  Radio frequencies for Wi-Fi

  Types of modem

  Wireless security protocols

  Brands of Wi-Fi

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

  TRUE

  FALSE

 3. What does WPA stand for?

  Wi-Fi Purchase Accreditation

  Wireless Protocol Agreement

  Web Personal Access

  Wi-Fi Protected Access

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

  512-bit

  256-bit

  64-bit

  128-bit

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

  Advanced Encryption Standard (AES)

  Secure Wi-Fi Encoding (SWE)

  Limited Portal Selection (LPS)

  Improved Security Access (ISA)

 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 signal marker (WSM)

  wireless identification flag (WIF)

  service set identifier (SSID)

  router digital label device (RDLD)

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

  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

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

  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.

  TRUE

  FALSE

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

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

  The MAC address contains the Wi-Fi password

  MAC addresses can be spoofed

  MAC addresses are easy to guess
