• Question 202:

  A cloud administrator received a request to provision a set of cloud resources in an effort to switch to infrastructure as code to automate and optimize operations. The administrator decides to try to run some tests with the following definition:

  

  Which of the following is the most likely cause of the issue?

  A. The cloud provider is expecting the private key.
  B. The incorrect resource name was used.
  C. The environment variable for the public key path has not been set.
  D. An unexpected variable was provided.
  C. The environment variable for the public key path has not been set.

  ---

  Explanation

  The error message indicates that the cloud provider is unable to find the public key file that is specified in the definition. The definition uses an environment variable called PUBLIC_KEY_PATH to refer to the location of the public key file. However, if this environment variable has not been set or exported in the shell, the cloud provider will not be able to resolve it and will fail to provision the resources. To fix this issue, the cloud administrator should set and export the environment variable for the public key path before running the definition.

• Question 203:

  A cloud solutions architect has an environment that must only be accessed during work hours. Which of the following processes should be automated to BEST reduce cost?

  A. Scaling of the environment after work hours
  B. Implementing access control after work hours
  C. Shutting down the environment after work hours
  D. Blocking external access to the environment after work hours
  C. Shutting down the environment after work hours

  ---

  Explanation

  One of the main benefits of cloud computing is that you only pay for the resources that you use. However, this also means that you need to manage your cloud resources efficiently and avoid paying for idle or unused resources1. Shutting down the environment after work hours is a process that can be automated to best reduce cost in a cloud environment that must only be accessed during work hours. This process involves stopping or terminating the cloud resources, such as virtual machines, databases, load balancers, etc., that are not needed outside of the work hours. This can significantly reduce the cloud bill by avoiding charges for compute, storage, network, and other services that are not in use2. The other options are not the best processes to automate to reduce cost in this scenario: Option A: Scaling of the environment after work hours. Scaling is a process that involves adjusting the number or size of cloud resources to match the demand or workload. Scaling can be done manually or automatically using triggers or policies. Scaling can help optimize the performance and availability of a cloud environment, but it does not necessarily reduce the cost. Scaling down the environment after work hours may reduce some costs, but it may still incur charges for the remaining resources. Scaling up the environment before work hours may increase the cost and also introduce delays or errors in provisioning new resources3. Option B: Implementing access control after work hours. Access control is a process that involves defining and enforcing rules and policies for who can access what resources in a cloud environment. Access control can help improve the security and compliance of a cloud environment, but it does not directly affect the cost. Implementing access control after work hours may prevent unauthorized access to the environment, but it does not stop or terminate the resources that are still running and consuming cloud services4. Option D: Blocking external access to the environment after work hours. Blocking external access is a process that involves restricting or denying network traffic from outside sources to a cloud environment. Blocking external access can help protect the environment from potential attacks or breaches, but it does not impact the cost. Blocking external access after work hours may prevent unwanted requests or connections to the environment, but it does not shut down or release the resources that are still active and generating cloud charges.

• Question 204:

  Several users are able to access internal company resources with corporate credentials; however, when they try to log in to external SaaS applications, the users are redirected back to the log-in page. Which of the following is the most likely cause of the issue?

  A. The SaaS provider is experiencing an outage with its directory service.
  B. A new company policy requires all users to reset their passwords.
  C. MFA (Multi-Factor Authentication) on the internal company authentication service is misconfigured.
  D. The SSL certificate on the external SaaS application has expired.
  E. A new security policy has disabled cookies on users' browsers.
  E. A new security policy has disabled cookies on users' browsers.

• Question 205:

  An administrator recently provisioned a file server in the cloud. Based on financial considerations, the administrator has a limited amount of disk space. Which of the following will help control the amount of space that is being used?

  A. Thick provisioning
  B. Software-defined storage
  C. User quotas
  D. Network file system
  C. User quotas

  ---

  Explanation

  User quotas are what will help control the amount of space that is being used by a file server in the cloud that has a limited amount of disk space due to financial considerations. User quotas are the limits or restrictions that are imposed on the amount of space that each user can use or consume on a file server or storage device. User quotas can help to control the amount of space that is being used by: Preventing or reducing wastage or overuse of space by users who may store unnecessary or redundant files or data on the file server or storage device. Ensuring fair and equal distribution or allocation of space among users who may have different needs or demands for space on the file server or storage device. Monitoring and managing the usage or consumption of space by users who may need to be notified or alerted when they reach or exceed their quota on the file server or storage device.

• Question 206:

  All of a company's servers are currently hosted in one cloud MSP. The company created a new cloud environment with a different MSP. A cloud engineer is now tasked with preparing for server migrations and establishing connectivity between clouds. Which of the following should the engineer perform FIRST?

  A. Peer all the networks from each cloud environment.
  B. Migrate the servers.
  C. Create a VPN tunnel.
  D. Configure network access control lists.
  C. Create a VPN tunnel.

  ---

  Explanation

  Creating a VPN tunnel is the first action that the engineer should perform to prepare for server migrations and establish connectivity between clouds. A VPN (Virtual Private Network) tunnel is a secure and encrypted connection that allows data to be transferred between two networks or locations over the public internet. Creating a VPN tunnel can enable communication and interoperability between different cloud environments, as well as protect data from interception or modification during migration.

• Question 207:

  A. Chain of custody
  B. Root cause analysis
  C. Playbook
  D. Call tree
  D. Call tree

  ---

  Explanation

  A call tree is what will help the administrator find the details of the relevant team members for escalation after a disaster situation has occurred and the entire team needs to be informed about the situation. A call tree is a document or diagram

  that shows the hierarchy or sequence of communication or notification among team members in case of an emergency or incident, such as a disaster situation. A call tree can help to find the details of the relevant team members for escalation

  by providing information such as:

  Name: This indicates who is involved in the communication or notification process, such as team members, managers, stakeholders, etc. Role: This indicates what is their function or responsibility in the communication or notification process,

  such as initiator, receiver, sender, etc. Contact: This indicates how they can be reached or contacted in the communication or notification process, such as phone number, email address, etc.
