350-701 Network Security Practice Question
An engineer is configuring a Cisco ASA and needs to ensure that traffic from the outside interface to a web server on the DMZ is allowed. The inside interface is security level 100 and the DMZ is level 50. The outside interface is level 0. Which statement about the default traffic flow is true?
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
✓
Traffic from outside to DMZ is denied implicitly because outside level is lower than DMZ level.
By default, the ASA permits traffic from higher security levels to lower security levels without an ACL. However, traffic from lower to higher levels is implicitly denied. Since outside (0) is lower than DMZ (50), an ACL is required.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Traffic from outside to DMZ is allowed implicitly because the ASA inspects all interfaces equally.
Why it's wrong here
The ASA does not treat all interfaces equally; security levels govern implicit permissions.
- ✓
Traffic from outside to DMZ is denied implicitly because outside level is lower than DMZ level.
Why this is correct
Correct. ASA defaults deny traffic from lower to higher security levels.
- ✗
Traffic from outside to DMZ is allowed implicitly because outside is level 0 and DMZ is level 50.
Why it's wrong here
This contradicts the ASA default behavior; lower to higher is denied.
- ✗
Traffic from outside to DMZ is allowed implicitly because both are lower than inside.
Why it's wrong here
Implicitly, only higher-to-lower is allowed; lower-to-higher is denied regardless of other levels.
