This 200-201 practice question tests your understanding of security concepts. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Exhibit
access-list OUT extended permit tcp any host 10.1.1.1 eq 80
access-list OUT extended deny ip any any
access-group OUT in interface outside
Refer to the exhibit. A security analyst is reviewing the ASA configuration. Which traffic will be permitted from the outside interface?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
TCP traffic to host 10.1.1.1 on port 80
The correct answer is C because the ASA configuration shown includes an access-list entry that permits TCP traffic from any source to host 10.1.1.1 on port 80. This is the only rule that explicitly allows traffic from the outside interface to the inside network, and since the outside interface has the access-group applied inbound, only traffic matching this permit statement will be allowed.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Any IP traffic to host 10.1.1.1
Why it's wrong here
The permit rule specifically allows TCP, not all IP.
✗
All traffic from the outside to the inside network
Why it's wrong here
The deny rule blocks all other traffic.
✓
TCP traffic to host 10.1.1.1 on port 80
Why this is correct
The first ACL line permits TCP to 10.1.1.1 port 80.

✗
HTTP traffic from internal hosts to the outside
Why it's wrong here
The access-group applies to inbound traffic on the outside interface, not outbound.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between 'any IP traffic' and 'any TCP traffic' — the trap here is that candidates may assume 'permit tcp any host 10.1.1.1 eq 80' allows all IP traffic to that host, but it strictly permits only TCP with destination port 80.
Detailed technical explanation
How to think about this question
The ASA uses a stateful firewall model where access-lists applied to interfaces control traffic flow. The command 'access-list OUTSIDE_IN extended permit tcp any host 10.1.1.1 eq 80' creates a permit entry for TCP destination port 80, and the 'access-group OUTSIDE_IN in interface outside' applies it to inbound traffic on the outside interface. A common subtlety is that the ASA implicitly denies all traffic not explicitly permitted, so only matching TCP SYN packets to 10.1.1.1:80 will be allowed; return traffic is handled by the stateful inspection engine.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A security administrator must allow nursing staff to reach a patient records server while blocking access from the guest Wi-Fi VLAN. After applying an extended ACL, traffic is still blocked from nursing workstations. The ACL was applied outbound instead of inbound on the wrong interface. Questions like this test ACL direction and placement rules.
