NEW QUESTION # 35
After Mobile and Remote Access is deployed with automatic service discovery, end users encounter the error "Cannot communicate with the server" when they attempt to log in to Cisco Jabber 14.0 using the company email address from within the company network. Which action must an administrator take to resolve this challenge?
Answer: A
Explanation:
When using Cisco Jabber with Mobile and Remote Access (MRA) deployed, the _cisco-uds._tcp SRV record is used to direct clients to the internal Unified Communications (UC) Domain Controller for authentication and directory services. This needs to be present in the internal DNS server to allow Jabber clients to resolve and connect to the required services.
NEW QUESTION # 36
An administrator is configuring a new Cisco Webex Hybrid Message Service deployment, and the Expressway-C Message Connector is successfully registered in the Control Hub. After the server information of the IM and Presence server is added to the Expressway-C, an error "Connectivity to IM and Presence AXL Service could not be established" is displayed in the Control Hub. The Cisco AXL Web Service is enabled on the IM and Presence Service publisher, and the main administrator account enabled for AXL API permission is being used.
Which configuration change must be made to resolve this error?
Answer: D
Explanation:
Configure an account for Message Connector to access the AXL API of the Cisco Unified Communications Manager IM and Presence Service. You must use an independent administrator account, not the main administrator account.

NEW QUESTION # 38
An enterprise is implementing Cisco Webex Hybrid Data Security to control their encryption keys on-premises and comply with data regulations. The deployment requires:
- setting up HDS nodes with proper configuration including certificates and database credentials
- configuring network and proxy settings as per enterprise policy to
connect securely to the Webex cloud
- ensuring redundancy and failover by deploying multiple nodes in a
cluster
Which two actions must the administrator take to configure the hybrid data security deployment?
(Choose two.)
Answer: B,C
Explanation:
Hybrid Data Security nodes are configured using the HDS Setup Tool, which creates the configuration ISO containing required deployment details such as certificates, database credentials, and network settings. Proxy settings must also be configured when the enterprise requires proxy-based internet access so the HDS nodes can securely connect to the Webex cloud.
