An administrator has recently upgraded their Update Manager infrastructure to vSphere
5.x. Several hosts and virtual machines have not been upgraded yet.
Which vSphere component when upgraded will have the least impact to the existing environment?
- A. Virtual Machine Hardware
- B. ESX Hosts
- C. VMFS datastores
- D. VMware Tools
Answer : D
Explanation:
VMware Tools isn't a single application but a set of drivers, services and user processes that's installed in a guest operating system. They add a wide assortment of functionality to
VMware infrastructures -- everything from improving color depth and video resolution in the vSphere Client to memory optimization.
Typically, an outdated version of VMware Tools doesn't have an immediate impact. But with every update to vSphere, you'll likely have to update VMware Tools on every virtual machine.
Users of an application are reporting performance issues. The following performance values are observed in the vSphere Web Client:
-> Host CPU utilization is 90%
-> Virtual Machine memory utilization is consistently greater than 90%
-> CPU Ready values are higher than 20%
What could be the cause of the application performance issue?
- A. The host is lacking the CPU resources required to meet the demand.
- B. The host is lacking the memory resources required to meet the demand.
- C. The virtual machine is lacking the CPU resources required to meet the demand.
- D. The virtual machine is lacking the memory resources required to meet the demand.
Answer : A

- A. 1492
- B. 1500
- C. 9000
- D. 9089
Answer : B,C
Refer to the Exhibit.
-- Exhibit --
A 4 GB Memory virtual machine is experiencing extended memory issues, as shown in the Exhibit.
What potential issues could be attributed to this memory pressure?
- A. A limit is imposed on the virtual memory of this virtual machine.
- B. The Balloon driver has been uninstalled.
- C. A limit has been imposed on the Virtual CPU of the virtual machine.
- D. Storage IO control has been enabled for the virtual machine causing the swapped memory.
Answer : A,B
An administrator is tasked with performing a vMotion migration of a virtual machine.
The virtual machine is configured as follows:
-> vSphere Flash Read Cache (vFRC) enabled
-> Is part of a Distributed Resource Cluster (DRS) Cluster
Which two statements are true? (Choose two.)
- A. Each ESXi host in the cluster supports multiple virtual flash resources.
- B. Each ESXi host in the cluster supports one virtual flash resource.
- C. DRS treats powered-on virtual machines with Flash Read Cache as having a preferred affinity to their current host and moves them only for mandatory reasons.
- D. DRS treats powered-on virtual machines with Flash Read Cache as having a required affinity to their current host and does not move them.
Answer : B,C
? An administrator wants to add a web server to an existing multi-tier application consisting of three virtual machines:
-> A web server
-> A database server
-> An application server
The web server should be added to the application when the primary web server reaches:
-> 70% vCPU utilization
-> 55% active memory
Which option will achieve this result?
- A. Create a virtual machine alarm with an action to run a script that starts a new instance of the web server.
- B. Create a host cpu and memory alarm with an action to run a script that starts a new instance of the webserver.
- C. Configure HA application monitoring for the web server and set it to trigger deployment of a new instance of the web server.
- D. Configure Fault Tolerance on the virtual machine and leave the secondary machine disabled until needed.
Answer : A
A High Availability (HA) cluster is configured to respond to a given number of host failures. The cluster contains virtual machines configured with these settings:
-> VM1 has a 1GHz CPU reservation and no Memory reservation
-> VM2 has a 2GHz CPU reservation and no Memory reservation
-> VM3 has no CPU reservation and no Memory reservation
Given this information, what is the correct slot size for the cluster?
- A. The CPU Reservation should be set to 32MHz and the memory reservation should be set to 32MB plus memory overhead.
- B. The CPU reservation should be set to 1 GHz and the memory reservation should be set to 0MB plus memory overhead.
- C. The CPU reservation should be set to 2 GHz, and the memory reservation should be set to 0MB plus the virtual machine memory overhead.
- D. The CPU reservation should be set to 2 GHz, and the memory reservation should be set to 32MB, plus the virtual machine memory overhead.
Answer : C
An administrator enables vSphere High Availability (HA) on an existing cluster with a large number of hosts and virtual machines. The administrator notices that the setup of vSphere
HA on some of the hosts is failing.
What step, if taken, might resolve this issue?
- A. Increase the value of the config.vpxd.das.electionWaitTimeSec setting.
- B. Set the value of vpxd.das.aamMemoryLimit to 256.
- C. Set the value of the das.useDefaultIsolationAddress setting to False.
- D. Increase the value of the das.iostatsinterval setting.
Answer : A
An administrator receives a report that no real time statistics are available for a virtual machine in the vCenter Server inventory.
Which two statements indicate likely causes of the problem? (Choose two.)
- A. The virtual machine is powered off.
- B. The host containing the virtual machine is disconnected from vCenter Server.
- C. There is insufficient real time data to display the information.
- D. The vCenter Server service is not running.
Answer : A,B
VMware tools is failing to install on a Microsoft Windows virtual machine.
What are two possible situations that would prevent the installation? (Choose two.)
- A. The VMware tools installation media is corrupt.
- B. The incorrect Operating System was selected in the virtual machine options.
- C. The software prerequisites have not been installed.
- D. The prerequisite services have not been started.
Answer : A,B
What is true regarding datastores on ESXi 6.x?

- C. NFS datastore can be concurrently mounted using NFS 4.1 on one host and NFS on another
- D. NFS 3.0 datastore does not support Fault Tolerance (FT)
Answer : A
