The mirror destination configuration on PE5 is missing the "remote-source" command.

There needs to be a mirror source configuration on PE5 with the "remote-source" command.

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

There needs to be a configuration command to put sap 1/1/3 on the mirror destination of PE5.

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.

A packet receives a service label and a transport label at the ingress PE.

A packet has its servicelabel swapped at each P router.

The egress PE pops the service label, and the transport label is forwarded.

The service label is popped by the remote CE.

The mesh SDP on router R4 has been shutdown.

The mesh SDP on 10.10.10.1 has been shutdown.

The service MTU on 10.10.10.1 has been set to a different value.

The IngLbl and EgrLbl that router R4 has for 10.10.10.1 are identical.

The IES's interface must be an IGP peer with the CE.

The IES must use an IP address that is different than the C£.

The IES can only include one SAP for the CE.

The IES must include a network port.

They both function as a Layer 2 switch from the service provider's perspective.

They both support SAP encapsulations of null, dot1Q and Q-in-Q.

They both use SAPs as the demarcation point between the customer and the provider.

MAC addresses are learned by VPLSes, but not by E-pipes.

The FCS is verified and kept in the customer frame. The VLAN tag is kept and transported over the network.

Service tunnels are unidirectional.

Transport tunnels are unidirectional.

A service will use the same service label for every hop.

A local service requires a transport tunnel.

Mesh SDPs assist MAC learning by flooding traffic to other mesh SDPs.

A PE keeps a single FDB for all VPLSes it has.

Frames received on a SAP that are broadcast, multicast or unknown are flooded.

The FDB only stores the MAC addresses of remote sites.

VPRN is an IP service that connects multiple sites in a single routed domain over the provider-managed IP/MPLS network.

Each VPRN consists of a set of customer sites that must connect to the same PE router

In a VPRN service, each customer router becomes a routing peer to other customer routers

VPRN provides customer routers with transparent IP connectivity without knowledge of the MPLS core

A VRF contains a single VPRN routes.

Every VRF in a PE is associated with one or more route target attributes.

Each VPRN needs a separate VRF in each PE router.

On the 7750 SR, by default, there is a unique one-to-one association between a VPN label and a VRF

All of the above statements are true.

All of the above statements are false.

The service label is swapped for a transport label during transport.

The transport label is used to forward packets between PEs.

The service label is used to identify which VPRN a packet belongs to.

Labels are initially added at the ingress PE.

VPN-IFV4 allows multiple customers to have overlapping IP addresses.

CE routers use VPN-IPv4 prefixes to differentiate between services.

PE routers are responsible for creating VPN-IPv4 prefixes.

A VPN-IFV4 prefix is composed of a route distinguisher (RD) and an IPv4 address.

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.

An IES has a configurable VC MTU.

An IES interface has an IP address assigned to it.

IES supports QoS.

An IES requires a spoke SDP.

The frame egresses 1/1/1:6.7 with an outer VLAN tag of 6 and inner tag of 7.

The frame is dropped at the egress SAP 1/1/1:6.7.

The frame egresses 1/1/1:6.7 with VLAN tag 5.

The frame egresses 1/1/1:6.7 with VLAN tag 6.

It will show the hops taken between service endpoints.

It will test the delay across the service.

It will test the SDPs of a service in both directions.

It will test the round-trip connectivity of the service.

An IES requires a spoke SDP.

A virtual route table must be configured for an IES service.

An IES service must use static routes to communicate with customer networks.

An IES must have at least one SAP defined.

Route targets are carried in MP-BGP updates.

Route targets identify the VRF that a VPN-IFV4 prefix is associated with.

Route targets are communicated between PEs that are part of a specific VPRN.

Route targets identify the egress SAP of a service towards a CE.

Yes. A routing policy is required to advertise routes between PE routers in a VPRN

No. A routing policy is not required; the default behavior on the 7750 SR is to advertise all VPRN routes between PE routers.

A routing policy is required only when BGP is used as the PE-CE routing protocol, as shown in the exhibit.

A CE1 system interface can not be advertised to PE2 since the CE routers are not aware of the VPRN.

The FCS is verified and the customer frame is transported intact over the service provider network.

The FCS is verified and kept in the customer frame. The VLAN tag is removed for transport over the network.

A "remote-source" needs to be added to the mirror destination on PEL

A mirror source needs to be added to PE1 with a "remote-source".
