13 Ιουν 2022 · Explanation: The data link layer consists of two sublayers. These are Logical Link Control (LLC) and Media Access Control (MAC) 3. What is the responsibility of the MAC sublayer? Adds Layer 3 addresses to the frame. Communicates with the network layer (Layer 3) Provides the method to get the frame on and off the media.
30 Μαρ 2020 · RJ-45 port. TCP/IP protocol stack. Explanation: The data link layer describes media access and physical addressing. The encoding of a MAC address on a NIC places it at that layer. Ports and cables are placed at the physical layer of the OSI model. IP addresses are placed at the network layer. The TCP/IP protocol stack describes a different model.
13 Ιουν 2022 · 1. What does the data link layer add to a Layer 3 packet to create a frame? (Choose two.) Explanation: The data link layer adds a header which contains the source and destination Layer 2 address and a trailer that contains a frame check sequence (FCS). 2. What is the function of the last field in a data link layer frame?
1 Απρ 2020 · The data link layer of the OSI model (Layer 2), as shown in the figure, prepares network data for the physical network. The data link layer is responsible for network interface card (NIC) to network interface card communications. The data link layer does the following: Enables upper layers to access the media.
18 Μαρ 2020 · Explanation: The data link layer is actually divided into two sublayers: + Logical Link Control (LLC): This upper sublayer defines the software processes that provide services to the network layer protocols. It places information in the frame that identifies which network layer protocol is being used for the frame.
29 Ιαν 2023 · A LAN design uses a Layer 3 EtherChannel between two switches SW1 and SW2, with port-channel interface 1 used on both switches. SW1 uses ports G0/1 and G0/2 in the channel. However, only interface G0/1 is bundled into the channel and working.
17 Νοε 2020 · Enables IPv4 and IPv6 to utilize the same network interface and media. Adds Layer 2 control information to network protocol data. Integrates various physical technologies. Communicates between the networking software at the upper layers and the device hardware at the lower layers. Provides synchronization between source and target nodes.
4 Μαρ 2020 · They all include the flow control and logical connection fields. Ethernet frame header fields contain Layer 3 source and destination addresses. They vary depending on protocols. They include information on user applications. Explanation: All data link layer protocols encapsulate the Layer 3 PDU within the data field of the frame.
13 Ιουν 2022 · Explanation: The transport layer is responsible for establishing a temporary communication session between the source and destination host applications. 2. Which three are transport layer responsibilities? (Choose three.) Explanation: The transport layer is responsible for conversation multiplexing, segmenting data and reassembling segments ...
4 Μαρ 2020 · Explanation: The data link layer is divided into two sub layers, namely Logical Link Control (LLC) and Media Access Control (MAC). LLC forms a frame from the network layer PDU into a format that conforms to the requirements of the network interface and media. A network layer PDU might be for IPv4 or IPv6.
