IP SLA →hardMultiple ChoiceObjective-mapped

Quick Answer

The answer is that EIGRP does not support direct tracking of IP SLA for route metrics, so the track object must be applied to a static route or redistribution policy rather than to EIGRP itself. The core technical concept is that IP SLA tracking operates at the interface or static route level, not within EIGRP’s dynamic routing process; EIGRP selects routes based on its composite metric and neighbor reachability, not on the state of a track object. On the Cisco CCNP ENARSI 300-410 exam, this tests your understanding of how IP SLA and EIGRP interact—a common trap is assuming that a track object tied to an IP SLA will automatically influence EIGRP’s routing table, but in reality, you must use a tracked static route as a floating default or manipulate redistribution to affect EIGRP’s decision. The search intent “IP SLA not affecting EIGRP” often arises when engineers forget that EIGRP ignores track objects natively. Memory tip: “EIGRP tracks neighbors, not SLA probes—static or redistribute to make it notice.”

300-410 IP SLA Practice Question

This 300-410 practice question tests your understanding of ip sla. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

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?

A
The IP SLA probe type (UDP jitter) is not supported for tracking EIGRP routes.
Why wrong: UDP jitter is supported for IP SLA; the probe type is not the issue.
B
The track object is not configured to influence the EIGRP route; EIGRP does not support direct tracking of IP SLA for route metrics.
EIGRP does not have a mechanism to directly track IP SLA states. The engineer must use a tracked static route or policy-based routing to influence traffic.
C
The EIGRP route has a higher administrative distance than the tracked route.
Why wrong: Administrative distance is not related to IP SLA tracking; the route is still present but not affected by the track state.
D
The IP SLA threshold is set too low, causing flapping.
Why wrong: The track object shows 'Up', so the threshold is not causing flapping.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The track object is not configured to influence the EIGRP route; EIGRP does not support direct tracking of IP SLA for route metrics.

EIGRP does not natively react to IP SLA track objects unless the route is redistributed or a static route with tracking is used. The engineer likely expected EIGRP to automatically adjust metric based on IP SLA, which is not supported.

Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

✗
The IP SLA probe type (UDP jitter) is not supported for tracking EIGRP routes.
Why it's wrong here
UDP jitter is supported for IP SLA; the probe type is not the issue.
✓
The track object is not configured to influence the EIGRP route; EIGRP does not support direct tracking of IP SLA for route metrics.
Why this is correct
EIGRP does not have a mechanism to directly track IP SLA states. The engineer must use a tracked static route or policy-based routing to influence traffic.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
The EIGRP route has a higher administrative distance than the tracked route.
Why it's wrong here
Administrative distance is not related to IP SLA tracking; the route is still present but not affected by the track state.
✗
The IP SLA threshold is set too low, causing flapping.
Why it's wrong here
The track object shows 'Up', so the threshold is not causing flapping.

Common exam traps

Common exam trap: NAT rules depend on direction and matching traffic

NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.

Trap categories for this question

Command / output trap
The track object shows 'Up', so the threshold is not causing flapping.

Detailed technical explanation

How to think about this question

NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.

KKey Concepts to Remember

Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.

TExam Day Tips

Identify inside and outside interfaces first.
Check whether the scenario needs static NAT, dynamic NAT or PAT.
Do not confuse NAT matching ACLs with normal packet-filtering intent.

Key takeaway

NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Real-world example

How this comes up in practice

A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.

What to study next

Got this wrong? Here's your next step.
