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?
A. Duplex mismatch
B. LACP speed mismatch
C. Incorrect subnet mask
D. Misconfigured authentication
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?
A. Once the original site is synchronized, the replication will return to the original state.
B. The additional sites must be manually re-synchronized through the CLI or GUI.
C. The original source site will cascade the file system updates to the remaining sites.
D. The DR site now becomes the source for all sites including the original source.
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?
A. 7,500 MB
B. 3,750 MB
C. 937.5 MB
D. 15,000 MB
A client is planning a virtualized SQL environment with remote protection. They want SQL- aware recoverable replicas. Which solution would you recommend?
A. Raw device mapping and VMHA
B. VMFS vDisk and MirrorView
C. VMFS vDisk and VMHA
D. Raw device mapping and MirrorView
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?
A. FAST Cache and ASM
B. FAST Cache and FAST VP
C. ASM and Thin Provisioning
D. FAST VP and Thick LUNs
A customer wants to migrate a LUN from one EMC VNX to another. The customer wants to use the integrated LUN migration feature. Due to a change freeze, the customer can install additional software, but cannot add any additional hardware. What do you recommend?
A. Use SAN Copy, rather than LUN migration
B. Configure target LUNs 20% larger than source LUNS
C. Configure Thin source LUNs and Thick target LUNs
D. Use RecoverPoint, rather than LUN migration
A storage administrator is finishing up some cabling in the production data center and notices that there is a flashing yellow LED light for a port on a Cisco IPS module. What does this indicate?
A. There is a fault.
B. The link is down.
C. The link is disabled.
D. Beaconing is enabled for the port.
A customer plans a CIFS DR solution for a Windows-only environment connected to an EMC VNX for File. The customer has the VNX antivirus solution implemented on the source site. The customer asks you if there are additional considerations regarding antivirus they need to account for in their CIFS DR solution. What do you advise the customer?
A. A global CIFS server will need to be configured on the VDMs CIFS server that is replicated to the destination site to provide antivirus protection during failover.
B. A global CIFS server will need to be configured on a physical Data Mover on the destination site to provide antivirus protection during failover.
C. The CIFS DR solution is not compatible with the VNX antivirus feature at either the source or destination site.
D. The destination site is protected by the source site VNX antivirus feature during failover events.
A customer has a Windows-only environment connected to a Celerra gateway utilizing Symmetrix storage at their main campus site. The customer plans to install a new EMC VNX at their remote site and implement a DR solution for their Celerra. The customer requires several thin-provisioned file systems be shared and available to clients via CIFS and wants to implement VDMs. Which solution do you recommend to the customer?
A. Use VNX Replicator to replicate the Celerra VDMs and associated file systems from the main campus site to the VNX at the remote site to provide an asynchronous DR solution.
B. Use VNX Replicator to replicate the Celerra VDMs and associated file systems from the main campus site to the VNX at the remote site to provide a synchronous DR solution.
C. Use VNX SAN Copy to replicate the Symmetrix devices associated with the Celerra file systems from the main campus site to the VNX at the remote site to provide a synchronous DR solution.
D. Use SRDF/A to replicate the Symmetrix devices associated with the Celerra file systems from the main campus site to the VNX at the remote site to provide an asynchronous DR solution.
You are setting up Perfmon to record the number of I/O per second for a customer's clustered SQL Server prior to a migration to an EMC VNX. Which Perfmon counter should you add to the log view to obtain this information?
A. Logical Disk\Disk Reads/sec and Logical Disk\Disk Writes/sec of the database and log LUNs
B. Physical Disk\Disk Reads/sec and Physical Disk\Disk Writes/sec of the database and log LUNs
C. Logical Disk\Disk Reads/sec and Logical Disk\Disk Writes/sec of the database LUNs
D. Physical Disk\Disk Reads/sec and Physical Disk\Disk Writes/sec of the database LUNs
