Exam MS-100 topic 4 question 49 discussion

This should be B - the #PTA counter in Performance Monitor. Troubleshooting in Azure AD will only help if there is an active issue, the question states that you just wish to check that all agents are handling authentication requests. Ref - https://docs.microsoft.com/en-us/azure/active-directory/hybrid/tshoot-connect-pass-through-authentication#performance-monitor-counters

A is right It is asked to verifiy to "whether all the Authentication Agents are used for authentication" so if the agent works fine and is seen with ACTIVE Status from the Azure portal then it can't be used for anything else : authentication. so the answer is A

Took some time to set up but it 100% B.

Confusing questions since both the performance-counters on each server as the "agents-page" in AzureAD-connect can be used to see what agents are "being used". Depends if the question and answers on the exam will be exactly like this. "On the troubleshoot page" should be something like "on the AAD-Connect blade". Under "Agents" you can see what agents are active or inactive cause of on issue. The "Troubleshoot" page one the AAD-Connect blade doesn't contain anything useful. For that reason i'd go for B.

Ensure that the Pass-through Authentication feature is still Enabled on your tenant and the status of Authentication Agents shows Active, and not Inactive. A - MS WAY

answer b PTA

IMHO Answer B not right Performance Monitor counters Another way to monitor Authentication Agents is to track specific Performance Monitor counters on each server where the Authentication Agent is installed. Use the following Global counters (# PTA authentications, #PTA failed authentications and #PTA successful authentications) and Error counters (# PTA authentication errors): Answer A Right Check status of the feature and Authentication Agents Ensure that the Pass-through Authentication feature is still Enabled on your tenant and the status of Authentication Agents shows Active, and not Inactive. You can check status by going to the Azure AD Connect blade on the Azure Active Directory admin center. Reference https://docs.microsoft.com/en-us/azure/active-directory/hybrid/tshoot-connect-pass-through-authentication

Answer A is the right answer: https://github.com/MicrosoftDocs/azure-docs/blob/master/articles/active-directory/hybrid/tshoot-connect-pass-through-authentication.md

I think, this question could be rephrased in a different way.

I am hoping they give credit to either answer as technically both are correct. A and B but I think B is more correct because it goes into the whole being able to see which host is not being used as much reality as load balancing is not exactly a thing and/or if one host experiences issues that the others do not. A bit out of the scope for the question tho

Agreed with B. You were asked to verify whether Authentication Agents are USED. Use #PTA counter https://docs.microsoft.com/en-us/azure/active-directory/hybrid/tshoot-connect-pass-through-authentication#performance-monitor-counters

Probably B is right. They probably look for this answer with this question: "Another way to monitor Authentication Agents is to track specific Performance Monitor counters on each server where the Authentication Agent is installed. Use the following Global counters (# PTA authentications, #PTA failed authentications and #PTA successful authentications) and Error counters (# PTA authentication errors)" Ref - https://docs.microsoft.com/en-us/azure/active-directory/hybrid/tshoot-connect-pass-through-authentication#performance-monitor-counters

B for sure!

Answer is definitely B ad d2an said. To monitor Authentication Agents is to track specific Performance Monitor counters on each server where the Authentication Agent is installed. Use the following Global counters (# PTA authentications, #PTA failed authentications and #PTA successful authentications) and Error counters (# PTA authentication errors):

Answer is wrong - (this answer is listed as correct on other websites too...) On Azure Active Directory -> Azure AD Connect -> Pass-through authentication you can view the number of agents, authentication agent IP and status (e.g. Active) This indicates that a PTA Agent is authenticated and connected to Azure Service. It does not mean that it is actually capable of authenticating users. The question asks to verify whether Authentication Agents are USED for authentication. That is done with #PTA authentications counter.
