More questions
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: An IP address on the physical interface
Explanation:
It is very important to remember when studying the CCNA exam objectives, and when configuring Frame Relay with point-to-point subinterfaces, that you do not put an IP address on the physical interface.
Correct Answer: debug ppp authentication
Explanation:
The command
debug ppp authentication will show you the authentication process that PPP uses between point-to-point connections.
Correct Answer: 11Mbps
Explanation:
The IEEE 802.11b standard provides a maximum data rate of up to 11Mbps.
Correct Answer: 1 and 4
Explanation:
Unlike full duplex, half-duplex Ethernet operates in a shared collision domain, and it has a lower effective throughput than full duplex.
Correct Answer: Outside global
Explanation:
The host on the global network after translation is considered to be an outside global host.
Correct Answer: A switch creates separate collision domains but one broadcast domain. A router provides a separate broadcast domain.
Explanation:
Switches break up collision domains, and routers break up broadcast domains.
Correct Answer: 1 and 4
Explanation:
An Ethernet frame has source and destination MAC addresses, an Ether-Type field to identify the Network layer protocol, the data, and the FCS field that holds the answer to the CRC.
Correct Answer: Add the source address and port to the MAC address table and forward the frame out the destination port
Explanation:
Since the source MAC address is not in the MAC address table, the switch will add the source address and the port it is connected to into the MAC address table and then forward the frame to the outgoing port.
Correct Answer: DSL
Explanation:
ATM is the Data-Link layer protocol that's typically used over the DSL layer 1 connection from the CPE and terminated at what's known as the DSLAM-an ATM switch that contains DSL interface cards, or ATU-Cs.
