1. A network technician is asked to examine an existing switched network. Following

this examination, the technician makes recommendations for adding new switches

where needed and replacing existing equipment that hampers performance. The

technician is given a budget and asked to proceed. Which two pieces of information

would be helpful in determining necessary port density for new switches? (Choose

two.)

forwarding rate

*traffic flow analysis

*expected future growth

number of required core connections

number of hubs that are needed in the access layer to increase performance

2. Configuring communication between devices on different VLANs requires the use

of which layer of the OSI model?

Layer 1

*Layer 3

Layer 4

Layer 5

3. What is the likely impact of moving a conventional company architecture to a

completely converged network?

Local analog phone service can be completely outsourced to cost-effective providers.

The Ethernet VLAN structure is less complex.

*A shared infrastructure is created resulting in a single network to manage.

QoS issues are greatly reduced.

There is less bandwidth competition between voice and video streams.

4. Which hierarchical design model layer controls the flow of network traffic using

policies and delineates broadcast domains by performing routing functions between

virtual LANs (VLANs)?

application

access

*distribution

network

core

5. A network administrator is selecting a switch that will operate at the network core.

Which three features should the switch support for optimum network performance

and reliability? (Choose three.)

port security

security policies

*10 Gigabit Ethernet

*quality of service (QoS)

*hot-swappable hardware

Power over Ethernet (PoE)
