[All 301b Questions]

-- Exhibit --

Refer to the exhibit.

An LTM Specialist has created a virtual server to load balance traffic to a pool of HTTPS servers. The servers use client certificates for user authentication. The virtual server has clientssl, serverssl, and http profiles enabled. Clients are unable to connect to the application through the virtual server. Clients are able to connect to the application servers directly.

What is the root cause of the problem?

AThe application server does NOT support 2048-bit keys.

BThe clientssl profile is NOT set to require a client certificate.

CThe LTM device does NOT trust the issuing CA of the client certificate.

DThe application server does NOT see the client certificate due to SSL offload.

The app server not supporting 2048-bit keys is unlikely, right?

Wait, could SSL offload really cause that? Seems odd.

I think it might be the LTM not trusting the CA.

I agree, that's probably the issue here.

The clientssl profile needs to require a client certificate.

I don't recall the specifics, but I think the key size might not be the problem here. It seems more related to the clientssl profile settings.

I'm not entirely sure, but I feel like SSL offload could be causing the application server to miss the client certificate.

I think I saw a similar question where the trust relationship with the CA was the problem. Maybe the LTM device doesn't trust the issuing CA?

I remember something about client certificates needing to be required in the clientssl profile. Could that be the issue here?

I'm a bit confused by the SSL offload mention. Does that mean the LTM is terminating the SSL connection? If so, the application server may not be seeing the client certs.

Okay, let me think this through. The question mentions client certificates, so the clientssl profile must be set up correctly. I'll focus on checking that first.

This seems like a tricky one. I'll need to carefully review the details about the virtual server configuration and client authentication requirements.

Hmm, the key point here is that clients can connect directly to the application servers, but not through the virtual server. That suggests an issue with the LTM device's SSL/TLS settings.

Hmm, I wonder if the application servers are running on Windows. You know what they say, 'Windows and SSL, a match made in heaven.'

User 3: It could also be that the application server does not see the client certificate due to SSL offload.

Haha, I bet the LTM Specialist is kicking themselves for not double-checking the clientssl profile. Rookie mistake!

I agree with Veronika. Without requiring a client certificate, the clients won't be able to connect through the virtual server.

D is also a possibility. If the SSL offload on the LTM device is not configured correctly, the client certificate might not be forwarded to the application servers.

Option B seems like the most likely cause. If the clientssl profile isn't set to require a client certificate, the clients won't be able to authenticate with the application servers.

Yes, that makes sense. Without requiring a client certificate, the clients won't be able to connect to the application through the virtual server.

So, the root cause of the problem is likely that the clientssl profile is not set up correctly to authenticate the clients.
