Question 6 of 619

Refer to the exhibit. An engineer configures 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?

Dynamic routing protocols always have priority over static routes.

The metric of the OSPF route is lower than the metric of the static route.

The configured AD for the static route is higher than the AD of OSPF.

The syntax of the static route is not valid, so the route is not considered.

Correct Answer: C

The Administrative Distance (AD) is a measure of the trustworthiness of the source of the routing information. The lower the AD, the more preferred the route. In this scenario, the static route has been configured with an AD of 130, while the OSPF protocol, which is dynamically configured, has an AD of 110. Since 110 is lower than 130, the OSPF route is preferred over the static route. This is why the different next hop is chosen.

Question 7 of 619

Refer to the exhibit. An engineer is trying to generate a summary route in OSPF for network 10.0.0.0/8, but the summary route does not show up in the routing table.

Why is the summary route missing?

The summary-address command is used only for summarizing prefixes between areas.

The summary route is visible only in the OSPF database, not in the routing table.

There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.

The summary route is not visible on this router, but it is visible on other OSPF routers in the same area.

Correct Answer: C

The summary route is not appearing in the routing table because there are no specific routes within the 10.0.0.0/8 network present in the routing table. OSPF generates a summary route only when there are more specific routes within the summarized range. Since there are no routes for any subnets inside 10.0.0.0/8 in the routing table, the summary route is not generated.

Question 8 of 619

Refer to the exhibit. An engineer is trying to block the route to 192.168.2.2 from the routing table by using the configuration that is shown. The route is still present in the routing table as an OSPF route.

Which action blocks the route?

Use an extended access list instead of a standard access list.

Change sequence 10 in the route-map command from permit to deny.

Use a prefix list instead of an access list in the route map.

Add this statement to the route map: route-map RM-OSPF-DL deny 20.

Correct Answer: B

To block the route to 192.168.2.2, it is necessary to change the sequence 10 in the route-map command from permit to deny. The current configuration permits the route as it matches the specified access list and permits the route map sequence. By changing the sequence to deny, any route matching the access list (in this case, 192.168.2.2) will be denied, effectively blocking it from the routing table.

Question 9 of 619

What is a prerequisite for configuring BFD?

Jumbo frame support must be configured on the router that is using BFD.

All routers in the path between two BFD endpoints must have BFD enabled.

Cisco Express Forwarding must be enabled on all participating BFD endpoints.

To use BFD with BGP, the timers 3 9 command must first be configured in the BGP routing process.

Correct Answer: C

Cisco Express Forwarding (CEF) must be enabled on all participating BFD endpoints. CEF is a high-speed packet forwarding mechanism that BFD relies on to quickly detect link failures. Without CEF, BFD packets would have to be handled by the CPU, which could slow down the detection of failures. Hence, enabling CEF ensures efficient operation of BFD.
