To reduce the attack vectors for a virtual machine, which two settings should an administrator set to false? (Choose two.)

• A.ideX:Y.present
• B.serial.present
• C.serial.enabled
• D.ideX:Y.enabled

An administrator is troubleshooting a performance problem with a virtual machine (VM). The VM and ESXi host configuration is as follows:
-The application which runs within the virtual machine is highly sensitive to memory latency, but
has low processor utilization. -The virtual machine has 6 vCPUs. -The ESXi host CPU topology has 2 Physical CPU Sockets, each with 8 Logical CPUs. -The ESXi host CPU has Hyper Threading enabled.
The administrator would like to improve CPU performance for this VM. Other VMs on the host have no performance issues. Which action should the administrator take to resolve the issue?

• A.Set the Advanced Parameter numa.PreferHT = 0 in the ESXi host configuration file.
• B.Set the Advanced Parameter numa.vcpu.preferHT = FALSE in the virtual machine configuration file.
• C.Set the Advanced Parameter numa.PreferHT = 1 in the ESXi host configuration file.
• D.Set the Advanced Parameter numa.vcpu.preferHT = TRUE in the virtual machine configuration file.

Which two statements are true regarding Storage Multipathing Plug-Ins? (Choose two.)

• A.The default Path Selection Policy is VMW_PSP_FIXED for iSCSI or FC devices.
• B.VMW_PSP_MRU is typically selected for ALUA arrays by default.
• C.VMW_PSP_FIXED is typically selected for ALUA arrays by default.
• D.The default Path Selection Policy is VMW_PSP_MRU for iSCSI or FC devices.

When troubleshooting a performance related issue, an administrator sees the following warning message on an ESXi Console:
Significant imbalance between NUMA nodes detected. Performance may be impacted.
Which action should the administrator take to correct this problem?

• A.Ensure that all RAM modules in the host are Error-correcting code (ECC) modules.
• B.Ensure that the physical server has the maximum amount of RAM modules that it can support.
• C.Ensure that the RAM modules are evenly balanced between processor sockets in the physical server.
• D.Ensure that all memory banks associated with CPU Socket 0 in the physical server are completely filled.

An administrator is unable to see performance statistics for only the Past Week performance data. The vCenter Server is using a Microsoft SQL Server Database.
What are three likely causes contributing to this issue? (Choose three.)

• A.The Vmware Performance Charts Service is stopped.
• B.The JDBC URL is incorrect in the vcdb.properties file.
• C.The stats_rollup_1_proc is not present.
• D.The Past Day rollup job is not present.
• E.Performance statistics are turned off.
