Adaface Azure DevOps测试 is the most accurate way to shortlist Azure Devops工程师s



Reason #1

Tests for on-the-job skills

The Azure DevOps测试 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:

  • 能够使用正确的语法和凹痕编写Python代码
  • 精通Python脚本以实现自动化目的
  • 能够使用命令行界面导航和操纵Linux文件系统
  • 精通编写外壳脚本来自动化Linux中的任务

  • 了解Azure中的网络概念
  • 熟悉Azure数据库及其功能
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.

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 Azure DevOps测试(Azure,Linux,Python) 将是不可行的.

Backup and Restore Strategy
Databases
Backup
Recovery
Try practice test
You are a database administrator for an organization that uses Azure SQL Database for its operations. The organization has a strict data retention policy and has set up the following backup strategy:

1. Full backups are taken every Sunday at midnight.
2. Differential backups are taken every day at midnight, excluding Sunday.
3. Transaction log backups are taken every hour on the hour.

On Wednesday at 2:30 PM, a failure occurred, and the latest backup files available are: full backup from the previous Sunday, differential backups for Monday and Tuesday, and transaction log backups up to Wednesday 2 PM.

In order to restore the database to the most recent point in time with the minimum amount of data loss, in what order should you restore the backups?
A: Restore the full backup, then the differential backup for Tuesday, then the differential backup for Wednesday, then each transaction log backup from midnight on Wednesday to 2 PM on Wednesday.

B: Restore the full backup, then the differential backup for Wednesday, then each transaction log backup from midnight on Wednesday to 2 PM on Wednesday.

C: Restore the full backup, then each differential backup from Monday and Tuesday, then each transaction log backup from midnight on Wednesday to 2 PM on Wednesday.

D: Restore the full backup, then the differential backup for Monday, then each transaction log backup from midnight on Monday to 2 PM on Wednesday.

E: Restore the full backup, then the differential backup for Tuesday, then each transaction log backup from midnight on Tuesday to 2 PM on Wednesday.

Resolving Connection Issues
Virtual Machines

Security
Try practice test
You are an Azure Administrator and you manage a Linux VM running an internal web application in Azure. The web application communicates with a database server hosted on another VM in the same Virtual Network (VNet).

Recently, users have reported that the web application is not accessible. After initial troubleshooting, you have identified that the web application VM is unable to establish a connection with the database server VM on port 5432.

You have checked and confirmed the following:

1. Both VMs are up and running without any issues.
2. Both VMs are located in the same VNet and subnet.
3. Both VMs can successfully ping each other.
4. A Network Security Group (NSG) is associated with the subnet, and it has a rule allowing all outbound traffic from the web application VM.
5. The NSG rule for inbound traffic to the database VM on port 5432 has a higher priority than the default deny all rule.

Given the information provided, what could be the most likely reason for the issue and the appropriate resolution?
A: Add a route table to the subnet to enable communication between the VMs.

B: The NSG rule priority for the inbound traffic to the database VM is not set correctly. Adjust the priority to be lower than the default rule.

C: Check if a firewall is enabled on the database VM that might be blocking the port. If so, configure it to allow connections on port 5432.

D: The issue is related to the DNS resolution. Update the DNS settings in the VNet to enable name resolution between the VMs.

E: The web application is not correctly configured to connect to the database. Update the connection string in the web application configuration.

Resolving NSG Configuration Issues
Virtual Machines
Security
Try practice test
You are an Azure Administrator in a software development company. A Linux VM is deployed on Azure, hosting an application server running on port 5000, set to start whenever the VM is booted up.

The VM is associated with a Network Security Group (NSG) having the following inbound security rules:

- Rule 100 (Priority: 100): Allow SSH (port 22) from any source
- Rule 200 (Priority: 200): Allow HTTP (port 80) from any source
- Rule 400 (Priority: 400): Allow TCP traffic on port 5000 from any source
- Rule 300 (Priority: 300): Deny all inbound traffic from any source

The outbound security rules are configured to allow all traffic to any destination.

Internal users have been attempting to connect to the application server on port 5000 but they are consistently facing connection timeouts. You've confirmed the application server is up and running, and you can connect to the server locally on the VM.

What is the most probable cause of the problem and how would you fix it?
A: The inbound rule to allow TCP traffic on port 5000 is conflicting with the rule to allow HTTP on port 80. Remove Rule 200.

B: Rule 300 to deny all inbound traffic is being processed before Rule 400 to allow traffic on port 5000. Modify the priority of Rule 400 to a value less than 300.

C: The application server should be configured to listen on a well-known port instead of port 5000. Change the server settings.

D: The NSG is missing an inbound rule to allow ICMP traffic. Add a new rule with a lower priority.

E: The NSG needs to have an outbound rule specifically allowing traffic to port 5000. Add a new outbound rule.

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 }

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?

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Azure DevOps测试(Azure,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.
