  Radio frequencies for Wi-Fi

  Wireless security protocols

  Brands of Wi-Fi

  Types of modem

 2. WEP offers relatively poor security and is no longer supported by the Wi-Fi Alliance.

  TRUE

  FALSE

 3. What does WPA stand for?

  Web Personal Access

  Wi-Fi Purchase Accreditation

  Wi-Fi Protected Access

  Wireless Protocol Agreement

 4. WPA generally uses a ___ pre-shared key.

  512-bit

  128-bit

  256-bit

  64-bit

 5. WPA was succeeded by WPA2. WPA2 offers better security as it supports ______ ______ ______.

  Secure Wi-Fi Encoding (SWE)

  Improved Security Access (ISA)

  Limited Portal Selection (LPS)

  Advanced Encryption Standard (AES)

 6. An advantage of WPA2 is that it has no known security flaw.

  TRUE

  FALSE

 7. Routers usually broadcast the 'name' of the Wi-Fi network by default (e.g. 'Guest Wi-Fi'). The technical term for the name of a network is the …

  wireless identification flag (WIF)

  router digital label device (RDLD)

  service set identifier (SSID)

  wireless signal marker (WSM)

 8. Most routers allow this broadcast to be disabled. Why would doing this improve the security of the network?

  A hacker would need to find out both the network 'name' and the password to access the WLAN

  It will be impossible for someone not already connected to the WLAN to join the network

  It will improve the encryption of the Wi-Fi password

  It activates a virtual firewall that monitors network traffic

 9. A MAC (Media Access Control) address whitelist is a list of approved MAC addresses that are allowed to connect to a network.

  FALSE

  TRUE

 10. Why would a whitelist provide little protection against a sophisticated Wi-Fi hacker?

  MAC addresses are easy to guess

  The MAC address contains the Wi-Fi password

  It is straightforward to add an address to the router's whitelist

  MAC addresses can be spoofed
