Question 81<\/b><\/h3>\n

Which CUCM feature allows an administrator to specify which codecs should be preferred between groups of devices?<\/b><\/p>\n

    \n
  1. Region<\/span><\/li>\n
  2. Partition<\/span><\/li>\n
  3. Route group<\/span><\/li>\n
  4. Device pool<\/span><\/li>\n<\/ol>\n

    Correct Answer: 1<\/b><\/p>\n

    Explanation<\/b><\/p>\n

    Regions in Cisco Unified Communications Manager define codec preferences and bandwidth relationships between groups of devices. Administrators can configure region-to-region relationships to influence which codec is selected when endpoints establish calls. This is particularly useful when devices communicate across WAN links with limited bandwidth. Partitions control dial-plan visibility, route groups organize gateways, and device pools provide shared configuration for endpoints. When a call uses an unexpected codec, administrators should verify the regions assigned to both endpoints and inspect the codec relationship between those regions. Proper region configuration helps balance voice and video quality with available network resources.<\/span><\/p>\n

    Question 82<\/b><\/h3>\n

    Which Cisco collaboration technology is used to provide voicemail services for CUCM users?<\/b><\/p>\n

      \n
    1. Cisco Expressway<\/span><\/li>\n
    2. Cisco CUBE<\/span><\/li>\n
    3. Cisco Unity Connection<\/span><\/li>\n
    4. Cisco IM and Presence<\/span><\/li>\n<\/ol>\n

      Correct Answer: 3<\/b><\/p>\n

      Explanation<\/b><\/p>\n

      Cisco Unity Connection provides voicemail services for users integrated with Cisco Unified Communications Manager. It manages mailboxes, voicemail messages, call handlers, message notifications, and voicemail access. CUCM can redirect unanswered, busy, or rejected calls to Unity Connection through the configured voicemail integration. Expressway provides edge connectivity, CUBE provides SIP border functions, and IM and Presence provides presence and instant messaging. When troubleshooting voicemail, administrators should check the CUCM voicemail configuration, ports, routing, Unity Connection integration, mailbox settings, and network connectivity. Proper integration ensures that calls are delivered to the correct mailbox and that users can retrieve their messages successfully.<\/span><\/p>\n

      Question 83<\/b><\/h3>\n

      Which CUCM feature determines the partitions that a calling device can search?<\/b><\/p>\n

        \n
      1. Device pool<\/span><\/li>\n
      2. Calling Search Space<\/span><\/li>\n
      3. Route group<\/span><\/li>\n
      4. Region<\/span><\/li>\n<\/ol>\n

        Correct Answer: 2<\/b><\/p>\n

        Explanation<\/b><\/p>\n

        A Calling Search Space determines which partitions a device, line, or user can search when processing a call. This provides a mechanism for implementing calling privileges and controlling access to destinations. Device pools provide common device configuration, route groups organize gateways, and regions manage codec and bandwidth relationships. Calling Search Spaces can contain multiple partitions, and their order can influence route selection when several destinations match a dialed number. If a user cannot reach an extension or external destination, administrators should verify the caller’s CSS and the partition assigned to the target. Correct CSS configuration is essential for predictable CUCM call routing.<\/span><\/p>\n

        Question 84<\/b><\/h3>\n

        Which protocol provides secure signaling for supported SIP connections?<\/b><\/p>\n

          \n
        1. RTP<\/span><\/li>\n
        2. SRTP<\/span><\/li>\n
        3. DHCP<\/span><\/li>\n
        4. TLS<\/span><\/li>\n<\/ol>\n

          Correct Answer: 4<\/b><\/p>\n

          Explanation<\/b><\/p>\n

          TLS provides encryption and authentication for supported SIP signaling connections. It protects signaling information such as call-control messages from unauthorized interception or modification. SRTP provides security for real-time media, RTP transports standard media, and DHCP provides network configuration. Secure SIP deployments depend on properly configured certificates, trust relationships, security profiles, and synchronized system time. When troubleshooting a secure SIP connection, administrators should inspect certificate validity, expiration dates, hostnames, trust chains, and network connectivity. It is important to distinguish signaling security from media security because TLS protects signaling while SRTP is used separately to protect the actual audio and video streams.<\/span><\/p>\n

          Question 85<\/b><\/h3>\n

          Which CUCM object provides a logical grouping of gateways for use by route lists?<\/b><\/p>\n

            \n
          1. Route group<\/span><\/li>\n
          2. Route pattern<\/span><\/li>\n
          3. Partition<\/span><\/li>\n
          4. Translation pattern<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation<\/b><\/p>\n

            A route group logically groups gateways that CUCM can use when routing calls. Route lists can reference route groups and provide a structured method for selecting primary and alternate gateways. Route patterns identify dialed-number patterns, partitions organize dial-plan destinations, and translation patterns modify digits. Route groups are particularly useful for redundancy because several gateways can be included in one logical routing group. When troubleshooting outbound calls, administrators should verify gateway registration and status, route-group membership, route-list configuration, route patterns, and any digit transformations. A properly configured route group helps CUCM select an available gateway according to the enterprise routing design.<\/span><\/p>\n

            Question 86<\/b><\/h3>\n

            Which Cisco protocol is responsible for carrying real-time audio after a call has been established?<\/b><\/p>\n

              \n
            1. SIP<\/span><\/li>\n
            2. RTP<\/span><\/li>\n
            3. LDAP<\/span><\/li>\n
            4. NTP<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2<\/b><\/p>\n

              Explanation<\/b><\/p>\n

              Real-time Transport Protocol, or RTP, carries real-time audio and video after signaling establishes a session. RTP uses sequence numbers and timestamps to help receivers process media in the correct order and timing. SIP provides call signaling, LDAP provides directory services, and NTP provides time synchronization. RTP is sensitive to network delay, jitter, and packet loss, so QoS and reliable network connectivity are important. If a call connects but has one-way audio or no audio, administrators should examine the RTP path separately from SIP signaling. Routing, firewall policies, NAT, codec compatibility, and media-resource configuration can all affect RTP delivery.<\/span><\/p>\n

              Question 87<\/b><\/h3>\n

              Which CUCM feature is used to change a dialed number before CUCM performs further call routing?<\/b><\/p>\n

                \n
              1. Route list<\/span><\/li>\n
              2. Translation pattern<\/span><\/li>\n
              3. Device pool<\/span><\/li>\n
              4. Region<\/span><\/li>\n<\/ol>\n

                Correct Answer: 2<\/b><\/p>\n

                Explanation<\/b><\/p>\n

                A translation pattern changes or transforms a dialed number before CUCM continues processing the call. It can remove access codes, add prefixes, or convert one numbering format into another. Route lists provide logical gateway-routing destinations, device pools group common device configuration, and regions control codec and bandwidth relationships. Translation patterns are evaluated within the CUCM dial plan and are affected by partitions and calling search spaces. When a call is being routed with unexpected digits, administrators should inspect translation patterns and other digit-manipulation configurations. Tracing the number through each routing stage helps identify where an incorrect transformation is occurring.<\/span><\/p>\n

                Question 88<\/b><\/h3>\n

                Which Cisco collaboration component provides remote-access connectivity for supported collaboration clients through the network edge?<\/b><\/p>\n

                  \n
                1. Cisco Unity Connection<\/span><\/li>\n
                2. Cisco Expressway<\/span><\/li>\n
                3. Cisco IM and Presence<\/span><\/li>\n
                4. Cisco TFTP<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 2<\/b><\/p>\n

                  Explanation<\/b><\/p>\n

                  Cisco Expressway provides edge connectivity for supported collaboration clients and endpoints accessing services from external networks. Expressway deployments can support Mobile and Remote Access while keeping internal collaboration systems protected behind the network boundary. Unity Connection provides voicemail, IM and Presence provides messaging and presence, and TFTP provides provisioning services. A typical MRA deployment uses Expressway-E at the edge and Expressway-C toward the internal collaboration environment. Troubleshooting should include DNS, certificates, traversal zones, authentication, CUCM configuration, firewall rules, and network reachability. Proper Expressway configuration allows remote users to access collaboration services securely without exposing internal systems directly.<\/span><\/p>\n

                  Question 89<\/b><\/h3>\n

                  Which CUCM object identifies a group of destinations that can be searched by a calling device?<\/b><\/p>\n

                    \n
                  1. Calling Search Space<\/span><\/li>\n
                  2. Route group<\/span><\/li>\n
                  3. Media Resource Group<\/span><\/li>\n
                  4. Device pool<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 1<\/b><\/p>\n

                    Explanation<\/b><\/p>\n

                    A Calling Search Space identifies the partitions that a calling device or user can search when placing a call. Because destinations such as directory numbers and route patterns can belong to specific partitions, CSS configuration controls which destinations are available. Route groups organize gateways, media resource groups organize media resources, and device pools provide common endpoint configuration. When troubleshooting a restricted call, administrators should verify the caller’s CSS and confirm that the intended destination’s partition is included. CSS configuration is one of the primary mechanisms used by CUCM to implement calling privileges and separate different classes of internal and external destinations.<\/span><\/p>\n

                    Question 90<\/b><\/h3>\n

                    Which protocol provides secure encryption for real-time media streams?<\/b><\/p>\n

                      \n
                    1. SRTP<\/span><\/li>\n
                    2. SIP<\/span><\/li>\n
                    3. LDAP<\/span><\/li>\n
                    4. DHCP<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 1<\/b><\/p>\n

                      Explanation<\/b><\/p>\n

                      Secure Real-time Transport Protocol, or SRTP, protects real-time audio and video by providing encryption, authentication, and integrity protection. It is used to secure media streams after signaling has negotiated the communication session. SIP handles signaling, LDAP supports directory integration, and DHCP provides network configuration. Secure media requires compatible endpoint capabilities and successful key negotiation. When troubleshooting an encrypted call, administrators should verify security profiles, endpoint capabilities, negotiated media parameters, and the media path. TLS and SRTP should not be confused: TLS protects signaling connections, while SRTP protects the actual real-time media transmitted during a voice or video session.<\/span><\/p>\n

                      Question 91<\/b><\/h3>\n

                      Which CUCM configuration groups devices that share common settings such as CUCM group and SRST reference?<\/b><\/p>\n

                        \n
                      1. Partition<\/span><\/li>\n
                      2. Route group<\/span><\/li>\n
                      3. Device pool<\/span><\/li>\n
                      4. Route pattern<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 3<\/b><\/p>\n

                        Explanation<\/b><\/p>\n

                        A device pool groups endpoints that require common configuration settings. It can define a CUCM group, region, date\/time group, SRST reference, and other parameters shared by multiple devices. Partitions organize dial-plan destinations, route groups organize gateways, and route patterns define digit-matching rules. Device pools simplify administration by allowing common settings to be applied consistently to many phones and endpoints. If multiple phones experience similar registration or failover behavior, administrators should check whether they share the same device pool and whether that pool contains the correct configuration. Proper device-pool design reduces repetitive configuration and improves consistency across collaboration endpoints.<\/span><\/p>\n

                        Question 92<\/b><\/h3>\n

                        Which protocol can be used by CUCM to synchronize user information with an external directory?<\/b><\/p>\n

                          \n
                        1. RTP<\/span><\/li>\n
                        2. SIP<\/span><\/li>\n
                        3. LDAP<\/span><\/li>\n
                        4. SRTP<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 3<\/b><\/p>\n

                          Explanation<\/b><\/p>\n

                          LDAP enables CUCM to integrate with external directory services and synchronize user information. Organizations commonly use LDAP with directory platforms such as Microsoft Active Directory. Synchronization can reduce manual user administration and maintain consistent identity information. RTP carries media, SIP provides signaling, and SRTP secures media. Administrators configuring LDAP should verify the directory server address, port, credentials, search base, filters, DNS resolution, and synchronization status. If users are missing from CUCM or directory authentication fails, these settings should be reviewed carefully. Successful LDAP integration can simplify user management across large enterprise collaboration environments.<\/span><\/p>\n

                          Question 93<\/b><\/h3>\n

                          Which Cisco collaboration technology provides backup call processing for supported IP phones when CUCM becomes unreachable?<\/b><\/p>\n

                            \n
                          1. SRST<\/span><\/li>\n
                          2. CUBE<\/span><\/li>\n
                          3. TFTP<\/span><\/li>\n
                          4. CDP<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 1<\/b><\/p>\n

                            Explanation<\/b><\/p>\n

                            Survivable Remote Site Telephony, or SRST, provides backup call-processing capabilities when supported Cisco IP phones lose connectivity to CUCM. It is generally implemented on a Cisco router at a remote site and allows essential telephony functions to continue during a WAN or centralized call-processing failure. CUBE provides SIP border connectivity, TFTP supports provisioning, and CDP provides device discovery. SRST does not reproduce every CUCM feature, so administrators should understand its supported functionality and limitations. Proper SRST deployment requires configuration on both CUCM and the router. Regular failover testing helps verify that phones can transition to the backup call-processing environment.<\/span><\/p>\n

                            Question 94<\/b><\/h3>\n

                            Which CUCM feature determines which codec and bandwidth settings apply between two groups of devices?<\/b><\/p>\n

                              \n
                            1. Region<\/span><\/li>\n
                            2. Partition<\/span><\/li>\n
                            3. Route group<\/span><\/li>\n
                            4. Calling Search Space<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 1<\/b><\/p>\n

                              Explanation<\/b><\/p>\n

                              Regions control codec preferences and bandwidth relationships between groups of devices in CUCM. Administrators can configure relationships between regions to influence codec selection and limit the amount of audio or video bandwidth used between them. This is especially important when collaboration traffic crosses WAN links with limited capacity. Partitions and calling search spaces control dial-plan access, while route groups organize gateways. If calls are using an unexpected codec or consuming too much bandwidth, administrators should inspect the region assigned to each endpoint and the relevant region-to-region relationship. Proper region configuration supports both voice quality and efficient network-resource utilization.<\/span><\/p>\n

                              Question 95<\/b><\/h3>\n

                              Which Cisco component provides a SIP boundary between an enterprise collaboration system and an external service provider?<\/b><\/p>\n

                                \n
                              1. Cisco Unity Connection<\/span><\/li>\n
                              2. Cisco IM and Presence<\/span><\/li>\n
                              3. Cisco Unified Border Element<\/span><\/li>\n
                              4. Cisco TFTP<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 3<\/b><\/p>\n

                                Explanation<\/b><\/p>\n

                                Cisco Unified Border Element, or CUBE, provides a SIP boundary between enterprise collaboration infrastructure and external networks such as SIP service providers. CUBE can provide signaling normalization, interoperability, topology hiding, security functions, and media handling. Unity Connection provides voicemail, IM and Presence provides presence and messaging, and TFTP supports provisioning. CUBE is commonly positioned between CUCM and an external SIP network. When troubleshooting a CUBE connection, administrators should inspect SIP signaling, dial peers, codec negotiation, routing, NAT, firewall policies, and media flow. Proper CUBE configuration helps isolate internal collaboration systems while providing controlled external voice connectivity.<\/span><\/p>\n

                                Question 96<\/b><\/h3>\n

                                Which protocol provides network time synchronization for Cisco collaboration servers?<\/b><\/p>\n

                                  \n
                                1. DHCP<\/span><\/li>\n
                                2. NTP<\/span><\/li>\n
                                3. SIP<\/span><\/li>\n
                                4. RTP<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 2<\/b><\/p>\n

                                  Explanation<\/b><\/p>\n

                                  Network Time Protocol, or NTP, synchronizes the clocks of collaboration servers and network devices. Consistent time is important for certificate validation, authentication, logging, database operations, and troubleshooting. DHCP provides network configuration, SIP handles signaling, and RTP carries real-time media. Collaboration systems should use reliable and reachable NTP sources. If system clocks differ significantly, administrators can encounter certificate problems, authentication failures, and confusing event timestamps. When troubleshooting time-related issues, administrators should verify the configured NTP servers, synchronization status, current system time, and network connectivity. Accurate time synchronization is an important foundation for stable and secure collaboration services.<\/span><\/p>\n

                                  Question 97<\/b><\/h3>\n

                                  Which CUCM object specifies the digit pattern used to match a particular outbound destination?<\/b><\/p>\n

                                    \n
                                  1. Route group<\/span><\/li>\n
                                  2. Device pool<\/span><\/li>\n
                                  3. Route pattern<\/span><\/li>\n
                                  4. Media Resource Group<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 3<\/b><\/p>\n

                                    Explanation<\/b><\/p>\n

                                    A route pattern specifies the digit pattern CUCM uses to match a particular outbound destination. After matching the dialed digits, CUCM can direct the call toward a route list, gateway, or other configured destination. Route groups contain gateways, device pools provide common endpoint settings, and media resource groups organize media resources. Route patterns are central to enterprise dial-plan implementation. When an outbound call fails or reaches an unexpected destination, administrators should inspect the dialed number, route pattern, partition, calling search space, route list, route group, and digit manipulation. Understanding the complete routing path makes CUCM call-routing troubleshooting more efficient.<\/span><\/p>\n

                                    Question 98<\/b><\/h3>\n

                                    Which Cisco collaboration service provides instant messaging and user availability information?<\/b><\/p>\n

                                    4. Cisco Expressway-E<\/span><\/li>\n<\/ol>\n

                                      Correct Answer: 3<\/b><\/p>\n

                                      Explanation<\/b><\/p>\n

                                      Cisco IM and Presence provides instant messaging and user presence information in supported Cisco collaboration environments. Presence allows users to see availability states, while instant messaging enables real-time text communication. CUBE provides SIP border functions, Unity Connection provides voicemail, and Expressway-E provides edge connectivity. IM and Presence integrates with CUCM and user information sources to support collaboration features. If presence information is incorrect or unavailable, administrators should verify user configuration, CUCM integration, service status, directory synchronization, and network connectivity. Proper integration ensures that presence states can be published and subscribed to by authorized collaboration users.<\/span><\/p>\n

                                      Question 99<\/b><\/h3>\n

                                      Which CUCM component groups media resources such as conference bridges and transcoders?<\/b><\/p>\n

                                        Correct Answer: 1<\/b><\/p>\n

                                        Explanation<\/b><\/p>\n

                                        A Media Resource Group, or MRG, groups media resources such as conference bridges, transcoders, music-on-hold resources, and other supported media services. MRGs can be placed into Media Resource Group Lists, which are then assigned to devices and other collaboration components. Route lists organize gateway routing, partitions organize dial-plan destinations, and calling search spaces control access to partitions. If a device cannot access a conference bridge or transcoder, administrators should check its MRGL, the associated MRG, and the registration status of the media resource. Proper MRG configuration helps administrators control and organize media-resource availability across the collaboration environment.<\/span><\/p>\n

                                        Question 100<\/b><\/h3>\n

                                        Which protocol is responsible for session establishment and termination in a SIP-based Cisco collaboration environment?<\/b><\/p>\n

                                        4. LDAP<\/span><\/li>\n<\/ol>\n

                                          Correct Answer: 3<\/b><\/p>\n

                                          Explanation<\/b><\/p>\n

                                          SIP is responsible for establishing, modifying, and terminating communication sessions in SIP-based collaboration environments. SIP signaling uses messages such as INVITE, ACK, BYE, and CANCEL to control different stages of a session. RTP carries the actual real-time media, TFTP supports provisioning, and LDAP provides directory services. SIP can also carry SDP information used to negotiate media characteristics. When troubleshooting a call, administrators should inspect SIP signaling separately from the RTP media path because successful signaling does not guarantee successful audio or video. Routing, firewall rules, NAT, codec negotiation, and media-resource configuration can all affect the final communication experience.<\/span><\/p>\n
