You are designing an Out of Band Cisco Network Admission Control, Layer 3 Real-IP Gateway
deployment for a customer. Which VLAN must be trunked back to the Clean Access Server from
the access switch?

You are designing a large Frame Relay WAN for a customer. The routing protocol is OSPF. What
is the effect on the routing table if the WAN interfaces are configured as point-to-multipoint?

A company would like to distribute a virtual machine (VM) hosting cluster between three data
centers with the capability to move VMs between sites. The connectivity between data centers is
IP only and the new design should use the existing WAN. Which Layer 2 tunneling technology do
you recommend?

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?

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

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 IGMP snooping
being enabled on both Layer 2 switches and IGMPv2 runs on the hosts. Which design change will
prevent the multicast traffic from being unnecessarily flooded throughout the campus network?

An MPLS service provider is offering a standard EoMPLS-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
recommendation is the most scalable?

You are using iSCSI to transfer files between a 10 Gigabit Ethernet storage system and a 1
Gigabit Ethernet server. The performance is only approximately 700 Mb/s and output drops are
occurring on the server switch port. Which action will improve performance in a cost-effective
manner?

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

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?
