Please verify if my networking answers are correct or not
* Question Completion Status: QUESTION 18 Do wireless networks require an access point (AP) to function? O No, devices can connect into a regular switch with a CAT5 or CAT6 cable. O No, devices can connect to each other in a peer-to-peer network. O Yes, the AP serves the same purpose as the switch does in an Ethernet network. O Yes, otherwise they would be unable to connect to the Internet. QUESTION 19 Suppose I was attempting to make a network crossover cable and had wired one end as Type A. What type of wiring would I need for the other end? O Type A O It doesn't matter. О уре С O Type B QUESTION 20 How do we avoid hidden terminals? O Make sure routing tables are updated with all MAC addresses O Broadcast an RTS and wait for a CTS O Wait for a short period of time before sending O Make sure every device registers as being present on the network Click Save and Submit to save and submit.
