Wireless Technologies(Networking ) Questions and answers for exam Preparation

Question 1. What is the frequency range of the IEEE 802.11a standard?

2.4Gbps
5Gbps
2.4GHz
5GHz

Explanation:-

Answer: Option D. -> 5GHz
The IEEE 802.11a standard runs in the 5GHz RF range.

Question 2. You have a Cisco mesh network. What protocol allows multiple APs to connect with many redundant connections between nodes?

LWAPP
AWPP
STP
IEEE

Explanation:-

Answer: Option B. -> AWPP
Each AP in a mesh network runs the Adaptive Wireless Path Protocol (AWPP). This protocol allows RAPs to communicate with each other to determine the best path back to the wired network via the RAP.

Question 3. What is the frequency range of the IEEE 802.11b standard?

2.4Gbps
5Gbps
2.4GHz
5GHz

Explanation:-

Answer: Option C. -> 2.4GHz
The IEEE 802.11b and IEEE 802.11g standards both run in the 2.4GHz RF range.

Question 4. What is the maximum distance with maximum data rate for 802.11a?

About 65-75 feet
About 90-100 feet
About 150 feet
Over 200 feet

Explanation:-

Answer: Option A. -> About 65-75 feet
The IEEE 802.11a standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 65 to 75 feet.

Question 5. What is the maximum distance running the lowest data rate for 802.11b?

About 100 feet
About 175 feet
About 300 feet
About 350 feet

Explanation:-

Answer: Option D. -> About 350 feet
The IEEE 802.11b standard provides the lowest data rate at 1Mbps, but it also has the longest distance, which is about 350 feet.

Question 6. What is the maximum distance running the lowest data rate for 802.11a?

About 100 feet
About 175 feet
About 300 feet
About 350 feet

Explanation:-

Answer: Option B. -> About 175 feet
The IEEE 802.11a standard's lowest data rate is 6Mbps, but it can run from a distance of about 175 feet.

Question 7. What is the maximum distance with maximum data rate for 802.11g?

About 65-75 feet
About 90-100 feet
About 150 feet
Over 200 feet

Explanation:-

Answer: Option B. -> About 90-100 feet
The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 90 to 100 feet.

Question 8. You are connecting your access point and it is set to root. What does Extended Service Set ID mean?

That you have more than one access point and they are in the same SSID connected by a distribution system.
That you have more than one access point and they are in separate SSIDs connected by a distribution system.
That you have multiple access points, but they are placed physically in different buildings.
That you have multiple access points, but one is a repeater access point.

Explanation:-

Answer: Option A. -> That you have more than one access point and they are in the same SSID connected by a distribution system.
Extended Service Set ID means that you have more than one access point and they all are set to the same SSID and all are connected together in the same VLAN or distribution system so users can roam.

Question 9. How many non-overlapping channels are available with 802.11h?

3
12
23
40

Explanation:-

Answer: Option C. -> 23
The IEEE 802.11h standard provides an addition 11 channels to the 802.11a standard's 12 non-overlapping channel for a total of 23 non-overlapping channels.

Question 10. Cisco's Unified Wireless Solution provides a mesh solution. What devices do you absolutely need to purchase to run a Cisco solution?
1. WCS
2. Controller
3. Access point
4. Bridge

1 and 2
2 and 3
1 and 4 only
4 only

Explanation:-

Answer: Option B. -> 2 and 3
The Cisco Unified Wireless Solution is a great product, but you must purchase specialized devices. Cisco managed access points and a controller are the devices you need to purchase to run the Unified Wireless Solution.
