- B. By the far end router
- C. By the clock rate command
- D. By the Physical layer bits stream timing Discuss

Correct Answer: The last four digits are the used at the access layer to identify a particular telephone The next three numbers are used at the distribution layer to identify an exchange that services several phone numbers The area code is used at the core level for routing between different regions
Correct Answer: FF02:0000:0000:0000:0000:0000:130F:0005
Correct Answer: DSL
Explanation:
ATM is the Data-Link layer protocol that's typically used over the DSL layer1 connection from the CPE and terminated at what's known as the DSLAM - an ATM switch that contains DSL interface cards, or ATU-Cs.
Correct Answer: PPP
Explanation:
PPP is your only option because 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: Supplied by the CSU/DSU
Explanation:
Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your non-production test environment, then you need to supply clocking with the clock rate command on the serial interface of the router with the DCE cable attached.
Correct Answer: Using multiple protocols is modular and allows changes to one protocol without affecting the others For example, if the addressing protocol is dependent on the delivery protocol, changes to one would imply changes need to be made to the other
Correct Answer: Routing moves a letter or telephone call to the access layer (as in a street or telephone exchange) Switching makes the final delivery A switching decision is made on the part of the address that is not used in routing (as in the street number or last four digits of a phone number)
Correct Answer: Classless routing protocols advertise subnet mask information along with the network prefixes Classful routing protocols do not Therefore, for a classful protocol, all subnets for the major network number being used must be the same length Also, classful protocol cannot support discontiguous networks prefixes
Correct Answer: OSPF intra-area and interarea routes, and possibly a default route External routes from ABRs are blocked, and external routes from ASBRs are converted to N1 or N2 routes
Correct Answer: OSPF intra-area and interarea routes, and a default route External routes are not advertised into a stub area
