What is the primary role of a packet in network communication?

To provide reliable end-to-end communication between applications

To carry data across interconnected networks using logical addressing

To convert data into signals for transmission on the physical medium

To deliver data within a single local network segment

A network technician is capturing traffic on a LAN and sees a frame with a destination MAC address of ff:ff:ff:ff:ff:ff. The frame contains an ARP request. What is the purpose of this frame?

To send a packet to a specific host on a remote network

To notify all hosts of a routing table update

To discover the MAC address associated with a known IP address on the local network

To assign an IP address to a host that just joined the network

A network technician is explaining to a junior colleague how the TCP/IP model and the OSI model relate when a user's web browser sends an HTTPS request. The technician says that the encryption and decryption of the HTTPS session is handled by a layer that exists in the OSI model but is not a distinct layer in the TCP/IP model. Which OSI layer is the technician describing?
