An administrator is responsible for the management of a VMware vCenter instance that is currently experience performance issues. The administrator quickly identifies that the CPU and memory utilization of vCenter is consistently over 90%. Upon further analysis, it seems that the vpxd process is contributing significantly to the performance issue. A combination of which four steps should the administrator take to resolve the performance issues and ensure that a similar issue can be rectified without required downtime to vCenter moving forward? (Choose four.)
Answer(s): A,C,D,E

administrator successfully installs VMware ESXi onto the first host of a new vSphere duster but makes no additional configuration changes. When attempting to log into the vSphere Host Client using the Fully Qualified Domain Name (FQDN) of the host, the administrator receives the following error message:`'server Not Found we can't connect to the server at esxit101.corp.local.''- Host FQDN: esxi 101. Corp. local- Management VLAN ID: 10- DHCP: No- Management IP Address: 172.16.10.101/24- Management IP Gateway: 172.16.10.1- Corporate DNS Servers: 172.16.10.5, 172.16.10.6- DNS Domain: corp.localWhich three high level tasks should the administrator complete, at a minimum, in order to successfully log into the vSphsrs Host Client using the FQDN for the exxi101 and complete the configuration (Choose three.)
Answer(s): A,B
To successfully log into the vSphere Host Client using the FQDN for the ESXi host, the administrator needs to ensure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers, which maps its FQDN to its IP address; and update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for name resolution, which allows resolving its FQDN.

When configuring vCenter High Availability (HA), which two statements are true regarding the active, passive, and witness nodes? (Choose two.)
Answer(s): A,D
When configuring vCenter High Availability (HA), two of the requirements for the active, passive, and witness nodes are that network latency must be less than 10 milliseconds, which ensures reliable communication between them; and they must have a minimum of a 1 Gbps network adapter, which provides sufficient bandwidth for data replication.

An administrator is deploying a new all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA).What is the minimum supported network throughput in Gb/s for each host?
Answer(s): B
The minimum supported network throughput in Gb/s for each host in an all flash vSAN cluster based on the vSAN Original Storage Architecture (OSA) is 10.vSAN Express Storage Architecture (ESA) are only supported with 25Gbps and higher connection speeds. ESA ReadyNodes configured for vSAN ESA will be configured with 25/50/100Gbps NICs. vSAN OSA all-flash configurations are only supported with a 10Gb or higher connections. One reason for this is that the improved performance with an all-flash configuration may consume more network bandwidth between the hosts to gain higher throughput.

An administrator enables Secure Boot on an ESXi host. On booting the ESXi host, the following error message appears:Fatal error: 39 (Secure Boot Failed)
Answer(s): A
The fatal error "Secure Boot Failed" may indicate that either the kernel or a package (VIB or driver) has been tampered with, which violates the Secure Boot integrity check.
