All connections between switches are 10 Gbps. Switch is an Intelligent Resilient Framework (IRF)
group with two member. Switch2 is an IRF group with two members. Switch1 and Switch2 route all
traffic.
A network architect is designing a solution for a finance company. One of the primary applications
is a multicast application that delivers stock information to IP video screens across the site. The
network architect is seeking a multicast solution that meets these needs:
Simple configuration that the customer’s IT staff can manage and troubleshoot
No single point of failure for the multicast traffic
What is the best solution for this environment and these needs?

Refer to the exhibit.

The branch routers have E1 lines into the Frame Relay Service provider network. The exhibit
shows just one branch, but the network actually has 30 branches. The HP 6600 Series routers,
which are the area border routers (ABRs), have E2 lines into the Frame Relay network.
The routers in the exhibit Open Shortest Path First (OSPF). The enable OSPF on network follows:
In area 2, OSPF is enabled on network 10.2.0.0/16
In area 0, OSPF is enabled on network 10.0.0.0/16
The customer requires resilience at the WAN core. Which design change best supports that
requirement?

Refer to the exhibit.

A network architect has planned redundant links as shown in the exhibit. What should the network
architect do to ensure that the redundant link design is truly resilient?

A network architect is compiling information about the total cost ownership (TCO) for a proposal.
Which factors play a role in TCO?

Refer to the exhibit.

A network architect is designing the logical topology for a campus LAN networking solution. The
customer requires support for 2400 edge ports, which is provided by 10 intelligent Resilient
Framework (IRF) groups at the access layer. This customer does not have a wireless network nor
anticipants adding one in the next two years. However, the customer does want to authenticate
users with 802.1X and use the network RADIUS server to divide users from different groups into
different VLANs. The customer has three user groups, each of which includes between 600 and
900 users.
Additionally, the customer understands that the RADIUS server will require several policies but
wants to keep these policies as simple and easy to maintain as possible.
How can the network architect ensure that the solution meets the customer needs and also follows
best practice?
