2 QUESTON: 119 What is the maximum size for a LUN that can be connected from a storage subsystem to an N series gateway? A. 300GB B. 500GB C. 1TB D. 2TB QUESTON: 120 A customer has several AIX servers that run a mission-critical application. There are 24 paths per server to an IBM 2105 Enterprise Storage Server. The SAN infrastructure utilizes redundant fabrics for high availability. The customer schedules a maintenance window to perform firmware updates on the switches in one fabric, which results in an extended service disruption for the servers. Which of the following is the most appropriate configuration change to prevent disruption in the future? A. Upgrade the code set for SDD. B. Update to the latest AIX OS maintenance level. C. Install the AIX MPIO-capable device driver. D. Remove a minimum of eight paths per server. QUESTON: 121 Which of the following is a reason that the N series system maximizes RAID performance? A. Because it works on any number of disks. B. Because data can also be restored extremely fast from tape. C. Because it is configured for each networking protocol individually. D. Because the NVRAM permits writes to be gathered up, optimized, and safely deferred. QUESTON: 122 A customer has an IBM TSM backup solution. The AIX server has two HBAs and 39

3 uses an IBM TS3500 LTO tape library and DS4800 Storage. The customer is experiencing backup failures due to link loss conditions with the tape drive. Which of the following should be done to prevent these backup failures? A. Upgrade the TSM server to support Server-Free backup. B. Separate the HBAs in the server to minimize optical crosstalk. C. Add HBAs to the server and add separate tape and disk zones. D. Add HBAs to the server and add separate tape and disk LUN masking. Answer: C QUESTON: 123 What command is used to display WWPNs of HBAs on an N series gateway? A. netdiag -v B. storage show adapter C. fcp status adapter D. ifconfig -a QUESTON: 124 What are two limitations of the fabric-attached MetroCluster configuration for distances greater than 500m running DataONTAP 7.2? A. Software-based disk ownership is not supported. B. Hardware-based disk ownership is not supported. C. ATA storage is not supported. D. FC storage is not supported. E. NDMP is not supported. Answer: A, C QUESTON: 125 If N series read performance on a particularly large file or LUN degrades over time, what command can be used to optimize its layout? A. file B. vscan C. resize D. reallocate 40

4 QUESTON: 126 A customer with two b-type switch fabrics wants to consolidate the fabrics into a single fabric. When preparing for the fabric merge, the customer requests a quick method for reviewing the current zoning using their existing management tools. Which of the following reports should be suggested to the customer? A. Configuration Analysis and Device Accessibility B. Configuration Analysis and Zoning Wizard C. Zoning Wizard and Effective Configuration D. Device Accessibility and Effective Configuration Answer: A QUESTON: 127 A customer has four Cisco 9509s in their SAN. One was recently replaced. How can the customer restore their large zoning configuration? A. Copy the configuration file from one of the 9509s to the new unit. B. Use Fabric Manager to migrate the configuration from the rest of the Fabric. C. Swap Supervisor cards with one of the intact 9509s and copy its configuration. D. Rely on zone configuration update during fabric merge process. QUESTON: 128 A customer has two sites, one production (site A) and one backup site (site B). They use a two node MS cluster, one node in site A and one node in site B. Also there is one DS8300 Storage Subsystem at each site interconnected by Metro Mirror. Both cluster nodes need to have access to the Quorum device hosted on the DS8300 at site A. Therefore, interlinks are set up between sites A and B, and zoning is set so that both cluster nodes see the storage in site A. Assuming the storage in site A becomes unavailable, which of the following steps is the first to get the cluster working again? A. Change zoning for the two cluster nodes to site B and reboot servers. B. Wait until storage in site A becomes available again and reboot servers. C. Make the volumes accessible on the DS8300 at site B, change zoning for the two cluster nodes to site B, and reboot servers. D. Move server in site A to site B, change zoning so the two cluster nodes can see 41

5 the storage in site B, and reboot both cluster nodes. Answer: C QUESTON: 129 Which TWO of the following products support both Fibre Channel and FICON? A. Cisco MDS 9020 Switch ( ) B. IBM SAN18B-R SAN Router (2005-B18) C. IBM SAN32M-2 Switch ( ) D. IBM SAN32B-2 Switch (2005-B32) E. IBM SAN16M-R SAN Router (2027-R16) Answer: C, D QUESTON: 130 A customer is looking for a usability aid for their iscsi & FCP environments. They would like to automate many functions that typically require manual processes, like creating LUNs and mapping those LUNs to volumes. In addition, they would like to expand LUN capacity on-the-fly with no impact to application or system performance. What is the product to meet these requirements? A. SecureAdmin B. SnapValidator C. SnapManager D. SnapDrive QUESTON: 131 Customer has requirements to implement standard active/active configurations using the N5500 system to provide redundancy for the path from each controller to every disk shelf in the configuration. Which of the following solutions meets the requirements for multipath storage? A. Both nodes use system assigned disk ownership, have at least one Fibre Channel port for each controller for each loop in the configuration, and cable all loops for multipath storage B. Both nodes use software-based disk ownership, have two Fibre Channel ports for each controller for each loop in the configuration, all loops are cabled for multipath storage. 42

6 C. Each node may use its default disk ownership as long as it has two Fibre Channel ports for each controller for each loop in the configuration, all loops are cabled for multipath storage. D. Both nodes must use the same type of disk ownership, make sure there are enough onboard Fibre Channel ports or HBAs to accommodate the extra cables required for multipath storage. QUESTON: 132 Which of the following IBM N series licensed functions integrates SnapLock and SnapVault technologies to create a solution specifically designed for addressing compliance requirements for unstructured data? A. FlexClone B. LockVault C. MultiStore D. SnapRestore QUESTON: 133 A customer has a SAN256B director (switch A) in production. They would like to add a SAN32B-2 switch (switch B) to Switch A to enlarge the Fabric. Switch B was used in another Fabric. Which of the following is the fastest way of connecting switch B to switch A? A. Connect switch B to switch A using an ISL. B. Set unique domain ID and IP address at switch B and connect switch B to switch A using an ISL. C. Pull the existing configuration from switch A, apply it to switch B, configure switch B to have a unique domain ID, connect switch B to switch A using an ISL. D. Erase the zoning configuration of switch B, configure switch B to have a unique domain ID, connect switch B to switch A using an ISL. QUESTON: 134 Which of the following IBM N series licensed functions enables a writable replica of data volumes and data sets? A. FlexCache 43

7 B. FlexClone C. SnapMirror D. SnapShot 44
