horizon view interview questions

VMware, a pioneer in virtualization and cloud computing, offers desktop and network virtualization solutions. The technological world has changed from a physical to a software-based virtual one thanks to VMware.

The need for subject matter experts is growing daily in the market as a result of the adoption of a virtual environment to consolidate the hardware infrastructure. An experienced workforce is needed to manage and maintain an organization’s business. To choose the best talent available on the market and expand an organization’s business, professionals are chosen through a variety of technical and HR processes.

The following scenario-based interview questions and responses for skilled IT administrators with up to five years of experience are provided to gauge the applicant’s technical and practical knowledge.

#1. The vSphere Web Client of an administrator is used to connect directly to the ESXi host. Which ports are required for this purpose?.

Typically, vCenter Server connections are made using the vSphere Web Client, and ESXi host connections are made using the VClient. But you can also connect to vCenter Server using the vSphere Web Client; however, you’ll need to open the 443 TCP, 902 TCP and UDP, and 903 TCP ports from the Security Profile for this.

#2. The clock time of an ESXi 6. x host is not correct. What should an administrator do to correct this issue?.

Change the host’s time using the vSphere client, then make the necessary changes to the NTP settings in the /etc/ntp file to correct the time on the ESXi host. conf file.

#3. A manager wishes to terminate the host running ESXi. Which Direct Console User Interface option would be used to carry out this task?

Pressing the F12 key will cause the host for Direct Console User Interface (DCUI) to shut down.

#4. The ESXi host can be accessed by an administrator through vCenter Server using the vSphere Web Client, but not directly through the VClient. What should he do to access ESXi host directly?.

We should verify that Lockdown is not enabled if the ESXi host connected to vSphere Web Client is being accessed but cannot be accessed directly. If it is enabled, we should be disabled. Because if Lockdown is enabled, you can only access ESXi hosts through vCenter Server and you cannot access any hosts directly.

#5. The VMware Certificate Authority (VMCA) is intended to be used as an Intermediate Certificate Authority (CA) by an administrator. He has already replaced the Intermediate CA’s Root Certificate and Machine Certificates. What should he do next?.

The following two actions must be carried out after replacing the root certificate and machine certificate (intermediate CA).

#6. What should an administrator do if Strict Lockdown Mode is enabled on an ESXi host in order to enable ESXi Shell or SSH access for users with administrator privileges?

The users are added to the exception users list by the administrator, who also turns on the service that permits ESXi Shell or SSH access.

#7. SSO is an essential component of the vCenter Server. Which SSO component issues Security Assertion Markup Language tokens?.

#9. When a Content Library is deleted, what happens to the files that are present on shared storage?

#11. The vSphere Web Client can be used to log in as a windows domain user. What needs to happen in order for this feature to be functional and available?

Users may use Windows session authentication to sign into the vSphere Web Client with the permission of the administrator. Install the vSphere Web Client Integration browser add-on on each computer where a user will sign in for this reason. Windows must be launched with the users’ Active Directory user accounts already logged in. Additionally, a valid Identity Source in Single Sign-On for the users’ domain must be created by an administrator.

#12. An administrator wants to use the vSphere Client to clone a virtual machine. Which explains why the Clone option is missing?.

You can connect to vCenter Server and clone a VM using either the vSphere Web Client or the VClient. A VM cannot be cloned if you are directly connected to an ESXi host.

A virtual machine’s BIOS state is stored in an nvram file. If it is deleted for some reason, then, . When the virtual machine is powered on, a new nvram file will be created.

#14. An administrator wants to connect the vSphere 5. 5 Client to ESXi 6. x host. What will occur?.

If the administrator tries to connect the vSphere 5. 5 Client to ESXi 6. The procedure will ask the administrator to run a script to upgrade the vSphere Client on the x host.

#15. Which secondary Private VLAN (PVLAN) configuration can send data to an isolated PVLAN?

#17. What will happen if the software FCoE storage experiences an all paths down (APD) event?

You can update using vSphere Update Manager (VUM), the esxcli command-line tool, and vSphere Auto Deploy.

The latest version of VMware Tools should be installed, a backup or snapshot of the VM should be made, and the VM should be stored on a VMFS or NFS datastore before upgrading the hardware.

#20. vCenter Server up-gradation fails at the vCenter Single Sign-On installation. What should you do to complete the upgrade process?.

Please manually restart the VMware Directory service to make sure it can stop before upgrading the vCenter Server. You can begin the vCenter Server upgrade process if it was manually stopped.

Client Integration Plugin (CIP) will be installed in either scenario: vCenter Server Appliance (vCSA) upgrade or new installation.

#22. The following error is displayed after deploying a PSC and vCenter Server is not installed:

Make sure the clocks on the host machines running the PSC, vCenter Server, and the vSphere Web Client are synchronized if this error occurs. Additionally, make sure that port 7444 is not being blocked by a firewall between the PSC and the vCenter Server.

#23. When trying to install vCenter Server on a Windows virtual machine that an administrator installed Windows Server 2008 on, what happens?

vCenter Server installation requires 64bit Windows OS to install. It won’t install if you try to do so on Windows Server 2008, and the installation will fail. Windows Server 2008 R2 or a later version of the Windows OS will have vCenter Server installed.

vFlash Read Cache was first in vSphere 5. 5, and the minimum Virtual Hardware version for vSphere 5. 5 is version 10.

#25. The ESXi host is added in vCenter Server, but the vSphere Web Client is not responding. Which port needs to be opened if a firewall is the cause of this problem?

If the administrator sees no response of added ESXi 6. The problem is brought on by a network firewall that is blocking traffic on host x in vCenter Server. He should then make sure that a firewall is not blocking port 902 (UDP). If this occurs, select the relevant ESXi host in vCenter Server’s vSphere Web Client and enable the port from the Security Profile.

#26. Suppose a VM is unexpectedly powered off. Which VM logs files should be taken into account when troubleshooting the problem?

If it happens, an administrator should check vmware. log and hostd. log log files to troubleshoot the issue.

A host failure for VMware High Availability could result from a VM appearing in an orphaned state. Additionally, the virtual machine was directly unregistered on the ESXi host.

It denotes that the ESXi host does not have enough memory to finish upgrading from ESXi 5 5 to ESXi 6. x.

#29. The following error message is seen when attempting to remove a host from a vSphere Distributed Switch (vDS):

It is ensured that the VMkernel network adapters on the vDS are not in use before removing it. The error message with the resource ID mentioned above will appear if any of the vDS resources are being used.

#30. An administrator attempts to monitor and record network traffic for a virtual machine (VM), but the expected traffic is not visible in the packet capture tool. What should he do to resolve the problem?.

Enabling promiscuous mode on the appropriate port group is what an administrator should do if he needs to record network traffic for a virtual machine. Then, you can use any networking traffic capturing tool to capture the network traffic.

#31. Three of the six nodes in the fault domain and the vSAN Cluster are moved into the fault domain. A one-member node of the fault domain fails. What will happen to the two nodes that are still present in the fault domain?

The remaining two fault domain members will be treated as failed when a member node of the fault domain fails.

At the vSAN Cluster level, a fault domain is set up, and nodes will be added to it. The remaining members of the fault domain will also be considered to have failed if any member node fails for any reason.

#33. A VM storage activity on an ESXi 6 has been noticed. A VM storage activity on another host that accesses the same VMFS Datastore is being adversely affected by the x host. Which action would mitigate the issue?.

Storage IO Control (SIOC) should be enabled to prevent one virtual machine’s storage activity from influencing that of another. When there is competition for I/O resources, Storage I/O Control offers much-needed control of storage I/O and should be used to make sure that the performance of your critical VMs is not impacted by VMs from other hosts.

This command will show all active VIBs (vSphere Installation Bundle). A VIB is a group of files, similar to tarballs or zip archives, that have been packaged together to make distribution easier.

#35. Which counters will be used to show CPU contention when troubleshooting a VM’s CPU performance issues?

The ESXTOP tool is used to test an ESXi host’s performance in terms of memory, CPU, and network utilization. VMware administrators have access to a great tool to analyze performance problems. You’ll need the vSphere Client to configure ESXTOP, and putty and SSH sessions must be enabled. The counters %RDY, %MLMTD, and %CSTP are utilized for CPU performance testing.

#36. To diagnose CPU performance issues, an administrator tries to run esxtop while enabling SSH and using putty, but no output is shown. How to resolve this issue?.

Press f to display output in ESXTOP, then put an asterisk next to each field you want to see.

#37. When memory usage reaches 80%, an administrator wants to use vCenter Server to monitor the virtual machines (VMs) running on the host. What steps should a vCenter Server administrator take to achieve this?

A vCenter Server alarm will be created to track a VM’s memory usage when it reaches 80% and set an action to email the notification.

#38. An administrator created a DRS cluster, and it became unbalanced. What are likely causes to become unbalanced?.

When Affinity rules prevent VMs from being moved, the DRS cluster may become unbalanced. And when a device is mounted to a VM, vMotion from one host to another is not possible.

#39. A PSC’s two vCenter Servers were set up by an IT administrator, who now needs to give a user access to all environments. What level of access is necessary to enter each environment?

#40. An administrator created 10 ESXi 6. x hosts for a new Test/Dev cluster using Auto Deploy, and all hosts are set up to get their IP addresses from DHCP. Which DCUI selection should the administrator select in order to extend the hosts’ DHCP lease?

The Direct Console User Interface (DCUI) option’s “Reset Management Network” is used to update the hosts’ DHCP lease.
