Which mechanism provides a Layer 2 fault isolation between data centers?

Refer to the exhibit.This Layer 2 ring has 10 VLANs with 1000 MAC addresses in each VLAN. Which protocol or
mechanism provides the shortest traffic outage if the link marked with “X” fails?

Refer to the exhibit.On this MPLS-based network ring, links have failed between router A and router E. These
failures formed microloops while the network converged, when A forwarded traffic to B but B
forwards it back to A. Which technology is the simplest solution to avoid microloops without
enabling a new protocol in the network?

There is an MPLS-enabled link constantly flapping on an MPLS VPN network. Given that the
network runs OSPF as the IGP protocol, which design mechanism will stabilize the network and
avoid constant reconvergences?

Which option is a benefit of using N-Port Virtualization?

Youare using iSCSI to transferfiles between a 10 Gigabit Ethernet storage system and a 1
Gigabit Ethernet server.The performanceis only approximately 700 Mb/s and output drops are
occurring on the server switch port. Which action will improve performancein a cost-effective
manner?

An MPLS service provider is offeringa standardEoMPLS-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 5 Mb/s each. Which service provider
recommendationis the most scalable?

Refer to the exhibit.

A new IPv4 multicast-based video-streaming service is being provisioned. During the designvalidation tests, you realize that the link between the two buildings is carrying multicast traffic
even when there are no receivers connected to the switch in Building B and despite IGMPsnooping being enabled on both Layer 2 switches and IGMPv2 runs on the hosts. Which design
change will prevent the multicast trafficfrom being unnecessarily flooded throughout the
campus network?

On a VoIP solution design, which option shows one-way latency, packet loss, and jitter
measurements that ensure acceptable voice quality?

Two medium-sized companies recently merged and would like to share their two campus
buildings as soon as possible. Employees should be able to sit and work in either building. If
the IP addresses in the networks overlap, which virtualization technology could be deployed
quickly to achieve the business objective?
