Which two licenses are required for the Expressway B2B feature to work? (Choose two)

A remote branch office reports that Webex Board endpoints experience audio dropouts during active meetings, especially when file transfers occur simultaneously. WAN link utilization shows
95% usage during peak hours. Which two troubleshooting actions should be taken first? (Choose two.)

Refer to the exhibit. Mobile and remote access is being added to an existing B2B deployment and is failing.

When the administrator looks at the alarms on the Expressway-C, the snippets are shown. Which configuration action should the administrator take to fix this issue?

Refer to the exhibit. Mobile Cisco Jabber cannot register with on-premises Cisco Unified Communications Manager using Mobile and Remote Access. Some logs were captured on Expressway Edge.

Which action corrects this problem?

Where can the administrator manage a Webex tenant?

An enterprise is deploying Webex across multiple departments with strict security and compliance requirements. An engineer must implement:
- role-based access control for administrators
- end-to-end encryption for meetings
- device-level security enforcement
- integration with third-party compliance tools for legal hold and DLP
Which must be taken to meet the requirements?

Cisco media traversal technology has enabled a secure environment where internal video endpoints call and receive calls from external video endpoints.
How does the Expressway-C and Expressway-E communicate?

Refer to the exhibit. An administrator set up a B2B interop with a business partner running a Microsoft Lync environment and can successfully make outbound video calls to [email protected]. Inbound calls to [email protected], however, are failing. A quick SRV search returns the records in the exhibit. Which record must be modified to resolve this challenge?

Refer to the exhibit. After security policy updates, users in your organization report they cannot add external participants to newly created Webex App spaces but can still communicate with external users in older group spaces.
Investigation shows:
- External communication was recently restricted using "Allow selected domains only" in Control Hub.
- The allow list for domains is currently empty.
- No user groups are exempted from the restriction policy.
- Existing spaces that included internal and external members before the restriction still function normally.
What is the explanation for this behavior?

An administrator deployed the directory connector to synchronize the on-premises Active Directory with the Webex cloud and needs to map attributes from the AD to the corresponding attributes in the cloud. To which Webex cloud attribute must the user Account Control attribute be mapped to ensure that users are synced properly?

What is the last step for domain management in Cisco Webex Control Hub if an engineer adds users already signed in with the company domain?
