1 Question: 1 Company.com needs a remote replication Exchange Solution. Currently the company is supporting 800 users and are expected to grow to 1600 users by next year. Four Storage Groups will be used to manage the user mailboxes. RPO is 20 minutes and the sites are five miles apart connected by two T1 connections. Which solution would best fit its requirement? A. Create a MirrorView/A solution using Consistency Groups. Set the update interval to 10 minutes B. Create a MirrorView/S solution dividing their LUNs between SPA and SPB using Consistency Groups C. Create a MirrorView/S solution placing all LUNs for an Exchange Storage Group on either SPA or SPB D. Create an Incremental SAN Copy solution dividing their LUNs between SPA and SPB, starting copies at 20 minute intervals Question: 2 MMC routinely uses MirrorView replication between two data centers. The company currently uses the Write Intent Log feature on both arrays. Recently, when the primary data center suffered a major outage, production workload was transferred to the remote data center.

Increase the number of concurrent sessions, D Question: 59 The HV Metal Company wishes to protect application data by mirroring LUNs from Site A to Site B. During testing with a single mirror, response time was acceptable with the CLARiiON utilization very low. The production environment has five mirrors, and the customer is complaining about slow response. You use Navisphere Manager to determine how the company's data is laid out, and note the following: Site A RAID 1/0 RAID Groups Single Data LUN on each RAID Group High Water Mark 80% Low Water Mark 60% Page 18 of 23

19 Write Cache 3072 MB Site B RAID 5 RAID Groups Single Data LUN on each of the first 2 RAID Groups 3 data LUNs on the third RAID Group High Water Mark 80% Low Water Mark 60% Write Cache 2048 MB What would you recommend to the customer? A. Change the Low Water Mark at Site B to 40% B. Disable Write Cache on the CLARiiON at Site B C. Change the LUN Element Size on Site B to 128 kb D. Move a LUN from the third RAID Group to one of the other RAID Groups at Site B Question: 60 What is the benefit of binding parity RAID groups vertically? A. Increased Front End Bandwidth B. Increased performance per RAID group C. Increased performance per individual disk D. Increased data availability to over % Question: 61 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 Question: 62 A customer wants to implement an exchange environment but is restricted by cost. The customer has calculated its read write ratio to be 3:1. Which RAID solution would you recommend for the Exchange Database LUNs? A. RAID-1/0 B. RAID-1 C. RAID-3 D. RAID-5 Page 19 of 23

20 Question: 63 SES Analysis, Inc. has two CX500s separated by a distance of 8 km. The company uses MirrorView, SnapView and SAN Copy in its environment. The company also recently bought a MirrorView/A license and wishes to implement several asynchronous mirrors. The company can create three asynchronous mirrors, but it receives an error message when trying to create the fourth. You note that SES Analysis has 31 LUNs using SnapView Snapshots, and that the total number of Snapshots is 47. SES is also using Incremental SAN Copy on 16 other Source LUNs. Each Incremental SAN Copy Session has two destinations. Another 16 Source LUNs have two Clones each. Why is SES seeing the error messages? A. The number of Snapshots exceeds the maximum allowed on a CX500 B. The number of Mirror and Clone images exceeds the number allowed on a CX500 C. The number of Incremental SAN Copy images exceeds the maximum allowed on a CX500 D. The required number of LUNs in the Reserved LUN Pool exceeds the allowed maximum on a CX500 Question: 64 When connecting a SUN host to a CLARiiON, you can only see LUNs thru one HBA. Navisphere Agent, CLI, and PowerPath are all loaded. What is a possible problem? A. DMP is enabled B. DMP is disabled C. The st.conf file is set up incorrectly D. Navisphere Agent has incorrect IP for one SP Question: 65 You would like to view Navisphere Analyzer log files on a laptop with no network connectivity.

GMN is attempting to mount clone based replica on the mount server. The mount fails. RM/SE config checker was run. It did not report any problems with the mount server configuration. What is the reason? A. Production server may be a clustered node B. Either of the servers may have Terminal Services installed C. SQL patch is different on the mount and production servers D. At least one FC cable connecting Mount Server to Fabric may be damaged Page 20 of 23

Use java -jar navi.jar -User user -Password password -address analyzer - retrieve - Location c:\\temp D.Use java -jar archiveretrieve.jar -User user -Password password -Address File archive.nar Location c:\\temp -Overwrite 1 -Retry 2 Question: 68 WWE Furniture Removers has a CX700 at its headquarters site, and a CX500 at its DR site. The sites are separated by a distance of 700 km. You have determined that MirrorView/A is the solution that best matches the company's needs. You need to plan the zoning for the company's sites to balance host I/O and MirrorView/A I/O across the CLARiiON ports. Which configuration would you choose? A. For the CX700: Host access to ports 1, 2 and 3, and MirrorView/A on port 0 of each SP For the CX500: Host I/O on port 0 and MirrorView/A I/O on port 1 of each SP B.
