NEW QUESTION # 45
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: D
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 # 46
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: C
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 # 47
A customer has a new eight-node NetApp AFF cluster that will serve NVMe/TCP namespaces to clients.
Bidirectional in-band authentication is required between all NVMe hosts and the AFF cluster.
Which NetApp ONTAP feature must be configured to meet the requirement?
Answer: C
Explanation:
DH-HMAC-CHAP is the ONTAP mechanism for secure in-band NVMe authentication. NetApp documents that ONTAP supports both unidirectional and bidirectional authentication for NVMe/TCP and NVMe/FC by using DH-HMAC-CHAP. For bidirectional mode, a host secret and a controller secret are configured so that the controller authenticates the NVMe host and the host also authenticates the controller. The authentication configuration is associated with the NVMe subsystem host by its NQN. SAML, Kerberos, and an Active Directory domain tunnel are not NVMe transport authentication mechanisms and therefore do not satisfy this requirement. In current ONTAP releases, DH-HMAC-CHAP can be configured through System Manager or the CLI, depending on release. Relevant SAN ONTAP topics are NVMe subsystem host configuration, secure in-band authentication, host/controller secrets, and NVMe/TCP security.
NEW QUESTION # 48
Which two NetApp features enable an administrator to limit the number of paths that a host sees to a LUN?
(Choose two.)
Answer: A,D
Explanation:
Selective LUN Mapping (SLM) and portsets are ONTAP mechanisms specifically used to control the number of paths visible between hosts and mapped LUNs. SLM automatically limits LUN access to paths through the node that owns the LUN and its HA partner, reducing unnecessary paths in larger clusters. A portset provides additional restriction by defining exactly which FCP or iSCSI LIFs an igroup can use to reach its mapped LUNs. NetApp notes that portsets can be combined with SLM when further path restriction is required.
ALUA identifies optimized and non-optimized paths but does not itself reduce the number of visible paths.
An igroup controls which initiators can access a LUN but does not independently restrict target LIF visibility.
Relevant topics include SLM, portsets, igroups, SAN multipathing, and path-count optimization.
NEW QUESTION # 49
An engineer is troubleshooting FC connectivity issues on a customer's system and sees the following output from the network fcp adapter show command:
According to the output, what is the domain ID of the switch that is connected to port 2a of node n2?
Answer: D
Explanation:
The port address shown for node n2, adapter 2a is 10020. ONTAP reports the FC host port address as a hexadecimal fabric address. Fibre Channel port addresses are interpreted as a 24-bit FC address; when the displayed value is zero-padded to six hexadecimal digits, 10020 becomes 010020. The high-order byte is therefore 01, identifying switch domain ID 1. NetApp's network fcp adapter show command reference confirms that the command reports the Host Port Address and also exposes a domain-id field for the connected fabric. The other choices do not match the domain portion of this FC address. Therefore, the V9.02 supplied answer of D is incorrect for the displayed output. Relevant SAN ONTAP topics are FCP adapter diagnostics, FC port addresses, domain IDs, and fabric connectivity.
