A team of programmers is involved in reviewing a proposed design for a new utility class. After some discussion, they realize that the current design allows other classes to access methods in the utility class that should be accessible only to methods within the utility class itself.
What design issue has the team discovered?（）

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？（）  Two independent copies of the data can be created and synchronized using the "HACMP/XD：HAGeo"。  The existing disks can be incorporated a single storage unit using the optional product "HACMP/XD：PPRC"。  AIX can create a mirrored logical volume across the two systems that would be accessible from either system。  AIX can use the multi path IO subsystem to spread the information across the devices and keep the copies separated。 以下原则中属于资产评估的经济原则的是（）。 贡献原则。 科学性原则。 专业性原则。 客观性原则。 There is the possibility that hdisk1 in the root volume group is going bad.
