Question : You have a Linux EC web server instance running inside a VPC The instance is In a public
subnet and has an EIP associated with it so you can connect to It over the Internet via HTTP or
SSH The instance was also fully accessible when you last logged in via SSH. and was also
serving web requests on port 80.
Now you are not able to SSH into the host nor does it respond to web requests on port 80 that
were working fine last time you checked You have double-checked that all networking
configuration parameters (security groups route tables. IGW'EIP. NACLs etc) are properly
configured {and you haven't made any changes to those anyway since you were last able to reach
the Instance). You look at the EC2 console and notice that system status check shows "impaired."
Which should be your next step in troubleshooting and attempting to get the instance back to a
healthy state so that you can log in again?


: You have a Linux EC web server instance running inside a VPC The instance is In a public
1. Stop and start the instance so that it will be able to be redeployed on a healthy host system that
most likely will fix the "impaired" system status
2. Reboot your instance so that the operating system will have a chance to boot in a clean healthy
state that most likely will fix the 'impaired" system status
 3. Access Mostly Uused Products by 50000+ Subscribers
since the networking stack of the OS may be locked up causing the "impaired" system status.
4. Add another Elastic Network Interface to the instance and try to connect via that new path since
the networking stack of the OS may be locked up causing the "impaired" system status
5. un-map and then re-map the EIP to the instance, since the IGW/NAT gateway may not be
working properly, causing the "impaired" system status

Explanation: Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud.
It provides cost-efficient and resizable capacity, while managing time-consuming database administration tasks, freeing you up to focus on your applications
and business.

Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle, SQL Server, or PostgreSQL database. This means that the code, applications, and
tools you already use today with your existing databases should work seamlessly with Amazon RDS. Amazon RDS automatically patches the database software and
backs up your database, storing the backups for a user-defined retention period. You benefit from the flexibility of being able to scale the compute
resources or storage capacity associated with your relational database instance via a single API call or few clicks of the AWS Management Console . In
addition, Amazon RDS makes it easy to use replication (currently supported for MySQL and Oracle database engines) to enhance database availability, improve
data durability, or scale beyond the capacity constraints of a single database instance for read-heavy database workloads. As with all Amazon Web Services,
there are no up-front investments required, and you pay only for the resources you use.





Question :

What is an Amazon RDS master user account and how is it different from an AWS account?
:
1. A master user account is different from an AWS developer account and used only within the context of Amazon RDS to control access to your DB
Instance(s).
2. The master user account is a native database user account which you can use to connect to your DB Instance.
3. Access Mostly Uused Products by 50000+ Subscribers
4. Only 1 and 3 are correct
5. Only 1 and 2 are correct

Correct Answer : Get Lastest Questions and Answer :

To begin using Amazon RDS you will need an AWS developer account. If you do not have one prior to signing up for Amazon RDS,
you will be prompted to create one when you begin the sign-up process. A master user account is different from an AWS developer account
and used only within the context of Amazon RDS to control access to your DB Instance(s). The master user account is a native database
user account which you can use to connect to your DB Instance. You can specify the master user name and password you want associated
with each DB Instance when you create the DB Instance. Once you have created your DB Instance, you can connect to the database using
the master user credentials. Subsequently, you may also want to create additional user accounts so that you can restrict who can access your DB Instance.
