Actual exam question from Cisco's 300-410

Question #: 483
Topic #: 1

Refer to the exhibit.

An engineer observes that every time the ICMP packet is lost at a polling interval, track 1 goes down, which causes unnecessary disruption and instability in the network. The engineer does not want the traffic to be rerouted if the loss of ICMP packets is negligible. If the packet loss is persistent for a longer duration, the track must go down and the traffic must be rerouted. Which action resolves the issue?

A. Change the IP SLA schedule to run only at certain intervals.
B. Increase the timeout value from 1000 to 1500.
C. Define a delay timer under track 1.
D. Increase the threshold value from 1000 to 1500.

C seems vorrect, but delay should be configured under "the ip sla 1" and not under the track object. More info: https://packetpushers.net/blog/using-ip-sla-delay-feature-to-safely-monitor-lossy-links/ So C seems correct, but the answer is not correctly written.

Selected Answer: D

IP SLA parameters: threshold – specifies after how much time a “reaction event” takes place, such as considering a particular SLA as “down.” In simpler terms, for an icmp-echo SLA, it is the amount of time that must pass without a successful ping before the SLA is considered down. timeout – the amount of time an IP SLA will wait for a response from its echo request packet. -> Therefore we must increase the “threshold” parameter, not “timeout”.

Selected Answer: C

Correct, a delay timer configured under the IP SLA will give leniency so that track 1 won't go down if packet loss is small enough.
