HP0-J67 Question #91: Real Exam Question with Answer & Explanation
The correct answer is D. replication type (if set to synchronous. set it to asynchronous periodic). A customer is experiencing a sudden and significant decrease in write performance on their primary HP 3PAR array, while read performance remains unaffected.
Optimizing and Managing Multi-site Storage
Question
A customer experiences a sudden loss in write performance on the HP 3PAR StoreServ array on the ficantly. What should you advise the customer to check primary site. Reads are not affected, but writes slowed down signi first in order to solve the issue?
Options
- Areplication type (if set to asynchronous periodic, set it to synchronous)
- BFibre Channel infrastructure and optical cabling for malfunctioning components
- Chost multi-pathing software (update it to the newest available version)
- Dreplication type (if set to synchronous. set it to asynchronous periodic)
Explanation
A customer is experiencing a sudden and significant decrease in write performance on their primary HP 3PAR array, while read performance remains unaffected.
Common mistakes.
- A. Changing from asynchronous periodic to synchronous replication would worsen write performance, as synchronous replication introduces latency from the secondary site into every primary write operation, exactly the opposite of the desired effect.
- B. While Fibre Channel infrastructure issues can affect performance, if only writes are impacted and reads are fine, the issue is less likely to be a general Fibre Channel link problem and more likely related to replication synchronization.
- C. Updating host multi-pathing software is a general maintenance task and unlikely to be the first check for a sudden, specific write performance degradation related to replication, especially when reads are unaffected.
