Answer :
To solve this problem, we must identify which action aligns with methods often used in IT security attacks to disrupt wireless network connectivity.
Let's go through each option:
Continually sending CTS frames: Clear-to-send (CTS) frames are part of the request-to-send/clear-to-send (RTS/CTS) protocol used to reduce collisions on a wireless network. By continually sending CTS frames, attackers can effectively prevent other devices from accessing the network by falsely indicating that the network is in use, which is known as a CTS flood attack.
Temporarily modifying the initialization vector: Initialization vectors are used in encryption protocols like WEP to provide randomness. While modifying them could cause some security issues, it wouldn't typically prevent access to a wireless network.
Generating strong jamming signals: This method involves sending disruptive signals to interfere with WiFi communication. However, this is a physical interference method rather than a logical one.
Tampering with the shared secret key: This could cause authentication issues but isn't commonly a method to prevent ongoing connections unless the key is changed or blocked.
Spoofing certain types of management frames: Management frame spoofing involves manipulating frames that manage network connections. This could be used for attacks like deauthentication, which prevent devices from staying connected.
Given these explanations, the most probable action being taken by learners to prevent access to the network is 'a. They are continually sending CTS frames.' This aligns with methods used to disrupt network access by occupying available bandwidth with fake traffic, thus preventing legitimate connections.
