Q21

What happens when an NSX segment's DHCP server is down?

  • A No VMs can connect
  • B VMs use static IP only
  • C VMs rely on previously assigned IPs
  • D NSX reverts to default settings
Explanation VMs will retain their previously assigned IPs, as DHCP leases are honored until expiration.
Q22

Which service in NSX allows for load balancing of applications?

  • A NSX Load Balancer
  • B NSX Edge Firewall
  • C NSX VPN Service
  • D NSX Distributed Switch
Explanation NSX Load Balancer provides application load balancing, while others serve different networking functions.
Q23

A company needs to segment its network for compliance but maintain communication between segments. What should you recommend?

  • A Use NSX Micro-segmentation
  • B Implement VLAN Isolation
  • C Use Physical Firewalls
  • D Deploy Simple Subnets
Explanation NSX Micro-segmentation allows for security policies while maintaining inter-segment communication, unlike the others.
Q24

You are configuring an NSX Edges firewall rule for source IP addresses. What happens when no matching rules are found?

  • A Traffic is allowed by default
  • B Default Deny policy applies
  • C Traffic is redirected to localhost
  • D Logging is disabled for unmatched traffic
Explanation In NSX, an unmatched rule results in a Default Deny policy, blocking all traffic.
Q25

Which service in NSX Advanced Load Balancer enables automated scaling based on demand?

  • A Auto-Scale
  • B Global Server Load Balancing
  • C Application Firewall
  • D Content Switching
Explanation Auto-Scale automatically adjusts resources based on load, while the others perform different functions in load balancing.
Q26

A company needs to restrict communication between two segments in their network. Which NSX feature should they utilize?

  • A Port Groups
  • B Firewall Rules
  • C Routing Policies
  • D Overlay Transport
Explanation Firewall Rules control traffic flows between segments, while the others do not provide this capability.
Q27

What happens when a VMware NSX Edge appliance runs out of disk space?

  • A It automatically deletes old logs
  • B It reboots to free up space
  • C New configurations cannot be applied
  • D VMs shut down to conserve resources
Explanation When disk space is insufficient, new configurations cannot be applied; the other options are incorrect as they do not directly relate to this issue.
Q28

Which service is used for distributed firewalling in NSX?

  • A NSX Distributed Firewall
  • B NSX Edge Services
  • C NSX Load Balancer
  • D NSX VPN Services
Explanation The NSX Distributed Firewall provides micro-segmentation, enhancing security, while others serve different functions.
Q29

A company needs to connect multiple remote sites to its NSX environment. What feature should they implement?

  • A NSX Distributed Routing
  • B NSX VPN Overlay
  • C NSX Service Composer
  • D NSX Load Balancer
Explanation NSX VPN Overlay is designed for secure connectivity between remote sites, while the other options serve different purposes.
Q30

What happens when an NSX Edge device runs out of resources?

  • A It reboots automatically.
  • B It halts all traffic.
  • C It spills over to another device.
  • D Performance may degrade.
Explanation Performance may degrade as it cannot handle additional load; the device does not reboot or halt but manages resources poorly.
