Cisco Certified Design Expert (CCDE) Written Exam Sample Questions (Q223-Q228):

NEW QUESTION # 223
Drag and drop the design use cases from the left onto the correct uRPF techniques used to prevent spoofing attacks Not all options are used.

Answer:

Explanation:

NEW QUESTION # 224
Comparing traditional networks with SDN, where the network is only application aware, what is the advantage of SDN architecture?

A. has faster network convergence time during catastrophic failures
B. is resilient to scale with fixed number of network devices
C. integrates real-time information about networking activity with the applications
D. simplifies device management by managing each device independently

Answer: C

NEW QUESTION # 225
How must the queue sizes be designed to ensure that an application functions correctly?

A. The queuing delay on every device in the chain must be exactly the same to the application required delay.
B. The default queue sizes are good for any deployment as it compensates the serialization delay.
C. The sum of the queuing delay of all devices plus serialization delay in the chain must be less than or equal to the application required delay.
D. Each individual device queuing delay in the chain must be less than or equal to the application required delay.

Answer: C

Explanation:
Application performance depends on the end-to-end delay experienced by the traffic, which includes:
* Queuing delay at each device.
* Serialization delay based on link speed and packet size.
* Propagation delay.
For the application to meet its performance SLA, the total of all delays (queuing + serialization + propagation) must remain within the application's maximum tolerable delay budget. This is critical for delay- sensitive applications such as voice or real-time video.
This directly aligns with CCDE v3.1 business-driven design, where application requirements dictate network performance guarantees.
Why other options are incorrect:
* A: Focusing on individual devices ignores cumulative delay.
* B: Uniform queuing delay isn't practical or necessary.
* C: Default queue sizes are not always suitable for real-time applications.

NEW QUESTION # 226
Which two conditions must be met for EIGRP to maintain an alternate loop-free path to a remote network?
(Choose two.)

A. The Reported Distance from a successor is lower than the local Feasible Distance.
B. A feasible successor must be present.
C. The Feasible Distance from a successor is lower than the local Reported Distance.
D. The feasibility condition does not need to be met.
E. The Reported Distance from a successor is higher than the local Feasible Distance.

Answer: A,B

NEW QUESTION # 227
Two routers R1 and R2 are directly connected through an Ethernet link. Both routers are running OSPF over the Ethernet link and OSPF has been registered with BFD. R1 has been set up to transmit BFD at a 50 ms interval, but R2 can receive only at a 100 ms rate due to platform limitations. What does this mean?

A. After the initial timer exchange. R2 sets its transmission rate to the R1 Desired Min TX interval
B. Timers renegotiate indefinitely, so the timer exchange phase never converges
C. After the initial timer exchange. R1 sets its transmission rate to the R2 Required Min RX interval
D. R2 sets the P-bit on all BFD control packets until R2 sends a packet with the F-bit set

Answer: C
