BGP and OSPF are examples of which type of protocol?

Routing

A device receives a data link frame with data and processes and removes the Ethernet information. What information would be the next to be processed by the receiving device?

IP at the internet layer

At which layer of the OSI model would a logical address be added during encapsulation?

Network Layer

Which of the following statements are true regarding network layer and data link layer addresses? (Choose three.)

Network Layer Addresses are logical and data link addresses are expressed at 12 hexadecimals digits. Data Link Layer Addresses are physical and network layer addresses are logical. Network Layer addresses are either 32 bits or 128 bits in length.

What is used to determine the network portion of an IPv4 address?

Subnet Mask

True or false. Standards organizations are usually vendor-neutral.

True

Broadcast

Which message delivery option is used when all devices need to receive the same message simultaneously?

Broadcast

Which two protocols are service discovery protocols? (Choose two.)

DNS DHCP

Which two protocols belong in the TCP/IP model application layer?

DNS DHCP

Which protocol stack layer encapsulates data into frames?

Data link

What process is used to receive transmitted data and convert it into a readable message?

Decoding

What is the order of the two addresses in the data link frame?

Destination MAC, Source MAC

What types of standards are developed by the Electronics Industries Alliance (EIA)?

Electric Wiring and connectors

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

Encapsulation

What is the process of converting information into the proper form for transmission?

Encoding

Which protocol operates at the network access layer of the TCP/IP model?

Ethernet Layer

A web client is receiving a response for a web page from a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to decode the received transmission?

Ethernet, IP, TCP, HTTP

True or False? Data Link addresses are physical so they never change in the data link frame from source to destination.

False

True or false? The right-most part of an IP address is used to identify the network that a device belongs to.

False

Which step of the communication process is concerned with properly identifying the address of the sender and receiver?

Formatting

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

Frame

A web client is sending a request for a webpage to a web server. From the perspective of the client, what is the correct order of the protocol stack that is used to prepare the request for transmission?

HTTP; TCP; IP, Ethernet

Which three acronyms/initialisms represent standards organizations? (Choose three.)

IANA IEEE IETF

Which two protocols function at the internet layer? (Choose two.)

ICMP IP

Which of the following are protocols that provide feedback from the destination host to the source host regarding errors in packet delivery? (Choose two.)

ICMPv4 ICMPv6

This standards organization is responsible for IP address allocation and domain name management.

Internet Assigned Numbers Authority (IANA)

What are two benefits of using a layered network model? (Choose two.)

It assists in protocol design. It Prevents technology in one layer from affecting other layers.

What is done to an IP packet before it is transmitted over the physical medium?

It is encapsulated in a Layer 2 Frame

Which type of communication will send a message to a group of host destinations simultaneously?

Multicast

Which delivery method is used to transmit information to one or more end devices, but not all devices on the network?

Multicasting

What is the purpose of protocols in data communications?

Providing the rules required for a specific type of communication to occur.

Which services are provided by the internet layer of the TCP/IP protocol suite? (Choose three.)

Routing Protocols Messaging Internet Protocols

What is the PDU associated with the transport layer?

Segment

What is the process of dividing a large data stream into smaller pieces prior to transmission?

Segmentation

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

ServerB will generate a frame with the destination MAC address of RouterB. ServerB will generate a packet with the destination IP address of HostA

After making configuration changes on a Cisco switch, a network administrator issues a copy running-config startup-config command. What is the result of issuing this command?

The new configuration will be loaded if the switch is restarted.

A network administrator enters the service password-encryption command into the configuration mode of a router. What does this command accomplish?

This command prevents someone from viewing the running configuration passwords

A network administrator enters the service password-encryption command into the configuration mode of a router. What does this command accomplish?

This command prevents someone from viewing the running configuration passwords.

In computer communication, what is the purpose of message encoding?

To Convert Information to the appropriate form for transmission.

What is the purpose of the sequencing function in network communication?

To uniquely label transmitted segments of datas for proper reassembly by the receiver
