B. CPU

C. RAM

D. Power supply

E. Power cord

Answer

A

D. Power supply

The most likely culprit is the power supply. It’s possible but highly unlikely that the motherboard, CPU, or RAM could be causing the issue. It’s definitely not the power cord, because the system is getting power.

Question 11

Q

You support an old impact printer at work. When the printer prints, the text is always goes from darker to lighter as it moves across the page. What is the most likely cause of the problem?

A. The print ribbon is old and needs to be replaced.

B. The print ribbon is not advancing properly.

C. The printhead needs to be replaced.

D. The wrong printer driver is installed.

Answer

A

B. The print ribbon is not advancing properly.

If an impact printer outputs dark to light across a page, that means that the printer ribbon is not advancing properly; the gear likely needs to be replaced. If the output were consistently faded, then you would replace the ribbon.

Question 12

Q

A smartphone user calls to report that she cannot decrypt encrypted emails, but other email seems to be fine. What is the most likely cause of this problem?

A. Corrupted email client software

B. GPS not functioning

C. Incorrect username or password

D. Improper S/MIME configuration

Answer

A

D. Improper S/MIME configuration

If a user can’t decrypt email, it is most likely because S/MIME settings are not properly enabled on the email account, which means installing the certificate (and by extension, a private key) on the mobile device. It could be that the email client software got corrupt, but that’s unlikely because other email works. The username and password are correct because the user is receiving other email. GPS has nothing to do with email.

Question 16

Q

You have been using your laser printer for just over five months. Recently, you noticed that the printed characters on the left side of your documents are faint compared to the letters on the right. How can you quickly resolve this problem?

A. Print your documents backward

B. Use different paper

C. Shake the toner cartridge

D. Blow the excess dust out of the cartridge

Answer

A

C. Shake the toner cartridge

Most documents have more characters printed on the left side of the paper than on the right side. Therefore, the toner from the left side of the cartridge runs out sooner, and the print on the left side of the documents will be faint. Shaking the toner cartridge redistributes the toner evenly on both sides.

Question 17

SMTP is for sending email to an email server. The IMAP and POP3 protocols can be used to retrieve email from mail servers. FTP is for file transfers.

Question 20

Q

After printing documents, the toner smears on the output pages whenever you touch it. Otherwise, things appear to be working properly. What is the most likely cause of the problem?

A. The printer driver is faulty.

B. The fuser is not heating properly.

C. There is toner on the transfer corona wire.

D. There is a scratch on the EP drum.

Answer

A

B. The fuser is not heating properly.

If the fuser does not heat properly, toner will not bond to the paper, and you will have smearing. White streaks on printouts are most likely caused by toner on the transfer corona wire. Vertical black lines are caused by a scratch or a groove in the EP drum. Faulty printer drivers will cause garbage to print, or there will be no printing at all.

Question 33

Q

You have recently installed a DHCP server on your network, and you notice that network performance has slowed down considerably. When monitoring the network traffic, you see excessive amounts of DHCP packets. What should you do to resolve this issue?

A. Decrease the DHCP lease time

B. Increase the DHCP lease time

C. Install a DHCP relay agent

D. Uninstall the DHCP server

Answer

A

B. Increase the DHCP lease time

DHCP clients broadcast to get an IP address from the server. When their lease is close to expiration, they will broadcast again to renew the lease. Increasing the lease time will resolve this issue. Uninstalling the DHCP server would too, but that also eliminates the benefit of using DHCP.

Question 34

Q

Your network has two subnets separated by a router. To make network administration easier, you install a DHCP server on subnet A. Clients on subnet B are not getting IP addresses automatically. What is the best way to resolve this?

A. Install a DHCP relay agent on subnet A

B. Install a DHCP relay agent on subnet B

C. Install a second DHCP server on subnet B

D. Configure the router to forward broadcast messages

Answer

A

B. Install a DHCP relay agent on subnet B

DHCP requests are made via broadcast and will not travel through the router. It’s never a good idea to allow routers to forward broadcasts. You could install a second DHCP server, but that’s inefficient. Install a DHCP relay agent on subnet B.

Q

Which cloud term refers to the process by which a provider charges for resources used?

A. Rapid elasticity

B. On-demand self-service

C. Resource pooling

D. Measured service

Answer

A

D. Measured service

Providers typically measure the amount of resources used by clients and charge them for what has been used. This is called a measured service, and it functions much like utilities. The ability to quickly expand services is called rapid elasticity. On-demand self-service means that clients can get new resources without supplier intervention. Resource pooling is taking resources from multiple machines and making them available as one pool.

A. A reservation

B. A Lightweight Directory Access Protocol

C. A Network Address Translation

D. A Common Internet File System

Answer

A

A. A reservation

On the DHCP server, you can specify that certain hosts will always receive the same IP address, which is called a reservation. Lightweight Directory Access Protocol (LDAP) is a protocol designed to speed up an administrator’s organization of and access to critical network directories. LDAP uses port 389. Network Address Translation (NAT) is a service that translates private, non-routable IP addresses into public addresses that can be used on the Internet. The Common Internet File System (CIFS) is TCP/IP protocol that uses port 445. It is used to share files and printers between computers, regardless of the operating system that they run.

A. Worn paper-feed rollers

B. Faulty stepper motor

C. Faulty fuser assembly

D. EP drum not advancing properly

Answer

A

A. Worn paper-feed rollers

Of the causes listed, the most likely cause is a worn paper-feed roller. Stepper motors control the back-and-forth motion of a print head in an inkjet printer. If the fuser assembly were faulty, the images would smear. If the EP drum doesn’t advance properly, multiple parts of the image will appear on top of each other.

Question 52

Q

A computer you are troubleshooting can’t get on the Internet or access local resources. You run ipconfig, and the system has an IP address of 169.254.18.36 and a subnet mask of 255.255.0.0. Computers on the network get their IP configuration information from a DHCP server. What appears to be the issue?

A. The computer has an incorrect subnet mask.

B. The network card is failing.

C. The client cannot reach the DHCP server.

D. There is an IP address conflict.

Answer

A

C. The client cannot reach the DHCP server.

If a DHCP client can’t access a DHCP server, it will autoconfigure with an APIPA address. Any address starting with 169.254.x.x is an APIPA address. Such systems will not be able to get on the Internet or access local resources, unless those resources somehow have an APIPA address as well.

A

B. Prevent overages in the subscriber’s data plan

The use of the cellular data network counts against the subscriber’s monthly data plan. Disabling the cellular data connection does not change how calls are processed or presented. Updates will not occur over the cellular network when cellular data is disabled but can still occur over Wi-Fi.

Question 58

Q

What is the lowest grade of cable required to run 100BaseT?

A. UTP CAT-3

B. UTP CAT-5

C. UTP CAT-5e

D. Multimode fiber

Answer

A

B. UTP CAT-5

In order to run 100BaseT, you need CAT-5 or better. The T in 1000BaseT indicates twisted-pair cable, not fiber-optic cable.

Question 59

Q

You want to ensure that a certain data stream receives guaranteed bandwidth. What level of QoS should you specify in the SLA?

A. 0

B. 1

C. 5

D. 6

Answer

A

C. 5

In the Quality of Service (QoS) service-level agreement (SLA), you should specify level 5. Higher numbers indicate higher levels of service, but the highest level anyone can configure is 5. Levels 6 and 7 are reserved for control data.

Question 60

Q

You have blocked port 110 on your firewall. Based on this action, which of the following may be true?

A. Clients on your network will not be able to access web pages.

B. Clients on your network will not be able to send email.

C. Clients on your network will not be able to retrieve email unless their email client supports POP3.

D. Clients on your network will not be able to retrieve email unless their email client supports IMAP.

Answer

A

D. Clients on your network will not be able to retrieve email unless their email client supports IMAP.

Port 110 is used for POP3, which is an email-retrieval protocol. Client computers with email software that supports IMAP may still be able to download email.

Question 61

Q

Your laptop has 8 GB of installed memory and uses shared video memory. If the video card is using 1 GB, how much is left for the rest of the system?

A. 1 GB

B. 7 GB

C. 8 GB

D. 9 GB

Answer

A

B. 7 GB

If the laptop is using shared video memory, then the system memory is shared with the video card. If the video card is using 1 GB, and the system has 8 GB total, then 7 GB is left for the system.

Question 62

Q

Which of the following is true for computers configured with APIPA?

A. They will be able to communicate with other APIPA-configured computers on their local network.

B. They will not be able to communicate with other APIPA-configured computers on their local network.

C. They will be able to communicate with any computer on their local network.

D. They will not be able to communicate with any computer on their local network.

Answer

A

A. They will be able to communicate with other APIPA-configured computers on their local network.

Computers configured with APIPA will have an IP address in the 169.254.0.0 range with a subnet mask of 255.255.0.0. They will be able to communicate with other computers on the local network that have the same network address. They will not be able to get on the Internet.

Question 63

Q

Every time you turn on a laptop computer, you need to re-enter the correct time and date. What is the most likely cause of the problem?

A. Failed CMOS battery

B. Corrupted BIOS

C. Failed motherboard

D. Incorrect POST settings

Answer

A

A. Failed CMOS battery

Whenever a system fails to hold the time and date when it’s powered off, the most likely culprit is the CMOS battery. It’s a lot like a watch battery and is usually easy to replace. Simply replace it, and the system should work normally.

Question 64

Q

You have been given a new toolkit for troubleshooting computer problems. In it is a device marked “loopback.” What is the function of a loopback plug?

A. It tests a telephone line.

B. It terminates a SCSI cable.

C. It tests the functionality of a NIC.

D. It measures the signal strength of an Ethernet cable.

Answer

A

C. It tests the functionality of a NIC.

Loopback plugs take the signal going out on the transmit path and connects it back to the receive path. This allows you to test certain legacy ports as well as Ethernet NICs to make certain they are working correctly.

Answer 65

A

A. Enable MAC filtering

Enabling MAC filtering allows only specific computers to use the wireless router. Disabling an SSID broadcast makes it so the router doesn’t broadcast its name, which can make it seem “invisible” to a casual snoop. It’s not a reliable security procedure, though. Changing the SSID from the default is always a good idea. You should use some sort of wireless security, but WPA is more secure than WEP.

Answer 66

A

D. Dead pixels

Dead pixels occur when certain points on the screen will not light up. The only solution is to replace the display unit. Burn-in and artifacts are when other, dim images show up on the computer along with the intended image. Distorted images look pulled or stretched. Faulty video drivers do not cause burn-in, artifacts, distorted images, or dead pixels.

Answer 67

A

A. Baseband OS

All wireless communications are handled by the baseband system in the phone, sometimes referred to as the radio or the modem. The baseband OS manages the baseband system and communicates to the phone’s primary OS. The SIM OS manages data transfers between the smartphone and the SIM memory chip. There is no NFC OS. iOS and Android OS do not manage wireless communications.

Answer 68

A

A. Print a test page from the user’s computer

Printing a test page is the best place to start. If that does not work, you may want to delete and reinstall the printer. Printing a test page using the printer’s self-test will only tell you if the printer is printing fine, not if that one user is having a problem. Always use the test page feature from the printer properties, not from an application, to test printing.

Answer 69

A

B. Question the user and identify user changes to the computer

C. Inquire regarding environmental changes

The three sub-steps to identify the problem are: question the user and identify user changes to computer, inquire regarding environmental or infrastructure changes, and review system and application logs. In this case, since the system will not power on, system and application logs are unavailable. Conducting internal or external research is part of establishing a theory of probable cause.
