CSMA/CD stands for Carrier Sense Multiple Access with Collision Detection. It is a method used on Ethernet networks to detect data collisions. In CSMA/CD, devices on the network first listen for any ongoing transmissions. If the network is idle, a device can start transmitting data. However, if two devices start transmitting at the same time and a collision occurs, CSMA/CD detects the collision and stops the transmission. It then waits for a random period of time before retransmitting the data. This method helps to ensure that data collisions are detected and managed effectively on the Ethernet network.Rate this question:

Your boss calls to tell you that as of today all of the company's WAPs must be made as secure as can be. Which of these steps would you take on each WAP? (Choose all that apply)
-
Upgrade to WEP encryption
-
Upgrade to WPA2 encryption
-
Disable the SSID broadcasts
-
Use the Default SSID
-
Use MAC filtering
Correct Answer(s)
A. Upgrade to WPA2 encryption
A. Disable the SSID broadcasts
A. Use MAC filteringExplanation
Upgrading to WPA2 encryption is a recommended step as it is currently the most secure encryption protocol for wireless networks. Disabling the SSID broadcasts adds an extra layer of security by making the network invisible to unauthorized users. Using MAC filtering allows only specific devices with pre-approved MAC addresses to connect to the network, further enhancing security. However, upgrading to WEP encryption is not recommended as it is an outdated and easily compromised encryption protocol. Using the default SSID is also not recommended as it can make the network more vulnerable to attacks.Rate this question:
