2V0-33.22 Sample Questions Answers

IPFIX (Internet Protocol Flow Information Export) is a standard for the format and export of network flow information for troubleshooting, auditing, or collecting analytics information. Port mirroring lets you replicate and redirect all of the traffic coming from a source. The mirrored traffic is sent encapsulated within a Generic Routing Encapsulation (GRE) tunnel to a collector so that all of the original packet information is preserved while traversing the network to a remote destination.

Use Traceflow to inspect the path of a packet. Traceflow traces the transport node-level path of a packet. The trace packet traverses the logical switch overlay, but is not visible to interfaces attached to the logical switch. In other words, no packet is actually delivered to the test packet’s intended recipients.

vRealize Log Insight is a log collection and analytics virtual appliance that enables administrators to collect, view, manage and analyze syslog data. Log Insight provides real-time monitoring of application logs, network traces, configuration files, messages and performance data.

The three types of gateways that can be found in VMware Cloud on AWS are Option A: Distributed Tier-1, Option B: Standard Tier-1, and Option D: Compute Tier-1.

Distributed Tier-1 gateways are used for secure access between on-premises networks and the VMware Cloud on AWS SDDC network. Standard Tier-1 gateways are used for secure access between the VMware Cloud on AWS SDDC network and the public internet. Compute Tier-1 gateways are used for secure access between the workloads running on the VMware Cloud on AWS SDDC and the public internet.

Gateway firewalls are used to protect east-west traffic, while distributed firewalls control the I/O path to and from a VM's virtual NIC. Furthermore, gateway firewalls and distributed firewalls cannot share the same sets of rules and policies.

The statement that most accurately describes the service features of VMware Cloud on Dell EMC is C. An SDDC includes a minimum of one rack with three hosts. You can add hosts to the rack, up to the maximum supported by the rack. An SDDC consists of a rack with a minimum of three hosts, which can then be expanded up to the maximum supported by the rack. VMware Site Recovery is not included as part of the initial service offering.

VMware Cloud on Dell EMC provides a service that enables customers to run their VMware-based workloads on Dell EMC's hardware, in a jointly-engineered and fully-supported environment. The service allows customers to deploy a fully-configured VMware SDDC on Dell EMC VxRail or VxRack SDDC systems, with the option to add more hosts to the rack as needed.

VMware Cloud on AWS is a managed service, and VMware handles the updates and patches to the infrastructure. When VMware notifies customers of upcoming maintenance or updates, it is usually for informational purposes, so the customer is aware. Unless there's a specific action item mentioned in the notification (which would be unusual), no action is required from the customer's end.

Upgrades for VMware Cloud on AWS SDDCs are deployed in a rollout across the service. When an upgrade rollout is available for your organization, you receive an email notification and a notification in the VMware Cloud Console. Typically, you receive this notification 30 to 60 days before upgrades begin for a rollout. After you receive the notification, you can submit a scheduling request for any of your SDDCs. So respond is required for initial schedule. If you receive the notification 7 days before start, this means you already responded to the proposed date and agree on it. https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-EE89B216-BE93-4A1A-9280-8F20E2A5266F.html https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-operations/GUID-7725CAAC-BBDB-4F80-991F-1D1ADDE12216.html#GUID-7725CAAC-BBDB-4F80-991F-1D1ADDE12216

Follow these recommendations to get the best performance when using snapshots:

· Use snapshots as a temporary measure only.The presence of snapshots can have a significant impact on guest application performance, especially in a VMFS environment, for I/O intensive workloads. The guest applications fully recover performance after snapshots are deleted.

· Keep the snapshot chain length short when possible, to minimize the guest application performance impact.Performance degradation is higher as the snapshot chain length increases.

· If you need to increase the size of a virtual disk that has snapshots associated with it, you must delete the snapshots first before you can increase the virtual disk's size.

https://docs.vmware.com/en/VMware-Tanzu-Kubernetes-Grid/index.html Tanzu Kubernetes Grid provides packaged services such as networking, authentication, ingress control, and logging that a production Kubernetes environment requires.

An extended network segment is required for a cloud administrator to create a virtual machine that requires layer 2 connectivity to an on-premises workload. Extended networks allow for the virtual machines to communicate directly with the on-premises workload while remaining isolated from the public cloud. This allows for the virtual machines to access the same services and workloads as the on-premises workloads while still remaining secure.

Based on the given guidelines, the cloud administrator should select the Elastic DRS Baseline policy [1]. This policy is designed to scale the cluster automatically when additional resources are required, while also ensuring that application performance is not affected during the scaling operation. The Elastic DRS Baseline policy also ensures that resources are allocated efficiently and optimally [1], to minimize cost while ensuring that performance requirements are met.

For more information on the Elastic DRS Baseline policy [1], see the VMware official documentation at https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws.sddc-management/GUID-FDD3A8AC-E42C-4B92-9C1D-8EB49D6C7129.html.

Tanzu Kubernetes clusters can be deployed in a VMware Cloud environment using the VMware Cloud Console. The VMware Cloud Console provides a user-friendly interface that allows users to quickly deploy and manage Tanzu Kubernetes clusters. The standard open-source kubectl can also be used to deploy Tanzu Kubernetes clusters. However, this requires a more in-depth knowledge of the kubectl command-line interface. Additionally, users can use the vSphere Plugin for kubectl to deploy and manage Tanzu Kubernetes clusters. This plugin provides a graphical user interface to manage the clusters, as well as additional features such as the ability to make cluster-level changes

The Cloud Services Portal communicates with the Workspace ONE Access Connector via port 443 (HTTPS). According to the VMware documentation [1], the Cloud Services Portal connects to the Access Connector on port 443 to authenticate users and authorize access to the cloud service. The Access Connector listens on port 443 and communicates with the Active Directory using LDAP over TLS (LDAPS) on port 636. Reference: https://docs.vmware.com/en/VMware-Workspace-ONE-Access/services/com.vmware.access.admin.configure.doc/GUID-F5C6FD9E-36DA-4B1F-A7E7-CF8F64A81D78.html

According to the VMware official documentation, in order to optimize scaling for full disaster recovery in a VMware Cloud on AWS environment, it is necessary to configure an Elastic DRS policy and select 'Optimize for Rapid scale-out' as the policy type. This option allows for a rapid increase in the number of hosts within the cluster, which is necessary for full disaster recovery. For more information, please refer to the VMware Cloud on AWS Disaster Recovery Guide, which can be found here: https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/VMware-Cloud-on-AWS-Disaster-Recovery-Guide.html.

The Workspace ONE Access connector is used to synchronize groups and users from the internal Active Directory to the VMware Cloud Services Console. Additionally, the administrator should configure a SAML 2.0 Identity Provider to enable single sign-on (SSO) capability and secure access to the VMware Cloud Services Console.

This role is designed to give administrators access to manage virtual machines, networks, and other settings within the folder. The CloudAdmin role will also give the junior administrators access to all global permissions that are associated with the Development folder.

"The CloudAdmin role is designed to give administrators access to manage a single folder. This role grants access to manage virtual machines, networks, and other settings within the folder. Additionally, this role grants access to all global permissions that are associated with the folder. For example, if the folder has global permissions that allow users to create or delete virtual machines, the CloudAdmin role will grant access to those permissions within the folder."

The CloudAdmin user can grant other users or groups read-only access to VMware Cloud on AWS vCenter management objects such as the Mgmt-ResourcePool, Management VMs folder, Discovered Virtual Machines folder, vmc-hostswitch, and vsanDatastore. Because this read-only access does not propagate to management objects, you cannot grant it as a Global Permission and instead must explicitly grant it for each management object. VMware Cloud on AWS runs a script once a day that updates any newly-created management objects (such as objects in a new cluster) so that the CloudAdmin user and CloudAdminGroup SSO group have the updated role applied. The script itself does not grant additional access to any user or group, so you'll need to wait until it completes before the CloudAdmin can use this workflow to grant read-only access to those objects.

CloudHealth by VMware is a cloud cost governance platform that provides budget management, cost reporting, and cost forecasting from a single platform. It provides comprehensive visibility and control to manage cloud costs in hybrid and multi-cloud environments.

A distributed switch is managed by vCenter Server for all ESXi hosts associated with the distributed switch. A standard switch is different from a distributed switch in that standard switches contain VMkernel ports, but the entire configuration is managed by each ESXi host. A distributed switch is managed by vCenter Server for all ESXi hosts associated with the distributed switch and can contain multiple VMkernel ports. Each ESXi host can have multiple distributed switches configured at any time.

To deploy an instance of Azure VMware Solutions, an administrator must take the following two steps:

• Create a support request with Microsoft Azure Support to create a host quota. This is required because Azure VMware Solution hosts are dedicated bare-metal servers that are not shared with other customers1. The host quota determines the number and size of hosts that can be provisioned in a subscription1. The host quota can be requested for an eligible Azure plan, such as Microsoft Enterprise Agreement or Cloud Solution Provider2.
• Deploy and configure Microsoft Azure ExpressRoute. This is required because Azure VMware Solution uses ExpressRoute to connect the private cloud to the Azure virtual network and the on-premises network3. ExpressRoute provides a secure, high-bandwidth, and low-latency connection that enables seamless workload migration and hybrid cloud scenarios3. The administrator must deploy and configure an ExpressRoute circuit, a virtual network gateway, and a virtual network3. References: 1: Deploy and configure Azure VMware Solution, 2: Plan the Azure VMware Solution deployment, 3: Tutorial: Deploy an Azure VMware Solution private cloud

The two VMware solutions that can meet the customer's requirement for a self-managed VDI solution are D. VMware Horizon and E. VMware Workspace ONE Access. VMware Horizon is a virtual desktop and application virtualization platform that enables customers to set up and deploy a virtual desktop infrastructure in any cloud environment. VMware Workspace ONE Access provides secure access to applications, data, and devices in any cloud environment.

Kubernetes is an open-source container orchestration system that provides automated deployment, scaling, and management of containers. It can be used to set up an automated restart policy for containers in the event of a failure, ensuring that containers are automatically restarted when they fail.

Private L2 VPN: To migrate running VMs between SDDCs in different geographical locations.

You use a private layer 2 (L2) VPN to extend an on-premises network to your cloud SDDC. This extended network is a single subnet with a single broadcast domain.

You can use L2 VPNs to migrate VMs to and from your cloud SDDC, for disaster recovery, or for dynamic access to cloud computing resources (often called cloud bursting).

VM migrations across an L2 VPN support VLAN tagging and GENEVE frame encapsulation when migrating between a cloud SDDC to another SDDC.

The L2 VPN tunnel extends layer 2 networks across geographic sites. VMs can move across sites (using vSphere vMotion) and keep the same IP addresses using an L2 VPN.

The problem could be that the new password is not synchronized with the password that is displayed for the Default vCenter user account. The administrator must make sure that the same password is used in both the vSphere Client and the VMware Cloud console in order for the user to access the account. Changing the password in one place does not automatically change it in the other, so this must be done manually.

When deploying VMware Cloud on Dell EMC or VMware Cloud on AWS Outposts, the Dell or AWS guys will bring a populated rack to the on-prem DC to extend the private cloud. They will bring technisians on-site to carry, install and configure the devices. AWS Outposts rack hardware specs: https://aws.amazon.com/outposts/rack/hardware-specs/?nc=sn &loc=4 https://docs.vmware.com/en/VMware-Cloud-on-Dell-EMC/services/vmc.dell.emc.datasheet/GUID-9252D1FC-FE9C-4317-8EEB-4C019A21CAA9.html

(Reference: https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vcloud.admin.doc/GUID-3568D3B3-ACFE-41F1-A966-5D4784F8A7A0.html )

To request access to the VMware Cloud on AWS service, the cloud administrator must log in to the VMware Cloud Console and fill out the New Subscription Request form. Once the form is filled out and submitted, the cloud administrator will receive an email with instructions on how to access the VMware Cloud on AWS service.

The cloud administrator will also need to have the Administrator role in the VMware Cloud on AWS service in order to gain access. The Administrator role allows the cloud administrator to access the VMware Cloud on AWS service, view the services available in the VMware Cloud on AWS console, and manage the resources in the SDDC.

Option C is the best design decision that meets the network connectivity requirements. Configuring a Direct Connect from headquarters to VMware Cloud on AWS with a private VIF will ensure high-throughput data transfer and eliminate the single point of failure. To ensure that all network traffic between on-premises company locations is sent over a private IP address space, a route-based IPsec VPN tunnel should be configured as a secondary method of connectivity from headquarters to VMware Cloud on AWS, taking care to enable the "Use VPN as Backup to Direct Connect" option. Finally, dual, redundant, route-based IPsec VPN connections should be configured from each regional office to VMware Cloud on AWS.

A route-based VPN creates an IPsec tunnel interface and routes traffic through it as dictated by the SDDC routing table. A route-based VPN provides resilient, secure access to multiple subnets. When you use a route-based VPN, new routes are added automatically when new networks are created. https://docs.vmware.com/en/VMware-Cloud-on-AWS/services/com.vmware.vmc-aws-networking-security/GUID-5AF45CE6-FA53-45C0-83E5-25F8E3A055E9.html

According to the VMware Cloud on AWS documentation, the minimum capacity of an i3.metal host is 8 vCPUs and 64 GB of memory. Therefore, to meet the demand of an additional 60 cores and 640 GB of memory, the administrator should add two i3.metal hosts to the cluster. For more information, please refer to the official VMware Cloud on AWS documentation at: https://docs.vmware.com/en/VMware-Cloud-on-AWS/index.html.

"The VMware HCX on-premises deployment requires five IP addresses: two for the WAN appliance, two for the vMotion feature, and one for the management network." 

In this scenario, the cloud administrator is utilizing the vMotion feature of VMware HCX to migrate several dozen workloads from an on-premises location to a VMware public cloud. They are also stretching three networks for the migration. When using vMotion, two IP addresses will be needed per vMotioned virtual machine: one for the source and one for the target. For the migration of several dozen workloads, this will require several dozens of IP addresses. Additionally, the administrator is also utilizing the capabilities of the WAN appliance to optimize migration traffic. In order to optimize the traffic, one IP address will be needed for the WAN appliance on the on-premises site, and another IP address will be needed for the WAN appliance on the public cloud side. Therefore, the total number of IP addresses that need to be reserved for the on-premises deployment of VMware HCX is the number of IP addresses required for the virtual machines plus one IP address for the WAN appliance on the on-premises site plus another IP address for the WAN appliance on the public cloud side, which totals to five IP addresses.
