Cisco Certified Design Expert Practical Exam

Question 1

Correct Answer:

Question 2

You are redesigning a single-level IS-IS network with 500 routers, which have short-haul and long-haul links Most of the time the routing domain is stable, but periodically interfaces on long-haul links bounce for a short period of time , causing 10 to 20 flaps in a few minutes. The probable cause is local road construction.
Although fast convergence important, the client has concerns about taxing CPU cycles on the older routing platforms. What change should you recommend that both protects the CPU of the older routers during the short periods of excessive flapping, yet does not have an impact on fast convergence for all interface failures?

A. Implement a delay between successive IS-IS LSP packet transmissions on routers with long-haul links

B. Modify hello timers on routers with short-haul links

C. Implement LSP generation throttling on routers with long-haul links

D. Modify the length of time than an LSP remains in the router database without being refreshed on all routers

Correct Answer: A

Question 3

How can EIGRP topologies be designed to converge as fast as possible in the event of a point-to-point link failure?

A. Build neighbor adjacencies in a squared fashion

B. Limit the query domain by use of default routes

C. Limit the query domain b use of summarization

D. Build neighbor adjacencies in a triangulated fashion

E. Limit the query domain by use of distribute lists

Correct Answer: C

Question 4

You are designing an optical network. Your goal is to ensure that your design contains the highest degree of resiliency. In which two ways should you leverage a wavelength-switched optical network solution in your network design? (Choose two.)

A. a wavelength-switched optical network assigns routing and wavelength information

B. a wavelength-switched optical network eliminates the need for dispersion compensating units in a network

C. a wavelength-switched optical network takes linear and nonlinear optical impairment calculation into account

D. a wavelength-switched optical network guarantees restoration based strictly on the shortest path available

E. a wavelength-switched optical network provides fault tolerance for single failures only

Correct Answer: A,C

Question 5

Refer to the exhibit.

In a link failure scenario, what is a benefit of adding APS protected link to the design solution?

A. APS applies QoS policies in case Of link failure

B. APS detects failure on transmission infrastructure based on copper.

C. APS switches traffic to a backup fiber automatically and sends notifications

D. APS detects failure and sends notifications

Correct Answer: C

Question 6

Your client is considering acquiring a new IPv6 address block so that all Ethernet interfaces on the network receive addresses based on their burned-in hardware addresses, with support for 600 VLANs. Which action do you recommend?

A. Acquire a new /60 IPv6 network and subnet it into /70 networks, one per VLAN

B. Acquire a new /60 Ipv6 network and subnet it into /68 networks, one per VLAN

C. Acquire a new/54 IPv6 network and subnet it into /64 networks , one per VLAN

D. Acquire a new /58 IPv6 network and subnet it into /64 networks, one per VLAN

Correct Answer: C

Question 7

Which aspect is a significant disadvantage of containers?

A. Resource consumption

B. Inefficiency

C. Reduced operational overhead

D. Time to deploy

E. Security

Correct Answer: E

Question 8

A network is designed to use OSPF to reach eBGP peers. For eBGP peers to stay stable in case of a link failure, what condition should be avoided?

A. Use an ACL to block BGP in one direction

B. Disable BGP synchronization

C. Advertise IP addresses used on eBGP statements via a normal OSPF area

D. Advertise IP addresses used on eBGP peer statements via eBGP

Correct Answer: D

Question 9

Correct Answer:

Question 10

As a network designer for a major multiservice network, your first assignment is to improve the IS-IS convergence to meet application requirements. Drag and drop the convergence tools or techniques to be used on your proposal from the left into the corresponding convergence phase on the right.

Correct Answer:

Question 11

You are designing dual-homed active/active ISP connections from an enterprise customer for internet services, and you have recommended BGP between the customer and ISP. When three security mechanisms do you enable to secure the connection? (Choose three)

A. uRPF is strict mode

B. remote triggered black holes

C. GTSM

D. IDS

E. uRPF in loose mode

F. Routing protocol authentication

Correct Answer: B,E,F

Question 12

Which IEEE standard is commonly used at the data link layer for an access network, in an IoT environment?

A. Wireless Local Area Network

B. Low-Rate Wireless Network

C. Wireless Regional Area Network

D. Broadband wireless metropolitan Network
