Adaface AWS DevOps Assessment Test is the most accurate way to shortlist AWS Devops工程师s



Reason #1

Tests for on-the-job skills

The AWS DevOps Test helps recruiters and hiring managers identify qualified candidates from a pool of resumes, and helps in taking objective hiring decisions. It reduces the administrative overhead of interviewing too many candidates and saves time by filtering out unqualified candidates at the first step of the hiring process.

The test screens for the following skills that hiring managers look for in candidates:

  • 能够使用Python进行脚本和自动化
  • 熟练使用Linux命令行界面
  • 了解AWS核心服务及其功能
  • 有能力配置和管理AWS资源
  • 擅长进行故障排除和调试AWS问题
  • 知识渊博的基础知识
  • 精通Python中的面向对象的编程(OOPS)概念
  • 能够与Python中的不同数据结构一起工作
  • 熟悉Linux基础知识
  • 精通外壳脚本
Reason #2

No trick questions

no trick questions

Traditional assessment tools use trick questions and puzzles for the screening, which creates a lot of frustration among candidates about having to go through irrelevant screening assessments.

View sample questions

The main reason we started Adaface is that traditional pre-employment assessment platforms are not a fair way for companies to evaluate candidates. At Adaface, our mission is to help companies find great candidates by assessing on-the-job skills required for a role.

Why we started Adaface
Reason #3

Non-googleable questions

We have a very high focus on the quality of questions that test for on-the-job skills. Every question is non-googleable and we have a very high bar for the level of subject matter experts we onboard to create these questions. We have crawlers to check if any of the questions are leaked online. If/ when a question gets leaked, we get an alert. We change the question for you & let you know.

How we design questions

这些只是我们库中有10,000多个问题的一个小样本。关于此的实际问题 AWS DevOps测试(AWS,Linux,Python) 将是不可行的.

Session
File Handling
Dictionary
Solve
 image
The function high_sess should compute the highest number of events per session of each user in the database by reading a comma-separated value input file of session data. The result should be returned from the function as a dictionary. The first column of each line in the input file is expected to contain the user’s name represented as a string. The second column is expected to contain an integer representing the events in a session. Here is an example input file:
Tony,10
Stark,12
Black,25
Your program should ignore a non-conforming line like this one.
Stark,3
Widow,6
Widow,14
The resulting return value for this file should be the following dictionary: { 'Stark':12, 'Black':25, 'Tony':10, 'Widow':14 }

Solve
Consider the following Python code:
 image
In the above code, recursive_search is a function that takes a dictionary (data) and a target key (target) as arguments. It searches for the target key within the dictionary, which could potentially have nested dictionaries and lists as values, and returns the value associated with the target key. If the target key is not found, it returns None.

nested_dict is a dictionary that contains multiple levels of nested dictionaries and lists. The recursive_search function is then called with nested_dict as the data and 'target_key' as the target.

What will the output be after executing the above code?

Solve
ChickTok is a dating app that runs on EC2 behind an ALB. The EC2 instances run in an EC2 Auto Scaling group across multiple AZ. On every Saturday night, the app becomes atleast 5 times slower. Upon investigation, it is found that the CPU utilization reaches 100% within a matter of seconds instead of being a gradual increment. This is happening due to a batch core dating algorithm update that happens on every Saturday 9PM. 
ChickTok wants a solution that

- Tackles the extra workload
- Avoids downtime

EC2DataProcessing
EC2
S3
Security Groups
Network ACLs
Solve
You work as a Solutions Architect for a data analysis firm. The company stores large datasets on Amazon S3, and you've been tasked with setting up an Amazon EC2 instance to process this data. The EC2 instance will fetch data from S3, process it, and then write the results back to a different S3 bucket.

To ensure security, the EC2 instance should not have direct internet access, and it should only be able to communicate with the S3 buckets. You've decided to place the EC2 instance in a VPC private subnet with a CIDR block of 10.0.1.0/24. The associated security group is set to deny all inbound traffic and allow all outbound traffic.

Which additional configuration should you make to enable the EC2 instance to access the S3 buckets while complying with the security requirements?
A: Modify the Network ACL of the subnet to allow outbound connections to the IP range of the S3 service.
B: Assign a Public IP to the EC2 instance and update the security group to allow inbound and outbound traffic to S3.
C: Add a NAT Gateway in the private subnet and update the route tables to direct S3 traffic to the NAT Gateway.
D: Create an S3 VPC Gateway Endpoint and update the route tables for the private subnet to direct S3 traffic to the VPC Endpoint.
E: Create a VPN connection from the VPC to the S3 buckets.

Orderly Restoration of RDS with Transaction Logs
RDS
Transaction Logs
Point-in-time recovery
Solve
You work as a database manager for a fintech company that uses an AWS RDS PostgreSQL instance. The company abides by stringent data security standards, which require minimal data loss in the event of database failures or accidental data modifications.

Unexpectedly, an operation that updates a significant number of records in a crucial transaction table is mistakenly run. You discover that this operation occurred at 12:45 PM. Your RDS PostgreSQL instance is configured to perform automated backups every day at 1:00 AM, with transaction logs being backed up every 5 minutes. Furthermore, there is a manual DB snapshot taken at 11:00 AM on the same day. 

To restore the database with minimal data loss, considering the sequence and order of log application, which of the following steps should you execute?
A: Restore from the manual DB snapshot at 11:00 AM, then perform a point-in-time recovery to 12:45 PM.
B: Perform a point-in-time recovery to 12:45 PM.
C: Restore from the last automated backup at 1:00 AM, then apply all transaction logs until 12:45 PM.
D: Restore from the manual DB snapshot at 11:00 AM, then apply transaction logs from 11:00 AM to 12:45 PM.
E: Perform a point-in-time recovery to 11:00 AM, then apply transaction logs from 11:00 AM to 12:45 PM.

SecureEC2Setup
EC2
Security Groups
VPC
Solve
As an AWS Cloud Engineer for a financial institution, you're setting up an EC2 instance in a VPC to host a web application that handles sensitive financial data. The EC2 instance is placed in a private subnet and associated with a security group that only allows inbound HTTPS (port 443) traffic from the internet. You have an Application Load Balancer (ALB) in a public subnet, which forwards incoming traffic to the EC2 instance.

However, during the testing phase, you find that the web application on the EC2 instance is not reachable from the internet, but works fine from within the VPC. 

What could be the reason for this?
A: The security group should allow inbound traffic from the ALB's security group, not the internet.
B: The ALB should be in the private subnet, not the public subnet.
C: EC2 instances hosting sensitive data cannot be reached through an ALB.
D: The ALB and EC2 instance must be in the same subnet.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment AWS DevOps测试(AWS,Linux,Python) in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests
Reason #6

1 click candidate invites

Email invites: You can send candidates an email invite to the AWS DevOps测试(AWS,Linux,Python) from your dashboard by entering their email address.
