QUESTION 311
A company is launching a static website using the zone apex (mycompany com). The company wants to use Amazon Route 53 for DNS.
Which steps should the company perform to implement a scalable and cost-effective solution? (Select TWO )
A. A Host the website on an Amazon EC2 instance with ELB and Auto Scaling, and map a Route 53 alias record to the ELB endpoint
B. Host the website using AWS Elastic Beanstalk and map a Route 53 alias record to the Beanstalk stack.
C. Host the website on an Amazon EC2 instance, and map a Route alias record to the public IP address of the Amazon
D. Serve the website from an Amazon S3 bucket and map a Route 53 alias record to the website endpoint
E. Create a Route 53 hosted zone, and set the NS record of the domain to use Route 53 name servers.

Answer: DE，静态网页肯定是在S3上，但是E为什么是对的？

 

QUESTION 314
A Solutions Architect plans to migrate a load balancer tier from a data center to AWS. Several websites have multiple domains that require secure load balancing. The Architect decides to use Elastic Load Balancing Application Load Balancers.What is the MOST efficient method for achieving secure communication?
A. Create a wildcard certificate and upload it to the Application Load Balancer
B. Create an SNI certificate and upload it to the Application Load Balancer
C. Create a secondary proxy server to terminate SSL traffic before the traffic reaches the Application Load Balancer
D. Let a third-party Certificate Manager manage certificates required to all domains and upload them to the Application Load Balancer

Answer: B 似乎也只能选B，AD明显不可能，也没有听说过C中secondary proxy server的说法，但是不知道B为什么是对的？

 

QUESTION 327
A Solution Architect is creating a serverless web application that must access mapping data in hundreds of data files, each containing approximately 30 KB
of data. The storage required is expected to grow to hundreds of terabytes.Which storage solution is most cost-effective, yet still meets the requirements for
this use case?
A. Amazon EFS
B. Amazon EBS Cold HDD (sc1)
C. Amazon S3 Standard

D. Amazon DynamoDB

Answer: 是因为cost-effective所以选D吗？

 

谢谢老师和同学！

Q311. E是因为在使用Route 53之前，先需要把域名管理权限托管到AWS上，因此需要用E来改NS服务器，这样Route53才能对你的域名mycompany com做管理。

Q314. 因为题目说有很多个域名，而且需要绑定到ELB上，SNI可以做到多域名的ELB和TLS证书

Q327. 是因为Serverless所以选D喔，DynamoDB其实并没有太多价格优势

最后，挨踢茶馆近期上线了问答模块，下次提问可以试试哈。每一个题目做一个问题。

Q327,题目中有提到是data files,数据的存储在这里只有Dynamo DB是数据存储，答案C 的S3是对象存储。
