Which TCP/IP protocol is used to provide shared access to files and printers on the network?
- FTP
- SSH
- SMB
- SNMP
Correct Answer

A. SMB

You have just installed a new HP LaserJet printer on your network. You've plugged it directly into a CAT6a network cable. You try to install the printer on a client using the printer's IP address, but you are unable to connect. The printer is in Ready state. What should you do next?
- Double-check the printer's IP configuration information.
- Stop and restart the spooler service.
- Take the printer offline and bring it back online.
- Turn the printer off and back on to save the IP configuration information.
Correct Answer

A. Double-check the printer's IP configuration information.

Explanation

For network-enabled laser printers, no connectivity can be a sign of improperly configured IP settings such as the IP address. While each printer is somewhat different, you can manually configure most laser printers’ IP settings through the LCD control panel.

You are troubleshooting a computer with a RAID-10 array using four disks. One of the disks fails. What can you do to recover the array?
- Replace the failed disk and restore from backup.
- Remove the failed disk and rebuild the array.
- Rebuild the failed disk and restore from backup
- Replace the failed disk and rebuild the array.
Correct Answer

A. Replace the failed disk and rebuild the array.

Explanation

RAID-10 is a mirrored striped set. As long as one drive in each mirrored pair is functional (just as in RAID-1), you shouldn't lose any data. Simply replace the failed disk and rebuild the array.

One of your friends complains that when he plays action games on his computer, the screen is slow to refresh and the motion is often jerky. What should he do to resolve this problem?
- Buy a newer monitor.
- Increase system RAM.
- Increase video memory.
- Lower the screen resolution.
Correct Answer

A. Increase video memory.

Explanation

Certain unacceptable video-quality issues (such as jerky refresh speeds or lags) can be remedied by adding memory to a video card. Doing so generally results in an increase in both quality and performance. If you can't add memory to the video card, you can upgrade to a new one.

Which Wi-Fi encryption standard was the first to include the use of a 128-bit dynamic per-packet encryption key?
- WEP
- WPA
- WPA2
- AES
Correct Answer

A. WPA

Explanation

Wi-Fi Protected Access (WPA) was the first Wi-Fi encryption standard to implement the use of the Temporal Key Integrity Protocol (TKIP). Whereas WEP used a static 40- or 128-bit key, TKIP uses a 128-bit dynamic per-packet key. It generates a new key for each packet sent.

Which TCP/IP protocol, designed to download email, allows for multiple clients to be simultaneously connected to the same mailbox?
- SMTP
- POP3
- IMAP
- SMB
Correct Answer

A. IMAP

Explanation

Internet Message Access Protocol (IMAP) is a secure protocol designed to download email. It has several advantages over the older Post Office Protocol 3 (POP3). First, IMAP4 works in connected and disconnected modes. Second, it lets you store the email on the server, as opposed to POP3, which requires you to download it. Third, IMAP4 allows multiple clients to be simultaneously connected to the same inbox.

You have a user who needs recommendations for installing a home server PC. She wants her family to be able to share files and videos on their home network. She also wants her data to be protected in the event of a hard drive failure. Which two components do you recommend she include?
- Dedicated print server
- RAID array
- Gigabit NIC
- Dual processors
Correct Answer(s)

A. RAID array
A. Gigabit NIC

Explanation

A home server PC should be able to handle media streaming as well as file and printer sharing. A dedicated print server is not likely needed, though, as the operating system can function as a print server. A gigabit NIC will be helpful to manage the network traffic, and a RAID array can help protect against hard drive failure.

You are configuring hosts on a network running IPv4. Which elements are required for the computer to connect to the network?
- IP address
- IP address and subnet mask
- IP address, subnet mask, and default gateway
- IP address, subnet mask, default gateway, and DNS server address
Correct Answer

A. IP address and subnet mask

Explanation

To communicate on an IPv4 network, a host must be configured with a valid IP address and a subnet mask. A default gateway is needed only if the host will connect to a remote network. DNS servers are optional but useful, because they resolve hostnames to IP addresses.

Which of the following wireless communication methods are the least susceptible to hacking? (Choose two.)
- Wi-Fi
- IR
- Bluetooth
- NFC
Correct Answer(s)

- Multicast
- Anycast
- Unicast
- Broadcast
Correct Answer

A. Multicast

Explanation

There are three types of addresses in IPv6: unicast, anycast, and multicast. A unicast address identifies a single node on the network. An anycast address refers to one that has been assigned to multiple nodes. A multicast address is one used by multiple hosts. IPv6 does not use broadcasts.

Which TCP/IP host-to-host protocol makes its best effort to deliver data but does not guarantee it?
- IP
- TCP
- UDP
- ICMP
Correct Answer

A. UDP

Explanation

The two host-to-host protocols are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). TCP guarantees packet delivery through the use of a virtual circuit and data acknowledgments, and UDP does not. Because of this, TCP is often referred to as connection oriented, whereas UDP is connectionless.

- None of the cards will function.
- The cards will all operate at the faster speed.
- The cards will all operate at the slower speed.
Correct Answer

A. The cards will all operate at the slower speed.

You have reason to believe that several network users are actively browsing prohibited content on unsecured sites on the Internet. Which port can you disable on the firewall to immediately stop access to these websites?
- 53
- 67
- 80
- 443
Correct Answer

A. 80

Explanation

Normal (unsecured) websites are accessed on port 80, which is the port that Hypertext Transfer Protocol (HTTP) uses. Shut it down, and no one will be able to access websites, except secure sites that use HTTPS, which is on port 443.

Rate this question:

The AES security algorithm was introduced with which Wi-Fi encryption standard?
- WEP
- WPA
- WPA2
- TKIP
Correct Answer

A. WPA2

Explanation

Wi-Fi Protected Access 2 (WPA2) is a huge improvement over WEP and WPA. It uses Counter Mode CBC-MAC Protocol (CCMP), which is a protocol based on the Advanced Encryption Standard (AES) security algorithm. CCMP-AES was created to address the shortcomings of TKIP, so consequently it's much stronger than TKIP.

You are troubleshooting a laptop with an integrated wireless networking card. The user reports that the laptop will not connect to the Internet. When you look at the network card, the connection and activity lights alternate blinking, in a steady pattern. What is the most likely cause of the problem?
- No network connection
- Incorrect TCP/IP configuration
- Failed network card
- Unable to reach a DNS server
Correct Answer

A. No network connection

Explanation

Some wireless cards will have their connection and activity lights alternatively blink if there is no network connection. If the card had failed, there likely would be no lights on it at all.
