Free Huawei H13-811_V3.5 Practice Exam with Questions & Answers

Statements B and D are correct. Huawei Cloud CBR architecture consists fundamentally of backups, vaults, and policies. A vault is the storage container used by CBR for backup data. Huawei documentation explicitly states that CBR stores backups in vaults and that different resource categories are associated with appropriate vault types, such as server backup vaults and disk backup vaults.

Statement B is also directly supported. Huawei categorizes CBR policies into backup policies and replication policies. A backup policy automatically runs backup operations according to configured schedules and retention parameters, while a replication policy periodically replicates eligible backup data to another vault or region.

Statement A is incorrect because CBR is specifically designed to automate protection through policies; regular backups do not normally need to depend on repeated manual execution. Huawei advises using backup policies for scheduled protection.

Statement C is too absolute. CBR substantially improves recoverability against accidental deletion, malware, software failures, and hardware faults, but no backup architecture legitimately guarantees that data can never be lost under every conceivable condition.

Therefore, B and D are the verified statements.

The supported notification methods represented in this question are SMS and email , so the correct selections are A and D .

Huawei Cloud CTS supports key event notification for significant operations. Administrators can identify operations that require immediate awareness and configure notification delivery through Simple Message Notification (SMN). When the configured key event occurs, CTS works with SMN to deliver the corresponding notification to subscribed recipients.

Huawei's official CTS documentation specifically states that SMN can send key-event messages to users' mobile phones or email addresses . A notification sent to a mobile phone in this context corresponds to SMS messaging. Email subscriptions similarly deliver the notification to the registered email endpoint.

This mechanism provides proactive visibility into sensitive cloud operations rather than requiring administrators to continually query CTS records. Typical use cases include monitoring resource deletion, security configuration changes, permission-related operations, or other high-risk administrative actions.

Neither WeChat nor a conventional phone call is identified by Huawei CTS as one of the notification methods in this key-event mechanism. Those options therefore do not satisfy the documented CTS notification workflow.

Reference topics: CTS Key Event Notification; Simple Message Notification; Operation Auditing; O & M Notifications.

The statement is FALSE . Although an ECS group does logically organize ECS instances, its placement behavior is the opposite of what the second sentence states. Huawei Cloud ECS groups support the anti-affinity policy , which is designed to place ECS instances belonging to the same group on different physical hosts .

Anti-affinity is an availability and fault-isolation mechanism. If multiple application instances were placed on one physical server, failure of that host could simultaneously disrupt every application instance. Distributing the ECSs across different hosts reduces this correlated-failure risk and improves service reliability, high availability, and disaster tolerance.

Huawei's ECS documentation explicitly states that ECS groups support the anti-affinity policy and that ECSs in an anti-affinity group are deployed on different hosts. When an existing ECS is added to such a group, Huawei Cloud may even reallocate its host so that the placement requirement can be maintained.

Therefore, the first proposition—an ECS group logically groups ECSs—is valid. However, the assertion that ECSs in that group are created on the same physical server by default contradicts the anti-affinity design. Since the overall statement contains this incorrect condition, the correct answer is FALSE .

Reference topics: ECS Groups; Anti-Affinity Policy; Host Placement; High Availability.

===============

The statement is TRUE . Huawei Cloud makes an explicit architectural distinction between Elastic Cloud Servers and Bare Metal Servers regarding the underlying compute resources. An ECS is a virtualized compute instance. Multiple ECS instances can therefore consume resources provided by the same underlying physical host, with virtualization providing logical isolation between tenants and workloads.

A BMS, by contrast, provides exclusive access to physical compute resources. Huawei Cloud states directly that BMS users can exclusively access physical resources, whereas ECS users share those physical resources. This makes BMS particularly suitable for mission-critical systems, big-data clusters, enterprise middleware, high-performance workloads, and applications that require predictable performance or direct access to physical CPU and memory resources.

Huawei's BMS comparison also identifies Exclusive resources = Yes for BMS and traditional physical servers, but No for ECS. BMS additionally provides cloud characteristics such as automatic provisioning, VPC integration, image-based deployment, monitoring, and cloud storage while retaining physical-server performance.

Therefore, the differentiation presented in the question is technically accurate.

Huawei Cloud establishes a clear parent-child relationship between a Huawei Cloud account and the IAM users created under that account. The account owns the cloud resources and is the billing entity , whereas IAM users consume or manage resources according to permissions assigned by the account administrator.

Therefore, option C is correct: IAM users do not independently pay for the resources they use. Charges generated through their authorized operations are billed to the parent account. Options B and D are also correct because the account administrator retains authorization control and can modify or revoke permissions assigned to IAM users.

Option A is incorrect because it incorrectly treats the IAM user as a payment entity. Authorization determines what an IAM user is permitted to access or operate , not who is responsible for payment. Huawei Cloud explicitly distinguishes resource ownership and billing from delegated resource access. An IAM user does not receive an independent bill merely because access to a resource has been authorized.

Accordingly, the correct relationship is: account owns and pays; IAM users operate resources according to delegated permissions; the account controls those permissions .

Option A is the only sequence that respects the essential dependency chain for Huawei Cloud Log Tank Service host-log collection. A log group must exist before its log stream can be created , because a log stream is a subordinate storage and management unit within a log group. Huawei explicitly describes log groups and streams as the basic units used to manage logs and requires creation of the group before creation of its contained stream.

ICAgent is the host-side log collection component. It must be installed on the ECS before LTS can collect host log files according to configured paths and rules. After ICAgent is operational and the destination log stream exists, the administrator configures the relevant collection paths, parsing/collection rules, and ingestion configuration. ICAgent then packages and reports matching log records into the selected log stream.

Only after ingestion has been configured can the administrator reliably access LTS and view the collected logs for searching, analysis, monitoring, troubleshooting, or O & M.

The other alternatives violate basic dependencies by attempting to create a stream before its parent group, configuring collection before the required destination/agent exists, or installing ICAgent after collection configuration.

===============

The statement is TRUE . Huawei Cloud distinguishes ordinary EVS disks from shared EVS disks . A standard non-shared EVS disk can normally be attached to only one server at a time, whereas a shared disk is specifically designed so that multiple supported servers can access the same block-storage device. Huawei documentation states that a shared EVS disk can be attached to multiple servers simultaneously, with supported implementations allowing attachment to as many as 16 servers.

The deletion requirement is equally explicit. A shared EVS disk cannot remain attached to any server when the disk itself is being deleted. Huawei requires administrators to detach the shared disk from all servers before deletion . If the disk is attached to several servers and is detached from only some of them, it remains in the In-use state. Only after it has been detached from every server does its state return to Available, permitting subsequent deletion operations.

Huawei additionally cautions that shared block storage does not itself provide cluster coordination. Appropriate cluster software or shared-file-system mechanisms must manage simultaneous reads and writes to prevent corruption.

Thus, both parts of the question precisely reflect Huawei Cloud's EVS shared-disk lifecycle requirements.

===============

Option D is incorrect . The HCIA-Cloud Service V3.5 comparison positions SFS Capacity-Oriented as the large-capacity, high-bandwidth, cost-sensitive file-storage option. Huawei describes its principal advantages as large capacity, high bandwidth, and low cost , making it particularly appropriate for media processing, large-scale file sharing, HPC, and backup workloads.

The performance characteristics also support A and B. Huawei's documented SFS Capacity-Oriented implementation provides substantially greater maximum aggregate bandwidth than the previous-generation SFS Turbo Standard class. However, its access latency is approximately 3–20 ms , whereas SFS Turbo Standard provides lower latency, historically around 2–5 ms . SFS Turbo is therefore more appropriate where low-latency access and workloads involving large numbers of small files are important.

Capacity-Oriented storage can scale to petabyte-scale capacities and is specifically optimized economically for large-volume storage. Consequently, for equivalent expenditure, it can provide significantly greater capacity than performance-oriented SFS Turbo configurations.

Option D reverses this economic relationship. SFS Capacity-Oriented is not positioned as the more expensive alternative for equal capacity; low cost at large scale is one of its defining characteristics .

Options B, C, and D identify problems that CDN architecture is designed to mitigate. Huawei defines CDN as an intelligent virtual network built on Internet infrastructure that caches origin content on geographically distributed points of presence close to users. This substantially shortens the network path between users and frequently requested resources.

Consequently, CDN improves download speed because users can retrieve cached files from a nearby edge PoP rather than repeatedly crossing long-distance networks to the origin server. It also addresses slow website access by accelerating static content delivery, reducing latency, and improving site response and availability. Huawei specifically states that CDN breaks through bottlenecks associated with limited bandwidth, high access traffic, and uneven network-node distribution.

Caching popular content at edge nodes also reduces repeated traffic flowing through core and backbone networks. This alleviates bandwidth pressure on both the origin infrastructure and long-distance network paths.

Option A is not a CDN problem statement. CDN commonly reduces origin-server load , meaning utilization of origin resources may decrease rather than fixing a problem described as “low server utilization.” Its purpose is acceleration and traffic offloading, not increasing server utilization.

Therefore, B, C, and D are correct.

===============

Options B and C are incorrect because they reverse the isolation characteristics of IAM projects and enterprise projects . Huawei Cloud defines enterprise projects as a mechanism for grouping and managing resources across regions. Resources assigned to different enterprise projects are logically isolated , and a single enterprise project can contain resources residing in multiple regions. Supported resources can also be added to, removed from, or transferred between enterprise projects. Consequently, statements A and D correctly describe Enterprise Project Management.

IAM projects operate differently. Huawei Cloud documentation states that IAM projects are region-oriented and are used to group and physically isolate resources within a region . A project corresponds to a region, and an IAM project does not provide the cross-region logical grouping model associated with enterprise projects.

Therefore, B is wrong because it attributes physical, same-region isolation to enterprise projects, while C is wrong because it attributes logical isolation to IAM projects. The two concepts are intentionally distinguished in Huawei Cloud architecture: IAM project = regional/physical isolation; enterprise project = cross-region/logical resource organization .
