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.
Refer to the exhibit. The switches are in their default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway. Which network hosts will receive the ARP request sent by host A?
What statement describes the treatment of ARP request on the local link?
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.
What are two potential network problems that can result from ARP operation? (Choose two.)
Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.
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.
Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.
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.
Fill in the blank. A collision fragment, also known as a [blank_start]runt[blank_end] frame, is a frame of fewer than 64 bytes in length.
Fill in the blank. On a Cisco switch, [blank_start]port-based[blank_end] memory buffering is used to buffer frames in queues linked to specific incoming and outgoing ports.
Fill in the blank. ARP [blank_start]spoofing[blank_end] is a technique that is used to send fake ARP messages to other hosts in the LAN. The aim is to associate IP addresses to the wrong MAC addresses.
