What purpose would you achieve by enabling the block change tracking feature?() A: Eliminate the necessity for backups. B: Perform optimized image copy backups. C: Perform optimized incremental backups. D: Enable checkpoint (CKPT) to perform checkpointing at every block change. E: Enable database writer (DBWn) to write changed blocks to data files faster.

When scaling Coherence from one to two cache servers, it will not show the same scalability as two to four. Why?() A: Coherence uses a more efficient TCMP algorithm going from two to four cache servers B: When going from one to two cache servers, object backups are copied across servers so work is doubled,but going from two to four is a fixed amount of work C: Near cache is enabled with a larger quorum thus performance is improved D: all of the above
