VMware 3V0-31.22 Exam - Topic 2 Question 1 Discussion

Actual exam question for VMware's 3V0-31.22 exam

Question #: 1
Topic #: 2

TASK 12

As the Cloud Administrator, you have been tasked to update the Atlas App cloud template in the Atlas project. Perform the following tasks:

1. Edit the existing cloud template Atlas App. such that it is a multi-tier application that meets the following requirements:

* 2 Web servers

* 1 Database server

* The Database server is always built before the Web servers

* 2 NSX Networks:

o The first network should use the NAT feature

* Resource Name: external

* Second network should be an existing network

* Resource Name: internal o All networks should be restricted to use only the Atlas project networks

o The internal network should be restricted to use only the nsx-atlas-existing NSX network

* Both the web and db VMs should be connected to the internal network

2. Add an NSX load balancer to provide access from the outside to the two Web servers:

* Resource Name: IbWeb

* Port: 443

* Protocol: HTTPS

3. Assign an existing Security Group to the Web servers:

* Resource Name: sgWeb

* Instances: Web Sewers

* Constraint Tag Key: sg

* Constraint Tag Value: atlasweb

Suggested Answer: A

To update the Atlas App cloud template to meet the specified requirements, you would perform the following steps in vRealize Automation:

Task 1: Edit the Cloud Template for Multi-tier Application

Access the vRealize Automation console and navigate to Design > Cloud Templates.

Open the existing cloud template named ''Atlas App''.

Modify the template to include:

2 Web Server Instances: Define two instances of the web server component.

1 Database Server Instance: Define a single instance of the database server component.

Build Order: Ensure the database server is set to be built before the web servers by adjusting the dependsOn property.

2 NSX Networks:

External Network (NAT): Create a network resource with the name external and configure it to use NAT.

Internal Network (Existing): Create a network resource with the name internal and link it to the existing nsx-atlas-existing network.

Restrict Networks: Apply constraints to ensure that only networks associated with the Atlas project are used.

Task 2: Add NSX Load Balancer

In the cloud template, add an NSX load balancer resource with the name lbWeb.

Configure the load balancer to distribute traffic to the web servers on port 443 using the HTTPS protocol.

Task 3: Assign Security Group to Web Servers

Define a security group resource with the name sgWeb.

Assign this security group to the web server instances.

Use constraint tags with the key sg and value atlasweb to ensure the security group is applied correctly.

Here is a simplified example of what the YAML configuration might look like:

resources:

dbServer:

type: Cloud.Machine

properties:

...

webServer1:

type: Cloud.Machine

properties:

dependsOn: dbServer

...

webServer2:

type: Cloud.Machine

properties:

dependsOn: dbServer

...

external:

type: Cloud.Network

properties:

networkType: nat

...

internal:

type: Cloud.Network

properties:

networkType: existing

constraints:

- tag: 'nsx-atlas-existing'

...

lbWeb:

type: Cloud.LoadBalancer

properties:

port: 443

protocol: HTTPS

...

sgWeb:

type: Cloud.SecurityGroup

properties:

instances: [webServer1, webServer2]

constraints:

- tag: 'sg:atlasweb'

...

Make sure to adjust the properties and configurations as needed to fit the specific details of your environment and the Atlas project. After updating the cloud template, validate the changes and ensure that the template meets all the requirements before saving.

I thought we could use any existing network, but it has to be nsx-atlas-existing?

Sounds straightforward, just need to follow the tier structure.

I know we need to assign the security group to the web servers, but I’m a bit hazy on the constraint tag key and value. Was it always "sg" and "atlasweb"?

I feel confident about adding the load balancer, but I keep mixing up the port numbers for HTTPS and HTTP. Is it definitely 443 for HTTPS?

I think we had a similar question about NSX networks in our last mock exam. The NAT feature for the external network sounds familiar, but I can't recall the exact settings we used.

I remember we practiced creating multi-tier applications, but I'm not sure about the order of resource creation. Did the database server really need to be built first?

This looks challenging, but I think if I take it step-by-step, I can get it done. The key will be making sure I fully understand all the networking and security requirements before I start implementing them.

Hmm, I'm a little confused about the networking requirements. I'll need to make sure I understand the different networks and how they should be configured. And the order of the web and database servers is important too.

This looks like a pretty complex task, but I think I can break it down step-by-step. First, I'll need to edit the existing cloud template to make it a multi-tier app with the required components. Then I'll add the load balancer and security group as specified.

Okay, I've got a plan. I'll start by creating the two web servers and the database server, making sure the DB server is built first. Then I'll set up the two networks, one with NAT and one using the existing NSX network. Finally, I'll add the load balancer and security group.

This seems pretty straightforward. Based on the information provided, I think the answer is to enable FC primary and secondary boot on the modules through the HPE OneView interface. That should get the job done.

Ah, I think I've got it. The mix of compensation components is one of the steps, so that can't be the "not considered" part. Gonna go with C on this one.
