In an MPLS-VPN environment, what is the effect of configuring an identical set of route targets for a particular VRF, but then configuring nonidentical route distinguisher across multiple PE devices?

A. The routes will be correctly handled by the control plane, but there will be instances where routes take up twice as much memory.

B. The routes will propagate to the remote PE, but the PE will never install them in its forwarding table.

C. The routes will be rejected by the remote PE because they have a different RD than its routes.

D. The routes will not even be sent to any remote PE with a different RD.

What are three drawbacks of VPLS? (Choose three.)

A. Direct-attached VPLS requires a full mesh of pseudowires.

B. VPLS cannot support IP bridging (as defined in the VPLS standard).

C. MAC scalability may be problematic, since customer MACs will be visible on the service provider network.

D. VPLS requires a large amount of multicast and broadcast replication.

You have been asked to deploy BGP across a satellite link system to a small number of retail stores.

What must you do to successfully deploy BGP in this situation?

A. configure all the BGP peering sessions across the satellite links as EBGP

B. set the BGP hold timer to under one second

C. configure the initial window size, maximum MTU, and TCP keepalive parameters D. manually configure static routes to back up BGP across the satellite link

Your company's external routers BGP peer with multiple service providers and external organizations. In all cases, the external routers are peered with their BGP neighbors via directly-connected interfaces.

How does GTSM provide additional security for your BGP speakers?

A. GTSM prevents the processing of BGP packets from devices that are not on the directly- connected interfaces.

B. GTSM prevents the formation of BGP adjacencies from unauthorized devices.

C. GTSM ensures that all BGP routing updates have been verified for secure origination.

D. GTSM replaces the TCP 3-way handshake between BGP speakers on directly connected interfaces.

E. GTSM prevents random TCP resets from being injected into the BGP data stream.

A. sub-second IGP hello and dead timers

B. MPLS Traffic Engineering

C. Remote Loop-Free Alternate

D. IP Event Dampening

E. hub and spoke with ECMP

A. BPDU Guard

B. PortFast

C. Loop Guard

D. Port Security

E. UDLD

Which technique can be used to deploy IPv6 services in an IPv4-only routed backbone network?

A. NAT64 at the peering locations

B. 6PE in the backbone network

C. 6RD on CE routers and 6RD border relays at the peering locations

D. dual-stack lite and NAT44 at the peering locations

What is a design consideration of policy-based routing?

A. It should be implemented at both ends of a GRE tunnel.

B. It can limit the network scalability.

C. It can create microloops during network reconvergence.

D. It decreases failure detection time.

What are two base components of both a source-based remotely triggered black hole and a destination-based remotely triggered black hole filtering solution? (Choose two.)

A. NetFlow

B. static route withthe next hop pointing to the Null0 interface

C. infrastructure access list

D. triggered IBGP update setting next hop to a predetermined, unused IP address

E. uRPF
