IBM i to achieve this.

What is the minimum number of cores that need to be licensed for PowerHA on the primary server?

A. 20 cores

B. 16 cores

C. 14 cores

D. 32 cores

An installation engineer has configured a new POWER9 processor-based server with two VIOS partitions. The client is questioning the use of resources for two VIOS partitions instead of one.

What benefit does the dual VIOS configuration provide?

A. Provides for better system performance and balance between client partitions.

B. Allows for upgrading the OS on partitions without application downtime.

C. Provides better Reliability, Availability and Serviceability (RAS).

D. Allows for dedicated I/O adapters.

Which of the following adapters is used to attach a FlashSystem 900 to a Power System E980?

A. An EDR InfiniBand adapter.

B. An optical CXP converter adapter.

C. A 16Gb Fibre Channel adapter.

D. A 12GB write cache SAS adapter.

What is the minimum amount of rack space that an 80 core Power System E980, without any I/O drawers, will take up in a 19 inch rack?

A. 10U

B. 12U

C. 16U

D. 8U

A customer's Disaster Recovery plan requires daily backup tapes from their POWER9 processor-based server to be sent off-site. The POWER9 processor-based server is attached to an IBM Tape Library with LTO-7 tape drives and Storwize V7000 storage devices. The customer is concerned about the liability of sending sensitive data off premises.

Which of the following solutions will satisfy the customer's concerns?

A. Enable the optional Storwize encryption feature.

B. Purchase the LTO Tape Encryption feature and Security Key Lifecycle Manager (SKLM)

C. Purchase an IBM Cryptographic Co-Processor.

D. Purchase IBM Multi-Cloud Data Encryption.

A customer has a mission-critical IBM i application running on a POWER9 processor-based server that requires eight processor licenses. For High Availability, a POWER9 CBU server is synchronized with the production server using PowerHA for IBM i.
