IBM IBM Certifications C1000-031 Questions & Answers

• Question 81:

  A customer has ordered a Power System E980. The system has been built, but cannot be shipped.

  What would prevent the system from being shipped?

  A. The mandatory pre-install TDA has not been completed.

  B. The IBM System Support representative has not completed the pre-install site visit.

  C. The opportunity owner has not released it.

  D. A pre-sale TDA discovered correctable issues that have not been corrected.

  Correct Answer: D

• Question 82:

  A customer would like to add a second HMC to an environment which consists of multiple POWER8 and POWER9 processor-based systems.

  Which of the following is a requirement for both HMCs to be able to manage all the systems?

  A. Both HMCs must be at the same version of HMC Code.

  B. Both HMCs must be on the same HMC VLAN.

  C. All the POWER8 processor-based systems must be at the same firmware level.

  D. Each HMC must be on a dedicated HMC VLAN.

  Correct Answer: D

  A switch can be partitioned to create a VLAN dedicated to HMC to managed server communication. If HMCs are configured as DHCP servers, there must be only one HMC on each VLAN! If dual HMCs are attached for redundancy, it is unwise to connect the HMCs to two VLANs in the same switch, because if the switch fails both HMCs lose connectivty, thereby defeating the HMC redundancy.

• Question 83:

  Which of the following statements is true regarding Dynamic Logical Partitioning (DLPAR)?

  A. In a disaster, it will immediately move active LPARs from a local system to a remote system, over the network with only a pause in service.

  B. In a disaster, it will immediately move active LPARs from a local system to another local system, using a common SAN, with only a pause in service.

  C. It enables the relocation of resources such as CPU and memory between LPARs as required, without an interruption in service.

  D. It will automatically allocate an unlicensed processor to an LPAR to replace one that has reached the threshold for errors.

  Correct Answer: D

• Question 86:

  A customer is comparing a Power Systems solution with an x86 solution for big data analytics.

  Which no-charge IBM analysis is available to justify the value of IBM Power Servers compared to x86 solutions?

  A. IT Economics Study (Eagle Study)

  B. Performance Navigator

  C. System Planning Tool

  D. Workload Estimator

  Correct Answer: D

  The IBM Systems Workload Estimator is a web-based sizing tool for IBM Power Systems, System i, System p, System x, IBM Flex Systems, and IBM PureFlex Systems. You can use this tool to size a new system, to size an upgrade to an existing system, or to size a consolidation of several systems. The Workload Estimator (WLE) allows measurement input to best reflect your current workload and provides a variety of built-in workloads to reflect your emerging application requirements. Virtualization can be used to yield a more robust solution. The Workload Estimator will provide current and growth recommendations for processor, memory, and disk that satisfy the overall client performance requirements
