Which vSphere 6.x feature enables you to mitigate the effects of storage latency during peak load periods in a virtualized data center?

JJ have you passed this exam?

thanks JJ, so Q&A of this aiotestking (with same correction) is the really test?

No there are 75 questions in the test bank so you could possibly get 25 that are not listed on here.

B for sure

The actual answer to the question is not listed.
It is SIOC or Storage I/O Control.
Listen carefully to the Storage I/O Control section of the training video. http://mylearn.vmware.com/mgrreg/courses.cfm?ui=www_edu&a=one&id_subject=64758

It answers the question in the last 10 seconds of the slide.

As we cannot select this as an answer, the next best option is Network I/O Control

As icg referenced, Virtual SAN is not a vSphere feature but a separate paid offering and is not included with vSphere

Sphere Network I/O Control version 3 introduces a mechanism to reserve bandwidth for system traffic based on the capacity of the physical adapters on a host. It enables fine-grained resource control at the VM network adapter level similar to the model that you use for allocating CPU and memory resources..
Version 3 of the Network I/O Control feature offers improved network resource reservation and allocation across the entire switch.

anyone that passed the exam have any consideration to do on that question? Network I/O is really the correct answer ?

From http://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/whitepaper/iscsi_design_deploy-whitepaper.pdf
Definately lists: SIOC is a congestion-driven feature. When latency remains below a specific latency value, SIOC is dormant. It is triggered only when the latency value on the datastore rises above a predefined threshold.
I cant find anything that says iCSCI has features to mitigate peak load latency. I think this is a bullshit question in the exam.

VMware Certified Advanced Professional 6 (Desktop and Mobility Deployment) – The industry-recognized VCAP6-DTM Deploy certification validates that you know how to deploy and optimize VMware Horizon 6 (with View) environments. It proves that you have the understanding and abilities required to leverage best practices to provide a scalable and dependable Business Mobility platform for your company. Some of the subjects include: Configuring and managing Horizon View components, configuring cloud pod archituecture, configuring Group Policy settings related to Horizon View, Configuring and optimizing desktop images for Horizon View & Mirage, Configuring and managing App Volumes AppStacks, Configuring desktop pools, Configuring and deploying ThinApp packaged applications, Configuring VMWare Identity Manager, etc.Sebastian’s take on the VCAP6 exam: “In my opinion VCAP6 examination is way better experience in comparison with VCAP5, the newest examination appears to be exactly like VMware HOL. The user interface is simple, questions are sorted on the right side of the screen, and could be hidden to the side or restored when needed. My advise on the questions window: if you would like make it floating, you should know how to restore it back. I ended up moving it around because I forget how to recover it back. The 2 arrows that looked like control buttons on the top were used to dock the window to left or right. Fonts can be resized, which from my opinion was a lot better than scrolling up and down the question. The reaction speed of the whole interface was so way quicker in comparison with VCAP5.5, and there wasn’t any lagging time experienced when changing from window to window. Something to bear in mind: BACKSPACE key is not working! I do believe it is good since you don’t reload your examination window by accident, but, it can be bothersome sometimes when you type something wrongly and you need to select and press Del to remove. The Desktop and shortcuts were arranged quite nicely, and all needed programs like internet browser or Mirage console can be launched. You will find there’s excellent interface for Remote Desktop Manager where you can find all important RDP connection to servers or desktops without the need to type account information. The web browser had all the links in the Favorite Bar. At the time I am penning this, there is no extra Thirty minute extension for Non-Native English speaker at No-Native English country, which is a bummer. You’ll find 39 question to answer within the 3 hours time, and this can be actually really hard for non-native English speakers just like me. Several questions take time to finish, therefore it is best to by pass the questions that you cannot answer, and complete those you are able to. After the 39 questions, you can get back on the uncompleted questions if you happen to have time. DO not squander a lot of time on one single question! The examination blue print can be obtained on my website at Szumigalski.com. It is well organized and following it for the examination preparation will assist a lot. Obviously, the best is if you can have a lot of hands on experience! I’m truly very pleased with the examination experience, although I passed this time by small margin, however i really know what I missed for the examination, study from the blunders and practice harder to familiarise myself with the environment. This accreditation could open up your career prospects!”
