AVirtual Private Cloud (VPC) is an isolated network environment that is completely isolated from each other. The following statements about VPC are correct______. (Number of correct answers: 2)
- A . Each VPC has an independent tunnel ID, and a tunnel ID corresponds to a virtualized network.
- B . Subnets can be divided like the traditional network environment. Different cloud servers within each subnet are connected by the same router, and different subnets are interconnected by switches.
- C . The internal networks of different VPCs are completely isolated and can be interconnected through IP addresses mapped to the outside.
- D . ECS instances in a VPC use security group firewalls for Layer 2 network access control.
You are using Auto Scaling with one scaling group already created, then you want to execute a task at a specific time such as removing 1 ECS instance every night at 00:00.
To achieve this, which of the following operations should be performed? (Number of correct answers: 2)
- A . Create a new scaling group.
- B . Create a scaling rule.
- C . Create a scheduled task.
- D . Create an event-triggered task.
Availability Zones refer to data centers in the same region with independent power grids and networks.
Which of the following statements are true for Zones? (Number of correct answers:3)
- A . if the disaster recovery requirements of your applications are demanding it is recommended that you deploy ECS instances in the same Region and Zone.
- B . The network latency between inter-Zone ECS instances is lower.
- C . Intranet communication is available between different zones in the same region, and datacenter level fault isolation can be achieved between Zones.
- D . whether you place ECS instances in the same Zone depends on the requirements on disaster recovery and network latency.
- E . if your applications require a low network latency between ECS instances, it is recommended that you create ECS instances in different Zones.
Alibaba Cloud Content Delivery Network (CDN) is a distributed network that is built and overlaid on the bearer network. Moreover, it is composed of edge node server clusters distributed across different regions.
It replaces the traditional data transmission mode, which is centered on Web servers. If a user finds that the CDN cache hit rate is low while using the CDN, the possible reasons are. (Number of correct answers: 3)
- A . When websites have low access traffic and the files are not popular enough, the CDN will receive fewer requests and result in lower cache hit rate.
- B . If the cache configuration is inappropriate (ex. overly short Cache Expiry Time for popular files), this may result in frequent back-to-source operations.
- C . Insufficient bandwidth was selected when enabling the CDN service, making the service capacity reaches the limit.
- D . If the origin site has a largo number of dynamic resources or mostly non-cashback content, this can also lead to frequent back-to-source operations.
- E . Tho HTTP Header setting may cause the cache to fail. In this case, users must check the origin site’s “Cacho-Control” and “Expires” settings.
In Auto Scaling, the cool-down time of a scaling group refers to the lockout period after a scaling activity has been executed successfully.
Which of the following statements about cool down time are true? (Number of correct answers: 2)
- A . During the cool-down time, only the scaling activities in the same scaling group are locked.
- B . You can’t skip a scaling group’s cool-down time period anyway right after a scaling activity is just finished.
- C . When multiple ECS instances are added or removed from a scaling group, the cool-down time begins only when the last instance has been added or removed from the scaling group.
- D . During the cool-down time of a scaling group, only the alarms from CloudMonitor can bypass the cool-down time and trigger scaling activities, whereas others will still subject to the cool-down time, such as the manually triggered scaling activities.
A user builds an ECS + SLB -t RDS business application architecture on the cloud, and uses Auto Scaling to flexibly scale-in and scale out ECS instances. For business reasons, you need to use Apsara DB for Redis as a cache for hot data storage to ensure high-speed data access for applications. However, the Auto Scaling Scaling Group cannot be associated with a Redis instance directly, you need to manually configure ECS instances to be added to or removed from the Redis whitelist, which is time-consuming, laborious and inefficient.
If you are an Alibaba Cloud architect, which 2 Auto Scaling and OOS features would you recommend, in order to automatically add and remove instances from the Redis whitelist?
- A . Auto-Scaling lifecycle hooks
- B . OOS Template
- C . MNS
- D . Instance launch template
To connect VPC with your traditional IDC. Alibaba Cloud currently supports the following methods: ________________ (Number of correct answers: 2)
- A . VPN Gateway
- B . HTTP agent
- C . Connection through a stopping stone
- D . Leased line connection
Which of the following database engines are compatible with RDS? (Number of correct answers: 3)
- A . MySQL
- B . PostgreSQL
- C . SQL Server
- D . PPAS
- E . Sybase
Which of the following scenarios can be done using Alibaba Cloud Express Connection? (Number of correct answers: 2)
- A . Intranet communication between two VPCs under the same account in the same region
- B . Intranet communication between two VPCs in different accounts and different CIDR Blocks
- C . Intranet communication between VPCs and Smart Access Gateway in customers different branch offices
- D . Intranet communication between a VPC and servers in an external IDC
Auto Scaling is a management service that can automatically adjust elastic computing resources based on your business needs and policies It supports adding an existing ECS instance into the scaling group but imposes certain requirements on instance region In this case, which of the following statements is true?
- A . The instance and the scaling group must be in the same region and zone.
- B . The instance and the scaling group must be in the same region but not necessarily the same zone.
- C . Each scaling group can span up to two regions. After adding the ECS instance, the number of regions of all the ECS instances in the scaling group must be no greater than two.
- D . The instance and the scaling group can be in different regions and zones.
