1. What type of delivery uses data link layer addresses?
local delivery *
Refer to curriculum topic: 3.3.2
If a device is sending frames to another device on the same local network, it uses ARP to determine the MAC address of the receiving device. The sending device then uses the Layer 2 addresses to send the frames.


2. Which message delivery option is used when all devices need to receive the same message simultaneously?
broadcast *
Refer to curriculum topic: 3.1.1
When all devices need to receive the same message simultaneously, the message would be delivered as a broadcast. Unicast delivery occurs when one source host sends a message to one destination host. The sending of the same message from a host to a group of destination hosts is multicast delivery. Duplex communications refers to the ability of the medium to carry messages in both directions.

3. What is the general term that is used to describe a piece of data at any layer of a networking model?
protocol data unit *
Refer to curriculum topic: 3.3.1
The term protocol data unit (PDU) is used to describe a piece of data at any layer of a networking model. A packet is the PDU at the network layer. A frame is the data link layer PDU. A segment is the PDU at the transport layer.

4. At which layer of the OSI model would a physical address be encapsulated?
data link layer *
Refer to curriculum topic: 3.3.2
Physical addresses are encapsulated at the data link layer. Logical addresses, also known as IP addresses, are encapsulated at the network layer. Port addresses are encapsulated at the transport layer. No addresses are encapsulated at the physical layer.

5. Why are open standards important in the data communications industry?
They enable interoperability between software and hardware from different vendors. *
Refer to curriculum topic: 3.2.3
Open standard protocols facilitate interoperability between software and hardware made by different manufactures. For example, open standards allow a client with a Linux operating system to connect to a server running a Microsoft Windows operating system. They would also be able to successfully exchange data. If all software, hardware, and protocols were proprietary, this would not be possible.

6. Which layer of the OSI model defines services to segment and reassemble data for individual communications between end devices?
transport *

Refer to curriculum topic: 3.2.4
The OSI model consists of seven layers: application, presentation, session, transport, network, data link, and physical. The transport layer defines services to segment, transfer, and reassemble the data for individual communications between the end devices.

7. What three requirements are defined by the protocols used in network communcations to allow message transmission across a network? (Choose three.)
message encoding *
message size *
delivery options *
Refer to curriculum topic: 3.1.1
The protocols used in network communications define the details of how a message is transmitted, including requirements for message delivery options, message timing, message encoding, formatting and encapsulation, and message size.

8. What is the purpose of protocols in data communications?
providing the rules required for a specific type of communication to occur *
Refer to curriculum topic: 3.1.1
Protocols provide rules that define how a message is transmitted across a network. Implementation requirements such as electronic and bandwidth details for data communication are specified by standards. Operating systems are not specified by protocols, but will implement protocols. Protocols determine how and when to send a message but they do not control the contents of a message.

9. What layer of the TCP/IP protocol model determines the best path through the network?
internet *
Refer to curriculum topic: 3.2.4
The TCP/IP model consists of four layers: application, transport, internet, and network access. The internet layer determines the best path through the network.

10. Fill in the blank.
The MAC address of a PC does not change when the PC is moved to a different network because the MAC address is embedded in the.............. of the PC.
NIC
network interface card
Refer to curriculum topic: 3.3.2
The MAC address is also known as the physical or Ethernet address. Because it is encoded on hardware, on the Ethernet NIC, it will stay the same no matter where the NIC is geographically located.


11. Which logical address is used for delivery of data to a remote network?
 destination IP address  *
Refer to curriculum topic: 3.3.2
The destination IP address is used for end-to-end delivery of data to a remote network. The destination MAC address is used for delivery on a local network. The destination port number identifies the application that should process the data at the destination. Source addresses identify the sender of the data.

12. 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. *
Refer to curriculum topic: 3.3.2
A default gateway is only required to communicate with devices on another network. The absence of a default gateway does not affect connectivity between devices on the same local network.

13. Which three acronyms/initialisms represent standards organizations? (Choose three.)
IANA *
IEEE *
IETF *

Refer to curriculum topic: 3.2.3
TCP/IP is a protocol stack that contains a lot of other protocols such as HTTP, FTP, and DNS. The TCP/IP protocol stack is required to be used when communicating on the Internet. A MAC address is an address that is burned into an Ethernet network card. OSI is the 7 layer model that is used to explain how networking works.


14. What type of message is sent to a specific group of hosts?
  static *
multicast *
Refer to curriculum topic: 3.1.1
A communication that has a single source going to a single destination is called a unicast. A communication from a single source to a group of destinations is called a multicast. A communication from a single source to all destinations on the same local network is called a broadcast.
