You want to restrict host access to a wireless access point. What is the best way to do this?

Question

Exhibit

Options

• AEnable MAC address filtering at each host.
• BLog in to the access point and configure features, such as changing the SSID.
• CChange the Direct Sequence Spread Spectrum (DSSS) signal at both the access point and each
• DInstall software on the host you want to limit, then use a Web browser to log in to the host and

• C

• D
  7% (3)

Explanation

Logging into the access point and configuring it (option B) is correct because the access point itself is the central control point for all wireless access - features like MAC filtering, SSID changes, allowed client lists, and encryption are all managed there, making it the authoritative place to restrict who can connect.

Why the distractors are wrong:

• A is backwards - MAC address filtering is configured on the access point, not on individual hosts; hosts don't control their own network admission.
• C is a red herring - DSSS is a physical-layer signal modulation technique, not an access control mechanism, and you can't selectively restrict hosts by changing it.
• D describes an unrelated concept (possibly host-based software management), not a wireless access control method; network access restrictions belong on the network device, not the endpoint.

Memory tip: Think of the access point as the bouncer at the door - you don't restrict entry by talking to the guests (hosts), you configure the rules at the door (AP). Any legitimate access control feature (SSID hiding, MAC filtering, WPA2 passphrases) lives on the AP itself.
