• Question 22:

  A Symmetrix VMAX hosts four applications. Each application is assigned a named Dynamic Cache Partition. Two of the partitions are static and two are flexible. The write pending limit for each partition is set to 60%. What will happen if an application running in a flexible partition reaches the write pending limit set for that partition?

  A. Host write activity to that partition will be throttled
  B. Cache will be borrowed from the other flexible partition
  C. Cache will be borrowed from the default partition
  D. Write pending limit of the partition will be raised to 80%
  A. Host write activity to that partition will be throttled

• Question 23:

  You are designing a Symmetrix VMAX SRDF/S over Fibre Channel solution. The production and remote data centers are 50 km apart. What is the expected write response time delay due to latency?

  A. 0.25 ms
  B. 0.5 ms
  C. 1 ms
  D. 2 ms
  B. 0.5 ms

• Question 24:

  A customer has a pair of VMAX arrays configured to replicate thin devices at one site to thin devices at another site using SRDF/A. The customer wants to implement TimeFinder/Clone replication of the R2 device on the target array and asks you to confirm this is a supported configuration. What do you advise the customer?

  A. Yes, it is supported.
  B. It is supported only if composite groups are used.
  C. It is supported only if the precopy option is used.
  D. No, it is not supported.
  C. It is supported only if the precopy option is used.

• Question 25:

  A customer is interested in utilizing SRDF/AR to generate a remote copy of an application with an RPO of six hours. In order for you to calculate the bandwidth requirements you will need to run Change Tracker. To which should you set the reset interval length for DeltaMark?

  A. 21600
  B. 86400
  C. 32400
  D. 10800
  D. 10800

  A. Adaptive Copy Write Pending Mode
  B. Adaptive Copy Disk Mode
  C. SRDF/Synchronous
  D. SRDF Data Mobility
  A. Adaptive Copy Write Pending Mode

• Question 27:

  Where is the pace set when using Open Replicator?

  A. At the session level.
  B. On the Host HBA.
  C. On the Switch Port.
  D. At the Symmetrix FA port.

• Question 28:

  How many SDDF sessions can each Logical Volume support?

  A. 16
  B. 8
  C. 32
  D. 64
  C. 32

• Question 29:

  What is the effect of block size on response times in an SRDF/S environment?

  A. Larger block size applications experience higher response times
  B. Smaller block size applications experience higher response times
  C. Larger block size applications have the same response times as smaller block size applications
  D. Block size has no effect on response times
  A. Larger block size applications experience higher response times

• Question 30:

  When terminating a TimeFinder/Snap session, what is the effect on the ability to access the data on the VDEV?

  A. A host mount is required to access the data on the virtual device.
  B. The hold on the target device is removed while the data remains available.
  C. The data is available to the host if a mount is issued with the force flag.
  D. The data is no longer available on the virtual device.
  D. The data is no longer available on the virtual device.
