350-701 Network Security Practice Question
A Cisco FTD is configured with an access control policy that includes a rule to allow traffic from a specific source subnet. However, traffic is being blocked. Which TWO possible causes should be checked?
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 source subnet is not correctly defined in the network object.
Rule order matters (first match wins) and if an earlier rule blocks the traffic, the allow rule never applies. Also, intrusion policy could block if set to drop.
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 intrusion policy is set to 'No Inspection'.
Why it's wrong here
No inspection would not block; it would allow.
- ✗
The default action is set to 'Allow'.
Why it's wrong here
If default is allow, traffic would pass unless blocked by a rule.
- ✓
The source subnet is not correctly defined in the network object.
Why this is correct
If the object is incorrect, the rule may not match.
- ✓
The allow rule is placed after a block rule that matches the same traffic.
Why this is correct
AC rules are evaluated top-down; first match applies.
- ✗
The rule has a destination port that is incorrect.
Why it's wrong here
If port is incorrect but other conditions match, it might not block unless the rule is too restrictive.
