CloudWatch from Amazon EC2? (Choose 3)

A user can define a custom metric with AWS CloudWatch?

What best describes burstable performance for t2 micro instances?

One of your instances is not responding. After investigating you see that the system
status checks indicate a problem. What would be the best method for attempting to fix a
failing system status check?

You currently have Apache webservers on EC2 instances which receive requests from
your ELB. Those webservers return results from your PHP application. This application
connects to an RDS database instance to read and write data. A few months ago, you
realized that ElastiCache with Redis could reduce the load on your RDS database by
caching some of the popular data. Fast-forward to today, and your ElastiCache Redis cluster
is under a heavy read load and needs to scale. Which of these is the best way to scale your
cluster?

You’ve been tasked with optimizing costs in your company’s AWS environment. After
logging in, you discover that there are 3 unused elastic IP addresses, 6 RDS instances that
have not had a DB connection for over 7 days, 5 instances that are running at an average
CPU utilization of < 5% and one EC2 instance running at 80% utilization. Your company
has not purchased any reserved instances but is highly concerned over AWS costs. As a
SysOps administrator you know that you can easily help reduce costs and make the
company happy again, select all of the statements below that you might do in order to
optimize costs quickly.

In order to monitor operating system-level metrics such as disk usage, swap usage, and
memory usage, you must install EC2 monitoring scripts. These scripts put custom metric
data into Amazon CloudWatch. What do you need to do in order to give the instance
permissions to put those custom metrics in CloudWatch?

Your system status check has failed? What should you do to troubleshoot the issue?

when you define an alarm in Cloudwatch What are the possible actions available?
(Choose 3)

You are planning to deploy a production database to EC2 and need to choose the best
storage type. You anticipate that you will need 20,000 IOPS, and an average of 8,000 –
10,000 IOPS. What storage medium should you choose?

ElastiCache is being used to cache your web application. Memcached is being used as
the caching engine. The caching seems to be getting slower. You have to diagnose the cause
of this issue. What parameter should be adjusted if you find that the overhead pool is 50
mb?

To monitor the lag between the primary RDS instance and the read replica, which of
the following metric is used?

An organization has configured Auto Scaling with ELB. One of the instance health
check returns the status as Impaired to Auto Scaling. What will Auto Scaling do in this
scenario?

when it comes to pre-warming (also called initialization for EC2) What is the best
practice?

To send traffic to a secondary host in the event that the primary host went down,
what would we need to attach to a Bastion host or NAT host for high availability? Chose
the correct answer

In five regions around the globe your website is hosted in 10 EC2 instances. How
could you configure your site to maintain availability with minimum downtime if one of
the five regions was to lose network connectivity for an extended period?

Due to some manual error, one of the instances got rebooted in an organization’s
system that has setup Auto Scaling with ELB. Thus, it failed the Auto Scaling health
check. Auto Scaling has marked it for replacement. How can the system admin ensure
that the instance does not get terminated?

If you want to add more availability zones to existing ELB and you want to perform
this activity from CLI. Which of the below mentioned command helps the system admin
to add new zones to the existing ELB?

How do you force a failover from an RDS instance one AZ to an instance in another
AZ?

Read replicas can have multiple AZs for redundancy

You can have read replicas of read replicas?

when it comes to pre-warming (also called initialization for EC2) What is the best
practice?

You have configured ELB with Auto Scaling. You have suspended the Auto Scaling
AddToLoadBalancer (which adds instances to the load balancer). process for a while.
What will happen to the instances launched during the suspension period?

An organization need to run a business intelligence application against their
production database. This application requires real time data from the database. How
should they configure their RDS setup so that the application does not increase I/O load
against the production database?

If you want to optimize performance for a compute cluster that requires low internode latency, which feature in the following list should you use?

How can the user achieve detailed monitoring? if A user has created a launch
configuration for Auto Scaling where CloudWatch detailed monitoring is disabled

How can the user achieve to prohibit any mistakes from the production team to
avoid accidental termination? if A user has launched an EC2 instance and deployed a
production application in it

To restrict access to data in S3 Which features can be used? Choose the 3 correct
answers from the options below.

With the following components; You run a stateless web application an Elastic Load
Balancer, three Web/Application servers on EC2, and a MySQL RDS database with 5000
Provisioned Average response time for users is increasing. Looking at CloudWatch, you observe 95% CPU usage on the Web/Application servers and 20% CPU usage on the
database. The average number of database disk operations varies between 2000 and 2500.
How would you improve performance?
