- MAC address filtering
-
What is the primary effect of disabling SSID broadcast on a wireless access point?
- Blocks unauthorised devices
- Encrypts transmitted data
- Hides network name
- Increases transmission speed
-
What is the primary function of a Service Set Identifier (SSID) in wireless networking?
- Filters MAC addresses
- Identifies the network
- Prevents packet collisions
- Encrypts network data
-
How does a MAC address allow list secure a wireless network?
- Encrypts transmitted packets
- Prevents signal interference
- Hides network name
- Restricts specified hardware
-
Why is the CSMA/CA protocol used on wireless networks rather than CSMA/CD?
- Speeds up transmission
- Detects packet collisions
- Avoids packet collisions
- Encrypts wireless traffic
-
Which problem in CSMA/CA does the RTS/CTS protocol exchange address?
- MAC address spoofing
- Hidden node problem
- Eavesdropping risk
- Weak data encryption
-
Which measure provides strong encryption for data transmitted over a wireless network?
- CSMA/CA
- SSID disabling
- WPA2
- MAC filtering
-
Which device allows client hardware to connect to a wireless access point?
- Modem bridge
- Router firewall
- Ethernet switch
- Wireless network adapter
-
Why is MAC filtering used alongside WPA2 encryption on a wireless network?
- Increases bandwidth limit
- Encrypts transmitted data
- Restricts network access
- Hides network SSID
-
What hardware component must be added to a desktop PC lacking built-in WiFi capability?
- Wireless access point
- Network router
- Wireless network adapter
- Ethernet switch
-
Which feature is NOT an established wireless network security measure?
- MAC allow list
- WPA2 encryption
- Disabled SSID broadcast
- Barcode identification
-
What is the main role of a Wireless Access Point on a local network?
- Assigning IP addresses
- Filtering MAC addresses
- Providing physical cabling
- Broadcasting wireless signal
-
What is the main drawback of using CSMA/CA without enabling RTS/CTS?
- Data packet corruption
- Hidden node collisions
- Reduced signal range
- Unencrypted transmissions
-
Which security measure blocks a device with the correct password if its hardware address is unapproved?
- MAC allow list
- Disabled SSID
- RTS/CTS protocol
- WPA2 encryption
-
Why is disabling SSID broadcast considered an incomplete security measure?
- Passcode is disabled
- MAC addresses change
- Data becomes corrupted
- Traffic reveals name
-
What does the WPA in WPA2 stand for?
- Wireless Packet Authentication
- Wired Protected Architecture
- WiFi Protected Access
- WiFi Public Access
-
Why are wireless signals more vulnerable to eavesdropping than wired connections?
- Bandwidth is lower
- Radio waves spread
- Signals travel faster
- MAC addresses leak
