Options

AEach router requires 1 SDP.

BEach router requires 2 SDPs.

DEach router requires 6 SDPs.

Question No: 3

MultipleChoice

By default, what does the Alcatel-Lucent 7750 SR do when a frame with an unknown destination address is received in a VPLS?

Options

AIt drops the frame.

BIt floods the frame to all PEs participating in the service.

CIt sends a destination unreachable message back to the originating host.

Question No: 4

MultipleChoice

On an Alcatel-Lucent 7750 SR, which vc-type will forward service delimiting tags at the ingress PE?

Options

Avc-type ether

Bvc-type vlan

Cvc-type dot1q

Dvc-type null

Question No: 5

MultipleChoice

On the Alcatel-Lucent 7750 SR, which of the following statements about MP-BGP used for a VPRN is TRUE?

Options

ARoutes from different customers with the same IPv4 address prefix are treated as equivalent by MP-BGP.

BMP-BGP will advertise routes to other BGP sessions on the same PE without the need of policies.

CThe multi-protocol nature of MP-BGP allows VPRN routes to be converted into IPv4 routes in the provider core network

DMP-BGP is an enhanced version of BGP that can carry customer route prefixes for multiple VPRNs.

Question No: 6

MultipleChoice

On an Alcatel-Lucent 7750 SR, why must the MTU be explicitly set when configuring an IES spoke termination to a VPLS?

Options

ABy default, a VPLS signals an MTU based on the network port.

BBy default, an IES sets its ip-mtu to the VC MTU of the VPLS

CBy default, an IES uses an MTU value based on its SAP

DBy default, an IES uses an MTU based on the network port.

Question No: 7

MultipleChoice

On an Alcatel-Lucent 7750 SR, which of the following about IES interfaces is FALSE?

Options

AAn IES can only have one interface.

BAn IES interface can have an SDP or a SAP

CAn IES can perform fragmentation.

DAn IES must have an IP address assigned to it.

Question No: 8

MultipleChoice

On an Alcatel-Lucent 7750 SR, the OAM command 'svc-ping' can be used with options bcal-sdp' and 'remote-sdp'. Which of the following is TRUE?

Options

Aiocal-sdp' and 'remote-sdp' indicate that all services using these SDPs are pinged.

B'Iocal-sdp' and remote-sdp' indicate that pings are initiated from both local and remote routers.

CBoth 'Iocal-sdp' and 'remote-sdp' take parameters to specify which SDPs are used for the test.

D'Iocal-sdp' indicates that the ping is sent in-band, and remote-sdp' indicates the return ping is in-band.

Question No: 9

MultipleChoice

Click the exhibit.

PE1 and PE2 are Alcatel-Lucent 7750 SRs. What needs to be added to PE1's configuration to mirror traffic between PE2 and the customer site?

Options

AA 'remote-source' needs to be added to the mirror destination on PEL

BA mirror source needs to be added to PE1 with a 'remote-source'.

CThis is not possible since the protocol analyzer is located at the Central Office. It needs to be at the customer site.

DA mirror source with SAP 1/1/2 needs to be added on PEL

Question No: 10

MultipleChoice

Which of the following about the Alcatel-Lucent 7750 SR's sdp-ping utility is FALSE?

Options

AIt tests uni-directional or round-trip in-band connectivity.

BIt tests the reachability of hosts that are using an SDP.

CIt tests the reachability of the far-end IP address of an SDP through its tunnel.

DIt can be used by specifying only an SDP ID.
