CompTIA A+ 220-1102 Practice Question

Changing the default passwords for network devices is crucial because default passwords are typically well-known and easily accessible, making the device vulnerable to unauthorized access. Updating the password to a strong, unique one reduces the risk of unauthorized access significantly. Changing the Service Set Identifier (SSID) and updating the firmware are also good practices but do not address the immediate vulnerability posed by default passwords. Keeping default device names does not affect security as significantly as unaltered default passwords.
