TCP was designed to provide reliable service on top of the unreliable network layer provided by IP. Which two protocols are application layer protocols choose two? Of the remaining answers, IP is a network layer protocol, TCP and UDP are transport layer protocols, and SMTP and HTTP are application layer protocols.
Full Answer
Which two protocols operate at the highest layer of TCP/IP protocol stack?
(Choose two.) Which two protocols operate at the highest layer of the TCP/IP protocol stack? (Choose two.) The application layer is the top layer of the TCP/IP protocol stack. Application layer protocols include HTTP, DNS, HTML, TFTP, POP, IMAP, FTP, and SMTP.
How many layers are in the TCP/IP protocol suite?
This functionality is organized into four abstraction layers and each protocol in the suite resides in a particular layer. The TCP/IP suite is named after its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP).
What are the TCP/IP protocols?
The TCP/IP suite is named after its most important protocols, the Transmission Control Protocol (TCP) and the Internet Protocol (IP). Some of the protocols included in the TCP/IP suite are: ARP (Address Resolution Protocol) – used to associate an IP address with a MAC address.
Which layer of TCP/IP model provides a route to forward messages?
Which layer of the TCP/IP model provides a route to forward messages through an internetwork? The OSI model network layer corresponds directly to the internet layer of the TCP/IP model and is used to describe protocols that address and route messages through an internetwork. 123.
Which two protocols operate at the top layer of TCP IP?
Which two protocols operate at the highest layer of the TCP/IP protocol stack? (Choose two.)DNS.Ethernet.IP.POP.TCP.UDP. Explanation: The application layer is the top layer of the TCP/IP protocol stack. Application layer protocols include HTTP, DNS, HTML, TFTP, POP, IMAP, FTP, and SMTP.
Which two protocols operate at the transport layer of the TCP IP model choose two select one or more?
This name is usually shortened to Transport Layer. The two most important protocols in the Transport Layer are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
What 2 protocols are at the transport layer in TCP IP?
This type of communication is known as end-to-end. Transport layer protocols at this level are Transmission Control Protocol (TCP), User Datagram Protocol (UDP), and Stream Control Transmission Protocol (SCTP).
Which is the topmost layer in TCP IP protocol?
applicationThe table lists the layers from the topmost layer (application) to the lowest (physical network).
Which layer of the TCP IP model is mapped to the bottom two layers of the OSI model?
The application layer maps to the first and third layers of the OSI model. Transport is a direct 1 to 1 mapping. The internet layer maps directly to the network layer and the last two layers of the OSI model map to the network access layer.
Which protocol uses TCP as its transport layer protocol?
SMTP, FTP, and HTTP use TCP.
How many protocols are in the TCP IP suite?
The 4 layers of the TCP/IP model Its protocols include HTTP, FTP, Post Office Protocol 3, Simple Mail Transfer Protocol and Simple Network Management Protocol. At the application layer, the payload is the actual application data.
Which protocols operate at the application layer of the TCP IP model?
Application layer includes all the higher-level protocols like DNS (Domain Naming System), HTTP (Hypertext Transfer Protocol), Telnet, SSH, FTP (File Transfer Protocol), TFTP (Trivial File Transfer Protocol), SNMP (Simple Network Management Protocol), SMTP (Simple Mail Transfer Protocol) , DHCP (Dynamic Host ...
What are the 4 TCP IP layers?
4 The TCP/IP Protocol Stack is made up of four primary layers: the Application, Transport, Network, and Link layers (Diagram 1). Each layer within the TCP/IP protocol suite has a specific function.
What is the command show IP?
Explanation: The command show ip interface brief shows the IP address of each interface, as well as the operational status of the interfaces at both Layer 1 and Layer 2. In order to see interface descriptions and speed and duplex settings, use the command show running-config interface. Next-hop addresses are displayed in the routing table with the command show ip route, and the MAC address of an interface can be seen with the command show interfaces.
What is a default gateway address?
Explanation: A default gateway address is typically configured on all devices to allow them to communicate beyond just their local network.In a switch this is achieved using the command ip default-gateway .
How many bits are in 192.168.1.64/26?
Explanation: For the subnet of 192.168.1.64/26, there are 6 bits for host addresses, yielding 64 possible addresses. However, the first and last subnets are the network and broadcast addresses for this subnet. Therefore, the range of host addresses for this subnet is 192.168.1.65 to 192.168.1.126. The other subnets do not contain the address 192.168.1.96 as a valid host address.
Why are UTP wires twisted together?
Twisting the wires together causes the magnetic fields of each wire to cancel each other out.
Do switches need IP addresses?
Explanation: A switch, as a Layer 2 device, does not need an IP address to transmit frames to attached devices. However, when a switch is accessed remotely through the network, it must have a Layer 3 address. The IP address must be applied to a virtual interface rather than to a physical interface.
Can a host communicate with other hosts?
The host cannot communicate with other hosts in the local network. The host cannot communicate with hosts in other networks. A ping from the host to 127.0.0.1 would not be successful. The host will have to use ARP to determine the correct address of the default gateway.
