Subject – verb agreement and the parenthetical phrase

Which is correct? Easy administration, as well as greater security, ___ expected when you install an IP surveillance system. a. is b. are

Answer: a.

Explanation: The part between commas is a parenthetical phrase — ignore it when you’re identifying the subject. Administration is the subject in this sentence, so that’s what the verb has to agree with.
