Amazon AWS Certified Solutions Architect - Professional AWS-Solutions-Architect-Professional Prüfungsfragen mit Lösungen (Q57-Q62):

57. Frage
A global manufacturing company plans to migrate the majority of its applications to AWS. However, the company is concerned about applications that need to remain within a specific country or in the company's central on-premises data center because of data regulatory requirements or requirements for latency of single-digit milliseconds. The company also is concerned about the applications that it hosts in some of its factory sites, where limited network infrastructure exists.
The company wants a consistent developer experience so that its developers can build applications once and deploy on premises, in the cloud, or in a hybrid architecture.
The developers must be able to use the same tools, APIs, and services that are familiar to them.
Which solution will provide a consistent hybrid experience to meet these requirements?

A. Migrate the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds to an AWS Local Zone. Deploy AWS Wavelength to host the workloads in the factory sites.
B. Use AWS Snowball Edge Storage Optimized devices for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Retain the devices on premises.
Deploy AWS Wavelength to host the workloads in the factory sites.
C. Install AWS Outposts for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds. Use AWS Snowball Edge Compute Optimized devices to host the workloads in the factory sites.
D. Migrate all applications to the closest AWS Region that is compliant. Set up an AWS Direct Connect connection between the central on-premises data center and AWS. Deploy a Direct Connect gateway.

Antwort: C

Begründung:
Installing AWS Outposts for the applications that have data regulatory requirements or requirements for latency of single-digit milliseconds will provide a fully managed service that extends AWS infrastructure, services, APIs, and tools to customer premises1. AWS Outposts allows customers to run some AWS services locally and connect to a broad range of services available in the local AWS Region1. Using AWS Snowball Edge Compute Optimized devices to host the workloads in the factory sites will provide local compute and storage resources for locations with limited network infrastructure2. AWS Snowball Edge devices can run Amazon EC2 instances and AWS Lambda functions locally and sync data with AWS when network connectivity is available2.

58. Frage
Which of the following are characteristics of Amazon VPC subnets? Choose 2 answers

A. Instances in a private subnet can communicate with the Internet only if they have an Elastic IP.
B. Each subnet spans at least 2 Availability Zones to provide a high-availability environment.
C. By default, all subnets can route between each other, whether they are private or public.
D. CIDR block mask of /25 is the smallest range supported.
E. Each subnet maps to a single Availability Zone.

Antwort: A,B

59. Frage
A company has a standard three-tier architecture using two Availability Zones. During the company's off season, users report that the website is not working. The Solutions Architect finds that no changes have been made to the environment recently, the website is reachable, and it is possible to log in. However, when the Solutions Architect selects the "find a store near you" function, the maps provided on the site by a third-party RESTful API call do not work about 50% of the time after refreshing the page. The outbound API calls are made through Amazon EC2 NAT instances.
What is the MOST likely reason for this failure and how can it be mitigated in the future?

A. One of the NAT instances failed. Recommend replacing the EC2 NAT instances with a NAT gateway.
B. The fault is in the third-party environment. Contact the third party that provides the maps and request a fix that will provide better uptime.
C. One NAT instance has become overloaded. Replace both EC2 NAT instances with a larger-sized instance and make sure to account for growth when making the new instance size.
D. The network ACL for one subnet is blocking outbound web traffic. Open the network ACL and prevent administration from making future changes through IAM.

Antwort: D

60. Frage
An organization is setting up RDS for their applications. The organization wants to secure RDS access
with VPC. Which of the following options is not required while designing the RDS with VPC?

A. The organization should keep minimum of one IP address in each subnet reserved for RDS failover.
B. If the organization is connecting RDS from the internet it must enable the VPC attributes DNS
hostnames and DNS resolution.
C. The organization must create a subnet group with VPC using more than one subnet which are a part of
separate AZs.
D. The organization must create a subnet group with public and private subnets. Both the subnets can be
in the same or separate AZ.

Antwort: D

Begründung:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user's AWS account. It enables the
user to launch AWS resources, such as RDS into a virtual network that the user has defined. Subnets are
segments of a VPC's IP address range that the user can designate to a group of VPC resources based on
security and operational needs. A DB subnet group is a collection of subnets (generally private) that the
user can create in a VPC and assign to the RDS DB instances. A DB subnet group allows the user to
specify a particular VPC when creating the DB instances.
Each DB subnet group should have subnets in at least two Availability Zones in a given region. If the RDS
instance is required to be accessible from the internet the organization must enable the VPC attributes,
DNS hostnames and DNS resolution. For each RDS DB instance that the user runs in a VPC, he should
reserve at least one address in each subnet in the DB subnet group for use by Amazon RDS for recovery
actions.
