**Question 1.** Which replication model guarantees that the secondary site always contains an
exact copy of the primary data at the moment of the write operation?
A) Asynchronous replication
B) Near‑synchronous replication
C) Synchronous replication
D) Periodic snapshot replication
Answer: C
Explanation: Synchronous replication waits for acknowledgment from the secondary storage
before completing the write, ensuring zero data loss at the point of failure.
**Question 2.** In Hitachi replication terminology, what does “in‑system replication” refer to?
A) Replication between two geographically distant data centers
B) Replication that occurs within the same storage controller enclosure
C) Replication that uses IP over Ethernet links only
D) Replication that creates full clones on a separate array
Answer: B
Explanation: In‑system replication (e.g., ShadowImage, Thin Image) copies data within the same
storage system, providing point‑in‑time copies without leaving the enclosure.
**Question 3.** Which Hitachi product creates full‑volume clones that can be used for rapid
provisioning of test environments?
A) Hitachi Thin Image (HTI)
B) Hitachi ShadowImage (SI)
C) Hitachi Universal Replicator (HUR)
D) Hitachi TrueCopy (TC)

Answer: B
Explanation: ShadowImage creates full‑volume clones (also called “full clones”) that are
independent writable copies of the source volume.
**Question 4.** When would you choose Hitachi Thin Image over Hitachi ShadowImage?
A) When you need a full, independent clone for a production workload
B) When you need space‑efficient point‑in‑time snapshots with shared data blocks
C) When you need synchronous replication across a 10 km distance
D) When you need to replicate across heterogeneous storage platforms
Answer: B
Explanation: Thin Image provides snapshot‑based, space‑efficient copies that share unchanged
blocks with the source, ideal for backup or test scenarios.
**Question 5.** Which command creates a replication pair in the CCI (Command Control
Interface) environment?
A) paircreate
B) pairresync
C) pairsplit
D) pairevtwait
Answer: A
Explanation: The **paircreate** command establishes a new replication relationship (pair)
between primary and secondary volumes.
**Question 6.** In a HORCM configuration file, which directive defines the name of a storage
instance?
A) instance_name
, [HCE5710] HCE 5710 Hitachi Vantara Certified

Certification Review Guide
B) storage_id
C) device_group
D) host_name
Answer: A
Explanation: The **instance_name** parameter in horcm.conf identifies the logical storage
instance that HORCM will manage.
**Question 7.** What is the purpose of a Consistency Group (CTG) in Hitachi replication?
A) To aggregate multiple hosts into a single HBA group
B) To ensure that a set of volumes are replicated at the same point‑in‑time
C) To provide load balancing across network paths
D) To encrypt data before replication
Answer: B
Explanation: A Consistency Group guarantees that all member volumes are synchronized
together, preserving application‑consistent snapshots across the group.
**Question 8.** Which of the following is a requirement for configuring Hitachi TrueCopy (TC)
synchronous replication?
A) Minimum distance of 200 km between sites
B) Dedicated Fibre Channel links with latency < 5 ms
C) Use of a journal volume on the secondary side
D) Only IP‑based connections are supported
Answer: B
Explanation: Synchronous TC requires low‑latency links (typically < 5 ms) often achieved with
dedicated FC connections; longer distances would degrade performance.

**Question 9.** Hitachi Universal Replicator (HUR) primarily uses which mechanism to achieve
asynchronous replication?
A) Real‑time block mirroring
B) Periodic full‑volume copies
C) Journaling of changed blocks
D) Continuous data protection (CDP) snapshots
Answer: C
Explanation: HUR writes changes to a journal volume on the primary side, which are later
transferred to the secondary site, enabling asynchronous replication.
**Question 10.** In a 3‑Data Center (3DC) topology, which component is responsible for
cascading replication from Site A to Site C via Site B?
A) Primary‑only journal volume
B) Multi‑target TrueCopy pair
C) HUR “cascade” configuration
D) Global‑Active Device (GAD) quorum disk
Answer: C
Explanation: HUR supports cascade replication where Site B receives journal data from Site A
and forwards it to Site C, forming a chain of asynchronous replication.
**Question 11.** Which storage‑side object represents a secondary volume in a TrueCopy pair?
A) P‑VOL
B) S‑VOL
C) C‑VOL
