An engineering team asks an implementer to configure syslog for warning conditions and error conditions. Which command does the implementer configure to achieve the desired result?

Logging trap 5 corresponds to 'notice' messages, which would include warnings (level 4) and errors (level 3), but the prompt specifically asks for warning and error conditions, so setting it to 4 is more precise for the requested minimum level.

Logging trap 2 corresponds to 'critical' messages, which would not include 'error' (level 3) or 'warning' (level 4) messages.

The `logging trap <severity-level>` command configures the minimum severity level of messages that the router sends to the syslog server. Syslog severity level 4 corresponds to 'warning' messages. Setting the trap level to 4 ensures that messages with severity levels 0 (emergency) through 4 (warning), which includes 'error' (level 3), are sent to the syslog server.

Logging trap 3 corresponds to 'error' messages, which would not include 'warning' (level 4) messages.
