Question 1:
Refer to the exhibit.
An administrator must fix the SRV records to ensure that server 1 .sample.com is always contacted first from the three servers. Which solution should the engineer apply to resolve this issue?
A. Priority = 100. Weight = 90
B. Priority = 5. Weight = 70
C. Priority = 10, Weight = 5

Question 3:
Which option must be used when configuring the Local Gateway for a Cisco Webex Calling trunk?
A. local authentication
B. certificate-based
C. mutual TLS
D. Auth-based
Correct Answer: B
A certificate-based trunk is a type of trunk that uses certificates to authenticate the connection between Webex Calling and the Local Gateway
1.
A Local Gateway is a supported session border controller that terminates the trunk on the premises
2.
A certificate-based trunk requires a certificate authority (CA) to issue and manage the certificates for both Webex Calling and the Local Gateway

Question 5:
What are two Cisco UCM location bandwidths that are deducted when G.729 and G.711 codecs are used? (Choose two.)
A. If a call uses G.729, Cisco UCM subtracts 16k
B. If a call uses G.711, Cisco UCM subtracts 80k
C. If a call uses G.729, Cisco UCM subtracts 24k
D. If a call uses G.711, Cisco UCM subtracts 64k
E. If a call uses G.729, Cisco UCM subtracts 40k
Correct Answer: BC
After the call is established, the Cisco Unified Communications Manager will subtract bandwidth from the locations, depending on the codec that is used in that call. If the call is using G.711, Cisco Unified Communications Manager subtracts
80k. If the call is using G.723, Cisco Unified Communications Manager subtracts 24k. If the call is using G.729, Cisco Unified Communications Manager subtracts 24k.

Question 8:
Which action is required for a firewall configuration on a Mobile and Remote Access through Cisco Expressway deployment?
A. The external firewall must allow these inbound connections to Expressway: SIP: TCP 5061: HTTPS: TCP 8443; XMPP: TCP 5222; Media: UDP 36002 to 59999.
B. The internal firewall must allow these inbound and outbound connections between Expressway- and Expressway-E: SIP: HTTPS (tunneled over SSH between and E): TCP 2222: TCP 7001; Traversal Media: UDP 2776 to 2777 (or 36000 to 36011 for large VM/appliance); XMPP: TCP 7400.
C. Do not use a shared address for Expressway-E and Expressway-, as the firewall cannot distinguish between them. If static NAT for IP addressing on Expressway-E is used, ensure that any NAT operation on Expressway- does not resolve the same traffic IP address. Shared NAT is not supported.
D. The traversal zone on Expressway- points to Expressway-E through the peer address field on the traversal zone, which specifies the Expressway-E server address. For dual NIC deployments, set the Expressway-E address using an FQDN that resolves the IP address of the internal interface.
Correct Answer: A

Question 15:
After an engineer runs the utils ntp status command on the Cisco Unified Communications Manager publisher, the stratum value is 16. Which issue can the Cisco Unified CM cluster experience?
A. Unified CM sends an NTPV4 packet.
B. Database replication is not synchronized on the Unified CM nodes.
C. The cluster loses access to port 124 at the firewall.
D. The date/time group on all phones defaults to the time zone of the engineer.
Correct Answer: B
16 is a invalid stratum value that means “this server is not considered a time provider”. The stratum can be invalid for various reasons, the most common of which is that the “time provider not synchronized”, the “configured source does not exist”, or the “ntp server not running”. CUCM can communicate with the NTP server on Port 123
