An MPLS service provider is offering a standard EoMPLS-based VPLS service to Customer A, providing Layer 2 connectivity between a central site and approximately 100 remote sites. Customer A wants to use the VPLS network to carry its internal multicast video feeds which are sourced at the central site and consist of 20 groups at Mbps each. Which service provider recommendation offers the most scalability?

• A.EoMPLS-based VPLS can carry multicast traffic in a scalable manner
• B.Use a mesh of GRE tunnels to carry the streams between sites
• C.Enable snooping mechanisms on the provider PE routers
• D.Replace VPLS with a Layer 3 MVPN solution to carry the streams between sites

A new high availability DB sever cluster is installed in the network.
These two servers require high bandwidth and low latency Layer 2 connectivity for database replication.
Which solution supports these requirements?

• A.Add two new links between SW1 and SW2 configured as REP segment 3
• B.Add two new links between SW1 and SW2 configured as REP segments 1 and 2 respectively
• C.Add secondary links to REP segments 1 and 2
• D.Add two new links between SW1 and SW2 configured as LACP trunk with STP

OSPF is running as the IGP to provide reachability to all AS100 networks R3 and R4 are the current ABRs at the boundary of OSPF Area0 and Areal Now BGP must be deployed within AS 100 because it will be receiving Internet routes from its eBGP peers (the service provider) connected to R1 and R2 What is an optimal solution for this deployment to configure BGP relationships and redistribute BGP learned routes into OSPF?

• A.Configuration should be set up with R1 and R2, and R3 in one sub AS, with and R4 in another, and redistribution at R1 and R2.
• B.R1, R2, R3 and R4 must be set up with a neighbor relationship with R5 only must not be a route reflector.
• C.A full mesh should be deployed between all the routers with mutual redistribution to take place at R1 and R2.
• D.R5 should be configured as a route reflector for R1, R2, R3 and R4. BGP routes must be redistributed at R1 and R2 into OSPF.

This network is running OSPF and EIGRP as the routing protocols Mutual redistribution of the routing protocols has been contoured on the appropriate ASBRs The OSPF network must be designed so that flapping routes m EIGRP domains do not affect the SPF runs within OSPF The design solution must not affect the way EIGRP routes are propagated into the EIGRP domains Which technique accomplishes the requirement?

• A.route summarization the ASBR interfaces facing the OSPF domain
• B.route summarization on the appropriate ABRS.
• C.route summarization on EIDRP routers connecting toward the ASBR
• D.route summarization on the appropriate ASBRS.

You were tasked to enhance the security of a network with these characteristics:
* A pool of servers is accessed by numerous data centers and remote sites
* The servers are accessed via a cluster of firewalls
* The firewalls are configured properly and are not dropping traffic
* The firewalls occasionally cause asymmetric routing of traffic within the server data center.
Which technology should you recommend to enhance security by limiting traffic that could originate from a hacker compromising a workstation and redirecting flows at the servers?

• A.Limit sources of traffic that exit the server-facing interface of the firewall cluster with ACLs.
• B.Deploy uRPF loose mode
• C.Deploy uRPF strict mode.
• D.Poison certain subnets by adding static routes to Null0 on the core switches connected to the pool of servers.
