To support critical production workloads that require maximum resiliency, a company wants to configure network connections between its Amazon VPC and the on-premises infrastructure. The company needs AWS Direct Connect connections with speeds greater than 1 Gbps.
As a solutions architect, which of the following will you suggest as the best architecture for this requirement?
Opt for at least two Direct Connect connections terminating on different
devices at a single Direct Connect location
Opt for one Direct Connect connection at each of the multiple Direct
Connect locations
Use AWS Managed VPN as a backup for AWS Direct Connect
connections to ensure maximum resiliency
Opt for two separate Direct Connect connections terminating on
separate devices in more than one Direct Connect location
A company has noticed several provisioned throughput exceptions on its DynamoDB database due to major spikes in the writes to the database. The development team wants to decouple the application layer from the database layer and dedicate a worker process to writing the data to DynamoDB.
Which middleware do you recommend on using that can scale infinitely and meet these requirements in the most cost effective way?
Kinesis Data Streams
DynamoDB DAX
Amazon Simple Notification Service (SNS)
Amazon Simple Queue Service (SQS)
The DevOps team at a major financial services company uses Multi-Availability Zone (Multi-AZ) deployment for its MySQL RDS database in order to automate its database replication and augment data durability. The DevOps team has scheduled a maintenance window for a database engine level upgrade for the coming weekend.
Which of the following is the correct outcome during the maintenance window?
Any database engine level upgrade for an RDS DB instance with
Multi-AZ deployment triggers both the primary and standby DB
instances to be upgraded at the same time. This causes
downtime until the upgrade is complete
Any database engine level upgrade for an RDS DB instance with Multi-AZ
deployment triggers both the primary and standby DB instances tobe
upgraded at the same time. However, this does not cause any downtime
until the upgrade is complete |
Any database engine level upgrade for an RDS DB instance
with Multi-AZ deployment triggers the standby DB instance to
be upgraded which is then followed by the upgrade of the
primary DB instance. This does not cause any downtime for the
duration of the upgrade
Any database engine level upgrade for an RDS DB instance with Multi-AZ
deployment triggers the primary DB instance to be upgraded which is
then followed by the upgrade of the standby DB instance. This does not
cause any downtime for the duration of the upgrade
A data analytics company is running a proprietary database on an EC2 instance using EBS volumes. The database is heavily I/O bound. As a solutions architect, which of the following RAID configurations would you recommend improving the I/O performance?
Both RAID 0 and RAID 1 provide equally good 1/0 performance
Amazon EBS does not support the standard RAID
configurations
Use RAID 1 when 1/0 performance is more important than fault tolerance
Use RAID 0 when 1/0 performance is more important than fault
tolerance
An e-commerce company uses RDS MySQL DB to store the data. The analytics department at the company runs its reports on the same DB. The engineering team has noticed sluggish performance on the DB when the analytics reporting process is in progress.
As an AWS Certified Solutions Architect Associate, which of the following would you suggest as the MOST cost-optimal solution to improve the performance?
Create a standby instance in a multi-AZ configuration with the same
compute capacity and the same storage capacity as the primary. Point the
reporting queries to run against the standby instance
Create a standby instance in a multi-AZ configuration with half compute
capacity and half storage capacity as the primary. Point the reporting
queries to run against the standby instance
Create aread-replica with half compute capacity and halfstorage capacity as the primary. Point the reporting queries torun against the read replica
Create a read-replica with the same compute capacity and the
same storage capacity as the primary. Point the reporting
queries to run against the read replica
A Big Data company wants to optimize its daily Extract-Transform-Load (ETL) process that migrates and transforms data from its S3 based data lake to a Redshift cluster. The team wants to manage this daily job in a serverless environment.
Which AWS service is the best fit to manage this process without the need to configure or manage the underlying compute resources?
Amazon EMR
AWS Glue
AWS Database Migration Service (DMS)
AWS Data Pipeline
