For which three reasons were circuit-switched, connection-oriented technologies rejected when the Internet was being developed? (Choose three.)

For which three reasons were circuit-switched, connection-oriented technologies rejected when the Internet was being developed? (Choose three.)

• Circuit-switched technologies required that a single message be broken up into multiple message blocks that contain addressing information.
• Early circuit-switched networks did not automatically establish alternative circuits in the event of circuit failure.
• Circuit-switched technologies required that an open circuit between network endpoints be established, even if data was not actively being transferred between locations.
• The quality and consistency of messages transmitted across a connection-oriented, circuit-switched network cannot be guaranteed.
• The establishment of multiple, simultaneous open circuits for fault tolerance is costly.
