C++11 inheriting constructors and access modifiers

Question

Assuming the following layout:

class Base
{
protected:
    Base(P1 p1, P2 p2, P3 p3);

public:
    virtual void SomeMethod() = 0;
}

class Derived : public B         


        

Answer 1

According to 12.9/4, "Inheriting constructors", when saying using X::X,

A constructor so declared has the same access as the corresponding constructor in X.

So the inherited constructor is also protected.
