200-201 The meaning of this syslog message? Practice Question
Exhibit
Refer to the exhibit. %ASA-4-106023: Deny tcp src outside:192.168.1.10/12345 dst inside:10.0.0.10/80 by access-group "outside_access_in"
What is the meaning of this syslog message?
⚠ Common exam trap
Cisco often tests the default security-level behavior of the ASA, where candidates mistakenly assume that all denied traffic is from inside to outside, or that the message indicates an error in the access group name rather than a simple deny action.

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
✓
A TCP connection from outside to inside was denied.
The syslog message indicates that a TCP connection attempt from an outside (lower-security) zone to an inside (higher-security) zone was denied by the ASA's implicit or explicit access control. By default, the Cisco ASA denies all inbound traffic from a lower security level to a higher security level unless explicitly permitted by an access-list applied to the interface. The message 'denied' confirms the packet was dropped, not allowed.
