Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q56-Q61):

NEW QUESTION # 56
Your network operations team is deploying Access Control Lists (ACLs) across your Internet gateways They wish to place an ACL inbound on the Internet gateway interface facing the core network (the "trusted" interface). Which IP address would the ACL need for traffic sourced from the inside interface, to match the source address of the traffic?

Answer: A


NEW QUESTION # 57
An engineer is designing the QoS strategy for Company XYZ. Based on initial analysis, a lot of scavenger type of traffic is traversing the network's 20Mb Internet link toward the service provider. The new design must use a QoS technique that limits scavenger traffic to 2 Mbps, which helps avoid oversubscription of the link during times of congestion. Which QoS technique can be used to facilitate this requirement?

Answer: C


NEW QUESTION # 58
Refer to the exhibit.

As part of a redesign project, you must predict multicast behavior. What happens to the multicast traffic received on the shared tree (*,G), if it is received on the LHR interface indicated?

Answer: D

Explanation:
In PIM Sparse Mode, when the Last-Hop Router (LHR) receives multicast traffic on the shared tree (*,G), it performs an RPF check based on the RP address, not the multicast source address. In the diagram:
* The LHR has IGP cost 10 towards the RP.
* The shared tree (*,G) uses RP as the RPF target.
* Since multicast traffic on (*,G) arrives on the interface toward RP (correct RPF interface), the RPF check succeeds.
Therefore, the multicast traffic is successfully switched toward the receivers.
This behavior is fully aligned with CCDE v3.1 multicast design principles, which emphasize clear understanding of RPF behavior both on shared trees (*,G) and source trees (S,G).
Why other options are incorrect:
* A: The RPF check is not performed against the source in (*,G); it uses RP.
* B: RPF checks are always performed, even on (*,G).
* D: RPF is unrelated to the receiver address.
