During a cluster functionality test， and administrator performs a graceful stop for Node ’B’ in a three-node cluster. What is the expected state of the cluster after Node ’B’successfully completes？（） All cluster resources halt on Node ’B’，and one or both surviving nodes will gracefully acquire the resources.。 All cluster processes halt on Node ’B’，the cluster resources remain active，and the remaining nodes take no action.。 All cluster processes stay active on Node ’B’，cluster resources are halted，and the remaining nodes take no action.。 All cluster resources will stop，cluster processes halt on Node ’B’，and the remaining cluster nodes take no action.。
Companycom has several AS/400 servers in their IT infrastructure running V5R2 that they wish to consolidate. The customer wants to simplify their environment and install i5/OS on a p5 590 with 16 1.65GHz processors and 20 i5/OS partitions. The customer plans to use the Advanced Power Virtualization to share their storage, processors, and memory. What considerations and limitations should be reviewed with the customer before the purchase?（） Resources cannot be shared with an i5 partition when it is put on a pSeries. The i5 partition needs its own 9411-100 tower because of IOP. V5R3 OS or later is required. There is a maximum of two partitions in a 590.。 Resources cannot be shared between partitions when i5/OS is put on a pSeries. The i5 partition needs its own 9411-100 tower because of IOP. i5/OS can be at V5R2 or a V5R3. Currently only one i5 partition is allowed. 。 V5R3 is required for the i5 partitions. Virtual IO Server is not supported for the i5/OS partitions to share storage. Up to 10 i5 partitions per processor are allowed (a maximum of two processors for up to 20 partitions). 。 Processor and memory resources can be shared between AIX 5L, Linux and i5/os partitions. i5/OS needs to be at V5R3, and Virtual IO Server is not supported for the i5/OS partition to share storage. On a 1.65 GHz POWER5 p5 590 there is a maximum of one partition.。
Company.com with a newly installed cluster has been checking the logfiles to determine if the cluster has had any recent activity. The non-IP RS232 heartbeat connection seems to be having a difficulty. The serial network goes down，and then a couple of minutes later comes back up again. This pattern is repeated many times in the log. If this system was installed without regard to best practices， what is the most likely problem with the serial network？（） The serial port is malfunctioning and needs to be repaired.。 The baud rate is incorrectly specified in the AIX devices configuration.。 The serial port is not a port approved to support HACMP heartbeat traffic.。 The baud rate is incorrectly specified in the HACMP interface configuration.。
While a user is compiling a C program, "vmstat 120 10" is run to determine the cause of a performance problem. Using the vmstat output as shown in the exhibit, which of the following conclusions is most appropriate to draw?（） There is a file I/O bottleneck.。 There are too many open files. 。 There appears to be a buffer shortage. 。 There is a paging space I/O bottleneck.&e。
