Demo Questions
Question 1
A customer needs to import and export volumes between IBM Spectrum Virtualize clusters that are geographically separated.
How can this be accomplished?
- Create image mode volumes
- Snapshots with Transparent Cloud Tiering
- Implement IBM Spectrum Archive
- Utilize tiering-to-tape media
Correct answer: B
Explanation:
Transparent cloud tiering is a licensed function that enables volume data to be copied and transferred to cloud storage. The system supports creating connections to cloud service providers to store copies of volume data in private or public cloud storage. With transparent cloud tiering, administrators can move older data to cloud storage to free up capacity on the system. Point-in-time snapshots of data can be created on the system and then copied and stored on the cloud storage.

Question 2
Which component of IBM Spectrum Scale enables data to be imported from several servers at the same time?
- HDFS Transparency connector
- IBM Spectrum Protect integration
- Cloud Object Storage support
- Multi-Cluster feature
Correct answer: B
Explanation:
With Spectrum Scale multiple Spectrum Protect instances use the same storage Capacity and performance management is seamless within a global name space Scalability is seamless and transparent File system replication is integrated with Spectrum Scale for different platforms Central administration of TSM storage
Note: Multiple Spectrum Protect (TSM) instances store DB and storage pools in a Spectrum Scale file system (GPFS)Spectrum Scale provides global name space for all Spectrum Protect instances Instances share all file system resources Spectrum Protect instances run on cluster nodes accessing the file system and disk directly Spectrum Scale file systems balances the workload and capacity for all TSM instances on disk Provides standardized, scalable and easy to use storage infrastructure for the multiple instances Incorrect Answers:A: IBM Spectrum Scale HDFS transparency offers a set of interfaces that allows applications to use HDFS Client to access IBM Spectrum Scale through HDFS RPC requests.References: https://www-03.ibm.com/support/techdocs/atsmastr.nsf/5cb5ed706d254a8186256c71006d2e0a/3264fd1e3716c13586257f460072493d/$FILE/SpectrumProtect_on_Spectrum%20Scale_Intro_v6.3.pdf With Spectrum Scale multiple Spectrum Protect instances use the same storage

Question 3
A customer asks about the implication of replacing a current tape library with a single disk-only IBM TS7760.
Which key point should the technical specialist address?
- Validate that the new virtual library emulates the correct drive type.
- Confirm the compression ratio on the tapes to calculate the disk space needed.
- Identify the current provision for tape vaulting and disaster recovery.
- Check whether current tape media is encrypted.
Correct answer: A
Explanation:
The TS7700 is a member of the TS line of products and builds upon previous implementations of tape storage virtualization. For example, the TS1155 Tape drive is not compatible with IBM TS7700 or Enterprise Tape Control Unit environments.

Question 4
A customer wants to replace an existing HDS system connected to an IBM z/OS mainframe with a storage solution to reduce cooling requirements and potential of mechanical failure.
Which storage solution should the technical specialist recommend?
- IBM FlashSystem 900
- IBM FlashSystem V9000
- IBM DS8886 HPFE
- IBM DS8884 with SAS drives
Correct answer: D
Explanation:
IBM invented the z Systems I/O architecture. Systems, SAN and DS8880 are jointly developed. IBM invented the z Systems I/O architecture. Systems, SAN and DS8880 are jointly developed.
Question 5
A customer has existing SAP HANA production nodes connected to an IBM Elastic Storage Server (ESS). The customer needs to scale out additional ESS nodes to maintain the high I/O throughput requirement.
Which type of nodes should be proposed?
- Storage nodes with SAS drives
- Storage nodes with SSD drives
- Protocol nodes with SAS drives
- Protocol nodes with SSD drives
Correct answer: B
Explanation:
A scale-out NAS system is comprised of multiple NAS storage nodes with internal or external storage. Each NAS storage node represents the same file systems to user applications. Data is stored across all NAS storage nodes, and adding capacity can be achieved by adding more storage nodes.
