Explanation:
Box 1: NOINDEX
NOINDEX specifies that intensive checks of nonclustered indexes for user tables will not be performed. This choice decreases the overall execution time.
NOINDEX doesn't affect system tables because integrity checks are always performed on system table indexes.
Box 2: PHYSICAL_ONLY
Many new checks have been introduced to include the new features.
Therefore, using the PHYSICAL_ONLY option may cause a much shorter run-time for DBCC CHECKDB on large databases and is recommended for frequent use on production systems.
