- A
Rule 1: Trust HTTP from inside to outside; Rule 2: Block all traffic.
Why wrong: Trust rule allows HTTP without inspection, but a default deny rule would block other traffic; however trust is not necessary and could bypass security checks.
- B
Rule 1: Permit HTTP from inside to outside; Rule 2: Block all traffic.
Correct; permit allows HTTP with inspection, and the default deny blocks everything else.
- C
Rule 1: Block all traffic; Rule 2: Allow HTTP from inside to outside.
Why wrong: Block all traffic first would deny HTTP before it can be allowed.
- D
Rule 1: Allow HTTP from inside to outside; no default rule.
Why wrong: Without a default deny rule, all other traffic would be allowed by default.

350-701 Network Security Practice Question
This 350-701 practice question tests your understanding of network security. 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.
An engineer is configuring an access control policy on Cisco FMC for FTD. The policy must allow HTTP traffic from the inside zone to the outside zone, but block all other traffic. Which rule configuration is correct?
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
✓
Rule 1: Permit HTTP from inside to outside; Rule 2: Block all traffic.
Access control rules are processed top-down; a trust rule bypasses further inspection but still allows traffic; a permit rule allows traffic with inspection. The scenario requires allowing HTTP only, so a permit rule for HTTP with a default deny rule after is correct.
Key principle: ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rule 1: Trust HTTP from inside to outside; Rule 2: Block all traffic.
Why it's wrong here
Trust rule allows HTTP without inspection, but a default deny rule would block other traffic; however trust is not necessary and could bypass security checks.
- ✓
Rule 1: Permit HTTP from inside to outside; Rule 2: Block all traffic.
Why this is correct
Correct; permit allows HTTP with inspection, and the default deny blocks everything else.
Related concept
Standard ACLs match source addresses.
- ✗
Rule 1: Block all traffic; Rule 2: Allow HTTP from inside to outside.
Why it's wrong here
Block all traffic first would deny HTTP before it can be allowed.
- ✗
Rule 1: Allow HTTP from inside to outside; no default rule.
Why it's wrong here
Without a default deny rule, all other traffic would be allowed by default.
Common exam traps
Common exam trap: ACLs stop at the first match
ACLs are processed top to bottom. The first matching entry wins, and an implicit deny usually exists at the end.
Detailed technical explanation
How to think about this question
ACL questions test precision: source, destination, protocol, port and direction. A generally correct ACL can still fail if it is applied on the wrong interface or in the wrong direction.
KKey Concepts to Remember
- Standard ACLs match source addresses.
- Extended ACLs can match source, destination, protocol and ports.
- The first matching ACL entry is used.
- There is usually an implicit deny at the end.
TExam Day Tips
- Check inbound versus outbound direction.
- Read the ACL from top to bottom.
- Look for a broader permit or deny above the intended line.
Key takeaway
ACLs process entries top to bottom and stop at the first match. Entry order and interface direction matter as much as the permit or deny statement.
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.
Visual reference
What to study next
Got this wrong? Here's your next step.
Review ACL processing order, placement rules (standard near destination, extended near source), and inbound vs outbound direction. Study wildcard masks and implicit deny. Then practise related 350-701 ACL questions on filtering logic and placement.
