Several new coverage cells are required to improve the Wi-Fi network of an organization. Which two standard designs are recommended? (Choose two.)

5GHz provides increased network capacity with up to 23 nonoverlapping channels.
5GHz channel selection requires an autonomous access point.
Cells that overlap one another are configured to use nonoverlapping channels.
Adjacent cells with overlapping channels use a repeater access point.
For maximum throughput, the WLC is configured to dynamically set adjacent access points to the channel.

Answer(s): A,C

How do TCP and UDP differ in the way they provide reliability for delivery of packets?

TCP does not guarantee delivery or error checking to ensure that there is no corruption of data, UDP provides message acknowledgement and retransmits data if lost.
TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking.
TCP is a connectionless protocol that does not provide reliable delivery of data; UDP is a connection-oriented protocol that uses sequencing to provide reliable delivery.
TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake.

Answer(s): B

What are two differences between optical-fiber cabling and copper cabling? (Choose two.)

Answer(s): B,D

How does CAPWAP communicate between an access point in local mode and a WLC?

The access point must not be connected to the wired network, as it would create a loop
The access point must be connected to the same switch as the WLC
The access point must directly connect to the WLC using a copper cable
The access point has the ability to link to any switch in the network, assuming connectivity to the WLC
