You are implementing an HP Continuous Access EVA solution in a customer's HP-UX IT-environment. Which HP product should you recommend for business continuity?
HP-UX Metrocluster Continuous Access EVA
Which actions must be performed before creating the first copy set? (Select two.)
Create Vdisk at the source site.
Create disk groups at the source and destination sites.
Which statement is accurate when describing managed sets failover in a Continuous Access environment?
It can failover resources of the same type in one action.
You are designing a Continuous Access EVA solution for a customer's environment containing an EVA3000 and a new EVA4000. Your customer wants to create snapshots of Vdisks which are members of a DR group. What is the maximum number of snapshots per DR group in this environment?
You are designing a high-availability Continuous Access EVA solution for a customer. Which components are required when designing the whole solution? (Select two.)
two intersite links
two fibre-channel-adapters per host
Which redundancy level must a container for a pre-allocated snapshot have when the source already has other snapshots?
the same as other snapshots
You identified a data replication group state as merging. What does this mean?
Writes are written in sequence to the destination Vdisk from the log.
Which statements are correct for a data replication group normal mode? (Select two.)
It is also referred to as failsafe-disabled mode.
It is the default mode for a data replication group.
You are on a customer's site to perform a planned downtime. Which Continuous Access EVA entities can perform a fail-over? (Select two.)
Data replication group
Which statement is correct about Continuous Access EVA bidirectional replication? (Select two.)
The storage system contains both source and destination Vdisks.
Destination site servers can perform tasks like backup and data mining.
Which statements are correct regarding copy sets for Continuous Access EVA? (Select three.)
Copy sets in a DR group fail over together.
Copy sets in a DR group preserve write order.
Copy sets in a DR group share the same log disk
Which tool is required when using local replication with an active Microsoft SQL Server 2000 database?
StorageWorks DButil (Database Utility)
For which Continuous Access entity does a log disk collect host writes?
Which disk-group is recommended by HP for a log disk when running a data replication group in synchronous or standard asynchronous mode?
near-online disk group if available
You are planning a Continuous Access EVA solution for a customer with high availability requirements. What is the HP recommended placement of management servers in this environment? (Select two.)
two at the source site
two at the destination site
What must be done to ensure that the write order of all I/Os is maintained in a Continuous Access EVA environment?
Dynamic load balancing must be turned off on the host.
What does Continuous Access failsafe mode do? (Select two.)
It provides the highest level of data integrity.
It sets source Vdisks unwriteable if remote site is unreachable.
What are possible results of issuing a resume command? (Select two.)
normalization of the copy set
merging of the log to the destination Vdisk
What is the Continuous Access EVA license based on?
amount of replicated storage capacity of source and destination arrays
For which purpose is it possible to export the Replication Solutions Manager (RSM) database?
to rebuild the database in case of corruption or failure
You are running a Continuous Access EVA environment. How many servers in a CA environment does HP recommend be running RSM?
You are installing a Continuous Access environment on a customer's site. How are Vdisks presented after creating them?
All Vdisks in the data replication group must be preferred to the same controller.
You are integrating an EVA Continuous Access and Business Copy environment on a customer's site. This customer uses HP Data Protector for backup. Which Data Protector module provides a seamless integration of Business Copy into the backup environment? (Select two.)
Zero Downtime Backup EVA
How do you make sure the copy set storage allocation is complete?
Check the destination Vdisk properties page.
Which start methods can you use to start the Replication Solution Manager (RSM) locally on an HP OpenView Storage Management Appliance (SMA)? (Select two.)
Where do you set the write mode for a copy set?
on the Data replication group
You a running a local replication in your Enterprise Virtual Array environment using Replication Solutions Manager. What happens when the management and RSM server is rebooted during a RSM initiated replication task? (Select two.)
Local replication events are stopped
Running replication tasks are queued and continued after the reboot
To which structure is a log disk assigned?
data replication group
You want to perform a Continuous Access full copy in a customers EVA environment. What should be done to protect the customer's data before performing this action?
Perform a snapclone of the destination Vdisks.
How many mirrorclones can be created per source?
You are integrating a WDM Continuous Access EVA solution at a customer site. What is needed to maintain line-speed in this solution?
buffer-to-buffer credits on the switch
Which statement is correct regarding write modes in Continuous Access EVA?
Synchronous mode means an I/O acknowledgement is sent to the host after data is written to the source EVA cache and destination EVA cache.
Which action is called normalizing in a Continuous Access EVA environment?
The initial copy from the source Vdisk to the destination Vdisk is in progress.
Which statement is correct for a suspended DR group? (Select two.)
All members are suspended at the same time.
All source host I/O are written into the write history log.
Which statements are correct for merging and can impact performance? (Select two.)
Host I/O's go to the log first.
Merge I/O's have priority over host I/O's.
