Question 1. (Multi Select)
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?
A: Users need to install a virtualization suite to integrate resources.
B: Users only need to pay attention to applications.
C: Users only need to focus on applications and data.
D: Users only need to focus on systems and applications.
Answer: A, B, C
Explanation:
Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):
The HCIA–Cloud 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 2. (Single Select)
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?
https://pass2certify.com//exam/h13-511_v5.5 Page 2 of 7
A: Quick service deployment and rollout
B: Flexible resource scaling
C: Higher hardware performance with the same configuration
D: Reduced hardware costs
Answer: C
Explanation:
Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):
From the HCIA–Cloud 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 4. (Single Select)
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.
A: TRUE
B: FALSE
Answer: B
https://pass2certify.com//exam/h13-511_v5.5 Page 4 of 7
Explanation:
Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):
In the HCIA–Cloud 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 5. (Multi Select)
Which of the following statements are false about VLAN technology?
A: A trunk link allows untagged packets from multiple VLANs to pass through.
B: A hybrid interface cannot be used to connect a switch and a server.
C: A trunk interface is used to connect switches.
D: An access interface is used to connect switches.
Answer: A, B, D
Explanation:
Comprehensive and Detailed Explanation (HCIA–Cloud Computing aligned):
VLAN technology is a fundamental topic in HCIA–Cloud 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.
