Which multicast technology provides a large, many-to-many connectivity for a new application
while minimizing load on the existing network infrastructure?

Yourcompany will attach to a new Gigabit Ethernet-based wide area network from the local
service provider for remote connectivity. Each connection will have a 150 Mb/s committed
information rate. For the design of this new service, which QoS mechanism should be used to
ensure low packet loss toward the service provider network?

What should be taken into consideration when designing IPsec networks using Authentication
Header (AH)?

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?

What is the definition of the ITIL framework?

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

Youare 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.

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?
