The questions of E20-845 exam:

1. A customer wants to split a BCV copy of the production database once a week and then use Clones of the BCV for testing.
Which operations are required to make a Clone usable by a host?
A.Activate the Clone and split the Clone
B.Establish the Clone and split the Clone
C.Split the BCV, create the Clone, and activate the Clone
D.Establish the BCV, create the Clone, and mount the Clone
Answer: C
2. A customer is using a RAID-1 standard device that already has a paired BCV and one CopyOnAccess Clone copy.
What is the maximum number of additional CopyOnWrite Snap sessions that the customer can create on this device?
A.1
B.7
C.13
D.16
Answer: C
3. After doing a BCV split and mount on a Window’s backup host, the customer determines the data on the BCV copy is inconsistent and missing files. The customer’s script is using the SUI utility symntctl.
Which command should be used to help prevent the inconsistent BCV?
A.umask
B.flush
C.umount
D.deport
Answer: B
4. A customer wants to implement a remote site replication via SRDF.
Which tool is used to calculate the number of tracks to be replicated?
A.EMC DRU
B.EMC TimeFinder
C.EMC Change Tracker
D.EMC Symmetrix Optimizer
Answer: C
5. You are validating a remote replica configuration where a RAID-1 protected R1 device needs to be replicated remotely to a RAID-1 protected R2 device. The source R1 device already is a part of a TimeFinder concurrent BCV configuration.
What should you consider to validate the configuration?
A.The number of I/Os between R1 and BCVs
B.Whether the R2 device is being remotely replicated to a RBCV
C.The number of mirror positions available to the RDF target device
D.The number of mirror positions available to the RDF source device
Answer: D
6. A customer needs to implement a multi-hop SRDF/AR configuration.
How does the bandwidth between Symmetrix arrays impact the potential amount of data lost in case of failure?
A.Less bandwidth means more cache required
B.Less bandwidth means longer SRDF/AR cycles
C.More bandwidth means longer SRDF/AR cycles
D.More bandwidth means potential data inconsistency in case of failure
Answer: B
7. A customer is implementing SRDF/A over GigE but is having problems getting through the corporate firewall.
What are the first steps for troubleshooting?
A.Verify cache on both DMXs exactly match, and COVDs are defined on both DMXs
B.Verify the SRDF link TCP/IP port matches on each DMX, and that port is open on the firewall(s)
C.Verify the Fibre adapters are configured as SNOW resources, and COVDs are properly defined in the bin files
D.Turn off data compression on the GigE adapters, verify TCP/IP addresses on both DMXs, and verify SNOW is defined on the SRDF GigE adapters’ bin file.
Answer: B
8. A customer has had security issues in the past. To resolve them, firewalls were set up between network segments within and external to his data center environment. You are configuring the communication between the Replication Manager server and the administration console(s).
Which port must be allowed to pass through the firewalls to facilitate administration?
A.6753
B.8080
C.65431
D.65432
Answer: D
