Question 21

Which Cisco Unified Communications Manager component groups devices that share common configuration settings such as region, date/time group, and SRST reference?

1. Route group
2. Device pool
3. Partition
4. Translation pattern

Correct Answer: 2

Explanation

A device pool groups devices that share common configuration settings in Cisco Unified Communications Manager. A device pool can reference items such as a Cisco Unified Communications Manager group, region, date/time group, SRST reference, and other device-related settings. Route groups organize gateways for routing purposes, partitions control dial-plan visibility, and translation patterns modify dialed numbers. Using device pools simplifies administration because common settings can be applied consistently to many endpoints. When troubleshooting phone registration or call behavior, administrators should verify the device pool and its associated configuration. Incorrect device-pool settings can affect registration, codec selection, failover behavior, and other endpoint operations.

Question 22

Which CUCM object is used to group directory numbers so that calling devices can be granted or denied access to them?

1. Partition
2. Device pool
3. Region
4. Route group

Correct Answer: 1

Explanation

A partition groups directory numbers, route patterns, translation patterns, and other dial-plan destinations so that calling search spaces can control access to them. A calling search space determines which partitions a device or user can search when placing a call. Device pools provide common device settings, regions control bandwidth and codec relationships, and route groups organize gateways. Partitions are therefore fundamental to implementing calling privileges and dial-plan separation. When users cannot reach a destination, administrators should verify both the destination’s partition and the caller’s calling search space. A mismatch between these two elements can prevent otherwise valid calls from being routed.

Question 23

Which CUCM configuration determines which partitions a device is allowed to search when placing a call?

1. Region
2. Route group
3. Calling Search Space
4. Device pool

Correct Answer: 3

Explanation

A Calling Search Space, or CSS, determines which partitions a device, line, or other calling entity can search when processing a dialed number. This provides an important mechanism for controlling calling privileges and implementing dial-plan segmentation. Regions define codec and bandwidth relationships, route groups organize gateways, and device pools provide common device configuration. A CSS can contain multiple partitions, and the order of those partitions can influence route selection when overlapping patterns exist. When troubleshooting a failed call, administrators should inspect the CSS assigned to the device or line and verify that it includes the partition containing the intended destination.

Question 24

Which CUCM feature modifies a dialed number before CUCM continues call processing?

1. Route group
2. Translation pattern
3. Device pool
4. Media resource group

Correct Answer: 2

Explanation

A translation pattern modifies a dialed number before CUCM continues processing the call. It can be used for digit manipulation, normalization, access-code removal, or routing-number transformation. Route groups organize gateways, device pools provide shared configuration, and media resource groups organize media resources. Translation patterns are useful when an organization’s internal dialing format differs from the number format required for routing. Administrators should carefully configure the pattern, partition, calling search space, and transformation settings. When troubleshooting unexpected digit changes, they should inspect translation patterns and other digit-manipulation features to determine which configuration modified the number before routing continued.

Question 25

Which Cisco collaboration component provides media resources such as conferencing and transcoding?

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

Correct Answer: 1

Explanation

Cisco Unified Communications Manager manages the configuration and use of media resources within a collaboration environment, including resources that may provide conferencing, transcoding, music on hold, and other media functions. Dedicated hardware or software resources can be registered and associated with CUCM through media resource configuration. Unity Connection focuses on voicemail, IM and Presence provides presence and messaging, and Expressway-E provides edge connectivity. Administrators use media resource groups and media resource group lists to control which resources devices can access. When conferencing or transcoding fails, checking resource registration, MRGL assignments, device configuration, and available resource capacity is an important troubleshooting step.

Question 26

Which protocol is used to carry real-time voice and video media after signaling establishes a session?

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

Correct Answer: 1

Explanation

Real-time Transport Protocol, or RTP, carries real-time audio and video media after signaling establishes a communication session. SIP commonly handles session signaling, while RTP transports the actual media streams. LDAP provides directory services, TFTP supports file transfer, and NTP provides time synchronization. RTP uses sequence numbers and timestamps to support proper playback and timing of media packets. When troubleshooting one-way audio, no audio, or degraded video, administrators should inspect the RTP path separately from the signaling path. Firewall rules, NAT, routing, codec negotiation, and media resource behavior can all affect successful RTP delivery.

Question 27

Which CUCM feature allows multiple gateways to be grouped together for routing purposes?

1. Route pattern
2. Route group
3. Partition
4. Calling Search Space

Correct Answer: 2

Explanation

A route group allows multiple gateways to be grouped together so that CUCM can select among them when routing calls. Route groups are commonly used with route lists and route patterns to create flexible and redundant outbound routing. A route pattern identifies dialed destinations, a partition controls visibility, and a calling search space determines which partitions can be searched. Administrators can assign multiple gateways to a route group and define their selection order or distribution behavior. When calls are not using the expected gateway, administrators should inspect the route pattern, route list, route group, gateway status, and any configured digit transformations.

Question 28

Which CUCM object combines route groups and provides a logical routing destination for route patterns?

1. Route list
2. Device pool
3. Partition
4. Region

Correct Answer: 1

Explanation

A route list provides a logical routing destination that can contain one or more route groups. Route patterns can point to a route list, allowing CUCM to select a suitable gateway from the associated route groups. This layered design separates dial-plan matching from gateway selection and supports redundancy. Device pools provide endpoint configuration, partitions control dial-plan visibility, and regions define bandwidth and codec relationships. When designing outbound routing, administrators can use route patterns to match numbers, route lists to define logical destinations, and route groups to identify actual gateways. This structure makes large enterprise dial plans easier to manage and troubleshoot.

Question 29

Which Cisco collaboration protocol is used by SIP endpoints to negotiate media parameters such as codecs and IP addresses?

1. DHCP
2. SDP
3. LDAP
4. SNMP

Correct Answer: 2

Explanation

Session Description Protocol, or SDP, describes multimedia session parameters during signaling. It can communicate information such as media types, codec capabilities, IP addresses, ports, and other session attributes. SIP commonly carries SDP information within signaling messages. DHCP provides network configuration, LDAP supports directory services, and SNMP is used for monitoring. SDP does not itself establish the call; instead, it helps endpoints and call-control systems agree on media characteristics. When troubleshooting codec negotiation or media failures, administrators should inspect SDP offers and answers to determine whether both endpoints selected compatible codecs, addresses, ports, and media parameters.

Question 30

Which Cisco collaboration mechanism is commonly used to provide backup call processing when a WAN connection to CUCM fails?

1. SRST
2. CDP
3. TFTP
4. LDAP

Correct Answer: 1

Explanation

Survivable Remote Site Telephony, or SRST, provides backup call-processing capabilities for supported Cisco IP phones at remote sites when communication with the centralized CUCM environment is unavailable. An SRST-capable router can provide basic telephony services during a WAN outage. CDP provides discovery, TFTP supports configuration files, and LDAP provides directory integration. SRST does not replicate the complete CUCM feature set; it focuses on maintaining essential telephony functionality during a failure. Administrators should configure the appropriate SRST reference and router settings and verify that phones can reach the backup service. Testing failover is important to confirm site survivability.

Question 31

Which CUCM object defines the relationship between two regions for codec selection and bandwidth limits?

1. Partition
2. Region
3. Route group
4. Device pool

Correct Answer: 2

Explanation

Regions define codec preferences and bandwidth relationships between groups of devices in CUCM. By configuring region relationships, administrators can control which codecs are preferred and how much bandwidth is allocated for audio and video calls between regions. Partitions control dial-plan visibility, route groups organize gateways, and device pools group common device configuration. Region configuration is particularly important in environments with constrained WAN bandwidth. When troubleshooting unexpected codec selection, administrators should verify the regions assigned to the endpoints and the codec relationship between those regions. Region settings can significantly influence media negotiation and bandwidth consumption across network links.

Question 32

Which Cisco collaboration protocol is primarily used for directory and user authentication integration with external directory servers?

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

Correct Answer: 3

Explanation

Lightweight Directory Access Protocol, or LDAP, is commonly used to integrate Cisco collaboration systems with external directory services. CUCM can use LDAP synchronization to import user information from directory systems such as Microsoft Active Directory. Depending on configuration, LDAP can also support user authentication. RTP carries real-time media, SIP provides session signaling, and SRTP protects real-time media. Proper LDAP integration requires correct server addresses, ports, credentials, search bases, filters, and network connectivity. When users are missing or authentication fails, administrators should review LDAP synchronization status, directory connectivity, search configuration, and authentication settings to identify the source of the problem.

Question 33

Which Cisco collaboration feature allows a phone to automatically receive its network address and provisioning information during startup?

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

Correct Answer: 1

Explanation

DHCP allows a Cisco IP phone to automatically obtain network configuration during startup. The phone can receive an IP address, subnet mask, default gateway, DNS information, and other parameters needed to operate on the network. Depending on the deployment, DHCP options can also provide information that helps the phone locate its TFTP server. SIP handles call signaling, SRTP secures media, and BGP is a routing protocol. If a phone fails to obtain an address or locate its provisioning server, administrators should check the correct voice VLAN, DHCP scope, relay configuration, DHCP options, and connectivity between the phone and DHCP infrastructure.

Question 34

Which Cisco collaboration security feature encrypts signaling between an IP phone and CUCM?

1. SRTP
2. TLS
3. RTP
4. CDP

Correct Answer: 2

Explanation

TLS can provide encrypted signaling between supported collaboration endpoints and Cisco Unified Communications Manager. It protects signaling information from unauthorized inspection or modification while it travels across the network. SRTP protects real-time media, RTP carries media without encryption by itself, and CDP provides device discovery. Secure signaling deployments depend on correctly configured security profiles, certificates, trust relationships, and system time. When a secure phone fails to register, administrators should verify certificate validity, TLS settings, device security profiles, and connectivity. Certificate hostname mismatches and expired certificates are common issues that can prevent secure signaling sessions from being established.

Question 35

Which CUCM feature controls the amount of bandwidth available between two regions for audio and video calls?

1. Calling Search Space
2. Partition
3. Region
4. Route List

Correct Answer: 3

Explanation

CUCM regions control codec selection and the amount of bandwidth allocated between regions for audio and video communication. This is especially useful when endpoints communicate across WAN links where bandwidth is limited. Administrators can define relationships between regions and specify preferred codecs and maximum audio or video bandwidth. Calling Search Spaces and partitions control dial-plan access, while route lists control gateway routing. If calls across a WAN are using an unexpected codec or consuming excessive bandwidth, administrators should examine the region assignments and the configured region-to-region relationship. Correct region planning helps balance media quality with available network capacity.

Question 36

Which Cisco collaboration component is designed to provide secure traversal between internal collaboration infrastructure and an external network?

1. Cisco Expressway
2. Cisco Unity Connection
3. Cisco IM and Presence
4. Cisco TFTP

Correct Answer: 1

Explanation

Cisco Expressway provides secure edge connectivity and traversal for collaboration traffic between internal systems and external networks. Expressway deployments can support remote access and collaboration scenarios while reducing the need to expose internal collaboration servers directly to the public network. Unity Connection provides voicemail, IM and Presence provides messaging and presence, and TFTP provides configuration files. In an Expressway traversal deployment, administrators must configure appropriate zones, traversal relationships, certificates, DNS, authentication, and firewall rules. Troubleshooting should examine both Expressway peers and the internal collaboration systems to determine whether signaling, authentication, or network connectivity is preventing successful communication.

Question 37

Which CUCM feature is used to automatically modify digits by adding or removing prefixes before routing a call?

1. Region
2. Device pool
3. Digit manipulation
4. Media resource group

Correct Answer: 3

Explanation

Digit manipulation allows CUCM to modify dialed numbers by adding, removing, or replacing digits before calls are routed. This capability is useful when internal dialing formats differ from the numbering format required by gateways or service providers. Digit manipulation can be configured through several dial-plan mechanisms, including route patterns, route lists, translation patterns, and route groups. Regions control media characteristics, device pools provide shared device settings, and media resource groups organize media resources. When a call reaches a provider with an incorrect number format, administrators should inspect the configured digit transformations and trace the number through each stage of CUCM call routing.

Question 38

Which protocol provides network time synchronization required for consistent timestamps across collaboration servers?

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

Correct Answer: 2

Explanation

NTP synchronizes clocks across collaboration servers, network devices, and other systems. Consistent time is important for authentication, certificates, logging, troubleshooting, database operations, and event correlation. SIP handles signaling, RTP carries media, and LDAP supports directory services. Collaboration deployments should use reliable and reachable NTP sources and maintain consistent time across clustered components. If servers have significantly different clocks, administrators may encounter certificate validation issues, authentication problems, misleading logs, or synchronization failures. During troubleshooting, verifying NTP status and the system clock should be part of the initial assessment when time-sensitive services or secure communications behave unexpectedly.

Question 39

Which Cisco collaboration component is primarily responsible for voicemail mailbox management and message storage?

1. Cisco Expressway
2. Cisco Unity Connection
3. Cisco CUBE
4. Cisco IM and Presence

Correct Answer: 2

Explanation

Cisco Unity Connection provides voicemail mailbox management and message storage within Cisco collaboration deployments. It supports voicemail access, message playback, notifications, call handlers, and integration with other messaging capabilities. Expressway provides edge connectivity, CUBE provides border voice functions, and IM and Presence provides presence and instant messaging. Unity Connection normally integrates with CUCM so that unanswered or busy calls can be redirected to the appropriate mailbox. When voicemail fails, administrators should check voicemail ports, CUCM routing, Unity Connection integration, mailbox configuration, message-store status, and network connectivity. Correct integration ensures calls are delivered to the intended voicemail service.

Question 40

Which CUCM feature determines which media resources a device can access?

1. Media Resource Group List
2. Calling Search Space
3. Route Group
4. Partition

Correct Answer: 1

Explanation

A Media Resource Group List, or MRGL, determines which media resources a device can access. MRGLs contain media resource groups, which in turn organize resources such as conference bridges, transcoders, music-on-hold resources, and other supported media services. Calling Search Spaces control dial-plan access, route groups organize gateways, and partitions organize destinations. If a device cannot access a required conference bridge or transcoder, administrators should inspect the device’s MRGL assignment and verify that the required resource is registered and available. Correct MRGL configuration helps ensure that endpoints receive appropriate media resources based on their location and operational requirements.
