- Question
A default Frame Relay WAN is classified as what type of physical network?
Options- A. Point-to-point
- B. Broadcast multi-access
- C. Non-broadcast multi-access
- D. Non-broadcast multipoint
- Correct Answer
- Non-broadcast multi-access
ExplanationFrame Relay, by default, is a non-broadcast multi-access (NBMA) network, which means that broadcasts, such as RIP updates, will not be forwarded across the link by default. - 1. What is the maximum distance running the lowest data rate for 802.11a?

Correct Answer: About 175 feet
Explanation:
The IEEE 802.11a standard's lowest data rate is 6Mbps, but it can run from a distance of about 175 feet.
Correct Answer: About 65-75 feet
Explanation:
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.
Correct Answer: About 300 feet
Explanation:
The IEEE 802.11g standard's lowest data rate is 6Mbps, but it can run from a distance of about 300 feet.
Correct Answer: 54Mbps
Explanation:
The IEEE 802.11a standard provides a maximum data rate of up to 54Mbps.
Correct Answer: AWPP
Explanation:
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.
Correct Answer: Frame Relay
Explanation:
The key is "there are no free ports" on your router. Only Frame Relay can provide a connection to multiple locations with one interface, and in an economical manner no less.
Correct Answer: PPP
Explanation:
PPP is your only option, as HDLC and Frame Relay do not support these types of business requirements. PPP provides dynamic addressing, authentication using PAP or CHAP, and callback services.
Correct Answer: 3, 4 and 5
Explanation:
Ethernet and Token Ring are LAN technologies and cannot be configured on a serial interface. PPP, HDLC, and Frame Relay are layer 2 WAN technologies that are typically configured on a serial interface.
Correct Answer: 1 and 2
Explanation:
Please do not freak out because ATM is an answer to this question. ATM is not covered in depth on the CCNA exam. PPP is mostly used for dial-up (async) services, but ATM could be used as well, though it typically is not used anymore since PPP is so efficient.
Correct Answer: Dedicated T1
Explanation:
In a modern network, hybrid fibre-coaxial (HFC) is a telecommunications industry term for a network that incorporates both optical fiber and coaxial cable to create a broadband network.
