Q41. While creating a network in the VPC, which of the following is true of a NAT device?

A. You have to administer the NAT Gateway Service provided by AWS.

B. You can choose to use any of the three kinds of NAT devices offered by AWS for special purposes.

C. You can use a NAT device to enable instances in a private subnet to connect to the Internet.

D. You are recommended to use AWS NAT instances over NAT gateways, as the instances provide better availability and bandwidth.

Answer:

Explanation:

You can use a NAT device to enable instances in a private subnet to connect to the Internet (for example, for software updates) or other AWS services, but prevent the Internet from initiating connections with the instances. AWS offers two kinds of NAT devices u a NAT gateway or a NAT instance. We recommend NAT gateways, as they provide better availability and bandwidth over NAT instances. The NAT Gateway service is also a managed service that does not require your administration efforts. A NAT instance is launched from a NAT AM. You can choose to use a NAT instance for special purposes.

Answer: B


Q43. A friend wants you to set up a small BitTorrent storage area for him on Amazon S3. You tell him it is highly unlikely that AWS would allow such a thing in their infrastructure. However you decide to investigate. Which of the following statements best describes using BitTorrent with Amazon S3?

A. Amazon S3 does not support the BitTorrent protocol because it is used for pirated software.

B. You can use the BitTorrent protocol but only for objects that are less than 100 GB in size.

C. You can use the BitTorrent protocol but you need to ask AWS for specific permissions first.

D. You can use the BitTorrent protocol but only for objects that are less than 5 GB in size. 

Answer: D

Explanation:

BitTorrent is an open, peer-to-peer protocol for distributing files. You can use the BitTorrent protocol to retrieve any publicly-accessible object in Amazon S3.

Amazon S3 supports the BitTorrent protocol so that developers can save costs when distributing content at high scale. Amazon S3 is useful for simple, reliable storage of any data. The default distribution mechanism for Amazon S3 data is via client/server download. In client/server distribution, the entire object is transferred point-to-point from Amazon S3 to every authorized user who requests that object. While client/server delivery is appropriate for a wide variety of use cases, it is not optimal for everybody. Specifically, the costs of client/server distribution increase linearly as the number of users downloading objects increases. This can make it expensive to distribute popular objects.

BitTorrent addresses this problem by recruiting the very clients that are downloading the object as distributors themselves: Each client downloads some pieces of the object from Amazon S3 and some from other clients, while simultaneously uploading pieces of the same object to other interested "peers." The benefit for publishers is that for large, popular files the amount of data actually supplied by Amazon S3 can be substantially lower than what it would have been sewing the same clients via client/server download. Less data transferred means lower costs for the publisher of the object.

Q44. Having just set up your first Amazon Virtual Private Cloud (Amazon VPC) network, which defined a default network interface, you decide that you need to create and attach an additional network interface, known as an elastic network interface (ENI) to one of your instances. Which of the following statements is true regarding attaching network interfaces to your instances in your VPC?

A. You can attach 5 EN|s per instance type.

B. You can attach as many ENIs as you want.

C. The number of ENIs you can attach varies by instance type.

D. You can attach 100 ENIs total regardless of instance type. 

Answer: C

Explanation:

Each instance in your VPC has a default network interface that is assigned a private IP address from the   IP address range of your VPC. You can create and attach an additional network interface, known as an elastic network interface (ENI), to any instance in your VPC. The number of EN|s you can attach varies by instance type.


Q45. An Elastic IP address (EIP) is a static IP address designed for dynamic cloud computing. With an EIP, you can mask the failure of an instance or software by rapidly remapping the address to another instance in your account. Your EIP is associated with your AWS account, not a particular EC2 instance, and it  remains associated with your account until you choose to explicitly release it. By default how many EIPs  is each AWS account limited to on a per region basis?

A. 1

B. 5

C. Unlimited

D. 10

Answer:

Explanation:

By default, all AWS accounts are limited to 5 Elastic IP addresses per region for each AWS account, because public (IPv4) Internet addresses are a scarce public resource. AWS strongly encourages you to use an EIP primarily for load balancing use cases, and use DNS hostnames for all other inter-node communication.

If you feel your architecture warrants additional EIPs, you would need to complete the Amazon EC2 Elastic IP Address Request Form and give reasons as to your need for additional addresses. Reference:

Q46. Which of the following is true of Amazon EC2 security group?

A. You can modify the outbound rules for EC2-Classic.

B. You can modify the rules for a security group only if the security group controls the traffic for just one instance.

C. You can modify the rules for a security group only when a new instance is created.

D. You can modify the rules for a security group at any time. 

Answer: D

Explanation:

A security group acts as a virtual firewall that controls the traffic for one or more instances. When you launch an instance, you associate one or more security groups with the instance. You add rules to each security group that allow traffic to or from its associated instances. You can modify the rules for a security group at any time; the new rules are automatically applied to all instances that are associated with the security group.

Q47. What is the Reduced Redundancy option in Amazon 53?

A. Less redundancy for a lower cost.

B. It doesn't exist in Amazon 53, but in Amazon EBS.

C. It allows you to destroy any copy of your files outside a specific jurisdiction.

D. It doesn't exist at all 

Answer: A


Q48. Which of the following statements is NOT true about using Elastic IP Address (EIP) in EC2-Classic and EC2-VPC platforms?

A. In the EC2-VPC platform, the Elastic IP Address (EIP) does not remain associated with the instance when you stop it.

B. In the EC2-Classic platform, stopping the instance disassociates the Elastic IP Address (EIP) from it.

C. In the EC2-VPC platform, if you have attached a second network interface to an instance, when you disassociate the Elastic IP Address (EIP) from that instance, a new public IP address is not assigned to the instance automatically; you'II have to associate an EIP with it manually.

D. In the EC2-Classic platform, if you disassociate an Elastic IP Address (EIP) from the instance, the instance is automatically assigned a new public IP address within a few minutes.

Answer:

Explanation:

In the EC2-Classic platform, when you associate an Elastic IP Address (EIP) with an instance, the instance's current public IP address is released to the EC2-Classic public IP address pool. If you disassociate an EIP from the instance, the instance is automatically assigned a new public IP address within a few minutes. In addition, stopping the instance also disassociates the EIP from it.

But in the EC2-VPC platform, when you associate an EIP with an instance in a default Virtual Private Cloud (VPC), or an instance in which you assigned a public IP to the eth0 network interface during launch, its current public IP address is released to the EC2-VPC public IP address pool. If you disassociate an

EIP from the instance, the instance is automatically assigned a new public IP address within a few minutes. However, if you have attached a second network interface to the instance, the instance is not automatically assigned a new public IP address; you'II have to associate an EIP with it manually. The EIP remains associated with the instance when you stop it.

Q50. You need to create a JSON-formatted text file for AWS CIoudFormation. This is your first template and the only thing you know is that the templates include several major sections but there is only one that is  required for it to work. What is the only section required?

A. Mappings

B. Outputs

C. Resources

D. Conditions 

Answer: C

Explanation:

AWS CIoudFormation is a service that helps you model and set up your Amazon Web Services resources so that you can spend less time managing those resources and more time focusing on your applications that run in AWS. You create a template that describes all the AWS resources that you want (like Amazon EC2 instances or Amazon RDS DB instances), and AWS CIoudFormation takes care of provisioning and configuring those resources for you.

A template is a JSON-formatted text file that describes your AWS infrastructure. Templates include several major sections.

The Resources section is the only section that is required.

The first character in the template must be an open brace ({), and the last character must be a closed brace (}). The following template fragment shows the template structure and sections.
