Which troubleshooting tool does an engineer use to determine whether a cat! is being subjected to traversal bandwidth restrictions?
Correct Answer: B
= A calls log is a tool that records the details of each call that passes through the Expressway, including the source and destination addresses, the protocol, the call duration, the bandwidth, and the reason for termination. An engineer can use the calls log to check the bandwidth allocation and usage for each call, and to identify any calls that were rejected or downspeeded due to traversal bandwidth restrictions. To access the calls log, go to Status > Calls > History on the Expressway web interface. The calls log can also be exported as a CSV file for further analysis.

Question 62
As engineer notices that TMS Conference Control Center is not displaying the interface on a scheduler's computer, but it operates properly on the administrator's computer. Which cause is the most likely?
Correct Answer: A
Question 63
Which statement about Call Service Connect on a Cisco Spark Hybrid deployment is true?
Correct Answer: D
= Call Service Connect is a hybrid service that allows integration between Cisco Spark and Cisco Unified Communications Manager (CUCM). Call Service Connect enables the Cisco Spark app to be used as a softphone for voice and video calling, and to share an extension with the CUCM desk phone. Call Service Connect also provides a unified call history and caller ID across Cisco Spark and CUCM devices123 Call Service Connect requires media traversal capabilities and licenses to be installed on the Expressway-C and Expressway-E pair that connects the CUCM and the Cisco Collaboration Cloud. Call Service Connect also requires mutual TLS (mTLS) authentication between the Expressway-E and the cloud, and between the Expressway-C and the CUCM. Call Service Connect depends on Call Service Aware, which is another hybrid service that synchronizes the user and device information from the CUCM to the cloud. Call Service Aware must be deployed before Call Service Connect124 References := 1Cisco Spark Hybrid Services Data Sheet 2Cisco Spark Hybrid Services Deployment Guide 3Cisco Spark Hybrid Services At-a-Glance 4Deployment guide for Hybrid Calling for Webex Devices (Device Connector)

Question 65
Which tool does an engineer use to collect information on system activity, including TCP dumps, of the Conductor over a period of time?
Correct Answer: A
* The Cisco TelePresence Conductor is a conference resource manager that orchestrates and allocates conference bridges and media resources for scheduled and ad hoc conferences1. * To collect information on system activity, including TCP dumps, of the Conductor over a period of time, an engineer can use the diagnostic logging feature of the Conductor2. Diagnostic logging allows the engineer to capture detailed logs and network traces for troubleshooting and analysis2. * To enable diagnostic logging, the engineer can go to the web interface of the Conductor and navigate to Maintenance > Diagnostics > Diagnostic Logging2. The engineer can then select the components and levels of logging, the duration and frequency of logging, and the destination of the log files2. * The other options are incorrect because: * Status log is a feature of the Conductor that shows the current status of the system, such as the CPU and memory usage, the software version, the license information, and the network configuration3. It does not provide historical or detailed information on system activity or TCP dumps. * Network log is a feature of the Conductor that shows the network events and errors that occurred on the system, such as SIP messages, DNS queries, and NTP synchronization. It does not provide TCP dumps or allow the engineer to specify the components and levels of logging. * CDR records are call detail records that show the information about the calls that were made or received through the Conductor, such as the call ID, the conference name, the participants, the duration, and the quality. They do not provide information on system activity or TCP dumps.
