Exam 2V0-21.23 topic 1 question 39 discussion

Actual exam question from VMware's 2V0-21.23
Question #: 39
Topic #: 1
[All 2V0-21.23 Questions]

An administrator successfully installs VMware ESXi onto the first host of a new vSphere cluster 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 esxi101.corp.local.”
The following information has been provided to complete the configuration:

Host FQDN: esxi101.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

ONS Domain: corp.local -
In addition, all host configurations must also meet the following requirements:
The management network must use only IPv4 network protocols.
The management network must be fault tolerant.
Which three high level tasks should the administrator complete, at a minimum, in order to successfully log into the vSphere Host Client using the FQDN for esxi101 and complete the configuration? (Choose three.)

  • A. Ensure a DNS A Record is created for the VMware ESXi host on the corporate DNS servers.
  • B. Update the VMware ESXi Management Network DNS configuration to use the corporate DNS servers for names resolution.
  • C. Update the VMware ESXi Management Network IPv4 configuration to use a static a IPv4 address.
  • D. Configure at least two network adapters for the VMware ESXi Management Network.
  • E. Set the value of the VMware ESXi Management Network VLAN ID to 10.
  • F. Disable IPv6 for the VMware ESXi Management Network.

The answer is correct based on what is the minimum requirement to log into the host client using the FQDN. B is not required just to log into the host client, you could set that later.

ACE is what I answered on test, passed with 428. Do not listen to the others, they have obviously never done this. You DO NOT need B to connect to any host inbound with by DNS name.

True, but why C, since DHCP is already turned off?

The informations in the question are only given to you, they are not already set on the Host. So I guess ACE is right.

I think michael24 is wrong, and this is the correct answer. "DHCP: No" means the host is already configured with a static IP address. And he glossed over the requirement for the management network needing to be fault tolerant.

ACE The question says as the initial configuration, later you'll do the all requiritments. A - You need the dns record to enter the configuration via gui C - The esxi has to have an ip address E - The management interafce must to have the vlan 10 The other options are only to do all requiritments, but the question is only for the initial

(A) - DNS A record must exist on the DNS servers to connect via FQDN B - Incorrect, the host is already pointed to the corporate DNS servers C - Incorrect, "DHCP - No" means the IP is already set to static (D) - This must be done to meet the requirement "The management network must be fault tolerant" E - Incorrect, the VLAN ID is already set to 10 (F) - This must be done to meet the requirement "The management network must only use IPv4 network protocols"

"C - Incorrect, "DHCP - No" means the IP is already set to static" This isn't what it means. It means DHCP is not enabled on the network, so the host is unable to get an IP address automatically and a static one must be set. There's no indication a static IP is already configured.

If we take all requirements, the correct answer could be ACDEF. But the question is to have the strict minimum to be able to connect to the Host Client via FQDN. So the answer is ACE. D and F are the final target required, but not the minimum for the connection to Host Client B is a best practice, but not mandatory depending on the needs on the infrastructure

Read carefully: Only the ISO have been installed, Management networks have NOT CONFIGURED YET. The info IP, VLAN etc have been provided to you. A - You need to make sure that the Network team created a DNS entry for you C - Setup the management network e.g. IP Mask Gateway DNS E - Setup the VLAN to 10 At a minimum as asked that's all that's needed

What a Horrible, ambiguously worded question!! A is clearly needed for connection via FQDN B is clearly not required to meet the requirements, though may be needed later C is required, but already set, so it does not need to be set again D is not required as a minimum to connect, but is required for redundant network connectivity and this is stated as a requirement, so... E as with C, this is required, but already set so does not have to be changed. F is not required A,C,E is the best option here.

ACE: question ask for 3 answers -> to reach the host usign FQDN you must have a record A on DNS and the host must have an ip address; since there isn't DHCP server you need to set it. Furthermore a VLAN TAG is mentioned which means the switch port used by NIC on th host is set in TRUNK mode, threfore you must ADD the VLAN TANG on the management network via DCUI.

wanna share this You can select either manual or automatic DNS configuration of the ESXi host. The default is automatic. For automatic DNS to work, your network environment must have a DHCP server and a DNS server. In network environments where automatic DNS is not available or not desirable, you can configure static DNS information, including a host name, a primary name server, a secondary name server, and DNS suffixes. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.esxi.install.doc/GUID-D69AB84A-84DA-4AD0-851B-3964CAB53E36.html I think configure DNS is mandatory

"The management network must be fault tolerant." is a requirement for the solution. However the question is what is the minimum to complete in order to successfully log into the vSphere Host Client using the FQDN for esxi101 and complete the configuration? The redundant management network can be completed after. Think of this requirement as muddying the water.

ACE is the correct answer. Question is which tasks should be completed at a minimum to be able to logon using the FQDN and complete the configuration. All other items can be configured afterwards, but ACE are required to be able to logon with FQDN

The question does not say that. It clearly refers to which steps you need to complete at a MINIMUM to log in to vSphere Host Client and THEN complete the rest of the config. ACE are the bare minimum to complete this task, then after you logged in, make it Fault Tolerant and disable IPv6 if you want.
