BConfigure plug-in in the DMZ to send request to the cluster members.

Show Suggested Answer

Suggested Answer: C

The High Performance Extensible Logging (HPEL) facility writes to the log and trace repositories in a binary format. You can view, query and filter the repository using the LogViewer command.

logviewer.sh -monitor -includeLoggers Connection

-monitor [integer]Specifies that you want the logViewer to continuously monitor the repository and output new log record entries as they are created. You can provide an optional integer argument after this parameter to specify how often you want the LogViewer tool to query the repository for new records. By default the logViewer queries the repository for new records every 5 seconds. When used with other filtering options, only those new records that match the filter criteria are displayed.

Haha, I bet the system admin who has to set this up is just rolling their eyes. 'Oh great, another web service that needs to be accessed from outside the corporate network. Here we go again!'

I'm torn between options C and D. The ODR in the DMZ seems interesting, but the HTTP tunneling approach is probably more straightforward. Either way, I'm glad I don't have to be the one configuring this!

Configuring HTTP tunneling sounds like a solid solution. I can't imagine having to open up all those firewall ports - that would be a security nightmare!

Hmm, I think option D is the way to go. Tunneling the ORB requests through HTTP seems like a secure way to access the web service from outside the corporate domain.

Option D is a good choice. HTTP tunneling can help securely access the web service.

That's a good point, option C does provide an extra layer of security. It's important to consider all options before making a decision.

I disagree, I believe option C is the most secure option as it involves configuring on demand router (ODR) in the DMZ to send requests to the cluster members.

I think option A is the best choice because it involves opening firewall ports for both bootstrap and orb listener ports.
