The technician should change the default administrative password FIRST to ensure the

default administrative password is a basic security measure that can help prevent
unauthorized access to the network equipment. Locking all devices in a closet is a physical
security measure that can help prevent theft or damage to the devices, but it does not
address external threats on the Internet. Ensuring all devices are from the same
manufacturer is not a security measure and does not address external threats on the
Internet. Installing the latest operating system and patches is important for maintaining the
security of the network equipment, but it is not the first action the technician should take.
