Hitachi Vantara Certified Expert - Replication Solutions Architect HCE-3710 Prüfungsfragen mit Lösungen
Frage #1
How does distance between sites affect host response time when using asynchronous replication?
Response:
A. Host response time decreases with increased distance.
B. Host response time is unpredictable with increased distance
C. Host response time is not affected by increased distance.
D. Host response time increases with increased distance.
Frage #2
On a Virtual Storage Platform, a customer wants to create a daily in-system replication copy of a database. They want to retain each copy for 90 days. Which product is required?
Response:
A. Hitachi ShadowImage
B. Hitachi Dynamic Replicator
C. Hitachi Copy-On-Write
D. Hitachi Thin Image
Frage #3
A customer is using ShadowImage(SI) on a Virtual Storage Platform (VSP) for a point-in-time copy. The SI P-Vol resides in a SAS HDP pool and the SI S-Vol resides in a SATA HDP pool. During resychronization, the VSP cache write pending hits 60 percent utilization in CLPRO.
What are two ways to reduce the resynchronization impact on host performance?
(Choose two.)
Response:
A. Run an SI quick split.
B. Run an SI resync during non-peak hours.
C. Keep the SI pairs in PAIR state.
D. Put the SI S-Vols in a separate CLPR.
Frage #4
Which statement accurately describes RTO?
Response:
A. RTO is the period of time after an outage in which the systems and data must be restored to the RPO
B. RTO is the amount of data which must be restored to the predetermined RPO after an outage.
C. RTO describes the age of the data you want the ability to restore in the event of a disaster.
D. RTO indicates the time required to recover or fail over network operations.
Frage #5
Which sizing metric is directly affected by the peak write MB/sec measurement provided by the workload analysis?
Response:
A. telecommunication bandwidth
B. cache
C. shared memory
D. selection of DWDM or IP-based connectivity
