Question 1

A thorough examination of the curant network infrastructure has revealed that several devices have an unusual high CPU load A traffic analysis indicates that control plane protocols and management traffic are affected as the devices are busy processing inbound traffic The networking team is working on updating their design for the entre network to handle situations like this Which feature or technology can be added to help mitigate the problem?

Options :

A : control plane policing

B : deep uterface buffers

C : TCAM carving

D : modular QoS

Answer: A

Question 2

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 3

A customer with a dedicated Frame Relay network is planning to move its circuits onto a service provider MPLS network. Instead of moving to Ethernet access links right away, the customer wants to tunnel the Frame Relay information across the MPLS network using AToM pseudowire. How is QoS information transmitted across an AToM pseudowire?

Options :

A : QoS information is translated into the MPLS EXP bits in the MPLS header

B : QoS information is carried in a control word that is attached to the MPLS frame

C : QoS information is preserved in the Frame Relay header and encapsulated into the pseudowire frame

D : QoS information cannot be transported through a pseudowire and is dropped

Answer: B

Question 4

ABC Corporation wants to minimize the risk of users plugging unauthorized switches and hubs into the network. Which two features can be used on the LAN access ports to support this design requirement? (Choose two.)

Options :

A : BPDU guard

B : bridge assurance

C : root guard

D : port security

E : loop guard

F : edge port

Answer: A,D

Question 5

Refer to the exhibit. Traffic was equally balanced between Layer 3 links on core switches SW1 and SW2 before an introduction of the new video server in the network. This video server uses multicast to send video streams to hosts and now one of the links between core switches is over utilized. Which design solution solves this issue?

Options :

A : Aggregate links using Layer 2 link aggregation.

B : Add more links between core switches

C : Apply a more granular load-balancing method on SW2.

D : Filter IGMP joins on an over-utilized link.

E : Apply a more granular load-balancing method on SW1.
