Question
A cloud administrator is implementing a configuration management solution to ensure all nodes on the network meet requirements. However, when the administrator tests the solution, the control node is unable to reach the managed nodes. What are some possible reasons why? (Select all that apply.)
A.The control node obtained an IP address from the DHCP (Dynamic Host Configuration Protocol) server.
B.The administrator has not allowed traffic from the control node through the firewalls.
C.The DNS servers have a resource record for the control node name and IP address.
D.The administrator moved the managed nodes to a different environment.
A.The control node obtained an IP address from the DHCP (Dynamic Host Configuration Protocol) server.
B.The administrator has not allowed traffic from the control node through the firewalls.
D.The administrator moved the managed nodes to a different environment.
If the control node obtained an IP address from the DHCP server, the address of the control node would not remain constant and would cause it to be unable to reach the managed nodes.
If the administrator has not allowed traffic from the control node through the firewalls, then the firewalls would block the control node from reaching the managed nodes.
If the administrator moved the managed nodes to a different environment, the managed nodes would not be available for the control node to connect to.
A server administrator is attempting to look for pre-configured automated tasks that are already built. They find a system that uses Ruby scripts, support common operating systems and can be used with physical machines, VM’s, and cloud instances. Which of the following tools will the administrator need to use?
A.Bash
B.Puppet
C.PowerShell
D.Ansible
B.Puppet
Puppet files are written with Ruby. Puppet supports all of the common operating systems and may be used with physical machines, virtual machines (VMs), and cloud instances.
A cloud administrator is implementing Ansible to manage the configuration of remote systems on the cloud network. What type of authentication should the administrator implement with Ansible to ensure that automated processes do not stop while waiting for authentication to complete?
A.Embed the passwords in scripts
B.Password-based authentication
C.Key-based authentication
D.Service accounts
C.Key-based authentication
The administrator should implement key-based authentication so that a password prompt does not stop the automated process. It is also more secure than passwords and does not embed passwords in a script.
Which configuration management tool is appropriate for automating cloud tasks using the concept of “playbooks?”
A.Chef
B.Ansible
C.Puppet
D.PowerShell
B.Ansible
Ansible is a declarative orchestration tool that uses YAML files called playbooks to define the desired configuration. The target system processes the file and configures itself to match by using task-focused modules (such as a Linux yum module for software installation). Ansible is agentless.
An administrator is troubleshooting a failed orchestration job. Where should the administrator check for clues as to why the workflow failed and where to begin troubleshooting efforts?
A.The administrator should check the last successful automation job.
B.The administrator should ensure name resolution services are functional.
C.The administrator should ensure that the SSH key identities match.
D.The administrator should confirm the IP address configuration.
A.The administrator should check the last successful automation job.
The administrator should check the last successful automation job. This will tell the administrator which automation job failed and provide a starting point for troubleshooting the issue.
An administrator upgraded the operating system on several servers and then ran the configuration management tool to ensure the nodes meet the established requirements. However, the configuration management process failed, even though it ran fine earlier that same day. What is a valid reason why the configuration management process may have failed?
A.The version of the configuration management tool is now incorrect.
B.The version of the operating system is now incorrect.
C.The files provided for configuration don’t match the deployment tool.
D.The API version for the backend data source is now incorrect.
B.The version of the operating system is now incorrect.
Since the administrator updated the servers, the version of the operating system is now incorrect and is causing the configuration management process to fail.
An automation task failed to make a change to a Linux virtual instance. The job log recorded an error stating that the account did not have privileges to the remote server. What can the cloud developer check to resolve this problem? (Select all that apply.)
A.Check local private SSH key.
B.Check orchestration workflow sequence.
C.Check assigned service account.
D.Check the last step of the job.
A.Check local private SSH key.
C.Check assigned service account.
Check to ensure the local secure shell (SSH) private key is unchanged. If the key has changed, generate a new set of keys and update the remote Linux server with the public key.
Verify that the automation task uses the correct service account with appropriate permissions to make a change on the remote virtual instance.
A cloud technician is attempting to look for pre-configured automated tasks that are already built. The technician finds some useful YAML files. Which of the following tools is the best option for the technician to use?
A.Chef
B.SDS
C.PowerShell
D.Ansible
D.Ansible
Ansible is a declarative orchestration tool that uses YAML files called Ansible playbooks to define the desired configuration.
A newly configured Ansible workflow job fails midway when trying to reconfigure a virtual instance in the cloud. Other single automation tasks targeting other instances are completing successfully. What can an IT administrator troubleshoot to resolve this issue? (Select all that apply.)
A.Check configuration sequence.
B.Check target’s startup processes.
C.Check target’s automatic IP address.
D.Check target’s DNS record.
A.Check configuration sequence.
B.Check target’s startup processes.
Check the configuration sequence of the workflow, especially if it is a new workflow. Changes in the workflow may require some pre-requisites to complete.
Check the target’s startup processes because the workflow may require certain services to be running to carry out specific changes.
A cloud administrator is researching tools that will ensure the configuration of servers, devices, and services. The administrator is responsible for both Windows and Linux operating systems and does not want to rely on a client-server structure. The administrator also does not want to install agents or enable special services on managed devices. What is the cloud administrator’s best option?
A.Chef
B.Puppet
C.Ansible
D.PowerShell DSC
C.Ansible
The cloud administrator’s best option is Ansible. Ansible is an agentless configuration management tool that connects to devices over Secure Shell (SSH) to manage nodes and configurations and supports both Windows and Linux.
A server technician wants to set up a configuration manager for their server environment through Powershell. Which of the following will help enable them to do this? (Select all that apply.)
A.DSC
B.Glacier
C.MOF
D.Chef
A.DSC
C.MOF
PowerShell can also be used as a configuration manager by enabling and using PowerShell Desired State Configuration (DSC). Using DSC requires that destination systems use PowerShell 4.0 and have remote PowerShell execution enabled.
DSC is a declarative configuration management implementation that relies on a Managed Object Format (MOF) file that holds the configurations

Question
What type of tasks can a cloud administrator automate? (Select all that apply.)
Software updates
Scaling
Restarts
SLA
A cloud administrator can automate the deployment of software updates. Automating software updates will make the process both faster and consistent across all devices.
Automating scaling can ensure that applications have just enough resources at all times. Cloud administrators can set thresholds for both scaling up and scaling back on resources as needed.
Cloud administrators can use automation to restart systems. The administrator must configure the automation tool agent to start automatically so that it is available after a reboot.
In preparation for patching the operating systems on a cloud network, the administrator double-checked to make sure the correct patch was queued for the operating system, that it was the correct version, and that it tested successfully in the test environment. However, the patch still failed to install in production. What are some reasons why the patch installation may have failed? (Select all that apply.)
A.The administrator failed to ensure that there was sufficient drive space available for the patch process.
B.The administrator failed to ensure the patch matched the application version.
C.The administrator failed to test the patch in the production environment.
D.The administrator failed to disable antivirus during the patching process.
A.The administrator failed to ensure that there was sufficient drive space available for the patch process.
D.The administrator failed to disable antivirus during the patching process.
he patch installation may have failed since the administrator failed to ensure there was sufficient drive space available for the patching process in the production environment.
The patch may have failed since the administrator failed to disable antivirus during the patching process in the production environment. Antivirus programs can block the installation of patches.
An administrator is updating the routers in the cloud environment by making a scripted set of changes with code and then applying the changes to all the routers. What is this approach known as?
A.DevOps
B.CI/CD
C.IaaS
D.IaC
D.IaC
IaC (Infrastructure as Code) is the term used when administrators configure resources by scripting the configuration in code and deploying it through automation.
An administrator scripted all the steps needed to create and deploy new database servers for the organization’s applications. After the administrator tested the scripts to ensure they worked properly, the administrator then created a workflow to start and run all the automated steps in order. What is this an example of?
A.Configuration management
B.Automation
C.Orchestration
D.Sequencing
C.Orchestration
Orchestration involves sequencing multiple, automated steps in the correct order into a single workflow that can run the entire process from start to finish.
