Free VMware 3V0-42.23 Practice Test Questions 2026

Which of the following describes the role of the NSX Gateway Firewall as an intertenantfirewall within a VMware NSX solution?

A. It secures communication between on-premises physical servers and virtual machines (VMs) in the cloud.

B. It inspects and filters traffic between virtual machines (VMs) within the same tenant.

C. It isolates different tenants' virtual networks, preventing unauthorized communication between them.

D. It controls access to virtual resources based on user identity and authentication.

Which three VMware guidelines are recommended when designing VLANs and subnets for a single region and single availability zone?(Choose three.)

A. Use the RFC1918 IPv4 address space for these subnets and allocate one octet by region and another octet by function.

B. Use the RFC2460 IPv6 address space for these subnets and allocate one set by region and another set by function.

C. Use only /16 subnets to reduce confusion and mistakes when handling IPv4 subnetting.

D. Use only /24 subnets to reduce confusion and mistakes when handling IPv4 subnetting.

E. Use the IP address of the floating interface for Virtual Router Redundancy Protocol (VRRP) or Hot Standby Routing Protocol (HSRP) as the gateway.

A Solutions Architect is helping an organization with the multi-location design of an NSX solution.
This information was gathered during a design workshop:

No Jumbo Frames allowed on the WAN
Simple DR solution with no fabric nor vCenter requirements
GDPR requirements (Management Plane distributed in each location)

What should the architect recommend be configured in the NSX environment?

A. NSX Federation

B. NSX Multisite

C. Tier-0 Gateway Active/Active

D. IPSec VPN between the sites

Which of the following would be an example of an assumption that a solutions architect needs to consider in the design of an NSX solution?

A. The customer thinks that NSX will be able to integrate with their existing infrastructure.

B. The customer requires support for virtualized workloads across multiple hypervisors.

C. The customer wants to be able to scale the NSX solution as their business grows.

D. The customer has limited resources available for the implementation, such as personnel or hardware.

A company is planning to use NSX to provide network services for a highly distributed application that spans multiple data centers and cloud environments. A Solutions Architect is responsible for designing the network services to ensure that the application is highly available and performs well.

Which of the following NSX features should the Solutions Architect use to achieve this goal?

A. Network Address Translation (NAT)

B. Virtual Private Networks (VPNs)

C. Distributed Firewall

D. Advanced Load Balancer

Which combination of stateful services are available in an NSX Gateway?

A. NAT, DHCP, Load Balancer

B. Load Balancer, Firewall, Reflexive NAT

C. NAT, DNS, Firewall

D. TLS Inspection, DHCP, DNS

A Solutions Architect is designing an NSX solution for a customer who needs to extend their on-premises VLANs to a public cloud environment. The customer wants to use L2 bridging to extend the VLANs across the environments.

Which of the following design considerations should the Solutions Architect keep in mind when using L2 bridging solutions in NSX for this use case?

A. L2 bridging requires the use of Geneve encapsulation for traffic to traverse the public internet.

B. L2 bridging can cause delays in traffic and should only be used for low-latency applications.

C. L2 bridging should only be used when the on-premises and cloud environments are in the same geographical location.

D. L2 bridging requires the same IP subnet to be used in both the on-premises and cloud environments.

A global logistics company is planning to expand its operations to multiple locations across continents. Their existing on-premises network is unable to scale to meet the demands of the growing number of sites and the increasing volume of East-West traffic within their data center. The company has chosen VMware NSX as their preferred network virtualization platform, aiming to simplify network management and improve intra-data center routing.

Which of the following would be part of the optimal recommended design?

A. Deploy NSX and use Centralized Service Ports to handle East-West routing within the data center.

B. Deploy NSX with Aria Operations for Networks to handle North-South routing within the data center.

C. Deploy NSX with Tier-1 Gateways to handle East-West routing within the data center.

D. Deploy NSX with Tier-0 Gateways to handle North-South routing within the data center.
