Which two characteristics describe the access layer in a three-tier network architecture? (Choose two.)

A. serves as the network aggregation point
B. physical connection point for a LAN printer
C. designed to meet continuous redundant uptime requirements
D. layer at which a wireless access point connects to the wired network
E. provides a boundary between Layer 2 and Layer 3 communications

Correct Answer: BD

Explanation:

Explanation:
The Access Layer is the one closer to the users. In fact, at this layer, we find the users themselves and the access-layer switches. The main purpose of this layer is to physically connect users to the network. In other words, there is just a cable between end-user PCs, printers, and wireless access points and access-layer switches.

What are the two functions of SSIDs? (Choose two.)

A. uses the maximum of 32 alphanumeric characters
B. controls the speed of the Wi-Fi network
C. used exclusively with controller-based Wi-Fi networks
D. supports a single access point
E. broadcasts by default

Correct Answer: AD

Explanation:

Explanation:
The SSID is a unique identifier that wireless networking devices use to establish and maintain wireless connectivity. The SSID can consist of up to 32 alphanumeric, case-sensitive, characters. Wireless clients connect using the SSID for secure communications. The SSID is a unique token that identifies an 802.11 wireless network. It is used by wireless devices to identify a network and to establish and maintain wireless connectivity. An SSID must be configured and assigned to a wireless client device interface before the device can associate with an access point.

Why is UDP more suitable than TCP for applications that require low latency such as VoIP?

A. UDP reliably guarantees delivery of all packets: TCP drops packets under heavy load
B. UDP uses sequencing data for packets to arrive in order TCP offers the capability to receive packets in random order
C. TCP uses congestion control for efficient packet delivery: UDP uses flow control mechanisms for the delivery of packets
D. TCP sends an acknowledgement for every packet received: UDP operates without acknowledgments

Correct Answer: D
