Question 1
Question
An engineer wants to set the OSPFv3 router ID for router R1. Which of the following answers could affect R1’s choice of OSPFv3 router ID?
Answer
-
The ipv6 address command on interface Gigabit0/0
-
The ip address command on interface Serial0/0/1
-
The <b>ospf router-id</b> command in OSPFv3 configuration mode
-
The ipv6 address command on interface loopback2
Question 2
Question
Router R1 has a Serial0/0/0 interface with address 2001:1:1:1::1/64, and a G0/0 interface with address 2001:2:2:2::1/64. The OSPFv3 process uses process ID 1. Which of the following OSPFv3 configuration commands enable OSPFv3 on R1’s G0/0 interface and places it into area 0?
Answer
-
A network 2001:1:1:1::/64 1 area 0 command in router configuration mode
-
An ipv6 ospf 1 area 0 command in G0/0 interface configuration mode
-
A network 2001:1:1:1::/64 1 area 1 command in router configuration mode
-
An ospf 1 area 0 command in G0/0 interface configuration mode
Question 3
Question
An enterprise uses a dual-stack model of deployment for IPv4 and IPv6, using OSPF as the routing protocol for both. Router R1 has IPv4 and IPv6 addresses on its G0/0 and S0/0/0 interfaces only, with OSPFv2 and OSPFv3 enabled on both interfaces for area 0 and the router ID explicitly set for both protocols. Comparing the OSPFv2 and OSPFv3 configuration, which of the following statements is true?
Answer
-
The OSPFv3 configuration, but not OSPFv2, uses the router-id router-id router subcommand.
-
Both protocols use the router-id router-idrouter subcommand
-
Both protocols use the network network-number wildcard areaarea-id router subcommand.
-
The both protocols use the ipv6 ospf process-id areaarea-id interface subcommand.
Question 4
Question
R1 and R2 are routers that connect to the same VLAN. Which of the answers lists an item that can prevent the two routers from becoming OSPFv3 neighbors? (Choose three answers .)
Answer
-
Mismatched Hello timers
-
Mismatched process IDs
-
IPv6 addresses in different subnets
-
Equal router IDs
-
One passive router interface (used on this link)
Question 5
Question
The example shows an excerpt from the show ipv6 route ospfcommand on a router (R1). Which of the answers are correct about the interpretation of the meaning of the output of this command? (Choose two answers.)
R1# show ipv6 route ospf
--OI 2001:DB8:1:4::/64 [110/129]
--------via FE80::FF:FE00:1, Serial0/0/1
Answer
-
110 is the metric for the route.
-
S0/0/1 is an interface on R1.
-
FE80::FF:FE00:1 is a link-local address on R1.
-
OI means that the route is an interarea OSPF route.
Question 6
Question
Router R1 has been configured as a dual-stack IPv4/IPv6 router, using interfaces S0/0/0, S0/0/1, and GigabitEthernet0/1. As a new engineer hired at the company, you do not know whether any of the interfaces are passive. Which of the following commands lets you find whether G0/1 is passive, either by the command listing that fact or by that command leaving passive interfaces out of its list of interfaces ?
Answer
-
show ipv6 ospf interface brief
-
show ipv6 protocols
-
show ipv6 ospf interface G0/1
-
show ipv6 ospf interface passive
