To enable OSPFv3, 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
- Correct Answer
- Router1 (config - if) # ipv6 ospf 10 area 0.0.0.0
ExplanationTo enable OSPFv3, you enable the protocol at the interface level as with RIPng. The command string is ipv6 ospf proces-id area area-id.

- C. 32
- D. 128 Discuss
- 3. You are connecting an access point and it is set to root. What does extended service set ID mean?
Options- A. That you have more than one access point and they are in the same SSID connected by a distribution system
- B. That you have more than one access point and they are in seperate SSIDs connected by a distribution system
- C. That you have multiple access points, but they are placed physically in different buildings
- D. That you have multiple access points, but one is a repeater access point Discuss
- 4. Two workers have established wireless communication directly between their wireless laptops. What type of wireless topology has been created by these employees?
Options- A. BSS
- B. SSID
- C. IBSS
- D. ESS Discuss
- 5. A wireless client cannot connect to an 802.11b/g BSS with a b/g wireless card. The client section of the access point does not list any active WLAN clients. What is a possible reason for this?
Options- A. The incorrect channel is configured on the client
- B. The Client's IP address is on the wrong subnet
- C. The client has an incorrect pre-shared key
- D. The SSID is configured incorrectly on the client Discuss
- 6. 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

Options- A. FF02::A
- B. FF02::9
- C. FF02::5
- D. FF02::6 Discuss
- 8. What multicast addresses does RIPng use?
Options- A. FF02::A
- B. FF02::9
- C. FF02::5
- D. FF02::6 Discuss
- 9. 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
- 10. What does a link-local address always start with? Discuss

Correct Answer: Broadcasts have been eliminated and replaced with multicasts
Explanation:
There are no broadcasts with IPv6. Unicast , multicast, anycast, global, and link - local unicast are used.
Correct Answer: 16
Explanation:
There are 16 bits (four hex characters) in an IPv6 field.
Correct Answer: That you have more than one access point and they are in the same SSID connected by a distribution system
Explanation:
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.
Correct Answer: IBSS
Explanation:
Two wireless hosts directly connected wirelessly is no different then two hosts connecting with a crossover cable. They are both ad-hoc networks, but in wireless, we call this an independent Basic Service Set(IBSS).
Correct Answer: The SSID is configured incorrectly on the client
Explanation:
Although this question is cryptic at best, the only possible answer is option D. If the SSID is not being broadcast (which we must assume in this question), the client must be configured with the correct SSID in order to associate to the AP.
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: 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: 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: 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: FE80::/10
