AMAZON CLOUD PRACTITIONER CERTIFICATION EXAM
QUESTIONS WITH VERIFIED SOLUTIONS
What are the three fundamental characteristics you pay for in AWS? -- Answer ✔✔
Compute, storage, and data transfer out.
Which Amazon Services are offered at no-charge? -- Answer ✔✔ Amazon VPC
Amazon Beanstalk
Amazon CloudFormation
Amazon IAM
Amazon Auto-Scaling
Amazon OpsWorks
What is Reduced Redundancy Storage? -- Answer ✔✔ Reduced Redundancy Storage
(RRS) is an Amazon S3 storage option that enables customers to reduce their costs by
storing noncritical, reproducible data at lower levels of redundancy than Amazon S3's
standard storage.
What is a Spot Instance? -- Answer ✔✔ Spot instances are spare EC2 capacity that can
save you up 90% off of On-Demand prices that AWS can interrupt with a 2-minute
notification. Spot uses the same underlying EC2 instances as On-Demand and Reserved
Instances, and is best suited for fault-tolerant, flexible workloads
Which type of AWS storage is analogous to virtual disks in the cloud? -- Answer ✔✔
Elastic Block Storage (EBS)
True/False: EBS volumes persist beyond the life of an EC2 instance. -- Answer ✔✔ True
Elastic Block Storage (EBS) -- Answer ✔✔ Block level storage volumes for use with EC2
instances
, True/False: Each Amazon EBS volume is automatically replicated within its Availability
Zone to protect you from component failure. -- Answer ✔✔ True
What are the Benefits of AWS EBS? -- Answer ✔✔ - Reliable and Secure Storage
- Consistent Low Latency Performance
- Long-term durability of data - point in time snapshots
-Scale up/down quickly
-Geographic Flexibility
- Optimized Performance
What EBS storage is available in the free-tier for the 1st year? -- Answer ✔✔ 30 GB of
Amazon Elastic Block Storage in any combination of General Purpose (SSD) or
Magnetic, plus 2 million I/Os (with EBS Magnetic) and 1 GB of snapshot storage*
What is the Amazon RDS? -- Answer ✔✔ RDS - Relational Database Service is a web
service that makes it easy to setup, operate, and scale a relational database in the cloud.
It takes away the time consuming tasks of hardware-provisioning, setup, patching, and
backups so you can focus on your applications.
Which database engines are available in the AWS RDS? -- Answer ✔✔ Amazon Aurora,
PostgreSQL, MySQL, MariaDB, Oracle, and Microsoft SQL Server are available in the
AWS RDS.
What does Amazon manage on my behalf for RDS? -- Answer ✔✔ *Provisioning
Infrastructure Capacity, Installing Software, replication of db across multiple AZ's (mult-
AZ deployment), backups, patching software, and failovers are managed on behalf of
RDS users.
What is the difference between using RDS and running an EC2 instance with a RDB
installed? -- Answer ✔✔ The difference in these deployments is that you manage your
own database in the cloud.
How is the use of AWS RDS billed? -- Answer ✔✔ * Database instance hours
* Storage (amount of data stored in GB)
* Number of Input/output Requests
* Provisioned IOPS rate regardless of what is consumed.
