VMware VCP6-DCV 2V0-621D Questions & Answers

• Question 51:

  Refer to the Exhibit.

  

  An administrator has configured a firewall rule as shown in the Exhibit. Which statement best describes the ESXi 6.x firewall rule?

  A. Connections from the ESXi host to all devices on the 192.168.1.0 network and 192.168.2.220 on port 22 are allowed.

  B. Connections coming from IP addresses from the 192.168.1.0 network and 192.168.2.220 on port 22 are allowed.

  C. TCP Connections coming from IP addresses from the 192.168.1.0 network and 192.168.2.220 on port 22 are not allowed.

  D. TCP Connections from the ESXi host to all devices on the 192.168.1.0 network and 192.168.2.220 on port 22 are not allowed.

  Correct Answer: B

  As stated clearly in the IP addresses box, connections coming from 192.168.1.0 and 192.168.2.220 on port 22 are allowed.

• Question 52:

  An administrator tries to capture network traffic for a virtual machine, but cannot see the expected traffic in the packet capture tool. Which step can resolve the problem?

  A. Migrate the virtual machine to a Distributed Virtual Switch.

  B. Enable Promiscuous Mode on the relevant port group.

  C. Modify the default value of MAC Address changes.

  D. Enable Forged Transmits on the virtual machine.

  Correct Answer: B

  Although it is not a good practice to enable promiscuous mode on a distributed virtual switch, you can enable it to solve the problem of traffic stats in packet capture tool.

• Question 53:

  Which two features are available for virtual machines configured with DirectPath I/O? (Choose two.)

  A. Fault Tolerance

  B. Suspend and Resume

  C. Virtual Symmetric Multi-Processing (vSMP)

  D. Virtual Non-Uniform Memory Access (vNUMA)

  Correct Answer: CD

  VMs configured with DirectPath I/O have vSMP and vNUMA.

• Question 54:

  Refer to the Exhibit.

  

  An administrator has configured a vSphere 6.x DRS cluster as shown in the Exhibit. Based on the exhibit, which statement is true?

  A. A virtual machine can be powered on in the Test Resource Pool with a 6 GB Memory Reservation.

  B. A virtual machine can be powered on in the Dev Resource Pool with a 8 GB Memory Reservation.

  C. A virtual machine from both the Test Resource Pool and the Dev Resource Pool can be powered on with a 4 GB Memory Reservation.

  D. No more virtual machines can be powered on due to insufficient resources.

  Correct Answer: A

  Using 6 GB reservation, a VM can be powered on in the test resource pool. IT has an expandable memory reservation that can help starta VM in the resource pool.

• Question 55:

  Refer to the Exhibit.

  

  The Prod-DB virtual machine has a VM Override as shown in the Exhibit.

  What step, it taken, would require all virtual machines in the cluster to migrate automatically?

  A. Deselect the virtual machine from VM Overrides.

  B. Add all virtual machines to the VM Overrides.

  C. Change Response for Host Isolation to Use Cluster Settings.

  D. Change the Automation level to Use Cluster Settings.

  Correct Answer: D

  After you create a DRS cluster, you can customize the automation level for individual virtual machines to override the cluster's default automation level.

  For example, you can select Manual for specific virtual machines in a cluster with full automation, or Partially Automated for specific virtual machines in a manual cluster.

  If a virtual machine is set to Disabled, vCenter Server does not migrate that virtual machine or provide migration recommendations for it. This is known as pinning the virtual machine to its registered host.

• Question 56:

  An administrator is using Auto Deploy to create several ESXi 6.x hosts that will be connected to a vSphere Distributed Switch. After the hosts are deployed, the administrator notices that LACP packets are not being sent between them. Which statement best describes why this issue is occurring?

  A. LACP is not enabled on the vCenter Server.

  B. The LACP support settings do not exist in the host profile.

  C. The LACP installation bundle is not included in the image profile.

  D. LACP has not been configured on the Auto Deploy server.

  Correct Answer: B

  Link Aggregation Control Protocol (LACP) on a vSphere distributed switch allows network devices to negotiate automatic bundling of links by sending LACP packets to a peer. However, there are some limitations when using LACP with a

  vSphere-distributed switch.

  LACP only works with IP Hash load balancing and Link Status Network failover detection.

  LACP is not compatible with iSCSI software multipathing. vSphere only supports one LACP group per distributed switch, and only one LACP group per host.

  LACP settings do not exist in host profiles.

  LACP between two nested ESXi hosts is not possible.

  LACP does not work with port mirroring.

• Question 57:

  Which two identification sources can a vSphere Auto Deploy rule use to identify target hosts? (Choose two.)

  A. Processor Serial Number

  B. Security Identifier

  C. SMBIOS information

  D. BIOS UUID

  Correct Answer: CD

  Rules can assign image profiles and host profiles to a set of hosts, or specify the location (folder or cluster) of a host on the target vCenter Server system. A rule can identify target hosts by boot MAC address, SMBIOS information, BIOS UUID, Vendor, Model, or fixed DHCP IP address. In most cases, rules apply to multiple hosts. You create rules by using Auto Deploy PowerCLI cmdlets. After you create a rule, you must add it to a rule set. Only two rule sets, the active rule set and the working rule set, are supported. A rule can belong to both sets, the default, or only to the working rule set. After you add a rule to a rule set, you can no longer change the rule. Instead, you copy the rule and replace either items or patterns. By default, Auto Deploy uses the name of the rule for the copy and hides the original rule.

• Question 58:

  Refer to the Exhibit.

  

  An administrator has created the DRS cluster shown in the Exhibit. Based on the exhibit, which statement is true?

  A. Under CPU contention, Prod-VM1 receives four times the CPU resources than Test- VM1.

  B. The Prod-VM1 will always have more CPU resources than all other virtual machines.

  C. The Test-VM2 will always have less CPU resources than all other virtual machines.

  D. Under CPU contention, Test-VM1 will receive 25% of the total CPU resources.

  Correct Answer: A

  Prod-VM1 will receive four times the CPU resources the Test-VM1 because the CPU contention is high compared to the test resource pool.

• Question 59:

  After configuring a Virtual SAN cluster, an administrator using the vSphere Web Client notices that the Virtual SAN datastore is smaller than expected. The cluster contains:

  Three ESXi hosts Each host has one 10GB SDD Each host has one 100GB HDD

  Why would the Virtual SAN datastore show as 100GB instead of 300GB?

  A. There is a network problem with the Virtual SAN vmkernel ports.

  B. The Virtual SAN VASA provider is disabled.

  C. vSphere High Availability is enabled on the Virtual SAN cluster.

  D. The Virtual SAN cluster must be managed using the vSphere Web Client.

  Correct Answer: A
