Question 201

Which CUCM object is primarily used to control access to partitions for a device or user?

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

Correct Answer: 2

Explanation

A Calling Search Space controls which partitions a device, line, or user can access when CUCM processes a call. It consists of an ordered list of partitions and is a fundamental component of CUCM dial-plan design. When a user dials a number, CUCM checks the caller’s CSS to determine whether the destination partition is searchable. Route lists manage gateway routing, device pools provide shared endpoint configuration, and media resource groups organize media resources. If a user can dial internal numbers but cannot reach certain external destinations, checking the assigned CSS and the target partition is an important troubleshooting step.

Question 202

Which SIP response code commonly indicates that the destination is busy?

1. 404
2. 200
3. 503
4. 486

Correct Answer: 4

Explanation

SIP response code 486 Busy Here generally indicates that the called endpoint is busy and cannot accept the incoming call. This response belongs to the 4xx client-failure class of SIP responses. A 200 response indicates successful processing, 404 indicates that the requested resource was not found, and 503 indicates service unavailability. When troubleshooting busy-call behavior, administrators should examine the SIP signaling sequence and determine which device generated the response. Other call-forwarding, hunt, voicemail, or call-waiting configurations can also affect the final behavior. Understanding common SIP responses helps identify where call processing stopped.

Question 203

Which CUCM feature is used to match a dialed digit pattern and route the call toward a gateway or route list?

1. Route Pattern
2. Device Pool
3. Region
4. Media Resource Group

Correct Answer: 1

Explanation

A Route Pattern defines a digit pattern that CUCM uses to identify and route calls. The pattern can point toward a route list, gateway, or other routing destination depending on the configuration. Route patterns are central to CUCM dial-plan design because they determine how dialed numbers are interpreted and routed. Device pools provide common endpoint settings, regions control codec and bandwidth relationships, and media resource groups organize media resources. When an outbound call is not routing correctly, administrators should verify the dialed digits, route pattern, partition, Calling Search Space, route list, route group, and digit manipulation configuration.

Question 204

Which component provides SIP-to-PSTN border connectivity and can perform protocol or header manipulation?

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

Correct Answer: 3

Explanation

Cisco Unified Border Element, or CUBE, provides border functionality between enterprise collaboration systems and external SIP networks such as service providers. It can perform SIP interworking, topology hiding, header manipulation, security functions, and media handling. Unity Connection focuses on voicemail, Expressway-C supports internal edge collaboration functions, and IM and Presence provides messaging and presence services. When external calls fail, administrators should inspect CUBE dial peers, SIP profiles, codec settings, signaling, NAT, firewall policies, and service-provider requirements. Proper CUBE configuration allows an enterprise to maintain controlled and interoperable SIP connectivity with external networks.

Question 205

Which CUCM configuration allows administrators to group endpoints that require similar common settings?

1. Translation Pattern
2. Device Pool
3. Route Pattern
4. Partition

Correct Answer: 2

Explanation

A Device Pool groups endpoints that require similar common configuration settings. It can reference items such as a CUCM Group, region, date/time group, SRST reference, and other settings used by multiple devices. This approach reduces repetitive configuration and makes administration easier across large deployments. Translation patterns modify dialed digits, route patterns identify routing destinations, and partitions organize dial-plan objects. When deploying phones at multiple locations, administrators can create appropriate device pools for each site or endpoint group. Reviewing the device pool is also useful when troubleshooting registration, codec, failover, or regional behavior because several important endpoint settings may be inherited from it.

Question 206

Which protocol is designed to synchronize clocks across network devices?

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

Correct Answer: 1

Explanation

Network Time Protocol, or NTP, synchronizes system clocks across network devices. Accurate time is important in Cisco collaboration environments because timestamps are used for logs, certificates, authentication, troubleshooting, and event correlation. RTP carries real-time media, SIP provides signaling, and DHCP supplies network configuration information. If collaboration systems have inconsistent system times, administrators may encounter certificate validation problems or difficulty correlating events across multiple servers. NTP should therefore be configured consistently across CUCM, Unity Connection, Expressway, CUBE, and other relevant systems. Reliable time synchronization makes troubleshooting easier and supports proper operation of security mechanisms.

Question 207

Which media resource is commonly required when two endpoints cannot use a mutually supported codec?

1. Music on Hold
2. Conference Bridge
3. Annunciator
4. Transcoder

Correct Answer: 4

Explanation

A transcoder converts media from one codec to another when communicating endpoints do not share a mutually supported codec. For example, one endpoint may use G.711 while another network segment requires a different codec. The transcoder provides the necessary media conversion so the call can continue. A conference bridge provides multiparty conferencing, Music on Hold supplies audio during hold conditions, and an annunciator provides prerecorded or system-generated announcements. If calls establish signaling but fail during media negotiation because of codec incompatibility, administrators should inspect regions, codec preferences, media resource availability, and the configured Media Resource Group and MRGL.

Question 208

Which SIP method is normally used to terminate an established dialog?

1. OPTIONS
2. REGISTER
3. BYE
4. INVITE

Correct Answer: 3

Explanation

The SIP BYE method is used to terminate an established SIP session. When one endpoint ends an active call, it sends a BYE request to indicate that the dialog should be terminated. INVITE is used to establish or modify a session, REGISTER is used to register an endpoint with a SIP registrar, and OPTIONS can be used to query capabilities or availability. During troubleshooting, administrators can inspect SIP traces to determine whether a BYE was sent normally or whether another device unexpectedly terminated the session. This distinction can help identify endpoint, routing, trunk, or intermediary problems affecting call duration.

Question 209

Which CUCM feature can be used to add or remove digits before sending a call to another destination?

1. Translation Pattern
2. Device Pool
3. Region
4. Route Group

Correct Answer: 1

Explanation

A Translation Pattern can manipulate dialed digits before CUCM continues call processing. It can add, remove, or transform digits according to configured patterns and calling privileges. Translation patterns are useful when enterprise dialing formats differ from those required by gateways, service providers, or other systems. Device pools provide shared endpoint settings, regions influence media characteristics, and route groups organize gateways. When troubleshooting calls that reach an incorrect destination or present an unexpected number, administrators should inspect translation patterns along with route patterns, partitions, CSS settings, and other digit-manipulation features. Properly designed translation patterns help maintain consistent and flexible dial plans.

Question 210

Which protocol is commonly used by Cisco IP phones to discover network information about directly connected Cisco switches?

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

Correct Answer: 1

Explanation

Cisco Discovery Protocol, or CDP, allows Cisco devices to discover information about directly connected Cisco neighbors. Cisco IP phones can use CDP to learn information from compatible network switches, including voice VLAN information in supported deployments. LDAP is used for directory services, TLS protects signaling or other application traffic, and SRTP protects real-time media. When a Cisco phone is not receiving the expected voice VLAN configuration, administrators should check switch-port configuration, CDP status, voice VLAN settings, and the phone’s network behavior. CDP is particularly useful in Cisco environments because it provides operational information about directly connected infrastructure.

Question 211

Which codec is known for providing wideband speech quality in Cisco collaboration environments?

1. G.729
2. G.711
3. G.722
4. G.726

Correct Answer: 3

Explanation

G.722 is a wideband audio codec commonly used to provide improved speech quality compared with traditional narrowband codecs. It can provide a wider audio frequency range and is supported by many Cisco collaboration endpoints. G.711 is a common high-bandwidth narrowband codec, G.729 provides compressed narrowband audio, and G.726 is another legacy audio codec. Codec selection can depend on endpoint capabilities, region configuration, bandwidth availability, and interoperability requirements. When troubleshooting voice quality or unexpected codec negotiation, administrators should review region settings, endpoint capabilities, SIP or SDP negotiation, and any transcoding requirements along the media path.

Question 212

Which CUCM object determines which gateways are considered when a route list is used?

1. Partition
2. Route Group
3. Device Pool
4. Region

Correct Answer: 2

Explanation

A Route Group contains one or more gateways and determines the gateway resources that can be selected when CUCM uses that route group for call routing. Route Lists can contain multiple route groups, allowing administrators to create ordered routing and redundancy strategies. Partitions control dial-plan visibility, device pools provide common endpoint settings, and regions control codec and bandwidth relationships. When an outbound call uses an unexpected gateway, administrators should trace the routing hierarchy from the route pattern to the route list and then to the route group. Gateway status, distribution algorithms, and digit manipulation should also be checked when troubleshooting routing behavior.

Question 213

Which service is responsible for directory-based user authentication and information retrieval in many Cisco collaboration deployments?

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

Correct Answer: 1

Explanation

Lightweight Directory Access Protocol, or LDAP, is commonly used to integrate collaboration systems with enterprise directory services. LDAP can provide centralized user information and, depending on the deployment, support user authentication and directory synchronization. RTP carries real-time media, NTP synchronizes system clocks, and SRTP secures media. LDAP integration can simplify user administration by allowing organizations to maintain identity information in a centralized directory. When users cannot authenticate or directory information appears incorrect, administrators should inspect LDAP server reachability, synchronization status, credentials, filters, mappings, and network connectivity. Correct LDAP configuration supports consistent user identity information across collaboration applications.

Question 214

Which Expressway component normally provides the external-facing edge function for Mobile and Remote Access?

1. Expressway-C
2. CUCM
3. Unity Connection
4. Expressway-E

Correct Answer: 4

Explanation

Expressway-E normally provides the external-facing edge function in a Mobile and Remote Access deployment. It communicates with Expressway-C through a secure traversal relationship and provides controlled connectivity for remote collaboration clients. Expressway-C is generally deployed inside the enterprise network and connects toward internal collaboration services. CUCM provides call processing, while Unity Connection provides voicemail. Troubleshooting MRA commonly involves DNS records, certificates, traversal zones, firewall policies, search rules, authentication, and CUCM integration. Proper separation between Expressway-E and Expressway-C helps protect internal collaboration resources while allowing authorized remote clients to access supported services.

Question 215

Which CUCM object organizes destinations into logical groups that can be referenced by Calling Search Spaces?

1. Device Pool
2. Partition
3. Route Group
4. Media Resource Group

Correct Answer: 2

Explanation

A Partition organizes CUCM dial-plan destinations into logical groups. Directory numbers, route patterns, translation patterns, and other objects can be assigned to partitions. Calling Search Spaces then determine which partitions a device, line, or user is permitted to search. Device pools provide shared configuration settings, route groups organize gateways, and media resource groups organize media resources. If a destination is unreachable even though the correct number appears to exist, administrators should verify the destination’s partition and the caller’s CSS. Proper partition design allows organizations to control dialing privileges and separate different classes of destinations within the CUCM dial plan.

Question 216

Which technology provides encrypted protection for real-time voice and video media?

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

Correct Answer: 3

Explanation

Secure Real-time Transport Protocol, or SRTP, provides encryption and integrity protection for real-time voice and video media. It is designed specifically for RTP-based traffic and helps protect media from unauthorized interception or modification. TLS is generally used to protect signaling or other application communications, LDAP provides directory services, and SIP handles session signaling. In a secure collaboration deployment, administrators may need both TLS and SRTP because signaling and media have different security requirements. When secure media fails, administrators should verify endpoint security capabilities, security profiles, certificate relationships where applicable, and successful media-security negotiation.

Question 217

Which CUCM resource provides audio prompts and tones generated by the system?

1. Transcoder
2. Annunciator
3. Conference Bridge
4. Music on Hold

Correct Answer: 2

Explanation

The Cisco CUCM Annunciator provides system-generated audio announcements and tones for supported call-processing functions. It is a media resource that can be used when CUCM needs to provide announcements to callers. A transcoder converts between codecs, a conference bridge supports multiparty conferencing, and Music on Hold provides audio while a caller is placed on hold. Media resources are commonly organized through Media Resource Groups and Media Resource Group Lists. If a system announcement or tone is unavailable, administrators should verify that the required media resource is registered and reachable and that the endpoint has access to the appropriate MRGL.

Question 218

Which CUCM configuration can provide alternate call-processing servers for endpoint registration and redundancy?

1. Partition
2. Route Pattern
3. CUCM Group
4. Translation Pattern

Correct Answer: 3

Explanation

A CUCM Group contains an ordered list of CUCM servers that endpoints can use for registration and call processing. It is an important component of CUCM redundancy because endpoints can use alternate servers when their preferred server becomes unavailable. Device pools reference CUCM Groups, allowing administrators to apply consistent server-selection policies to groups of devices. Partitions, route patterns, and translation patterns are related to dial-plan processing rather than server registration redundancy. When investigating registration failover, administrators should inspect the phone’s device pool, CUCM Group order, server availability, network connectivity, TFTP information, and endpoint registration status.

Question 219

Which SIP method is used by an endpoint to register its contact information with a SIP registrar?

1. REGISTER
2. BYE
3. INVITE
4. CANCEL

Correct Answer: 1

Explanation

The SIP REGISTER method allows an endpoint to register its contact information with a SIP registrar. Registration tells the system where the endpoint can currently be reached and may include information such as the endpoint’s SIP address and contact location. INVITE is used to establish or modify sessions, BYE terminates an established dialog, and CANCEL stops a pending request such as an unanswered INVITE. When a SIP endpoint cannot receive calls, administrators should inspect registration status, authentication, DNS, network reachability, registrar configuration, and expiration intervals. Understanding REGISTER transactions is essential when troubleshooting endpoint availability and SIP registration failures.

Question 220

Which CUCM feature determines the maximum bandwidth relationship between regions for audio or video calls?

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

Correct Answer: 2

Explanation

CUCM Regions define codec preferences and bandwidth relationships between groups of devices. Administrators can configure region-to-region settings to control the maximum audio and video bandwidth used between regions and influence codec selection. This is particularly useful when endpoints communicate across WAN connections with limited capacity. Route lists and route groups control gateway routing, while Calling Search Spaces control access to partitions. When collaboration traffic consumes excessive WAN bandwidth or endpoints negotiate unexpected codecs, administrators should inspect region assignments and region relationships. Proper region configuration helps balance media quality, codec behavior, and available network resources across distributed collaboration deployments.
