NO.42 When using Alibaba Cloud SLB to forward layer 7 (HTTP) service requests. SLB will replace the IP address in the HTTP header file to forward requests.
Therefore the source IP address that can be seen on the backend ECS instance is the IP address of SLB instead of the clients real IP address.

True

False

NO.43 The daily PV volume of a community website is as high as 20 million. The applications of the website are deployed on ECS instances while logs are stored on the data disks of a single ECS instance.
Now, the website wants to extend the log retention period to 24 months and ensure that logs can be quickly downloaded when needed. The current data disks they have can only help retain three months of logs In this case, ________ is the ideal solution for solving the log retention issue.

CDN

Container Service

OSS

ApsaraDB for RDS

NO.44 Names of the files in each OSS bucket must be unique Also, they can be renamed.

True

False

NO.45 Before data communication is setup, the security groups match the security group rules one by one to query whether to allow access requests Assume that the user has created two security group rules 1 and 2 The protocol type, port range, authorization type, and authorization object of the two security group rules are the same. The difference is that Rule 1 is a denial policy, rule 2 is an allowed policy, so the following statement is correct_______ (Number of correct answers 2)

If rule 1 and rule 2 have the same priority, the rule of the denial policy takes effect first, and the rule of the allowed policy does not take effect

If rule 1 and rule 2 have the same priority, the rule of the allowed policy takes effect first, and the rule that of the denial policy does not take effect.

If rule 1 and rule 2 have different priorities, the rule with a small priority number takes effect

If rule 1 and rule 2 have different priorities, the rule with a large priority number takes effect.

NO.46 When using Alibaba Cloud SLB. you can set different weights for backend ECS instances The higher the weight of a backend ECS instance the more load will be assigned to it An SLB instance has 5 ECS instances in the backend server pool, all of which are healthy Among these 5 ECS instances, the weight of ecs_inst1 is set to 100. Which of the following statements is correct?

Based on request level parameters of external requests, all requests with a request level parameter of 100 will be transferred to ecs_inst1

Based on SLB’s working mechanism, approximately 20% of loads will be assigned to ecs_inst1

We do not know the weight settings of the remaining 4 ECS instances, so we cannot tell what would happen

100% of loads will be assigned to ecs__inst1, and the remaining 4 ECS instances will stay idle

NO.47 Which of the following statements is most accurate about the Data Transmission Service (DTS) database migration function?

Supports database schema replication between instances.

Supports warning when source and destination has some unresolved conflict found.

Supports all of the above functions.

Supports migrating MySQL databases from external sources.

NO.48 Alibaba Cloud Object Storage Service (OSS) is a cloud storage service that features massive capacity, outstanding security, low costs, and high reliability. In an OSS bucket, all elements are stored as________.

Hashes

Keys

Objects

Stubs

NO.49 A company launched its online service just a year ago. It uses five ECS instances and does not have a full-time system administrator Over the last six months, the company’s system has encountered various security problems Several high-risk vulnerabilities were exploited by hackers, leading to leakage of the company’s confidential dat a. Which of the following Alibaba Cloud products can be used to quickly resolve this problem?

Managed Security Service

Cloud Firewall

Anti-DDoS Pro Service

Security Center

NO.50 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’?

NO.51 Which of the following scenarios can be done using Alibaba Cloud Express Connection? (Number of correct answers: 2)

Intranet communication between VPCs and Smart Access Gateway in customers different branch offices

Intranet communication between a VPC and servers in an external IDC

Intranet communication between two VPCs in different accounts and different CIDR Blocks

Intranet communication between two VPCs under the same account in the same region

NO.52 The difference between public and private Server Load Balancers (SLBs) is that private SLBs connect to their backend ECS instances using the private network (Intranet) while public SLBs connect to their backend ECS instances using the public network (Internet).

True

False

NO.53 You are designing a solution for a startup company, the proposed solution is like this You suggest they use ECS instances to process requests from mobile App clients, and use SLB to distribute data traffic and ensure the load across each backend ECS instance is balanced.
Moreover to deal with volatile fluctuations in business volume (page views are much higher on the weekends), you also suggest they use Auto Scaling to dynamically increase or reduce computing resources.
The company is satisfied with the solution you proposed. However, they have one concern that when removing an idle instance from the scaling group: if Auto Scaling shuts the instance down directly, the service running on that instance will be abruptly terminated, resulting in poor user experience.
In order to eliminate your customer’s concern, which of the following solutions should you recommend them?

Find the ECS instance that is going to be removed from the backend server pool of the SLB instancer and automatically set the weight of this ECS instance to 0. This instance will not be assigned with new requests, and will be automatically removed from the backend server pool after existing tasks are completed.

First, insert a script into the image for creating the ECS instance Second, make the script run automatically when the operating system in this ECS instances is about to shut down. This script contains the processing logic that can ensure the instance finish all the remaining tasks before shutting down.

Find the ECS instance that is going to be removed from the backend server pool of the SLB instance, and manually remove this instance from the backend server pool Applications running on this ECS instance will normally return results, but this instance will not be assigned with new requests.

Use the Lifecycle Hook function embedded m Auto Scaling Define a suitable timeout and a web hook to do the necessary work before the instance is removed.

NO.54 RDS accounts can be used to connect with the databases created on a given RDS instance. Each account can be bound with multiple databases. Yet, the read/write permissions of each database can only be assigned to one RDS account

True

False

NO.55 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.

NO.56 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
