GWC uses a Windows 2000 server and a CX-series array to run its data warehouse application. For application development and testing, GWC is making use of the clone functionality in SnapView and scripted the fracturing and resynchronization. The scripts are run on the host under User Administrator. In the scripts the username and password for the
Navisphere user are specified. Due to security constraints, user name and password must be taken out of the scripts. Which two [2] actions must be performed after user name and passwords are removed from the scripts?
- A. Create the user Administrator in Navisphere Manager
- B. Run the NaviCLI ddUserSecurity command and specify the Navisphere user password.
- C. Run the java ar NaviCLI.jar ddUserSecurity command and specify the host user password
- D. Run the java ar NaviCLI.jar ddUserSecurity command and specify the Navisphere user password

Answer :
You use Navisphere Analyzer to determine the current performance of the 4+1 RAID 5 application LUNs used by the RRM Company. The customer uses a CX700. Each LUN is on a dedicated RAID Group consisting of 10 krpm 73 GB disks. Your analysis indicates that the response time for the LUNs varies between 10 ms and 35 ms during the day. You also find that the company is running between 350 and 500 IOPs each. The write/read ratio is around 33/67. Average seek distance on their 200 GB LUNs is 15 GB. RRM wants to add
SnapView to the environment. RRM's goal is to use Snapshots taken every two hours to restore the data in case of corruption. The customer asks for your recommendation. One of the factors you consider is the performance impact of using Snapshots. What do you estimate the impact to be?
- A. An additional read load of 100 IOPS on each Source LUN caused by the COFW process
- B. An additional write load of 100 IOPS on each Source LUN caused by the COFW process
- C. An additional read load of 1000 IOPS on each Source LUN caused by the COFW process
- D. An additional write load of 1000 IOPS on each Source LUN caused by the COFW process
Answer : A
Your customer, NCM, is concerned about the performance effects of SnapView on its
Source LUNs. Which actions do you take to determine the extra load?
- A. Load Analyzer. View the number of writes to the Reserved LUNs. This equals the extra write load on the Source LUNs
- B. Load Analyzer. View the number of reads from the Reserved LUNs. This equals the extra read load on the Source LUNs
- C. View the Session Properties in Navisphere Manager. Check the Number of Writes from the Reserved LUN Pool. This equals the extra read load on the Source LUNs
- D. View the Session Properties in Navisphere Manager. Check the Number of Writes from the Reserved LUN Pool. This equals the extra write load on the Source LUNs
Answer : C
Which option will have the lower latency on the backend when writing an entire stripe of data?

- B. 8+1 RAID-5 Group 73GB drives
- C. 4+4 RAID-1/0 Group 73GB drives
- D. 8+8 RAID-1/0 Group 73GB drives
Answer : A
