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. The write pending limit of the partition will be raised until it reaches 80%
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.
What describes the difference between Asynchronous and Synchronous Copy on First Write (COFW)?
A. Asynchronous mode results in fewer disk operations during COFW.
B. Asynchronous results in a shorter host response time as there is no COFW penalty compared to Synchronous.
C. Asynchronous mode results in more disk operations during COFW.
D. Asynchronous and Synchronous mode result in similar host response time as both suffer the COFW penalty.
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.
A customer wants to migrate a database using Open Replicator. They have decided to do a hot pull operation to minimize the outage window. What should the customer do to prevent data corruption?
A. Mask the control devices to the host so both devices can be updated.
B. Unmount the remote device.
C. Wait to zone control devices until data is copied.
D. Mask the remote devices after data is copied
What is the EMC recommended network quality for SRDF/S over GigE?
A. Less than 0.1% packet loss
B. Less than 0.01% packet loss
C. Less than 0.25% packet loss
D. Less than 1% packet loss
A proposed SRDF/S solution was modeled with BCSD. The model assumed that the source array had 4 GigE ports. The RA Utilization chart shows the maximum utilization is at 70%.
How many GigE ports should be recommended to ensure a successful implementation?
A. 4
B. 5
C. 6
D. 8
You are designing an SRDF/A solution with Symmetrix VMAX 40K arrays. TimeFinder/Snap will be used to replicate the remote devices.
What is a design consideration?
A. Device Write Pacing should be enabled
B. Group Write Pacing should be enabled
C. Delta Set Extension should be implemented
D. Transmit Idle should be enabled
You need to model several SRDF/A workloads that require data consistency across all the sessions. How would you model the multiple SRDF/A sessions?
A. In BCSD, link them by creating a Composite Group
B. In SymmMerge, link them by creating a Composite Group
C. In BCSD, link them by creating a Logical Relationship
D. In SymmMerge, link them by creating a Logical Relationship
Refer to the exhibit.
You are considering potential configurations of a new storage system. You need to make decisions that consider different cost-benefit ratios. Which policy applied to the workload provides the best response time for the minimum expenditure?
A. Moderate Skew
B. Heavy Skew
C. Low Skew
D. Default Skew
