NEW QUESTION # 160
What is a benefit of differential backup over incremental backup?
- A. Incremental backup can expand to contain more data than differential backup.
- B. Differential backups have longer restore times than incremental backup.
- C. Differential backup can expand to contain more data than an incremental backup
- D. Incremental backups determine the backup copy used to restore the data.
Answer: C
Explanation:
Explanation
Differential backups are more efficient than incremental backups because, instead of backing up only the changes made since the last backup, they back up all of the data that has changed since the last full backup.
This means that, unlike incremental backups, the size of the differential backup is not limited and can expand to contain more data than an incremental backup. Additionally, differential backups are faster to restore since they only need to read the differential backup and last full backup, rather than all of the incremental backups.
NEW QUESTION # 161
What provides the ability to automatically relocate extents across physical storage drives over the entire pool when new drives are added to the pool?
Response:
- A. Automated extent tiering
- B. Extent relocation

Answer: C
NEW QUESTION # 162
What statement describes machine learning?
- A. Replicating a detailed process and then implementing it in software
- B. Applies an algorithm to large amounts of data for pattern discovery
- C. Developing a program to compute every possible outcome
- D. Organizes data efficiently so that compute systems can learn
Answer: B
Explanation:
Explanation
Machine learning is a subfield of artificial intelligence that gives computers the ability to learn without explicitly being programmed [1]. It does this by applying an algorithm to large amounts of data in order to discover patterns and insights that can be used to inform decisions and predictions. This allows machines to learn from experience and make decisions in a way that mimics the human brain.
