700-038 Sample Questions & Answers

Registration (SIP) and presence (XMPP) use specific TCP ports that are likely open, allowing the client to connect. However, audio/video calls use a range of UDP ports for the RTP media stream. If these ports are blocked by a firewall, the signaling will succeed, but the media will fail, resulting in no audio or video. An incorrect SRV record would prevent initial discovery and registration. A down IM&P service would affect presence for all users, not just MRA.

This block details all the costs incurred to operate the business model. The analyst would show how Webex reduces costs (e.g., travel, real estate, legacy system maintenance).

This block represents the cash a company generates. The analyst can argue that improved collaboration via Webex leads to faster sales cycles, better customer retention, or new service offerings, thus increasing revenue.

Webex Desk series devices (like the Desk Mini or Desk Hub) registered to the Webex cloud can be configured in Kiosk mode. This provides a simplified, locked-down user interface ideal for public use. The cloud registration model simplifies large-scale management and deployment without requiring on-premises infrastructure at each store, making it cost-effective and scalable for a retail environment.

The utils diagnose test command runs a series of checks on the appliance to validate the health of the system. It verifies DNS resolution, NTP synchronization, database health, disk space, and other critical system components without causing a service interruption. It is a fundamental first step in troubleshooting general CUCM issues.

Search Rules and Transforms are the core components in Expressway for policy-based call routing and URI manipulation. For B2B calls, an engineer would create Search Rules to match incoming calls from specific external domains (e.g., @partner-research.org), apply Transforms to rewrite the URI if needed, and route the call to the appropriate internal zone. This mechanism is essential for securely enabling interoperability with trusted external organizations while blocking unwanted traffic. Traversal Zones define the link between Expressway-C and E, but they don't handle the URI logic. CPL is not a primary feature for this task.

The configuration validation process in CCW is a rule-based engine that checks the BOM for technical accuracy. It verifies that required software is selected for hardware (e.g., phone licenses for CUCM), that power cords and other necessary accessories are included, and that the combination of products is a supported configuration. This helps prevent ordering incomplete or incompatible solutions.

The Service Provider (Cisco UCM/Webex) needs the IdP's public certificate to verify the signature on the SAML assertions it receives.

The IdP (Azure AD) needs the SP's metadata, which contains information like the Assertion Consumer Service (ACS) URL and the SP's entity ID.

The SP (Cisco UCM/Webex) needs the IdP's metadata, which contains the SSO login URL and the IdP's entity ID.

CFOs are primarily concerned with financial metrics. A TCO analysis shifts the focus from the initial purchase price (CapEx) to the long-term savings (lower OpEx) from reduced travel, lower maintenance costs, and increased productivity. Demonstrating a clear ROI provides a compelling financial reason to approve the expenditure. Technical features are less persuasive to a financial stakeholder than a solid business case.

A CSSM satellite is an on-premises server that acts as a local proxy for Cisco Smart Licensing. Internal devices like CUCM register and report consumption to the satellite. The satellite then periodically synchronizes this information with the main Cisco Smart Software Manager portal in the cloud. This is ideal for organizations with security policies that restrict direct internet access from internal servers.

This statement is false. Cisco's best practice and recommended deployment model for Expressway-E is to use a single network interface. All traffic, both from the public internet and towards the internal Expressway-C, traverses this single interface. A second NIC is not required and can complicate routing and NAT configurations.
