单项选择题Company.comhasdecidedtoimplementVPNforallnetworktraffic.HowmightthismightaffectHACMP？（）

A. Only the heartbeat IP network can exist in a VPN style network.
B. HACMp must have separate VPN’s for all ’non-service’ and ’service’ adapter networks.
C. If a VPN is used for IP traffic the heartbeating must be done over disk connections.
D. HACMP can exist in a VPN network environment，but special considerations must be addressed.

A. Assume the system was stopped by a failure.
B. Ensure the hostname parameters is set correctly.
C. Assume the system was stopped by a graceful shutdown.
D. Mount all volumes and file systems before running the application.

单项选择题Due to a recent change in government regulations， Company.com needs to create two  independent but synchronized copies of their data. These copies must be contained in separate storage device a minimum of 100 km apart. The customer has capacity in two systems that meet the criteria， one with SSA disk and the other is FAStT.  What facility can be used to manage this issue？（）

A. Two independent copies of the data can be created and synchronized using the "HACMP/XD：HAGeo"
B. The existing disks can be incorporated a single storage unit using the optional product "HACMP/XD：PPRC"
C. AIX can create a mirrored logical volume across the two systems that would be accessible from either system
D. AIX can use the multi path IO subsystem to spread the information across the devices and keep the copies separated
