Question 1

What are two common approaches to analyzing and designing networks? (Choose two.)

A : bottom-up approach

B : high-low security approach

C : top-down approach

D : left-right approach

E : three-tier approach

Answer: A,C

Question 2

A network engineering team is in the process of designing a lab network for a customer demonstration. The design engineer wants to show that the resiliency of the MPLS traffic Engineering Fast Reroute solution has the same failover/failback times as a traditional SONET/SDH network (around 50MSEC). In order to address both link failure and node failure within the lab typology network, which type of the MPLS TE tunnels must be considered for this demonstration?

A : TE backup tunnel

B : Next-hop (NHop) tunnel

C : FRR Backup tunnel

D : next-next-hop (NNHop) tunnel

Answer: D

Question 3

When designing a WAN that will be carrying real-time traffic, what are two important reasons to consider serialization delay? (Choose two )

A : Serialization delays are invariable because they depend only on the line rate of the interface

B : Serialization delays are variable because they depend on the line rate of the interface and on the type of the packet being serialized.

C : Serialization delay is the time required to transmit the packet on the physical media.

D : Serialization delays are variable because they depend only on the size of the packet being serialized

E : Serialization delay depends not only on the line rate of the interface but also on the size of the packet

Answer: B,D

Question 4

Which two design considerations must be considered when introducing FCoE into an existing network? (Choose two.)

A : The existing network must support a MTU of 3280 bytes

B : All the servers in the data center must be retrofitted with Converged Network Adapters

C : Twinaxial cabling can be used to transmit FCoE traffic between a server and its directly connected Ethernet switch, if it is less than 10 meters away

D : Optical cabling is needed to transmit FCoE traffic between a server and its directly connected Ethernet switch

E : The FCoE QoS markings may overlap with call signaling QoS markings

Answer: A,B

Question 5

In a routed access hierarchical campus design, the access-to-distribution Layer 2 uplink trunks are replaced with Layer 3 point-to-point routed links. Why is it recommended that VLANs are confined on a single access switch rather than span across multiple access switches?

A : to allow for better convergence time

B : to prevent the occurrence of Layer 2 loops

C : to prevent routing black holes

D : to allow for fault isolation

Answer: A
