ACP-Cloud1 Practice Questions

A.  

They can create an SLB instance in the VPC, and mount ECS instances within the VPC to this SLB instance. Then, use a jump server to receive external requests and direct these requests to SLB to forward them to backend ECS instances.

B.  

They can create an SLB instance with an Internet IP address, and mount ECS instances within the VPC to this SLB instance. The public SLB will be used to receive external requests. As a result, requests from the Internet will be transferred to backend ECS instances within the VP

C.  

C.  

They can create an SLB instance in the VPC, and mount ECS instances within the VPC to this SLB instance. Then, bind an EIP to the SLB, so that this SLB instance can receive requests from the Internet and assign these requests to the backend ECS instances.

D.  

They can create an SLB instance with an Internet IP address, and mount ECS instances within the VPC and servers of the traditional data center to this SLB instance. The public SLB will be used to receive external requests. As a result, requests from the Internet will be transferred to backend ECS instances within the VPC and servers of the traditional data center.

A.  

TRUE

B.  

FALSE

A.  

Stateless and horizontally scalable

B.  

Stateful

C.  

Stateless and idempotent

D.  

All data is locally stored on ECS instance disks

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.  

ECS instances in a VPC use security group firewalls for Layer 2 network access control.

D.  

The internal networks of different VPCs are completely isolated and can be interconnected through IP addresses mapped to the outside.

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 higher priority than the previous rule).

B.  

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).

C.  

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).
