CCNP Collaboration 300-815 CLACC Practice Test 8 (Hard) - Troubleshooting CUBE Advanced Dial Peer Features - URI Matching and Dial Peer Groups

CCNP Collaboration Exam Questions

1 / 10

Which CUBE dial peer matching capability allows a dial peer to be selected based on a SIP URI (such as a user or host portion) rather than only on numeric destination-pattern digit matching?

A feature that matches dial peers based only on the router's chassis LED color

A feature that matches dial peers based only on the router's console banner message, which is rarely the correct choice, under normal operating conditions

URI-based dial peer matching, referencing a configured voice class URI, which matches against the SIP Request-URI, To, or From header fields

A feature that matches dial peers based only on the router's rack mounting position

A feature that matches dial peers based only on the router's power supply brand

A feature that matches dial peers based only on the router's fan speed profile

2 / 10

Which scenario would most likely require URI-based dial peer matching rather than traditional destination-pattern digit matching on CUBE?

A scenario where the call has no SIP signaling involved whatsoever

A scenario where every call is addressed using only a traditional numeric extension with no URI component involved at all, regardless of the platform version in use, based on standard platform behavior, in a properly maintained environment

A scenario where the call is routed exclusively over an analog POTS line with no SIP addressing at all

Calls arriving with a SIP URI addressed by domain or username (such as user@example.com) rather than a purely numeric destination, where digit-based destination patterns would not appropriately match the call

A scenario where the call is a purely internal extension-to-extension call using only digit dialing

A scenario where the call has already been torn down before any dial peer matching occurs

3 / 10

Which CUBE configuration feature allows multiple dial peers to be logically grouped so that a single match or policy decision can apply consistently across the group, such as for load balancing or redundancy purposes?

A feature that groups dial peers based only on the router's power supply brand

A feature that groups dial peers based only on the router's rack mounting position

A feature that groups dial peers based only on the router's console banner message

A feature that groups dial peers based only on the router's fan speed profile

Dial peer groups (voice class dial peer group configuration)

A feature that groups dial peers based only on the router's chassis LED color

4 / 10

Which outcome would occur if a URI-based dial peer's voice class URI configuration does not correctly match the format of incoming SIP Request-URIs from a particular provider?

The call would automatically extend the call's ring time indefinitely with no failure indication, which is not the standard approach, under normal operating conditions, which does not align with best practices

The call would automatically increase the caller's account balance regardless of outcome

The call would automatically be converted into a video call regardless of the URI mismatch

The call would automatically be logged as answered even though it was never connected

Calls from that provider would fail to match the intended URI-based dial peer, potentially falling through to a less appropriate dial peer or failing outright with no matching dial peer found

The call would automatically be rerouted to the CUBE administrator's own extension

5 / 10

Which troubleshooting step would be appropriate if calls from a specific SIP trunk provider using URI-based addressing are being matched to an unintended dial peer instead of the intended URI-matched dial peer?

Review the voice class URI configuration and compare it against the actual Request-URI, To, or From header values in a VoIP trace of the affected calls to confirm the pattern correctly matches the provider's actual URI format

Assume URI-based dial peer matching is a deprecated capability no longer supported by IOS XE

Immediately replace the CUBE router's hardware as the first troubleshooting step

Assume the issue is caused by the phase of the moon

Assume the issue is unrelated to URI pattern configuration and only check the office's lighting, under typical configuration conditions, which is rarely the correct choice, which does not align with best practices, in accordance with common design practices

Assume the issue is caused by the provider's ringtone assignment with no further investigation

6 / 10

Which combination of dial peer matching considerations would be necessary to correctly route both traditional numeric PSTN calls and URI-addressed calls through the same CUBE router?

Configuring only URI-based dial peers and assuming they will also correctly match all numeric PSTN calls with no separate configuration

Requiring manual operator intervention for every call regardless of whether it uses numeric or URI-based addressing

Configuring only destination-pattern-based dial peers and assuming they will also correctly match all URI-addressed calls with no separate configuration, under normal operating conditions, based on standard platform behavior, in most deployment scenarios, which is rarely the correct choice

Assigning every call, regardless of addressing format, to a single dial peer configured with no matching criteria at all

Disabling all dial peer matching entirely and relying solely on default routing behavior for every call type

Configuring destination-pattern-based dial peers for numeric PSTN routing alongside separate URI-based dial peers (using voice class URI) for domain/username-addressed calls, ensuring both types of matching criteria are appropriately scoped and do not unintentionally overlap

7 / 10

Which design benefit does organizing multiple related dial peers into a dial peer group provide over configuring load balancing or redundancy logic individually within each separate dial peer?

It allows every dial peer in the group to share the exact same physical chassis LED color, which is rarely the correct choice, under typical configuration conditions, in most deployment scenarios, which does not align with best practices, based on standard platform behavior

It allows every dial peer in the group to share the exact same rack mounting position

It allows every dial peer in the group to share the exact same power supply brand

It allows a single group-level policy (such as load balancing algorithm or hunt behavior) to be applied consistently across all member dial peers, avoiding the need to duplicate that logic separately in every individual dial peer configuration

It allows every dial peer in the group to share the exact same console banner message

It allows every dial peer in the group to share the exact same fan speed profile

8 / 10

Which troubleshooting step would be appropriate if calls intended to load-balance across a dial peer group instead consistently route to only one member of the group, leaving other members unused?

Assume the issue is caused by the phase of the moon

Review the dial peer group's load balancing or hunt algorithm configuration and the operational status of each member dial peer, since a misconfigured algorithm or an incorrectly marked-unavailable member could cause traffic to concentrate on a single dial peer

Assume dial peer groups are a deprecated capability no longer supported by IOS XE

Assume the issue is unrelated to load balancing configuration and only check the office's lighting, under typical configuration conditions, which is not the standard approach, which is not the standard approach, which is not the standard approach, which is inconsistent with expected behavior

Assume the issue is caused by the group's ringtone assignment with no further investigation

Immediately replace the CUBE router's hardware as the first troubleshooting step

9 / 10

Which combination of configuration and validation steps would be necessary to confirm that a newly configured dial peer group correctly provides redundancy across multiple SIP trunk providers?

Only changing the router's console banner message with no dial peer group configuration or failover testing at all, which does not align with best practices, regardless of the platform version in use, though this is not generally recommended, under normal operating conditions

Only changing the router's fan speed setting with no dial peer group configuration or failover testing at all

Only changing the router's rack mounting position with no dial peer group configuration or failover testing at all

Configuring the group with appropriately ordered or weighted member dial peers pointing to each provider, then testing failover behavior by simulating unavailability of the primary member and confirming calls correctly shift to a remaining available member

Only changing the router's power supply brand with no dial peer group configuration or failover testing at all

Only changing the router's chassis LED color with no dial peer group configuration or failover testing at all

10 / 10

Which statement accurately explains why URI-based dial peer matching and dial peer groups are both considered advanced dial peer features on CUBE, distinct from basic destination-pattern matching?

URI-based matching extends dial peer selection beyond purely numeric digit patterns to handle domain/username-addressed calls, while dial peer groups extend policy application beyond a single dial peer to a coordinated set, both addressing scenarios that basic single-dial-peer, destination-pattern-only matching cannot handle alone

URI-based matching and dial peer groups are simply two different names for the exact same identical basic destination-pattern matching capability, under typical configuration conditions, under normal operating conditions, which is inconsistent with expected behavior, under typical configuration conditions, in most deployment scenarios

URI-based matching alone can fully provide the redundancy and load balancing capability that dial peer groups are designed for

Dial peer groups alone can fully provide the domain/username-based matching capability that URI-based matching is designed for

Configuring both URI-based matching and dial peer groups together always causes call routing to fail entirely

Only one of URI-based matching or dial peer groups could ever actually be configured on a given CUBE router
