Question 1

A route table refers to the list of routing entries on a VRouter in an Alibaba Cloud VPC. You can create/delete any route tables in a VPC.

ATrue

BFalse

Answer : B

In Alibaba Cloud VPCs, only custom route tables can be created and deleted by users. The default route table associated with each VPC cannot be deleted, although custom routing entries within it can be modified. This limitation ensures the integrity of essential VPC networking components.

Question 2

As a technical employee at a startup company, you deploy static files such as images and videos on the same ECS instance to provide services. After some time, due to business growth, you find that these static files are using too much ECS disk space. To quickly address this issue, you should choose Alibaba Cloud _________________.

AServer Load Balancer (SLB)

BApsaraDB for RDS

CObject Storage Service (OSS)

DAuto Scaling

Answer : C

Alibaba Cloud Object Storage Service (OSS) is ideal for storing large amounts of unstructured data, such as images and videos. By migrating static files to OSS, you can free up disk space on your ECS instance, allowing you to efficiently handle storage needs as your business scales. OSS is a highly scalable and cost-effective solution for handling media files and other static assets.

Question 3

You deployed a website on an Alibaba Cloud Elastic Compute Service (ECS) instance. After some time, you are concerned that the ECS instance might be compromised by brute-force password cracking. To address this issue, you can use Alibaba Cloud's ________________ product.

AObject Storage Service

BCloudMonitor

CServer Load Balancer

DSecurity Center

Answer : D

Alibaba Cloud Security Center is designed to enhance the security of ECS instances by providing proactive monitoring, vulnerability detection, and protection against threats such as brute-force attacks. Security Center includes features such as brute-force attack detection, which will alert you to and help mitigate potential threats to your ECS instance.

Question 4

Alibaba Cloud SLB includes components like external service requests, Listeners, Load Balancer, Backend Servers, etc. Which of the following statements is correct about Listeners?

AA Listener includes SLB policies and forwarding rules.

BA Listener is a collection of ECS instances that provide external services.

CA Listener refers to an SLB instance.

DBy configuring monitoring rules, a Listener can generate monitoring metrics for SLB.

Answer : A

In SLB, a Listener is configured with policies and forwarding rules that define how the load balancer will handle incoming requests, including protocol, port, and health check configurations. It does not represent an SLB instance itself or a collection of ECS instances, but it plays a crucial role in managing traffic routing and session persistence.

Question 5

Using Alibaba Cloud ECS, SLB, and Auto Scaling in combination, you can build a stable, efficient, and secure system at a low cost. This system can distribute loads based on predefined policies and automatically scale resources with changing business volume. Which of the following statements is correct?

AAn SLB instance can bind multiple Auto Scaling groups, and the scaling configurations of these scaling groups can be different.

BAn SLB instance can bind multiple Auto Scaling groups, but the scaling configurations of these scaling groups must be consistent.

CA scaling group may correspond to multiple SLB instances, but they must be within the same region.

DA scaling group may correspond to multiple SLB instances, but they must be within the same zone.

Answer : C

In Alibaba Cloud, a scaling group can be associated with multiple SLB instances as long as they are in the same region, allowing distributed load handling across multiple load balancers. However, there is no requirement for SLB instances or scaling configurations to be in the same zone, making it region-specific instead of zone-specific.

Question 6

Which of the following is not a potential cause of latency on an RDS read-only instance?

AThe load on this read-only instance is significant.

BThere exists significant load on the ECS that is connected to this read-only instance.

CThe specification of this read-only instance is too low.

DThis read-only instance's master instance is performing a lot of write operations.

Answer : B

Latency on an RDS read-only instance can be caused by high loads on the instance itself, inadequate instance specifications, or excessive write operations on the master instance, as these factors directly impact replication delay and resource contention. However, a high load on the ECS instance connected to the RDS read-only instance would not inherently cause latency on the RDS instance, as the ECS and RDS operate independently in terms of processing.

Question 7

Which of the following statements about an OSS bucket is NOT correct?

AEvery user can create more than one bucket.

BThe bucket name can be changed after creation.

CEvery bucket must have a unique name.

DThere is no limitation on the number of objects inside a bucket.

Answer : B

In Alibaba Cloud Object Storage Service (OSS), once a bucket is created, its name cannot be changed. This rule aligns with OSS's design to ensure global uniqueness and consistency in bucket naming across regions. Users can create multiple buckets, and each bucket can store an unlimited number of objects, provided the bucket name remains unique and immutable after creation.
