Master Cisco 300-810: Your Gateway to Collaboration Wizardry

Correct : D

This option is the correct action to resolve the issue of users receiving the error ''Single Sign On Failed.Invalid Status code in Resume'' when trying to log in through the SAML SSO. The error indicates that the SAML response from the internal IdP is invalid or expired, and that the Webex app cannot resume the SSO process. To fix this issue, the administrator must configure SSO in Control Hub ADFS, which is a Microsoft service that acts as an IdP and provides SAML authentication for Webex. By configuring SSO in Control Hub ADFS, the administrator can ensure that the SAML response is valid and matches the Webex app requirements. Reference:

Correct : B

This option is the correct MFA solution that can be integrated with Cisco Jabber via SAML and used independently of an IdP. Cisco DUO is a cloud-based MFA service that provides an additional layer of security for SAML SSO. Cisco DUO can be configured as a SAML IdP proxy that sits between Cisco Jabber and the actual IdP, or as a standalone SAML IdP that does not require another IdP. Cisco DUO supports various authentication methods, such as push notifications, phone calls, SMS messages, or hardware tokens. Reference:

Correct : A

This option is the correct way to find information about packet loss, jitter, and codecs in use in the Webex App for Windows during a call. The Settings menu allows users to access various options and preferences for the Webex App, including the Status option. The Status option shows the current network status and quality of service for the app. Users can press Diagnostics or use the keyboard shortcut Ctrl+Shift+Alt+S to open a detailed report of the call statistics, including packet loss, jitter, and codecs in use for audio and video.

Correct : C

I understand your reasoning, but I think option C is still the correct answer. The question is about Cisco Webex calling, which is a cloud-based service that provides voice and video calling features. Cisco Webex calling does not use UDP port 5062 for SIP signaling, but TCP port 8934. The Cisco Unified Border Element (UBE) is a local gateway that connects the PSTN to the Webex calling service. The UBE uses UDP port 5062 for SIP signaling only between itself and the PSTN, not between itself and the Webex calling service. Therefore, opening UDP port 5062 on the firewall will not help Alice to reach Charlie using Webex calling.

Correct : C

To resolve invalid certificate prompts in Cisco Jabber when using CA-signed certificates, you need to import the root certificate of the Certificate Authority (CA) into the 'Trusted Root Certification Authorities' store on the Windows client machine. This store holds certificates from trusted CAs, enabling the system to validate the certificate chain.
