CLCOR ON Premises Call Control Practice Test 2 — 15 Questions

Question 1

You are troubleshooting a scenario where internal calls between two offices are using the G.711 codec, but you want them to use G.729 to save bandwidth. Where should you change the codec setting?

Accepted Answer

System > Region Information > Region. The codec used between two devices is determined by the Region setting. You must update the Region matrix to specify G.729 between the two regions.

Answer

Device > Device Settings > Common Device Configuration

Answer

System > Device Pool

Answer

System > Location

Question 2

When designing a redundant CUCM deployment, which mechanism ensures that if a primary subscriber fails, phones automatically register to a secondary subscriber?

Accepted Answer

CM Group. The Cisco Unified Communications Manager Group (CM Group) defines the ordered list of CUCM servers that a device will attempt to register with.

Answer

SIP Trunk Security Profile

Answer

Route List

Answer

Device Pool

Question 3

You need to prevent certain internal users from making international calls while allowing them to dial local numbers. What is the most efficient way to implement this in CUCM?

Accepted Answer

Assign a CSS to the device that includes a Partition containing local routes but excludes a Partition containing international routes.. Partitioning and Calling Search Spaces (CSS) are the standard mechanisms in CUCM to restrict dialing privileges based on the source of the call.

Answer

Use an Application Dial Rule.

Answer

Modify the device pool's location.

Answer

Configure a Route Filter on the Route Pattern.

Question 4

Which component in CUCM is responsible for providing the necessary resources for conference calls, such as hardware or software-based conference bridges?

Accepted Answer

Media Resource Group. Media Resource Groups (MRG) collect media resources like conference bridges, and MRG lists (MRGL) determine which resources are available to specific devices.

Answer

Region

Answer

Route Group

Answer

Device Pool

Question 5

If a Translation Pattern is configured in CUCM, at what stage of the call processing does the digit manipulation occur?

Accepted Answer

Before the Route Pattern is matched.. Translation Patterns act as a mid-call processing step. When a digit string is dialed, CUCM checks for Translation Patterns before checking Route Patterns.

Answer

After the call is sent to the gateway.

Answer

At the device level during registration.

Answer

Only when the call fails to route.

Question 6

Which field in a Route Pattern determines how CUCM processes a call when a user dials a number that matches the pattern?

Accepted Answer

Gateway/Route List. The 'Route Option' and 'Route Partition' fields work together, but the 'Gateway/Route List' field specifically tells CUCM where to send the call once the pattern is matched.

Answer

Calling Search Space

Answer

Route Filter

Answer

Translation Pattern

Question 7

You are implementing a centralized dial plan. You have multiple sites, each with local PSTN gateways. How can you ensure that an emergency call from a specific site is always routed to the local PSTN gateway of that site?

Accepted Answer

Use site-specific partitions and assign the local gateway to a CSS that includes that partition.. By using a combination of Partitions and CSS, you can ensure that the emergency route pattern is reachable by all, but the specific route pattern matches the local gateway's partition.

Answer

Use Transformation Masks on the device.

Answer

Configure the location in the device pool to match the site.

Answer

Create a separate CUCM cluster for each site.

Question 8

Which feature allows you to group multiple gateways and route lists to provide load balancing and failover for outbound calls?

Accepted Answer

Route List. Route Groups contain a list of gateways, and Route Lists contain an ordered list of Route Groups to provide logical routing paths.

Answer

Route Pattern

Answer

Translation Pattern

Answer

Device Pool

Question 9

In CUCM, what is the purpose of the 'Calling Search Space' (CSS)?

Accepted Answer

To define which partitions a device can access.. The CSS is a list of partitions that a device or line can access to search for dialable patterns.

Answer

To define the codec used for calls.

Answer

To define the physical location of the device.

Answer

To define the bandwidth limit of a call.

Question 10

You are configuring a SIP trunk between CUCM and a CUBE. Which setting is critical to ensure that the SIP signaling is encrypted?

Accepted Answer

SIP Trunk Security Profile. A SIP Trunk Security Profile is where you define the security mode (Authenticated or Encrypted) for the trunk.

Answer

Enterprise Parameters

Answer

Device Pool

Answer

SIP Profile

Question 11

Where do you configure the time zone for a specific set of devices, such as those in a specific branch office?

Accepted Answer

Date/Time Group. The Date/Time Group is assigned to the Device Pool, which in turn is assigned to the device to set the local time.

Answer

Region

Answer

Enterprise Parameters

Answer

Location

Question 12

A user complains that they cannot see the 'Transfer' softkey on their phone during an active call. Where is the most appropriate place to check the softkey configuration?

Accepted Answer

Device > Device Settings > Softkey Template. Softkey Templates are assigned to devices (or device pools) to define which buttons appear during various call states.

Answer

System > Enterprise Phone Configuration

Answer

Device > Device Pool

Answer

Device > Phone

Question 13

When a call is made to a destination that matches multiple partitions in a user's CSS, how does CUCM determine which pattern to use?

Accepted Answer

Longest match rule.. CUCM selects the most specific match first. If multiple patterns are equally specific, it uses the first one found in the search space order.

Answer

The pattern configured first.

Answer

Random selection.

Answer

The pattern with the lowest partition index.

Question 14

You are integrating an external voicemail system with CUCM. Which object is used to define the dialable number that users call to reach their voicemail box?

Accepted Answer

Voicemail Pilot. A Voicemail Pilot is the directory number that acts as the entry point to the voicemail application.

Answer

Voicemail Profile

Answer

Route Pattern

Answer

Translation Pattern

Question 15

You are migrating a legacy PBX to CUCM. You need to normalize incoming caller IDs from the PSTN to E.164 format. Which tool is best suited for this at the gateway level?

Accepted Answer

Calling Party Transformation Pattern. Calling Party Transformation Patterns are specifically designed to normalize incoming caller IDs at the CUCM level before they reach the endpoint.

Answer

Translation Pattern

Answer

Route Filter

Answer

Route Pattern
