700-038 Advanced Collaboration Architecture Field Engineer Practice Questions

A hospital is upgrading its collaboration infrastructure. A key requirement is to allow physicians to use their personal mobile devices (BYOD) for clinical communication via Cisco Jabber, both on-site over Wi-Fi and remotely. The hospital's compliance officer insists that all Jabber voice and video traffic from these mobile devices must be encrypted to comply with HIPAA. Which technology is essential to meet this requirement?

When deploying a virtualized Cisco Unified Communications Manager, the administrator must choose an OVA template that matches the expected user and device count. What is the primary reason for strictly adhering to the specifications defined in the Cisco-provided OVA files?

Case Study

A mid-sized manufacturing company with 1,500 employees is planning a collaboration infrastructure refresh. They currently have an end-of-life Cisco Unified Communications Manager Business Edition 6000 (BE6K) solution. The IT director wants to move to a more scalable and resilient platform. The company has two data centers for redundancy and is considering a mix of on-premises and cloud services.

The key technical requirements are: 1) High availability for call control, with automatic failover in less than one minute. 2) Centralized voicemail and IM/presence services. 3) A clear migration path from their existing user licenses. 4) The ability to integrate cloud-based Webex Meetings for all users. 5) The design must follow a well-documented, tested, and supported Cisco architecture to minimize deployment risk.

A field engineer is tasked with proposing a new architecture and creating a high-level Bill of Materials (BOM). The solution must be on-premises for core call control per the customer's data sovereignty policy but leverage the cloud for meetings.

Given these requirements, which Cisco architecture and licensing model should the engineer propose?

A network engineer observes that after a recent security audit, Cisco Jabber users can no longer download their call history or access visual voicemail. Other functions like making calls and presence are working correctly. The audit involved tightening firewall rules between the user VLAN and the data center VLAN where the Cisco Unity Connection server resides. Which protocol is most likely being blocked, causing this specific issue?

A systems administrator is analyzing a call flow diagram to troubleshoot an issue with Webex Hybrid Calendar Service. The goal is to understand how a meeting scheduled in an on-premises Microsoft Exchange server gets populated in the Webex cloud. What is the role of the Expressway-C Calendar Connector in this process?

A financial services firm is deploying a new Cisco Collaboration solution and must ensure all media streams between internal endpoints and the PSTN gateway are encrypted. The security team has mandated that the solution must not introduce significant processing overhead on the Cisco Unified Communications Manager (CUCM) publisher. Which configuration approach meets these requirements?

A university is migrating its legacy Nortel PBX to a centralized Cisco UCM cluster hosted in a primary data center. The university has three remote campuses connected via MPLS links with varying bandwidth. To ensure call survivability during a WAN outage at a remote campus, which two components are essential to deploy at each remote site? (Select TWO)

A field engineer is planning the virtualization of a Cisco Unity Connection cluster on a customer's existing VMware ESXi infrastructure, which was not purchased through Cisco. The customer wants to ensure they receive full Cisco TAC support for the Unity Connection application. Which deployment model must the engineer follow?

Case Study

A multinational corporation with headquarters in New York and major offices in London and Tokyo is consolidating its disparate, aging PBX systems into a single global Cisco collaboration solution. The primary business drivers are to reduce international calling costs, streamline dial plan management, and provide seamless collaboration features (IM, presence, video) to all 10,000 users. The company has a robust MPLS network connecting the three sites, but bandwidth is provisioned based on existing data needs and is a significant cost concern.

The project architect has proposed a single, centralized CUCM cluster in the New York data center to serve all users globally. Each major office will have a local gateway for PSTN access. The key requirements from the stakeholders are: 1) Calls between any two corporate sites must stay on the corporate WAN. 2) The solution must be resilient to inter-site WAN failures. 3) The global dial plan must be simplified, allowing users to dial a short extension to reach anyone in the company. 4) Bandwidth consumption for voice and video calls over the WAN must be strictly controlled.

To address these requirements, the architect plans to use specific CUCM features to manage call routing and bandwidth. They need to ensure that calls originating in London and destined for the London PSTN are routed through the local London gateway, and not hairpin across the WAN to the New York gateway. Similarly, bandwidth for video calls between New York and Tokyo needs to be managed to prevent network congestion.

Which CUCM feature is most critical for implementing the globalized, location-aware call routing and simplified dial plan?

True or False: When creating a Bill of Materials (BOM) based on a Cisco Validated Design (CVD) for Collaboration, a field engineer must include every single Product ID (PID) listed in the CVD's sample BOM without modification to ensure design validity.
