A network architect is planning an update of the server access layer in a data center. Currently,

the access layer switches have 10G links to distribution layer switches. In the new solution, HP
5930 Switches act as top of rack (ToR) switches with 40G links to core switches.
Which factor must the network architect consider when designing solution?

Refer to the exhibit.

A network architect has designed the topology shown in the exhibit. The Gigabit links between
distribution layer and the core uses OM3 grade multi-mode fiber between 100m and 150m long.
The solution is for an enterprise customer whose employees use mostly HTTP-based applications
and have medium utilization needs.
What should the network architect do to resolve a potential issue?

A customer requires high availability, so the network architect is planning two area border (ABRs)
for each non-backbone area in the Open Shortest Path First (OSPF) solution. What ensures a
loop-free routing environment that meets the customer needs?

Refer to the exhibit.

The network architect is planning network addresses for the VLANs shown. The company is using
the private 10.0.0.0/8 space. Which guidelines should the network architect follow?

A company is upgrading a data center network solution in phases. The first phase involves
updating the top of rack (ToR) switches in one rack. Other switches will be updated in their
phases.
What is one benefit of this approach?

Refer to the exhibit.

The exhibit shows how two NICs on a physical server connect to two HP 5820 switches. The
server supports eight virtual machines (VMs) with VMware version 5.1. The VMware standard
virtual switch is bound to NIC and NIC2. This switch implements source MAC load balancing for
the NIC team.

What is the proper configuration for ports 1/0/1 and 2/0/1?

Refer to the exhibit.

A network architect is proposing this solution to a customer. The customer network manager has a
preference for Cisco VLAN Spanning Tree Plus (PVST+) because this protocol provides for fast
convergence when a link fails and also provides per-VLAN load-sharing over links.
How would the network architect explain why the solution fits these requirements?

A network architect is explaining the differences between deploying two switches in an HP
Intelligent Resiliency Framework (IRF) virtual switch and deploying two switches that implement
standard Virtual Routing Redundancy Protocol (VRRP). Which statement correctly describes an
advantage of IRF?

Which data center characteristics should specifically make the architect consider switches that
support Shortest Path Bridging (SPB) or Transparent Interconnection of Lots of Links (TRILL)?

A network architect is planning a complete access layer and core upgrade for customer’s campus
LAN. The campus has four large buildings, each requiring between 1000 and 3000 edge ports.
Which factor will play a primary role in determining whether the network architect needs to plan a
two-tier or three-tier topology for the campus LAN?
