Refer to the exhibit. A retail company has around 500 branches across the U.S. The company is connected to the DC and DR routers through a Frame Relay cloud. All the communication happens only between BR routers to DC or DR routers, and there is no BR router to BR rotter communication. The service provider has decided to discontinue the Frame Relay service and replace it with Metro Ethernet. The retail company currently uses OSPF NBMA mode as IGP, which is the only scenario that the IT team is familiar with. The retail company decides to optimize the data center computing resources with server virtualisation. They have many serve, segments that need Layer 2 connectivity between the DC router and me DR router tor VM failover. Which Metro Ethernet technology uses a minimum of resources from the service provider network?

A small local business recently had an outage after an employee plugged a switch into the corporate network, which caused the traffic pattern in the network to change. You have been tasked to redesign the network so that this does not happen again. From the left side to the right side, drag the PVRST+ features that should be implemented to prevent the corresponding root cause. Not all sources will be used.

Company A has a hub-and spoke topology over an SP-managed infrastructure. To measure traffic performance metrics. IP SLA senders on all spoke CE routers and an IP SLA responder on the hub CE router. What must they monitor to have visibility on the potential performance impact due to the constantly increasing number of spoke sites?

Company X will be integrating an IPv6 application into their network and wants to develop a test environment to evaluate application performance across the network. This application will require both unicast and multicast communications. The company can do this implementation only in certain areas of its existing IPv4-only network, but wants all areas to communicate with each other. When developing the design to provide connectivity between these testing locations, what tunneling technology would work in this scenario?

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.)
