If you have many lists like this you can define a new list environment: Aenumerate, after you've added this code to your preamble:

\usepackage{enumitem}
\newlist{Aenumerate}{enumerate}{1}
\setlist[Aenumerate]{label=A.\arabic*}

Otherwise, simply load enumitem and use this code in the body of your document:

\begin{enumerate}[label=A.\arabic*]
\item ...
   ⋮
\end{enumerate}
