Question 1

VPLS uses LDP for signaling.

VPLS uses BGP for autodiscovery and signaling.

VPLS uses spanning tree for signaling

Question 2

- (Topic 4)

Incorrect VPI and VCI configuration

Noise, gain hits, or other transmission problems on the data link equipment

ATM cells are dropped due to incorrect ATM routing in the service provider.

A faulty or failing ATM interface.

Question 3

- (Topic 5)
As described in RFC 3270, short-pipe mode operation, the PE to CE egress polices are based upon:

MDRR quantam

topmost label exp value

Question 4

- (Topic 3)

Question 5

- (Topic 4)
Which two statements about a backup tunnel to avoid the SRLGs of its protected interface are true? (Choose two.)

Tunnel is not created unless it avoids SRLGs on the protected interface.

If it is not possible to avoid SRLG of the protected interface, backup tunnel will be created anyways.

If it is not possible to avoid SRLG of the protected interface, backup tunnel will not be created.

Backup tunnel can be created between IGP areas as long as SRLG is configured along the path.

Manually created backup tunnel do automatically avoid SRLG of protected interfaces.

Refer to the exhibit, An engineer is asked to troubleshoot packet drops inside a network which option is true?

HTTP traffic originated by the 10.10.10.0/24 subnet uses up to 10% of the interface bandwidt

However, if no congestion is present, no more bandwidth is allocated to HTTP traffic

SMTP traffic originated by the 10.10.10.0/24 subnet uses up to 10% of the bandwidth, however, if no congestion is present, more bandwidth is allocated to SMTP traffic

SMTP traffic originated by the 10.10.10.0/24 subnet uses up to 10% of the bandwidt
