Correct Answer:

Multimode fiber - The distance exceeds the maximum length of each of these copper solutions.

Incorrect Answers:

CAT 5e, CAT 6, and coaxial would require multiple repeater stations along the way to reach that distance.

Correct Answer:

Layer 1, or the Physical layer, defines how the data will be sent over the network. It does this by converting the ones and zeros in the packets into the type of pulses needed for the cable, such as electrical pulses for copper cable, or light pulses for fiber-optic cable.

Incorrect Answers:

None of the other layers does this function.

Correct Answer:

War driving is a form of leeching. It's where someone jumps on your wireless connection without your knowledge. In the instance of war driving, they are usually in a moving vehicle. If you adjust your signal strength enough to only reach the inside of your building, you won't have to worry about war drivers.

Incorrect Answers:

Changing your SSID means that the person who is war driving will have to choose a different network name to attach to.

Changing the frequency (if that's even possible with the WAP in question) wouldn't help because then none of your wireless devices would be able to communicate with the WAP.

Changing the channel is completely transparent to the users connecting to a WAP.

Correct Answer:

Signal strength - Reducing the signal strength of the WAP will reduce interference on the neighboring network.

Incorrect Answers:

WEP keys, MAC filtering, and WPA encryption configurations cannot cause or cure signal interference.

Correct Answer:

Heating, ventilation, and air conditioning (HVAC) governs the environmental temperature on and around the rack.

Incorrect Answers:

High-authority atmospheric control, high-volume atmospheric control, and high voltage alternating current are all made-up terms.

Correct Answer:

nbtstat - This command checks NetBIOS status and information

Incorrect Answers:

netstat shows connections to and from the local machine.  

arp checks IPs against MAC addresses.  

nslookup performs DNS lookups.

Correct Answer:

MT-RJ - The way I remember this one is that the MT-RJ supposedly resembles the RJ-45. The MT-RJ is one of four fiber-optic cable connectors, including the ST, SC, and LC.

Incorrect Answers:

RJ-11 is for phone lines and CAT 3 Ethernet, RS-232 is for printer ports, and BNC is for ThinNet cables.

Correct Answer:

The server is missing default gateway information.

- This is a critical configuration element that is necessary if traffic is to go beyond the local network.

Incorrect Answers:

It's possible that there's an incorrect subnet mask, but there is a more likely answer.  

There is nothing that leads us to believe that a routing loop has occurred.  

If the connection from the switch to the gateway was using the wrong type of cord, Indira would not be able to ping it at all.

Correct Answer:

Certificate services - Public Key Infrastructure (PKI) is a methodology for using various pieces to manage and distribute certificates.

Incorrect Answers:

Router commands, ACLs, and a RADIUS server do not use PKI to perform their functions.

Correct Answer:

Mitigation means lessening the force or intensity of something unpleasant. In other words, we don’t want security threats. How do we make them go away? We train our users to be smart!

Incorrect Answers:

Allowing unauthorized devices on the LAN could be a major security risk.

Letting the clients update their own virus definitions could be a train wreck. Ask your mom or dad the last time they manually updated their virus definitions.

Using PAP is not so much a great idea. Password Authentication Protocol (PAP) sends its passwords in clear text.
