Are there any potential issues with TrueCopy Synchronous solutions?
How many independent replicated copies can be made from one TrueCopy P-Vol?
a. 1; b. 3; c. 9; d. 32

Ports for sending TrueCopy traffic are Ports
Ports for receiving TrueCopy traffic are Ports
If you were configuring TrueCopy for redundancy, what would be the minimum
number of connections you should configure? Fiber connections
Ports on the MCU
Ports on the RCU
Once the ports are configured, add the RCU logical links between the MCU and RCU

Requirement: Customer needs to fail-back to production (replicate data back to the
production site) as well as fail-over to the DR site in the event of a disaster.
Configure the MCU and RCU TrueCopy Paths to support this -
On the above diagram, use your WebEx drawing tools to draw the connections
between the MCU and RCU (account for redundancy)
