It defines the most common LAN type in the world.
It is the required Layer 1 and 2 standard for internet communication.
It defines a standard model used to describe how networking works.
It connects multiple sites such as routers located in different countries.
Rate this question:
Logical link control is implemented in software.
The LLC sublayer interacts directly with the NIC driver software.
The data link layer uses LLC to communicate with the upper layers of the protocol suite.
The LLC sublayer is responsible for the placement and retrieval of frames on and off the media.
Logical link control is specified in the IEEE 802.3 standard.
Rate this question:
They must be globally unique
They are only routable within the private network.
They are added as part of a Layer 3 PDU.
They have a 32-bit binary value.
Rate this question:
The first three bytes are used by the vendor assigned OUI.
MAC addresses are implemented by software.
The ISO is responsible for MAC addresses regulations.
A NIC only needs a MAC address if connected to a WAN.

Rate this question:
RT1 will send an ARP reply with its Fa0/0 MAC address.
PC2 will send an ARP reply with its MAC address.
RT1 will send an ARP reply with the PC2 MAC address.
SW1 will send an ARP reply with its Fa0/1 MAC address.
SW1 will send an ARP reply with the PC2 MAC address.
Rate this question:
Host A sends an ARP request to the MAC address of host D.
Host D sends an ARP request to host A.
Host A sends out the packet to the switch. The switch sends the packet only to the host D, which in turn responds.
Host A sends out a broadcast of FF:FF:FF:FF:FF:FF. Every other host connected to the switch receives the broadcast and host D responds with its MAC address.
Rate this question:
Only host D
Only router R1
Only hosts A, B, and C
Only hosts A, B, C, and D
Only hosts B and C
Only hosts B, C, and router R1
Rate this question:
They must be forwarded by all routers on the local network.
They are received and processed by every device on the local network.
They are dropped by all switches on the local network.
They are received and processed only by the target device.
Rate this question:
Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port.
On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays.
Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.
Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.
Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.
