Question 1
Which configuration adds an IPv4 interface to an OSPFv3 process in OSPFv3 address family configuration?
- Router# ospf3 1 address-family ipv4
- Router(config-router)#ospfv3 1 ipv4 area 0
- Router(config-router)#ospfv3 3 1
- Router# ospfv3 1 address-family ipv4 unicast
Correct answer: B
Explanation:
The newest OSPFv3 configuration approach utilizes a single OSPFv3 process. It is capable of supporting IPv4 and IPv6 within a single OSPFv3 process. OSPFv3 builds a single database with LSAs that carry IPv4 and IPv6 information. The OSPF adjacencies are established separately for each address family. Settings that are specific to an address family (IPv4/IPv6) are configured inside that address family router configuration mode. Running single OSPFv3 for both IPv4 and IPv6 is supported since Cisco IOS Software Release 15.1(3)S. The new-style OSPFv3 process is enabled using the router ospfv3 process-number command. Within the OSPF process configuration mode, the OSPF process ID is defined (using the router-id ospf-process-ID command). OSPFv3 New-Style OSPF Configuration Commands:R1(config)#ipv6 unicast-routing //although only OSPFv3 for IPv4 is configured but we have to enable IPv6 under global configuration mode R1(config)#router ospfv3 1 R1(config-router)# router-id 1.1.1.1 R1(config)#interface GigabitEthernet0/1 R1(config-if)#ipv6 enable //although only OSPFv3 for IPv4 is configured but we have to enable IPv6 under interface mode R1(config-if)#ospfv3 1 ipv4 area 0 Therefore answer B is the best answer here but in this answer, the configuration mode is not correct. It should be interface mode (config-if)#, not router mode (config-router)#.

User in the branch network of 2001:db8:0:4 report they cannot access the internet.

- Issue the eigrp stub command on R1
- Issue the no neighbor stub command on R1
- Issue the eigrp stub command on R2
- Issue the no eigrp stub command on R2
Correct answer: B
Explanation:
In the output of R1, we see R1 has a default route to the Internet via G1/0, which is correct but R2 does not have this route. One reasonable answer of this issue is R1 has been configured as a stub router so it only advertised connected and summary routes. In Branch router output, we also see routes that are directly connected to R1 only. Note: In this topology, only Branch router should be configured as stub, not R1 router.

Question 3
An engineer configuration a static route on a router, but when the engineer checks the route to the destination, a different next hop is chosen.
What is the reason for this?
Router#show running-config | include ip route ip route 192.168.2.2 255.255.255.255 209.165.200.225 130 Router#show ip route
---output omitted---
Gateway of last resort is not set
192.168.1.0/32 is subnetted, 1 subnets
C 192.168.1.1 is directly connected, Loopback0
192.168.2.0/32 is subnetted, 1 subnets
O 192.168.2.2 [110/11] via 192.168.12.2,00:33:32, Ethernet0/0 192.168.12.0/24 is variably subnetted, 2 subnets, 2 masks C 192.168.12.0/24 is directly connected, Ethernet0/0 L 192.168.12.1/32 is directly connected, Ethernet0/0 209.165.200.0/24 is variably subnetted, 2 subnets, 2 masks C 209.165.200.0/24 is directly connected, Ethernet0/1 209.165.200.226/32 is directly connected, Ethernet0/1
- The configured AD for the static route is higher than the AD of OSPF
- The metric of the OSPF route is lower than the metric of the static route
- Dynamic routing protocol always have priority over static routes
- The syntax of the static route is not valid do the route is not considered
Correct answer: A
Explanation:
The AD of static route is manually configured to 130 which is higher than the AD of OSPF router which is 110. The AD of static route is manually configured to 130 which is higher than the AD of OSPF router which is 110.
