• Question 3:

  A Cisco voice gateway is configured to use a sip-kpml DTMF relay in global settings. A new SIP dial peer is configured for a third-party application that only supports an in-band DTMF relay. Which commands must an engineer run on the dial peer?

  A. dtmf-relay sip-info

  B. dtmf-relay sip-notify

  C. dtmf-relay rtp-net

  D. no dtmf-relay sip-kpml

  Correct Answer: C

• Question 4:

  Which Cisco lM and Presence service handles failover and state changes in the cluster?

  A. XCP Sync Agent

  B. Cisco Server Recovery Manager

  C. Cisco XCP Connection Manager

  D. XCP router

  Correct Answer: B

• Question 5:

  SIP proxies have operations defined in RFC 3261 and supporting extensions. Though no lETF RFC completely defines how SBCs must function. SBCs evolved over the years. Which two operations demonstrate the high-level differences between SBCs and SIP proxies? (Choose two.)

  A. Stateful proxies are context-aware and can terminate communication sessions by themselves

  B. SlP proxies add a Via header and optionally a Record-Route header, and the rest of the headers are left untouched

  C. SBCs can modify headers such as To, From, Contact, and Call-D.lt can introduce new headers into the SIP message

  D. SBCs are capable of interworking completely different protocols to set up, modify, and tear down communication sessions. It includes SIP, H.323,and MGCP protocols

  E. SIP proxies are SDP-aware and can change the SDP bodies

  Correct Answer: BD

• Question 6:

  An engineer is deploying the Webex app on a Microsoft Windows computer that has multiple user accounts. Which CLI argument allows the engineer to Install the application as a "per machine" Installation?

  A. ACCEPT_EULA

  B. INSTALL ROOT

  C. ALLUSERS

  D. FORCELOCKDOVN

  Correct Answer: C

  The ALLUSERS property is a command-line argument that can be used to install the Webex app as a "per machine" installation. This means that the app will be installed for all users on the computer, regardless of which user account is currently logged in. The ACCEPT_EULA property is a command-line argument that can be used to accept the end-user license agreement (EULA) for the Webex app. The INSTALL_ROOT property is a command-line argument that can be used to specify the installation directory for the Webex app. The FORCELOCKDOWN property is a command-line argument that can be used to prevent users from uninstalling the Webex app.

• Question 7:

  Which two parameters influence the total number of supported conference participants on a Cisco IOS XE router that has DSP modules? (Choose two.)

  A. voice codec

  B. session capacity of the PVDM module

  C. number of protocol data units

  D. software version Of the router

  E. license types

  Correct Answer: AB

  These are two parameters that influence the total number of supported conference participants on a Cisco IOS XE router that has DSP modules. A voice codec is a software algorithm that compresses and decompresses voice signals for transmission over a network. Different voice codecs have different bandwidth requirements and quality levels. A PVDM module is a hardware component that provides digital signal processing (DSP) resources for voice applications such as conferencing and transcoding. A PVDM module has a fixed session capacity, which is the maximum number of voice channels that it can support simultaneously.

• Question 8:

  What is the default TCP port for SIP OAuth mode in Cisco UCM?

  A. 5011

  B. 3174

  C. 8443

  D. 5090

  Correct Answer: D

  The Cisco Unified Communications Manager (CUCM) uses SIP Phone OAuth Port (5090) to listen for SIP line registration from Jabber OnPremise devices over TLS. However, CUCM uses SIP Mobile Remote Access Port (default 5091) to listen for SIP line registrations from Jabber over Expressway through mTLS. Both of these ports are configurable.

• Question 9:

  An engineer is configuring a phone system CISCO UCM and wants to activate TFTP service. The engineer selects the serviceability page for configuration. Which nodes configurable for TFTP?

  A. any two nodes

  B. any node

  C. only nodes that have Cisco UCM service enabled

  D. any subscriber nodes

  Correct Answer: C

  TFTP is a network protocol that is used to transfer files between devices. It is often used to transfer firmware and configuration files to network devices. In order to use TFTP, the device must have a TFTP server configured. In Cisco UCM, the TFTP server is configured on the serviceability page. The TFTP server can be configured on any node that has Cisco UCM service enabled. The TFTP server cannot be configured on nodes that do not have Cisco UCM service enabled.

• Question 10:

  What are two access management mechanisms in Cisco Webex Control Hub? (Choose two.)

  A. multifactor authentication

  B. Active Directory synchronization

  C. attribute-based access control

  D. single sign-on with Google

  E. Client ID/Client Secret

  Correct Answer: AB

  The two access management mechanisms in Cisco Webex Control Hub are multifactor authentication and Active Directory synchronization. Multifactor authentication is a security measure that requires users to provide two or more pieces of evidence to verify their identity. This can include something they know, such as a password, and something they have, such as a security token. Active Directory synchronization is a process that allows Cisco Webex Control Hub to automatically synchronize user accounts from an Active Directory domain. This can simplify user management and provide users with single sign-on access to Cisco Webex Control Hub and other applications.
