Alfresco ACSCA Exam - Topic 1 Question 49 Discussion

If you are using an HTTP load-balancing mechanism in front of a clustered installation, 'sticky' routing must be enabled for the HTTP requests made by the Share tier to the repository tier (the /alfresco application). Select two ways to enable sticky routing?
A) Hard-wiring each /alfresco instance to its own /solr instance, and using the load balancer.
B) Hard-wiring each /share instance to its own /alfresco instance, bypassing the load balancer.
C) Ensuring that the load balancer must support 'sticky' sessions so that none of the clients always connects to the same server during the session.
D) Disabling alfrescoNtlm, passthru, or Kerberos authentication with SSO.
E) Enabling NTLM or Kerberos authentication with SSO, then Share will use cookie-based sessions and you can configure your load balancer to use sticky routing using the JSESSIONID cookie.

I disagree with D, disabling authentication seems risky.

I feel like option E is definitely related to SSO and cookie-based sessions, but I can't recall if that's the only way to achieve sticky routing.

I’m a bit confused about the difference between hard-wiring instances and using the load balancer. Wasn't there a question about that in our review?

I think option C sounds familiar because we discussed load balancers needing to support sticky sessions in our last practice exam.

I remember something about sticky sessions being important for maintaining user state, but I'm not sure which options specifically enable that.

Based on my understanding, Option E seems like the best solution. Enabling NTLM or Kerberos authentication with SSO will allow Share to use cookie-based sessions, which the load balancer can then use for sticky routing.

I think the key here is that the load balancer needs to support 'sticky' sessions, so that each client always connects to the same server during their session. Option C looks like the best choice for that.

Okay, let's think this through step-by-step. The question is asking about enabling 'sticky' routing for HTTP requests from the Share tier to the repository tier.

Option D looks promising - using analogies and anecdotes to guarantee student understanding. That could be a really effective strategy, but I'll need to make sure I understand the question fully before committing to an answer.

This is a good opportunity to demonstrate my troubleshooting skills. I'll need to consider factors like network segmentation, firewall rules, and potential misconfigurations.

I'm leaning towards C and E as well. Disabling authentication won't solve the problem, and hard-wiring instances doesn't sound like a great solution either.

Haha, option D is a good way to disable authentication, but that's not going to help with sticky routing! We need to keep authentication in place.

Option B doesn't make sense to me. Hard-wiring each Share instance to its own Alfresco instance would bypass the load balancer, which is the opposite of what we want.
