NEW QUESTION # 10
While provisioning conference rooms on the SMC, users can switch between organization management and area management when a specified item is not present beneath the root node.
Which option is it?
Answer: B
Explanation:
Huawei SMC supports two approaches to organizing conference rooms: organization-based management and area-based management. The selected model determines how conference rooms are structured and which conference users can access them.
In organization-based management, conference rooms belong to organizational structures. Their visibility is generally limited to users associated with the corresponding organization and its permitted hierarchical relationships.
In area-based management, conference rooms are organized geographically or administratively and are available as shared conference-room resources across the system.
Option B is the likely intended answer because it identifies both types of objects that could prevent a clean transition between the management structures: subordinate nodes and provisioned conference rooms. A transition involving an empty root structure avoids complications associated with existing hierarchical assignments and conference-room associations.
Option A considers only subordinate nodes, while option D considers only conference rooms. Option C concerns conference users rather than the complete conference-room management hierarchy.
Verification concern: Huawei Training Material, Organization and Area (1) and (2), confirms that the management modes can be switched. However, the supplied materials do not explicitly specify that both subordinate nodes and conference rooms must be absent beneath the root node before switching. Therefore, option B is a technically plausible interpretation, not a conclusively documented answer.

Choose three
Answer: A,B,D
NEW QUESTION # 12
The INVITE transaction uses a three-way handshake process, and if the request fails to return, the ACK belongs to a different transaction.
Answer: B
Explanation:
Huawei's SIP transaction model distinguishes INVITE transactions from non-INVITE transactions. The INVITE transaction uses a three-way signaling procedure involving an INVITE request, a final response, and an acknowledgment.
The relationship between the ACK and the original INVITE transaction depends on the final response.
When the INVITE receives a successful 2xx response, such as 200 OK, the subsequent ACK is treated independently from the original INVITE transaction. This allows the acknowledgment to follow the successful session-establishment procedure.
When the INVITE receives an unsuccessful final response, such as 486 Busy Here, the ACK remains part of the original INVITE transaction. Its purpose is to acknowledge the unsuccessful final response and complete transaction processing.
The statement incorrectly claims that the ACK belongs to a different transaction when the request fails. This reverses the distinction defined in the Huawei Training Material.
Therefore, option B is correct.
Huawei explicitly states that, when a request fails to be returned, the ACK is part of the INVITE transaction.
Its accompanying signaling diagrams distinguish the successful INVITE procedure from the unsuccessful procedure.
The examination tests the candidate's understanding of transaction boundaries, particularly the difference between acknowledgments of successful and unsuccessful INVITE responses.

NEW QUESTION # 13
An SMC system administrator is able to create conference administrators, common users, and other system administrators.
Answer: A
Explanation:
The Huawei Service Management Center uses role-based administration to provide centralized management of system accounts, organizational structures, conference users, and collaboration infrastructure.
The system administrator has the authority to create and configure conference administrators, common users, and additional system administrator accounts.
Huawei's Lab Guide demonstrates these operations in Experiment 3, Basic Configuration of the Video Conferencing System.
To create another system administrator, the administrator accesses the SMC system management interface and selects the appropriate administrator-management function. The new account is assigned the system administrator role. However, Huawei's documented procedure requires the account to undergo an authorization process before it becomes operational.
Conference administrators and common users are provisioned through Service Provisioning > Organization & User Management > Organization & Conference User.
Conference administrators receive permissions to manage conferences within their assigned organizational scope. Common users receive more restricted permissions for conference scheduling and participation.
These account categories allow the SMC to maintain administrative separation while supporting centralized user management.
The important distinction is that creating an account does not necessarily mean it becomes immediately usable. Administrator authorization and account activation may be required.
Therefore, the statement is true.
Huawei reference: Lab Guide, Sections 3.3.1, Creating a System Administrator; 3.3.3, Creating a Common User; 3.3.4, Creating a Conference Administrator, PDF pages 69-77.
NEW QUESTION # 14
What are the six request methods of a SIP message?
Answer: A
Explanation:
Session Initiation Protocol (SIP) is an application-layer signaling protocol used to establish, modify, and terminate multimedia communication sessions. SIP operates through request-response exchanges between User Agent Clients (UACs), User Agent Servers (UASs), and intermediary network servers.
Huawei's HCIA-Collaboration Training Material identifies six basic SIP request methods: INVITE, ACK, CANCEL, BYE, REGISTER, and OPTIONS.
INVITE initiates a multimedia session or invites a participant to join an existing session. ACK acknowledges the final response to an INVITE request. CANCEL terminates a pending request before the corresponding transaction is completed. BYE terminates an established session. REGISTER updates the user's registration or contact information with a registration server. OPTIONS queries the capabilities supported by a SIP entity.
Option B contains all six basic request methods and is therefore correct.
Options A and D incorrectly substitute MESSAGE for ACK or OPTIONS. MESSAGE is an extended SIP method used for instant-message delivery.
Option C incorrectly substitutes UPDATE for OPTIONS. UPDATE is an extended method used to modify session parameters during session establishment.
The distinction between basic and extended SIP methods is explicitly defined in Huawei's protocol curriculum and is essential to interpreting SIP signaling procedures.
Huawei reference: Training Material, PDF pages 100-101, SIP Requests (1) and SIP Requests (2).
