Question 61

Which CUCM feature allows administrators to associate multiple directory numbers with a single physical IP phone?

1. Route group
2. Device pool
3. Multiple lines
4. Region

Correct Answer: 3

Explanation

Cisco Unified Communications Manager allows multiple directory numbers to be configured on a single IP phone. Each line can have its own directory number and associated configuration, allowing one physical device to handle multiple identities or extensions. Route groups are used for gateway selection, device pools provide common device settings, and regions control codec and bandwidth relationships. Multiple lines are useful for executives, shared phones, administrative users, and devices requiring several extensions. When configuring multiple lines, administrators should consider directory number partitions, calling search spaces, line settings, and user associations. Proper configuration ensures each line receives the intended calling privileges and behavior.

Question 62

Which Cisco collaboration protocol is primarily responsible for transporting voice packets across an IP network?

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

Correct Answer: 1

Explanation

Real-time Transport Protocol, or RTP, carries voice and video packets across IP networks after a communication session has been established. RTP provides sequence numbers and timestamps that help receivers process real-time media correctly. SIP is primarily responsible for call signaling, LDAP supports directory services, and TFTP provides file-transfer capabilities used in provisioning. RTP traffic is sensitive to delay, jitter, and packet loss, so network quality is important for acceptable voice communication. When troubleshooting voice quality, administrators should examine the RTP path, QoS treatment, routing, packet loss, latency, jitter, NAT, and firewall policies rather than focusing only on SIP signaling.

Question 63

Which CUCM feature is used to provide a fallback call-processing destination for phones during a CUCM server failure?

1. Route list
2. SRST
3. Partition
4. Translation pattern

Correct Answer: 2

Explanation

Survivable Remote Site Telephony, or SRST, provides backup call-processing capabilities for supported Cisco IP phones when connectivity to CUCM is lost. SRST functionality is typically provided by a Cisco router at the remote location. It allows essential telephony services to continue during WAN or centralized call-processing failures. Route lists handle gateway selection, partitions organize dial-plan destinations, and translation patterns modify numbers. Administrators should configure the appropriate SRST reference in CUCM and verify the corresponding router configuration. Testing failover is important because SRST does not provide every feature available from CUCM. Its primary purpose is maintaining essential telephony operations during an outage.

Question 64

Which CUCM object is used to determine whether a caller can access a specific partition?

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

Correct Answer: 4

Explanation

A Calling Search Space determines which partitions a caller can search when processing a dialed number. This mechanism allows administrators to control calling privileges and separate different classes of destinations. Device pools provide common configuration, route groups organize gateways, and regions control codec and bandwidth relationships. A CSS can contain multiple partitions, and the order of those partitions can affect route selection when multiple matching destinations exist. When a caller cannot reach an expected number, administrators should verify the caller’s CSS, the destination partition, and any route pattern involved. Correct CSS design is fundamental to implementing secure and predictable enterprise dial plans.

Question 65

Which protocol can be used to securely encrypt SIP signaling between supported collaboration systems?

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

Correct Answer: 3

Explanation

Transport Layer Security, or TLS, can secure SIP signaling between supported Cisco collaboration systems and endpoints. TLS encrypts signaling information and can provide authentication through certificate-based trust relationships. RTP transports real-time media, SRTP secures that media, and DHCP provides network configuration. Secure SIP deployments require properly configured security profiles, certificates, trust stores, and synchronized system time. When troubleshooting a TLS connection, administrators should verify certificate validity, certificate chains, hostnames, expiration dates, and network reachability. A successful secure signaling connection does not automatically mean media is encrypted; SRTP must be separately supported and negotiated for secure media transport.

Question 66

Which CUCM object provides a logical collection of gateways that can be referenced by a route list?

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

Correct Answer: 1

Explanation

A route group is a logical collection of gateways that can be referenced by a route list. Route groups allow CUCM to select among multiple gateways and can provide redundancy or alternate routing paths. A route pattern identifies the digits to be matched, a partition controls dial-plan visibility, and a device pool groups common endpoint configuration. When an outbound call is not using the expected gateway, administrators should inspect the route pattern, route list, route group, gateway status, and digit transformations. Proper route-group configuration helps ensure that CUCM can select an available gateway according to the organization’s routing strategy and failover requirements.

Question 67

Which Cisco collaboration component provides centralized management of voicemail users, mailboxes, and call handlers?

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

Correct Answer: 2

Explanation

Cisco Unity Connection provides centralized voicemail services, including mailbox management, user voicemail configuration, call handlers, message access, and notification features. It commonly integrates with CUCM so unanswered or busy calls can be redirected to the appropriate mailbox. Expressway provides edge connectivity, CUBE handles external SIP or voice-border functions, and IM and Presence provides presence and instant messaging. When troubleshooting voicemail, administrators should verify the CUCM integration, voicemail ports, user mailbox configuration, call routing, and Unity Connection service status. Proper configuration ensures that calls reach the correct mailbox and that users can access and manage their messages.

Question 68

Which CUCM feature groups multiple devices so they can inherit common configuration parameters?

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

Correct Answer: 2

Explanation

A device pool groups devices that require common configuration parameters. It can provide shared settings such as the CUCM group, region, date/time group, SRST reference, and other device-related values. Partitions organize dial-plan destinations, route groups organize gateways, and translation patterns modify dialed numbers. Device pools simplify administration because common settings can be applied consistently to many phones or endpoints. When devices exhibit unexpected registration, codec, or failover behavior, administrators should verify the assigned device pool and its associated configuration. Correct device-pool design helps maintain consistency across endpoints while reducing repetitive configuration work.

Question 69

Which protocol provides directory integration between CUCM and an external directory such as Microsoft Active Directory?

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

Correct Answer: 1

Explanation

LDAP provides directory integration between CUCM and external directory services such as Microsoft Active Directory. CUCM can synchronize user information from the directory, reducing the need to manually create and maintain every user account. Depending on the configuration, LDAP can also support user authentication. RTP handles real-time media, SIP provides signaling, and SRTP protects media. Administrators troubleshooting LDAP synchronization should verify directory-server reachability, credentials, search bases, filters, ports, DNS resolution, and synchronization status. Proper LDAP integration helps maintain consistent user information across collaboration platforms and can simplify account administration in large enterprise environments.

Question 70

Which CUCM configuration is used to define the maximum bandwidth available between two regions for video calls?

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

Correct Answer: 4

Explanation

Region configuration determines codec preferences and bandwidth relationships between groups of endpoints. Administrators can configure maximum audio and video bandwidth between regions to control how collaboration traffic uses network resources. This is particularly important across WAN connections where bandwidth may be limited. Partitions and calling search spaces control dial-plan access, while route groups organize gateways. When video calls consume more bandwidth than expected, administrators should examine the regions assigned to the endpoints and the configured region-to-region relationship. Proper region design allows organizations to balance video quality against available network capacity and helps maintain predictable collaboration performance.

Question 71

Which Cisco technology provides secure remote access to collaboration services without requiring a traditional VPN for supported clients?

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

Correct Answer: 2

Explanation

Cisco Expressway Mobile and Remote Access, or MRA, enables supported collaboration clients and endpoints to access internal collaboration services from external networks without requiring a traditional VPN. The architecture commonly uses Expressway-E at the network edge and Expressway-C toward the internal collaboration environment. Certificates, DNS, authentication, and traversal configuration are important components of a successful deployment. SRTP protects media, NTP provides time synchronization, and LDAP supports directory integration. Troubleshooting MRA should include checking DNS records, certificates, Expressway traversal zones, CUCM configuration, authentication, and firewall connectivity. Properly designed MRA provides secure remote collaboration access while keeping internal systems protected.

Question 72

Which protocol is commonly used to discover Cisco devices connected directly to a network interface?

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

Correct Answer: 1

Explanation

Cisco Discovery Protocol, or CDP, allows Cisco devices to advertise information about themselves to directly connected Cisco devices. It can provide details such as device identity, platform, interface information, and capabilities. SIP handles call signaling, NTP provides time synchronization, and LDAP supports directory services. CDP can be useful when troubleshooting Cisco IP phone connectivity because administrators can verify the switch interface and identify the directly connected device. CDP is a discovery mechanism rather than a routing or signaling protocol. Administrators should also understand that CDP information is locally exchanged and should be appropriately managed according to the organization’s security requirements.

Question 73

Which CUCM object defines a logical group of partitions that a device can search when placing calls?

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

Correct Answer: 2

Explanation

A Calling Search Space is a logical collection of partitions that determines which destinations a device or user can access during call processing. CSS configuration is central to CUCM calling privileges because a directory number or route pattern is generally reachable only when its partition is included in the caller’s search space. Route lists control gateway routing, device pools provide shared device settings, and regions manage codec and bandwidth relationships. When troubleshooting a restricted or failed call, administrators should examine both the destination partition and the caller’s CSS. Proper CSS design allows organizations to implement controlled access to internal, local, national, and international destinations.

Question 74

Which Cisco collaboration protocol carries encrypted real-time voice media when secure media is negotiated?

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

Correct Answer: 3

Explanation

Secure Real-time Transport Protocol, or SRTP, carries encrypted and authenticated real-time voice and video media. It extends RTP by adding security features that protect media from interception and tampering. SIP is primarily used for signaling and session control, RTP provides standard real-time media transport, and DHCP supplies network configuration. Secure media requires compatible endpoint capabilities and successful negotiation of the required security parameters. When troubleshooting encrypted calls, administrators should verify security profiles, endpoint capabilities, signaling negotiation, and media-path connectivity. It is important to distinguish secure signaling through TLS from secure media through SRTP because they protect different parts of a collaboration session.

Question 75

Which CUCM object identifies the digit pattern that should be used for a specific call-routing decision?

1. Route pattern
2. Route group
3. Device pool
4. Media Resource Group

Correct Answer: 1

Explanation

A route pattern defines the digit pattern CUCM uses to identify a specific call-routing decision. Once a dialed number matches the pattern, CUCM can route the call toward an appropriate route list, gateway, or other configured destination. Route groups contain gateways, device pools provide shared device configuration, and media resource groups organize media resources. Route patterns are therefore a fundamental element of enterprise dial-plan architecture. Administrators troubleshooting call-routing problems should check the dialed digits, route pattern, partition, calling search space, route list, route group, and digit manipulation. Overlapping patterns should also be reviewed because they can affect which route is selected.

Question 76

Which technology allows CUCM to modify the number dialed by a user before routing it to the next destination?

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

Correct Answer: 2

Explanation

A translation pattern allows CUCM to modify a dialed number before continuing call processing. It can remove access codes, add prefixes, transform internal numbers into externally routable numbers, or perform other digit manipulation. Regions manage codec and bandwidth behavior, device pools provide common endpoint configuration, and route groups organize gateways. Translation patterns are evaluated as part of the CUCM dial plan and are affected by partitions and calling search spaces. When users report that calls are being sent with incorrect digits, administrators should trace the number through translation patterns, route patterns, route lists, and gateway transformations to identify where the modification occurred.

Question 77

Which Cisco collaboration component provides SIP border functionality between CUCM and a service provider?

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

Correct Answer: 3

Explanation

Cisco Unified Border Element, or CUBE, provides SIP border functionality between enterprise collaboration infrastructure and external SIP networks such as service providers. CUBE can provide signaling normalization, interoperability, topology hiding, security controls, and media handling. IM and Presence provides presence and messaging, Unity Connection provides voicemail, and Expressway-E provides collaboration edge functions for supported scenarios. Troubleshooting CUBE usually involves examining SIP signaling, dial peers, codec negotiation, routing, NAT, security policies, and media flow. CUBE provides an important boundary between internal and external voice environments and can help control how SIP sessions are exchanged across that boundary.

Question 78

Which protocol is used to synchronize the clocks of CUCM, Unity Connection, and other collaboration servers?

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

Correct Answer: 2

Explanation

NTP synchronizes the system clocks of collaboration servers and network devices. Consistent time is important for authentication, certificates, database operations, logging, troubleshooting, and event correlation. SIP provides signaling, RTP carries real-time media, and LDAP supports directory integration. Administrators should configure reliable NTP sources and verify synchronization across all collaboration components. If system clocks drift significantly, certificates can appear invalid and authentication or database operations may be affected. During troubleshooting, administrators should check the configured NTP source, synchronization state, current system time, and network reachability to the time source. Reliable time synchronization is a fundamental infrastructure requirement.

Question 79

Which CUCM configuration groups media resources such as conference bridges and transcoders for assignment through an MRGL?

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

Correct Answer: 1

Explanation

A Media Resource Group, or MRG, groups media resources such as conference bridges, transcoders, and other supported media services. MRGs are then placed into Media Resource Group Lists, which can be assigned to devices and other collaboration components. Route groups organize gateways, partitions organize dial-plan destinations, and calling search spaces determine which partitions can be searched. When a device cannot access a conference bridge or transcoder, administrators should verify the device’s MRGL, the MRG membership, and the registration status of the required media resource. Proper media-resource grouping provides administrators with control over resource availability and helps organize collaboration infrastructure.

Question 80

Which protocol provides the session signaling used to establish a voice call between SIP-enabled collaboration endpoints?

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

Correct Answer: 3

Explanation

SIP provides the signaling used to establish, modify, and terminate voice sessions between SIP-enabled collaboration endpoints and call-control systems. SIP signaling communicates information required to initiate the session and negotiate media parameters, often using SDP. RTP subsequently carries the actual voice media. DHCP provides network configuration and TFTP supports provisioning and configuration-file transfer. When troubleshooting a SIP call, administrators should examine registration status, SIP messages, response codes, SDP negotiation, routing, and authentication. A successful SIP session does not automatically guarantee good audio because RTP follows a separate media path that can be affected by routing, firewalls, NAT, QoS, and codec compatibility.
