B. ipv6 route::/0 Serial 0/0/1
C. ipv6 route:0/0 Serial 0/0/0
D. ip route 0.0.0.0 0.0.0.0 Serial 0/0/0
E. ipv6 route::/0 2000::2

Refer to the exhibit. Which command configures a floating static route to provide a backup to the primary link?

A. ip route 209.165.200.224 255.255.255.224 209.165.202.129 254
B. ip route 209.165.201.0 255.255.255.224 209.165.202.130
C. ip route 0.0.0.0 0.0.0.0 209.165.200.224
D. ip route 0.0.0.0 0.0.0.0 209.165.202.131

Correct Answer: A

Cisco Certified Network Associate (200-301 CCNA) – Question427

Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem? (Choose two.)


A. All of the routers need to be configured for backbone Area 1.
B. R1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3.
C. A static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established.
D. The hello and dead interval timers are not set to the same values on R1 and R3.
E. EIGRP is also configured on these routers with a lower administrative distance.
F. R1 and R3 are configured in different areas.

Correct Answer: DF

Explanation:

Explanation:
This question is to examine the conditions for OSPF to create neighborhood. So as to make the two routers become neighbors, each router must be matched with the following items:
1. The area ID and its types
2. Hello and failure time interval timer
3. OSPF Password (Optional)

Refer to the exhibit. If configuring a static default route on the router with the ip route 0.0.0.0 0.0.0.0 10.13.0.1 120 command, how does the router respond?

A. It starts sending traffic without a specific matching entry in the routing table to GigabitEthernet0/1.
B. It immediately replaces the existing OSPF route in the routing table with the newly configured static route.
C. It starts load-balancing traffic between the two default routes.
D. It ignores the new static route until the existing OSPF default route is removed.

Correct Answer: D

Explanation:

Explanation:
Our new static default route has the Administrative Distance (AD) of 120, which is bigger than the AD of OSPF External route (O*E2) so it will not be pushed into the routing table until the current OSPF External route is removed.
For your information, if you don’t type the AD of 120 (using the command “ip route 0.0.0.0 0.0.0.0 10.13.0.1”) then the new static default route would replace the OSPF default route as the default AD of static route is 1.
You will see such line in the routing table:
S* 0.0.0.0/0 [1/0] via 10.13.0.1

Refer to the exhibit. Which route does R1 select for traffic that is destined to 192.168.16.2?

A. 192.168.16.0/21
B. 192.168.16.0/24
C. 192.168.16.0/26
D. 192.168.16.0/27

Correct Answer: D

Explanation:

Explanation:
The destination IP addresses match all four entries in the routing table but the 192.168.16.0/27 has the longest prefix so it will be chosen. This is called the “longest prefix match” rule.

Cisco Certified Network Associate (200-301 CCNA) – Question423

A router running EIGRP has learned the same route from two different paths. Which parameter does the router use to select the best path?

A. as-path
B. administrative distance
C. metric
D. cost

Correct Answer: D

Explanation:

Explanation:
If a router learns two different paths for the same network from the same routing protocol, it has to decide which route is better and will be placed in the routing table. Metric is the measure used to decide which route is better (lower number is better). Each routing protocol uses its own metric.
For example, RIP uses hop counts as a metric, while OSPF uses cost.

Refer to the exhibit. The New York router is configured with static routes pointing to the Atlanta and Washington sites.
Which two tasks must be performed so that the Se0/0/0 interfaces on the Atlanta and Washington routers reach one another? (Choose two.)

A. Configure the ipv6 route 2023::/126 2012::1 command on the Atlanta router.
B. Configure the ipv6 route 2012::/126 2023::2 command on the Washington router.
