Hitachi Vantara HCE-5700 (Block Storage Solutions Implementation) Sample Questions:

01. Users of an application on a VSP 5000 report brief, repeated latency stalls lasting a second or two. The Analyzer dashboard, which summarizes data at a minute-level interval, shows response time and port utilization as normal across every window examined. The integrator is confident the stalls are real.
What is the correct next diagnostic step?
a) Enable granular, second-level data collection so a sub-minute spike, such as a brief port or processor saturation, is captured instead of being averaged away.
b) Conclude that the array is not the cause, because every monitored metric sits within range at the dashboard's minute-level reporting interval.
c) Increase cache allocation to the affected volumes, since brief stalls are always caused by a cache shortage.
d) Open a capacity forecast report to determine whether the pool will exhaust its free space in the near future.
 
02. Before go-live, a customer insists the integrator prove one specific thing: that no single host access path can become a point of failure. Several readiness tests are scheduled.
Which test answers precisely that question?
a) A controlled failover test of the active-active controllers
b) A verification of host multipathing across redundant paths
c) A performance benchmark run under a representative production workload
d) A pool-utilization review to confirm headroom before production load
 
03. Using Ops Center Administrator, an integrator provisions and attaches a new volume to a server, but the job fails. Investigation shows the LU number selected for the new volume is already in use by another volume presented to the same server.
What is the correct way to resolve this and complete the attachment?
a) Enable automated SAN zoning so the fabric reassigns the LU number automatically.
b) Delete the existing volume that holds the LU number and then recreate both volumes.
c) Restart the Administrator service and resubmit the job with more parallel tasks.
d) Assign the volume an unused LU number using Add LUs to Host Groups.
 
04. Several unrelated production volumes provisioned from the same thin-provisioned pool all begin failing writes at the same moment, even though each volume is far below its own presented capacity. Virtualization hosts report their datastores as out of space.
What is the most likely cause?
a) The pool's wide striping has concentrated all writes onto a single failing drive group.
b) Host multipathing lost one path, so writes queue until the datastores report full.
c) The shared pool has exhausted its physical capacity, so every volume drawing from it loses the ability to allocate new blocks.
d) One volume reached its presented logical size, and the array propagated that volume's out-of-space error to the other volumes sharing the pool.
 
05. During integration a new volume has been provisioned on the VSP, and Fibre Channel zoning between the host HBAs and the array ports has been verified as correct on both fabrics. The host still does not see the new LUN.
What is the most likely cause?
a) The host HBA firmware is fundamentally incompatible with Fibre Channel
b) The volume has not been mapped to the host on the array, or the host has not rescanned
c) Host multipathing software has not been installed, which is hiding the LUN
d) More zoning is needed, so add additional zones for the same ports on the fabric switches
 
06. An unresolved performance problem on a VSP 5000 is about to be escalated to the Global Support Center. The integrator wants the case to be actionable on first contact rather than generating an immediate request for more information.
Which two steps best prepare the escalation?
(Choose two.)
a) Expand the affected pool with additional drives first, so the problem is already mitigated when support engages.
b) Include a baseline from a period of acceptable performance alongside the current metrics, so the degradation can be quantified.
c) Omit the current configuration details, since the support center can retrieve the array's settings on its own.
d) Replace the controller board that shows the highest utilization before opening the case, to shorten the overall resolution time.
e) Capture the specific time window in which the problem occurs, so the collected data can be correlated to the symptom.
 
07. While investigating a slow volume, the integrator finds a service information message (SIM) and matching event-log entries indicating that a back-end hardware component has actually failed.
Which diagnostic path is correct?
a) Open a capacity forecast to check whether the failure was caused by the pool approaching its space limit.
b) Ignore the SIM as a false positive and restore performance by moving the volume to a different pool.
c) Treat it as a performance-tuning exercise and begin locating a bottleneck along the I/O path using granular, second-level metrics before considering the hardware.
d) Treat it as a hardware fault: act on the SIM and event-log evidence and route the repair through the authorized Hitachi Vantara service process.
 
08. Hosts attached to a VSP 5000 report high latency only during a nightly batch job. Granular data collected during the window shows the front-end port serving those hosts running at near saturation, while back-end drive and media utilization stay low and pool free space is ample.
Which two conclusions are supported?
(Choose two.)
a) The bottleneck is on the front-end path, at the saturated port, not at the media.
b) The media is the constraint, so moving the volumes to faster drives will resolve the stalls.
c) The pool is approaching an out-of-space condition and must be expanded immediately.
d) A back-end component has failed and should be replaced through the service process.
e) Adding drives or pool capacity would not relieve the latency, because the constrained resource is the port.
 
09. Two application servers must both actively read and write the same block LUN presented from a VSP at the same time, as an active/active cluster. The integrator has zoned and masked the LUN and both servers can see it.
Which two conditions are required for safe concurrent access to that single LUN?
(Choose two.)
a) Automated tiering enabled on the pool so hot blocks move to faster media
b) A cluster-aware file system or host clustering that coordinates concurrent writes
c) A separate LUN masked to only one server so the volume is never shared
d) The one LUN mapped identically to both hosts with multipathing on each
 
10. After integrating a host to a VSP 5000 the volume is visible through multipathing and all paths are healthy, but the application's small random I/O shows higher latency than expected while the array's own ports, processors and media all read lightly loaded.
Which host-side integration setting is the most appropriate first thing to examine?
a) The thin-provisioning pool's subscription ratio, since an over-subscribed pool raises per-I/O latency for its volumes.
b) The fabric zoning, because a volume reachable on too many zones divides each operation's latency budget.
c) The array's RAID level, because small random I/O always requires changing the parity geometry after integration.
d) The host HBA queue depth, since a value set too low throttles outstanding I/O and inflates latency even when the array is not busy.
