That is, unless of course, one of the devices was configured with some kind of rule stating that the laptops can’t connect to websites. This is unlikely but is a possibility if the network has a firewall or UTM. UTM stands for unified threat management; UTM devices combine the functionality of firewalls, intrusion detection systems (IDS), and proxy servers, among other things. UTMs and next-generation firewalls (NGFWs) are designed to integrate a variety of threat defenses into one device. An encryption mismatch is always possible when it comes to wireless connections. Perhaps the WAP is configured for WPA2 and AES, but a laptop is configured with WPA or TKIP, or both. That mismatch would cause the laptop to fail to connect to the wireless network, and ultimately, the Internet. However, for several laptops to fail due to encryption mismatches, they would all have to be configured improperly, which again is unlikely, and at which point someone would be held accountable for the mistake. Don’t let this happen to you! Verify your configurations after you have made them; always test! Testing and troubleshooting are huge parts of the real IT world and the A+ exams, so be sure you study them and practice them intensely.
