Topic 1 · Question 425

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?

AIt starts sending traffic without a specific matching entry in the routing table to GigabitEthernet0/1.
BIt immediately replaces the existing OSPF route in the routing table with the newly configured static route.
CIt starts load-balancing traffic between the two default routes.
DIt ignores the new static route until the existing OSPF default route is removed. (correct answer)

Reveal answer & explanation

Correct answer: D

The correct answer is D. Option D: It ignores the new static route until the existing OSPF default route is removed.

Explanation

A static route is manually configured and does not adapt automatically to topology changes. A default route matches destinations not covered by a more-specific route. OSPF is a link-state IGP that uses cost and a shortest-path calculation to select routes.

Topic 1 · Question 433

Which action does the router take as it forwards a packet through the network?

AThe router encapsulates the original packet and then includes a tag that identifies the source router MAC address and transmits it transparently to the destination.
BThe router encapsulates the source and destination IP addresses with the sending router IP address as the source and the neighbor IP address as the destination.
CThe router replaces the original source and destination MAC addresses with the sending router MAC address as the source and neighbor MAC address as the destination. (correct answer)
DThe router replaces the source and destination labels with the sending router interface label as a source and the next hop router label as a destination.

Reveal answer & explanation

Correct answer: C

The correct answer is C. Option C: The router replaces the original source and destination MAC addresses with the sending router MAC address as the source and neighbor MAC address as the destination.

Explanation

OSPF elects a designated router on multiaccess networks to reduce adjacency and LSA exchange overhead. NAT translates addresses between network domains, commonly conserving public IPv4 addresses.

The correct answer is A. Option A: It provides the default gateway redundancy on a LAN using two or more routers.

Explanation

A host sends traffic for remote IP networks to its configured default gateway.
