Application Protocol - governing the way a web server and a web client interact Internet Protocol - taking the segments from the transport protocol, encapsulating them into packets, and assigning them with appropriate addresses Network Access Protocol - Preparing packets to be transmitted over the network media Transport Protocol - Managing the individual conversations between web servers and web clients

What three application layer protocols are part of the TCP/IP protocol suite?

DHCP DNS FTP

Which IEEE standard enables a wireless NIC to connect to a wireless AP that is made by a different manufacturer?

802.11

What is an advantage of network devices using open standard protocols?

Refer to the exhibit. HostA is attempting to contact ServerB. Which two statements correctly describe the addressing that HostA will generate in the process (Choose 2)

A frame with the destination MAC address of RouterA A packet with the destination IP address of ServerB

Which protocol is used by a computer to find the MAC address of the default gateway on an Ethernet network?

ARP

What statement describes the function of the Address Resolution Protocol?

ARP is used to discover the MAC address of any host on the local network

Match each description to its corresponding term

Message encoding - the process of converting information from one format into another acceptable for transmission Message Encapsulation - the process of placing one message format inside another message format Message sizing - The process of breaking up a long message into individual pieces before being sent over the network

What is an advantage of using standards to develop and implement protocols?

Products from different manufacturers can interoperate successfully

Which statement accurately describes a TCP/IP encapsulation process when a PC is sending data to the network?

Segments are sent form the transport layer to the internet layer

A user is viewing an HTML document located on a web server. What protocol segments the messages and manages the segments in the individual conversation between the web server and the web client?

TCP

A user sends an HTTP request to a web server on a remote network. During encapsulation for this request, what information is added to the address field of a frame to indicate the destination?

The MAC address of the default gateway

Which statement is true about the TCP/IP and OSI models?

The TCP/IP transport layer and OSI Layer 4 provide similar services and functions

Refer to the exhibit. PC-A and PC-B are both in VLAN 60. PC-A is unable to communicate with PC-B. What is the problem?

The VLAN that is used by PC-A is not in the list of allowed VLANs on the trunk

If the default gateway is configured incorrectly on the host, what is the impact on communications?

The host can communicate with other hosts on the local network, but is unable to communicate with hosts on remote networks

What will happen if the default gateway address is incorrectly configured on a host?

The host cannot communicate with hosts in other networks

Which statement is correct about network protocols?

They define how messages are exchanged between the source and the destination

broadcast

Which address does a NIC use when deciding whether to accept a frame?

destination MAC address

What process is used to message inside another message for transfer from the source to the destination?

encapsulation

What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly?

flow control

what is a benefit of using a layered model for network communications?

fostering competition among device and software vendors by enforcing the compatibility of their products

Which PDU format is used when bits are received from the network medium by the NIC of a host?
