SSH (Secure Shell) is a protocol that would most likely be implemented to encrypt data in transit for remote administration. SSH provides secure communication between two devices over an unsecured network by using public-key cryptography and symmetric encryption. SSH can be used to remotely execute commands, transfer files, or tunnel other protocols. Telnet, TFTP, and rlogin are protocols that do not encrypt data in transit and are considered insecure for remote administration. References: [CompTIA Server+ Certification Exam Objectives], Domain 2.0: Networking, Objective 2.4: Given a scenario involving network security/access methods, implement an appropriate solution.

A microSD card is the best method to stage the new media for the default boot device of a remote embedded IoT server that is having a Linux OS upgrade installed. A microSD card is a small and portable storage device that can store large amounts of data.
