A network administrator needs to connect the main bank office to two branch offices. During
business hours, the bank requires a redundant connection to maintain connectivity between the
branch offices and the main bank. The primary connection to the branch offices should be cost
effective and provide at least 512 kbps dedicated access to the branch offices. The backup
connection should only be used when the primary connection goes down. Also, the backup
connection should have a relatively short setup time, and provide 128 kbps of bandwidth. Which
combination of technologies meets these requirements?
