Question #61
Which AWS service gives users the ability to provision a dedicated and private network connection
from their internal
network to AWS?
- A . AWS CloudHSM
- B . AWS Direct Connect
- C . AWS VPN
- D . Amazon Connect
Correct Answer: B
B
Explanation:
AWS Direct Connect gives users the ability to provision a dedicated and private network connection from their internal network to AWS. AWS Direct Connect links the user’s internal network to an AWSDirect Connect location over a standard Ethernet fiber-optic cable. One end of the cable is connected to the user’s router, the other to an AWS Direct Connect router. With this connection in place, the user can create virtual interfaces directly to the AWS cloud and Amazon Virtual Private Cloud (Amazon VPC), bypassing internet service providers in the network path2.

Question #64
Which pricing model will interrupt a running Amazon EC2 instance if capacity becomes temporarily unavailable?
- A . On-Demand Instances
- B . Standard Reserved Instances
- C . Spot Instances
- D . Convertible Reserved Instances
Correct Answer: C
C
Explanation:
Spot Instances are a type of EC2 instance that let you bid on unused compute capacity, which AWS offers at a discount of up to 90% compared to On-Demand prices1. Spot Instances are suitable for fault-tolerant, stateless, or flexible applications that can handle interruptions2. Spot Instances can be interrupted with a two-minute warning when EC2 needs the capacity back3. The other options are not pricing models that will interrupt a running EC2 instance if capacity becomes temporarily unavailable

Question #67
Which AWS service or feature captures information about the network traffic to and from an Amazon EC2 instance?
- A . VPC Reachability Analyzer
- B . Amazon Athena
- C . VPC Flow Logs
- D . AWS X-Ray
Correct Answer: C
C
Explanation:
The correct answer is C because VPC Flow Logs is an AWS service or feature that captures information about the network traffic to and from an Amazon EC2 instance. VPC Flow Logs is a feature that enables customers to capture information about the IP traffic going to and from network interfaces in their VPC. VPC Flow Logs can help customers to monitor and troubleshoot connectivity issues, such as traffic not reaching an instance or traffic being rejected by a security group. The other options are incorrect because they are not AWS services or features that capture information about the network traffic to and from an Amazon EC2 instance. VPC Reachability Analyzer is an AWS service or feature that enables customers to perform connectivity testing between resources in their VPC and identify configuration issues that prevent connectivity. Amazon Athena is an AWS service that enables customers to query data stored in Amazon S3 using standard SQL. AWS X-Ray is an AWS service that enables customers to analyze and debug distributed applications, such as those built using a microservices architecture.

Question #68
A company is moving an on-premises data center to the AWS Cloud. The company must migrate 50 petabytes of file storage data to AWS with the least possible operational overhead.
Which AWS service or resource should the company use to meet these requirements?
- A . AWS Snowmobile
- B . AWS Snowball Edge
- C . AWS Data Exchange
- D . AWS Database Migration Service (AWS DMS)
Correct Answer: A
A
Explanation:
The AWS service that the company should use to meet these requirements is A. AWS Snowmobile. AWS Snowmobile is a service that allows you to migrate large amounts of data to AWS using a 45-foot long ruggedized shipping container that can store up to 100 petabytes of data. AWS Snowmobile is designed for situations where you need to move massive amounts of data to the cloud in a fast, secure, and cost-effective way.AWS Snowmobile has the least possible operational overhead because it eliminates the need to buy, configure, or manage hundreds or thousands of storage devices12. AWS Snowball Edge is a service that allows you to migrate data to AWS using a physical device that can store up to 80 terabytes of data and has compute and storage capabilities to run applications on the device. AWS Snowball Edge is suitable for situations where you have limited or intermittent network connectivity, or where bandwidth costs are high.However, AWS Snowball Edge has more operational overhead than AWS Snowmobile because you need to request multiple devices and transfer your data onto them using the client3.
AWS Data Exchange is a service that allows you to find, subscribe to, and use third-party data in the cloud.AWS Data Exchange is not a data migration service, but rather a data marketplace that enables data providers and data consumers to exchange data sets securely and efficiently4.
AWS Database Migration Service (AWS DMS) is a service that helps migrate databases to AWS.AWS DMS does not migrate file storage data, but rather supports various database platforms and engines as sources and targets5.

Question #69
An ecommerce company wants to design a highly available application that will be hosted on multiple Amazon EC2 instances.
How should the company deploy the EC2 instances to meet these requirements?
- A . Across multiple edge locations
- B . Across multiple VPCs
- C . Across multiple Availability Zones
- D . Across multiple AWS accounts
Correct Answer: C
C
Explanation:
The company should deploy the EC2 instances across multiple Availability Zones to design a highly available application. Availability Zones are isolated locations within an AWS Region that are engineered to be fault-tolerant and operate independently of each other. By deploying the EC2 instances across multiple Availability Zones, the company can ensure that their application can withstand the failure of an entire Availability Zone and continue to operate with minimal disruption. Deploying the EC2 instances across multiple edge locations, VPCs, or AWS accounts will not provide the same level of availability and fault tolerance as Availability Zones. Edge locations are part of the Amazon CloudFront service, which is a content delivery network (CDN) that caches and serves webcontent to users. VPCs are virtual networks that isolate the AWS resources within an AWS Region. AWS accounts are the primary units of ownership and access control for AWS resources12
