NEW QUESTION # 18
Where is the zoning configuration stored in an FC SAN environment?
Answer: B
Explanation:
Fibre Channel zoning is configured and maintained within the FC switching fabric. ONTAP hosts and storage LIFs provide WWPN identities, but the switch configuration determines which initiator and target ports are permitted to communicate. NetApp's FC zoning guidance instructs administrators to log in to the FC switch administration interface, create zones containing host initiator WWPNs and ONTAP FC LIF WWPNs, save the zones, and activate the resulting zone configuration. Cisco environments use zones and zonesets, while comparable constructs exist on Broadcom/Brocade fabrics. Neither the host HBA nor the ONTAP storage system stores the authoritative fabric zoning configuration. Therefore, the FC switches are the correct location. Relevant SAN ONTAP topics include FC fabric design, WWPN zoning, zonesets, dual-fabric configurations, and SAN connectivity.
NEW QUESTION # 19
A customer is using a new two-node NetApp All SAN Array (ASA) configuration with SnapMirror active sync. To verify that everything is set up correctly, the customer is reviewing the number of paths on the ESXi hosts.
How many paths should the customer see?
Answer: D
Explanation:
Eight Active/Optimized paths and zero Active/Unoptimized paths is the correct result for the described ASA configuration. NetApp All SAN Array systems use symmetric active-active multipathing, under which all valid paths to a LUN are presented as active and optimized. NetApp's VMware guidance likewise states that ESXi recognizes ASA storage as symmetric and uses the active paths with round-robin multipathing. With SnapMirror active sync and the host connected through the intended redundant paths, the expected path presentation therefore does not contain the Active/Unoptimized paths characteristic of asymmetric access on non-ASA configurations. The key distinction is that ASA pathing is designed to avoid waiting for an ALUA transition after a controller failure. Relevant SAN ONTAP topics are ASA symmetric active-active, ALUA, ESXi multipathing, SnapMirror active sync, and redundant SAN paths.
NEW QUESTION # 20
A customer has recently installed a new NetApp AFF system and Cisco Nexus 9000 Series switches for their SAN workload. The administrator is tasked with configuring interface groups for port-based load balancing.
Which two commands are required? (Choose two.)
Answer: C,D
Explanation:
ONTAP interface groups support several traffic-distribution algorithms, including port, which distributes traffic using transport-layer TCP or UDP port information. Therefore, network port ifgrp create -distr-func port establishes the corresponding ONTAP-side distribution behavior. The connected Cisco Nexus infrastructure should use a compatible port-channel hashing method; NetApp validated architectures show port-channel load-balance src-dst l4port for Nexus switches so source and destination Layer-4 ports contribute to traffic distribution. This improves utilization across member links compared with algorithms using fewer flow attributes. The original V9.02 text contained the typographical string 14port; the correct command parameter is l4port, meaning Layer 4 port. Options C and D do not establish the requested port-based load- balancing algorithm. Relevant SAN ONTAP topics include interface groups, port distribution functions, link aggregation, and Nexus port-channel hashing.
NEW QUESTION # 21
To protect against an on-site disaster, which NetApp protection method should an administrator use to provide a Zero RTO for applications in a SAN environment?
Answer: A
Explanation:
SnapMirror active sync is the ONTAP data-protection technology designed to provide Zero Recovery Time Objective for business-critical SAN applications. It synchronously replicates protected application data between ONTAP clusters and uses host multipathing plus ONTAP Mediator-assisted automatic failover so that application access can continue when the primary storage system or site becomes unavailable. NetApp explicitly describes SnapMirror active sync as providing Zero RTO or Transparent Application Failover for SAN environments. SnapMirror asynchronous cannot provide Zero RTO because replication is not continuously synchronous and recovery requires a failover workflow. SnapMirror SVM and FlexClone LUNs also do not provide the same automatic, synchronous application failover behavior. Relevant SAN ONTAP topics are SnapMirror active sync, synchronous replication, consistency groups, ONTAP Mediator, automatic failover, and SAN business continuity.
NEW QUESTION # 22
An engineer Is implementing a data migration scenario for a customer who has multiple FC LUNs across multiple third-party SAN arrays. The engineer wants to use Foreign LUN Import (FLI) for the migration.
What is a requirement on the destination NetApp ONTAP cluster for FLI?
Answer: C
Explanation:
When using Foreign LUN Import (FLI) for migrating LUNs from third-party SAN arrays to a NetApp ONTAP system, one of the requirements is to have at least one Fibre Channel (FC) port configured in target mode on the destination NetApp ONTAP cluster. This configuration is necessary to facilitate the migration process as the target mode port will accept and manage incoming data from the source SAN arrays.
For additional details, refer to:
