EXAMINATION TEST COMPLETE
QUESTIONS AND SOLUTIONS
◉ Encrypting data in transit
Answer: -TLS and SSL
-process guarantees that data is encrypted before leaving the
client's environment and decrypted upon arrival
-minimizes risk of interception and tampering
◉ Encrypting data at rest
Answer: -data is encrypted on server to keep it secure
-uses special key managed by user
◉ Client side encryption
Answer: - in this process, users retain control over the encryption
keys responsible for encrypting and decrypting data before
transmission
◉ AWS Inspector
Answer: -examines unintended network accessibility and assess
operating systems known for vulnerabilities
-Integrate AWS Inspector with AWS Security Hub and send
findings to EventBridge.
,-leverage AWS Inspector's findings to prioritize and address
security issues for enhanced protection.
◉ Amazon EFS (Elastic File Storage)
Answer: -designed for shared file access and scaling to petabyte
data store
-Amazon EFS provides simple, scalable, elastic file storage for use
with compute instances on the AWS Cloud and on-premises
servers. Amazon EFS is easy to use offering a simple interface that
allows you to create and configure file systems quickly and easily.
◉ Simple routing policy
Answer: Use for a single resource that performs a given function
for your domain, for example, a web server that serves content for
the example.com website. You can use simple routing to create
records in a private hosted zone.
◉ Failover routing policy
Answer: Use when you want to configure active-passive failover.
You can use failover routing to create records in a private hosted
zone.
◉ Geolocation routing policy
Answer: Use when you want to route traffic based on the location
of your users. You can use geolocation routing to create records in
a private hosted zone.
,◉ Geoproximity routing policy
Answer: Use when you want to route traffic based on the location
of your resources and, optionally, shift traffic from resources in
one location to resources in another location. You can use
geoproximity routing to create records in a private hosted zone.
◉ Latency routing policy
Answer: Use when you have resources in multiple AWS Regions
and you want to route traffic to the Region that provides the best
latency. You can use latency routing to create records in a private
hosted zone.
◉ IP-based routing policy
Answer: Use when you want to route traffic based on the location
of your users, and have the IP addresses that the traffic originates
from.
◉ Multivalue answer routing policy
Answer: se when you want Route 53 to respond to DNS queries
with up to eight healthy records selected at random. You can use
multivalue answer routing to create records in a private hosted
zone.
◉ Weighted routing policy
Answer: Use to route traffic to multiple resources in proportions
that you specify. You can use weighted routing to create records in
a private hosted zone.
, ◉ AWS Trusted Advisor
Answer: -provides recommendations that help you follow best
practices
-uses checks to evaluate account and i.d ways to improve
infrastructure, security, performance, reduce costs, and monitor
service quotas
◉ AWS Snowball
Answer: -data transport solution and data migration
◉ AWS IoT Core
Answer: -managed cloud service that connects Internet of Things
(IoT) devices to the broader AWS ecosystem
-it supports device communication, data management, analytics,
and application development, providing a full-stack solution for
building and scaling IoT systems
Features:
-device gateway
-message broker
-rules engine
-device registry
-authentication and authorization
-device shadow
-AWS IoT Device SDK
