Refer to the exhibit. An engineer is deploying mobile and remote access in an environment that already had functioning Business to Business calling. Mobile and remote access SIP registrations are failing. To troubleshoot, SIP logs were collected. How is this issue resolved?
Which option mandates that calls fall back to unencrypted media if encryption cannot be established?
A Webex engineer is configuring SSO in Control Hub with Active Directory Federation Services. The engineer wants to authenticate users for all the applications that they are given rights to. The engineer also wants to eliminate further prompts when users switch applications during a particular session. Which action tells ADFS the fields to map to Webex to identify a user?
A Webex administrator is configuring the Webex Control Hub to enable enterprise users to sign into Webex securely by authenticating to the IdP of the organization. To conform to the SAML specification, to what can the NameID format be set?
Which 16-digit number is unique to a serial number and is used to enable the system?
Refer to the exhibit. What are “Type” field values for this Expressway servers zone configuration?
Refer to the exhibit. When a user tries to sign in to the Cisco Jabber client through Mobile and Remote Access, they receive this error message: “Cannot communicate with the server.” The external DNS server is configured with the SRV records listed in the exhibit.
What is the cause of the issue?
Which two scenarios need a proper DNS configuration on Expressway servers? (Choose two.)
Refer to the exhibit.
When a Jabber user attempts to connect from outside of the organization, the user enters the login information as "user@example.com" and receives the error "Cannot find your services Automatically". The engineer tries to resolve SRV records used by Jabber.
