| Question ID 14542 | Which statements are TRUE regarding Internet Protocol version 6 (IPv6) addresses?
(Choose three.)
|
| Option A | An IPv6 address is divided into eight 16-bit groups.
|
| Option B | A double colon (::) can only be used once in a single IPv6 address.
|
| Option C | IPv6 addresses are 196 bits in length.
|
| Option D | Leading zeros cannot be omitted in an IPv6 address.
|
| Option E | Groups with a value of 0 can be represented with a single 0 in IPv6 address.
|
| Correct Answer | A,B,E |
Explanation Explanation: IPv6 addresses are divided into eight 16-bit groups, a double colon (::) can only be used once in an IPv6 address, and groups with a value of 0 can be represented with a single 0 in an IPv6 address. The following statements are also true regarding IPv6 address: IPv6 addresses are 128 bits in length. Eight 16-bit groups are divided by a colon (:). Multiple groups of 16-bit 0s can be represented with double colon (::). Double colons (::) represent only 0s. Leading zeros can be omitted in an IPv6 address. The option stating that IPv6 addresses are 196 bits in length is incorrect. IPv6 addresses are 128 bits in length. The option stating that leading zeros cannot be omitted in an IPv6 address is incorrect. Leading zeros can be omitted in an IPv6 address.
| Question ID 14543 | Scenario
Refer to the topology. Your company has decided to connect the main office with three
other remote branch offices using point-to-point serial links.
You are required to troubleshoot and resolve OSPF neighbor adjacency issues between
the main office and the routers located in the remote branch offices.
An OSPF neighbor adjacency is not formed between R3 in the main office and R6 in the
Branch3 office. What is causing the problem?
|
| Option A | There is an area ID mismatch.
|
| Option B | There is a PPP authentication issue; the username is not configured on R3 and R6.
|
| Option C | There is an OSPF hello and dead interval mismatch.
|
| Option D | The R3 router ID is configured on R6.
|
| Option F | Answer : D
Explanation: Using the show running-config command we see that R6 has been incorrectly configured with the same router ID as R3 under the router OSPF process.
|
| Correct Answer | D |
