After this new OSPF design with per-packet load balancing was implemented, Host A reported
that large file downloads from Server A became slow and sometimes failed. The operations
team discovered that packets are arriving out of order on R1. Which cost-conscious redesign
action will fix the issue?

Company A has grown nationwide in the U.S., and each new remote branch has a Metro
Ethernet circuit provisioned back to the data center at the headquarters on the West Coast. The
operations team says that it cannot manage hundreds of circuits as the company continues to
grow. You review the topology and notice that many of the branches are close to each other in
geographical zones. How can you redesign this network to improve manageability and increase
scalability?

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 does
not support the stub area. How can you accomplish this task?

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?
