IPA IP 2020 Question 92
A question IPA Japan published in 令和2年度 10月 ITパスポート試験 公開問題 問92, translated into English. ITPEC is based on the same exams.
When Mr. A sends an e-mail addressed to Mr. X, he has decided to also send it to Mr. Y and Mr. Z for reference. However, he does not want Mr. X and Mr. Y to know that it was sent to Mr. Z. Which of the following is an appropriate combination of destinations to be specified in this case?
Explanation
To: X, Cc: Y, Bcc: Z — each recipient goes in the field that matches their role, and the one to be hidden goes only in Bcc.
- •To — the addressee the mail is meant for: Mr. X. Every recipient sees this field.
- •Cc — copies sent for reference, also visible to every recipient: Mr. Y, whom nobody needs to hide.
- •Bcc — copies whose addresses are removed from what the other recipients receive: Mr. Z, so that Mr. X and Mr. Y cannot see that he got it.
An address hidden in Bcc must not appear in To or Cc as well, or it shows anyway.
Answer (a)
Why not others:
- •(b) — puts Mr. Z in Cc as well as Bcc, so Mr. X and Mr. Y see his address in Cc
- •(c) — swaps the two: Mr. Z in Cc is visible to both, and Mr. Y is hidden although nobody asked for that
- •(d) — puts Mr. Z (and Mr. Y) in To, where everyone sees them
Key rule: To and Cc addresses are visible to every recipient; only an address entered in Bcc alone is hidden from the others.
