An administrator has a virtual machine configured with the following settings:
ESXi version: 5.1 CPU: vCPUs 6 Memory: 48GB Hardware version: 7 VMware Tools: Installed
Which two actions must the administrator take in order to utilize vNUMA? (Choose two.)
A. Upgrade the ESXi host to vSphere 5.5 or later.
B. Upgrade to Virtual Hardware version 8.
C. Configure numa.vcpu.min to 5
D. Configure numa.vcpu.min to 6
An administrator has migrated a vCenter Server Appliance from version 5.5 to version 6.x. During the migration, the administrator selected DHCP for the appliance and obtained a hostname from the DHCP server. The administrator adjusts the hostname after the migration and uses a static IP and hostname.
What should the administrator do immediately after this change to prevent service failures?
A. Regenerate the SSL certificates.
B. Re-register components to Single Sign-On.
C. Update the /etc/hosts file.
D. Execute the command services.restart vmware-vpxd.
An administrator is unable to start the vCenter Server service. The vpxd.log file shows this service failure:
[13308 error `Default' opID=622892-371bf717] CoreDump: Unable to write minidump [13308 error `Default' opID=622892-371bf717] error -2147024784 : There is not enough space on the disk.
What is preventing the start of the service?
A. Insufficient space on the vCenter Server
B. Insufficient space on the Database Server
C. Insufficient space on the VMFS volume
D. Insufficient space on the ESXi ramdisk
After successfully adding a new ESXi 6.x host to vCenter Server, an administrator sees it as Not Responding in the vSphere Web Client interface a few minutes later. If the issue is caused by a network firewall blocking traffic, which port must be opened to correct this specific problem?
A. 443 (TCP)
B. 443 (UDP)
C. 902 (TCP)
D. 902 (UDP)
An administrator notices that 8 out of 10 virtual machines have memory ballooning and swapping. However, virtual machine 9 is not ballooning or swapping and virtual machine 10 is not ballooning but is swapping. Which two statements explain the behavior of virtual machine 9 and virtual machine 10? (Choose two.)
A. Virtual machine 9 has a 100% memory reservation.
B. Virtual machine 10 has a memory limit configured.
C. Virtual machine 9 has memory shares set to HIGH.
D. Virtual machine 10 does not have Vmware Tools enabled or installed.
An administrator notices that the time on an ESXi 6.x host is incorrect.
Which two actions should the administrator take to correct this issue? (Choose two.)
A. Modify the time for the host using the vSphere client.
B. Correct the NTP settings in the /etc/ntp.conf file.
C. Configure NTP from the Direct Console User Interface.
D. Use the vicfg-ntp command from the vSphere Management Appliance.
Which three troubleshooting actions should an administrator take to address slow performance when deploying a virtual machine template? (Choose three.)
A. Increase network throughput by adding additional uplinks to the vSwitch.
B. Change the destination datastore or volume for the virtual machine template.
C. Configure a Provisioning Traffic vmkernel port to perform the deployment operation.
D. Reduce the size of the virtual machine template's virtual disk.
E. Deploy the virtual machine template to the cluster and allow Distributed Resource Scheduler to register the virtual machine.
A virtual machine is exhibiting these symptoms:
Memory usage is constantly high (94% or greater) or constantly low (24% or less). Free memory is consistently 6% or less and swapping frequently occurs
Which three solutions could correct this problem? (Choose three.)
A. Verify that Vmware Tools is installed on each virtual machine.
B. Decrease the memory reservation setting, if higher than active memory.
C. Add physical memory to the host.
D. Disable the balloon driver in each virtual machine.
E. Create a memory limit for each virtual machine.
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.vcpu.preferHT = TRUE in the virtual machine 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.PreferHT = 0 in the ESXi host configuration file.
Attempting to update an ESXi 6.x host using the following command:
esxcli software vib update –d update.zip
Generates the following error:
Could not download from depot at /tmp/index.xml, skipping ((`/tmp/index.xml', `', "[Errno 4] IOError:
What action should be taken to correct the problem?
A. Add the full file path to the command.
B. Use the update option instead of install.
C. Use the switch –d instead of –v.
D. Replace esxcli with esxupdate.
