1 Power Systems with POWER8 Scale-out Technical Sales Skills V1 1. An ISV develops Linux based applications in their heterogeneous environment consisting of both IBM Power Systems and x86 servers. They are considering optimizing operations by offering developers a self-service user interface for automated provisioning of new Linux images. Which of the following tools will satisfy their requirement? A. VMControl B. PowerKVM C. IBM Cloud Manager with OpenStack D. IBM PowerVC Standard Edition Managing PowerKVM 2. Which feature is included with Quick to Order pre-defined configurations on the LC models? A. 64 GB of memory B. Software preload C. Two power supplies D. 3-Year, 9x5 Software Maintenance 3. A customer wants to make use of the Server Flash Caching function on their POWER8 machine. Which operating system supports this function? A. AIX 7.2 B. IBM i 7.2 C. Red Hat Enterprise v7.2 D. SUSE Enterprise v12 4. SPEC (Standard Performance Evaluation Corporation - spec.org) published a benchmark called specvirt_sc2013 designed to measure the amount of pre-defined virtual machines a server can run simultaneously. The following results were achieved, for a POWER S824 and a HP DL560 Gen8: Based on the results, IBM Power: A. was able to achieve almost two times more VMs per server than HP. B. was able to achieve almost two times more VMs per core than HP. C. was able to achieve two times more VMs per socket than HP. D. can pack 1.5 times more VMs per rack unit than HP.

2 5. How many PCIe Gen3 I/O Expansion Drawers can be attached to an S812LC server? A. Zero B. One with one fanout module C. One with two fanout modules D. Two with two fanout modules 6. A customer requires two IBM systems and two DS8870 storage units to be connected in a cross-coupled active - active configuration between two different sites. What is the technology that allows this type of configuration? A. HyperSwap B. Cluster Aware AIX C. IBM Spectrum Protect D. Shared Storage Pool 7. Which statement describes an advantage of the ability to use Shared Storage Pools (SSPs)? A. They reduce the total required storage in the organization by removing duplicate files. B. They reduce the overall storage administration efforts by allocating once and distributing as needed. C. They increase the overall read/write speed across the organization by mixing different storage technologies. D. They increase the total number of OS instances that can simultaneously write to the same file by duplicating the files. 8. A customer currently has VIO Server and non-vio Server partitions on a POWER8 system. What is the benefit of using SR-IOV adapters? A. They are dedicated to non-vio Server partitions. B. They eliminate the need for the VIO Servers. C. They can be used by VIO Server and non-vio Server partitions. D. They force the non-vio Server partitions to share resources through VIO Servers. 9. Which of the following Power Systems supports the highest density of Graphics Processing Units (GPUs) per rack? A. S824L B. S822L C. S822LC D. S812LC 10. With Scale-out servers, what is the maximum number of power distribution units (PDUs) that can be installed in a 7014-T42 rack without horizontal mounting? A. 0 B. 2 C. 4 D. 6

3 11. Which of the following features is natively supported with both PowerVM and PowerKVM? A. NPIV B. HMC Management C. Live Partition Mobility D. Memory Compression 12. A customer wants to install a POWER8 tower system at a remote site. The system will run Red Hat Linux. Which system satisfies the requirement? A. S814 B. S822L C. S812L D. S There is a dedicated memory controller in each of the CDIMMs. How can this capability increase the platform RAS? A. Multiple memory controllers allow for faster Live Partition Mobility operations, increasing the speed that a server VMs can be evacuated in case of failure B. By having multiple CDIMMs, a server has multiple integrated memory controllers, allowing for failure of a memory controller without impacting the server operations. C. Having a memory controller on the memory modules allow for CAPI enabled adapters to bypass the CPU and access data directly into memory forcing cache to write to disk when a failure is detected. D. Besides their standard functions, memory controllers also perform memory scrubbing to identify and correct single bit soft-errors on the memory modules and inform the Hypervisor of faulty memory modules. 14. When creating a partition that will be using Live Partition Mobility, which of the following is a valid configuration? A. All the storage, Ethernet and backup I/O must be virtualized with VIO Server. B. Both VIO Servers must be on the same Ethernet Subnet on a class "C" network. C. Each VIO Server needs a dedicated HMC assigned to it where the HMCs are set up in Dual Mode. D. The boot LUNS for each partition must be kept on different SANs and must be accessed by only one partition at any time. 15. A customer has two Power 570 servers that need to be replaced to accommodate company growth. The first server runs a transactional workload with high server usage during the day (8am-8pm) The second server runs analytic queries based on the transactional data during the night (10pm-6am). A technical sizing analysis determined that each server would require (18) POWER8 3.52GHz cores and 160GB RAM, considering the needed growth. What would be the most cost-efficient (Total Cost of Acquisition) way to satisfy the customer needs?

4 A. (2) new Power S824 with 20 cores and 192GB RAM each. B. (1) new Power S824 with 36 cores and 384GB, virtualized with capped LPARs. C. (1) new Power 770 with 36 active cores and 384GB active, virtualized with capped LPARs. D. (1) new Power S824 with 24 cores and 384GB and DLPAR CPU resources among LPARs. 16. What is the maximum number of partitions that can be moved concurrently using Live Partition Mobility (LPM) with the HMC 7042-CR8? A. 8 B. 16 C. 64 D. 128
