In step 4 of the CSMA/CA protocol, a station that successfully transmits a frame begins the CSMA/CA protocol for a second frame

at step 2, rather than at step 1. What rationale might the designers of CSMA/CA have had in mind by having such a station not transmit the second frame immediately (if the channel is sensed idle?

Answer:

There could be a collision if a hidden node problem occurs.

Explanation:

CSMA/CA(carrier sense multiple access/ collision avoidance) is a multiple access method in wireless networking, that allows multiple node to transmit. Collision avoidance of this method is based on preventing signal loss or downtime as a result of collision of transmitting multi signals.

If a node at step 4(transmit frame) sends the first frame, the node still needs to send a RTS(request to send) and to receive a Clear to send (CTS) from the WAP, the is to mitigate the issue of hidden node problem as all frame are treated as unit, so other listening nodes, not detected would seek to connect and transmit as well.

Andrei [34K]

Answer: C)definition of empirical measures

Explanation: CSIRT(Computer Security Incident Response Team) is the team that is related with the taking the measurement according to the related incident of the security. The tasks that are performed by the team are detection of security error, dealing with it ,introducing ideas to resolve it etc.

Empirical measure is the measure that technique which has randomness. Random measures are the based on the possible methods that can be used for solving the security issue.Thus feedback of CSIRT is effective or not can be seen by the empirical technique.Thus, the correct option is option(c).
