Multiple-Choice

You are maintaining a web application where content is stored in an S3 bucket and delivered by CloudFront. You need to ensure that only users who have authenticated via your company's authentication service can access the content. You decide to implement a signed URL solution.

Which of the following code snippets correctly generates a signed URL for AWS CloudFront content?

//javascript
const AWS = require('aws-sdk');
const cloudFront = new AWS.CloudFront();


const params = {
 DistributionId: 'E1A2B3C4D5E',
 PrivateKey: 'privateKey.pem',
 KeyPairId: 'APKAJCEOKRHC3XIVU5NA',
 Url: 'https://d111111abcdef8.cloudfront.net/my-object',
 Expires: 180 // time in seconds
};


cloudFront.getSignedUrl(params, function(err, data) {
 if (err) console.log(err);
 else console.log(data);
});

//javascript
const AWS = require('aws-sdk');
const cloudFront = new AWS.CloudFront.Signer('APKAJCEOKRHC3XIVU5NA', 'privateKey.pem');


const options = {
 url: 'https://d111111abcdef8.cloudfront.net/my-object',
 expires: Math.floor((new Date().getTime() / 1000) + 180) // Current time + 3 minutes (in Unix time)
};


cloudFront.getSignedUrl(options, function(err, url) {
 if (err) console.log(err);
 else console.log(url);
});

//javascript
const AWS = require('aws-sdk');
const cloudFront = new AWS.CloudFront();


const params = {
 Bucket: 'my-bucket',
 Key: 'my-object',
 Expires: 180,
 ACL: 'authenticated-read'
};


cloudFront.createPresignedPost(params, function(err, data) {
 if (err) console.log(err);
 else console.log(data);
});

//javascript
const AWS = require('aws-sdk');
const s3 = new AWS.S3();
const url = s3.getSignedUrl('getObject', {
 Bucket: 'my-bucket',
 Key: 'my-object',
 Expires: 180
});


console.log(url);
