What else can I help you with?
Which statements describe characteristics of extended access lists?
They check packets by source address They check packets by destination address
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.
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 part of a packet is used to get to destination?
Destination address
What is in the layer 3 header?
destination host logical address
Switches have three primary modes to handle frame switching Which one of these modes look at the destination address and then immediately forwards the frame to the destination?
The mode that looks at the destination address and immediately forwards the frame to the destination is called "cut-through switching." In this mode, the switch begins forwarding the frame as soon as it reads the destination MAC address, which reduces latency. However, it does not check the entire frame for errors before forwarding, which can lead to potential issues if the frame is corrupted.
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.
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.
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 another name for unicast address?
Host/destination address
