QUESTION 74
Both ISL and 802.1Q is being used in the Certkiller network. When comparing the
differences in ISL and 802.1Q, which of the following are true? (Select three)
A. 802.1Q allows the encapsulation of multiple trunks within a single trunk.
B. 802.1Q supports fewer VLANs than ISL.
C. ISL is more efficient than 802.1q due to its smaller header size.
D. 802.1Q supports the processing of untagged frames.
E. 802.1Q uses a tag protocol ID of 0×8100

.
QUESTION 75
The Certkiller network is illustrated below:
In the shown diagram, Server Certkiller 1′s default gateway points to Router
Certkiller 1′s VLAN1 interface and Server Certkiller 2′s default gateway points to
Router Certkiller 2′s VLAN2 interface. Between Switch Certkiller 1 and Certkiller 2,
both VLANs 1 and 2 are being forwarded over a trunk. When there is data transfer
between the servers workstations, WS Certkiller 1 and WS Certkiller 2 see a lot of
input traffic.
How can we limit this problem?
A. Increase aging time on routers
B. Disable MAC address aging time on the switches
C. Disable ARP timeout on routers
D. Reduce MAC address aging time on the switches
E. Bring ARP aging time on Routers and MAC address aging time on switches close to
each other
