IP SLA

An engineer configured IP SLA 20 to monitor the reachability of a next-hop router (192.168.1.1) using UDP jitter probes. The goal is to use the IP SLA with a track object to influence EIGRP route selection. However, the EIGRP route is not being affected by the IP SLA state. The engineer verifies that the IP SLA is 'Active' and the track object shows 'Up'. What is the most likely misconfiguration?

Question 4mediummultiple choice

A network engineer configured IP SLA 30 to monitor the reachability of a server (10.10.10.10) using ICMP echo probes. The IP SLA is linked to a track object that is used in a static default route. The engineer notices that the IP SLA state is 'Active', but the static route is not present in the routing table. The track object shows 'Up'. What should the engineer check first?

Question 5hardmultiple choice

An engineer configured IP SLA 40 with a UDP echo probe to monitor a remote server port 80. The IP SLA is used in a track object for a backup static route. The engineer observes that the IP SLA state is 'Timeout' even though the server is reachable via ping from the router. What is the most likely cause?

Question 6hardmultiple choice

A network engineer configured IP SLA 50 to monitor a remote router's loopback (5.5.5.5) using ICMP echo. The IP SLA is linked to a track object that is used in a PBR (policy-based routing) route-map. The engineer notices that the PBR is not applying the alternate path when the IP SLA goes down. The track object shows 'Down'. What is the most likely misconfiguration?

Question 7mediummultiple choice

An engineer configured IP SLA 60 to monitor the reachability of a WAN link's next-hop (203.0.113.1) using ICMP echo. The IP SLA is used in a track object for a floating static route. The engineer notices that the primary route (EIGRP) is present, but the floating static route is not installed when the primary fails. The track object shows 'Down' after the primary fails. What should the engineer check?

Question 8mediummultiple choice

A network engineer configured IP SLA 70 to monitor a remote site's LAN gateway (172.16.1.1) using ICMP echo. The IP SLA is linked to a track object that is used in a static route for a backup link.

Question 9hardmultiple choice

An engineer configured IP SLA 80 to monitor a remote server (192.168.100.100) using ICMP echo. The IP SLA is used in a track object for a static route. The engineer notices that the IP SLA state is 'Active', but the track object shows 'Down'. What is the most likely cause?

Question 10easymultiple choice

A network engineer configured IP SLA 90 to monitor a remote router's loopback (10.0.0.1) using ICMP echo. The IP SLA is linked to a track object that is used in a static route. The engineer notices that the IP SLA state is 'Active', but the static route is not installed. The track object shows 'Up'. The engineer checks the routing table and sees a different route to the same destination with a lower administrative distance. What should the engineer do to ensure the IP SLA-tracked route is used when the primary fails?
