Free 300-820: Implementing Cisco Collaboration Cloud and Edge Solutions Exam Questions and Answers
Implementing Cisco Collaboration Cloud and Edge Solutions is exam 300-820, part of Cisco certifications. In Cisco's current scheme the first digit gives the level: 100 is entry, 200 associate, 300 the CCNP concentration exams, 350 the CCNP core exams that also qualify you for CCIE, 500 specialist and 700 the unproctored sales exams. Older codes such as 400-, 640- and 642- predate the February 2020 restructure, when every CCNA track was collapsed into one exam and CCNP moved to a core-plus-concentration model.

Question #1
When an Expressway-E is configured for static NAT, which Session Description Protocol attribute is modified to reflect the NAT address?
Please select an optionIncorrectCorrect answer: C
With static NAT enabled, Expressway-E rewrites the SDP connection line (c=) so the advertised media address is the public NAT address instead of the private LAN address; the m= line only carries ports and codecs.
Was this answer correct?Question #2
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?
Please select an optionIncorrectCorrect answer: C
Was this answer correct?Question #3
Which step is required when configuring Cisco Webex Hybrid Message Service?
Please select an optionIncorrectCorrect answer: A
Hybrid Message Service uses the Message Connector hosted on Expressway-C, so the Expressway-C connector host must first be registered to the Webex cloud before the connector can be installed and configured.
Was this answer correct?Question #4
Which describes what could done on the Expressway-E to successfully route calls from Expressway-C on the internal network to the Internet?
Please select an optionIncorrectCorrect answer: C
Expressway-E supports dual network interfaces so one NIC faces the internal network toward Expressway-C and the other faces the Internet, allowing traversal calls to be routed between the two networks.
Was this answer correct?Question #5
Which two statements about Cisco Webex Video Mesh Nodes are true? (Choose two.)
Select 2 answers.
Please select an optionIncorrectCorrect answer: B, D
Cloud-registered devices and apps run STUN reachability tests and pick the Video Mesh cluster with the lowest round-trip delay, while for on-premises SIP devices Unified CM route lists and route groups determine which node receives the signaling.
Was this answer correct?Question #6
Which media encryption mode can be configured on an Expressway zone?
Please select an optionIncorrectCorrect answer: D
Expressway zone media encryption modes include auto, force encrypted and force unencrypted; AES, IPsec and triple DES are encryption algorithms, not selectable zone modes.
Was this answer correct?Question #7
What is the purpose of a transform in the Expressway server?
Please select an optionIncorrectCorrect answer: D
Transforms operate on the alias itself, rewriting a destination alias that matches a pattern into another alias before search rules are applied; routing to a destination is the job of search rules and zones.
Was this answer correct?Question #8
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?
Please select an optionIncorrectCorrect answer: C
With a single NIC and static NAT, the traversal client zone on Expressway-C must point at the public NAT address of Expressway-E so that signaling and media are addressed consistently with what Expressway-E advertises.
Was this answer correct?Question #9
Refer to the exhibit. Cisco Unified Communications Manager routes the call via the Webex Meetings route list and route group to the Video Mesh cluster Node#1 in the Video Mesh cluster is hosting the meeting and has reached full capacity, but other nodes in the cluster still have spare capacity. What happens to the participant's call?
Please select an optionIncorrectCorrect answer: A
Video Mesh load-balances the participant to another node with spare capacity and forms an intra-cluster cascade between the two Video Mesh nodes, so the call still succeeds.
Was this answer correct?Question #10
An administrator has been asked to configure Video Mesh signaling traffic to route through a proxy. Which is an available proxy type in the Video Mesh node configuration to support this deployment model?
Please select an optionIncorrectCorrect answer: B
Video Mesh nodes support explicit proxy, transparent inspecting proxy and transparent non-inspecting proxy; the inspecting variant is chosen when the proxy decrypts and inspects the signaling traffic.
