Alibaba ACP-Cloud1 Exam Questions Instant Access

Question 1

Company G developed a shopping App. The system is built using Alibaba Cloud products, including ECS instances and OSS in the North China 1 region, where static web pages and images are stored on OSS.

After the App went online, the access speed in mainland China was acceptable. Recently, the company decided to expand to the U.S. market and requires acceptable access speeds for U.S. users.

To address this requirement, Company G should select Alibaba Cloud _______________ service.

AEnabling Object Storage Service (OSS) + Content Delivery Network (CDN) in East China 1 and North China 2 regions

BEnabling Object Storage Service (OSS) + Content Delivery Network (CDN) in West US (Silicon Valley) region

CEnabling Auto Scaling and more Elastic Compute Service (ECS) instances

DEnabling Auto Scaling and Content Delivery Network (CDN)

Answer : B

To improve access speeds for U.S. users, Company G can enable OSS with CDN in the West US (Silicon Valley) region. By deploying CDN in a region close to the target audience, the static content stored in OSS can be cached and delivered more efficiently. CDN caches the content at edge locations, reducing latency for users in different geographical areas. This approach is ideal for expanding the application to international markets while maintaining fast access times.

Question 2

Alibaba Cloud OSS is a cloud storage service that features massive capacity, outstanding security, low costs, and high reliability. When talking about information security, the advantages of using OSS are ____________. (Choose two.)

ASupports Anti-DDoS, automatic traffic cleaning, and 'black holing' without any extra charges.

BOffers a multi-user isolation mechanism directly, with no need to leverage RAM.

COffers Server Side Encryption for data security protection in OSS.

DProvides Primary/Secondary region configuration for data reliability protection.

Answer : C, D

Alibaba Cloud OSS offers Server Side Encryption to protect data at rest, enhancing security. It also supports multi-region replication with Primary/Secondary region configurations for additional data reliability and disaster recovery. Anti-DDoS is not an inherent feature of OSS, and multi-user isolation is achieved via Alibaba Cloud's Resource Access Management (RAM).

Question 3

You have set an alert policy for the disk usage of an ECS instance by using Alibaba Cloud CloudMonitor. Each measurement cycle lasts for 5 minutes, during which the average disk usage is measured. If the average disk usage exceeds 80% for five consecutive measurement cycles, an alert will be reported. After your average disk usage exceeds 80%, how long will it take to receive an alert?

A0 minutes

B30 minutes

C40 minutes

D20 minutes

Answer : B

With a measurement cycle of 5 minutes and a requirement for five consecutive cycles where disk usage exceeds 80%, it would take 55=255 \times 5 = 2555=25 minutes for CloudMonitor to confirm the condition. After confirmation, CloudMonitor typically processes and sends the alert, which may take an additional 5 minutes, totaling approximately 30 minutes before you receive the alert.

Question 4

Alibaba Cloud Content Delivery Network (CDN) is a distributed network that is built and overlaid on the bearer network. It is composed of edge node server clusters distributed across different regions.

Alibaba Cloud CDN can directly accelerate an IP address. The accelerated website does not need to bind a domain name.

ATRUE

BFALSE

Answer : B

Alibaba Cloud CDN requires a domain name to function, as it uses DNS resolution to direct requests to the nearest edge nodes. CDN cannot directly accelerate an IP address without a domain name, so the statement is false.

Question 5

You deployed a MySQL database on an Alibaba Cloud Elastic Compute Service (ECS) instance. Due to increased traffic, there are more and more O&M tasks, such as database backup and Master/Slave database synchronization, and these tasks are becoming overwhelming.

Therefore, you can use Alibaba Cloud ___________ to solve this issue.

AAuto Scaling

BApsaraDB for RDS

CObject Storage Service

DTable Store

Answer : B

ApsaraDB for RDS is Alibaba Cloud's managed database service that simplifies O&M tasks for relational databases like MySQL. It offers built-in features for automatic backups, high availability, and Master/Slave synchronization, which reduces manual intervention and helps scale the database as traffic grows. By migrating to ApsaraDB for RDS, users can offload complex O&M responsibilities to Alibaba Cloud, ensuring a more efficient and scalable database solution for high-traffic applications.

Question 6

A company uses Alibaba Cloud SLB with a Layer-7 Listener and Auto Scaling to reduce O&M costs and maintain a stable, reliable system. However, lacking experience with Alibaba Cloud, the company's engineers have outlined precautions they think are necessary. As an Alibaba Cloud expert, you tell them that only ____________ is a valid concern.

ASLB instances must have Health Check enabled, or they cannot be used together with Auto Scaling.

BAll ECS instances under the same SLB instance must be running the same operating system.

CAll backend servers under the same SLB instance must be in the same Scaling Group.

DAll backend servers under the same SLB instance must have the same configuration.

Answer : A

For optimal use of SLB with Auto Scaling, enabling Health Check is essential to determine which instances are healthy and ready to handle traffic. SLB doesn't require all backend servers to have the same OS, be in the same scaling group, or have identical configurations, as it can manage heterogeneous server setups within the same load-balancing group.

Question 7

Which of the following statements is wrong about changing the specification of an RDS instance?

AThe specification of an RDS instance can be upgraded as needed

BThe service will not be interrupted during upgrade/downgrade

CThe database version cannot be downgraded

DMySQL 5.1 can be directly upgraded to MySQL 5.6

Answer : B

When changing the specifications of an RDS instance, service interruptions can occur during some upgrade and downgrade operations, depending on the RDS instance type and the complexity of the change. While upgrades are generally supported, certain modifications may result in brief downtime as the system reconfigures resources. This is contrary to option B. Additionally, database version downgrades are restricted, and MySQL 5.1 can indeed be upgraded directly to MySQL 5.6 in Alibaba Cloud RDS.
