Question 1

An administrator is setting up a new call handler in Cisco Unity Connection to serve as an after-hours auto-attendant. The requirement is that this call handler should only be active outside of business hours (9 AM to 5 PM, Monday to Friday). How should the administrator configure Unity Connection to route calls to this new call handler only during the specified off-hours?

Accepted Answer

Define a schedule for business hours and apply it to the main call handler, which then forwards to the after-hours call handler when inactive.

Answer

Configure the call handler's transfer rules to use a schedule that is only active during off-hours.

Answer

Create an 'Alternate Extension' for the main business hours call handler that points to the after-hours call handler.

Answer

In the main business hours call handler, change the 'After Greeting' action to go to the after-hours call handler.

Question 2

A company is deploying Cisco Jabber for Windows to 5000 users via SCCM. The collaboration team wants to pre-configure the client to streamline the user login process and ensure consistency.

Question 3

True or False: In a Cisco IM and Presence high-availability deployment, manual failover of the Presence Redundancy Group is required if the primary server's critical services fail, but the server itself remains reachable on the network.

Accepted Answer

True

Answer

False

Question 4

A healthcare organization needs to implement a secure XMPP federation between their Cisco IM and Presence cluster and a partner hospital's third-party XMPP system. The security policy mandates that all server-to-server communication must be encrypted and mutually authenticated. Which of the following is the most critical component to enable this secure federation?
```mermaid

subgraph Hospital A (Cisco IM&P)
IMP_A[IM&P Server]
end
subgraph Hospital B (3rd Party XMPP)
XMPP_B[XMPP Server]
end
Internet((Internet))
IMP_A -- Encrypted TCP 5269 --> Internet
Internet -- Encrypted TCP 5269 --> XMPP_B
XMPP_B -- Encrypted TCP 5269 --> Internet
Internet -- Encrypted TCP 5269 --> IMP_A
```

Accepted Answer

Exchanging and installing TLS certificates signed by a trusted public Certificate Authority on both XMPP servers.

Answer

Configuring a static route on the IM&P server to the partner's XMPP domain.

Answer

Creating DNS SRV records for `_xmpp-server._tcp` in both organizations' public DNS zones.

Answer

Adding the partner hospital's domain to the 'Allowed' list under XMPP Federation Configuration on the Cisco IM&P server.

Question 5

During a Cisco Jabber deployment, users on the internal corporate network can log in successfully, but users connecting from home via MRA (Mobile and Remote Access) cannot. The MRA deployment is functional for SIP registration and calling. A packet capture on the Expressway-E shows that the client's XMPP connection attempt is being reset. What is the most likely reason for this Jabber login failure over MRA?

Accepted Answer

The IM and Presence domain is not listed in the Expressway-C configuration under 'Domains'.

Answer

The Expressway-C has not been added to the IM&P server's server-to-server authentication allow list (XCP_WHITELIST).

Answer

The public DNS `_collab-edge._tls` SRV record is missing or incorrect.

Answer

The IM and Presence publisher server's certificate is not signed by a public Certificate Authority.

Question 6

A financial institution is using Cisco Unity Connection for voicemail. To comply with regulations, they must prevent users from forwarding voicemails containing sensitive client information outside of their designated department. Which Unity Connection feature should be used to enforce this policy?

Accepted Answer

Configure Restriction Tables to block transfers to numbers outside of the department's extension range.

Answer

Apply a Class of Service that disables message forwarding for all users.

Answer

Create separate partitions for each department and use Search Spaces to limit visibility.

Answer

Use Private Distribution Lists and mark them as 'unaddressable' to other departments.

Question 7

A Cisco Unity Express module integrated with CME is configured with a basic auto-attendant script. Callers report that when they dial the main number, they hear the welcome greeting, but when they enter a valid extension, the call fails. The administrator verifies that the extensions are correctly configured in CME and as mailboxes in CUE. Which is the most likely cause of the issue in the CUE auto-attendant configuration?

Accepted Answer

The 'Call-Redirect' number range is not configured or does not include the user extensions.

Answer

The MWI (Message Waiting Indicator) on/off extensions are not configured on the CUE module.

Answer

The 'dial-by-extension' action in the script is missing the correct dial-peer number for transferring calls to CME.

Answer

The SIP trunk or SCCP integration between CME and CUE is down.

Question 8

A company has two Cisco Unity Connection clusters in different geographic locations, connected via Digital Networking. A user from Site A leaves a message for a user in Site B. Which statement accurately describes how the message and notification are handled?
```mermaid
sequenceDiagram
participant UserA as User A (Site A)
participant CUC_A as Unity Connection (Site A)
participant CUC_B as Unity Connection (Site B)
participant UserB as User B (Site B)

UserA->>CUC_A: Leaves Voicemail for User B
CUC_A->>CUC_B: Replicates Message Body
CUC_B-->>CUC_A: Acknowledges Replication
CUC_B->>UserB: Activates MWI
UserB->>CUC_B: Retrieves Message
```

Accepted Answer

The message is replicated from the Site A cluster to the Site B cluster, where it is stored. The Site B cluster is responsible for activating the MWI for User B.

Answer

The message is stored at Site A, and a notification is sent to Site B. User B's phone connects to the Site A cluster to retrieve the message.

Answer

The message is stored at Site A, and the Site A cluster activates the MWI on User B's phone at Site B via the WAN.

Answer

Only a pointer to the message is sent to Site B. When User B retrieves the message, it is streamed in real-time from the Site A cluster.

Question 9

**Case Study:**

A global consulting firm, 'Innovate Solutions,' is upgrading its collaboration infrastructure. The firm has a primary data center in New York and a disaster recovery (DR) site in London. They have a single CUCM cluster with subscribers in both locations. They are now deploying a new Cisco IM and Presence cluster and require a high-availability solution that can withstand a full data center outage.

**Current Situation:** The CUCM cluster is already configured for geographic redundancy. The IM&P deployment is new. The network link between New York and London has 150ms of round-trip latency. The firm uses persistent chat for project collaboration, which must also be highly available.

**Requirements:**
1. IM&P services must remain active for all users if the New York data center fails.
2. Persistent Chat rooms and history must be preserved and available after a failover.
3. The solution must be officially supported by Cisco.

**Proposed Design:** The lead architect proposes deploying the primary IM&P publisher and a subscriber in New York, and a secondary subscriber in London. All three servers will be part of the same IM&P cluster. The primary Presence Redundancy Group will consist of the New York subscriber (primary) and the London subscriber (secondary).

Which statement identifies a critical flaw in this proposed design?

Accepted Answer

The round-trip latency of 150ms between New York and London exceeds the maximum supported latency for IM&P database replication within a single cluster.

Answer

Persistent Chat services cannot be failed over between data centers.

Answer

The IM&P Publisher must be part of the Presence Redundancy Group for failover to function.

Answer

A single IM&P cluster cannot span multiple CUCM subscriber groups.

Question 10

When troubleshooting Cisco Jabber certificate validation errors, an administrator captures a packet trace and observes that during the TLS handshake, the server presents a certificate, but the Jabber client immediately terminates the connection with a 'Certificate Unknown' alert. The server certificate is valid and signed by the organization's internal Enterprise CA. What is the most likely cause of this issue?

Accepted Answer

The Jabber client's operating system does not have the Enterprise CA's Root certificate in its Trusted Root Certification Authorities store.

Answer

The Common Name (CN) or Subject Alternative Name (SAN) on the server certificate does not match the FQDN the Jabber client is connecting to.

Answer

The server certificate has expired.

Answer

The server is not sending the full certificate chain (intermediate and root certificates) during the TLS handshake.
