Database Server management Questions needs to be answered.

Need someone who is expert in Database Server Management to answer 4 theoretical engineering questions for me. Each answer needs to be of at least 100 words and should be correct. Need it asap and possibly within next 5 hours. I have attached the .pdf file with questions. Please take a look and bid only if you believe you can answer them all correctly and provide me with the answers within next 5-6 hours. Start your bid proposal with the word 'extemnt' so that I'll know that you have read the project brief. My budget it $40. Bid for anymore and I'll ignore your bid. Ask anymore after accepting the project and I'll file a dispute and give you a negative review for wasting my time. This is a very simple job for someone who is knowledgeable. Serious bidders and professionals only.
