Q51. After successfully adding a new ESXi 6.x host to vCenter Server, an administrator sees it as Not Responding in the vSphere Web Client interface a few minutes later. 

If the issue is caused by a network firewall blocking traffic, which port must be opened to correct this specific problem? 

A. 443 (TCP) 

B. 443 (UDP) 

C. 902 (TCP) 

D. 902 (UDP) 

Answer:


Q52. An administrator wants to upgrade to vCenter Server 6.x. 

The vCenter Server: 

. Is hosted on a virtual machine server running Microsoft Windows Server 2008 R2, with 8 vCPUs and 16GB RAM. 

. Will have an embedded Platform Services Controller. 

. Hosts a Large Environment with 1,000 ESXi hosts and 10,000 Virtual Machines. 

Why does the vCenter Server not meet the minimum requirements? 

A. Windows Server 2008 R2 is not a supported Operating System for vCenter Server. 

B. The virtual machine has insufficient resources for the environment size. 

C. The environment is too large to be managed by a single vCenter Server. 

D. The Platform Services Controller must be changed to an External deployment.

A. Administrator 

B. Network Administrator 

C. Datastore Consumer 

D. Read-Only 

Answer: B,C 


Q54. Refer to the Exhibit. 

An administrator recently created a Virtual SAN but no Storage Policies were defined. A few virtual machines were deployed to this cluster. The administrator analyzes the default Virtual SAN policy as shown in the Exhibit. 

Based on the exhibit, which two statements are true? (Choose two.) 

A. Losing one cluster node will not affect data availability. 

B. Losing one Hard Disk in a cluster node will not affect data availability. 

C. Creating a virtual machine Swap file will fail if it violates default storage policy. 

D. Creating a virtual machine will succeed even if it violates default storage policy. 

Answer: A,B 


Q55. Which file determines the location of the installation script during a scripted upgrade? 

A. boot.cfg 

B. ks.cfg 

C. script.cfg 

D. upgrade.cfg 

Answer:


Q56. Refer to the Exhibit. 

An administrator is troubleshooting intermittent poor performance of virtual machines in a vSphere 6.x cluster. Investigating esxtop data shows that the only statistic that stands out is %CSTP as depicted in Exhibit 1: 

The administrator proceeds to switch to the Power Management screen and observes the data depicted in Exhibit 2: 

Based on the information in the exhibits, which two configurations are probable causes of the poor performance? (Choose two.) 

A. The active power policy is set to Low Power. 

B. The host has active Sleep States configured in the BIOS. 

C. The active power policy is set to High Performance. 

D. The host has active Power States configured in the BIOS. 

Answer: A,B 


Q57. An administrator is configuring Storage I/O Control. After enabling, the administrator notices high device latency and poor storage performance. 

Which two actions would likely reduce latency and improve functionality? (Choose two.) 

A. Set the congestion threshold to 15ms 

B. Set the congestion threshold value to 5ms 

C. Ensure that each datastore has independent spindles 

D. Ensure that each datastore uses shared spindles 

Answer: A,C 


Q58. An administrator is configuring resource pools for a vSphere 6.x cluster. The cluster has these characteristics: 

Five ESXi 6.x hosts 

Six cores per host 

70 virtual machines with 1 vCPU each 

The administrator configures three resource pools and places the virtual machines into the pools, as follows: 

Production pool - High Share value with 40 virtual machines 

Infrastructure pool - Medium Share value with 20 virtual machines 

Development pool - Low Share value with 10 virtual machines 

Given this configuration, what is the expected performance for each group of virtual machines during contention? 

A. Virtual machines in the Production pool will perform two times as well as those in the Infrastructure pool. 

B. Virtual machines in the Infrastructure pool will perform four times as well as those in the Development pool. 

C. Virtual machines in all resource pools will perform equally. 

D. Virtual machines in the Development pool will perform two times as well as those in the Infrastructure pool. 

Answer:


Q59. An administrator notices that a Windows virtual machine is using 95% CPU in Task Manager. 

Which two actions should be taken to resolve this issue? (Choose two.) 

A. Increase the memory reservation of the virtual machine. 

B. Increase the CPU Shares on the resource pool where the virtual machine resides. 

C. Decrease the CPU reservation of the virtual machine. 

D. Increase the CPU limit on the resource pool where the virtual machine resides. 

Answer: B,D 


Q60. An administrator is troubleshooting a virtual machine performance issue using vRealize Operations. 

Which two badges would help to identify possible resource contention concerns? (Choose two.) 

A. Health > Workload 

B. Health > Faults 

C. Risk > Time Remaining 

D. Risk > Stress 

Answer: A,D
