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?

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?

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

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?

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.

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?

You are designing a large-scale DMVPN network with more than 500 spokes using EIGRP as the
IGP protocol. Which design option eliminates potential tunnel down events on the spoke routers
due to the holding time expiration?

Refer to the exhibit.

In the DWDM network, a ring topology carries multiple services between two sites. Which option
describes the employed protection design?

What is the definition of the ITIL framework?

Refer to the exhibit.

Assume that no multicast optimization is done on LAN switches A and B. Which feature can be
used to optimize multicast traffic forwarding in this situation?
