Questions # 101:

On which component is vc-type configured to create an E-pipe service that preserves the VLAN tag during transport?

Options:

The SDP itself (outside of the epipe context).

The SAP in the E-pipe.

The mesh SDP in the E-pipe.

The spoke SDP in the E-pipe.

Questions # 102:

A VPRN service is configured with BGP used as the CE-PE routing protocol. What address families are required on the PE-CE BGP session?

Options:

VPN-IPv4 address families are required in order for routes to be exchanged with the PE.

Only default IPv4 address families are required since the CE is not aware of the VPRN service

Either IPv4 or VPN-IPv4 address families can be configured on the PE-CE BGP session

An IPv4 address family configuration is required for the PE-PE configuration.

Questions # 103:

Service tunnels and transport tunnels are bidirectional and only require the operator to configure the tunnel on one router.

Options:

TRUE

FALSE

Questions # 104:

If the Alcatel-Lucent 7750 SR is rebooted after an "admin save'' has been performed, which of the following about mirror services is TRUE?

Options:

Only the mirror source must be re-configured.

Only the mirror destination must be re-configured.

Both the mirror destination and mirror source must be re-configured.

Neither the mirror destination nor the mirror source must be re-configured.

Questions # 105:

What is the purpose of service mirroring on the Alcatel-Lucent Service Router?

Options:

To mirror service requirements of a customer with a single branch office and multiple remote sites

To utilize unused ports of a service router until they are required for a service.

To replicate traffic from a service port to another port for debugging or monitoring functions

To ease the configuration burden of services that support a large number of subscribers

All of the above

Which protocol is used to signal the service label for a Layer 3 VPRN service?

Options:

L-LDP

T-LDP

RSVP-TE

MP-BGP

Questions # 107:

An IPv4 MPLS provider network is being configured for 6VPE. BGP is being used for the PE-CE protocol to exchange IPv6 routes. Which of the following is FALSE?

Options:

MP-BGP in the provider network needs to support the VPN-IPv6 address family.

PE routers must be configured to run MP-BGP.

PE-to-CE BGP sessions need to be configured to support IPv6.

The provider network core must be configured to support IPv6.

Options:

5000

5004

5008

5018

Questions # 109:

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

Options:

It drops the frame.

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

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

It sends the frame to the closest neighbor.

Questions # 110:

Which of the following statements about SAPs that are part of a VPVVS is FALSE?

Options:

SAPs can be defined on Ethernet, POS, Sonet/SDH, or TDM channels.

Only one SAP is required for a service that originates and terminates on the same Alcatel-Lucent 7750 SR.

SAPs can have QoS policies assigned to them.

Multiple SAPs can be defined on the same port.

Questions # 111:

In a Layer 2 encapsulation using T-LDP, what does the second (bottom) label represent?

Options:

Tunnel Label

VC Label

Operational Control Word

VPI

VCI

Questions # 112:

How many service labels must be signaled to bring up a fully-meshed VPLS among three PE routers?

Options:

Questions # 113:

Which of the following is TRUE when a service uses a GRE transport tunnel?

Options:

The service takes a route determined by the IGP.

The tunnel does not use a service label.

The service label is swapped at each hop in the transport network.

The tunnel is bidirectional and only requires configuration at one end of the service.

Questions # 114:

In a Layer 2 encapsulation using T-LDP, what does the first (top) label represent?

Options:

Tunnel Label

VC Label

Operational Control Word

UNI

NNI

Questions # 115:

A Cpipe supports both structured and unstructured frames.

Options:

TRUE

FALSE

Questions # 116:

Which of the following best describes the flooding of traffic on a PE when unknown traffic is received on a SAP of a VPLS?

Options:

Traffic is flooded to all SAPs in the service.

Traffic is flooded to all SAPs and spoke SDPs in the service.

Traffic is flooded to all SAPs and mesh SDPs in the service.

Traffic is flooded to all SAPs, spoke SDPs, and mesh SDPs in the service.

The traffic is not flooded.

Questions # 117:

Click the exhibit.

Question # 117

Options:

Questions # 118:

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

Options:

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

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

By default, an IES uses an MTU value based on its SAP.

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

Questions # 119:

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

Options:

An IES can only have one interface.

An IES interface can have an SDP or a SAP.

An IES can perform fragmentation.

An IES must have an IP address assigned to it.
