Data Link Layer is responsible for ____________ to network interface card communications.

• network interface card (NIC)

• network internet control (NIC)

• network international card (NIC)

The Data Link Layer allows Upper Layer Protocols to access the Physical Layer Media.

• True

• False

It encapsulates Layer 3 packets (IPv4 and IPv6) into Layer 2 Frames.

Layer 3 - Network

Layer 2 - Data Link

• Physical Layer

• Data Link Layer

• Network Layer

• Transport Layer

The Data Link Layer does not perform error detection and accepts corrupts frames.

• True

• False

IEEE 802 LAN/MAN standards are not specific to the type of network (Ethernet, WLAN, WPAN, etc).

• True

• False

These are Layer 2 Devices:

• Network Interface Card (NIC)

• Switch

• Router

What is the size allowed for the frame to be accepted in the receiving node?

_____ to _____ bytes

• 64

• 18

• 1518

• 1618

The Data Link Layer consists of two sublayers:

• Logical Link Control (LLC)

• Media Access Control (MAC)

• Internet Protocol (IP)

• Logical Access Control (LAC)

Communicates between the networking software at the upper layers and the device hardware at the lower layers.

• LLC Sublayer

• MAC Sublayer

Is responsible for data encapsulation and media access control.

• LLC Sublayer

• MAC Sublayer
