QUESTION: 1

A small Internet company decides to deploy its services on Huawei Cloud during the early stages of development.
Which of the following is NOT an advantage of deploying services on Huawei Cloud?

Quick service deployment and rollout
Flexible resource scaling
Higher hardware performance with the same configuration
Reduced hardware costs

Answer(s): C

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

From the HCIACloud Computing learning scope, the core advantages of using cloud services (including Huawei Cloud) are typically tied to agility, elasticity, and cost efficiency.

Quick service deployment and rollout (A) is a standard cloud advantage because cloud providers offer ready-to-use services, templates, and automated provisioning. This allows businesses--especially startups--to launch environments in minutes instead of purchasing, shipping, installing, and configuring physical infrastructure.

Flexible resource scaling (B) is one of the most emphasized cloud characteristics. Cloud resources can be scaled up/down based on demand (elasticity), helping companies handle traffic spikes or reduce capacity during off-peak times without long procurement cycles.

Reduced hardware costs (D) is also a common advantage because the company avoids large upfront capital expenses (CapEx) for servers, storage, and networking. Instead, cloud typically follows a pay- as-you-go model (OpEx), which is ideal for early-stage businesses with uncertain growth.

However, Higher hardware performance with the same configuration (C) is not an inherent cloud advantage. If the virtual machine configuration (CPU, memory, disk type) is the same, cloud does not automatically guarantee higher performance than equivalent hardware elsewhere. Performance depends on factors such as underlying physical host load, storage type, network conditions, and service class--so "higher performance with the same configuration" is not a guaranteed benefit and therefore is the incorrect "advantage."

Important note (transparency): I can format and answer based on HCIA domain concepts, but I cannot provide "exact extracts" from Huawei official copyrighted documents in a verbatim way.

QUESTION: 2

Which of the following statements is false about the development of cloud computing architecture?

In terms of cloud platforms and cloud management software, it has evolved from closed-source and closed architecture to open-source and open architecture.
It has evolved from non-critical IT applications to critical enterprise applications.
It has evolved from unstructured or semi-structured data to structured data.
It has evolved from small-scale resource virtualization and integration to large-scale resource pool construction.

Answer(s): C

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

According to the HCIACloud Computing curriculum, the evolution of cloud computing architecture reflects changes in technology openness, business importance, resource scale, and data characteristics.

Option A is correct because early cloud platforms were often proprietary and closed, while modern cloud computing architectures increasingly adopt open-source technologies (such as OpenStack and Kubernetes) and open architectures to improve interoperability and innovation.

Option B is also correct. Cloud computing initially hosted non-critical workloads such as testing, development, and backup systems. As reliability, security, and availability improved, cloud platforms became capable of supporting mission-critical enterprise applications, including ERP, financial systems, and core business services.

Option D correctly describes the evolution of cloud architecture. Early virtualization focused on small-scale resource integration, while modern cloud computing emphasizes large-scale resource pools, enabling centralized management, elastic scheduling, and efficient utilization of massive compute, storage, and network resources.

Option C is false. The evolution of cloud computing data has moved from structured data to semi- structured and unstructured data, not the other way around. With the rise of big data, IoT, social media, logs, images, and videos, cloud platforms are increasingly designed to process massive volumes of unstructured and semi-structured data, which is a key trend emphasized in HCIA learning materials.

QUESTION: 3

The service modes for cloud computing include Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS).
Which of the following statements are false about the IaaS model?

Users need to install a virtualization suite to integrate resources.
Users only need to pay attention to applications.
Users only need to focus on applications and data.
Users only need to focus on systems and applications.

Answer(s): A,B,C

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

The HCIACloud Computing syllabus clearly defines responsibility boundaries for IaaS. In the IaaS model, the cloud provider delivers basic infrastructure resources, including compute, storage, networking, and virtualization. The user is responsible for managing operating systems, middleware, runtime environments, applications, and data.

Option A is false because virtualization is managed by the cloud provider, not the user. In IaaS, users consume virtualized resources (such as ECS instances) but do not deploy or maintain the underlying hypervisors or virtualization platforms.

Option B is false. Only focusing on applications aligns with the SaaS model, where the provider manages everything else. In IaaS, users must also manage operating systems and system-level configurations.

Option C is also false. Focusing only on applications and data corresponds more closely to PaaS, where the platform handles operating systems and runtime environments.

Option D is the correct description of IaaS responsibilities, because users must manage operating systems (systems) and applications, while the provider manages the infrastructure layer. Therefore, D is not false and is excluded from the answer.

QUESTION: 4

The Central Processing Unit (CPU) is the computer's computing and control core. Mainly composed of an arithmetic logic unit (ALU) and a controller, it reads and executes data according to instructions.

TRUE
FALSE

Answer(s): A

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

According to the HCIACloud Computing curriculum under Server Basics, the CPU is defined as the core component responsible for computation and control within a computer system. The CPU executes program instructions and coordinates the operation of all other hardware components.

The CPU is primarily composed of two main functional units:

Arithmetic Logic Unit (ALU): Responsible for performing arithmetic operations (such as addition and subtraction) and logical operations (such as comparisons and logical AND/OR).

Control Unit (Controller): Responsible for fetching instructions from memory, decoding them, and controlling the execution process by issuing control signals to other components.

The CPU operates based on the fetchdecodeexecute cycle, which is a fundamental concept emphasized in HCIA learning materials. During this process, the CPU reads instructions and related data from memory, processes them, and produces results according to the instruction set architecture.

Because the statement accurately describes the role, composition, and working principle of the CPU as defined in Huawei's HCIACloud Computing documentation, it is correct.

QUESTION: 5

Which of the following statements is false about Redundant Array of Independent Disks (RAID)?

RAID 0 uses striping to improve data read and write performance.
RAID 6 uses mirroring to ensure user data reliability.
RAID 1 uses mirroring to ensure user data reliability.
RAID 5 uses parity check to ensure data reliability.

Answer(s): B

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

RAID technology is a key topic in the Storage Technology Basics domain of HCIACloud Computing. Different RAID levels provide varying balances of performance, capacity, and fault tolerance.

RAID 0 (A) uses data striping across multiple disks to improve read/write performance but provides no data redundancy. This statement is correct.

RAID 1 (C) uses disk mirroring, where identical data is written to two disks, ensuring high data reliability. This statement is correct.

RAID 5 (D) uses distributed parity across disks, allowing data recovery if one disk fails. This is also correct.

RAID 6 (B) is the false statement. RAID 6 does not use mirroring. Instead, it uses dual parity, allowing the system to tolerate the failure of two disks simultaneously.

Therefore, option B is incorrect and is the false statement.

QUESTION: 6

Which of the following statements are true about distributed storage?

Distributed storage features outstanding scalability.
Distributed storage typically uses general-purpose servers rather than storage devices.
Distributed storage leverages RAID technology to ensure high data availability and security.
Distributed storage has no controller enclosure or disk enclosure. All disk storage resources are delivered by general-purpose servers.

Answer(s): A,B,D

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

Distributed storage is a core concept in cloud computing and is emphasized in HCIACloud Computing as a foundational technology for large-scale cloud platforms.

Option A is true. Distributed storage is designed for horizontal scalability, allowing storage capacity and performance to increase simply by adding more nodes.

Option B is true. Unlike traditional centralized storage systems, distributed storage typically runs on general-purpose x86 servers, reducing cost and improving flexibility.

Option C is false. Distributed storage does not rely on traditional RAID for data protection. Instead, it uses data replication or erasure coding, which are more suitable for large-scale distributed environments.

Option D is true. Distributed storage eliminates the need for dedicated controller enclosures or disk enclosures. Storage resources are directly provided by general-purpose servers, which aligns with cloud-native architecture principles described in HCIA materials.

QUESTION: 7

A switch can learn the source and destination MAC addresses of traffic and add the addresses to a MAC address table. It cannot isolate collision domains.

TRUE
FALSE

Answer(s): B

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

In the HCIACloud Computing curriculum, Ethernet switches are core components of the data center network and operate mainly at the data link layer. One of their key functions is MAC address learning.
When a switch receives a frame, it records the source MAC address and the corresponding incoming port in the MAC address table. This allows the switch to forward subsequent frames intelligently.

More importantly, a switch can isolate collision domains, which makes the statement false. Each switch port represents an independent collision domain, meaning that collisions occurring on one port do not affect other ports. This is a major improvement over hubs, which place all connected devices in a single collision domain.

However, switches do not isolate broadcast domains by default. Broadcast traffic is forwarded to all ports within the same VLAN. Broadcast domain isolation requires technologies such as VLANs or routers.

Since the statement claims that a switch cannot isolate collision domains, which contradicts the HCIA definition of switching behavior, the correct answer is FALSE.

QUESTION: 8

Which of the following statements are false about VLAN technology?

A trunk link allows untagged packets from multiple VLANs to pass through.
A hybrid interface cannot be used to connect a switch and a server.
A trunk interface is used to connect switches.
An access interface is used to connect switches.

Answer(s): A,B,D

Explanation:

Comprehensive and Detailed Explanation (HCIACloud Computing aligned):

VLAN technology is a fundamental topic in HCIACloud Computing, especially for cloud network isolation and segmentation.

Option A is false. A trunk link is designed to carry traffic from multiple VLANs using VLAN tags (802.1Q). Untagged traffic typically belongs to a native VLAN, not multiple VLANs.

Option B is false. A hybrid interface can be used to connect a switch to a server. Hybrid interfaces support both tagged and untagged VLAN traffic and are commonly used in server and virtualization scenarios.

Option C is true. Trunk interfaces are primarily used to connect switch-to-switch links, allowing multiple VLANs to pass between switches.

Option D is false. Access interfaces are designed to connect end devices (such as PCs or printers) and carry traffic for only one VLAN, not for switch interconnections.

Therefore, the false statements are A, B, and D.
