Q2. An administrator wants to add an advanced statistic to a work sheet. How will the administrator make the statistic available?
A. No action is required. Advanced Statistics are enabled by default.
B. Under Configuration > Dashboard > Preferences, select "Make available advanced analytics statistics" and click Apply.
C. Under Status > Dashboard > Preferences, select "Make available advanced analytics statistics" and click Apply.
D. Under Configuration > Preferences, select "Make available advanced analytics statistics" and click Apply.
Answer: A
Explanation: By default, the Statistics available under Analystics are basic and useful to most storage administrators. http://www.bergendorf.net/files/7xxx-LAB_v07_p03.pdf

Answer: B
Q5. What type of cabling scheme is used when cabling two or more disk shelves?
A. Top Down/Bottom Up cabling scheme where the top and bottom disk shelves connect to the storage server
B. Cable disk shelves which directly connect to the storage server until you run out of SAS ports
C. Top Down/Bottom Up cabling scheme where the middle disk shelves connect to the storage server
D. Top Down/Bottom Up cabling scheme where only the top disk shelves connect to the storage server

Answer: C
Q6. Which three statements are true about Cluster Configuration of ZFS Storage Appliances?
A. In Cluster environment, only one node at a time can be the owner of each storage pool.
B. To utilize resource of both nodes simultaneously, you need at least two storage pools: one that maps to node1 and another that maps to node2.
C. Read SSD is in head node, so cached data will not fail over to another node. Warm-up time is required after failover in order to cache the data again.
D. In Cluster environment, only one controller can be assigned resources.
Answer: A,B,D

D. Only for 12 months
E. Indefinitely
Answer: C
Q9. Which option is true when allocating and verifying storage?
A. For expandable systems, JBODs can be allocated as "quarter/1 "half/1 or "whole."
B. In general, half JBODs are the preferred unit for managing storage, but quarter JBODs can be used where storage needs are small.
C. The allocation of hot spares depends on the storage profile chosen (for example, striped).
D. All devices must be connected and functioning before continuing past the verification step.
Answer: B
Explanation:
Verification and Allocation The verificationphase allows you to verify that all storage is attached and functioning, and allocatesdisks within chassis. In a standalone system, this presents a list of all available storage and drive types, with the ability to change the number of disks to allocate to the new pool. By default, the maximum number of disks are allocated, but this number can be reduced in anticipation of creating multiple pools. In an expandable system, JBODs are displayed in a list along with the head node, and allocation can be controlled within each JBOD. For each JBOD, the system must import available disks, aprocess that can take a significant amount of time depending the number and configuration of JBODs. Disks within the system chassis can be allocated individually (as with cache devices), but JBODs must be allocated as either 'whole' or 'half'. In general, whole JBODs are the preferred unit for managing storage, but half JBODs can be used where storage needs are small, or where NSPF is needed in a smaller configuration.
