Q111

What happens when an NSX logical switch is deleted?

  • A All connected VMs lose connectivity
  • B NSX routers will fail immediately
  • C Traffic resumes through existing VLANs
  • D The switch cannot be restored automatically
Explanation Deleting a logical switch removes network connectivity for associated VMs until they are connected to another switch or their configuration changes, unlike the implications of other options.
Q112

Which service within NSX handles Layer 2 networking?

  • A NSX Logical Switches
  • B NSX Edge
  • C NSX Distributed Firewall
  • D NSX Load Balancer
Explanation NSX Logical Switches handle Layer 2 networking, while others focus on security and load balancing.
Q113

A company needs to deploy a multi-tenant architecture using NSX. What should be used for tenant isolation?

  • A Network Segments
  • B Security Groups
  • C Distributed Routers
  • D Edge Services Gateway
Explanation Network Segments provide isolation for multi-tenant architectures, while other options serve different purposes.
Q114

You are configuring VPN on NSX. What happens when you enable IKEv2 instead of IKEv1?

  • A Only Phase 1 is affected
  • B Phase 1 and 2 are affected
  • C IKEv2 is incompatible with NSX
  • D False—no configuration change occurs
Explanation Switching to IKEv2 affects both Phase 1 and 2 setup as it uses different negotiation methods than IKEv1.
Q115

Which service in NSX manages distributed firewalls?

  • A NSX Manager
  • B NSX Edge
  • C NSX Controller
  • D NSX Intelligence
Explanation NSX Controller manages control plane functions, including the distributed firewall, while other options have different roles.
Q116

A company needs to ensure data center traffic remains isolated. What feature should they use?

  • A VRF Lite
  • B VLAN Segmentation
  • C NSX Segments
  • D Standard Switches
Explanation NSX Segments provide logical segmentation for isolated traffic, while other options do not offer complete isolation.
Q117

You are configuring service chaining in NSX-T. What happens when you configure the service insertion policy?

  • A All services are applied equally.
  • B Traffic is not inspected.
  • C Services are configured in sequence.
  • D Service chaining is disabled.
Explanation Service insertion policy applies services in the order defined by the policy, while other options misrepresent how service chaining works.
Q118

Which service is primarily used for load balancing in NSX?

  • A NSX Load Balancer
  • B NSX Edge Router
  • C NSX Distributed Firewall
  • D NSX VPN Service
Explanation NSX Load Balancer is designed for load balancing, while other options serve different functions.
Q119

A company needs to restrict traffic between VMs on the same host. What should be used?

  • A NSX Distributed Firewall
  • B NSX Edge Firewall
  • C VLAN Segmentation
  • D NSX Service Composer
Explanation NSX Distributed Firewall can enforce policies at VM level, effectively restricting traffic between VMs.
Q120

What happens when you incorrectly configure the NSX Controller cluster size?

  • A Increased throughput and reliability
  • B Impact on routing efficiency
  • C Reduced control plane stability
  • D Higher resource consumption only
Explanation An incorrectly sized controller cluster can lead to control plane instability, affecting overall network performance.
