An incoming off-net call to a user fails. An engineer notices that the off-net call is G.711, but the phone accepts only G.729. Which media resource on a Cisco Unified Border Element and Cisco Unified Communications Manager must the engineer configure to manage the codec negotiation?
Answer: A
Media Termination Points can only handle G.711. They can't handle G.729. An MTP is mostly for providing supplementary services like hold, transfer, etc. They can also allow connection between a SIP device that requires Early offer and one that requires delayed offer. The MTP transcoding capability is limited to a to u law and packet size. From Cisco.com "The MTP accepts two full duplex G.711 Coder-Decoder (CODEC) stream connections. MTPs bridge the media streams between two connections. The streaming data received from the input stream on one connection is passed to the output stream on the other connection, and vice versa. In addition, the MTP trancodes A-law to Mu-law (and vice versa) and adjusts packet sizes as required by the two connections." https://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/3_1_2/ccmsys/a05mtp.html

DRAG DROP - Drag and drop the SNMPv3 message types from the left onto the corresponding definitions on the right. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
Difference between Inform and Trap : "Traps are identical to version 2 traps and are unacknowledged notifications sent by agents to managers. Informs are acknowledged notifications. Agent sends an inform notification and waits for acknowledgment." https://snmpsharpnet.com/index.php/snmp-version-3-notifications-traps-and-informs/

A collaboration engineer configures Cisco UCM to act as a DHCP server. What must be done next to configure the DHCP server?
Answer: B
What are two features of Cisco Expressway that the customer gets if Expressway-׀¡ and Expressway-E are deployed? (Choose two.)
Answer: AB
Cisco Expressway is designed specifically for comprehensive collaboration services. It features established firewall-traversal technology and helps redefine traditional enterprise collaboration boundaries, supporting Cisco’s vision of any-to-any collaboration. As its primary features and benefits, Cisco Expressway offers proven and highly secure firewall-traversal technology to extend an organization’s reach. It helps enable business-to-business, business-to- consumer, and business-to-cloud-service-provider connections. It provides session-based access to comprehensive collaboration for remote workers, without the need for a separate Virtual Private Network (VPN) client.

A collaboration engineer needs to replace the original, single NTP server that was configured during the initial install of a Cisco UCM server. What is the first step to accomplish this task?
Answer: D
I am not agree with ciscogeek's answer, and the correct answer is D. If you look at the exhibit on the "utils ntp status", it shows two original servers installed. And if you ready the question carefully, there is a "," after "original,", which means, from two original NTP servers, only single NTP server needs to be delete. So you can delete a single NTP server from the two listed NTP servers. However, even if there is only one server, you can’t enable authentication for the new NTP server, you need first add it, then enable it with command “utils ntp auth symmetric-key enable” which you get prompt to select for enable the authentication for the listed servers: admin:utils ntp auth symmetric-key enable At the end, nothing in the question mentioned about NTP authentication, as you can see authentication report with the following command: admin:utils ntp auth symmetric-key status

A collaboration engineer adds a redundant NTP server to an existing Cisco Collaboration solution. On the Cisco UCM OS Administration page, the new NTP server shows as `Not Accessible`. Which action resolves this issue?
Answer: B
It appears the service isn't running on the second NTP server. I would validate that the service is running. If it's not running, Start the service. If it is running, there's likely an issue with the service running. Proceed by restarting the service

Which action is required for a firewall configuration on a Mobile and Remote Access through Cisco Expressway deployment?
Answer: A
Guide says exactly the same: The external firewall must allow the following inbound connections to Expressway: SIP: TCP 5061; HTTPS: TCP 8443; XMPP: TCP 5222; Media: UDP 36002 to 59999. https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/expressway/config_guide/X14-2/mra/exwy_b_mra-deployment-guide-x142/exwy_m_requirements-for-mra.html

The IP phones at a customer site do not pick an IP address from the DHCP. An engineer must temporarily disable LLDP on all ports of the switch to leave only CDP. Which two commands accomplish this task? (Choose two.)
Answer: BD
The answers are correct on how you'd disable LLDP, but what kind of question is this? Why would you even need to disable LLDP when CDP is the first protocol the phones will use.. I have myriads of active deployments where both CDP and LLDP are enabled on the switches. The phones ALWAYS use CDP unless CDP is disabled from the phone's configuration or if the switch doesn't support CDP. Power and VLAN configurations are negotiated by CDP if CDP is available. If it's not, LLDP will STILL work! So why is there a need to disable it? Because it's not proprietary to Cisco? So what?
