• Question 22:

• Question 23:

  An administrator wants to deploy a vApp and dynamically assign IP addresses without a DHCP server on the network. Which action would you take to accomplish this task?

  A. Enable IP pools.
  B. Configure a local DHCP server in the vApp.
  C. Enable NAT on the vApp router.
  D. Configure the guest OS for workgroup and WINS.
  A. Enable IP pools.

  ---

  IP pools were first introduced with vSphere 4, but they're not necessarily used by everyone. IP pools are necessary if you want create or deploy a vApp. They provide a network identity to vApps. IP pool gives a network config to VMs that run in the vApp. So you'll also need to have an IP pool configured if you want to test vCloud Automation Center (VCAC) or Horizon Workspace.

  When you configure an IP Pool you specify a range of either IPv4 or IPv6 addresses, DNS and proxy settings, and select which vSwitch port groups that the pool will be available to. Usually you'll want to do a static IP for server VMs, but you might want to have a test VLAN for developments and you need DHCP there.

• Question 24:

  An administrator has a virtual machine that requires four times the compute resources than other virtual machines on the same ESXi 6.x host. How should the administrator configure the virtual machine settings, in order to be prepared for any resource contention?

  A. Set the shares of the priority virtual machine to High and the rest to Low.
  B. Set the shares of the priority virtual machine to High.
  C. Set the shares of the priority virtual machine to High and the rest to Normal.
  D. Set the shares of the priority virtual machine to Normal and the rest to Low.
  A. Set the shares of the priority virtual machine to High and the rest to Low.

  ---

  For the virtual machine that requires more resources, you can set the shares of the priority VM to high and set the rest to medium or low. Reference: http://www.globalknowledge.net/mea-shared-content/documents/645372/645389/WP_VM_Resource_Pools.pdf (page 3)

• Question 25:

  An administrator needs to deploy five virtual machines to a Virtual SAN-based datastore. Each virtual machine has a 50GB virtual disk and 16GB of memory. The remaining space on the datastore is 300GB. The administrator is unable to power on all five virtual machines concurrently.

  Which two statements will enable the administrator to power on all five virtual machines concurrently? (Choose two.)

  A. Create an 8GB memory limit for each virtual machine.
  B. Use per-virtual machine swap for the five virtual machines.
  C. Create an 8 GB memory reservation for each virtual machine.
  D. Use host-local swap for the five virtual machines.
  C. Create an 8 GB memory reservation for each virtual machine.
  D. Use host-local swap for the five virtual machines.

• Question 26:

  Which vSphere 6 Standard Edition feature will allow an organization to ensure that critical multi-threaded applications have the maximum possible uptime?

  A. Fault Tolerance
  B. High Availability
  C. Distributed Resource Scheduler
  D. App HA
  B. High Availability

  ---

  High availability is a permanent feature of vSphere 6 standard edition and it allows critical multi-threaded applications to get maximum possible uptime.

• Question 27:

  Which three are architecture components of vRealize Operations? (Choose three.)

  A. Identity Server
  B. Administrative Server
  C. Analytics Server
  D. Database Server
  E. Connection Broker
  B. Administrative Server
  C. Analytics Server
  D. Database Server

  ---

  Administrative, analytics and database server are active components of vRealize operations.

• Question 28:

  Which two SMTP Notification Event Details are specific to alarms triggered by events? (Choose two.)

  A. User Name
  B. Summary
  C. Old Status
  D. Target
  A. User Name
  B. Summary

  ---

  SMTP notification event details users username and summary to send email when the alarms are sounded off by events.

• Question 29:

  Which two statements are true about deploying and using vSphere Replication? (Choose two.)

  A. ESXi hosts managed by a single vCenter Server instance require a connection between the two vSphere Replication appliances.
  B. Sites managed by different vCenter Server instances require a connection between the two vSphere Replication appliances.
  C. Sites managed by different vCenter Server instances require the use of Site Recovery Manager and a connection between the two vSphere Replication appliances.
  D. ESXi hosts managed by a single vCenter Server instance require a single vSphere Replication appliance.
  B. Sites managed by different vCenter Server instances require a connection between the two vSphere Replication appliances.
  D. ESXi hosts managed by a single vCenter Server instance require a single vSphere Replication appliance.

  ---

  To use vSphere Replication between two sites managed by different vCenter Server instances, you must configure a connection between the two vSphere Replication appliances. You can complete this process on either site on which you have installed a vSphere Replication appliance. If you are using an untrusted certificate, certificate warnings might appear during the process. Alternatively, you can use vSphere Replication to replicate virtual machines between different ESXi hosts that the same vCenter Server manages. In this case, you deploy only one vSphere Replication appliance and you do not need to connect the primary and secondary sites.

  B. Define failover capacity by reserving a percentage of the cluster resources
  C. Use dedicated failover hosts
  D. Use Virtual Machine Monitoring
  A. Define failover capacity by static number of hosts
  C. Use dedicated failover hosts

  ---

  To avoid resource fragmentation, define failover capacity by static number of hosts and use dedicated failover hosts.
