Question 1

Which Cisco platform provides centralized call processing, device configuration, and dial-plan management in an on-premises collaboration environment?

1. Cisco Unity Connection
2. Cisco Unified Communications Manager
3. Cisco Expressway
4. Cisco IM and Presence

Correct Answer: 2

Explanation

Cisco Unified Communications Manager provides centralized call processing and manages many core components of an on-premises collaboration environment. It maintains configuration for phones, users, trunks, gateways, route patterns, calling privileges, and dial-plan elements. Cisco Unity Connection primarily provides voicemail and messaging functions, while Expressway supports edge connectivity and remote-access scenarios. Cisco IM and Presence provides presence and instant messaging capabilities. CUCM also integrates with other collaboration components to provide end-to-end communication services. Administrators use CUCM to configure endpoint registration, call routing, digit manipulation, calling search spaces, partitions, and other call-control features required for enterprise collaboration deployments.

Question 2

Which protocol is commonly used by Cisco IP phones to obtain their configuration files from Cisco Unified Communications Manager?

1. TFTP
2. LDAP
3. SNMP
4. NTP

Correct Answer: 1

Explanation

TFTP is commonly used by Cisco IP phones to retrieve configuration files and other required provisioning information. During phone startup, the device can obtain network parameters through DHCP and then use the configured TFTP server to download its configuration. LDAP is primarily used for directory integration and user synchronization, SNMP is used for monitoring and management, and NTP provides time synchronization. Correct TFTP configuration is important for successful phone registration and provisioning. Administrators troubleshooting a phone that cannot obtain configuration should verify DHCP options, TFTP reachability, DNS where applicable, and the configured CUCM TFTP service.

Question 3

Which protocol is designed to synchronize system clocks across Cisco collaboration servers and network devices?

1. LDAP
2. SIP
3. NTP
4. TFTP

Correct Answer: 3

Explanation

Network Time Protocol, or NTP, synchronizes system clocks across servers and network devices. Accurate time is important in collaboration environments because certificates, authentication mechanisms, logs, database replication, and troubleshooting activities can depend on consistent timestamps. LDAP handles directory services, SIP handles signaling, and TFTP provides file transfer and provisioning functions. Cisco collaboration deployments should use reliable NTP sources and maintain consistent time across the environment. When troubleshooting certificate or authentication problems, administrators should verify that system clocks are synchronized correctly. Incorrect time can cause certificates to appear invalid and can also make event correlation across multiple collaboration components difficult.

Question 4

Which signaling protocol is widely used for call setup, modification, and termination in modern Cisco collaboration deployments?

1. SIP
2. SNMP
3. DHCP
4. NTP

Correct Answer: 1

Explanation

Session Initiation Protocol, or SIP, is widely used for establishing, modifying, and terminating multimedia communication sessions. It handles signaling rather than carrying the actual voice or video media. SIP messages can negotiate session parameters through SDP and establish communication between endpoints, call-control systems, gateways, and other collaboration components. SNMP is primarily used for monitoring, DHCP provides network configuration, and NTP provides time synchronization. When troubleshooting SIP calls, administrators commonly inspect signaling messages, response codes, SDP information, and routing behavior. Understanding SIP call setup and teardown is essential for diagnosing registration, dialing, media-negotiation, and call-routing problems.

Question 5

Which codec generally provides high-quality wideband audio and is commonly associated with Cisco collaboration systems?

1. G.711
2. G.729
3. G.722
4. G.723

Correct Answer: 3

Explanation

G.722 is a wideband audio codec that provides higher audio quality than traditional narrowband codecs such as G.711. It is commonly used when endpoints and network conditions support wideband voice communication. G.711 provides high-quality narrowband audio but consumes more bandwidth than compressed codecs. G.729 provides compressed speech with lower bandwidth requirements, while G.723 is another low-bandwidth codec. Codec selection depends on available bandwidth, endpoint capabilities, quality requirements, and configured regions or negotiation policies. Administrators should verify that both endpoints support the selected codec and that the network can accommodate the associated media bandwidth.

Question 6

Which Cisco collaboration component is primarily responsible for providing voicemail and unified messaging services?

1. Cisco Expressway
2. Cisco Unity Connection
3. Cisco IM and Presence
4. Cisco Unified Border Element

Correct Answer: 2

Explanation

Cisco Unity Connection provides voicemail and unified messaging capabilities within Cisco collaboration environments. It integrates with Cisco Unified Communications Manager to provide voicemail access, message notification, call handlers, and related messaging features. Expressway provides collaboration edge functions, IM and Presence focuses on presence and instant messaging, and Cisco Unified Border Element provides voice and signaling connectivity at network boundaries. During deployment, administrators configure Unity Connection integration with CUCM and establish appropriate ports, SIP or SCCP connectivity, users, mailboxes, and call handlers. Troubleshooting commonly involves checking integration status, voicemail ports, routing, user configuration, and message delivery.

Question 7

Which Cisco technology enables remote users to access collaboration services without requiring a traditional VPN connection?

1. SRTP
2. Cisco Expressway Mobile and Remote Access
3. NTP
4. LDAP

Correct Answer: 2

Explanation

Cisco Expressway Mobile and Remote Access, commonly called MRA, allows supported collaboration endpoints to access internal collaboration services from outside the corporate network without requiring a traditional VPN. Expressway-E operates at the network edge while Expressway-C provides connectivity toward internal collaboration infrastructure. Security mechanisms such as TLS and certificates help protect signaling and authentication. SRTP protects media, NTP synchronizes time, and LDAP provides directory services. When troubleshooting MRA, administrators should verify DNS records, certificates, Expressway traversal configuration, CUCM settings, authentication, and network reachability. Correct edge architecture is essential for secure remote collaboration access.

Question 8

Which DNS record type is commonly used to identify the server providing a specific service and protocol?

1. A
2. PTR
3. MX
4. SRV

Correct Answer: 4

Explanation

An SRV record identifies servers that provide particular services and protocols and can include information such as the target hostname and port. Cisco collaboration deployments can use SRV records to help clients locate required collaboration services. An A record maps a hostname to an IPv4 address, a PTR record provides reverse DNS mapping, and an MX record identifies mail servers. Incorrect SRV records can cause clients to locate the wrong service or fail to discover required resources. Administrators troubleshooting collaboration service discovery should check DNS resolution, SRV records, target hostnames, ports, and corresponding A or AAAA records.

Question 9

Which security protocol protects signaling traffic by encrypting SIP communication between supported collaboration devices?

1. TLS
2. RTP
3. TFTP
4. DHCP

Correct Answer: 1

Explanation

Transport Layer Security, or TLS, can protect SIP signaling by encrypting the signaling connection between supported collaboration devices. This helps protect call-control information from being exposed or modified while it travels across the network. RTP carries real-time media, TFTP provides file transfer functions, and DHCP supplies network configuration. TLS relies on certificates to establish trust and authenticate participating systems. When troubleshooting secure SIP signaling, administrators should verify certificate validity, certificate chains, hostnames, trust stores, system time, and TCP connectivity. A certificate mismatch or expired certificate can prevent a secure signaling session from being established successfully.

Question 10

Which protocol provides secure encryption and authentication for real-time voice and video media?

1. SIP
2. SRTP
3. LDAP
4. SNMP

Correct Answer: 2

Explanation

Secure Real-time Transport Protocol, or SRTP, provides encryption, message authentication, and integrity protection for real-time voice and video media. It extends RTP with security capabilities designed for multimedia communication. SIP handles signaling and session control, LDAP supports directory integration, and SNMP is commonly used for monitoring. SRTP helps protect media from unauthorized interception and tampering during collaboration sessions. For successful secure-media communication, participating endpoints and intermediate devices must support compatible security settings. Administrators troubleshooting encrypted media should verify endpoint capabilities, security profiles, key negotiation, certificates where applicable, and whether the signaling process successfully establishes the required secure media parameters.

Question 11

Which Cisco collaboration feature allows users to be synchronized from an external directory service such as Microsoft Active Directory?

1. DHCP
2. LDAP integration
3. SRTP
4. TFTP

Correct Answer: 2

Explanation

LDAP integration allows Cisco Unified Communications Manager to synchronize users and related directory information from an external LDAP directory such as Microsoft Active Directory. This reduces the need to manually create and maintain every user account in CUCM. LDAP can also support authentication depending on the configured integration model. DHCP supplies network parameters, SRTP secures media, and TFTP provides configuration files. When LDAP synchronization fails, administrators should verify connectivity to the directory server, LDAP configuration, authentication credentials, search bases, filters, DNS resolution, and synchronization status. Correct LDAP integration helps maintain consistent user information across enterprise collaboration systems.

Question 12

Which Cisco collaboration component provides border connectivity between an enterprise voice network and external SIP service providers or networks?

1. Cisco Unified Border Element
2. Cisco Unity Connection
3. Cisco IM and Presence
4. Cisco TFTP

Correct Answer: 1

Explanation

Cisco Unified Border Element, or CUBE, provides border connectivity between enterprise collaboration environments and external voice networks or SIP service providers. It can provide functions such as SIP interworking, signaling normalization, topology hiding, security controls, and media handling. Unity Connection provides voicemail, IM and Presence provides messaging and presence, and TFTP supports provisioning. CUBE is often deployed between CUCM and a service provider or external SIP network. Troubleshooting CUBE connectivity involves checking SIP signaling, dial peers, routing, codecs, SIP profiles, NAT considerations, security policies, and media paths. Proper configuration ensures reliable communication across the network boundary.

Question 13

Which QoS marking is commonly associated with voice bearer traffic in an IP network?

1. AF11
2. CS1
3. EF
4. AF31

Correct Answer: 3

Explanation

Expedited Forwarding, or EF, is commonly used to mark real-time voice bearer traffic that requires low delay, low jitter, and low packet loss. Network devices can use this marking to place voice packets into an appropriate priority queue. AF11 and AF31 are other differentiated-services markings used for different traffic classes, while CS1 is commonly associated with lower-priority traffic. QoS marking alone does not guarantee quality; network devices must also classify, queue, schedule, and prioritize traffic correctly. Administrators should verify markings across network boundaries and ensure that WAN and LAN devices preserve the intended treatment for real-time media.

Question 14

Which Cisco Unified Communications Manager object is used to define the route that a call takes based on the dialed number?

1. Route pattern
2. Device pool
3. Softkey template
4. Phone button template

Correct Answer: 1

Explanation

A route pattern defines how CUCM processes calls based on dialed digits. It can direct calls toward gateways, trunks, route lists, or other destinations according to the configured dial plan. Device pools provide common device configuration, softkey templates control available softkeys, and phone button templates define phone button layouts. Route patterns are an important component of enterprise call routing because they determine how digit strings are matched and where calls are sent. When a call is routed incorrectly, administrators should inspect route patterns, partitions, calling search spaces, route lists, gateways, and digit manipulation settings to identify the routing decision causing the problem.

Question 15

Which protocol is used by DHCP clients to automatically obtain an IP address and other network parameters?

1. SIP
2. DHCP
3. LDAP
4. SRTP

Correct Answer: 2

Explanation

Dynamic Host Configuration Protocol, or DHCP, automatically provides clients with network configuration information such as IP addresses, subnet masks, default gateways, and DNS servers. Cisco IP phones can also receive additional provisioning information through DHCP options, depending on the deployment. SIP handles call signaling, LDAP provides directory services, and SRTP secures real-time media. DHCP is especially important during initial phone deployment because devices may depend on DHCP to obtain the information needed to reach their provisioning infrastructure. Troubleshooting should include checking DHCP scope availability, VLAN configuration, relay settings, options, address conflicts, and network connectivity between the phone and DHCP server.

Question 16

Which Cisco Unified Communications Manager feature is used to restrict which calls a user or device is allowed to place?

1. Calling Search Space
2. Device Pool
3. Region
4. Media Resource Group

Correct Answer: 1

Explanation

Calling Search Spaces, together with partitions, control which directory numbers and route patterns a device or user can access. They are commonly used to implement calling privileges and restrict access to specific destinations. A device pool provides common device configuration, regions influence codec selection and bandwidth characteristics, and media resource groups organize media resources. Administrators can use partitions and calling search spaces to separate internal, local, national, international, or restricted destinations. When a user receives a reorder tone or cannot dial a permitted destination, administrators should inspect the device’s calling search space, partition assignments, route patterns, and relevant calling permissions.

Question 17

Which Cisco collaboration component provides instant messaging and presence services in traditional on-premises deployments?

1. Cisco Unity Connection
2. Cisco Unified Border Element
3. Cisco IM and Presence
4. Cisco Expressway-E

Correct Answer: 3

Explanation

Cisco IM and Presence provides instant messaging and presence capabilities in traditional Cisco collaboration deployments. It integrates with Cisco Unified Communications Manager and can provide users with availability and presence information that helps determine whether colleagues are reachable. Unity Connection focuses on voicemail and messaging, CUBE provides network-border voice functions, and Expressway-E provides edge connectivity. Troubleshooting presence problems may involve checking CUCM integration, user synchronization, IM and Presence services, SIP or XMPP-related communication depending on the deployment, and network connectivity. Correct user configuration and service integration are important for reliable presence publication and subscription behavior.

Question 18

Which protocol is commonly used to advertise device identity and capabilities to directly connected Cisco network devices?

1. CDP
2. LDAP
3. SRTP
4. SIP

Correct Answer: 4

Explanation

Cisco Discovery Protocol, or CDP, allows Cisco devices to advertise information such as device identity, platform, interface details, and capabilities to directly connected Cisco devices. This information can help administrators understand network topology and troubleshoot connectivity. LDAP is used for directory services, SRTP protects media, and SIP provides call signaling. CDP is particularly useful when verifying that a Cisco IP phone is connected to the expected switch interface and when identifying neighboring Cisco equipment. Administrators should remember that CDP is primarily a discovery protocol and does not replace routing, signaling, or network configuration protocols required by collaboration systems.

Question 19

Which Cisco collaboration architecture provides a deployment model combining on-premises and cloud-based collaboration services?

1. Hybrid
2. Standalone
3. Isolated
4. Offline

Correct Answer: 1

Explanation

A hybrid collaboration architecture combines on-premises collaboration infrastructure with cloud-based services. This approach can allow organizations to retain selected existing systems while integrating cloud services and capabilities. The current CLCOR exam covers on-premises, hybrid, and cloud collaboration solution design elements, including infrastructure, security, bandwidth, high availability, and related technologies. Hybrid designs require careful planning around identity, connectivity, security, interoperability, and service responsibilities. Administrators must understand which components remain on premises and which services are delivered from the cloud. Proper architecture planning helps maintain reliable communication while organizations transition between deployment models.

Question 20

Which technology is primarily used to provide high availability by allowing collaboration services to continue operating when a component fails?

1. TFTP
2. LDAP
3. NTP
4. Redundancy and clustering

Correct Answer: 4

Explanation

Redundancy and clustering provide high availability by allowing collaboration services to continue operating when an individual component or server becomes unavailable. Cisco collaboration platforms can use clustered architectures and redundant components to improve service resilience. TFTP supports provisioning, LDAP provides directory integration, and NTP provides time synchronization; none of these technologies directly provide high availability. Effective high-availability design requires appropriate sizing, redundant infrastructure, network resiliency, and properly configured service relationships. Administrators should also understand failure scenarios and recovery procedures. High availability is particularly important for call-control systems because an infrastructure failure can affect registration, call processing, messaging, and other collaboration services.
