NEW QUESTION # 18
Which of the following messages are SIP requests?
Choose two
Answer: A,D
Explanation:
The Session Initiation Protocol (SIP) is an application-layer signaling protocol used to establish, modify, and terminate multimedia communication sessions.
SIP messages are divided into two fundamental categories: requests and responses.
Option A, CANCEL, is a SIP request used to cancel a pending request before the associated transaction has completed. It is commonly used when a caller withdraws a call attempt before session establishment.
Option B, REGISTER, is also a SIP request. Its purpose is to register or update a user's contact information with a SIP registration server, allowing the system to associate the user's logical identity with a reachable network location.
Options C and D are not SIP requests. They are SIP response-code classes.
The 3xx response class represents redirection. It indicates that additional action is required, typically involving an alternative destination, to complete the requested operation.
The 2xx response class represents successful processing. For example, a 200 OK response indicates that a SIP request has been accepted and processed successfully.
Huawei's Training Material explicitly lists CANCEL and REGISTER among the six basic SIP request methods and identifies the 2xx and 3xx ranges as SIP responses.
Therefore, the correct selections are A and B.

NEW QUESTION # 19
A service area may contain multiple MCUs and RSEs.
Answer: A
Explanation:
In Huawei's video conferencing architecture, a service area is a logical resource-management domain used by the Service Management Center to organize and allocate conferencing resources.
A service area can contain multiple Multipoint Control Units and recording and streaming servers. The SMC manages these devices as resource pools and schedules services according to available capacity and applicable service-area matching rules.
Multiple MCUs within a service area enable the system to distribute participant connections, increase conference capacity, and provide redundancy. When one MCU cannot accommodate the required participants, automatic cascading may allow additional MCUs to contribute conference resources.
Similarly, multiple RSEs support scalable recording and streaming services. The SMC can select appropriate recording resources based on availability and resource utilization. Backup mechanisms help maintain service continuity when individual devices become unavailable.
Huawei's Training Material explicitly illustrates service areas containing multiple MCUs and explains that each service area is allocated MCU and RSE resources. It also describes load balancing and backup capabilities across these resources.
Therefore, the statement is true. A service area is not restricted to a single MCU or a single recording and streaming server. Its purpose is to provide a coordinated resource-management boundary that can include multiple devices.

NEW QUESTION # 20
Which of the following basic request messages is used to terminate a session?
Answer: C
Explanation:
SIP provides different request methods for controlling the lifecycle of multimedia communication sessions.
Each method performs a specific signaling function.
The BYE request terminates an established SIP session. Either participant can initiate a BYE request when the communication must end. After the request is processed successfully, the receiving entity returns a final response, typically 200 OK, completing the session-termination signaling procedure.
Option C is therefore correct.
Option A, CANCEL, terminates a pending request before the associated transaction has completed. It is commonly used to cancel an unanswered call attempt. CANCEL does not terminate an already established session.
Option B, ACK, acknowledges the final response to an INVITE request. Its purpose is to complete the relevant INVITE signaling procedure rather than terminate a session.
Option D, INVITE, initiates a multimedia session or changes an existing session through a subsequent INVITE exchange. It is not the standard method for terminating an established session.
Huawei's Training Material explicitly identifies BYE as the basic SIP request used to release an established call.
The examination distinction is between canceling an incomplete session-establishment attempt and terminating a session that has already been established. CANCEL addresses the former condition, while BYE addresses the latter.

107, Non-INVITE Transactions.
NEW QUESTION # 21
SEC's core technology generates verification packets before data is transmitted by using Huawei's proprietary data-verification algorithm. If packet loss occurs during transmission, these verification packets can restore the missing packets and ensure data reliability.
Answer: A
Explanation:
The statement describes a proactive packet-recovery mechanism in which redundant verification information is generated before transmission and subsequently used to reconstruct missing information if packet loss occurs.
This type of protection is technically consistent with forward error correction. Instead of relying exclusively on retransmitting missing packets after the receiver detects loss, the sender transmits additional information that can support recovery at the receiving endpoint.
Such mechanisms are particularly useful for real-time video conferencing, where retransmission delays may exceed the time available for smooth media playback.
Huawei's SEC technology is designed to improve packet-loss tolerance and maintain video quality under adverse network conditions. The Training Material confirms that SEC supports video protection at packet-loss rates reaching 30%, including scenarios involving 12 consecutively lost packets.
The described verification-packet process provides a technically coherent explanation of how a redundancy- based recovery mechanism could support these capabilities.
Nevertheless, the exact sequence involving Huawei's proprietary verification algorithm, generation of verification packets before transmission, and restoration of lost packets is not described in the supplied V4.0 Training Material or Lab Guide.
Verification finding: TRUE is a provisional technical interpretation, not a fully source-verified answer. The provided documentation establishes SEC's intended packet-loss protection capability but does not establish the specific proprietary algorithm described in the question.

NEW QUESTION # 22
Which statement below is false regarding the video-download and network-storage capabilities of the recording & streaming server (RSE)?
Answer: A
Explanation:
The Huawei recording and streaming server provides conference recording, live streaming, video-on-demand playback, video download, and expandable storage services. The distinction in this question concerns the conditions associated with downloading presentation videos rather than the availability of download functionality.
The Training Material explicitly identifies two download capabilities: users can download encrypted TS video files online, and presentations attached to recordings can also be downloaded. However, it does not establish a separate approval requirement specifically for downloading an attached presentation. Therefore, option A introduces an authorization condition that the relevant course section does not substantiate.
Option B is consistent with the documented ability to download recorded video content. Options C and D are both supported because the RSE provides local disk storage and can mount external network storage through IP SAN and NFS. These technologies expand available storage capacity and support the protection of recorded conference files.
Verification concern: Option A is the intended exception, but the wording is not conclusively false. Download authorization may depend on permissions, and the training material does not expressly prohibit approval- based access. Consequently, the question should be flagged as ambiguous rather than treated as an unequivocally verified key.
