CLCEI 300-820 is a 90-minute, ~60-question CCNP Collaboration concentration exam delivered by Pearson VUE for US$300. The v1.2 blueprint is weighted 25% Key Concepts, 25% Initial Expressway Configurations, 25% Mobile and Remote Access, and 25% Cisco Webex Technologies. There are no formal prerequisites, although Cisco recommends CCNA-level knowledge and hands-on collaboration deployment experience. Passing CLCEI alone earns the Cisco Certified Specialist - Collaboration Cloud and Edge Implementation credential, and combined with 350-801 CLCOR it earns the CCNP Collaboration certification. Cisco certifications remain valid for three years.

1Which Expressway role is positioned in the DMZ to terminate connections from the public Internet?
A.Expressway-C
B.Expressway-E
C.Cisco Unified Border Element (CUBE)
D.Unified Communications Manager (CUCM)
Explanation: Expressway-E (Edge) is the firewall-traversal server installed in the DMZ. It accepts inbound SIP/H.323 signaling and media from external endpoints and pairs with an Expressway-C inside the trusted network through a secure traversal zone.
2Where in an Expressway-C/Expressway-E pair is the traversal client zone configured?
A.On Expressway-E, pointing at Expressway-C
B.On Expressway-C, pointing at Expressway-E
C.On Cisco Unified Communications Manager
D.On both Expressways simultaneously
Explanation: The traversal client zone is created on the Expressway-C and points to the Expressway-E. Expressway-C initiates the outbound TCP connection to the Expressway-E so firewall rules only need to permit traffic from the trusted network outward to the DMZ.
3What is the default TCP/TLS port the Expressway-E listens on for the SIP leg of a Unified Communications traversal zone?
A.5060
B.5061
C.7001
D.6001
Explanation: By default the SIP port on a Unified Communications traversal zone is 7001 on both peers. Expressway-E listens on 7001 and Expressway-C connects outbound to that port; the firewall between the trusted network and DMZ must allow that flow.
4Which firewall-traversal protocol for H.323 is Cisco proprietary?
A.H.460.18
B.H.460.19
C.Assent
D.STUN
Explanation: Assent is Cisco's proprietary H.323 firewall-traversal protocol and predates the ITU standards. H.460.18 (signaling) and H.460.19 (media) are ITU standards built on the original Assent design.
5For SIP firewall traversal between Expressway-C and Expressway-E, which protocol is used for media?
A.H.460.19
B.Assent
C.TURN
D.H.460.18
Explanation: Expressway supports only the Assent protocol for SIP firewall traversal of media. SIP signaling is carried inside the TCP/TLS connection that the Expressway-C opens to the Expressway-E.
6What is the maximum number of peers supported in a single Cisco Expressway cluster?
A.2
B.4
C.6
D.8
Explanation: An Expressway cluster supports up to six peers. The cluster is identified by an FQDN configured on System > Clustering, and DNS SRV records and cluster certificates reference that cluster FQDN.
7When Expressway validates a peer's TLS certificate, which X.509 attribute does it check against the configured FQDN?
A.Subject Common Name (CN) only
B.Subject Alternative Name (SAN)
C.Issuer Common Name
D.Serial Number
Explanation: Expressway validates the received certificate using the Subject Alternative Name (SAN) extension, not the CN. Every required FQDN (peer FQDN, cluster FQDN, SIP domain, secure profile name, xmpp.<domain>) must therefore be listed in the SAN.
8Which DNS SRV record is queried by an external Jabber client to discover the Expressway-E for Mobile and Remote Access?
A._cisco-uds._tcp.<domain>
B._cuplogin._tcp.<domain>
C._collab-edge._tls.<domain>
D._sip._udp.<domain>
Explanation: _collab-edge._tls.<domain> is published in public DNS and resolves to the Expressway-E. Off-premises Jabber, Webex App, and supported endpoints use it to find the Expressway-E to traverse for MRA.
9An organization uses split DNS. Which record set should resolve only on the internal DNS servers?
A._collab-edge._tls.<domain>
B._cisco-uds._tcp.<domain> and _cuplogin._tcp.<domain>
C.Public CA root certificate chain
D.Expressway-E external IP A records
Explanation: _cisco-uds._tcp and _cuplogin._tcp are internal-only records that point Jabber to CUCM and IM&P when the client is on the corporate network. _collab-edge is published only externally so off-premises clients are pushed through MRA.
10What protocol does ICE rely on to discover a public-facing reflexive address for an endpoint behind NAT?
A.TURN
B.STUN
C.Assent
D.BFCP
Explanation: STUN (Session Traversal Utilities for NAT) lets a client probe a STUN server to learn its public (server-reflexive) address and port. ICE combines host, server-reflexive, and TURN-relayed candidates to pick a working media path.

Cisco CLCEI 300-820 Study Tips from Top Performers

1Build a small lab with Expressway-C and Expressway-E (CCO downloads or dCloud) so you can configure the Unified Communications traversal zone, certificate SANs, search rules, and transforms end-to-end.
2Memorize the default ports: SIP traversal 7001 TCP/TLS, H.323 Assent 6001, SIP 5060/5061, and Expressway-E media demultiplexing range starting at 36000 UDP - exam scenarios often hinge on those numbers.
3Drill Assent versus H.460.18 (signaling) and H.460.19 (media) for H.323 traversal, and remember Expressway only supports Assent for SIP traversal media.
4Practice MRA configuration: _collab-edge._tls in external DNS, _cisco-uds._tcp in internal DNS, certificate SANs (peer FQDN, cluster FQDN, xmpp.<domain>), and the SIP trunk security profile flags (Accept Replaces Header, Accept Out-of-Dialog REFER, Accept Unsolicited Notification, Accept Presence Subscription).
5Know the Webex Hybrid services map: Calendar Connector on Expressway-C for Exchange, cloud-only Graph for Microsoft 365, Directory Connector for AD sync, HDS for KMS, Webex Edge for Devices for cloud-managed CUCM endpoints, Webex Edge Connect for peering, and Local Gateway (CUBE) or CCP for Webex Calling PSTN.
