Ch 11 Flashcards
- Which of the following can be used to restart the ESXi host agent? (Choose all that apply.)
A. DCUI
B. ESXi Shell
C. vSphere Client
D. All of these
A and B. The ESXi Shell can be used to restart the host agent service. The DCUI Troubleshooting Options menu item can also be used to restart all management agents, including hosts.
- You just deployed vCenter Operations Manager, and you want to change both the default admin and root passwords. Which of the following is a valid password that could be used with either of these accounts?
A. password
B. P@ssword
C. passw0rd
D. p-ssw-rd
C. The admin and root passwords must be a minimum of eight characters and include at least one letter and one digit.
- When viewing the Tasks & Events tab in the vSphere Client, you notice that there are a limited number of entries, and the information available does not go back far enough. What setting could be used to adjust the number of entries?
A. This is not possible.
B. Edit > Client Settings > List tab.
C. Filtering
D. vCenter Server Settings > Administration > Statistics.
B. The number of entries displayed in the tasks and events lists in the vSphere Client can be adjusted using the Edit > Client Settings > Lists tab.
- Which of the following is defined as the percentage of time a VM was not provided CPU resources but was ready to run?
A. %SYS
B. %WAIT
C. %USED
D. %RDY
D. %RDY or CPU Ready is used to measure the percentage of time a VM was ready to run but was not provided with CPU resources.
- You need to collect resxtop data for two minutes. This data will be used in Perfmon on a Windows guest. Which of the following commands should be used?
A. resxtop –server –vihost –username \ -b -d 3 -n 120 > resxtop-export.csv
B. resxtop –server –vihost –username \ -b -d 120 -n 1 > resxtop-export.csv
C. resxtop –server –vihost –username \ -b -d 2 -n 60 > resxtop-export.csv
D. resxtop –server –vihost –username \ -b -d 1 -n 120 > resxtop-export.csv
C. The -d switch is the delay between statistics snapshots, and the -n switch is used to specify the number of iterations. Option C will perform 60 iterations at 2-second intervals, captuing 2 minutes of data.
- You created a vCenter Server alarm at the root vCenter Server level to monitor a single virtual machine for the snapshot space used. You are now getting warnings from several VMs. What is the best way to solve this problem?
A. Re-create the rule at the virtual machine object level.
B. Exclude the virtual machines you don’t want to see from the rule.
C. Move the rule to the host level.
D. None of these.
A. Alarms are inherited down the chain of inventory objects, so the only way to solve this problem is to re-create the alarm at the VM object level.
- Which file type is used to upgrade vCenter Operations Manager?
A. .zip
B. .tar.gz
C. .vib
D. .pak
D. vCenter Operations Manager can be upgraded by downloading a .pak file from Vmware and applying it via the vCenter Operations Manager Administration portal.
- You collect metrics for your vSphere environment. You see %DRPRX has a value of 1. Which of the following is most likely the problem?
A. CPU.
B. Network.
C. Disk.
D. There is no problem.
B. %DRPRX indicates that network receive packets are being dropped. This is a likely indicator of a network problem.
- Which of the following is defined as the average amount of time in milliseconds a device takes to service a single I/O request?
A. DAVG/cmd
B. GAVG/cmd
C. KAVG/cmd
D. None of these
A. The DAVG/cmd metric is the average amount of time in milliseconds a device takes to service a single I/O request. The device includes the vmhba, the storage device, and any devices between.
- Which of the following are major badges in vCenter Operations Manager? (Choose all that apply.)
A. Workload
B. Risk
C. Efficiency
D. Density
B and C. Health, Risk, and Efficiency are the three major health badges in vCenter Operations Manager. Workload and Density are two of the eight minor badges.
You notice an alarm on your vCenter Server that states vSphere HA Host Status. What is the most likely cause of this alarm?
A. Host hardware power supply failure
B. Host hardware NIC failure
C. Host hardware memory failure
D. Host hardware Fiber Channel HBA failure
B. vSphere HA alarms could likely be the result of a management network communication failure.
- Which of the following is an unsupported IP allocation scheme for use with the vCenter Operations Manager vApp?
A. DHCP
B. Static - Manual
C. Transient - IP Pool
D. NAT
C. The tansient IP allocation scheeme is unsupported by vCenter Operations Manager.
- Which of the following can be scheduled using the scheduled tasks feature in vCenter Server? (Choose all that apply.)
A. Cloning a VM
B. Migrating a VM
C. Adding a host
D. Deleting a VM
A, B and C. Cloning a virtual machine, migrating a virtual machine, and adding a host are all tasks that can be scheduled in vCenter Server. There is no scheduled task to delete virtual machines.
- You created a vCenter Server alarm with multiple trigger types and an action to send email. One of the triggers should have fired by now, but you have not received any emails. You are receiving emails from other alarms. Which of the following is most likely the reason?
A. The Trigger If All Of The Conditions Are Satisfied option was used.
B. The Trigger If Any Of The Conditions Are Satisfied option was used.
C. SMTP is not configured in the vCenter Server settings.
D. Alarms cannot have multiple trigger types.
A. If the Trigger If All Of The Conditions Are Satisfied option is used, then each trigger type must have the condition met before the trigger will fire. Remember that the more trigger types that are added, the more complex the alarm becomes.
- Which of the following are reaquired to configure SMTP in the vCenter Server settings? (Choose two.)
A. IP address of SMTP server
B. Port number of SMTP server
C. SMTP server authentication information
