Q3. - (Topic 1) 

A customer wants to use FlashCache but does not want to lose the information stored in the FlashCache card when a takeover occurs in a high-availability solution. 

What should the customer do to make sure this feature is enabled? 

A. Confirm that the aggregates using the FlashCache card are configured appropriately. 

B. Set the option to rewarm the FlashCache in both nodes of the HA pair. 

C. Verify that the FlashCache card is located in the appropriate slot in the NetApp controller. 

D. Verify that the FlashCache card has been configured only on the node where the feature is required. 

Answer:

Explanation: The system does not serve data from a Flash Cache or Flash Cache 2 module when a node is shutdown. However, the WAFL external cache preserves the cache during a graceful shutdown and can serve "warm" data after giveback. The WAFL external cache can preserve the cache in Flash Cache modules during a graceful shutdown. It preserves the cache through a process called "cache rewarming," which helps to maintain system performance after a graceful shutdown. For example, you might shut down a system to add hardware or upgrade software. Cache rewarming is enabled by default if you have a Flash Cache or Flash Cache 2 module installed. Cache rewarming is available when both nodes in an HA pair are running Data ONTAP 8.1 or later.

Q9. - (Topic 3) 

A storage administrator create a Quality of Service ( QoS) policy named pgMB300 which 

sets a maximum throughput of 300MB/s, and a second Quality of Service policy named pglO200 which sets the maximum throughput to 200 IOPS. The storage administrator assigns the pgMB300 QoS policy to Vserver vs1. The storage administrator then attempts to assign the pglO200 QOS policy to vol1 of vs1. 

What is the outcome? 

A. The attempt will succeed. You can assign Qos policy to storage object so long as single object does not have multiple policy groups assigned to it. 

B. The attempt will fail. You cannot have policies with differently maximum throughput units. They all have to be MB/s or all have to be IOPS. 

C. The attempt will succeed. You can nest IOPS policy limit instead a MB/s policy limit. 

D. The attempt will fail. You cannot nest policy groups in any manner. 

Answer:

Explanation: Explanation/Reference: 

In the following illustration, the Vserver vs3 is assigned to policy group pg2. You cannot 

assign volumes vol4 or vol5 to a policy group because an object in the storage hierarchy 

(Vserver vs3) is assigned to a policy group.
