Exercise 5.2.6 Use your textbook and the Internet to determine the communication steps in an ARP Request and Response. What steps are involved and how is each message sent ( broadcast to all devices or unicast to a single device)? 1. Based on the interface and the forwarding IP address, ARP consults the appropriate ARP cache for an entry for the forwarding IP address. If an entry is found, ARP skips to step 6. 2. If the entry is not found, ARP builds an ARP Request frame containing the MAC address of the interface sending the ARP Request, the IP address of the interface sending the ARP Request, and the forwarding IP address. ARP then broadcasts the ARP Request using the appropriate interface. 3. All hosts receive the broadcasted frame and the ARP Request is processed. If the receiving host's IP address matches the requested IP address (the forwarding IP address), its ARP cache is updated with the address mapping of the sender of the ARP Request. If the receiving host's IP address does…

CSMA/CA (Carrier Sense Multiple Access/Collision Avoidance), instead of CSMA/CD (Carrier Sense Multiple Access/Collision Detect), is the mechanism of random-access control for wireless LAN (IEEE 802.11). Give two reasons why collision detection is not used by IEEE 802.11.

Explain in details with steps  ( necessary diagrams)  how a firewall does address translation when it receives a TCP packet from a remote web server intended for a web client on the private network and the translation table contains the matching tuple needed for NAT.
