Question 28 (Topic 1)

A company recently deployed MySQL on an Amazon EC2 instance with a default boot volume. The company intends to restore a 1.75 TB database. A SysOps administrator needs to provision the correct Amazon Elastic Block Store (Amazon EBS) volume. The database will require read performance of up to 10,000 IOPS and is not expected to grow in size. Which solution will provide the required performance at the LOWEST cost?

Select an option, then click Submit answer.

○ Deploy a 2 TB Cold HDD (sc1) volume.
○ Deploy a 2 TB Throughput Optimized HDD (st1) volume.
○ Deploy a 2 TB General Purpose SSD (gp3) volume. Set the IOPS to 10,000.
○ Deploy a 2 TB Provisioned IOPS SSD (io2) volume. Set the IOPS to 10,000.

Question 29 (Topic 1)

A company currently runs its infrastructure within a VPC in a single Availability Zone. The VPC is connected to the company’s on-premises data center through an AWS Site-to-Site VPN connection attached to a virtual private gateway. The on-premises route tables route all VPC networks to the VPN connection. Communication between the two environments is working correctly. A SysOps administrator created new VPC subnets within a new Availability Zone, and deployed new resources within the subnets. However, communication cannot be established between the new resources and the on-premises environment. Which steps should the SysOps administrator take to resolve the issue?

Select an option, then click Submit answer.

○ Add a route to the route tables of the new subnets that send on-premises traffic to the virtual private gateway.
○ Create a ticket with AWS Support to request adding Availability Zones to the Site-to-Site VPN route configuration.
○ Establish a new Site-to-Site VPN connection between a virtual private gateway attached to the new Availability Zone and the on-premises data center.
○ Replace the Site-to-Site VPN connection with an AWS Direct Connect connection.

Reference / correct answer:

Add a route to the route tables of the new subnets that send on-premises traffic to the virtual private gateway.

Most accepted answer: A. Add a route to the route tables of the new subnets that send on-premises traffic to the virtual private gateway.

Community votes: A=2

Selected Answer: A Site-to-Site VPN connects the customer's GW with the VGW in the VPC. Therefore, since the VGWs in the VPC are connected, you only need to add routing tables. upvoted 3 times

Selected Answer: A When new subnets are created within a new Availability Zone, they are associated with their own route tables. By default, these route tables do not have the necessary route to direct traffic from the new subnets to the on-premises data center via the existing Site-to-Site VPN connection. The SysOps administrator needs to add a route in the route table of the new subnets that points to the virtual private gateway, just like the route that is already present in the route table of the existing subnet. upvoted 2 times

A is correct In the current setup, the on-premises route tables already route all VPC networks to the VPN connection, which is attached to the virtual private gateway. However, when new subnets are created in a new Availability Zone, they have their own route tables. By default, these new route tables do not include the necessary route to direct traffic to the on-premises data center through the VPN connection. upvoted 2 times

Question 30 (Topic 1)

A SysOps administrator needs to provision a new fleet of Amazon EC2 Spot Instances in an Amazon EC2 Auto Scaling group. The Auto Scaling group will use a wide range of instance types. The configured fleet must come from pools that have the most availability for the number of instances that are launched. Which solution will meet these requirements?

Select an option, then click Submit answer.

○ Launch the Spot Instances up to the maximum capacity of the Auto Scaling group.
○ Launch the Spot Instances by using the diversified strategy.
○ Launch the Spot Instances by using the capacity optimized strategy.
○ Use the Spot Instance advisor to help determine the best Spot allocation strategy.

Reference / correct answer:

Launch the Spot Instances by using the capacity optimized strategy.

Most accepted answer: C. Launch the Spot Instances by using the capacity optimized strategy.

Community votes: C=4, D=2

Selected Answer: C capacity-optimized strategy automatically analyzes the available Spot capacity pools and selects the pool that provides the highest chance of launching the desired number of instances. Spot Instance Advisor can provide guidance on Spot instance pricing and interruption history, but it does not specifically address the goal of selecting pools with the most availabilit https://aws.amazon.com/about-aws/whats-new/2019/08/new-capacity-optimized-allocation-strategy-for-provisioning-amazon-ec2-spot-instances/ upvoted 7 times

Selected Answer: C https://aws.amazon.com/blogs/compute/introducing-price-capacity-optimized-allocation-strategy-for-ec2-spot-instances/ upvoted 4 times

Selected Answer: C https://docs.aws.amazon.com/whitepapers/latest/cost-optimization-leveraging-ec2-spot-instances/spot-best-practices.html Use the price and capacity optimized allocation strategy. Allocation strategies in EC2 Auto Scaling groups help you to provision your target capacity without the need to manually look for the Spot Instance pools with spare capacity. We recommend using the price-capacity-optimized strategy because this strategy automatically provisions instances from the most-available Spot Instance pools that also have the lowest possible price. Because your Spot Instance capacity is sourced from pools with optimal capacity, this decreases the possibility that your Spot Instances are interrupted. For more information about allocation strategies, see Spot Instances in the Amazon EC2 Auto Scaling User Guide. upvoted 3 times

Selected Answer: D Tip: Deploying your application across many instance types will further enhance availability. Consider using EC2 Autoscaling, which makes diversification across multiple instance types and availability zones easier. We recommend starting with instance types having lower frequency of being interrupted and adding more instance types as you improve your application’s flexibility and fault tolerance. See the Best Practices section for more tips and tricks. The average frequency of interruption across all Regions and instance types is <5%.
