1) In an attempt to improve switch performance, a network administrator changes the MAC aging time to ten seconds. What is a likely result of this decision?
The MAC table will fill with unused addresses.
Address conflicts will cause retransmission errors.
Unnecessary flooding will slow network performance.
Timely MAC address updates will ensure rapid delivery of frames
2) What is the purpose of configuring a switch port as a trunk port?
to control the broadcast domain size
to eliminate the collisions that result from multiple VLANs
to transmit data from multiple VLANs through a single port
to increase the bandwidth between the switch and its upstream device
Refer to the exhibit. All switch interfaces are members of the same VLAN. What information is used by Switch1 to determine if incoming frames from the hosts should be forwarded to Router1?
the source address field in the IP header
the destination port number in the TCP header
the destination address field in the Layer 3 header
the destination address field in the Ethernet header
What operational change will occur if an 802.11b client associates with an access point that is currently supporting clients utilizing 802.11g?
The 802.11g clients will disassociate from the AP.
The 802.11g clients will operate at reduced speeds.
The 802.11b client will never gain access to the channel.
The 802.11b client will not be able to establish an IP session with any of the other 802.11g clients.
