Amazon AWS Certified DevOps Engineer - Professional 認定 DOP-C01 試験問題 (Q113-Q118):

質問 # 113
What flag would you use to limit a Docker container's memory usage to 128 megabytes?

A. -m 128m
B. -m 128MB
C. --memory-reservation 128m
D. -memory 128m

正解：A

解説：
Docker can enforce hard memory limits, which allow the container to use no more than a given amount of user or system memory, or soft limits, which allow the container to use as much memory as it needs unless certain conditions are met, such as when the kernel detects low memory or contention on the host machine. Some of these options have different effects when used alone or when more than one option is set. Most of these options take a positive integer, followed by a suffix of b, k, m, g, to indicate bytes, kilobytes, megabytes, or gigabytes.
Option -m or --memory
Description The maximum amount of memory the container can use. If you set this option, the minimum allowed value is 4m (4 megabyte).

質問 # 114
Your API requires the ability to stay online during AWS regional failures. Your API does not store any state, it only aggregates data from other sources - you do not have a database. What is a simple but effective way to achieve this uptime goal?

A. Create a Route53 Weighted Round Robin record, and if one region goes down, have that region redirect to the other region.
B. Use a CloudFront distribution to serve up your API. Even if the region your API is in goes down, the edge locations CloudFront uses will be fine.
C. Use an ELB and a cross-zone ELB deployment to create redundancy across datacenters. Even if a region fails, the other AZ will stay online.
D. Create a Route53 Latency Based Routing Record with Failover and point it to two identical deployments of your stateless API in two different regions. Make sure both regions use Auto Scaling Groups behind ELBs.

正解：D

解説：
Latency Based Records allow request distribution when all is well with both regions, and the Failover component enables fallbacks between regions. By adding in the ELB and ASG, your system in the surviving region can expand to meet 100% of demand instead of the original fraction, whenever failover occurs.

質問 # 115
You have an Autoscaling Group which is launching a set of t2.small instances. You now need to replace those instances with a larger instance type. How would you go about making this change in an ideal manner?

A. Createa new launch configuration with the new instance type and update yourAutoscaling Group.
B. Changethe Instance type in the current launch configuration to the new instance type.
C. Createanother Autoscaling Group and attach the new instance type.
D. Changethe Instance type of the Underlying EC2 instance directly.

正解：A

解説：
Explanation
Answer - C
The AWS Documentation mentions
A launch configuration is a template that an Auto Scaling group uses to launch EC2 instances. When you create a launch configuration, you specify information for the instances such as the ID of the Amazon Machine Image (AMI), the instance type, a key pair, one or more security groups, and a block device mapping. If you've launched an EC2 instance before, you specified the same information in order to launch the instance.
When you create an Auto Scalinggroup, you must specify a launch configuration. You can specify your launch configuration with multiple Auto Scaling groups.
However, you can only specify one launch configuration for an Auto Scalinggroup at a time, and you can't modify a launch configuration after you've created it.
Therefore, if you want to change the launch configuration for your Auto Scalinggroup, you must create a launch configuration and then update your Auto Scaling group with the new launch configuration.
For more information on launch configurations please see the below link:

質問 # 116
If designing a single playbook to run across multiple Linux distributions that have distribution specific commands, what would be the best method to allow a successful run?

A. Enable fact gathering and use the `when' conditional to match the distribution to the task.
B. Use the `shell' module to write your own checks for each command that is ran.
C. Use `ignore_errors: true' in the tasks.
D. This is not possible, a separate playbook for each target Linux distribution is required.

正解：A

解説：
Ansible provides a method to only run a task when a condition is met using the `when' declarative. With gather facts enabled, the play has access to the distribution name of the Linux system, thus, tasks can be tailored to a specific distribution and ran only when the condition is met, e.g.: ` - when: ansible_os_family == "Debian"'.

質問 # 117
You need to create a Route53 record automatically in CloudFormation when not running in production during all launches of a Template. How should you implement this?

A. Use a Parameterfor environment, and add a Condition on the Route53 Resource in the template to create the record with a null string when environment is production.
B. Use a Parameter for environment, and add a Condition on the Route53 Resource in the template to create the record only when environment is not production.
C. Create two templates, one with the Route53 record and one without it. Use the one without it when deploying to production.
D. Create two templates, one with the Route53 record value and one with a null value for the record. Use the one without it when deploying to production.

正解：B

解説：
Explanation
The optional Conditions section includes statements that define when a resource is created or when a property is defined. For example, you can compare whether a value is equal to another value. Based on the result of that condition, you can conditionally create resources. If you have multiple conditions, separate them with commas.
You might use conditions when you want to reuse a template that can create resources in different contexts, such as a test environment versus a production environment In your template, you can add an Environ me ntType input parameter, which accepts either prod or test as inputs. For the production environment, you might include Amazon CC2 instances with certain capabilities; however, for the test environment, you want to use reduced capabilities to save money. With conditions, you can define which resources are created and how they're configured for each environment type.
