ASSOCIATE PRACTICE EXAM 4
WITH ANSWERS
A social media company wants the capability to dynamically alter the size of
a geographic area from which traffic is routed to a specific server resource.
Which feature of Amazon Route 53 can help achieve this functionality? -
CORRECT-ANSWERSGeoproximity routing
A media company uses Amazon ElastiCache Redis to enhance the
performance of its Amazon RDS database layer. The company wants a robust
disaster recovery strategy for its caching layer that guarantees minimal
downtime as well as minimal data loss while ensuring good application
performance.
Which of the following solutions will you recommend to address the given
use-case? - CORRECT-ANSWERSOpt for Multi-AZ configuration with automatic
failover functionality to help mitigate failure
As an e-sport tournament hosting company, you have servers that need to
scale and be highly available. Therefore you have deployed an Elastic Load
Balancing (ELB) with an Auto Scaling group (ASG) across 3 Availability Zones
(AZs). When e-sport tournaments are running, the servers need to scale
quickly. And when tournaments are done, the servers can be idle. As a
general rule, you would like to be highly available, have the capacity to scale
and optimize your costs.
What do you recommend? (Select two) - CORRECT-ANSWERSSet the
minimum capacity to 2
Use Reserved Instances (RIs) for the minimum capacity
As a solutions architect, you have created a solution that utilizes an
Application Load Balancer with stickiness and an Auto Scaling Group (ASG).
The Auto Scaling Group spawns across 2 Availability Zones (AZs). AZ-A has 3
Amazon EC2 instances and AZ-B has 4 Amazon EC2 instances. The Auto
Scaling Group is about to go into a scale-in event due to the triggering of a
Amazon CloudWatch alarm.
,What will happen under the default Auto Scaling Group configuration? -
CORRECT-ANSWERSThe instance with the oldest launch configuration will be
terminated in AZ-B
An e-commerce company has copied 1 petabyte of data from its on-premises
data center to an Amazon S3 bucket in the us-west-1 Region using an AWS
Direct Connect link. The company now wants to set up a one-time copy of
the data to another Amazon S3 bucket in the us-east-1 Region. The on-
premises data center does not allow the use of AWS Snowball.
As a Solutions Architect, which of the following options can be used to
accomplish this goal? (Select two) - CORRECT-ANSWERSCopy data from the
source bucket to the destination bucket using the aws S3 sync command
Set up Amazon S3 batch replication to copy objects across Amazon S3
buckets in another Region using S3 console and then delete the replication
configuration
A retail company is using AWS Site-to-Site VPN connections for secure
connectivity to its AWS cloud resources from its on-premises data center.
Due to a surge in traffic across the VPN connections to the AWS cloud, users
are experiencing slower VPN connectivity.
Which of the following options will maximize the VPN throughput? -
CORRECT-ANSWERSCreate an AWS Transit Gateway with equal cost
multipath routing and add additional VPN tunnels
A company wants to adopt a hybrid cloud infrastructure where it uses some
AWS services such as Amazon S3 alongside its on-premises data center. The
company wants a dedicated private connection between the on-premise data
center and AWS. In case of failures though, the company needs to guarantee
uptime and is willing to use the public internet for an encrypted connection.
What do you recommend? (Select two) - CORRECT-ANSWERSUse AWS Direct
Connect connection as a primary connection
Use AWS Site-to-Site VPN as a backup connection
A company has grown from a small startup to an enterprise employing over
1000 people. As the team size has grown, the company has recently
observed some strange behavior, with Amazon S3 buckets settings being
changed regularly.
How can you figure out what's happening without restricting the rights of the
users? - CORRECT-ANSWERSUse AWS CloudTrail to analyze API calls
, Your company runs a web portal to match developers to clients who need
their help. As a solutions architect, you've designed the architecture of the
website to be fully serverless with Amazon API Gateway and AWS Lambda.
The backend uses Amazon DynamoDB table. You would like to automatically
congratulate your developers on important milestones, such as - their first
paid contract. All the contracts are stored in Amazon DynamoDB.
Which Amazon DynamoDB feature can you use to implement this
functionality such that there is LEAST delay in sending automatic
notifications? - CORRECT-ANSWERSAmazon DynamoDB Streams + AWS
Lambda
An Elastic Load Balancer has marked all the Amazon EC2 instances in the
target group as unhealthy. Surprisingly, when a developer enters the IP
address of the Amazon EC2 instances in the web browser, he can access the
website.
What could be the reason the instances are being marked as unhealthy?
(Select two) - CORRECT-ANSWERSThe security group of the Amazon EC2
instance does not allow for traffic from the security group of the Application
Load Balancer
The route for the health check is misconfigured
A development team has configured Elastic Load Balancing for host-based
routing. The idea is to support multiple subdomains and different top-level
domains.
The rule *.example.com matches which of the following? - CORRECT-
ANSWERStest.example.com
A startup's cloud infrastructure consists of a few Amazon EC2 instances,
Amazon RDS instances and Amazon S3 storage. A year into their business
operations, the startup is incurring costs that seem too high for their
business requirements.
Which of the following options represents a valid cost-optimization solution? -
CORRECT-ANSWERSUse AWS Cost Explorer Resource Optimization to get a
report of Amazon EC2 instances that are either idle or have low utilization
and use AWS Compute Optimizer to look at instance type recommendations
A systems administrator is creating IAM policies and attaching them to IAM
identities. After creating the necessary identity-based policies, the
administrator is now creating resource-based policies.
