A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group. They set the "Minimum number of instances" to 6 and the "Maximum number of instances" to 8. After correctly configuring scaling settings, the customer adds a scaling rule "Adjust to 10 ECS instances" and creates a scheduled task based on this rule. Then, the customer checks the scaling group and sees it already contains 6 valid ECS instances.
They then enable this scaling group immediately. How many ECS instances will be in the scaling group when the scheduled task is activated once?

質問 3

If you need to make the ECS instances under three VSwitches (inside the same Alibaba Cloud VPC) unable to access each other, while not affecting other Intranet connections in this VPC, what should you do?

（A）Create three Security Groups, each containing all ECS instances under these three VSwitches. First, configure each Security Group to allow access to all CIDR Blocks. Then, configure each Security Group to forbid access to the CIDR blocks of the other two VSwitches (with this rule given a lower priority than the previous rule).

（B）Create one Security Group containing all ECS instances under these three VSwitches. First, configure the Security Group to allow access to all CIDR Blocks. Then, configure the Security Group to forbid access to the CIDR blocks of the other two VSwitches (with this rule given higher priority than the previous rule).

（C）None of these answers are correct.

（D）Create three Security Groups, each containing all ECS instances under these three VSwitches. First, configure each Security Group to allow access to all CIDR Blocks. Then, configure each Security Group to forbid access to the CIDR blocks of the other two VSwitches (with this rule given higher priority than the previous rule).

質問 12

Alibaba Cloud Content Delivery Network (CDN) is a distributed network built on top of a base network with edge node server clusters distributed across various regions. If a user finds that the CDN cache hit rate is low, the possible reasons are ____________. (Choose three.)

（A）If the cache configuration is inappropriate (e.g., overly short Cache Expiry Time for popular files), this may result in frequent back-to-source operations.

（B）The HTTP Header setting may cause the cache to fail. In this case, users must check the origin site's
"Cache-Control" and "Expires" settings.

（C）If the origin site has a large number of dynamic resources or mostly non-cacheable content, this can also lead to frequent back-to-source operations.

（D）Insufficient bandwidth was selected when enabling the CDN service, making the service capacity reach its limit.

（E）When websites have low access traffic and the files are not popular enough, the CDN will receive fewer requests and result in a lower cache hit rate.
