Which scenario describes a function provided by the transport layer? A student is using a classroom VoIP phone to call home. The unique identifier burned into the phone is a transport layer address used to contact another network device on the same network. A student is playing a short web-based movie with sound. The movie and sound are encoded within the transport layer header. A student has two web browser windows open in order to access two web sites. The transport layer ensures the correct web page is delivered to the correct browser window. A corporate worker is accessing a web server located on a corporate network. The transport layer formats the screen so the web page appears properly no matter what device is being used to view the web site.

A student has two web browser windows open in order to access two web sites. The transport layer ensures the correct web page is delivered to the correct browser window.

A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in its ARP cache. How will the device obtain a destination MAC address?A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in the ARP cache. How will the device obtain a destination MAC address? It will send the frame and use its own MAC address as the destination. It will send an ARP request for the MAC address of the destination device. It will send the frame with a broadcast MAC address. It will send a request to the DNS server for the destination MAC address. It will send an ARP request for the MAC address of the default gateway.

It will send an ARP request for the MAC address of the default gateway.

Refer to the exhibit. The IP address of which device interface should be used as the default gateway setting of host H1? R1: S0/0/0 R2: S0/0/1 R1: G0/0 R2: S0/0/0
