Exam AZ-305 topic 4 question 80 discussion

What's the point of memorizing this kind of sheit?

Answers are correct: Azure Virtual Machine: Use a high-performance Azure Virtual Machine such as the Dv3 or Ev3 series, which are optimized for workloads that require low latency and high throughput. SR-IOV: Enable SR-IOV on the Virtual Machine. SR-IOV allows for direct communication between the virtual NIC and the physical NIC, reducing latency and increasing throughput. Azure Premium SSD Disks: Use Azure Premium SSD Disks as they are optimized for performance-sensitive workloads and have a high IOPS and throughput limit.

CORRECT

To help you remember its a dumb sh1t question so DS VMs

Given answer is correct, Here is my take on this and no disrespect to anyone 1- If you got this question right within 60 seconds than i suggest you definitely need to get a life 2- MS asks such questions, i call them landmines!! means if you get it right (trigger the landmine) MS will know for sure you have been reading/accessing braindumbs; so i will happily answer this question wrong even though i was able to guess one part right!!

I will tattoo this info into my brain. Very important.

I just love questions like that.

Just memorise the answer. It's the one named after a Citroen. Don't have a way of memorising premium yet.

The exam is open book at last, so a search in the Exam for Virtual Machine DS gives the answer.

:-).. there is no point in asking such questions in design.

Answer is Correct: NC and NV does not support SR-IOV (Accelerated Networking). Per this note, enable it on this VMs types has no effect. https://learn.microsoft.com/en-us/azure/virtual-network/accelerated-networking-overview?tabs=redhat#supported-vm-instances So, only Ds vms type take advantage of SR-IOV. The, Premium SSD is enougth to support 15000 IOPs

From olabiba.ai: DS= Dedicated series NC=GPU-optimized NV=Virtualized GPU ....and I agree, Why we need to memorize this!!!!

Virtual machine series: The correct option is a. DS. Explanation: The DS series Azure Virtual Machines are designed for applications that require high storage performance and are ideal for SQL Server instances. The DSv3 and Dsv4-series, for instance, support Azure's premium SSDs and offer good I/O throughput, making them suitable for SQL Server workloads. NC and NV series are more oriented towards GPU-intensive and AI workloads, which are not the requirement in this case. SR-IOV is supported by DS series VMs. Disk Type: The correct option is b. Premium SSD. Explanation: To achieve 15,000 IOPS, you would need Premium SSDs. Standard SSDs offer lower performance in terms of IOPS and throughput, and while Ultra Disks could provide the necessary IOPS, they are more expensive and hence not the optimal choice for minimizing costs.

The answer seems correct: 1. DS Ideal for testing and development, small to medium databases, and low to medium traffic web servers. D-series, feature a more powerful CPU and optimal CPU-to-memory configuration, making them suitable for most production workloads. 2. Premium SSD Azure Premium SSDs deliver high-performance and low-latency disk support for virtual machines (VMs) with input/output (IO)-intensive workloads.(max IOPS 20,000) For any consultation see look this link is going to be helpful for every one : Link 1 = https://learn.microsoft.com/en-us/azure/virtual-machines/sizes Link 2 = https://learn.microsoft.com/en-us/azure/virtual-machines/dv2-dsv2-series Link 3 = https://learn.microsoft.com/en-us/azure/virtual-machines/sizes-general Link 3 = https://learn.microsoft.com/en-us/azure/virtual-machines/disks-types#disk-type-comparison

1. DS 2. Premium SSD https://learn.microsoft.com/en-us/azure/virtual-network/accelerated-networking-overview https://learn.microsoft.com/en-us/azure/virtual-machines/disks-types#disk-type-comparison Premium SSD - Max IOPS: 20,000

Premium SSD supports upto 20,000 IOPS Only DS supports SR-IOV/Accelerated Networking Although NC and NV sizes will show in the command below, they do not support Accelerated Networking. Enabling Accelerated Networking on NC or NV VMs will have no effect. https://learn.microsoft.com/en-us/azure/virtual-network/accelerated-networking-overview https://learn.microsoft.com/en-us/azure/virtual-network/accelerated-networking-overview
