- A
The command 'logging rate-limit 200 all' limits all syslog messages to 200 messages per second.
Correct. The 'all' keyword applies the rate limit to every syslog message, regardless of severity.
- B
By default, Cisco IOS applies a rate limit of 100 messages per second to all logging destinations.
Why wrong: Incorrect. By default, no rate limit is applied; the command must be explicitly configured.
- C
The 'logging rate-limit' command can be applied on a per-interface basis using interface configuration mode.
Correct. The command is available in interface configuration mode to limit syslog messages generated by that interface.
- D
The 'logging rate-limit' command only affects messages sent to the console port.
Why wrong: Incorrect. The rate limit applies to all logging destinations (buffer, remote, console) unless specifically overridden.
- E
The 'show logging rate-limit' command displays the current rate-limit configuration.
Why wrong: Incorrect. The correct command is 'show logging' which includes rate-limit information; there is no 'show logging rate-limit' command.
Quick Answer
The correct statements are that the 'logging rate-limit' command can be applied on a per-interface basis using interface configuration mode, and that it limits the number of syslog messages per second to prevent CPU overload. This command is essential for syslog rate-limiting configuration because excessive logging, especially from flapping interfaces or debug events, can spike CPU utilization and disrupt network stability. On the Cisco CCNP ENARSI 300-410 exam, this topic tests your understanding of how to protect control plane resources while maintaining visibility—a common trap is assuming the command applies only globally or that it affects console logging by default. Remember, the 'all' option applies the limit to every message, while 'except' allows specific severities to bypass the rate limit. A useful memory tip: think of "rate-limit per interface" as a firewall for syslog floods—each interface gets its own throttle, keeping the router’s CPU from drowning in chatter.
300-410 Network Logging and Syslog Practice Question
This 300-410 practice question tests your understanding of network logging and syslog. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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.
Which TWO statements about the 'logging rate-limit' command and its effects are correct? (Choose TWO.)

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 command 'logging rate-limit 200 all' limits all syslog messages to 200 messages per second.
The 'logging rate-limit' command limits the number of syslog messages per second to prevent CPU overload. It can be applied globally or per interface. The 'all' option applies the limit to all messages, while 'except' allows certain severities to bypass the limit. The default rate is not unlimited; it depends on the IOS version but typically no rate limit is applied by default. The command does not affect console logging rate by default; it primarily affects logging to buffer and remote servers. The 'show logging' command displays the current rate-limit configuration.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.

Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Trap categories for this question
Command / output trap
Incorrect. By default, no rate limit is applied; the command must be explicitly configured.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
- Authentication checks who the user is.
- Authorization controls what the user is allowed to do after login.
- Privilege levels affect access to EXEC and configuration commands.
- AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
- Do not assume successful login means full administrative access.
- Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
- Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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.
