How to Interpret show snmp group Output for SNMPv3

This 300-410 practice question tests your understanding of snmp troubleshooting. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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.

A network engineer runs the following command to troubleshoot SNMPv3 group configuration:

R1# show snmp group

group name: admin-group security model: v3 auth priv read view: v1default write view: v1default notify view: v1default

Group name: monitor-group security model: v3 auth no priv read view: v1default write view: none notify view: v1default

What does this output indicate?

A
The 'admin-group' requires authentication and encryption, while 'monitor-group' requires only authentication.
admin-group uses 'auth priv' (auth + encryption), monitor-group uses 'auth no priv' (auth only).
B
Both groups require authentication and encryption.
Why wrong: monitor-group does not require encryption.
C
The 'monitor-group' has read-write access.
Why wrong: write view is 'none', so read-only.
D
The groups use SNMPv2c security model.
Why wrong: The security model is v3.

Quick Answer

The answer is that the 'admin-group' requires both authentication and encryption, while 'monitor-group' requires only authentication. This is correct because the security model field in the show snmp group output directly specifies the SNMPv3 security level: "auth priv" means authentication with privacy (encryption), whereas "auth no priv" means authentication only, without encryption. Additionally, the write view of "v1default" for admin-group grants full read-write access, while "none" for monitor-group restricts it to read-only. On the Cisco CCNP ENARSI 300-410 exam, interpreting this output tests your ability to differentiate SNMPv3 security levels and group permissions, a common trap being to confuse "auth no priv" with no security at all—remember that "auth no priv" still requires a username and password, just no encryption. A helpful memory tip is to think of "priv" as "private key" for encryption: if you see "priv," data is encrypted; if you see "no priv," data is sent in the clear but still authenticated.

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 'admin-group' requires authentication and encryption, while 'monitor-group' requires only authentication.

The output shows that 'admin-group' uses security model 'v3 auth priv', which requires both authentication and encryption (privacy). 'monitor-group' uses 'v3 auth no priv', which requires authentication but no encryption. This matches option A exactly.

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

Common exam traps

Common exam trap: answer the scenario, not the keyword

Cisco often tests the distinction between 'auth priv' and 'auth no priv' by presenting output where candidates mistakenly assume both groups require encryption, or confuse 'write view: none' with having write access.

Detailed technical explanation

How to think about this question

SNMPv3 security levels are defined by the combination of 'noAuthNoPriv', 'authNoPriv', and 'authPriv'. The 'auth priv' level requires both the HMAC-MD5 or HMAC-SHA authentication and a privacy protocol like CBC-DES or CFB-AES for encryption. The 'read view', 'write view', and 'notify view' are configured via SNMP views to control MIB access; a 'write view: none' explicitly denies all write operations.

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.

TExam Day Tips

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 300-410 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.

Same concept, more angles

1 more ways this is tested on 300-410

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.

Variation 1. A network engineer runs the following command on Router R1: R1# show snmp group group name: readonly security model: v3 security level: authNoPriv context: <none> read view: iso write view: <none> notify view: <none> Group name: admin security model: v3 security level: authPriv context: <none> read view: iso write view: iso notify view: iso Based on this output, which statement is correct?

medium

✓ A.The 'readonly' group can read all MIB objects because its read view is 'iso'.
B.The 'admin' group requires only authentication, not encryption.
C.The 'readonly' group can send SNMP traps.
D.Both groups have the same security level.

Why A: Option A is correct because the 'readonly' group has a read view set to 'iso', which corresponds to the entire ISO OID tree (1.3.6.1). This means the group can read all MIB objects accessible under that subtree, effectively granting full read access to all standard SNMP MIBs.
