200-201 Practice Question: Refer to the exhibit
Exhibit
%SEC-6-IPACCESSLOGS: list 101 denied tcp 192.0.2.5(12345) -> 10.1.1.100(23), 1 packet %SEC-6-IPACCESSLOGS: list 101 permitted tcp 192.0.2.5(12345) -> 10.1.1.100(80), 1 packet
Refer to the exhibit. A security analyst views these log entries from a Cisco router. What conclusion can be drawn about ACL 101?
⚠ Common exam trap
Cisco often tests the sequential processing of ACLs and the specific protocol/port mappings (TCP 23 for Telnet, TCP 80 for HTTP) to see if candidates can correctly interpret log entries rather than just the ACL configuration.
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
✓
ACL 101 denies Telnet and permits HTTP
ACL 101 contains an explicit deny statement for TCP port 23 (Telnet) followed by a permit statement for TCP port 80 (HTTP). Since ACLs process rules sequentially, Telnet traffic is denied and HTTP traffic is permitted. This matches option C exactly.
