A wired network is undergoing several changes that could leave it vulnerable to connection by unauthorized devices while the work is in progress. Which two temporary measures would enable the authorized devices to continue to have network access but prevent unauthorized devices from connecting? (Choose two.)
- Disable DNS.
- Disable SSID broadcast.
- Disable DHCP.
- Subnet the network.
- Assign static IP addresses to the authorized devices.
Explanation: Disabling DHCP and assigning static IP addresses only to authorized devices will prevent unauthorized devices from automatically obtaining IP address information. Without the correct IP address information, the unauthorized devices will not be able to communicate over the network. Disabling DNS will result in all connected devices no longer automatically being able to communicate with network resources by name (IP addresses would have to be used.), but will not prevent unauthorized devices from connecting and enabling potentially malicious access from occurring. Subnetting the network will change the range of IP addresses used but not prevent unauthorized network access. Disabling SSID broadcasts is only applicable to wireless networks, not wired networks.
