Cisco Certified Design Expert Qualification Exam

Question 1

Which effect of designing a Layer 2 network using the PortFast feature with PVST+ is true?

A. In combination with BPDU filtering, it causes the switch port to stay in the forwarding state

B. It moves the switch port directly to the forwarding state

C. It accelerates the network convergence on the trunk uplinks

D. It shuts down the port when receiving the superior BPDU

Correct Answer: B

Question 2

You want to split an Ethernet domain in two. Which parameter must be unique in this design to keep the two domains separated?

A. STP type

B. VTP domain

C. VLAN ID

D. VTP password

Correct Answer: C

Question 3

When network summaries are created for access networks in a network design, how does it change the behavior of the shortest Path First (spf) running in a backbone area?

A. There would be no change with the SPFs.

B. There would be fewer full SPFs.

C. There would be fewer partial SPFs.

D. There would be fewer incremental SPFs.

Correct Answer: C

Question 4

After the recent implementation of a new design that incorporated GRE tunnels into the network, the network operations staff is seeing the following syslog message in multiple routes on the network -

From a design perspective, what was not taken into account prior to implementing the solution?

A. The tunnel interface on the router is not receiving any keepalives within the specified hold time.

B. The neighboring routers cannot respond within the specified hold time.

C. The interface on the neighboring router that is the source of the tunnel is down.

D. The router is learning the route to the tunnel destination address using the tunnel interface.

E. The interface on the router that is the source of the tunnel is down.

Correct Answer: D

Question 5

Which two design solutions provide IPv6 interdomain multicast? (Choose two)

A. Embedded RP

B. Auto-RP

C. PIM-DM

D. PIM SSM

E. MSDP

Correct Answer: A,D

Question 6

In a MPLS-VPN environment, what is the effect of configuring an identical set of route targets for a particular VRF, but then configuring nonidentical route distinguisher across multiple PE devices?

A. The routes will be rejected by the remote PE because they have a different RD than its routes.

B. The routes will be correctly handled by the control plane, but there will be instances where routes take up twice as much memory.

C. The routes will not be sent to any remote PE with a different RD

D. The routes will propagate to the remote PE, but the PE will never install them in its forwarding table.

Correct Answer: B

Question 7

Which encoding format does cisco ios XE software support for NETCONF?

A. It supports JSON encoding for NETCONF

B. It supports XML encoding for NETCONF

C. It supports YAML encoding for NETCONF

D. It supports HTML encoding for NETCONF

Correct Answer: B

Question 8

Customer XYZ network consists of an MPLS core. IS-IS running as IGP a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer's engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which two concepts about the Overload Bit are true? (Choose two.)

A. It is not recommended on BGP Route Reflectors

B. It can be set on a router until other interacting protocols have signaled convergence.

C. Networks advertised within the LSPs of the respective node will become unreachable

D. It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node.

E. It can be set on a router during the startup process for a fixed period of time

Correct Answer: B,E

Question 9

Which mechanism provides Layer 2 fault isolation between data centers?

A. advanced VPLS

B. OTL

C. fabric path

D. TRILL

E. LISP

Correct Answer: E

Question 10

Which two loop-free Alternate design considerations are true? (Choose two)

A. It can impact SLA-sensitive applications by routing traffic to low bandwidth links while IGP convergence is in progress

B. It can simplify the capacity planning by matching the backup path with the post-convergence path

C. It provides an optimal backup path by avoiding low bandwidth and edge links

D. Backup coverage and effectiveness is dependent on the network topology

E. Cisco MPLS TE must be enabled because it is used for building the backup paths

Correct Answer: A,D
