1. Which complication does a NAT introduce in SDP for a SIP call?

2. A company already has a Cisco Unified Communications Manager for internal audio and video traffic, but it requires video communication with external partners and customers. It is important to ensure security for the deployment and the connectivity.

What must be set up to enable this requirement?

3. When an Expressway-E is configured for static NAT, which Session Description Protocol attribute is modified to reflect the NAT address?

4. A company is installing Cisco Collaboration infrastructure and one of the requirements is that they must be able to communicate with many external parties that are using H.323 and SIP. Internally they want to register the endpoints only on SIP.

Which functionality would describe the feature that needs to be enabled and where to achieve this?

5. What is a key configuration requirement for Hybrid Message Service High Availability deployment with multiple IM and Presence clusters?

6. Cisco Collaboration endpoints are exchanging encrypted signaling messages.

What is one major complication in implementing NAT ALG for voice and video devices?

7. What are two reasons why port 8443 is unreachable from the Internet to the Expressway-E? (Choose two.)

8. Which media encryption mode can be configured on an Expressway zone?

9. What is the purpose of a transform in the Expressway server?

10. An organization with a domain name of example.com.

Which two SRV records are valid for a SIP and H.323 communication? (Choose two.)

11. What is the Cisco-recommended key length in bits for a Cisco Expressway certificate?

12. Refer to the exhibit.

Which two numbers match the regular expression? (Choose two.)

13. A company has enabled ICE to optimize call flows and improve video quality between their Cisco Collaboration endpoints internally and externally.

For which reason would you see activity on the TURN server when a call is established between two external endpoints?

14. Which role does Call Policy play when preventing toll fraud on Expressways?

15. What happens to the encrypted signaling traffic of a collaboration device if you place it inside a firewall with private IP addresses and try to make a call over IP without any collaboration infrastructure?

16. Which statement about scheduling Expressway backups is true?

17. Between which two DTMF relay methods does the Expressway support interworking? (Choose two.)

18. What allows endpoints behind a NAT to discover the paths through which they will pass media?

19. Which two types of information does Cisco Expressway back up? (Choose two.)

20. Which connection does the traversal zone configuration de ne?

21. Which protocol should be used to verify the connectivity for different media paths found during a call using ICE?

22. Which SIP media encryption mode is applied by default for newly created zones in the Cisco Expressway?

23. 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?

24. Which dial plan component is configured in Expressway-C to route a call to the Cisco UCM?

25. Which attribute in the SDP for a call is affected by the static NAT address configuration in an Expressway-E?

26. Which describes what could done on the Expressway-E to successfully route calls from Expressway-C on the internal network to the Internet?

27. Refer to the exhibit.

What is the result of a transformation applied to alias 88514?

28. When configuring a Cisco Expressway solution and need to design the dial plan with various rules for URIs and numbers coming through the device. To do so, it is important that some dial plan rules are applied in a certain order. When configuring the transform section, you must know the range of the priorities.

Which range is correct?

29. Which zone is required on a B2B deployment between Expressway-C and Expressway-E?

30. Which mode should be used when Call Policy is configured on Expressways?

31. When designing the call control on a Cisco Expressway Core, which is the sequence of dial plan functions?

32. Which two items are configured when deploying a B2B collaboration solution? (Choose two.)

33. Which step is taken when configuring a Cisco Expressway solution?

34. Refer to the exhibit.

When configuring a search rule that routes calls to a zone, what occurs when 13358 is dialed?

35. Refer to the exhibit.

Which description of the transformation is true?

36. Refer to the exhibit.

In an environment SIP devices are registered to CUCM and H.323 devices to VCS.

What would be required to enable these calls to setup correctly?

37. Which step is required when configuring cloud and hybrid deployments for Cisco Jabber?

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

39. An Expressway-E is configured using a single NIC with NAT.

How must the Expressway-C traversal client zone be configured to connect to the Expressway-E?

40. Refer to the exhibit.

An ISDN gateway is registered to Expressway-C with a prefix of 9 and/or it has a neighbor zone specified that routes calls starting with a 9.

Which value should be entered into the "Source" eld to prevent toll fraud regardless at origin of the call?
