- Question
Suppose you have a customer who has a central HQ and six branch offices. The customer anticipates adding six more branches in the near future. It whishes to implement a WAN technology that will allow the branches to economically connect to HQ and you have no free ports on the HQ router. which of the following would you recommend?
Options- A. PPP
- B. HDLC
- C. Frame Relay
- D. ISDN
- Correct Answer
- Frame Relay
ExplanationThe 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.
- 1. What does a link-local address always start with? Discuss
- 2. Which of the following is true when describing a multicast address?
Options- A. Packets addressed to a multicast address are delivered to a single interface
- B. packets are delivered to all interfaces identified with the address. This is also called a one-to-many address
- C. A multicast address identifies multiple interfaces and is delivered to only one address. This address can also be called one-to-one-of-many
- D. These addresses are meant for nonrouting purposes,but they are almost globally unique, so it is unlikely they will have an address overlap Discuss
- 3. What multicast addresses does RIPng use?
Options- A. FF02::A
- B. FF02::9
- C. FF02::5
- D. FF02::6 Discuss
- 4. What multicast addresses does EIGRPv6 use?
Options- A. FF02::A
- B. FF02::9
- C. FF02::5
- D. FF02::6 Discuss
- 5. To enable RIPng , which of the following would you use?
Options- A. Router1 (config - if) # ipv6 ospf 10 area 0.0.0.0
- B. Router1 (config - if) # ipv6 router rip 1
- C. Router1 (config - if) # ipv6 router eigrp 10
- D. Router1 (config - if) # ospf ipv6 10 area 0 Discuss
- 6. When a router is connected to a Frame Relay WAN link using a serial DTE interface, how is the clock rate determined?
Options- A. Supplied by the CSU/DSU
- B. By the far end router
- C. By the clock rate command
- D. By the Physical layer bits stream timing Discuss
- 7. The Acme Corporation is implementing dail-up services to enable remote-office employees to connect to the local network. The company uses multiple routed protocols,needs authentication of users connecting to the network, and since some calls will be long distance, needs callback support. Which of the following protocols is the best choice for these remote services?
Options- A. 802.1
- B. Frame Relay
- C. HDLC
- D. PPP Discuss
- 8. Which of the following uses ATM as the Data Link layer protocol that's terminated at what's known as the DSLAM?
Options- A. DSL
- B. PPPoE
- C. Frame Relay
- D. Dedicated T1 Discuss
- 9. What is the full IPv6 address represented by FF02::130F:5? Discuss
- 10. What are the access, distribution, and core components of a North American phone number? Discuss

Correct Answer: FE80::/10
Correct Answer: packets are delivered to all interfaces identified with the address. This is also called a one-to-many address
Explanation:
Packets addressed to a multicast address are delivered to all interfaces identified with the multicast address, the same as in IPv4. It is also called a one-to-many address. You can always tell a multicast address in IPv6 because multicast addresses always start with FF.
Correct Answer: FF02::9
Explanation:
RIPng uses the multicast IPv6 address of FF02::9. If you remember the multicast addresses for IPv4, the numbers at the end of each IPv6 address are the same.
Correct Answer: FF02::A
Explanation:
EIGRPv6's multicast address stayed very near the same. In IPv4 it was 224.0.0.10; now it is FF02::A (A = 10 in decimal notation)
Correct Answer: Router1 (config - if) # ipv6 router rip 1
Explanation:
It's pretty simple to enable RIPng for IPv6. You configure it right on the interface where you want RIP to run with the ipv6 router rip number command.
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: 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: 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: FF02:0000:0000:0000:0000:0000:130F:0005
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
