Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q290-Q295):

NEW QUESTION # 290
Company XYZ is connecting its sites over a private WAN The company is planning on implementing multicast routing on the network. The company has a mixture of routers from different vendors Which technique can be used in the multicast routing design to minimize PIM sparse mode configurations?

Answer: B


NEW QUESTION # 291
An engineer must redesign the QoS strategy for Company XYZ The current network is experiencing many dropped packets due to oversubscription of the guaranteed bandwidth allocated by the service provider.
Company XYZ wants a design with a QoS strategy that controls the traffic flow leaving the Edge router to minimize packet drops Which QoS technique can be recommended as a solution?

Answer: D


NEW QUESTION # 292
You are tasked with the design of a high available network.
Which two features provide fail closed environments? (Choose two.)

Answer: A,B


NEW QUESTION # 293
An organization with 9000 users across 40 branches was using modem applications and their 15 years old network equipment failed several times to meet applications and users requirements.
The organization decided for some cost cuttings and to migrate some of applications to the public cloud. Which of the cost related benefits will this migrations and cost cutting realize?

Answer: B

Explanation:
Migrating applications to the public cloud shifts spend from large up-front hardware purchases (CapEx) to pay-as-you-go operational expenses (OpEx).
This aligns with the scenario of replacing failed, aging equipment and doing cost cutting by using cloud services instead of buying new hardware.


NEW QUESTION # 294
Company XYZ wants to redesign the Layer 2 part of their network to use all uplinks for increased performance, support host reachability with conversational learning, and avoid port-channels. Which other technique can be used?

Answer: B

Explanation:
* A (TRILL - Transparent Interconnection of Lots of Links):TRILL enables multipathing at Layer 2, eliminating classic STP blocking, allowing all uplinks to be active simultaneously, and uses IS-IS based control plane for conversational MAC learning.
Other options explained:
* B: LISP operates at Layer 3 for endpoint mobility, not Layer 2 multipathing.
* C: MSTP still blocks some links under normal operation.
* D: Switch stacking merges multiple physical switches into one logical switch but does not provide true multipathing across independent switches.


NEW QUESTION # 295
