I was referring to VCAP-DCV 6.0 Deploy.. I already passed the exam and now I am VCIX-DCV 6.5 ( As I have given VCAP-6.5 Design earlier )

 

>> Feedback for VCAP-DCV 6.0 Delpy

 

1. The Lab was too slow, it test your patience really.

2. VMware should open internal centers as like Cisco does for CCIE

3. The question was pretty same as discussed earlier on this forum :

 

Live Lab:

 

You will manage the lab environment from the DC-RRAS virtual desktop. The console tab on the left side of the screen will provide console access to other management VMs if needed.

Note: The web client may not automatically refresh quickly enough after certain operations are performed. It is recommended after longer operations or if you receive an unexpected condition, that you refresh the web client to ensure you have the most up to date information.

 

The desktop provides all of the tools needed to manage your environment including:

 

· vSphere Web Client

· vSphere Client

· Windows Remote Desktop Client

· PuTTY (SSH Client)

· PowerCLI

· links to VMware documentation

 

You may navigate through the questions using the numbers at the top of each page or the Table of Contents located under "More Options" -- the questions are mostly independent of one another, and all scoring is performed after the exam is finished.

 

The Environment:

Note: The equipment you are working with during this exam is designed to simulate an actual datacenter environment. As such:

 

· Any changes you make during the exam will persist through each activity in the exam. Some activities are dependent on your successful completion of a previous activity. If you attempt an activity and do not see a prerequisite component for that activity in the environment, you may wish to examine your work on previous activities. You are allowed to go back at any time to a previous activity.

 

· Implementation or administration of vSphere components may vary from administrator to administrator. If during the course of completing an activity you wish to make minor changes or additions to the environment to conform with how you feel the activity should be implemented or administered, you may do so. Keep in mind that any adjustments to the environment persist through all activities. Any changes that are out of the scope of the activity should be avoided.

 

·Some items involve troubleshooting and have thus been intentionally set up incorrectly. These problems are usually indicated in the description of the item, and will typically need to be resolved as part of the item.

 

·Required virtual machine names and their associated credentials are presented as part of each question if they vary from the standard.

 

 

 

Standard credentials:

 

vCenter server login: [email protected]

 

Host and most appliance login: root

 

all passwords: VMware1! unless otherwise specified.

**********************************************************************************************

VSAN and VVOL storage have been provisioned in the QA environment for testing.

The storage team has requested some changes to the default configuration.

 

 

Requirements:

vCenter Server: vcsa-a.vclass.local

vCenter credentials: [email protected]

 

 

For any VSAN datastore:

 

Ensure flash read cache is 5% of the logical size of the object.

Ensure objects will always be provisioned

 

For the vsanDatastore:

 

Ensure objects are on at least 2 disks

Ensure at 10% of storage objects will be reserved upon VM provisioning.

Ensure number of failures to tolerate is set to 0.

 

 

Ensure the requirements are met with the minimum number of new objects.

****************************************************************

Management has asked for a proof-of-concept for a custom TCP/IP stack.

 

Requirements:

Host: esxi-a-05

TCP/IP stack: New-Stack

NIC: vmnic1

Algorithm: CUBIC

Max connections: 5000

IP Address: DHCP

 

Create a new TCP/IP stack on esxi-a-05 to meet the requirements.

 

Note: Do not reset the host as part of this excercise.

 

*********************

 

You suspect vSphere Replication Appliance on host esxi-a-02 is dropping packets received. Use ESXi shell command line tools to get comprehensive port statistics for the appliance since the last time the host was started.

 

Save these statistics to a text file /vmfs/volumes/ProdDS01/vRA-port-stats.txt on esxi-a-02.

 

net-stats -l

esxcli network port stats get -p 33554439

2) Create a new VMFS5 datastore on LUN 1 with the name ProdDS02

3) Add the volume to the existing datastore cluster Prod-DSCluster1

4) Configure Storage I/O Control so that disk latency does not exceed 45ms.

Configure resource pools in cluster HACluster for the Production, Development and Staging teams.

 

Requirements:

New Resource pools: Production, Development and Staging

3) Ensure the teams receive the correct percentages in HACluster regardless of future resources added to the cluster.

 

QUESTION 18

 

Migrations are failing between the hosts in the Compute-A-DTQA cluster.

2) Run the script to create the new VMs but do not power them on.

3) Save the fixed script as TemplateDeploymentFixed.ps1 in C:\Scripts.

 

Note: You are expected to correct the mistakes in the existing script, not write something new.

 

 

using Powercli deploy VM's on a particular cluster ( Creates a virtual machine by specifying a cluster and explicitly selecting the host, instead of allowing auto-selection of a target host.)
