What replication technology would you recommend?
During a design session with the customer, you determine that they require all tier one LUNs on the production VNX be replicated to a remote VNX. They also require the ability to be able to restore or mount the data at any given time during the day.

What does the splitter do after it intercepts a write I/O meant for a RecoverPoint Protected LUN?
A customer wants to use RecoverPoint/SE CRR. They have just realized that they need to use RecoverPoint write splitters, but do not understand how they work.

How many RecoverPoint clusters at each site must you plan for?
You are sizing a new RecoverPoint/SE CRR installation for a customer. You have gathered data from their environment and have decided that they will need 142 consistency groups.

If the total primary image workload consists of 1 KiB random I/Os with a R/W ratio of 3:1, what is the maximum
Click on the calculator icon in the upper left-hand corner. Your customer wants to use a VNX system at an unmanned DR site. The system will be used exclusively as a secondary MirrorView/A system, and it is capable of performing 60,000 LUN IOPs in this role. The primary system is also a VNX.
If the total primary image workload consists of 1 KiB random I/Os with a R/W ratio of 3:1, what is the maximum bandwidth required for the link between the VNX systems?
How is RPO calculated in MirrorView/A environments?

Under what conditions would you increase the TOS setting?
During data collection, the Time Out of Sync (TOS) setting is currently set at 10 minutes. You recommend a larger TOS setting based on the data that will be replicated.
Under what conditions would you increase the TOS setting?
What is a recommended configuration to have CIFS replicated?
A new customer is looking at purchasing two new VNXs and wants to replicate the CIFS environment.
What is a recommended configuration to have CIFS replicated?
What would you recommend to avoid interruption?
Your customer calls you about their new replication solution. CIFS access is being interrupted intermittently on the replication target.

What is the best practice for FAST Cache on MirrorView/A?
You are reviewing the array configuration of a VNX array that has MirrorView/A enabled. You notice that all the images related to MirrorView/A have FAST Cache disabled. What is the best practice for FAST Cache on MirrorView/A?
If the primary image workload consists of 4 KiB random IOs with a R/W ratio of 3:1, what is the maximum bandwi
Click on the calculator icon in the upper left-hand corner. Your customer wants to use a VNX system at an unmanned DR site. The system will be used exclusively as a secondary MirrorView/A system, and it is capable of performing 30,000 LUN IOPs in this role. The primary system is also a VNX.
