Q171

What happens when an NSX distributed firewall rule is applied to a desired VM?

  • A Traffic is allowed or denied on the VM
  • B All traffic to the VM is blocked
  • C The VM gets isolated in the cloud
  • D The VM loses its network connectivity
Explanation Firewall rules dictate permission on the VM, rather than blocking all traffic or isolating it.
Q172

Which service identifies virtual network traffic flows?

  • A NSX Distributed Firewall
  • B NSX Load Balancer
  • C NSX Edge Services Gateway
  • D NSX Intelligence
Explanation The NSX Distributed Firewall inspects and filters traffic flows between VMs, while the others serve different functions.
Q173

A company needs to ensure maximum uptime for its NSX-T environment. Which design aspect should be prioritized?

  • A Network segmentation
  • B Load balancer redundancy
  • C Single point of failure
  • D Firewall rules optimization
Explanation Prioritizing load balancer redundancy mitigates points of failure, unlike options A, C, or D, which do not inherently address uptime.
Q174

What happens when a VM is moved to a different host in an NSX environment?

  • A It loses its networking configuration
  • B It retains its IP address
  • C It requires reconfiguration
  • D It cannot communicate until powered off
Explanation The VM retains its IP address due to NSX's virtual networking capabilities, while the other options present incorrect outcomes regarding VM movement.
Q175

Which service is primarily used for micro-segmentation in NSX?

  • A NSX Distributed Firewall
  • B NSX Load Balancer
  • C NSX Edge Services Gateway
  • D NSX VPN Services
Explanation NSX Distributed Firewall provides the micro-segmentation capability, whereas the others serve different networking functions.
Q176

You are configuring NSX-T Data Center, and need to ensure packets can be selectively intercepted. What should you configure?

  • A Service Insertion
  • B Logical Router
  • C Load Balancer
  • D Edge Cluster
Explanation Service Insertion allows interception of packets for third-party services, while the others focus on different functionalities.
Q177

What happens when an NSX segment is deleted while being used by active VMs?

  • A VMs automatically migrate to another segment
  • B VM traffic is interrupted
  • C Deletion fails with an error
  • D VMs retain IP configuration
Explanation Deleting an NSX segment interrupts traffic for active VMs, while the other options are not true in this scenario.
Q178

Which service provides network visibility in NSX?

  • A NSX Intelligence
  • B NSX Load Balancer
  • C NSX Edge
  • D NSX VPN
Explanation NSX Intelligence delivers network insights, while others focus on specific functions.
Q179

You are configuring a micro-segmentation strategy; what is crucial?

  • A Overlay networking
  • B Single IP addressing
  • C Static routing
  • D TLS encryption
Explanation Overlay networking enhances micro-segmentation flexibility, unlike options B, C, and D.
Q180

What happens when an NSX Router fails?

  • A Traffic reroutes instantly
  • B No impact on network
  • C Services crash immediately
  • D Traffic loss may occur
Explanation Traffic loss might occur until failover happens; options A and C are misleading.
