distribution
network
core
9. Which hierarchical design model layer is
responsible for containing network problems to the workgroups in which they
occur?
application
access
***distribution
network
core
10. Which of the following are characteristics
of the core layer of the hierarchical network design model? (Choose three.)

11. 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
12. 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
13. 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
14. 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
15. Where should DNS and email servers be
located?
IDF
***MDF
HCC
VCC
POP
16. Which LAN standard uses CSMA/CD as its
access method?
FDDI
***Ethernet
Wireless
Token Ring
17. 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.
18. 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
19. Which devices are considered acceptable for
creating more connection points at the end of horizontal cable runs? (Choose
two.)
***hubs
bridges
***switches
routers
20. 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.
