Questions # 48:

Which of the following statements are TRUE? (Choose two)

Options:
A.

The primary contributors to latency are distance, scheduling, and congestion.

B.

The weighted round robin scheduling algorithm will result in more delay for high priority traffic than the regular round robin algorithm.

C.

The round robin scheduling algorithm will result in less jitter for low priority traffic than a strict priority scheduler.

D.

Packet loss can be reduced by decreasing the amount of buffer space available to a queue.

E.

Latency can be reduced by increasing the amount of buffer space available to a queue.

Questions # 49:

What is the default remote-age timer of a B-VPLS?

Options:
A.

The same timer is used in all VPLS types.

B.

Higher than the default timer of an I-VPLS.

C.

Lower than the default timer of an l-VPLS.

D.

The same timer as an l-VPLS.

Questions # 50:

You are providing a customer two VPLS services in two different Metro networks. VPLS 500 has been configured in Metro 1 and VPLS 900 has been configured in Metro 2. The customer has requested that they have connectivity between the Metro Networks with their existing VPLS services. Which configuration on the PE routers linking the metro networks will allow for VPLS 500 and VPLS 900 to act as a single VPLS service? Assume default values for all VPLS parameters and SDP 999 exists between the metro networks.

Question # 50

Options:
A.

Option A

B.

Option B

C.

Option C

D.

Option D

Questions # 51:

To reduce the amount of flooding between PE devices which of the following steps should be taken?

Options:
A.

Configure the local age timer to be larger.

B.

Configure the local age timer to be lower.

C.

Configure the remote age timer to be larger.

D.

Configure the remote age to be lower.

Questions # 52:

Which of the following functions must a PE router support when participating in a VPLS service? (Choose 3)

Options:

C.

Frame fragmentation

D.

Frame forwarding

E.

Must discard frames with an unknown destination MAC

F.

MSTP

B.

9104

C.

9108

D.

9122

Questions # 54:

Which of the following statements is false?

Options:
A.

VPLS is a bridged LAN service.

B.

VPLS provides L2 VPN services to CEs.

C.

VPLS is a point-to-point service where CEs are presented with point-to-point virtual circuits.

D.

CEs that are members of the same VPLS service instance communicate with each other as if they are connected via a bridged LAN.

Question # 55

The VPLS service MTU on R2 is 1514 bytes. What must the service MTU be on all other routers participating in the VPLS?

Options:
A.

The service MTU must be equal to or smaller than 1514 bytes.

B.

The service MTU must be 1514 bytes.

C.

The service MTU must be equal to or greater than 1514 bytes.

D.

The service MTU can be any value.

Questions # 56:

Question # 56

If the device connected to PE-A in Metro A sends a frame to PE-A that requires replication within the VPLS which devices is PE-A responsible for replicating the frame to?

Options:
A.

PE-A must replicate the frame to all devices participating in the VPLS

B.

PE-A must replicate the frame to all PEs within Metro A

C.

PE-A must replicate the frame to all devices in the Metro A

D.

All of the above

Questions # 57:

Which of the following technologies allows for two explicit VLAN tags to be received from a customer device?

Options:
A.

RSVP-TE

B.

SP-VLAN

C.

QinQ

D.

Dot1Q

Questions # 58:

RSTP blocks a spoke-sdp using a management VPLS. Is traffic affected on an ES using the same transport SDP?

Options:
A.

Yes

B.

No

Questions # 59:

If the max remote-age timer of a B-VPLS is reached, what happens to the remotely learned MAC addresses in the l-VPLS service?

Options:
A.

There is no effect. The MAC addresses for the l-VPLS age out independently of the aging of B-VPLS addresses.

B.

The MAC addresses for the l-VPLS will age out immediately following the remote-age out of the backbone-macs of the B-VPLS.

C.

By default, the remote-age timer of the B-VPLS is configured to 0 and addresses do not age out. The l-VPLS uses its own timer.

D.

The same timer is used for B-VPLS and l-VPLS addresses on the node.

Questions # 60:

Redundant spoke-SDPs are used between 2 Metro networks for redundancy. How can load balancing be achieved across the redundant spoke-SDPs?

Options:
A.

A single management VPLS using RSTP can be used to block different SDPs for different VPLS services.

B.

A single management VPLS using 802.1D-2004 can be used to block different SDPs for different VPLS services

C.

There is no way to have load balancing across redundant spoke-SDPs.

D.

Two management VPLS using RSTP can be used to block different SDPs for different VPLS services.
