Largest Permissible Packet Size

Answer - D.

The AWS documentation mentions the following on MTU.

The maximum transmission unit (MTU) of a network connection is the size, in bytes, of the largest permissible packet that can be passed over the connection.

The larger the MTU of a connection, the more data that can be passed in a single packet.

Ethernet packets consist of the frame, or the actual data you are sending, and the network overhead information that surrounds it.

The correct answer is D. Maximum Transmission Unit (MTU).

The Maximum Transmission Unit (MTU) is the largest packet size in bytes that can be transmitted over a network connection. It is an important parameter that affects the efficiency and performance of network communication.

When data is sent over a network, it is divided into smaller packets for transmission. Each packet contains a header and a payload, where the header contains information about the packet, such as the source and destination addresses, and the payload contains the actual data being transmitted.

The MTU determines the maximum size of the payload that can be included in each packet. If the payload is larger than the MTU, it must be divided into smaller packets, which can add additional overhead and latency to the network communication. On the other hand, if the MTU is set too low, it can result in fragmentation of packets, which can also negatively impact network performance.

Different types of network connections, such as Ethernet, Wi-Fi, and VPNs, have different MTU values. For example, the MTU for Ethernet is typically 1500 bytes, while the MTU for Wi-Fi can vary depending on the specific protocol and network configuration.

In summary, the MTU is an important parameter for network communication that determines the maximum size of packets that can be transmitted over a network connection.
