   A company is deploying a new application in their SDDC. The application has two tiers: a web server and a database server. The security policy requires that the database server cannot be accessed from any other VM except the web server. The administrator has vSphere and NSX deployed. What is the MOST efficient way to enforce this policy?

   • AUse vSphere's built-in firewall to restrict traffic to the database VM.
   • BConfigure the database VM's operating system firewall to only accept connections from the web server's IP address.
   • CPlace the web and database VMs on different VLANs and configure ACLs on the physical switch.
   • DCreate a distributed firewall rule in NSX that allows traffic from the web server VM to the database server VM on the database port, and denies all other traffic to the database server VM.

   A company is planning to deploy a new application that has unpredictable and spiky compute demands. They want to avoid over-provisioning physical hardware. They have decided to use an SDDC approach. What is the PRIMARY benefit of using vSphere in this scenario?

   • AIt allows the company to pool compute resources and dynamically allocate them to VMs as demand changes.
   • BIt automatically scales the application by adding more VMs based on CPU usage.
   • CIt eliminates the need for physical servers by running applications in containers.
   • DIt provides a self-service portal for developers to provision VMs on demand.

   A vSphere administrator is tasked with ensuring that a critical VM always has enough CPU and memory resources, even during periods of high demand on other VMs in the cluster. The company has adopted the SDDC model. Which vSphere feature should the administrator use to guarantee these resources for the critical VM?

   • AResource Pools
   • BDistributed Resource Scheduler (DRS)
   • CVM Reservations
   • DStorage I/O Control (SIOC)

   A company is planning to deploy a new application in their SDDC. The application has a web tier and a database tier. The web tier needs to be able to scale out to handle increased load. The database tier needs high availability. The administrator has vSphere deployed. What is the PRIMARY role of vSphere in enabling the scaling of the web tier?

   • AIt allows the administrator to quickly provision new VMs from a template to add capacity to the web tier.
   • BIt provides a load balancer to distribute traffic across the web tier VMs.
   • CIt ensures the database tier has high availability by restarting it on another host if it fails.
   • DIt automatically scales the web tier by adding more VMs when CPU usage exceeds a threshold.

   An organization is deploying a new application that requires low-latency, high-throughput storage. They plan to use vSAN as their primary datastore. The vSphere administrator needs to ensure that the VMs running this application can take full advantage of the vSAN performance capabilities. What is the MOST important integration point between vSphere and vSAN that the administrator must configure correctly?

   • ADistributed Resource Scheduler (DRS) to balance the VMs across hosts.
   • BvSphere High Availability (HA) to ensure the VMs restart if a host fails.
   • CNetwork I/O Control (NIOC) to prioritize vSAN traffic over other network traffic.
   • DStorage Policy Based Management (SPBM) to define performance and availability requirements.
