Question 15

A network administrator is tasked with implementing a robust failover mechanism for internet connectivity. The organization utilizes two distinct ISP connections. The primary connection is established via GigabitEthernet1/0/1, and a secondary connection via GigabitEthernet1/0/2. Traffic originating from the internal network segment (192.168.10.0/24) must be directed towards the external network (203.0.113.0/24) preferentially through the primary link. In the event that the primary link fails to advertise routes for the external network, traffic should automatically transition to the secondary link. Which combination of Cisco IOS XE configurations accurately achieves this dynamic failover while ensuring policy-based routing for internal traffic?

Accepted Answer

Configure route-map `ROUTE-SELECTION` applied inbound on GigabitEthernet1/0/1 with a permit sequence for the external prefix-list and a lower metric, followed by a deny sequence for the same prefix-list. Configure route-map `POLICY-ROUTING` applied to the internal interface to match the internal prefix-list and set the next-hop to the primary gateway.

Question 16

A network administrator is configuring a Cisco IOS router and has learned about the 192.168.10.0/24 network via three distinct methods: a static route configured manually, an OSPF learned route with a calculated cost of 25, and an EIGRP learned route with a composite metric of 1500. Assuming default administrative distances are in effect, which route will the router install in its routing table for the 192.168.10.0/24 network, and why?

Accepted Answer

The static route, because it has the lowest administrative distance (1), making it the most trusted source.

Question 17

Anya, a network solutions specialist, is responsible for refining the Quality of Service (QoS) strategy within a growing enterprise network.
