E.The ADDM calls other advisors if required, but does not provide recommendations about the advisors.

Answer: BC

答案解析：

ADDM 在記錄每個(gè)AWR 快照之后會(huì)自動(dòng)運(yùn)行。每次記錄快照后，ADDM 會(huì)分析與最后兩個(gè)快照對(duì)應(yīng)的時(shí)段。ADDM 會(huì)預(yù)先監(jiān)視實(shí)例，以便在大多數(shù)瓶頸問題成為嚴(yán)重問題之前檢測(cè)到這些問題。多數(shù)情況下，ADDM 會(huì)為檢測(cè)到的問題提供建議解決方案，甚至可以量化這些建議的優(yōu)勢(shì)。
