350-701 Network Security Practice Question
An engineer is configuring a Cisco ASA to allow traffic from the inside (security level 100) to the outside (security level 0). They create an access list permitting HTTP traffic from inside to outside and apply it to the inside interface inbound. What is the expected behavior?
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
✓
The traffic will be allowed because the ACL permits it.
On Cisco ASA, when an ACL is applied inbound on the higher security interface (inside), traffic is evaluated before the stateful inspection. Since traffic from higher to lower security is implicitly allowed by default (based on security levels), the ACL does not need to explicitly permit it; however, applying an ACL inbound on the higher interface can restrict traffic. The ACL as described permits HTTP, so the traffic will be allowed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The traffic will be blocked because the ACL is applied inbound on the inside interface.
Why it's wrong here
Incorrect. Applying ACL inbound on higher security interface can filter traffic, but here it permits the traffic.
- ✗
The traffic will be blocked because the ACL should be applied outbound on the outside interface.
Why it's wrong here
Incorrect. ACL can be applied inbound on the higher security interface to control outbound traffic.
- ✗
The traffic will be allowed only if a NAT rule exists.
Why it's wrong here
Incorrect. NAT may be required for routing, but the ACL is the main factor for permitting traffic.
- ✓
The traffic will be allowed because the ACL permits it.
Why this is correct
Correct. The ACL explicitly permits HTTP, so it is allowed.
