01. While configuring the Fibre Channel ports that connect HNAS file nodes to the back-end array, an implementer is unsure which settings actually apply to an FC port.
Which settings are the relevant ones to tune on an FC port?
a) Link speed and port type/topology
b) Snapshot schedule and retention
c) SMB signing and NFS export options
d) IP address and MTU
02. HNAS offers both read-only snapshots and WORM (immutable) file systems as retention-related controls. Which statement correctly distinguishes them?
a) A WORM file system is a scheduled copy, while a snapshot blocks all writes permanently
b) Snapshots replace backups, while WORM file systems replace replication
c) Snapshots and WORM file systems are two names for the same feature
d) Snapshots are point-in-time recovery copies, while a WORM file system makes its data immutable for a retention period
03. Two EVSs on the same cluster must serve two separate Active Directory forests, and users in the second forest are intermittently denied access while the first forest's users are unaffected.
Which cause best fits?
a) The second EVS cannot reliably reach or authenticate against its own AD domain's name services
b) The cluster can only ever be joined to one Active Directory forest at a time
c) Object-based replication between the EVSs has desynchronized their user accounts
d) The first EVS is consuming all the QoS bandwidth, starving the second
04. An aggregated client link on an HNAS node delivers far less than the sum of its member ports, and traffic is piling onto only one or two members.
Which cause should the implementer investigate first?
a) A virtual-volume quota is throttling the busy member ports
b) HDRS is compressing the traffic and halving throughput
c) The aggregation has silently converted the link to Fibre Channel
d) The load-balancing hash is distributing flows unevenly across the member ports
05. Why is a read-only snapshot schedule not a complete substitute for backups in an HNAS deployment?
a) Snapshots consume pool space and depend on the same system, so they are a fast recovery aid rather than an independent backup
b) Snapshots cannot be taken while clients are connected
c) Snapshots can only be kept for a single day
d) Snapshots encrypt the file-system data at rest, which makes retaining them for long periods impossible without extra key-management overhead
06. On VSP One File, the data-reduction work that HDRS performs is handled differently from a general-purpose software NAS, which is central to its deployment story.
How is that data-reduction work carried out?
a) It runs entirely as a background software process on the client hosts
b) It relies solely on the general-purpose CPU with no hardware acceleration
c) It is hardware/FPGA-assisted to limit the impact on file-serving performance
d) It is performed on the back-end VSP block array before the file nodes see the data
07. When a thin file system on an HNAS storage pool needs space for new writes, how is that space allocated from the pool?
a) By reserving the file system's full configured size immediately
b) In whole chunks taken from the pool's stripesets on demand
c) By moving data off a lower tier regardless of pool type
d) By creating an additional stripeset for each new file
08. What is the primary purpose of a Performance Information Report (PIR) on an HNAS node or cluster?
a) To create a recoverable point-in-time copy of a file system
b) To apply a data-reduction policy to a file system
c) To capture node or cluster performance data for analysis and support escalation
d) To migrate cold data to an external cloud target
09. During file-system setup an implementer must decide whether a new file system should be allowed to consume pool space only as data is written, or to hold a fixed allocation.
Which file-system property governs that choice?
a) Its thin-provisioning setting, which determines whether it draws chunks on demand or holds a fixed allocation
b) Its quota type, which reserves pool capacity in advance
c) Its QoS policy, which decides how much pool space the file system may reserve and how quickly it is allowed to grow
d) Its replication mode, which sets how space is pre-allocated
10. Clients report that some files in a migrated HNAS file system return errors on read, while other files are fine, and the affected files are all XVL stubs.
What is the most likely cause?
a) The clients are using the wrong file protocol for those files
b) The external NFSv3 migration target those stubs point to has become unreachable
c) Deduplication has corrupted the affected files
d) The entire file system is offline
