At which layer of the hierarchical design model do
users connect to the network?
application
access
distribution
network
core
2
Which layer of the hierarchical network design model
is often referred to as the backbone?
access
distribution
network
core
workgroup
WAN
3
What will increase the number of broadcast domains in
a network? (Choose two.)
replacing hubs with switches
segmenting the network by
installing a router
creating VLANs for each
workgroup
adding additional hubs to the local
area network
replacing routers with LAN
switches
adding bridges to connect different
workgroups
4
Where should DNS and email servers be
located?
IDF
MDF
HCC
VCC
POP
5
VLAN1 and VLAN2 have been configured on a switch. What
must be done for hosts on VLAN1 to communicate with hosts on
VLAN2?
VLAN overlapping must be enabled on
the switch.
The MAC address must be added to
the ARP table in the switch.
A router must be configured to
allow routing between the VLANs.
An entry in the switching table
must be configured for each VLAN.
Communication between VLANs is
automatically enabled on switches.
6
What type of cabling is specified by TIA/EIA standards
for interconnection of Intermediate and Main Distribution
Facilities?
patch cables of variable
lengths
horizontal cross-connect
cabling
vertical cross-connect
cabling
parallel cross-connect
cabling
7
Which of the following affect network availability?
(Choose three.)
throughput
response time
workstation speed
access to resources
desktop
applications
8
Which of the following are requirements of LAN design?
(Choose three.)
adaptability
manageability
operability
scalability
stability
9
Why is it important that the data carrying capacity of
vertical cabling be greater than that of the horizontal
cable?
Vertical cabling is reserved for
high bandwith video conferencing.
Vertical cabling carries traffic
from the IDF to the user.
Vertical cabling carries traffic
from the enterprise out to the Internet.
Vertical cabling carries traffic
from multiple areas of the network.
Layer-three packets move faster
through vertical cabling.
10
A distribution layer switch operates at which OSI
layers? (Choose two.)
access
data link
network
internet
transport
11
To reduce cost on a new network design, administrators
select switches that initially will have 100 Mbps interface modules
installed but will also have the ability to support 1000 Mbps
interface modules. Which of the LAN design goals are being utilized?
(Choose two.)
sustainability
reliability
manageability
adaptability
functionality
scalability
12
Which of the following are characteristics of the core
layer of the hierarchical network design model? (Choose
three.)
redundant paths
high-level policy enforcement
packet manipulation
media transitions
rapid forwarding of traffic
no packet
filtering
13
Which of the following are features of the access
layer of the hierarchical network design model? (Choose
two.)
inter-VLAN routing
Layer 2 filtering
Layer 3 filtering
microsegmentation
bandwidth
security
14
Which LAN standard uses CSMA/CD as its access
method?
FDDI
Ethernet
Wireless
Token
Ring
15
A network administrator needs to increase bandwidth
and reduce traffic on a network. What should be used in the access
layer of the hierarchical network design model to dedicate bandwidth
to users while limiting broadcast domains?
one router with multiple fast
Ethernet interfaces
multiple routers with Fast Ethernet
interfaces
multi-port gigabit switches
switches running VLANs
managed smart
hubs
16
Which devices are considered acceptable for creating
more connection points at the end of horizontal cable runs? (Choose
two.)
hubs
bridges
switches
routers
17
A major network upgrade that was designed to improve
speed and reliability has recently been completed. Users in one part
of the network are experiencing dramatically decreased throughput
and loss of connectivity. Which of the LAN design goals was not met
for these users?
functionality
sustainability
adaptability
manageability
scalability
18
When designing a LAN, at which layer of the OSI model
does the process of segmenting collision domains occur?
Layer 1
Layer 2
Layer 4
Layer
7
19
Which hierarchical design model layer is responsible
for containing network problems to the workgroups in which they
occur?
application
access
distribution
network
core
20
What is the primary reason for implementing security
and policy routing at the distribution layer?
filtering of core switching
errors
preventing policy and security
issues from burdening the core layer
preventing unnecessary security
policy decisions from burdening the access layer
maintaining a consistent
three-layer security policy
isolating the access layer from
traffic destined for other networks
