問題2

In package tracking systems, read-only tags are unable to be used because the destination postal code is not contained within the tag. Read-only tags have been proposed to work in a manner so as to read the read-only tag and then access the package tracking company's database to determine the appropriate sorting, based on the postal code within the database. Which of the following would be a reason that this would not be successful?

A. Read-only tags are not able to be reused and re-write tags can be re-used.

B. When recording the destination information at package pickup it is feared that the wrong postal code will be entered.

C. Using a reference number instead of the postal code for sorting depends upon a communications link that is not completely reliable.

D. Distribution of the read-only tags to the drivers requires that each driver have a specific sequence of numbers in the tag.

正確答案: C

問題3
