"All WSAs in the group can view file analysis results" is also a valid function of joining Cisco WSAs to an appliance group. When WSAs are joined to a group, they can share information and data, including file analysis results, which can help improve overall security efficacy. However, it's worth noting that the primary purpose of joining WSAs to an appliance group is to support improved redundancy, as I mentioned earlier. So, both options A and B are correct answers, but B is the more commonly cited reason for joining WSAs to an appliance group.

A is correct. On the link below read the title: (Public Cloud File Analysis Services Only) Configuring Appliance Groups. You need only this part. https://www.cisco.com/c/en/us/td/docs/security/wsa/wsa-15-2/user-guide-md/swa-userguide-15-2-md/m-network-security.html

The question ask about benefit of joining WSA together, that means we already have multiple WSA in place. Therefore Answer A should be correct.

Say you've got 1 WSA that can view file analysis results, What is the purpose off adding a 2nd WSA ? It would be absurd to answer ' so i can view file analysis results ' !!!! The answer has to be redundancy.

The purpose normal human being install something more than 1 in their network is to improved redundancy. Option A is very ridiculous answer. Its a plus point. But the primary purpose should be B. :-(

B - What is the purpose guys, are you joining multiple WSA appliances together to view file analysis or to get redundancy and high availability features.

If you search for "Appliance Group" in Cisco's manual, the only reference is under "Public Cloud File Analysis Services" - so A is the best answer.

I would take A: Your are joining with appliance not WSA or ESA for clustering ( failover capabilities)

I would go with A. "file analysis" You can view the File Analysis details on the Service Status page of the new web interface of your appliance. You must join all managed appliances to the same appliance group in order to allow all content security appliances in your organization to display detailed results in the cloud about files sent for analysis from any Cisco Email Security appliance or Cisco Web Security appliance in your organization https://www.cisco.com/c/en/us/td/docs/security/security_management/sma/sma14-0/b_sma_admin_guide_14_0/b_NGSMA_Admin_Guide_chapter_0111.html
