Q

User Datagram Protocol (UDP) is a connection-oriented protocol that requires a set of initial steps in order to establish connection (three-way handshake), supports retransmission of lost packets, flow control (managing the amount of data that is being sent), and sequencing (rearranging packets that arrived out of order).

2.4 GHz frequency band
5.0 GHz frequency band
Maximum data signaling rate of 600 Mbps
Carrier Sense Multiple Access / Collision Avoidance (CSMA/CA) network access method
17
Q

Which of the following answers refers(s) to the feature(s) of the IEEE 802.11ac wireless standard amendment?

A

5.0 GHz frequency band
Carrier Sense Multiple Access / Collision Avoidance (CSMA/CA) network access method
Multi-User Multiple Input / Multiple Output (MU-MIMO)

18
Q

Which of the wireless security standards listed below has been deprecated in favor of newer standards due to known vulnerabilities resulting from implementation flaws?

A

WEP

19
Q

Which of the following wireless encryption schemes offers the highest level of protection?

A

WPA2

20
Q

A security protocol introduced in order to strengthen existing WEP implementations without requiring the replacement of legacy hardware is known as:

A

TKIP

21
Q

AES-based encryption mode is a characteristic feature of:

A

WPA2

22
Q

A portion of the available Radio Frequency (RF) band allocated for wireless communication is known as:

A

Channel

23
Q

A situation in which multiple channels share the frequency band causing interference and performance degradation for devices operating on channels that are too close to each other is known as:

A

Channel overlapping

24
Q

A common example of channel overlapping in wireless networking would be the 2.4 GHz band used in 802.11, 802.11b, 802.11g, and 802.11n networks, where the 2.401 - 2.473 GHz frequency range is used for allocating 11 channels, each taking up a 22-MHz portion of the available spectrum. Setting up a wireless network to operate on a non-overlapping channel (1, 6, and 11 in this case) allows multiple networks to coexist in the same area without causing interference.

A

True

25
Q

A server with private IP address has been set up to handle requests from an outside (public) network. Which of the solutions listed below would enable its function?

A

Port forwarding
