Question 1

Which network management framework can be used to develop a network architecture that contains business requirements analysis, gap analysis, and network diagrams as artifacts to be used for design and implementation later?

Options :

A : TOGAF

B : ITIL

C : FCAPS

D : Cobit

Answer: C

Question 2

A company wants to prioritize voice traffic at their network edge and ensure that it has reserved some minimum bandwidth and treated with priority in the core. QoS is not currently implemented in the core, but MPLS with RSVP as the signaling protocol is already enabled. Which three actions do you recommend to optimize the voice traffic in the core with the minimal changes? (Choose three.)

Options :

A : Create GRE tunnels throughthe core and configure PBR to forward the voice traffic into those tunnels.

B : Enable LDP throughout the core and configure PHB queueing policies based on the MPLS EXP field.

C : Perform class-based tunnel selection to forward voice packets through MPLS tunnels in the core based on the DSCP value.

D : Create RSVP tunnels through the core, reserving a minimum bandwidth for voice traffic.

E : Configure PHB queueing policies on every core node based on the DSCP value.

F : Mark the voice traffic at thenetwork edgewith a specific DSCP value.

Answer: A,C,D

Question 3

You must make IGP redesign recommendation for a client that has old equipment, with low CPU power and memory, that they do not have budget to replace. They are very concerned about CPU load on the routers. They are using IS-IS as the IGP in a single Layer 1 area and all routers are connected to each other with point-to-point links. Which method do you recommend to reduce or limit CPU overhead caused by IS-IS?

Options :

A : Implement wide style metrics for IS-IS on all routers

B : Use mesh groups to limit flooding of LSAs

C : Select a router to act as a pseudonode to limit topology synchronization

D : Divide the routers into multiple areas and implement address summarization

Answer: D

Question 4

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?

Options :

A : After the initial timer exchange. R2 sets its transmission rate to the R1 Desired Min TX interval

B : After the initial timer exchange. R1 sets its transmission rate to the R2 Required Min RX interval

C : Timers renegotiate indefinitely, so the timer exchange phase never converges

D : R2 sets the P-bit on all BFD control packets until R2 sends a packet with the F-bit set

Answer: B

Question 5

You have been asked to design a high-density wireless network for a university campus. Which two principles

would you apply in order to maximize the wireless network capacity? (Choose two.)

Options :

A :

Implement a four-channel design on 2.4 GHz to increase the number of available channels

B : Choose a high minimum data rate to reduce the duty cycle.

C : increases the number of SSlDs to load-balance the client traffic.

D : Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.

E : Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.

Answer: B,D
