Q49. A large enterprise wants to migrate the entire business system to Alibaba Cloud to save the overall IT procurement and O&M costs From the security aspect, the company requires that
1. Must support secured remote O&M because the administrator often takes business trips.
2. Networks between subsystems should be isolated because subsystems are independently used by different departments Which of the followings should be used together to meet the company’s requirements? (Number of correct answers: 3)

Enable the VPN on the bastion host (or directly use the VPN image on Alibaba Cloud Marketplace). The administrator uses VPN encrypted communication during O&M.

Build an independent ECS instance as the bastion host or remote logon and O&M, and authorize the bastion host to access ECS instances running other subsystems.

Use the security group function of the ECS instance, and respectively deploy ECS instances running different subsystems to independent security groups.

Create multiple ECS instances in the VPC to install subsystems of different departments- Allocate only Intranet IP addresses to all ECS instances, and deploy them in the same security groups.

Q50. A customer uses Alibaba Cloud Auto Scaling service and creates a scaling group He/she sets the “Minimum number of instances” to 2 and “Maximum number of instances” to 7.
After correctly configuring scaling settings, the customer adds a scaling rule “Add 6 ECS instances”, and creates a scheduled task based on this rule.
And then, the customer checks the scaling group and see it already contains 3 valid ECS instances, he/she then enables this scaling group immediately.
How many ECS instance will be added in the scaling group when the scheduled task is activated once’?

Q51. Alibaba Cloud CloudMonitor is a service that monitors Alibaba Cloud resources and Internet functions currently provided by CloudMonitor? (Number of correct answers: 3)

Site monitoring

Customized monitoring

Custom firewall

Operation auditing

Cloud service monitoring

Q52. If an administrator often needs to manage multiple ECS instances in an Alibaba Cloud VPC through the Internet Which of the following solutions can meet this need at low costs and without affecting system security.

None of these answers are correct.

Choose an ECS instance from VPC and make it as the bastion host And then, apply an EIP and bind it to this ECS instance. After that the administrator can manage other ECS instances through this bastion host.

Modify the VPC Security Group policy, to allow access from the Internet.

Bind an EIP to each of the ECS instances, and Jog on to each of these ECS instances to manage them.

Q53. If you need to accelerate a certain domain name (such as abc.com) via Alibaba Cloud Content Delivery Network (CDN), you must add it to “CDN Domain Name List” in the CDN service. After added successfully, you will get a CNAME address A Next, you need to modify domain name resolution and direct the domain name (such as abc.com) to CNAME address A.
Which of the following is a NOT correct description of modifying domain name resolution?

If your domain name (such as abc.com) is transferred to Alibaba Cloud in advance, and managed by the same Alibaba Cloud account, you can perform one-step resolution modification.

The CNAME address allocated to the domain name (such as abc.com) will point to an IP address. This IP address resolving mechanism is intelligently managed by Alibaba Cloud CDN system.

The DNS service provider used by the domain name (such as abc.com) must support intelligent resolution.

The DNS service provider used by the domain name (such as abc.com) can be companies other than Alibaba Cloud.

Q61. A video company uses SLB to distribute user requests to 20 ECS instances with the same configuration to response these requests. As the Spring Festival approaches, service traffic would double during holidays (based on past experience). Thus, you use Auto Scaling to elastically adjust computing resources. Since the services is online for many years, you have historic records that can help predict the upcoming service traffic and choose the scaling mode freely. In this scenario, which of the following options are feasible and with minimum operation efforts? (Number of correct answers: 2)

Cloud monitor and event-triggered task: Dynamically adds ECS instances during resource shortage and reduces ECS instances during idle hours by monitoring the CPU utilization rate and workload

Scheduled task: Increases the number of ECS instances to 40 on the first day of the holidays and reduce the number to 20 after the holidays.

Manual mode: Set the minimum number of instances to 40 on the first day of the holidays and change the number to 20 after the holidays.

Healthy check mode: Ensures that all the current ECS instances in scaling groups are working correctly to meet user access requests.
