1. Which Amazon offering provides the ability to deploy a
managed MySQL instance?
Amazon Neptune
Amazon Dynamo DB
Amazon ElastiCache
Amazon RDS - ANSWER ✓ Amazon Relational
Database Service (RDS) provides the ability to deploy a
managed MySQL instance, along with a number of
other relational database products, including Microsoft
SQL Server, Oracle, PostgreSQL, Amazon Aurora, and
MariaDB.
,2. Configure the ELB to implement Auto Scaling based on
health checks - ANSWER ✓ Auto Scaling adjusts the
number of EC2 instances based on demand. Health
checks trigger the launch of new instances if failures
occur, ensuring high availability.
3. Configure the ELB for cross-zone load balancing -
ANSWER ✓ Enables an ELB to evenly distribute
traffic across all instances in all Availability Zones,
improving load distribution but not directly addressing
instance failures.
4. Scheduled scaling - ANSWER ✓ An option that
automatically adjusts the number of EC2 instances
based on predefined schedules, suitable for applications
with regular seasonal demand changes.
5. Regular Seasonal Increases in Demand - ANSWER ✓
Demand patterns that are predictable and occur at
specific times, such as certain months of the year or
specific days of the week.
, 6. No Modifications to the Application - ANSWER ✓
Requiring a solution that works with the existing
application without any changes to the application code
or architecture.
7. Automatic Adaptation - ANSWER ✓ The scaling
strategy automatically adjusts resources to handle
increases in demand.
8. Predictive Scaling - ANSWER ✓ Uses machine
learning to forecast demand and adjust the number of
EC2 instances in anticipation of traffic changes.
9. Dynamic Scaling - ANSWER ✓ Adjusts the number of
EC2 instances in real-time based on current demand
metrics like CPU utilization, memory usage, or request
rates.
10. Scheduled Scaling - ANSWER ✓ Allows increasing
or decreasing the number of EC2 instances at specific
times based on a predefined schedule, suitable for
predictable workloads.
