NEW QUESTION # 103
A storage administrator has just completed an ISCSI implementation in a customer environment running VMware and needs to validate that the entire network path supports jumbo frames.
Which action should be taken?
Answer: C
Explanation:
To validate that the entire network path supports jumbo frames after an iSCSI implementation, you should perform a ping test from the host with fragmentation. This involves using the ping command with specific options to test jumbo frame support:
ping -M do -s 8972 < target_IP >
In this command:
* -M do ensures the packets are not fragmented.
* -s 8972 sets the packet size to 8972 bytes (9000 bytes MTU minus 28 bytes for the ICMP header).
By confirming that the large packets are successfully transmitted without fragmentation, you can validate that the network path, including switches and adapters, supports jumbo frames.
For more details, you can check:
* NetApp Documentation - iSCSI Configuration and Best Practices ( NetApp ) ( NetApp ).
NEW QUESTION # 104
A customer is deploying an IP-based SAN on a NetApp AFF All SAN Array (ASA) system. A solution should be used that will increase security and improve reliability.
What is a network best practice for IP-based SAN when implementing AFF ASA infrastructure solutions?
Answer: D
Explanation:
Separate VLANs are a recommended design practice for IP-based SAN traffic because they provide logical network segmentation and enable independent broadcast domains. ONTAP VLANs can separate storage traffic by function or network path even when the underlying physical switching infrastructure is shared. For SAN redundancy, NetApp also recommends separate Ethernet networks and multiple paths so that failure of one network does not eliminate storage connectivity. VLAN separation additionally limits unnecessary broadcast-domain exposure and provides clearer operational boundaries for iSCSI or NVMe/TCP traffic. An MTU of 1500 is supported but does not inherently provide the requested security and reliability improvement, while simply using routed networking is not the relevant SAN best practice. Therefore, separate VLANs provide the appropriate segmentation and path-isolation characteristics for an AFF ASA IP SAN design.
NEW QUESTION # 105
A customer deploys an SVM for FCP with four LIFs across two fabrics. Equal client traffic is seen across all four LIFs.
In this scenario, how is the traffic across the active, unoptimized paths forwarded to the node hosting the LUN?
Answer: A
Explanation:
In a traditional AFF or FAS SAN configuration using ALUA, paths through the controller that owns the LUN are reported as Active/Optimized. Paths entering through another controller can be Active/Non-Optimized.
When I/O arrives through an active, non-optimized path, ONTAP must forward that I/O internally to the node servicing the LUN. This indirect data path uses the ONTAP cluster interconnect, represented in the choices as the cluster network, and therefore introduces additional latency compared with a direct optimized path. The external FC fabric transports traffic only as far as the target LIF; the HA interconnect is associated primarily with HA-pair storage failover functions, and the peering network is used for intercluster communications and replication. Relevant SAN ONTAP topics include ALUA, optimized versus non-optimized paths, cluster interconnect forwarding, SLM, and FCP multipathing.
NEW QUESTION # 106
A customer Is deploying a new 8-node NetApp ONTAP cluster for their SAN workloads using FCP, NVMe
/FC, and NVMe/TCP.
In this scenario, which statement is true?
Answer: A
Explanation:
In a NetApp ONTAP cluster using FCP, NVMe/FC, and NVMe/TCP, it is important to understand that NVMe
/FC and FCP require different FC ports. This separation is necessary because the protocols, while both running over Fibre Channel, have different configurations and operational characteristics.
For more information, refer to:
* NetApp Documentation on NVMe Configuration
* NetApp Best Practices for SAN
NEW QUESTION # 107
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: C
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.
