application
access
*** distribution
network
core
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

*** functionality
sustainability
adaptability
manageability
scalability
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

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
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

*** hubs
bridges
*** switches
routers
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
