Q2. - (Topic 1)

A user is reporting trouble using a SVM management LIF. You have verified host configuration, network connectivity, and that the LIF responds to pings.

What should you do to continue troubleshooting this problem?

A. Ensure the SVM management LIF’s failover policy is correct.

B. Ensure the SVM management LIF’s administrative status is up.

C. Ensure the SVM management LIF is on its home port.

D. Ensure the SVM management LIF’s firewall policy is set to management.

Answer: A

Explanation: Explanation: You must have prepared the.SVM.networking for a major upgrade by creating the necessary.SVM.management LIFs, failover groups, and routes. Reference:https://library.netapp.com/ecmdocs/ECMP1636041/html/GUID-5B0E96CF-78F8-40B9-A62D-C5A6E62A53D7.html

Q7. - (Topic 2)

Which statement is true about expanding an aggregate from 32-bit to 64-bit in place?

A. All aggregates are automatically converted from 32-bit to 64-bit with the Data ONTAP

8.1 upgrade.

B. The expansion is triggered by an aggr convert command.

C. The expansion is triggered by adding disks to exceed 16 TB.

D. The 32-bit aggregates are degraded and must be Volume SnapMirrored to a new 64-bit aggregates with Data ONTAP 8.1 upgrade.

Answer: C

Explanation:

The expansion process is triggered only when you add disks to a 32-bit aggregate such that the resulting aggregate capacity is greater than 16tb. When disks are added, if the resulting capacity is less than 16TB, the aggregate will continue to be 32-bit. Add enough storage to a 32-bit aggregate to increase the size beyond 16TB.

Q8. - (Topic 2)

Which NetApp Virtual Storage Tier component works at the host level?

A. Flash Pool

B. Flash IO

C. Flash Disk

D. Flash Accel

E. Flash Cache

Answer: D

Explanation:

With two recent product additions to VST, NetApp now offers end-to-end Flash options spanning from the client application through the disk subsystem. Controller level. Storage controller–based Flash—NetApp. Flash Cache—retains hot, random read data. (You can learn more about the algorithms used by Flash Cache and other details in a previous Tech OnTap. article.) Disk-subsystem level. NetApp Flash Pool technology uses a hybrid model with a combination of SSDs and HDDs in a NetApp aggregate. Hot random read data is cached and repetitive write data is automatically stored on SSDs. Server level. NetApp Flash Accel. technology extends VST into the server. It uses any server-side Flash device (PCI-e Flash card or SSD) as a local cache that off-loads I/O from networks and back-end storage to deliver optimum I/O efficiency to your busiest applications while freeing up server CPU and memory resources. All three levels continue to offer the full advantages of VST, including: Real-time promotion of hot data with high granularity. Hot data enters VST immediately, and its 4KB granularity means that it uses Flash-based media very efficiently. Easy to deploy and simple to manage. VST works with your existing data volumes and LUNs. It requires no complicated or disruptive changes to your storage environment. There is no need to set policies, thresholds, or time windows for data movement. Fully integrated. VST is fully integrated with the NetApp Unified Storage Architecture, which means that you can use it with any NAS or SAN storage protocol with no changes.
