Select all that applyMedium

Catch specific exception types that you can actually handle.Using exceptions to exit loops in normal flow is a good practice.`catch (HttpRequestException e) when (e.StatusCode == HttpStatusCode.NotFound)` is an exception filter.Exception filters run before the stack is unwound.An empty `catch { }` block is a safe default.

Answer and explanation

Correct answer

A. Catch specific exception types that you can actually handle.
C. catch (HttpRequestException e) when (e.StatusCode == HttpStatusCode.NotFound) is an exception filter.
D. Exception filters run before the stack is unwound.

Why

Exception filters (when) let you decide whether to catch without unwinding the stack. If the filter returns false, the stack (and debugger context) is preserved for outer handlers.
