ACME Mining has four data centers in Santiago, Cape Town, Mumbai, and Beijing. They are full-mesh connected via a 400 Mb/s EVP-LAN. A 1-TB file transfer occurs daily via FTP between the Santiago and Mumbai data centers. When testing, this data transfer took an â€œunexpected and outrageousâ€ 6 hours, with an average transfer rate of 47 KB/s. The network team provided this information:

Â· LAN bandwidth usage was below 5% at both data centers during transfer.

Â· WAN bandwidth usage was between 20-30% at both data centers during transfer.

Â· The only QoS on WAN is 200 Kb/s strict priority configured for other types of traffic.

Â· There is no QoS on LAN.

Â· The ping RTT average between data centers is 378 milliseconds.

Which action improves the file transfer rate?

Options :

A : Classify the FTP transfer and use the strict priority queue on the WAN

B : Use TFTP instead of FTP

C : Apply WAN optimization techniques at both data centers

D : Use SFTP instead of FTP

Answer: B

Question 2

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 3

What statement describes the application layer as defined in the software-defined networking architecture?

Options :

A : This layer is responsible for collecting the network status such as network usage and topology.

B : This layer contains programs that communicate their desired network behavior to controllers.

C : This layer is responsible for handling packets based on the rules provided by the controller.

D : This layer processes the instructions and requirements sent by networking components.

Answer: B

Question 4

Company ABC uses IPv4-only. Recently, they started deploying new endpoint devices. For operational reasons, IPv6 cannot be disabled on these new endpoint devices. Which security measure prevents the new endpoint from learning an IPv6 prefix from an attacker?

Options :

A : Secure Neighbor Discovery

B : Router Advertisement Guard

C : Prefix Guard

D : Source Guard and Prefix Guard

Answer: B

Question 5

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

Options :

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
