You need to monitor the health of your tables and indexes in order to implement the required index maintenance strategy.
What should you do?
A. Query system DMVs to monitor avg_chain_length and max_chain_length. Create alerts to notify you when these values converge.
B. Create a SQL Agent alert when the File Table: Avg time per file I/O request value is increasing.
C. Query system DMVs to monitor total_bucket_count. Create alerts to notify you when this value increases.
D. Query system DMVs to monitor total_bucket_count. Create alerts to notify you when this value decreases.
