200-201 Practice Question: Refer to the exhibit
Exhibit
%ASA-4-106023: Deny tcp src outside:10.0.0.2/1234 dst inside:192.168.1.1/80 by access-group "OUT".
Refer to the exhibit. A security analyst sees this syslog message repeatedly. Which change should the analyst make to reduce the log volume while still detecting the activity?
⚠ Common exam trap
Cisco often tests the distinction between suppressing logs (which hides all future activity) and blocking the source (which stops the activity while still allowing detection of other events), leading candidates to mistakenly choose disabling logging instead of implementing a shun.
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
✓
Implement a shun for source IP 10.0.0.2
Implementing a shun for source IP 10.0.0.2 will block all traffic from that specific host at the Cisco ASA, preventing the repeated syslog message ID 106023 (which indicates denied traffic) from being generated. This reduces log volume while still effectively detecting and stopping the malicious activity, as the shun action drops packets before they are logged.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the access-group to inbound on the outside interface
Why it's wrong here
This would not reduce logs and could break the ACL logic.
- ✗
Add an ACL permit statement for traffic from 10.0.0.2 to 192.168.1.1
Why it's wrong here
Permitting the traffic would increase security risk.
- ✓
Implement a shun for source IP 10.0.0.2
Why this is correct
Shun drops all packets from that IP without logging further, reducing log volume.
- ✗
Disable logging for syslog message ID 106023
Why it's wrong here
This would hide all denied traffic, not just the repetitive source.
