NEW QUESTION # 80
Which feature enables simultaneous snapshots of multiple LUNs In different volumes?
Answer: B
Explanation:
The feature that enables simultaneous snapshots of multiple LUNs in different volumes is Consistency Groups. This feature ensures that snapshots taken across different LUNs and volumes are consistent with each other, making it possible to recover a consistent state across multiple storage objects.
For further information, refer to:
* NetApp Documentation on Consistency Groups
NEW QUESTION # 81
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: B
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.
NEW QUESTION # 82
What are two possible options for iSCSI authentication methods? (Choose two.)
Answer: C,D
Explanation:
ONTAP defines the supported iSCSI authentication types as CHAP, deny, and none. Therefore, among the options provided, CHAP and deny are the two valid choices. CHAP authenticates an initiator by using a username and password. ONTAP supports inbound CHAP, where the storage system authenticates the initiator, and optional outbound CHAP for mutual authentication. The deny authentication type explicitly prevents the specified initiator from accessing the SVM. Certificates and SAML are not available values for ONTAP iSCSI initiator authentication. The vserver iscsi security create command exposes the authentication type as {CHAP|deny|none}. Consequently, the V9.02 supplied answer A, B is incorrect and has been corrected to A, C. Relevant topics include iSCSI security, CHAP, mutual CHAP, initiator credentials, and authentication policies.
NEW QUESTION # 83
A customer has a 10GB volume with an 8GB LUN that is using 7GB. The snapshot policy is hourly and retains 48 snapshots. After a ransomware attack that encrypts all files on the LUN, the customer notices that all snapshots are gone.
What could cause this behavior?
Answer: D
Explanation:
The likely cause for the disappearance of all snapshots after a ransomware attack that encrypted all files on the LUN is the Snapshot autodelete feature. When the volume becomes full due to the encryption, the autodelete feature removes older snapshots to free up space, preventing the volume from running out of space and ensuring write operations can continue.
For more information, see:
* NetApp Documentation on Snapshot Autodelete
* NetApp Community Discussion on Snapshot Deletion
NEW QUESTION # 84
A customer has data in a LUN on an existing third-party SAN storage system that will be migrated to a new NetApp AFF A400 all-flash MetroCluster system. The host connected to the LUN is a Windows Server 2019 system.
In this scenario, which two methods are supported? (Choose two.)
Answer: B,C
Explanation:
To migrate data from a LUN on an existing third-party SAN storage system to a new NetApp AFF A400 all- flash MetroCluster system, the supported methods include:
* Foreign LUN Import in online mode: This method allows for data migration without significant downtime, enabling the system to continue serving data while the migration process is ongoing.
* Foreign LUN Import in offline mode: This method involves taking the LUN offline during the migration process, which may be necessary in certain scenarios to ensure data integrity.
For more details, refer to:
* NetApp Documentation on Foreign LUN Import
* NetApp Community on LUN Import Methods
