300-410 Practice Question: Snmp-server community public RO\nsnmp-server…

snmp-server community public RO\nsnmp-server community private RW\nsnmp-server location DataCenter\nsnmp-server contact admin@example.com

What is the effect of this configuration?

⚠ Common exam trap

Cisco often tests the distinction between SNMP versions by hiding the version keyword; candidates assume SNMPv3 is in use when they see 'community', but community strings are exclusive to SNMPv1/v2c.

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

✓

SNMPv2c is enabled with read-only community 'public' and read-write community 'private'.

The configuration uses SNMPv2c community strings 'public' (read-only) and 'private' (read-write), which are plain-text authentication mechanisms. SNMPv2c is enabled by default when community strings are configured, and the 'RO' and 'RW' keywords explicitly define the access levels. This matches option B exactly.

Answer analysis

Option-by-option breakdown

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

  • ✗

    SNMPv3 is enabled with authentication.

    Why it's wrong here

    These commands define SNMPv1/v2c community strings; no v3 user, group, or authPriv settings appear, so v3 authentication is not enabled. SNMPv3 is configured with snmp-server user and snmp-server group commands, which would be the correct approach where encrypted, authenticated polling is mandated.

  • ✓

    SNMPv2c is enabled with read-only community 'public' and read-write community 'private'.

    Why this is correct

    SNMPv2c communities are defined by these commands: 'public' grants read-only access and 'private' grants read-write access, satisfying the stem's requirement to identify the resulting SNMP version and community permissions. The location and contact lines set device metadata only, so they do not alter access levels.

  • ✗

    Only read-only access is allowed using the 'private' community.

    Why it's wrong here

    The 'private' community is mapped to RW, granting read-write access, while 'public' carries RO; the option inverts these mappings. Restricting a community to read-only is achieved with the RO keyword, so this would be correct had 'private' been configured with RO rather than RW.

  • ✗

    SNMP traps are enabled to the location DataCenter.

    Why it's wrong here

    The location command only sets a descriptive sysLocation value returned in MIB queries; it neither enables nor targets traps. Trap delivery requires snmp-server enable traps plus snmp-server host, which would make this the right answer in a configuration that actually defined a trap receiver.
