This is used at transport layer of OSI for connection oriented services.
Its three way handshake.
1) SYN
2)SYN-ACK
3)ACK
hence SYN-ACK is the answer.

The loopback address is used to send a packet from the?
host to all
Host A has an IP address of 172.16.225.93 a mask of 255.255.248.0 and a default gateway of 172.16.224.1. Host A needs to send a packet to a new host whose IP is 172.16.231.78. What two things occur?
*Host A will get a result of 172.16.224.0 from the AND process. Host A will send on to the media a broadcast frame that contains the packet. *Host A will broadcast an ARP request for the MAC of the host 172.16.231.78. Host A will change the destination IP of the packet to 172.16.224.1 and forward the packet. Host A will encapsulate the packet in a frame with a destination MAC that is the MAC address associated with 172.16.224.1.
A host with IP address 137.23.56.23 send a packet to a host with ip addrs 142.3.6.9 is the delivery direct or indirect?
Without knowing the subnet mask it is impossible to say.
What are two things will happen if a router receives an icmp packet which has a ttl value of 1 and the destination host is several hops away?
1.The router will discard the packet. 2.The router will send a time exceeded message to the source host.
What will happen if a router received a ICMP packet with TTL 0?
1.The router will discard the packet. 2.The router will send a time exceeded message to the source host.
Should a guest expect a response when they send a thank you gift to a host?
Etiquette dictates that when you, as a guest have sent a gift to thank the host they should at least phone you and thank you.
Host a sends a frame with the destination mac address as ffffffffffff what action will the switch take for this frame?
It will send the frame to all hosts except host A.This is a MAC broadcast address. All hosts on that subnet will receive the packet or frame. With the exception of the sending host of course.
Which device will send a response to the initial tracert packet from PC1?
LON don
Why does a network host need to broadcast an ARP request?
A host on a network needs to broadcast an ARP request to advertise its Mac address. The networking world is very chatty in nature and when a new network host is available it immediately broadcasts its Mac address as with a ARP message. Also when a particular network host needs to send a data packet to another network host available in the same LAN whose Mac address is unknown, the first network host sends out a ARP message requesting for the destination network hosts MAC address.
What are the three features allow TCP to realibly and accuratly track the transmission of data from source to destination?
TCP uses a handshake communication environment to ensure the reliability to the delivery of packets. It does this by having a 'Ack' or acknowledgement number in each packet that's sent. numerically they will increment after each location it has been to, to understand if the packet has been received. Host 1 will send a packet to host with 'ACK' 1, host 2 replies with ACK 2 (yes i am ready), host 1 sends data with ACK 3, etc and vice versa to ensure maximum reliability in receipt and data transfer. I hope i have helped you. Message me if you need more info or more in depth knowledge.
What is data broadcasting in terms of a LAN?
A broadcast packet is sent and received by all systems on a LAN; it can contain any kind of data. The more broadcasting that a LAN does, the slower it will be overall since every device has to read the packet.
How traceroute works?
The "traceroute" program uses ICMP messaging and the time to live (TTL) field in the IP header. It works by sending a packet to the intended host with a TTL value of 1. The first router will send back the ICMP "time exceeded" message to the sending host. Then the traceroute program will send a message with a TTL of 2, then 3, etc. This way it will get information about each router using the information received in the ICMP packets. To get information about the receiving host, the message is sent to a port that is not likely to be serviced by that host. A ICMP "port unreachable" error message is generated and sent back.
