1. Which layer of the hierarchical network design model is
refered to as the high-speed backbone of the internetwork, where high
availability and redundancy are critical?
core layer
2. Which two characteristics are associated with enterprise
level switches? (Choose two.)
high forwarding rate
support link aggregation
3. Which feature supports higher throughput in switched
networks by combining multiple switch ports?
link aggregation
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)?
distribution
5. What is the likely impact of moving a conventional
company architecture to a completely converged network?
A shared infrastructure is created resulting in a single
network to manage.
6. Refer to the exhibit. Beginning with HR servers and
workstations, a network engineer is designing a new security structure for the
network. Which set of policies adheres to the hierarchical network model design
principles?
Configure port security options on S1. Use Layer 3 access
control features on D1 and D2 to limit access to the HR servers to just the HR
subnet.
7. Which three features are commonly supported at the
distribution layer of the Cisco hierarchical network model? (Choose three.)
security policies
quality of service
Layer 3 functionality
8. Configuring communication between devices on different
VLANs requires the use of which layer of the OSI model?
Layer 3
9. Which layer of the OSI model does an access layer LAN
switch use to make a forwarding decision?
Layer 2
10. Which two features are supported at all three levels of
the Cisco three-layer hierarchical model? (Choose two.)
Quality of Service
link aggregation
11. 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.)
traffic flow analysis
expected future growth
12. Which hierarchical design characteristic would be
recommended at both the core and distribution layers to protect the network in
the case of a route failure?
redundancy
13. At which heirarchical layer are switches normally not
required to process all ports at wire speed?
access layer
14. For organizations that are implementing a voice over IP
solution, what functionality should be enabled at all three layers of the
hierarchical network?
quality of service
15. 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.)
10 Gigabit Ethernet
quality of service (QoS)
hot-swappable hardware
16. Link aggregation should be implemented at which layer of
the hierarchical network?
access and distribution
17. What statement best describes a modular switch?
flexible characteristics
18. Which layer of the hierarchical design model provides a
means of connecting devices to the network and controlling which devices are
allowed to communicate on the network?
access
19. A technician is attempting to explain Cisco StackWise
technology to a client that is setting up three stackable switches. Which
explanation accurately describes StackWise technology?
StackWise technology allows up to nine switches to be
interconnected via the use of a fully redundant backplane.
20. Refer to the exhibit. What characteristic of
hierarchical network designs is exhibited by having SW3 connected to both SW1
and Sw2?
redundancy
