1Which Cisco collaboration deployment model places a single Cisco Unified Communications Manager (CUCM) cluster at a central data center and serves remote sites through the WAN?
A.Single-site deployment
B.Multisite with centralized call processing
C.Multisite with distributed call processing
D.Cloud (Webex Calling) deployment
Explanation: Multisite with centralized call processing keeps a single CUCM cluster at the headquarters and serves remote sites over the WAN. Survivable Remote Site Telephony (SRST) is typically added to provide call survivability if WAN connectivity is lost.
2A CUCM cluster has one Publisher and four Subscribers. What is the primary role of the Publisher?
A.Process all real-time call signaling for the cluster
B.Host the master read-write SQL database for the cluster
C.Provide media termination point services
D.Authenticate Jabber clients via OAuth
Explanation: The Publisher hosts the master read-write copy of the IBM Informix Dynamic Server (IDS) database that stores all CUCM configuration. Subscribers receive a read-only replicated copy and process call signaling. If the Publisher is down, Subscribers continue handling calls but cannot accept configuration changes.
3Which two design factors are MOST important when sizing a CUCM cluster for a new deployment? (Choose the BEST answer.)
A.Number of registered devices and Busy Hour Call Attempts (BHCA)
B.Number of Ethernet switches and VLANs
C.Cisco IOS XE version on the gateways
D.DHCP scope size at each branch
Explanation: CUCM cluster sizing uses two main metrics: total registered devices (phones, soft clients, gateways, conference resources) and BHCA, which measures call volume during the busiest hour. Cisco's CSR (Cisco Solutions Reference) and PA design guides translate those numbers into supported cluster topologies.
4An audio call uses the G.711 codec with a 20 ms packetization period over an Ethernet WAN. What is the approximate per-call bandwidth, including IP, UDP, RTP, and Layer 2 overhead?
A.24 kbps
B.64 kbps
C.About 80 kbps
D.About 160 kbps
Explanation: G.711 has a 64 kbps payload rate. With 20 ms packetization plus IP/UDP/RTP headers (40 bytes) and typical Layer 2 overhead, the call consumes approximately 80 kbps on Ethernet. CRTP or large-payload packetization changes the result, but 80 kbps is the canonical Cisco design figure.
5Which Cisco-recommended bandwidth value is commonly used for a G.722 (wideband) audio call at 20 ms packetization over Ethernet?
A.26 kbps
B.About 96 kbps
C.384 kbps
D.1.024 Mbps
Explanation: G.722 has a 64 kbps payload like G.711 but is wideband (50–7000 Hz). With IP/UDP/RTP and Layer 2 overhead at 20 ms packetization on Ethernet, Cisco's design guides quote approximately 96 kbps per call (the actual value depends on overhead model used).
6Which Cisco edge device is purpose-built as a Session Border Controller (SBC) on Cisco IOS XE for connecting to SIP trunk providers and Webex Calling Local Gateway?
A.Cisco Expressway-E
B.Cisco Unified Border Element (CUBE)
C.Cisco Unified Survivable Remote Site Telephony (SRST)
D.Cisco Meeting Server (CMS)
Explanation: Cisco Unified Border Element (CUBE) is the IOS XE-based SBC that interconnects CUCM or Webex Calling with ITSP SIP trunks, demarcates signaling/media, performs SIP normalization, and serves as the Local Gateway for Webex Calling Premises-based PSTN.
7In a Cisco collaboration deployment, which DNS record type does a Jabber or Webex App use to discover SIP/Expressway service hosts during MRA login?
A.A record only
B.PTR record
C.SRV record
D.MX record
Explanation: SIP service location uses DNS SRV records such as _collab-edge._tls.example.com to discover Expressway-E hosts during Mobile and Remote Access (MRA). SRV records return target host, port, priority, and weight, enabling redundancy and load balancing.
8Which network service must be accurate to within milliseconds across all CUCM nodes, gateways, and endpoints to ensure proper call detail records, certificate validation, and database replication?
A.DHCP
B.NTP
C.LDAP
D.TFTP
Explanation: Network Time Protocol (NTP) is required for time-sensitive operations such as CDRs, x.509 certificate validity windows, log correlation, and CUCM intra-cluster database replication. Cisco recommends syncing all collaboration nodes to the same authoritative NTP source.
9An engineer is troubleshooting why CUCM is not pulling user accounts from Active Directory. Which protocol is used between CUCM and the corporate directory for the synchronization process?
A.RADIUS
B.Kerberos
C.LDAP / LDAPS
D.SOAP only
Explanation: CUCM uses LDAP (or LDAPS for TLS-encrypted) to synchronize user objects from Active Directory or other directory servers. Once users are imported, CUCM can also enable LDAP authentication so passwords are validated against AD.
10Which two security technologies are part of CUCM's default security mode for encrypting signaling and media between phones and CUCM? (Choose the BEST single answer.)
A.IPsec for signaling and SRTP for media
B.TLS for signaling and SRTP for media
C.HTTPS for signaling and AES-CBC for media
D.SSH for signaling and ZRTP for media
Explanation: Cisco's default security framework uses TLS to encrypt SIP/SCCP signaling between endpoints and CUCM and SRTP (Secure RTP) to encrypt the media stream. Mixed-mode is no longer required for default phone security in modern CUCM versions, where Manufacturing Installed Certificates (MICs) and LSCs enable secure signaling out of the box.

Frequently Asked Questions

What is the Cisco 350-801 CLCOR v2.0 exam?

The 350-801 CLCOR (Implementing Cisco Collaboration Core Technologies v2.0) is the core exam for the CCNP Collaboration and CCIE Collaboration certifications, and on its own earns the Cisco Certified Specialist - Collaboration Core credential. The v2.0 blueprint became effective February 3, 2026, and increases coverage of Webex Calling, hybrid services, and Cloud Connected PSTN.

How long is the Cisco 350-801 CLCOR exam and how many questions does it have?

The exam is 120 minutes long with approximately 90-110 questions in multiple-choice, multi-select, drag-and-drop, and simulation formats. Cisco does not publish a fixed passing score; the score is reported on a 300-1000 scale and historical guidance suggests roughly 825/1000 is required.

What topics does the 350-801 CLCOR v2.0 exam cover?

v2.0 covers six domains: Infrastructure and Design (15%), Protocols and Endpoints (10%), On-Premises Call Control with CUCM (30%), Voice Gateways and Session Border Controllers (10%), Cloud and Hybrid Services with Webex Calling and Hybrid Services (25%), and Media/QoS (10%). Major topics include CUCM dial plans, CUBE Local Gateway, Webex Control Hub, Hybrid Calendar/Directory, Cloud Connected UC, SIP signaling, SDP, DTMF, certificates, OAuth, SSO, and LLQ-based QoS.

How much does the Cisco 350-801 CLCOR exam cost?

The exam fee is $400 USD per attempt and is administered through Pearson VUE testing centers or online proctoring. Cisco Learning Credits can be used to pay for the exam. If you fail, you must wait 5 calendar days before retaking; after passing, the same exam cannot be retaken for 180 days.

How long is the CCNP Collaboration certification valid after passing 350-801?

Cisco professional-level certifications are valid for 3 years. You can recertify by passing this same exam, an equivalent CCNP/CCIE exam, or by earning Continuing Education credits through Cisco's CE program before the certification expires.

Do I need experience to take the Cisco 350-801 CLCOR exam?

Cisco does not enforce formal prerequisites, but recommends 3-5 years of experience designing and implementing collaboration solutions including CUCM, Cisco voice gateways, CUBE, and Webex services. Hands-on lab time with CUCM, CUBE on IOS XE, Unity Connection, and Webex Control Hub significantly improves pass rates.

Should I study v1.1 or v2.0 for 2026?

The last test date for 350-801 v1.1 was February 2, 2026. From February 3, 2026 onward, all attempts use v2.0. v2.0 places greater emphasis on Webex Calling, Cloud Connected PSTN, Webex Hybrid Services, and Webex Control Hub administration, while reducing the weight given to legacy on-premises-only topics.
