Question 31

An architect is designing a solution based on the following information:

✑ Each ESXi host has a single physical NIC with two 10 Gbps ports.

✑ There is a performance-based service-level agreement (SLA) that guarantees 15 Gbps bandwidth for production virtual machines at all times.

✑ There is no budget to purchase additional hardware.

✑ The hardware replacement SLA is based on a delivery agreement of two business days.

Which recommendation for the configuration of vSphere High Availability (HA) should the architect include in the design?

    Correct Answer: D

    Given the information, the architect must ensure a constant 15 Gbps bandwidth for production virtual machines, and since each ESXi host has only one physical NIC with two 10 Gbps ports, it's critical to handle any potential NIC failures proactively. Proactive HA with automated remediation will ensure that virtual machines are migrated to another host before a total NIC failure can impact the SLA. This avoids potential disruptions and aligns with the requirement of maintaining the 15 Gbps bandwidth without additional hardware. Therefore, the best configuration recommendation is to set Proactive HA with automated remediation and consider an OEM with NIC failure conditions.

Discussion
luckybmeOption: D

D. There is an SLA requirement of VMs needing 15 Gbps Network connectivity at all times. To honor the SLA, VMs need to be migrated to a different host if there is at least one nic failure. It's not necessarily true ( option A) that these two NICs are being used to connect to different networks for configuring multiple isolation addresses.

I also think D is right and A is wrong

Aolivera

D is good. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.avail.doc/GUID-3E3B18CC-8574-46FA-9170-CF549B8E55B8.html

i think is D

nxt_RTX5Option: B

I Think it is B: das.IgnoreRedundantNetWarning = true is necessary because of one physical NIC with two ports to prevent ongoing HA configuration messages you either set the parameter or VMware recommends to add a second vmnic to the service console or management network vSwitch configured with NIC teaming, and that you keep both as active adapters, or place one in standby. Proactive HA will take care of the rest

hamadakota

I agree with you

cloud29Option: D

I thinks its D

nemisis95Option: A

A. Configure vSphere HA Configure % based admission control Configure two isolation addresses Consider an OEM with NIC failure conditions in their Proactive HA plugin

IronMtnOption: D

Agree with luckybme and Alchot

AlchotOption: D

From a risk mitigation perspective, D sounds good. There is a single dual port NIC. A hardware issue affects a port then single point of failure triggers on the already single point of failure scenario(single NIC). High risk to meet the SLA Then the other reason is the 15 Gbps SLA. To meet this both NIC ports must be working otherwise SLA breach is present with 10 Gbps single port operating. Keywords VMs needing 15 Gbps Network connectivity Healthy host capacity 2x10 Gbps = 20 Gbps Degraded host capacity 1x10 Gbps = 10 Gbps

zhongzhong5011Option: B

A : Admission control -just for cpu and mem ; Isolation address -for a host is or not network isolated .so A is no function for require that : the vms must be migrate when bandwidth is not enogh! https://docs.vmware.com/en/VMware-vSphere/7.0/vsphere-esxi-vcenter-server-701-availability-guide.pdf

CloudRRAOption: A

I think a is good https://kb.vmware.com/s/article/1002117
