NEW QUESTION # 76
A customer has a LUN that is already mapped and connected to a host using FCP. They now want to map the same LUN to another host using iSCSI.
Which two tasks would enable the administrator to share the LUN? (Choose two.)
Answer: A,B
Explanation:
ONTAP igroups can be created with an fcp, iscsi, or mixed protocol type. An iSCSI igroup is therefore valid for presenting the existing LUN specifically to the new iSCSI host. A mixed igroup is also valid because it permits both Fibre Channel and iSCSI initiators and can be used when access to a LUN involves both protocol types. ONTAP permits an igroup to be mapped to multiple LUNs and a LUN to be presented through appropriate SAN igroup mappings. Creating another FC-only igroup would not accommodate the new iSCSI initiator. A subsystem belongs to the NVMe architecture and is used to map NVMe namespaces to NVMe hosts; it is not used for FCP or iSCSI LUN presentation. Thus, both iSCSI and mixed igroups are valid configurations for the requirement.
NEW QUESTION # 77
A customer wants a NetApp ONTAP All SAN Array (ASA) cluster set up with a redundant Ethernet configuration.
What needs to be configured to achieve this?
Answer: A
Explanation:
IP SAN redundancy requires independent storage paths between each host and both nodes of the HA pair.
NetApp SAN networking guidance recommends creating multiple iSCSI paths from each node and specifically allows two data LIFs per node to provide connectivity through separate Ethernet networks. These networks should use separate IP subnets or ranges so that loss of one network, switch, port, or path does not eliminate host access to the storage. Host-side MPIO then uses the remaining paths during a failure. A node- management LIF provides administrative connectivity and is not a redundant data path. Selective LUN Mapping controls which cluster nodes report a LUN, while separate SVMs are not required merely to create network redundancy. Therefore, at least two data LIFs per node across separate IP networks provide the requested redundant Ethernet SAN configuration.
NEW QUESTION # 78
Which two steps must be taken first to restore a LUN from a SnapMirror Synchronous destination? (Choose two.)
Answer: B,C
NEW QUESTION # 79
Which NetApp ONTAP storage efficiency method provides storage savings by placing multiple different
1KB files in the same block?
Answer: B
Explanation:
Data compaction reduces physical storage consumption by combining multiple small data chunks into a single physical 4 KB block. ONTAP normally works with 4 KB blocks, meaning that a small object such as a 1 KB file could otherwise consume an entire 4 KB block. Inline data compaction combines such small pieces of data while they are still in memory, allowing several independently addressable data fragments to share one physical block. Compression differs because it reduces data size by encoding data into compression groups, while deduplication eliminates duplicate blocks. Thin provisioning controls capacity allocation rather than block packing. Therefore, when the requirement specifically refers to placing multiple different 1 KB files or data fragments into the same block, compaction is the applicable ONTAP storage-efficiency mechanism.
NEW QUESTION # 80
When data is written to a LUN in a four-node MetroCluster configuration, what feature is used to replicate data to the remote site?
Answer: B
Explanation:
MetroCluster uses SyncMirror technology to synchronously mirror data between storage pools at the two MetroCluster sites. Mirrored aggregates contain local and remote plexes, and writes are replicated synchronously so that a current copy of the data exists at the remote site. This storage-level mirroring is fundamental to MetroCluster ' s ability to maintain data availability during site failures and perform switchover operations. SnapMirror active sync is a separate ONTAP technology that provides synchronous application-level protection between peered clusters. SnapMirror Synchronous is likewise a replication technology but is not the underlying aggregate-mirroring mechanism used by MetroCluster. MPIO operates on the host to manage multiple SAN paths and performs no data replication. Therefore, data written to a LUN residing on a mirrored MetroCluster aggregate is replicated to the remote plex through SyncMirror.
