1. A. 224 GB
2. B. 124 GB
3. C. 184 GB
4. D. 244 GB

Correct Answer: D
The CR1 instances are part of the memory optimized instances. They offer lowest cost per GB RAM among all the AWS instance families. CR1 instances are part of the new generation of memory optimized instances, which can offer up to 244 GB RAM and run on faster CPUs (Intel Xeon E5-2670 with NUMA support) in comparison to the NI2 instances of the same family. They support cluster networking for bandwidth intensive applications. cr1.8x|arge is one of the largest instance types of the CR1 family, which can offer 244 GB RAM.

You are responsible for a web application that consists of an Elastic Load Balancing (ELB) load balancer in front of an Auto Scaling group of Amazon Elastic Compute Cloud (EC2) instances. For a recent deployment of a new version of the application, a new Amazon Machine Image (AMI) was created, and the Auto Scaling group was updated with a new launch configuration that refers to this new AMI. During the deployment, you received complaints from users that the website was responding with errors. All instances passed the ELB health checks.
What should you do in order to avoid errors for future deployments? (Choose 2 answer)

1. A. Add an Elastic Load Balancing health check to the Auto Scaling grou
2. B. Set a short period for the health checks to operate as soon as possible in order to prevent premature registration of the instance to theload balancer.
3. C. Enable EC2 instance C|oudWatch alerts to change the launch configuration’s AMI to the previous on
4. D. Gradually terminate instances that are using the new AMI.
5. E. Set the Elastic Load Balancing health check configuration to target a part of the application that fully tests application health and returns an error if the tests fail.
6. F. Create a new launch configuration that refers to the new AMI, and associate it with the grou
7. G. Double the size of the group, wait for the new instances to become healthy, and reduce back to the original size.If new instances do not become healthy, associate the previous launch configuration.
8. H. Increase the Elastic Load Balancing Unhealthy Threshold to a higher value to prevent an unhealthy instance from going into service behind the load balancer.

Correct Answer: CD

Which of the following statements is correct about AWS Direct Connect?

1. A. Connections to AWS Direct Connect require double clad fiber for 1 gigabit Ethernet with Auto Negotiation enabled for the port.
2. B. An AWS Direct Connect location provides access to Amazon Web Services in the region it is associated with.
3. C. AWS Direct Connect links your internal network to an AWS Direct Connect location over a standard 50 gigabit Ethernet cable.
4. D. To use AWS Direct Connect, your network must be colocated with a new AWS Direct Connect locatio

Correct Answer: B
AWS Direct Connect links your internal network to an AWS Direct Connect location over a standard 1 gigabit or 10 gigabit Ethernet fiber-optic cable. An AWS Direct Connect location provides access to Amazon Web Services in the region it is associated with, as well as access to other US regions. To use AWS Direct Connect, your network is colocated with an existing AWS Direct Connect location. Connections to AWS Direct Connect require single mode fiber, 1000BASE-LX (1310nm) for 1 gigabit Ethernet, or 10GBASE-LR (1310nm) for 10 gigabit Ethernet. Auto Negotiation for the port must be disabled.

A user is trying to create a PIOPS EBS volume with 3 GB size and 90 IOPS. Will AWS create the volume?

1. A. No, since the PIOPS and EBS size ratio is less than 30
2. B. Yes, since the ratio between EBS and IOPS is less than 30
3. C. No, the EBS size is less than 4GB
4. D. Yes, since PIOPS is higher than 100

Correct Answer: C
A Provisioned IOPS (SSD) volume can range in size from 4 GiB to 16 TiB and you can provision up to 20,000 IOPS per volume.
