A photo-sharing service stores pictures in Amazon Simple Storage Service (S3) and allows application sign-in using an opened connect-compatible identity provider. Which AWS Security Token Service approach to temporary access should you use for the Amazon S3 operations?

• A.SAML-based Identity Federation
• B.Web identity Federation
• C.AWS identity and Access Management roles
• D.Cross-Account Access

What is web identity federation?

• A.Use of an identity provider like Google or Facebook to exchange for temporary AWS security credentials.
• B.Use of an identity provider like Google or Facebook to become an AWS IAM User.
• C.Use of AWS STS Tokens to log in as a Google or Facebook user.
• D.Use of AWS IAM User tokens to log in as a Google or Facebook user.

Company A operates in Country X, Company A maintains a large dataset of historical purchase orders that contains personal data of their customers in the form of full names and telephone numbers. The dataset consists of 5 text files. 1TB each. Currently the dataset resides on- premises due to legal requirements of storing personal data in-country. The research and development department need to run a clustering algorithm on the dataset and wants to use Elastic Map Reduce service in the closes AWS region. Due to geographic distance the minimum latency between the on-premises system and the closet AWS region is 200 ms.
Which option allows Company A to do clustering in the AWS Cloud and meet the legal requirement of maintaining personal data in-country?

• A.Establishing a Direct Connect link between the on-premises system and the AWS region to reduce latency. Have the EMR cluster read the data directly from the on-premises storage system over Direct Connect.
• B.Encrypt the data files according to encryption standards of Country X and store them in AWS region in Amazon S3. Have the EMR cluster read the dataset using EMRFS.
• C.Use AWS Import/Export Snowball device to securely transfer the data to the AWS region and copy the files onto an EBS volume. Have the EMR cluster read the dataset using EMRFS.
• D.Anonymize the personal data portions of the dataset and transfer the data files into Amazon S3 in the AWS region. Have the EMR cluster read the dataset using EMRFS.

An online photo album app has a key design feature to support multiple screens (e.g, desktop, mobile phone, and tablet) with high-quality displays. Multiple versions of the image must be saved in different resolutions and layouts.
The image-processing Java program takes an average of five seconds per upload, depending on the image size and format. Each image upload captures the following image metadata: user, album, photo label, upload timestamp.
The app should support the following requirements:
Hundreds of user image uploads per second
Maximum image upload size of 10 MB
Maximum image metadata size of 1 KB
Image displayed in optimized resolution in all supported screens no later than one minute after image upload Which strategy should be used to meet these requirements?

• A.Write image and metadata to Amazon Kinesis. Use Amazon Elastic MapReduce (EMR) with Spark Streaming to run image processing and save the images output to Amazon S3 and metadata to app repository DB.
• B.Upload image with metadata to Amazon S3, use Lambda function to run the image processing and save the images output to Amazon S3 and metadata to the app repository DB.
• C.Write image and metadata RDS with BLOB data type. Use AWS Data Pipeline to run the image processing and save the image output to Amazon S3 and metadata to the app repository DB.
• D.Write images and metadata to Amazon Kinesis. Use a Kinesis Client Library (KCL) application to run the image processing and save the image output to Amazon S3 and metadata to the app repository DB.

When will you incur costs with an Elastic IP address (EIP)?

• A.Costs are incurred regardless of whether the EIP is associated with a running instance.
• B.When it is allocated and associated with a running instance.
• C.When it is allocated and associated with a stopped instance.
• D.When an EIP is allocated.
