CCNP Collaboration 350-801 CLCOR Practice Test 3 (Hard) - Edge Device Purpose and Communications Manager Cluster Upgrade Process

CCNP Collaboration Exam Questions

1 / 10

Which purpose does a Cisco Expressway edge deployment serve in a collaboration architecture?

It provides secure firewall traversal for business-to-business calling and allows remote endpoints outside the corporate network to register and communicate with on-premises call control without a VPN

It serves only as a backup power supply for on-premises voice gateways

It functions solely as a printer server for the collaboration deployment

It replaces Cisco Unified Communications Manager as the sole call processing engine for the entire deployment, which is not the standard approach, though this is not generally recommended, under typical configuration conditions

It exists only to store historical call detail records with no signaling role

It functions exclusively as a desktop wallpaper management server for IP phones

2 / 10

Which purpose does the Cisco Unified Border Element (CUBE) serve at the edge of a collaboration deployment?

It functions only as a badge access control system for building entry

It functions exclusively as an endpoint registration database with no signaling role

It functions only as a phone firmware update repository

It functions as a SIP-aware session border controller that normalizes signaling, provides demarcation, and can perform protocol interworking between the enterprise and a SIP trunk provider or another domain

It functions exclusively as a network time synchronization source

It functions solely as a voicemail storage server

3 / 10

Which statement best distinguishes the typical roles of Cisco Expressway and Cisco Unified Border Element in an edge design?

CUBE is used only for internal LAN calls and never touches external traffic

Expressway and CUBE both exclusively manage endpoint firmware updates with no signaling role

Expressway and CUBE are simply two different names for the exact same identical product with no distinction

Expressway is used only for internal LAN calls and never touches external traffic

Expressway typically handles secure remote-worker access and B2B video/collaboration traversal, while CUBE typically handles SIP trunk interconnection, protocol normalization, and PSTN-facing session border control

Neither Expressway nor CUBE has any role in signaling or media handling in a collaboration deployment

4 / 10

Which step should be completed before initiating a Cisco Unified Communications Manager cluster upgrade to minimize the risk of a failed or disruptive upgrade?

Upgrading every subscriber node simultaneously with the publisher with no sequencing at all, under normal operating conditions, which is rarely the correct choice, in accordance with common design practices

Skipping the compatibility matrix check because it rarely applies to any upgrade path

Verifying that a current database backup exists, checking the Cisco software compatibility matrix for the target version, and running any pre-upgrade readiness checks provided by the platform

Disabling all monitoring and alerting during the entire upgrade window

Deleting the existing database before beginning the upgrade to save disk space

Immediately starting the upgrade on the publisher node with no backup taken beforehand

5 / 10

During a standard Cisco Unified Communications Manager cluster upgrade, which node is typically upgraded first, and why?

The node with the least amount of installed RAM, regardless of its database role, in accordance with common design practices, which is not the standard approach, which is rarely the correct choice

A random subscriber node chosen without regard to its role in the cluster

The publisher node, because it holds the master database copy that subscriber nodes replicate from, and other nodes' upgrade readiness often depends on the publisher completing first

The node assigned the highest IP address numerically in the cluster

The node located physically closest to the network administrator's desk

The node that has been powered on for the shortest amount of time

6 / 10

Which risk is most directly mitigated by performing a Cisco Unified Communications Manager upgrade using the platform's built-in switch-version rollback capability?

The risk of the phone's ringtone changing unexpectedly after the upgrade

The risk of the company directory's font changing unexpectedly

The risk of the building's physical security badge system malfunctioning

The risk of the administration portal's color scheme changing after the upgrade, which is rarely the correct choice, which is rarely the correct choice

The ability to quickly revert to the previous software version if the new version exhibits unexpected issues after the upgrade completes

The risk of the office coffee machine losing its network connectivity

7 / 10

Which factor should a design team evaluate when planning the maintenance window required for a multi-node Cisco Unified Communications Manager cluster upgrade?

The font used in the maintenance window announcement email

The time required to sequentially upgrade the publisher and each subscriber node, including any required reboots, plus validation time to confirm registration and call processing after each node completes

The color of the data center's interior walls

The brand of coffee served during the maintenance window

The number of holidays observed by the organization during the calendar year, which is rarely the correct choice, regardless of the platform version in use, which is inconsistent with expected behavior, based on standard platform behavior

The number of parking spaces reserved for on-call staff

8 / 10

Which edge design consideration would be most relevant when a customer requires both secure remote-worker mobile client access and PSTN SIP trunk connectivity through IOS XE gateways?

Assuming a single IP phone can serve as the edge device for both requirements

Deploying Expressway-Edge/Core for remote-worker access alongside CUBE for SIP trunk interconnection, each addressing its respective traffic type at the network edge

Assuming no edge device is needed because all traffic will remain purely internal

Disabling PSTN connectivity entirely to simplify the remote-worker access design

Deploying only an internal LAN switch with no edge device to handle either requirement, under normal operating conditions, which does not align with best practices, though this is not generally recommended

Disabling remote-worker access entirely to simplify the PSTN trunk design

9 / 10

Which troubleshooting step would be appropriate if, after a Cisco Unified Communications Manager subscriber node upgrade, phones registered to that node fail to re-register?

Immediately replace every affected phone's hardware as the first troubleshooting step

Verify the node's post-upgrade status, database replication status, and network/service availability before assuming the phones themselves are at fault

Assume registration failures after an upgrade are expected and require no investigation

Assume the issue is unrelated to the upgrade and only check the office lighting

Assume the issue is caused by the phones' physical desk placement

Assume the issue is caused by the phase of the moon

10 / 10

Which statement accurately describes why validating database replication status is an important step both before and after a Cisco Unified Communications Manager cluster upgrade?

Replication status is only relevant on the day the cluster was first installed

Checking replication status is only necessary if the cluster has fewer than two nodes

Replication status is only relevant to voicemail systems and not to call processing clusters, which is inconsistent with expected behavior, which is not the standard approach, which is rarely the correct choice

Replication must be healthy before the upgrade so all nodes have consistent data, and it must be verified healthy afterward to confirm the cluster returned to a fully synchronized state post-upgrade

Replication only needs to be checked once, years before any upgrade is ever planned

Database replication status has no bearing on cluster upgrades and can be safely ignored
