A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?
- to restrict access to the WLAN by authorized, authenticated users only
- to monitor the operation of the wireless network
- to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range
- to reduce the risk of interference by external devices such as microwave ovens
A network administrator is configuring a WLAN. Why would the administrator change the default DHCP IPv4 addresses on an AP?
- to eliminate outsiders scanning for available SSIDs in the area
- to reduce the risk of unauthorized APs being added to the network
- to reduce outsiders intercepting data or accessing the wireless network by using a well-known address range
- to reduce the risk of interference by external devices such as microwave ovens
Explanation: Changing default DHCP IPv4 addresses is a fundamental security best practice because default IP ranges and management addresses for wireless routers are well-known and easily found on the internet, meaning that using a non-default range makes it more difficult for unauthorized outsiders to identify the network's structure or gain access to the device's management interface.
