UPDATED ACTUAL Questions and
CORRECT Answers
When you launch an Amazon Elastic Compute Cloud (Amazon EC2) instance, what does the
instance type define? - CORRECT ANSWER✔✔- The amount of compute for an Amazon
EC2 instance, including RAM, instance storage, CPU, and network bandwidth.
When you launch an Amazon Elastic Compute Cloud (Amazon EC2) instance, what is
defined by the Amazon Machine Image (AMI)? - CORRECT ANSWER✔✔- The initial
software state of the instance when launched, including operating system, configuration, and
additional installed programs.
What is the drawback of Spot Instances? - CORRECT ANSWER✔✔- They can be
terminated when the spot price goes above your current bid price.
How does the Amazon Elastic Compute Cloud (Amazon EC2) ReservedInstance pricing
model work? span> - CORRECT ANSWER✔✔- You pay up front to reserve compute for
one or three years, locking in a lower cost in the process.
What is the Amazon Elastic Compute Cloud (Amazon EC2) On Demand pricing model? -
CORRECT ANSWER✔✔- You launch Amazon EC2 instances on request and pay the full
hourly cost until you stop or terminate the instances. This is the most flexible and least cost-
effective pricing model.
How can you address an Amazon Elastic Compute Cloud (Amazon EC2) instance to connect
over the Internet? - CORRECT ANSWER✔✔- By public IP address, elastic IP address,
orDNS name. net?
What is Enhanced Networking for Amazon Elastic Compute Cloud (Amazon EC2)? -
CORRECT ANSWER✔✔- A setting to get higher packet per second, lower network jitter,
and lower latencies.
, What type of block storage is provided at no additional charge with certain Amazon Elastic
Compute Cloud (Amazon EC2) instance types? - CORRECT ANSWER✔✔- Instance Store
(or ephemeral storage).
VM Import/Export allows you to import existing virtual machines from your local
environment and convert them to what? - CORRECT ANSWER✔✔- Amazon Elastic
Compute Cloud (Amazon EC2) instances or Amazon Machine Images (AMIs).
Which storage option continues to store data despite stopping and starting an instance? -
CORRECT ANSWER✔✔- Amazon Elastic Block Store (Amazon EBS).
What are the four network capacity ratings for Amazon Elastic Compute Cloud (Amazon
EC2) instance types? - CORRECT ANSWER✔✔- Low, moderate, high, and 10 Gbps.
What is instance metadata? - CORRECT ANSWER✔✔- Data about an Amazon Elastic
Compute Cloud (Amazon EC2) instance—such as instance ID, instance type, and security
groups—that can be obtained via an HTTP call from within the instance.
What are the four properties of a security group rule? - CORRECT ANSWER✔✔- Traffic
direction, port, protocol, and destination (or source) address.
When an Amazon Elastic Compute Cloud (Amazon EC2) instance is a member of two
security groups, what resulting traffic flow is allowed? - CORRECT ANSWER✔✔- The
rules from each security group are aggregated to create one set of permissive rules, so the
result is a union of all traffic allowed by the rules in both security groups.
Which Amazon Elastic Block Storage (Amazon EBS) volume type is the best choice for
workloads such as large databases executing many transactions? - CORRECT ANSWER✔✔-
Provisioned IOPS SSD.
What Amazon Elastic Block Storage (Amazon EBS) volume type is appropriate for cold and
infrequently accessed data? - CORRECT ANSWER✔✔- Magnetic volumes.
