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 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 for sequencing

TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake

allows access restrictions to be implemented between subscriber sites.

provides direct connections between subscribers

supports Layer 2 VPNs

supports application optimization

TCP transmits data at a higher rate and ensures packet delivery. UDP retransmits lost data to ensure applications receive the data on the remote end.

UDP sets up a connection between both devices before transmitting data. TCP uses the three-way handshake to transmit data with a reliable connection.

UDP is used for multicast and broadcast communication. TCP is used for unicast communication and transmits data at a higher rate with error checking.

TCP requires the connection to be established before transmitting data. UDP transmits data at a higher rate without ensuring packet delivery.

group access points together to increase throughput on a given channel

configure the first three access points are configured to use Channels 1, 6, and 11

include a least two access points on nonoverlapping channels to support load balancing

assign physically adjacent access points to the same Wi-Fi channel

on the router closest to the server

on the router closest to the client

on every router along the path

on the switch trunk interface

DNS server pings the destination to verify that it is available

serves requests over destination port 53

DNS server forwards the client to an alternate IP address when the primary IP is down

responds to a request for IP address to domain name resolution to the DNS server

It is a broadcast IP address

The router does not support /28 mask.

It belongs to a private IP address range.

IT is a network IP address.

conserve public IPv4 addressing

preserve public IPv6 address space

reduce instances of overlapping IP addresses

support the NAT protocol

The environment must be configured with one hypervisor that serves solely as a network manager to monitor SNMP traffic

It allows logical network devices to move traffic between virtual machines and the rest of the physical network

It allows multiple operating systems and applications to run independently on one physical server.

It allows a physical router to directly connect NICs from each virtual machine into the network

It requires that some servers, virtual machines and network gear reside on the Internet
