NEW QUESTION # 33
An administrator connects to a LUN from Node A to a host in a redundant pathing configuration.
How does the administrator show that the LUN delivers data if a node disruption occurs?
Answer: D
Explanation:
A controlled storage takeover and giveback is the appropriate method for validating HA behavior without deliberately creating uncontrolled infrastructure failures. NetApp recommends testing an HA pair after configuration to verify uninterrupted access to storage during takeover and giveback. During takeover, the surviving HA partner assumes responsibility for the affected node ' s storage and continues serving its data.
Host multipathing redirects SAN I/O through surviving paths. Giveback subsequently returns storage ownership and processing to the home node. Pulling cluster-interconnect cables, removing rack power, or disabling backend connectivity introduces unnecessary failure conditions and can affect more infrastructure than required for a controlled validation. Therefore, performing takeover and giveback on the nodes verifies both storage-controller failover and the host ' s redundant SAN path configuration.
NEW QUESTION # 34
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: A
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 # 35
A storage engineer zones a new FCP SVM to an SQL cluster.
Which two commands can be used to check connectivity? (Choose two.)
Answer: A,C
Explanation:
ONTAP provides dedicated FCP connectivity tests for validating communication between host initiators and FC LIFs. The vserver fcp ping-igroup show command performs a connectivity check between FCP initiators contained in an igroup and the FCP LIFs through which those initiators are configured to connect. The vserver fcp ping-initiator show command performs the equivalent validation for an individual FC initiator. These commands are therefore appropriate after zoning a new FCP SVM to SQL hosts. cluster ping-cluster validates ONTAP ' s internal cluster network and is unrelated to host-to-storage FC connectivity. network fcp zone show displays discovered FC zoning information but is not the specific FCP initiator connectivity test requested. Relevant SAN ONTAP topics include FC zoning validation, igroups, WWPN connectivity, FCP LIFs, and SAN troubleshooting commands.
NEW QUESTION # 36
An administrator is configuring ISCSI on an SVM and requires that all network traffic Is encrypted. What must be done to satisfy this requirement?
Answer: B
Explanation:
To ensure that all network traffic is encrypted for iSCSI on an SVM, configuring IPsec is required. IPsec (Internet Protocol Security) provides end-to-end encryption for IP traffic, ensuring that data transmitted over the network is secure.
For more details, refer to:
* NetApp Documentation on Configuring IPsec
NEW QUESTION # 37
A storage administrator recently implemented ISCSI SAN in a customer environment. Which two actions should be done to ensure the best performance? (Choose two.)
Answer: B,C
Explanation:
To ensure the best performance in an iSCSI SAN implementation:
* Connect host and storage ports to the same switches: This minimizes latency and maximizes the efficiency of data paths by ensuring direct connections within the same network segment.
* Configure Jumbo frames in the entire data path: Setting a larger Maximum Transmission Unit (MTU) size reduces the overhead for processing each packet, thus improving overall network performance.
Ensuring Jumbo frames are configured end-to-end in the data path is crucial for optimal performance.

* NetApp Community Discussion on iSCSI Performance
