IBM C4040-109 Online Questions & Answers

• Question 51:

  An administrator is attempting to configure a new deployment of 56 POWER7 Blades across 4 IBM BladeCenter H chassis. Each blade will be installed with an IVM and 2 LPARs.IVM is installed and the administrator checks that both LHEA ports are reporting a Link State of "Up." 2 LPARs are created and the network traffic balanced by allocating one LHEA port to the first LPAR, the second port to the other. After successfully installing the first LPAR via NIM, the administrator finds the second LPAR fails to netboot. What should the administrator verify on the BladeCenter Chassis?

  A. That 4 power supplies (PSU) have been installed.
  B. That both the external LHEA ports have been cabled.
  C. That a secondary I/O module has been installed and cabled.
  D. That the Multi-Core Scaling (MCS) attribute is correctly set on both LHEA ports.
  C. That a secondary I/O module has been installed and cabled.

• Question 52:

  Following the reboot of one VIO server (VIOS) in a redundant configuration, a client is showing failed disk paths on some channels. What is the most likely reason the disk paths have failed?

  A. MPIO drivers have not been installed on the client.
  B. VIOS Fibre Channel adapters have created a private loop as the attribute init_link has not been set.
  C. vSCSI and disk attributes vscsi_err_recov, vscsi_path_to and hcheck_interval have not been configured.
  D. Disk attributes on VIOS for the reserve policy on the disk is not set to no_reserve.
  C. vSCSI and disk attributes vscsi_err_recov, vscsi_path_to and hcheck_interval have not been configured.

• Question 53:

• Question 54:

  An administrator has installed a new HMC and needs remote command line access. The option for "Remote Command Execution" has been selected, but ssh still isn't working. What action must be performed to allow ssh connections?

  A. Ensure the option for "Remote Operation" is selected.
  B. Under "Manage Certificates", create a New Certificate.
  C. Use the ssh-keygen utility to generate a new key and add that key to the remote host.
  D. Add "Secure Shell" to the list of Incoming Protocols in the Firewall Settings.
  D. Add "Secure Shell" to the list of Incoming Protocols in the Firewall Settings.

• Question 55:

  An administrator is using a Power Systems server with a Virtual IO server to host a large number of short-lived development LPARs. All disks are presented using virtual Fibre Channel adapters with NPIV enabled. When trying to create a new

  LPAR, the following error message is displayed:

  HSCLA4C5: There are no WWPNs remaining for this managed system that can be assigned to a virtual Fibre Channel adapter.

  Which action will resolve the error?

  A. Upgrade the server to PowerVM Enterprise Edition.
  B. Change the WWPN prefix configured in the Virtual I/O Server.
  C. Reuse the WWPNs of decommissioned LPARs.
  D. Use Capacity On Demand to generate an activation code that provides more WWPNs.
  D. Use Capacity On Demand to generate an activation code that provides more WWPNs.

• Question 58:

  Which of the following statements regarding the implementation of Multiple Shared Processor Pools (MSPPs) is correct?

  A. MSPPs allow for both IBM and third party applications to be licensed for a subset of physical processors.
  B. MSPPs allow the restriction of transferring available processor cycles from one set of LPARs to another.
  C. MSPPs allow processor capacity consumption to be restricted to a set of LPARs.
  D. MSPPs allow for physical sets of processors to be reserved for specific sets of LPARs.
  C. MSPPs allow processor capacity consumption to be restricted to a set of LPARs.

• Question 59:

  An administrator has configured NTP on the HMC using the hostname of a public NTP server and restarts the HMC. When the /var/log/ntp file is checked, the synchronization with the time server has not occurred. What is the most likely cause?

  A. The firewall needs to be opened for xntp.
  B. The "chhmc -c xntp -s start" command needs to be run.
  C. The time server needs to be specified by IP address on an HMC.
  D. NTP has been configured on the private network.
  A. The firewall needs to be opened for xntp.
