SNCF — Securing Networks with Firepower — Question 111

An administrator is adding a QoS policy to a Cisco FTD deployment. When a new rule is added to the policy and QoS is applied on “Interfaces in Destination Interface Objects”, no interface objects are available. What is the problem?

Answer options

• A. The FTD is out of available resources for use, so QoS cannot be added.
• B. The network segments that the interfaces are on do not have contiguous IP space.
• C. A conflict exists between the destination interface types that is preventing QoS from being added.
• D. QoS is available only on routed interfaces, and this device is in transparent mode.

Correct answer: D

Explanation

The correct answer is D because QoS functionality is restricted to routed interfaces, and devices in transparent mode do not support this feature. Options A, B, and C do not accurately describe the limitations related to QoS application in this context.
