Which layer of the hierarchical network design model is often referred to as the
At which layer of the hierarch
ical design model do users connect to the network?
Which hierarchical design model layer is responsible for containing network problems
to the workgroups in which they occur?
Which of the following are characteristics of the core layer of the hierarchical
network design model? (Choose three.)

ing 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
A major network upgrade that was designed to improve sp
eed 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?
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.)
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
Where should DNS and email serve
rs be located?
Which LAN standard uses CSMA/CD as its access method?
VLAN1 and VLAN2 have been configured on a switch. What must be done for hosts
on VLAN1 to communicate with hosts o
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
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
to users while limiting broadcast domains?
one router with multiple fast Ethernet interfaces
multiple routers with Fast Ethernet interfaces
port gigabit switches
** switches running VLANs
managed smart hubs
Which devices are considered accepta
ble for creating more connection points at the
end of horizontal cable runs?
Why is it important that the data carrying capacity of vertical cabling be greater than
that of the horizontal cable?
ical 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 o
f the network.
three packets move faster through vertical cabling
