A cloud administrator learns that a major version update. 4.6.0. is available for a business-critical application. The application is currently on version 4.5.2. with additional minor versions 3, 4, and 5 available. The administrator needs to perform the update while minimizing downtime.
Which of the following should the administrator do first?

  1. Apply the minor updates and then restart the machine before applying the major update.
  2. During off hours, decommission the machine and create a new one directly on major update 4.6.0.
  3. Stop the service and apply the major updates directly.
  4. Create a test environment and apply the major update

Answer(s): D

Explanation:

The first step the administrator should take is to create a test environment and apply the major update there. This allows for testing the new version without impacting the production environment, thus minimizing downtime and the potential for unexpected issues.


Reference:

Creating test environments and conducting thorough testing before applying updates in production is a risk mitigation strategy covered under cloud deployment and operations in the CompTIA Cloud+ certification.



A software engineer at a cybersecurity company wants to access the cloud environment. Per company policy, the cloud environment should not be directly accessible via the internet.
Which of the following options best describes how the software engineer can access the cloud resources?

  1. SSH
  2. Bastion host
  3. Token-based access
  4. Web portal

Answer(s): B

Explanation:

A bastion host is the best option described for accessing cloud resources without direct internet access. It acts as a secure gateway to access internal networks from external sources and is often used in conjunction with other security measures such as SSH for secure connections.


Reference:

The use of bastion hosts as a secure access point to cloud resources is a security best practice covered in the CompTIA Cloud+ certification's domain on cloud security.



A company requests that its cloud administrator provision virtual desktops for every user. Given the following information:
· One hundred users are at the company.
· A maximum of 30 users work at the same time.
· Users cannot be interrupted while working on the desktop.
Which of the following strategies will reduce costs the most?

  1. Provisioning VMs of varying sizes to match user needs
  2. Configuring a group of VMs to share with multiple users
  3. Using VMs that have spot availability
  4. Setting up the VMs to turn off outside of business hours at night

Answer(s): D

Explanation:

Setting up the VMs to turn off outside of business hours at night will reduce costs the most, especially since a maximum of 30 users work at the same time and users cannot be interrupted while working. This approach ensures that resources are used only when necessary.


Reference:

Cost management and efficient resource utilization strategies like scheduling VMs to turn off during idle times are discussed within the financial management aspects of cloud services in the CompTIA Cloud+ exam objectives.



A user's assigned cloud credentials are locked, and the user is unable to access the project's application. The cloud administrator reviews the logs and notices several attempts to log in with the user's account were made to a different application after working hours.
Which of the following is the best approach for the administrator to troubleshoot this issue?

  1. Create new credentials for the user and restrict access to the authorized application.
  2. Track the source of the log-in attempts and block the IP address of the source in the WAR
  3. Reset the user's account and implement a stronger lock-out policy.
  4. Install an IDS on the network to monitor suspicious activity

Answer(s): B

Explanation:

The administrator should track the source of the log-in attempts and block the IP address in the Web Application Firewall (WAF). This will prevent further unauthorized attempts from that source. It is also advisable to reset the user's account credentials as a precautionary measure.


Reference:

Incident response and addressing unauthorized access attempts, including tracking and blocking IP addresses, are security measures addressed in the CompTIA Cloud+ material.
