Exam 300-820 topic 1 question 93 discussion

B is correct

The following proxy types are supported by Video Mesh: -Explicit Proxy (inspecting or non-inspecting) -None -Basic -Digest -NTLM -Transparent Proxy (non-inspecting) -Transparent Proxy (inspecting) https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cloudCollaboration/wbxt/videomesh/cmgt_b_webex-video-mesh-deployment-guide/cmgt_b_hybrid-media-deployment-guide_chapter_01.html

I know many have already said B is correct. I just wanted to post a more recent document. A is wrong because "Transparent" Explicit Proxy does not exist. See the full list under step 2. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cloudCollaboration/wbxt/videomesh/cmgt_b_webex-video-mesh-deployment-guide/cmgt_b_hybrid-media-deployment-guide_chapter_011.html#task_EA0A06C26910D9AFA85F888F201F0B44

B is correct. Book 300-820 page 422 Cisco officially supports the following proxy solutions that can integrate with your Webex Video Mesh Nodes: ■ Cisco Web Security Appliance (WSA) for transparent proxy ■ Squid for explicit proxy

In Cisco Naming for proxy types supported by VMN there is NO "Transparent Expicit Proxy" available. No "Reverse Proxy, and No "Distorting Proxy. Only one mentioned and supported "proxy type" on the link below is "transparent Insepected Proxy": https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cloudCollaboration/wbxt/videomesh/cmgt_b_webex-video-mesh-deployment-guide/cmgt_b_hybrid-media-deployment-guide_chapter_01.html Correct Answer is B (Transparent Proxy (inspecting))

see topic: "Requirements for Proxy Support for Webex Video Mesh" an following link: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cloudCollaboration/wbxt/videomesh/cmgt_b_webex-video-mesh-deployment-guide/cmgt_b_hybrid-media-deployment-guide_chapter_010.html

Correct (A): No Proxy—The default option before you integrate a proxy. No certificate update is required. Transparent Non-Inspecting Proxy—Video Mesh nodes are not configured to use a specific proxy server address and should not require any changes to work with a non-inspecting proxy. No certificate update is required. Transparent Inspecting Proxy—Video Mesh nodes are not configured to use a specific proxy server address. No http(s) configuration changes are necessary on Video Mesh; however, the Video Mesh nodes need a root certificate so that they trust the proxy. Inspecting proxies are typically used by IT to enforce policies regarding which websites can be visited and types of content that are not permitted. This type of proxy decrypts all your traffic (even https). Explicit Proxy—With explicit proxy, you tell the client (Video Mesh nodes) which proxy server to use, and this option supports several authentication types. After you choose this option, you must enter the following information:
