Rather than use S3, store the images inside a BLOB on RDS with Multi-AZ configured for redundancy.ī. What is the most commercially feasible method to store the processed images?Ī. Users will typically download the image once (immediately), and then never download the image again. These EC2 instances will then turn the picture in to a cartoon and will then need to store the processed job somewhere. The application then passes a job to AWS SQS and a fleet of EC2 instances poll the queue to receive new processing jobs. Customers will log on to the site, upload an image which is stored in S3. You are designing a site for a new start up which generates cartoon images for people automatically. For more information on I2 instances, please visit the link: They are well suited for the following scenarios: NoSQL databases (for example, Cassandra and MongoDB) Clustered databases online transaction processing (OLTP) systems. I2 instances are optimized to deliver tens of thousands of low-latency, random I/O operations per second (IOPS) to applications. Which class of instances from the below list should they choose from ? There is a requirement to host a NoSQL database with a need for low latency. For more information on EBS snapshots, please visit the link. You can easily create a snapshot from a volume while the instance is running and the volume is in use. Which of the below are incremental backups of your EBS volumes? Choose one answer from the options given below. This is clearly given in the aws documentation For more information on Spot Instances, please visit the link – Which of the below instances is used normally for massive parallel computations? SkillCertPro assures 100% pass guarantee in first attempt. You will get life time access and life time free updates SkillCertPro updates exam questions every 2 weeks. It is recommended to score above 85% in SkillCertPro exams before attempting a real exam. SkillCertPro offers detailed explanations to each question which helps to understand the concepts better. You can use groups to specify permissions for a collection of users, which can make those permissions easier to manage for those users An IAM role is very similar to a user, in that it is an identity with permission policies that determine what the identity can and cannot do in AWS For more information on IAM entities, please visit the url The IAM user represents the person or service who uses the IAM user to interact with AWS An IAM group is a collection of IAM users. In IAM, what is the representation of a person or service?Īn IAM user is an entity that you create in AWS. This is clearly given in the aws documentation For more information on Cloudformation templates, please visit the url Which of the following is mandatory when defining a cloudformation template? In order for the EC2 or ELBs to be accessible from internet, we would need to configure the route table for public subnet to route traffic to VPC internet gateway.įor information on VPC Route Tables and VPC Internet Gateway, please visit the link: No internet gateway is attached to the VPC. No elastic IP is assigned to web servers.ĭ. Route table for public subnet is not configured to route to VPC internet gateway.Ĭ. Web server must be launched inside public subnet and not private subnet.ī. Yet, you are still unable to access your web application through the internet, which of the following would likely the cause of this?Ī. You have launched two web servers in private subnet and one ELB (internet facing) in public subnet in your VPC. With Windows instances, you use a key pair to obtain the administrator password and then log in using RDP.įor more information on key pairs, please visit the below url įor DynamoDB, what are the scenario’s in which you would want to enable Cross-region replication?įrom the AWS Documentation, it clearly states the reason for why you would want to enable Cross-Region Replication.įor more information on DynamoDB, please visit the url Linux instances have no password, and you use a key pair to log in using SSH. To log in to your instance, you must create a key pair, specify the name of the key pair when you launch the instance, and provide the private key when you connect to the instance. The public and private keys are known as a key pair. Public–key cryptography uses a public key to encrypt a piece of data, such as a password, then the recipient uses the private key to decrypt the data. In AWS what is used for encrypting and decrypting login information to EC2 instances.Īmazon EC2 uses public–key cryptography to encrypt and decrypt login information.
