ITPEC IP April 2025 Question 33

Topic: Networks

Mr. A sent an e-mail to the three (3) people Mr. P, Mr. Q, and Mr. R. He entered Mr. P’s e-mail address in the To field, Mr. Q’s e-mail address in the CC field, and Mr. R’s e-mail address in the BCC field. Which of the following is the appropriate description concerning the three (3) recipients of the e-mail?

Explanation

Mr. Q can see that the e-mail was also sent to Mr. P — To and CC addresses are shown to every recipient, BCC addresses to nobody.

Every recipient, Mr. P, Mr. Q and Mr. R alike, sees the header "To: Mr. P" and "CC: Mr. Q". The BCC field is removed from the delivered message, so Mr. P and Mr. Q cannot see that Mr. R received it; Mr. R knows only that he himself got a copy.

Answer (c)

Why not others:

  • •(a) — Mr. R is a BCC recipient, hidden from Mr. P and Mr. Q
  • •(b) — Mr. Q is in CC, which Mr. P sees
  • •(d) — Mr. R sees the To and CC fields, so he knows the e-mail also went to Mr. P and Mr. Q

Key rule: To is for the people expected to act, CC for those kept informed, and BCC for copies whose addresses must not be revealed to the other recipients.
