The correct answer is A. Row size is too large to fit into a single block during insert operations. B. Row moves from one data block to another data block because the row grows too large to fit in C. The table is subject to frequent insert, update, and delete DML activity leading to sparsely. See the full explanation below for the reasoning.
Question
To investigate the slow response time of queries on the TRANS table, you gathered the table statistics and executed the query:
The table is stored in a tablespace that has Automatic Segment Space Management (ASSM) enabled. The tablespace is created with a standard block size of 8192 bytes. Which three can be reasons for the slow response time of the queries? (Choose three.)
Exhibit
Options
- ARow size is too large to fit into a single block during insert operations.
- BRow moves from one data block to another data block because the row grows too large to fit in
- CThe table is subject to frequent insert, update, and delete DML activity leading to sparsely
- DThe value of PCTUSED is set to a value lower than the default, causing row changing.
- EThe value of PCTFREE is set to a value lower than the default, causing row chaining.
