NEW QUESTION # 18
Both Cloud Connect and Direct Connect can establish high-speed, low-latency networks. Which of the following statements regarding their differences is false?
Answer: D
Explanation:
"Cloud Connect provides both cloud connections and central networks."
"Cloud Connect can also work with Direct Connect to set up a hybrid cloud network that enables on-premises data centers to access the VPCs across regions." Huawei source: Training PDF p. 146 Technical Deep Dive Direct Connect and Cloud Connect solve different segments of enterprise networking. Direct Connect creates high-speed private connectivity between an on-premises data center and Huawei Cloud through a dedicated physical link. Cloud Connect provides private inter-region connectivity using cloud connections and central networks, and can work alongside Direct Connect to extend on-premises reachability to VPCs across supported regions.
Option A accurately characterizes Direct Connect. Option B describes the documented hybrid pattern: attach on-premises infrastructure to the cloud, then interconnect VPCs in other regions through Cloud Connect.
Option D also matches the official Cloud Connect feature description. Option C is false because it presents Elastic IPs as the mechanism by which Cloud Connect establishes private on-premises-to-cloud communications. EIPs are public addressing resources, not the inter-region backbone or the dedicated customer access circuit.
A typical design is: on-premises data center - > Direct Connect - > VPC - > Cloud Connect - > remote VPC.
Routing must be configured end to end, with appropriate CIDR planning, propagation, bandwidth allocations and security controls. High availability may require redundant physical circuits, dual customer routers, resilient BGP sessions and careful route-preference design. Neither Cloud Connect nor Direct Connect removes the need for application-layer authentication and encryption where required by policy. The correct false statement is C; do not confuse a public EIP with private hybrid-cloud connectivity.
NEW QUESTION # 19
Elastic Load Balance (ELB) provides dedicated and shared load balancers. Which of the following statements about shared load balancers is false?
Select all that apply.
Answer: A,B
Explanation:
"Transfer Client IP Address is enabled for Layer 7 listeners by default. You do not need to manually enable it."
[Supporting description] Enabling Transfer Client IP Address for Layer 4 listeners preserves the client source IP rather than translating it to the 100.125.0.0/16 range.
Huawei source: Training PDF p. 166
Technical Deep Dive
The question asks which statements about shared Elastic Load Balance are false. Option B is false because client-IP transfer behavior is not enabled in the same way by default for both Layer 4 and Layer 7 listeners.
The Huawei V3.5 slide specifically states that Transfer Client IP Address is enabled by default for Layer 7 listeners; Layer 4 source-address preservation depends on the relevant listener setting.
Option D is also false. It reverses the behavior of enabling Transfer Client IP Address for a supported Layer 4 shared listener. When preservation is enabled, the backend receives the original client source address instead of a translated source address from the 100.125.0.0/16 range. Option A describes the shared ELB source- translation behavior when client-IP preservation is not applied and is generally true in the course context.
Option C is true because backend security groups and network ACLs must permit load balancer requests and health-check traffic.
Client identity matters for auditing, geographic restrictions, rate limiting and incident analysis. For Layer 7 HTTP and HTTPS forwarding, applications may also use an X-Forwarded-For header to identify the originating client, but this is not the same as packet-level source-IP preservation. Engineers must configure trust boundaries around such headers so that arbitrary client-supplied values are not accepted as authoritative.
The curriculum explicitly supports B and D as the false claims.
NEW QUESTION # 20
After a service website is connected to WAF, WAF acts as a reverse proxy between the client and server. All website access requests are first forwarded to WAF. WAF detects and filters malicious attack traffic, then sends normal traffic to the origin server to ensure that the origin server remains secure, stable, and available.
Answer: B
Explanation:
"After a website is connected to WAF, all HTTP and HTTPS requests (including attack requests from attackers and normal service requests from users) are checked by WAF. WAF filters out attack requests and forwards normal service requests to the web server."
"WAF works as a reverse proxy between the client and the origin server. All website access requests are forwarded to WAF first." Huawei source: Training PDF pp. 366, 369 Technical Deep Dive Huawei's V3.5 WAF chapter describes a reverse-proxy protection architecture in which incoming HTTP and HTTPS requests first reach Web Application Firewall before being forwarded to the origin web server. WAF inspects requests and filters malicious traffic such as SQL injection, XSS and command-injection attempts; allowed requests reach the application. The origin server processes those requests and sends responses back through the applicable WAF path, where supported response checks may be applied before delivery to clients.
This matches the statement, so answer A, TRUE.
For example, a malicious client can submit a URL parameter containing an SQL-injection payload. A configured WAF policy may recognize the suspicious request and block it, reducing the chance that the vulnerable application receives it. A normal customer request passes to the origin and receives the legitimate application response. This defensive layer is valuable but does not guarantee that every exploit will be detected, and applications still require secure coding and proper authentication.
Architecture matters. In CNAME-based proxy deployment, DNS directs protected website traffic through WAF; direct origin access should be restricted to avoid bypass. Huawei also offers ELB-access and dedicated modes whose traffic integration can differ, including out-of-path handling in some configurations. The true
/false statement is correct for the reverse-proxy model explicitly described by the source, but it should not be generalized without qualification to every physical packet path in every WAF mode. Verify TLS termination, client-IP forwarding, availability, log collection and origin security when planning a deployment.
Question 2 - The stem describes availability while labeling the concept as security; retain FALSE.
Question 3 - A third-party key may omit government incentives; Huawei V3.5 explicitly lists them.
Question 5 - Standard stopped pay-per-use ECS compute billing differs from special-instance or attached- resource billing.
Question 6 - The suggested M8/M7/M5 blanket recommendation is not established by the V3.5 workload table; the workload is underspecified.
Question 10 - Huawei text supports D as well as B and C; a B,C-only key is incomplete.
Question 11 - "Any region" is overbroad: connectivity depends on supported regions, provisioning, routing and compliance.
Question 13 - EIP is bound to NAT gateway, not simultaneously directly to target ECS; all-port mapping limits should be explicit.
Question 14 - Same-region inter-VPC networking should use VPC peering or private routing, not the posited VPN gateway-to-gateway scenario.
Question 17 - The resilience scenario describes multiple EIPs in SNAT, not DNAT.
Question 18 - An OS restart is not a required precondition for SFS deletion.
Question 19 - Partition tables MBR/GPT are supported in Windows; NTFS/FAT/exFAT are filesystems.
Question 20 - Corrected source typo dir0l to dir01; PFS has independently represented directories.
Question 22 - Original 2-answer wording overlooks D, which also incorrectly claims Common I/O is high- read-performance storage. Correct D or accept A,C,D.
Question 23 - Blackhole traffic dropping is distinct from DDoS traffic scrubbing.
Question 24 - Huawei CCE DNAT is platform-specific, not an upstream Kubernetes Service.spec.type.
Question 26 - Kubelet may also run on a control-plane host; question should ask for control-plane components rather than components that merely run on master nodes.
Question 28 - A crashed process may restart by restartPolicy without a liveness probe; the probe specifically drives restarts when liveness checks fail.
Question 29 - VPC network is another official CCE model but is not provided as an answer option.
Question 32 - A incorrectly binds an EIP to the cluster rather than node/load balancer. D requires routing
/peering in addition to security groups. Earlier choose-three intent differs from literal key.
Question 34 - Option B merges separate terms Dubbo and Service Mesh into "Dubbo mesh"; revise it so D is uniquely wrong.
Question 37 - No valid incorrect option: all four claims match the cited ASM course. Replace one answer choice or withdraw item.
Question 38 - Option A refers specifically to content-based grayscale routing; other grayscale policies can use traffic ratios.
Question 39 - RPO seconds is erroneously labeled RTO seconds. Course states RTO under 30 minutes.
Question 43 - D (WAN quality monitoring) is a monitoring capability, not a cloud resource; CCE metrics are principally surfaced through AOM/Prometheus rather than as listed generic Cloud Eye metrics.
Question 44 - HSS, not CBH, is associated with vulnerability checks, baseline checks and web tamper protection.
Question 45 - Asynchronous migration is not a distinct named DRS function in the V3.5 classification.
Question 46 - Log structuring is configured per log stream rather than per log group; A is false.
Question 48 - External Prometheus/Grafana monitoring integration exists, so C is false.
Question 50 - A and B are both inaccurate under qualified official documentation; single-answer item needs revision.
Question 51 - Source ODT stores IoT choices as screenshot; original unchanged exhibit included.
Definitions IoTA/IoTDP supplemented from official product documentation.
Question 54 - WebSocket/SSE pass-through support does not guarantee all WebSocket payloads are inspected like standard HTTP requests.
Question 55 - Self-signed certificates can establish TLS connections; they lack automatic public trust rather than Internet connectivity.
Question 56 - Reverse-proxy explanation applies to relevant WAF deployment modes; ELB/out-of-path modes have architectural distinctions.

NEW QUESTION # 21
A user has purchased an Elastic Cloud Server (ECS) with the c6s.6xlarge.2 flavor on Huawei Cloud. Which of the following statements about this ECS flavor are correct?
Select all that apply.
Answer: A,B
Explanation:
"A flavor name usually consists of the instance family and generation, instance size, and memory/vCPU ratio."
[The naming slide] An Nxlarge instance size denotes N × 4 vCPUs; the ending ratio specifies GiB of memory for each vCPU.
Huawei source: Training PDF p. 57
Technical Deep Dive
Huawei ECS flavor names encode the instance family, size and memory-to-vCPU ratio. In c6s.6xlarge.2, the family prefix c6s denotes a general computing-plus generation. The size label 6xlarge specifies six units of four virtual CPUs. Thus six multiplied by four equals 24 vCPUs: option A is correct.
The suffix .2 represents two GiB of memory for each vCPU. Multiplying 24 by two gives 48 GiB of RAM:
option C is correct. Option B incorrectly claims 64 GiB, while option D incorrectly claims 12 vCPUs. The arithmetic follows the naming convention rather than any assumption about current flavor availability.
General computing-plus instances are designed for stable CPU and networking performance. Huawei's V3.5 training also discusses the QingTian infrastructure architecture, in which dedicated hardware acceleration can offload selected virtualization and I/O processing from hosts, helping reduce interference with tenant workloads. Hardware offloading is relevant to the platform's performance characteristics, but it does not alter the vCPU or RAM calculation encoded in the flavor name. During solution design, use the full specification table to validate networking and disk limits, available regions, and guest-system support, because flavor naming alone does not describe every performance characteristic. The verified result is 24 vCPUs and 48 GiB.
Technical commands / calculations from the reviewed batch
6 × 4 = 24 vCPUs
24 × 2 = 48 GiB RAM
NEW QUESTION # 22
After a user attaches a newly created data disk to an Elastic Cloud Server (ECS), the Elastic Volume Service (EVS) disk must be initialized-including creating partitions and file systems and mounting the partitions- before it can be used. Which of the following statements about disk initialization isfalse?
Answer: A
Explanation:
"The newly attached block storage device can be used only after it is formatted."
[Lab Guide, storage exercise] The lab shows formatting with mkfs -t ext4 /dev/vdb, mounting the filesystem, and setting /etc/fstab for automatic mounting.
[The partition-table distinction is also supported by official EVS documentation. ] Huawei source: Lab Guide PDF p. 125; Training PDF EVS section; official EVS docs Technical Deep Dive A newly attached EVS block device generally needs initialization before it can be used as a new filesystem.
Option A is true: MBR and GPT partition styles can be used for smaller disks, while GPT is needed for capacities beyond MBR's practical approximately two-TiB limit. Option B is true: on Linux, an initialized disk can be mounted using the mount command, and persistent mounting is typically configured through /etc
/fstab using a stable filesystem UUID.
Option C is false. Windows supports both MBR and GPT partition tables. NTFS, FAT and exFAT are filesystem formats, not replacements for partition-table standards. Treating a filesystem type as a partition style is a fundamental storage-administration error. Option D is true: Linux tools such as fdisk and parted can create partitions, and commands such as mkfs.ext4 create filesystems on the appropriate block device or partition.
The Huawei V3.5 Lab Guide shows formatting and mounting a newly attached disk, including configuring persistent mounting. A safe production workflow is to identify the disk with lsblk, verify it contains no required data, create an appropriate GPT partition if needed, format it and mount it to a chosen directory.
Formatting or changing a partition table destroys existing data, so the target device must be checked carefully.
For Windows, administrators use Disk Management or appropriate PowerShell commands to initialize a disk with MBR or GPT and format a volume using NTFS or another supported filesystem. Answer C is unambiguously incorrect.
