Which solution would you recommend?
A client is planning a virtualized SQL environment with remote protection. They want SQL-aware
recoverable replicas. Which solution would you recommend?
Which Oracle and VNX features would combine to handle hot-spots?
A staffing company runs their employee payroll on an Oracle 11g environment on an EMC VNX.
While the weekly payroll is running against Oracle, they also run reports. Which Oracle and VNX
features would combine to handle hot-spots?
How much data will be copied to the destination LUN?
A customer wants to reduce the performance impact incremental SAN Copy (ISC) has on their
source LUN. They plan to use a clone between the current source and destination LUN, and then
use the fractured clone as the new ISC source LUN. The source LUN performs four hundred 8 KB
random I/O per second, with a 3:1 read/write ratio.
The source LUN is 512 GB in size, and the clone will be fractured for five minutes.
How much data will be copied to the destination LUN?
How will replication occur to the remaining sites?
A customer has DR solution with EMC VNX configured to use a One-to-Many replication topology
for its file system environment. Their environment consists of the following:
• One system in the main office (Source)
• One system at a local DR site
• One system in the East coast office
• One system in the West coast office
• One system in the Canadian office
Over the weekend they experienced a failure on the source system at the main office and failed
over to the local DR site. On Monday, the source system was repaired and replication was
restarted and reversed from local DR site to the main office. How will replication occur to the
remaining sites?
What is the most likely cause of this performance issue?
A customer configured an EMC VNX to serve home directories to users. Users report intermittent
timeouts accessing the home directories. While troubleshooting, you observe you can
successfully connect to the file share, and can ping the VNX interfaces. What is the most likely
cause of this performance issue?
Which configuration provides maximum usable capacity balanced with reasonable performance?
A customer asks you to design an EMC VNX for an Oracle database composed of 300 GB RAID 1
and 600 GB RAID 5 (4+1) drives. Which configuration provides maximum usable capacity
balanced with reasonable performance?
What caused this situation?
A healthcare company uses MirrorView replication between VNX located at their two data centers.
They use the Write Intent Log (WIL) feature on both VNX. There was an outage at the production
data center and production workload was transferred to the DR data center. When then
production workload was failed back to the production data center, the customer found all
MirrorView LUNs completed a full re-synchronization. What caused this situation?
What action should they take to resume this VM’s operation?
A vSphere ESXi v5.0 administrator receives an alert that a VM (virtual machine) has been paused.
What action should they take to resume this VM’s operation?
What is the minimum number of 300 GB 15K SAS drives needed to meet the client’s performance and storage
Click on the calculator icon in the upper left-hand corner.
A client has a storage requirement for an object database. The application is expected to
generate random I/O requests. The I/O profile is:
– 70% random reads
– 30% random writes
– Total host I/O per second is 20,000
– Required usable capacity is 35 TB
The client is concerned about cost, so RAID 5 (8+1) data protection will be used.
What is the minimum number of 300 GB 15K SAS drives needed to meet the client’s performance
and storage requirements, including hot spares drives?
Which recommendation is most likely to improve performance for the home directory clients?
An EMC VNX supports several iSCSI Windows hosts, as well as a home directory structure for
fifty CIFS clients. The iSCSI hosts run an application with an I/O pattern that is 80% writes with a
2 MB I/O size. The customer reports overall write performance is less than expected. Your
examination of the VNX reveals frequent forced flushing. Which recommendation is most likely to
improve performance for the home directory clients?
