EC2 Exam Questions And Answers (Verified And Updated) Which of the following statements are true about containers on A WS? (Choose 5) A. You can use the ECS Agent without needing to use ECS. B. ECS allows you to control the scheduling and placement of your containers and tasks. C. To use private images in ECS, you must refer to Docker images from ECR. D. ECR can be used t o store Docker images. E. You must use ECS to manage running Docker containers in AWS. F. You can have AWS manage Kubernetes for you. G. To be able to use ECS, you must use the ECS Agent. H. You can install and manage Kubernetes on AWS, yourself. - answer✔✔B,D,F,G,H You definitely can install Kubernetes, yourself. ECR is the EC2 Container Registry. ECS doesn't work without the ECS agent. You can customize a lot of things in ECS. Amazon El astic Container Service (Amazon ECS) is a highly scalable, high -performance container orchestration service that supports Docker containers and allows you to easily run and scale containerized applications on AWS. Amazon Elastic Container Registry (ECR) i s a fully -managed Docker container registry that makes it easy for developers to store, manage, and deploy Docker container images. ... Amazon ECR hosts your images in a highly available and scalable architecture, allowing you to reliably deploy containers for your applications. Kroonenburg 02 Which AWS CLI command should I use to create a snapshot of an EBS volume? A. aws ec2 create -snapshot B. aws ec2 new -snapshot C. aws ec2 fresh -snapshot D. aws ec2 deploy -snapshot - answer✔✔A Kroonenburg 03 Placem ent Groups can either be of the type 'Cluster' or 'Spread'. Choose options from below which are only specific to Spread Placement Groups. A. Spread placement groups require a name that is unique within your AWS account for the region B. A spread placemen t group is a logical grouping of instances within a single Availability Zone C. An instance can be launched in one placement group at a time and cannot span multiple placement groups. D. A spread placement group is a group of instances that are each plac ed on distinct underlying hardware - answer✔✔D There is only one answer that is specific to Spread Placement Groups, and that is the final option. Whilst some of these questions are correct for either Cluster Placement Groups only, or for both Cluster and Spread Placement Groups, the question stated th at only options specific to Spread Placement Groups should be chosen, which would rule out the first two options as they are true for both types of placement groups. The Logical grouping of instances within a single Availability Zone is only true of Cluste r Placement Groups and is also incorrect. You can launch or start instances in a placement group, which determines how instances are placed on underlying hardware. When you create a placement group, you specify one of the following strategies for the grou p: Cluster - clusters instances into a low -latency group in a single Availability Zone Partition - spreads instances across logical partitions, ensuring that instances in one partition do not share underlying hardware with instances in other partitions Spread - spreads instances across underlying hardware Kroonenburg 04 Can you attach an EBS volume to more than one EC2 instance at the same time? A. No. B. If that EC2 volume is part of an AMI. C. Yes. D. Depends on which region. - answer✔✔A Kroone nburg 05 If an Amazon EBS volume is an additional partition (not the root volume), can I detach it without stopping the instance? A. Yes, although it may take some time. B. No, you will need to stop the instance. - answer✔✔A Kroonenburg 06 Placement Groups can be created across 2 or more Availability Zones. A. False B. True - answer✔✔B Technically they are called Spread placement groups. Now you can have placement groups across different hardware and multiple AZs. Kroonenburg 07 The use of a placement group is ideal _______ A. Your fleet of EC2 instances requires high network throughput and low latency within a single availability zone. B. When you need to deploy EC2 instances that require high disk IO. C. When you need to distribute c ontent on a CDN network. D. Your fleet of EC2 Instances requires low latency and high network throughput across multiple availability zones. - answer✔✔A Placement Groups are primarally about keeping you compute resources within one network hop of each ot her on high speed rack switches. This is only helpful when tyou have compute loads with network loads that are either veryhigh or very sensitive to latency.
