Scott's excited that his new laptop has a Gigabit Ethernet (1000BaseT) capable NIC. However, when he plugs it into his network at the office, he only gets 100Mbit speeds. What's the problem? (A) His switch only supports 100BaseT (B) The other computers on the network only support 100BaseT (C) He needs to update the NIC's drivers (D) He needs to set the NIC's speed settings to "AUTO"

(A) His switch only supports 100BaseT His switch only supports 100BaseT. When two Ethernet devices connect, they negotiate in order to set themselves to the highest possible speed. In this case, the switch is 100BaseT. Incorrect answers: The drivers are fine. Your NIC's speed has nothing to do with the other computers. However, your actual data throughput will depend on the speed of the entire connection between the two communicating devices. Most NICs do have a property that defines the speed. In almost all cases this is set by default to "AUTO." There is a tiny chance that Scott's NIC is set to 100BaseT, but it's not nearly as common as the correct answer.

John's laptop won't recharge and he suspects the AC adapter is the problem. Which tool should he use to test it? (A) Multimeter (B) Power supply tester (C) Paper clip (D) Induction toner

(A) Multimeter Use a multimeter to test the AC adapter's output voltage. Incorrect answers reasons: An induction toner enables you to locate specific network cables, often inside a wiring closet. A power supply tester enables you to test a power supply when it's not plugged into a computer—a handy device, but not for testing an AC adapter. While you might be successful testing with a paper clip, it's probably not a good idea!

Mike's newly configured computer (using manual IP settings) can't access a Web site by its fully-qualified domain name (FQDN), but he can access it by the Web site's IP address. Everyone else on the network can access the site by the FQDN. Which of the following is the MOST likely problem? (A) The computer's DNS Client service is disabled (B) The computer's DNS settings are incorrect (C) The computer does not have DNS permissions enabled on the default gateway (D) The computer's DNS server is down

(B) The computer's DNS settings are incorrect Your DNS settings are incorrect. Given that most systems use DHCP, it's rare to have a problem like this, but if you typed in invalid manual DNS settings into your NIC's Properties, this can happen. Incorrect answers reasons: If you were to turn off the DNS Client service on your computer, you would get this problem. However, there is a much smaller chance that this service would be disabled than that someone had entered an invalid DNS service IP address. In a single network, everyone USUALLY uses the same DNS server, so if the DNS server is down for you, it's down for everyone else. Granted, you might have a different DNS server, so this answer is valid, but not as valid as entering an invalid DNS server IP address. Routers don't have an item in their Access Control Lists called "DNS permissions". You COULD block DNS from getting through your router by blocking port 53 (DNS), but then no one could get DNS access. Most routers have the ability to block a port number for a single IP or MAC address, but, again, it's simply too unlikely.

Bill returns from vacation, plugs in his laptop to charge, and preps for dinner. The dog bumps the table with the laptop and the laptop hits the floor. Bill checks for any obvious damage, such as a cracked screen, but sees nothing. He leaves the laptop on the charger over night and goes to work the next day. His laptop won't come up at all, even when it's plugged in. What's most likely the problem? (A) The fall damaged the power brick (B) The fall damaged the DC jack (C) The fall damaged the hard drive (D) The fall damaged the battery

(B) The fall damaged the DC jack The fall damaged the DC jack, rendering both the charging process and the plugged in failure. Incorrect answers reasons: The fall damaged the battery. This would have resulted in a very spectacular fire. The fall damaged the power brick. The laptop fell, not the power brick. The fall damaged the hard drive. In such a scenario, the computer would still have turned on, but would have been unable to access the OS.

A user describes a loud clicking noise coming from their system, and are unable to boot their computer to the operating system. The technician determines the loud clicking noise to be from the hard drive. What is MOST likely creating the noise? (A) Solid State read/write head scratching the platter surface (B) The motion of the read/write head armature parallel to the platter (C) Your system attempting to connect to the drive (D) Bad spindle motor bearings

(B) The motion of the read/write head armature parallel to the platter Traditional hard drives use platters that spin and use read/write heads on actuator arms to read the top and bottom of the platters. The arms are controlled by a servo motor. All these moving metal parts can wear down over time and break. Incorrect answers reasons: Your system uses electronic signal and no audible sound occurs. Solid state drives do not use moving parts. The hard drive does not have spindle motor bearings.

You are troubleshooting a laptop that was just recently diagnosed with trouble holding power. When you turn the laptop on to troubleshoot, you notice that even while connected to the AC power adapter, the laptop will still use battery power. What could be causing something like this to happen? (Choose two.) (A) The battery is incompatible with the laptop (B) The power adapter that plugs into the wall is malfunctioning (C) You have selected a power scheme in your OS that disables charging (D) The LCD's power inverter is malfunctioning (E) The internal power circuity on the motherboard is faulty

(B) The power adapter that plugs into the wall is malfunctioning (E) The internal power circuity on the motherboard is faulty The internal power circuity and the power adapter are the two pieces to this mystery that need to be checked out. Either one could be at fault, or worse... both! Incorrect answers reasons: If the LCD's power inverter was malfunctionng, we would have a working laptop, we just wouldn't see anything on the laptop's screen. There is no power scheme in your OS that will disable battery charging. The battery being incompatible with system is unlikely. Laptops always come with a battery when purchased. Batteries are also very proprietary to the unit they are meant for.

Your new office networked printer is having trouble. You set the IP address to 192.168.4.3. It self-tests just fine and everything is properly configured, but no one can print to it. When you try to PING the printer, you don't get a response. All computers can access the server and the Internet—you even PING the router at 192.168.41.1 and it responds nicely. What should you now suspect? (A) The subnet mask for the entire network (B) The printer's IP address (C) The network switch (D) The printer's NIC

(B) The printer's IP address The printer's IP address looks like it is not in the same network as the rest of the PCs—certainly worth checking next! Incorrect answers reasons: The network switch is not the problem if you can still access the server and Internet. The printer's NIC is probably not the issue if it can self-test okay. The network's subnet mask is not the issue if the server and Internet can be accessed.

Martha's inkjet printer's output has the bottom of every letter missing in text and strange horizontal lines evenly spaced in her images. What part of the inkjet should she check for problems? (A) The paper take-up rollers (B) The printhead (C) The photosensitive drum (D) The printer's resolution

(B) The printhead Missing lines of horizontal print always points to a problem with the printhead. Incorrect answers reasons: The paper is being printed on, so it's not the take-up rollers. Inkjet printers do not have photosensitive drums. The printer resolution is not at fault, either.

You are installing a new video card in a PC. What is the most reliable place to get the most up-to-date driver? (A) The installation disc that came with your new video card (B) the manufacture's Web site (C) The Windows driver library on the OS installation disc (D) The default PnP driver

(B) the manufacture's Web site The best place to find the most up-to-date driver is the manufacturer's Web site. Incorrect answers reasons: Drivers may change after the card is made and shipped, so the installation disc is a no-go. Windows has a good library of drivers, but they will not be as up-to-date as the manufacturer's latest drivers. Any default driver is just a very basic driver designed for the lowest common denominator; such a driver will never be the most-up-to date.

How many devices can you attach to a single serial ATA controller? (A) 2 (B) 64 (C) 1 (D) 8

(C) 1 Only one drive device can connect to a single SATA controller. Incorrect answers reasons: The other answers just aren't true, and are incorrect.
