• Question 1:

  Which two storage efficiencies are enabled by default on NetApp AFF systems? (Choose two.)

  A. postprocess compaction

  B. Inline compression

  C. Inline deduplication

  D. postprocess zero block detection

  Correct Answer: BC

• Question 2:

  You are asked by your network engineering team to make sure that your NetApp cluster is configured to run LACP on Its network ports. Which network component satisfies this request?

  A. VLAN

• Question 3:

  You need to configure data-at-rest encryption for your NetApp ONTAP 9.8 cluster. Your company does not have Key Management Interoperability Protocol (KMIP) services available but must require a passphrase to be entered when a node Is rebooted.

  In this scenario, which two actions should be performed to satisfy these requirements? (Choose two.)

  A. Configure an external key management server.

  B. Enable onboard key management.

  C. Enable cluster-wide FlPS-compliant mode.

  D. Enable common criteria mode.

  Correct Answer: BD

  Explanation: Enabling onboard key management by default you are not required to enter a passphrase when the node is rebooted. To be asked the password , you need to enable the common criteria mode also. Reference: https://docs.netapp.com/ontap-9/topic/com.netapp.doc.pow- nve/Encryption%20of%20data%20at%20rest.pdf

• Question 4:

  You need to Increase the number of files that can be created In a volume. Which two methods enable you to achieve this goal? (Choose two.)

  A. Increase the number of files permitted on the volume.

  B. Set the space guarantee to 'volume".

  C. Set the fractional reserve to "0".

  D. Increase the size of the volume.

• Question 5:

  You are asked to create a data LIF to allow object storage access to a bucket that is hosted in ON TAP software. In this scenario, which service is required for the LIFs service data policy?

  A. management-HTTPS

  B. data-S3-server

  C. management-BGP

  D. cluster-core

  Correct Answer: B

  Explanation: In this scenario, the data LIFs must be configured with a service data policy that includes the S3 server protocol in order to allow object storage access.

• Question 6:

  Exhibit.

  

  You have a 2-node NetApp FAS2750 ONTAP cluster. You create a new 20-GB LUN In a new 100-GB volume and write 10 GB of data to the LUN. No storage efficiencies are enabled for the volume or aggregate. Referring to the exhibit, which two statements are true? (Choose two.)

  A. ONTAP reports that the volume Is using 10 GB of Its containing aggregate.

  B. ONTAP reports the volume as 20% full.

  C. ONTAP reports that the volume Is using 100 GB of its containing aggregate.

  D. ONTAP reports the volume as 10% full.

  Correct Answer: AD

• Question 7:

  Exhibit.

  

  You have received an alert from Active IQ Unified Manager that interface eOc has gone offline. Network engineering asks for the corresponding MAC address for the port that has a problem. Referring to the exhibit, which MAC address would you supply to the engineering team?

  A. 02:a0:98:fl:2e:be

  B. 00:a0:98:fl:2e:b2

  C. 00:a0:98:fl:2e:b3

  D. 02:a0:98:fl:21:88

  Correct Answer: B

• Question 8:

  You want to configure Active Directory domain controller access for NetApp ONTAP cluster administration. In this scenario, which two actions would accomplish this task? (Choose two.)

  A. Configure an authentication tunnel through an admin SVM.

  B. Use the vservar active-directory create command to create a computer account on the domain for a non-CIFS SVM.

  C. Use the vserver active-directory create command to create a computer account on the domain for a CIFS SVM.

  D. Configure an authentication tunnel through an existing CIFS SVM.

  Correct Answer: BD

  https://docs.netapp.com/ontap-9/index.jsp?topic=%2Fcom.netapp.doc.pow-adm-auth- rbac%2FGUID-BC7B1934-DDE6-4AFB-A319-6C85D1ADACB6.html

  Configuring an authentication tunnel

  If you have already configured a CIFS server for a data SVM, you can use the security login domain-tunnel create command to configure the SVM as a gateway, or tunnel, for AD access to the cluster.

  Creating an SVM computer account on the domain

  If you have not configured a CIFS server for a data SVM, you can use the vserver active- directory create command to create a computer account for the SVM on the domain.

• Question 9:

  Exhibit.

  

  Referring to the exhibit, what would cause a customer to have an Issue with SVM eplc_fcp when mapping a namespace to a host?

  A. FC has not been licensed on the cluster.

  B. NVMe Is not configured for the SVM.

  C. FC switch zoning has not been done correctly.

  D. NVMe is not licensed on the cluster.

  Correct Answer: B

• Question 10:

  Which two storage efficiency features are enabled by default on AFF systems? (Choose two.)

  A. LUN-level compression

  B. aggregate-level compression

  C. aggregate-level inline deduplication

  D. volume-level Inline deduplication

  Correct Answer: CD
