What else can I help you with?
Which statement correctly describes a function of a layer 2 shitch?
IT uses the destination MAC address to selectively forward a frame
What is significant about the contents of the destination address field?
The destination address field in a frame refers to the physical (or MAC) address of the destination node.
What would happen when you manually added an entry you entered the correct i p address but the wrong Ethernet address for that remote interface?
Once the router/adaptor received the destination IP address (even if we entered in the incorrect MAC address) the router/adapter would remove the IP address from the Ethernet frame and using ARP, would get the correct MAC address of the destination
What part of a packet is used to get to destination?
Destination address
Are the addresses in a layer 2 switch's MAC address table the final destination address or the next hop address?
Final Destination Address
What is in the layer 3 header?
destination host logical address
Which protocol enables a host to determine a destination mac address for a given destination ip address?
DHCP
Which portion of the packet does a router use to forward the packet to the destination?
The Destination Address (Layer 2 or Layer 3)
Which situation Address Resolution Protocol used?
ARP used for resolving mac address from ip address, say one client want to communicate with another and the sender knows only its destination IP address. For communication it requires the physical address of the destination, thus sender uses ARP protocol to resolve the physical address of the destination from ip address by sending arprequest to destination system.
A switch receives a frame with a destination MAC address that is currently not in the MAC table What action does the switch perform?
It duplicates the frame to all Ethernet ports, except the port it came from. A switch's MAC table is built not from destination addresses it receives, but by the source MAC addresses. So the frame is broadcast throughout the broadcast domain, until the end device with a matching MAC address responds to the broadcast, thus giving the switch a new source address to add to its MAC table.
Which operation is used by a router to extract the destination network address from the destination IP address of a packet?
Route table lookup
What is subnet address if the destination address is 198.47.34.31 and sunet mask is 255.255.244.0?
To find the subnet address, perform a bitwise AND operation between the destination address (198.47.34.31) and the subnet mask (255.255.244.0). In binary, the destination address is 11000110.00101111.00100010.00011111 and the subnet mask is 11111111.11111111.11110100.00000000. Performing the AND operation results in the subnet address of 198.47.32.0.
