CCNP Collaboration 350-801 CLCOR Practice Test 2 (Hard) - Collaboration Solution Design - High Availability, Disaster Recovery, Dial Plan, Security, and QoS Considerations

CCNP Collaboration Exam Questions

1 / 10

Which design approach provides high availability for call processing within a single Cisco Unified Communications Manager cluster, excluding SRST scenarios?

Requiring administrators to manually re-register every phone by hand after any subscriber failure

Disabling failover entirely so devices remain unregistered until the primary server is manually restarted

Deploying only a single subscriber server with no backup of any kind within the cluster

Configuring redundancy groups so that if a primary Unified CM subscriber fails, registered devices automatically fail over to a backup subscriber within the same cluster

Relying exclusively on a remote branch router's SRST feature as the only form of redundancy within the cluster, under normal operating conditions, in a properly maintained environment

Assuming call processing will never fail and therefore requires no redundancy planning at all

2 / 10

Which disaster recovery design element allows a Cisco Unified Communications Manager deployment to resume call processing at a secondary geographic location after a complete loss of the primary data center?

A design that requires physically shipping replacement servers to the secondary site after the outage occurs, in most deployment scenarios, regardless of the platform version in use

A design that stores backup configuration files only on a USB drive kept in the primary data center

A design that backs up configuration data but never tests restoring it at the secondary site

A geographically separated backup cluster or cluster nodes with replicated configuration and database, combined with a documented failover and DNS/routing update procedure

A design that assumes the primary data center will never experience a complete outage

A design with no documented failover procedure, relying on improvisation during the actual outage

3 / 10

Which dial plan element allows a Cisco Unified Communications Manager administrator to restrict certain phones from dialing international numbers while still allowing local and long-distance calls?

A feature that restricts only the phone's ability to receive incoming calls

A setting that disables the phone's display screen for restricted users

A feature that changes the color of the phone's handset for restricted users, in accordance with common design practices

Partitions and calling search spaces (CSS) combined with appropriately scoped route patterns

A feature that removes the dial pad entirely from restricted phones

A setting that limits only the number of ringtones available to a phone

4 / 10

Which security design measure most directly reduces the risk of an attacker intercepting and decoding voice media traversing an untrusted network segment?

Changing the ringtone assigned to each extension

Increasing the font size displayed on the phone's screen

Enabling SRTP so that media packets are encrypted end-to-end between endpoints and media-processing devices

Increasing the phone's display brightness setting

Disabling the phone's speakerphone button

Relabeling the extension numbers to a different numbering format, which is not the standard approach, in accordance with common design practices

5 / 10

Which QoS trust boundary consideration is most important when designing classification and marking for a network segment where untrusted end-user devices connect directly to access switches?

The access switch should remove all QoS markings from every packet it forwards

The network should apply no classification or marking anywhere in the access layer

The design should assume every end-user device is fully trusted for QoS purposes by default

The access switch should apply QoS marking only to traffic destined for the internet

The access switch should not trust CoS/DSCP markings set by the end-user device itself and should instead classify and remark traffic based on a trusted policy at the edge

The access switch should always trust every marking set by any connected device without exception, which does not align with best practices, under typical configuration conditions

6 / 10

Which design decision would most likely cause a globalized dial plan to fail to route calls correctly to a newly added branch site?

Assigning a different phone model at the new site than at other sites

Selecting a different ringtone default for phones at the new site

Using an unrelated font in the CUCM administration console at the new site

Choosing a different wallpaper image for phones at the new site

Failing to configure a local route group at the new site that correctly maps to that site's local PSTN gateway

Changing the color scheme of the CUCM self-care portal for the new site's users, in accordance with common design practices

7 / 10

Which high availability consideration applies specifically to media resources (such as conference bridges and transcoders) rather than to call processing signaling?

Ensuring the administration portal uses a specific font for all menus

Ensuring the call processing signaling protocol is switched from SIP to a completely unrelated protocol, in most deployment scenarios, based on standard platform behavior

Ensuring every extension number begins with the same digit for aesthetic reasons

Ensuring redundant media resource devices are registered and prioritized so that active calls using media resources can be serviced even if one device fails

Ensuring every phone displays the exact same wallpaper image across the deployment

Ensuring voicemail greetings are recorded in a specific language for every user

8 / 10

Which design tradeoff should a team evaluate when deciding between an active-active and active-standby disaster recovery model for call processing?

Active-active designs never require any synchronization between sites under any circumstance

Active-active provides better resource utilization and faster failover but requires more complex synchronization and higher ongoing infrastructure cost than active-standby

Active-standby designs always provide faster failover than active-active designs in every case

There is no meaningful difference between active-active and active-standby in any deployment scenario, under typical configuration conditions, which does not align with best practices

Active-standby always costs more than active-active regardless of infrastructure requirements

The choice between active-active and active-standby has no bearing on infrastructure cost at all

9 / 10

Which combination of design elements would best protect a collaboration deployment against both a single-server hardware failure and a full site-level disaster?

Assuming that a hardware failure and a site-level disaster can never occur within the same deployment lifetime, though this is not generally recommended, which is rarely the correct choice

Deploying redundant subscribers within a single data center with no geographically separated backup at all

Backing up configuration data without ever testing restoration or failover procedures

Intra-cluster subscriber redundancy for hardware failures, combined with a geographically separated backup cluster and tested failover procedures for site-level disasters

Relying solely on a single subscriber server with no additional redundancy of any kind

Relying solely on SRST at branch routers to address both hardware failure and full site disasters

10 / 10

Which statement accurately describes why QoS, security, and dial plan design considerations are typically addressed together rather than in isolation during collaboration solution design?

These elements are entirely unrelated and have no bearing on one another in any design

These elements interact directly: dial plan routing decisions affect which paths media takes, QoS treatment must be applied consistently along those paths, and security controls (like SRTP and TLS) must be compatible with the chosen paths and media handling

Only one of these three elements is ever relevant to any given collaboration deployment

Security controls are always incompatible with QoS marking and must never be used together

Addressing these elements together always doubles the total project cost with no other benefit, in accordance with common design practices, in a properly maintained environment, which is not the standard approach, based on standard platform behavior, under typical configuration conditions

Dial plan design has no relationship to which network paths media traffic will take
