Multiple answers9.When we say Cloud Native, we are talking about following aspects: (Number of correct answer: 3)
B. DevOps
C. CI/CD
D. OpenStack
When we talk about Cloud Native, we are indeed referring to:
A. Microservice: Cloud-native applications are software programs that
consist of multiple small, interdependent services called microservices.
B. DevOps: Cloud-native development brings along agile practices like
DevOps.
C. CI/CD: Cloud-native architecture means adapting to the many new
possibilities offered by the cloud compared to traditional on-premises
infrastructure. A well-architected cloud native system should be easily
updated and maintained through Continuous Integration/Continuous Delivery
(CI/CD).
D. OpenStack is not inherently a part of Cloud Native, it’s an
open-source software platform for cloud computing, but it’s not a defining
aspect of Cloud Native.
10.Which of the following can be used for container service logging and monitoring? (Number of correct answer: 3)
B. Cloud Monitor
C. Log Service
D. ACR
The correct answers are:
A. ARMS: Alibaba Cloud’s Application Real-Time Monitoring Service
(ARMS) can monitor and analyze user behavior and page performance in client
environments such as browsers, mini programs, and mobile apps1. It can also
monitor service calls, database queries, and system loads in distributed or
microservices architectures and container-based or serverless deployment
environments.
B. Cloud Monitor: Alibaba Cloud Monitor allows monitoring of cloud
resource usage and health of the application/resources by collecting various
monitoring metrics4567. It can monitor the status of nodes and applications in
ACK clusters8.
C. Log Service: Alibaba Cloud’s Simple Log Service can collect logs
from multiple types of Alibaba Cloud services, such as elastic computing,
storage, security, and database services9. It provides the Log Audit Service
application that collects logs across accounts from the following Alibaba
Cloud services: ActionTrail, Container Service for Kubernetes (ACK), Object
Storage Service (OSS), Apsara File Storage NAS (NAS), Server Load Balancer
(SLB), Application Load Balancer (ALB), API Gateway, Virtual Private Cloud
(VPC), ApsaraDB RDS, PolarDB, Web Application Firewall (WAF), Anti-DDoS, Cloud
Firewall, and Security Center.
D. ACR: Alibaba Cloud Container Registry (ACR) is a
secure image hosting platform that offers containerized management of
an image lifecycle1011. However, it is primarily used for managing Docker
images and does not directly provide logging and monitoring services for
container services.
Therefore, D. ACR is not a correct answer in this
context.
11.What are the 3 deployment modes for Alibaba Cloud Container Service (ACK)?
B. Managed
C. Serverless
D. Physically Owned
The three deployment modes for Alibaba Cloud Container Service (ACK) are:
A. Dedicated: In a dedicated deployment, you have your own set of
resources that are not shared with other users.
B. Managed: In a managed deployment, Alibaba Cloud takes care of the
underlying infrastructure, allowing you to focus on deploying and running your
applications.
C. Serverless: In a serverless deployment, you only pay for the actual
amount of resources consumed by applications, rather than pre-purchasing units
of capacity1. The platform automatically manages the infrastructure, allowing
developers to focus on writing code1.
D. Physically Owned is not a recognized deployment mode for Alibaba Cloud
Container Service (ACK), so D. Physically Owned is not a correct answer in
this context.

B. Node maintenance required
C. Node maintenance NOT required
D. Autoscaling on demand
The correct answers are:
A. Pay for workload: Serverless K8s clusters are designed to be
cost-effective, where you only pay for the actual amount of resources consumed
by applications, rather than pre-purchasing units of capacity.
C. Node maintenance NOT required: In a serverless K8s cluster, the
underlying infrastructure is abstracted away from the developer, meaning that
node maintenance is not required. The platform automatically manages the
infrastructure, allowing developers to focus on writing code.
D. Autoscaling on demand: Serverless K8s clusters can automatically
adjust capacity to maintain steady, predictable performance at the lowest
possible cost. They can scale up or down based on demand.
B. Node maintenance
is typically not required in a serverless K8s cluster, so B. Node maintenance
required is not a correct answer in this context.

A. Service discovery and load balancing: Kubernetes provides service
discovery and load balancing, giving Pods their own IP addresses and a single
DNS name for a set of Pods, and can load-balance across them.
C. Automated rollouts and rollbacks: Kubernetes progressively rolls out
changes to your application or its configuration, while monitoring application
health to ensure it doesn’t kill all your instances at the same time. If
something goes wrong, Kubernetes will rollback the change for you.
D. Self-healing: Kubernetes has self-healing capabilities, it restarts
containers that fail, replaces and reschedules containers when nodes die,
kills containers that don’t respond to your user-defined health check, and
doesn’t advertise them to clients until they are ready to serve.
As for B. Performance auto-analysis, there’s no evidence from my search results
that Kubernetes provides a feature called Performance auto-analysis.
