IP SLA

A network engineer configures an IP SLA on a Cisco router to monitor reachability to a critical server at 10.1.1.1 using ICMP echo. The IP SLA is used as a track object for a static default route. After deployment, the engineer notices that the static route is never removed from the routing table, even when the server is unreachable. The IP SLA operation shows 'State: Active' and 'Latest RTT: NoConnection/Busy/Timeout'. What is the most likely cause?

Question 3hardmultiple choice

An engineer configures IP SLA 100 to monitor the jitter and latency of a VoIP call path between two branch routers. The configuration uses UDP jitter with a target of 192.168.2.2 on port 16384. The engineer notices that the IP SLA operation shows 'State: Active' but no jitter or latency statistics are collected. The router is generating the probe packets, but the remote router does not respond. What is the most likely reason?

Question 4mediummultiple choice

A network engineer configures IP SLA 1 to monitor HTTP server availability at 10.1.1.1 using HTTP GET. The operation is used as a track object for a backup static route. The engineer notices that the IP SLA operation shows 'State: Active' and 'Latest RTT: 200 ms', but the track object shows 'Track 1: up' even though the HTTP server returns a 404 error. What is the cause?

An engineer configures IP SLA 10 to monitor the reachability of a next-hop router at 10.1.1.1 using ICMP echo. The IP SLA is used as a track object for a static route. The engineer notices that the IP SLA operation shows 'State: Active' and 'Latest RTT: 1 ms', but the track object shows 'Track 10: up' even though the next-hop router is actually unreachable from the source. The source router has a default route pointing to 10.1.1.1. What is the most likely cause?

Question 6mediummultiple choice

A network engineer configures IP SLA 20 to monitor the response time of a DNS server at 10.1.1.1 using DNS query for 'example.com'. The operation is used to influence routing decisions.
