SNMP and Syslog →mediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is that the router will send SNMP traps to 192.168.1.100 using the community string 'public' for linkdown and linkup events. This is correct because the `snmp-server enable traps snmp linkdown linkup` command activates trap generation for those specific interface state changes, while the `snmp-server host` command directs those traps to the Network Management Station (NMS) at 192.168.1.100 using SNMPv2c and the specified community string. The `snmp-server community public RO` line defines the community used for trap transmission, not for trap reception—a common point of confusion. On the ENCOR 350-401 exam, this tests your understanding of the distinction between read-only (RO) and read-write (RW) community strings versus the trap community, and how the `enable traps` command must match the event types you want to monitor. A key memory tip: the trap community string on the `snmp-server host` line must match a community defined on the router, but it does not need to be the RW community—it only needs to be a valid string that the NMS will recognize.

350-401 SNMP and Syslog Practice Question

This 350-401 practice question tests your understanding of snmp and syslog. 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.

Given the following SNMP configuration on a Cisco IOS-XE router:

snmp-server community public RO
snmp-server community private RW
snmp-server location Building-A
snmp-server contact admin@example.com
snmp-server enable traps snmp linkdown linkup
snmp-server host 192.168.1.100 version 2c public

What is the effect of this configuration?

A
The router will send SNMP traps to 192.168.1.100 using community string 'public' for linkdown and linkup events.
The 'snmp-server enable traps snmp linkdown linkup' enables those traps, and the 'snmp-server host' command sends them to 192.168.1.100 with community 'public'.
B
The router will send SNMP traps to 192.168.1.100 using community string 'private' for all SNMP traps.
Why wrong: The 'snmp-server host' command uses community 'public', not 'private'. Also, only linkdown and linkup traps are enabled, not all traps.
C
The router will only accept SNMP read requests using community 'public' and write requests using community 'private'.
Why wrong: While 'public' is RO and 'private' is RW, the question asks about the effect of the entire configuration, which includes trap generation. This option is incomplete.
D
The router will send SNMPv3 traps to 192.168.1.100 using authentication.
Why wrong: The configuration uses 'version 2c', not SNMPv3. No authentication is configured.

Correct answer & explanation

✓

The router will send SNMP traps to 192.168.1.100 using community string 'public' for linkdown and linkup events.

The configuration enables SNMPv2c with read-only (RO) and read-write (RW) community strings, sets location and contact information, enables linkdown and linkup traps, and sends traps to the NMS at 192.168.1.100 using community 'public'.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
Use explanations to understand the rule behind the answer.

TExam Day Tips

Underline the problem statement mentally.
Watch for words such as best, first, most likely and least administrative effort.
Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 350-401 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
