Which is more accurate, A1C or fasting glucose?
Both are accurate. A1C gives the control for 3 months whereas fasting glucose will give the results for that particular day.

Yes, it is possible.
It is possible to have high A1C levels without diabetes in rare cases. Iron, folate etc can also increase HBA1C levels.
The best time would be in the morning or evening.
It can be done at anytime before or after meals.
Fasting blood sugar (in the morning, before eating) should be Less than 100 mg/dL. 1-2 hours after a meal should be Less than 140 mg/dL. And 2-3 hours after eating should be Less than 100 mg/dL
