大全20-9

大全-20-9. Mannis Corporation’s archival records are stored in an obsolete format that is accessible only by its current computer system; thus they are inaccessible when that system is not functioning properly. In order to avoid the possibility of losing access to their archival records in the case of computer malfunction, Mannis plans to replace its current computer system with a new system that stores records in a format that is accessible to several different systems.
The answer to which of the following questions would be most helpful in evaluating the effectiveness of the plan as a means of retaining access to the archival records?
(A) Will the new computer system require fewer operators than the current system requires?
(B) Has Mannis Corporation always stored its archival records in a computerized format?
(C) Will the new computer system that Mannis plans ensure greater security for the records stored than does Mannis’ current system?
(D) Will Mannis’ current collection of archival records be readily transferable to the new computer system?
(E) Will the new computer system be able to perform many more tasks than the current system is able to perform?
ans:D
不好意思,問個 老題,想請問D選項中新舊系統可以相互轉換是關鍵嗎?
我選C,是否新系統比較上有更高的 安全性??錯在哪? 謝謝指教

我也是選C

D關於舊系統容不容易轉換到新系統怎會是問題? 不容易克服就好了,
只要可以確保資料安全,這不是它題目要的目地嗎??~~~~

重點：Mannis Corporation’s archival records are stored in an obsolete format that is accessible only by its current computer system

他說...這個資料格式(舊系統)...只能有舊系統自己能讀取...

現在要轉換成新的....

C的選項很誘人....但...他是第二順位的考量!!!

D卻是必須的...轉換不過去...新的系統穩不穩定就不重要了~

言之有理
