Discuss F5 Networks 301b Exam Topic 2 Question 93

An LTM Specialist has been asked to configure a virtual server to distribute connections between a pool of two application servers with addresses 172.16.20.1 and 172.16.20.2. The application servers are listening on TCP ports 80 and 443. The application administrators have asked that clients be directed to the same node for both HTTP and HTTPS requests within the same session.

Virtual servers vs_http and vs_https have been created, listening on 1.2.3.100:80 and 1.2.3.100:443, respectively.

Which configuration option will result in the desired behavior?

ACreate pool app_pool with members 172.16.20.1:any and 172.16.20.2:any
Assign app_pool as the default pool for both vs_http and vs_https
Disable port translation for vs_http and vs_https

BCreate pool http_pool with members 172.16.20.1:80 and 172.16.20.2:80
Assign pool http_pool as the default pool for both vs_https and vs_https
Disable port translation for vs_https
Create an SSL persistence profile with 'match across virtual servers' enabled
Assign the persistence profile to vs_http.

CCreate pool http_pool with members 172.16.20.1:80 and 172.16.20.2:80
Create pool https_pool with members 172.16.20.1:443 and 172.16.20.2:443
Assign http_pool as the default pool for vs_http
Assign https_pool as the default pool for vs_https
Create a source address persistence profile with 'match across services' enabled
Assign the persistence profile to vs_http and vs_https

DCreate pool http_pool with members 172.16.20.1:80 and 172.16.20.2:80
Create pool https_pool with members 172.16.20.1:443 and 172.16.20.2:443
Assign http_pool as the default pool for vs_http
Assign https_pool as the default pool for vs_https
Create an SSL persistence profile with 'match across virtual servers' enabled
Assign the persistence profile to vs_http

B sounds interesting, but does 'match across virtual servers' really work?

Marleen 11 months ago

I like A, but not sure about disabling port translation.

Vincent 11 months ago

Wait, why do we need two separate pools for HTTP and HTTPS?

Laquita 12 months ago

I disagree, I think D is more straightforward.

Marvel 12 months ago

Option C seems like the best choice for session persistence.

Amie 12 months ago

I'm leaning towards option A since it simplifies the configuration by using a single pool, but I'm not entirely confident about the port translation part.

Naomi 1 year ago

I practiced a similar question where we had to set up pools for different protocols, but I can't recall if we needed to create separate pools for HTTP and HTTPS like in option D.

Gilbert 1 year ago

I think option C sounds familiar because it mentions "match across services," which seems like it could help with directing clients correctly.

Reena 1 year ago

I remember something about persistence profiles being crucial for maintaining session consistency, but I'm not sure which one to use here.

Jani 1 year ago

I'm feeling pretty confident about this one. Option C looks like the best solution to me - it covers all the requirements and uses the appropriate persistence settings.

Lavonne 1 year ago

Okay, I think I've got a good handle on this. The key is to create separate pools for the HTTP and HTTPS traffic, and then use a persistence profile to keep clients on the same node for the duration of their session.

Kimberlie 1 year ago

Hmm, I'm a bit confused about the "match across virtual servers" part. Does that mean I need to apply the persistence profile to both virtual servers, or just one of them?

Geoffrey 1 year ago

This looks like a pretty straightforward configuration task, but I want to make sure I understand the requirements correctly before I start.

Gilberto 1 year ago

Hmm, I'm a bit unsure about this one. I'll need to review my notes on the VMware View architecture to figure out which component is the least available.

Alpha 1 year ago

This is a tricky one. I'm leaning towards the bottom-up approach, since the business analyst will likely get the most detailed and accurate information from the people actually performing the process. But I could see an argument for a top-down view as well. Guess I'll have to weigh the pros and cons.

Ah, the joys of load balancing. I bet the application admins are just sitting back, sipping their coffee, and enjoying the show.

Jani 1 year ago

Option D is looking good, but that SSL persistence profile just for the HTTP virtual server seems a bit odd. Why not apply it to both?

Ha! Option A is a classic case of 'set it and forget it'. Disable port translation for both HTTP and HTTPS? That's just asking for trouble down the line.

Hmm, I'm not sure about option B. Disabling port translation for HTTPS seems risky, and I'm not convinced the SSL persistence profile will work the way they want across both virtual servers.

Georgeanna 2 years ago

Option C looks like the way to go. Separate pools for HTTP and HTTPS, and a persistence profile that matches across services to keep the client on the same node. Simple and straightforward.

Rickie 2 years ago

I'm not sure, but option D also looks like it could work.

Roxanne 2 years ago

I agree with Isadora, option C seems to be the best choice.

Isadora 2 years ago

I think option C is the correct one.
