Q1. You are performing a BGP design review for a service provider that offers MPLS-based services to their end customers. The network is comprised of several PE routers that run iBGP with a pair of route reflectors for all BGP address families. Which two options about the use of Constrained Route Distribution for BGP/MPLS VPNs are true? (Choose two.) A. This feature must be enabled on all device
Q1. Tesla Radio GmbH is going to build a new research lab network based on a set of switches that would connect to their existing enterprise network. They are considering a design that would guarantee loop-free behavior within the set of switches. The design would also allow the group of switches to seem like a single switch to the enterprise network, because it is owned by a separate administrat
Q1. You are designing a network that will run EIGRP over a Metro Ethernet service that does not employ a link-loss technology. What will be the impact on convergence if there is a break in the end-to-end Layer 2 connectivity within the service provider network? A. The routers will immediately lose their adjacencies and converge. B. The routing protocol will not converge until the hold timers ha
Q1. Refer to the exhibit. A customer runs OSPF with Area 5 between its aggregation router and an internal router. When a network change occurs in the backbone, Area 5 starts having connectivity issues due to the SPF algorithm recalculating an abnormal number of times in Area 5. You are tasked to redesign this network to increase resiliency on the customer network with the caveat that Router B do
Q1. A Service Provider network designer is considering the use of the G.8032 Ethernet Ring Protection mechanism in order to provide resiliency in the network. Which three concepts will be supported with the implementation G.8032? (Choose three.) A. Ring Protection Link (RPL) B. Ring Automatic Protection Switching (R-APS) C. Multi-Router Automatic Protection Switching (MR-APS) D. Automatic Pro
Q1. A network administrator is in charge of multiple IPsec VPN headend devices that service thousands of remote connectivity, point-to-point, IPsec/GRE tunnels. During a recent power outage, in which it was found that a backup power supply in one of those headend devices was faulty, one of the headend routers suffered a complete shutdown event. When the router was successfully recovered, remote u
Q1. You are deploying a nationwide intranet solution for a company with 4 data centers and 400 remote branches connected via a provider-based solution. As part of the network design, you must ensure efficient content distribution of training material to remote sites. Which two VPN technologies leverage replication in the network core and provide for efficient bandwidth optimization? (Choose two.)
Q1. A senior network designer suggests that you should improve network convergence times by reducing BGP timers between your CE router and the PE router of the service provider. Which three factors should you to consider when you adjust the timer values? (Choose three.) A. access bandwidth B. service provider agreement to support tuned timers C. number of routes on the CE router D. number of
Q1. Your company plans to implement an Internet gateway router that is performing NAT. This same gateway will be terminating various IPsec tunnels to other remote sites. Which address type isappropriate for the ACL that will govern the sources of traffic entering the tunnel in the inside interface? A. inside local B. inside global C. outside local D. outside global View AnswerAnswer: B Q2
Q1. You are the lead network designer hired by Service Provider XYZ to deploy CoS functionality on the core MPLS network (P routers). The goal of the network design is to provide a complete CoS solution to all customers that purchase services such as dedicated Internet access, MPLS L3VPN, and L2VPN (pseudowire). Service Provider XYZ has these design requirements: The network supports four servic
Q1. Which two techniques are used in a network design to slow down the distribution of topology information caused by a rapidly flapping link? (Choose two.) A. Bidirectional Forwarding Detection B. IP event dampening C. link-state incremental SPF D. link-state partial SPF E. LSA throttling F. SPF throttling View AnswerAnswer: BE Q2. You are the lead network designer for an enterprise co
