Question 110

Which two actions should an administrator take to ensure a VM has the highest networking bandwidth? (Choose two.)

    Correct Answer: C, D

    To ensure a VM has the highest networking bandwidth, an administrator should configure resource pools and configure shares, reservations, and limits. Configuring resource pools allows for the allocation of bandwidth reservations for individual virtual machine traffic, ensuring that a specific VM receives a guaranteed portion of the network resources. Additionally, setting up shares, reservations, and limits on the network adapters of the VM ensures that network I/O control can allocate the necessary bandwidth based on these settings, providing prioritized and guaranteed network resources to the VM.

According to doc below, the correct answers are C and D: You can also use network resource pools where you can assign a bandwidth quota from the aggregated reservation for the virtual machine traffic and then allocate bandwidth from the pool to individual virtual machines. Network I/O Control version 3 allocates bandwidth to individual virtual machines based on configured shares, reservation, and limit for the network adapters in the VM hardware settings. https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.networking.doc/GUID-29A96AB2-AEBF-420E-BDD6-48921CD687FF.html

I agree with C and D. The question is VM-specific... how to ensure that a particular VM gets more bandwidth than others. C and D are the only two answers that can allow an Admin to give more bandwidth to a specific VM

Less administrative effort too with D over B Going with C & D

Correct answers are C & D. They are specific to the VM level.

I would say C&D - tricky question.

C & D is the right answer. https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-8E957535-7969-4E12-BD11-DF746D6D5379.html

JachpOptions: BD

B and D are correct answers D is correct and C may be correct but... why not C?, because according with the following link: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-8E957535-7969-4E12-BD11-DF746D6D5379.html Configuring resources pools is correct but talks about VIRTUAL MACHIN SYSTEM TRAFFIC connected to a distributed switches, and the questions says specific: TAKE TO ENSURE A VM HAS, it's singular, NOT plural, about singular "A VM HAS" then defining Bandwidth Requirements for a Virtual Machine talks about "bandwidth to a virtual machine according to shares, reservation, and limits " defined for A (1) virtual machine on his Network Adapter.

the problem is about the question itself -and the answers are provide us to select as the right once: Resource Pools created under DRS Clusters the VMs can be configured with Shares/Reservations/Limits (Memory/CPU Usage). Network Resource Pools created on the Distributed Switch level! but before creating Network Resource Pool we must first configured the System Traffic Setting with existing Traffic types with the 'Shares/Share Values/ Reservation/Limits and just then create the Network Resource Pool and associated with vDS Port Group . so what Resource Pool? what Traffic Shaping ? on the vSwitch configuration or on the vDS Configurations? Traffic Shaping or System Traffic Settings? Network Resource Pool or Cluster Resource Pool? LACP is an Option but..Resource Pool is consider an option? what about Traffic Shaping ?

DarkBlackOptions: BD

I think A! = traffic shaping is limit option B = if in OS uses bonding C != Only CPU and Memory D = https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vsphere.networking.doc/GUID-C3313EF6-AF3E-42A9-A251-02839BD11871.html E != QoS is limit option.

Sevon

Only CPU and Memory? No, it's called a Network Resource Pool and it exists. Network IO Control is built on this.
