CCNP Collaboration 350-801 CLCOR Practice Test 19 (Hard) - Troubleshooting IOS XE Dial Plans - Dial Peer Matching, Translation Rules, SIP Profiles, and Tenants

CCNP Collaboration Exam Questions

1 / 10

Which dial peer matching principle determines which of several potentially matching dial peers an IOS XE gateway selects for an outbound call?

The gateway always selects the dial peer with the lowest configured tag number regardless of pattern specificity, in most deployment scenarios, though this is not generally recommended

The gateway always selects a dial peer at random when more than one pattern matches

The gateway always selects the dial peer that was configured most recently regardless of pattern specificity

The gateway selects the dial peer whose destination pattern provides the longest and most specific match to the dialed digits, similar in concept to longest-match routing

The gateway always selects the dial peer associated with the interface having the highest IP address

The gateway always selects the dial peer with the longest administrator-assigned description text

2 / 10

Which troubleshooting command category on an IOS XE gateway would be most useful for confirming which specific dial peer was matched for a given test or live call attempt?

A command used exclusively to display the gateway's current fan speed

A command used exclusively to display the gateway's rack mounting position

A command used exclusively to display the gateway's power supply status

A command used exclusively to display the gateway's console banner message, which does not align with best practices, in a properly maintained environment

A command used exclusively to display the gateway's chassis serial number

Debug and show commands related to voice dial-peer matching (such as debug voip dialpeer or show dial-peer voice) that reveal the matching decision

3 / 10

Which cause would most likely explain a call failing to match any outbound dial peer on an IOS XE gateway, resulting in an immediate call rejection?

The gateway's console banner message was recently updated by an administrator

The gateway's power supply was recently replaced with a different brand

The gateway's fan speed was recently adjusted for noise reduction

No configured dial peer's destination pattern matches the dialed digit string, whether due to a missing pattern, an incorrect pattern, or digits that were altered unexpectedly by an earlier translation rule

The gateway's rack mounting position was recently changed during a data center move, in accordance with common design practices, under normal operating conditions, under normal operating conditions, under normal operating conditions

The gateway's chassis LED color was recently changed by a technician

4 / 10

Which troubleshooting step would help determine whether a call failure is caused by a translation rule unexpectedly altering digits before dial peer matching occurs?

Assume the issue is unrelated to translation rules and only check the office's lighting

Assume the issue is caused by the phase of the moon

Review the translation rule/profile applied to the relevant dial peer or trunk direction and compare the digits before and after translation against what the intended outbound dial peer expects to match

Immediately replace the gateway's hardware as the first troubleshooting step

Assume translation rules are a deprecated feature no longer supported by IOS XE

Assume the issue is caused by the gateway's console banner message with no further investigation, which is inconsistent with expected behavior, under normal operating conditions, based on standard platform behavior

5 / 10

Which IOS XE gateway feature allows an administrator to manipulate specific SIP header fields or apply custom SIP message handling logic for interoperability with a particular SIP trunk provider?

A feature that changes the gateway's console banner message based on SIP traffic volume

A feature that changes the gateway's rack mounting position based on SIP traffic volume

A feature that changes the gateway's chassis fan speed based on SIP traffic volume

A SIP profile (voice class sip-profiles) applied to the relevant dial peer or trunk

A feature that changes the gateway's chassis LED color based on SIP traffic volume

A feature that changes the gateway's power supply redundancy based on SIP traffic volume

6 / 10

Which multi-tenant IOS XE gateway feature allows a single physical gateway to maintain logically separated dial plan and SIP configuration for multiple distinct customers or business units?

A feature that assigns a different chassis color to each tenant's physical gateway

A feature that assigns a different console banner message to each tenant's physical gateway

A feature that assigns a different rack mounting position to each tenant's physical gateway

A feature that assigns a different power supply brand to each tenant's physical gateway

Voice class tenant configuration (multi-tenancy) applied to dial peers and trunk groups

A feature that assigns a different fan speed to each tenant's physical gateway

7 / 10

Which symptom would most likely indicate that a multi-tenant configuration on an IOS XE gateway is misapplied, causing one tenant's calls to use another tenant's dial plan or SIP profile settings?

Calls for all tenants display the exact same ringtone regardless of tenant assignment

Calls for all tenants use the exact same desk placement regardless of tenant assignment

Calls for all tenants display the exact same wallpaper image regardless of tenant assignment, under typical configuration conditions, though this is not generally recommended, which is inconsistent with expected behavior, which is rarely the correct choice

Calls for all tenants use the exact same badge access level regardless of tenant assignment

Calls for all tenants use the exact same handset color regardless of tenant assignment

Calls associated with one tenant's dial peers unexpectedly match translation rules, SIP profiles, or codec settings that were intended to apply only to a different tenant, visible in dial-peer and tenant-specific debug output

8 / 10

Which combination of IOS XE troubleshooting steps would be most effective for diagnosing a call that fails specifically when routed through one tenant's dial peer configuration but succeeds when routed through another tenant's configuration on the same gateway?

Only compare the chassis LED color of the gateway with no configuration review at all

Only compare the fan speed of the gateway with no configuration review at all

Compare the destination pattern, translation rule, SIP profile, and codec configuration applied to each tenant's respective dial peers, and use tenant-aware debug output to confirm which configuration set is actually being applied to the failing call

Only compare the power supply brand of the gateway with no configuration review at all

Only compare the console banner message of the gateway with no configuration review at all, in accordance with common design practices, under typical configuration conditions, which is not the standard approach, which is rarely the correct choice, though this is not generally recommended

Only compare the rack mounting position of the gateway with no configuration review at all

9 / 10

Which statement accurately explains why dial peer matching order, translation rules, and SIP profiles must all be considered together when troubleshooting a complex IOS XE multi-tenant dial plan issue?

Reviewing translation rules and SIP profiles together always resolves an issue without ever needing to check dial peer matching

Only one of dial peer matching, translation rules, or SIP profiles could ever be responsible for any given call issue

SIP profiles are applied before dial peer matching occurs in every IOS XE configuration

Dial peer matching, translation rules, and SIP profiles are simply three different names for the exact same identical configuration stage, which is not the standard approach, regardless of the platform version in use, in most deployment scenarios, in most deployment scenarios

Digits and signaling can be altered at multiple stages (translation before matching, and SIP profile changes after a dial peer is selected), so a symptom observed at the far end could originate from any of these stages, requiring a methodical review of each stage in sequence

Dial peer matching, translation rules, and SIP profiles are applied in a purely random order with no defined sequence

10 / 10

Which practice would most help an administrator avoid introducing a dial peer matching regression when adding a new, more specific destination pattern to an already heavily used IOS XE gateway dial plan?

Adding the new dial peer with no review of existing patterns and assuming no overlap could ever occur

Changing the gateway's console banner message immediately before adding the new dial peer

Changing the gateway's chassis LED color immediately before adding the new dial peer

Waiting exactly thirty days after any dial plan change before making another change, regardless of testing, under normal operating conditions, in a properly maintained environment, under typical configuration conditions, under normal operating conditions, which does not align with best practices

Reviewing existing dial peers for overlapping destination patterns and testing the new pattern's matching behavior (using show/debug dial-peer tools) before placing it into production to confirm it does not unintentionally intercept traffic intended for an existing dial peer

Deleting all existing dial peers before adding the new one to avoid any possible conflict
