1. The process of prepending protocol information with information from another protocol is called:
- framing
- encapsulation
- encoding
- packetizing
Explanation: Encapsulation is the process of prepending protocol information with information from another protocol.
2. When an Ethernet frame is sent out an interface, the destination MAC address indicates:
- The MAC address of the device, which is on this network, that will receive the Ethernet frame.
- The MAC address of the NIC card of a device, which is on this network or another network, that will receive the Ethernet frame.
- The MAC address of the NIC card that sent the Ethernet frame.
- The MAC address of the router.
Explanation: When an Ethernet frame is sent out an interface, the Destination MAC address indicates the MAC address of the device, which is on this network, that will receive the Ethernet frame.
3. Which Ethernet frame field indicates the beginning of an Ethernet frame?
- Type/Length
- Destination MAC Address
- FCS
- Preamble and SFD
Explanation: The Preamble and Start Frame Delimiter (SFD) indicate the beginning of an Ethernet frame.
4. The Ethernet protocol is at what layer of the OSI Model?
- Layer 1 Physical
- Layer 2 Data Link
- Layer 3 Network
- Layer 4 Transport
Explanation: Ethernet operates at layer 2, the data link layer, of the OSI model.
