A systems administrator is planning to migrate to a cloud solution with volume-based licensing. Which of the following is most important when considering licensing costs?
Correct Answer:
C
Volume-based licensing is a model where the cost of the software is based on the number of licenses purchased1. This model is commonly used for software that is installed on a specific number of devices, such as antivirus software or office productivity suites1. Therefore, the number of machines is the most important factor when considering licensing costs in this model.

A systems administrator deployed a new web application in a public cloud and would like to test it, but the company's network firewall is only allowing outside connections to the cloud provider network using TCP port 22. While waiting for the network administrator to open the required ports, which of the following actions should the systems administrator take to test the new application? (Select two).
Correct Answer:
BF
To test the new web application in the public cloud, the systems administrator should create a replica database, synchronize the data, and switch to the new instance, and create a SSH tunnel. Creating a replica database can help minimize the downtime and ensure data consistency during the migration. Synchronizing the data can help keep the replica database up to date with the original database. Switching to the new instance can help activate the new web application in the public cloud. Creating a SSH tunnel can help bypass the network firewall and access the web application using TCP port 22. SSH is a secure protocol that can create encrypted tunnels between the local and remote hosts. By creating a SSH tunnel, the systems administrator can forward the web application traffic through the tunnel and test it using a web browser.

A company has developed a cloud-ready application. Before deployment, an administrator needs to select a deployment technology that provides a high level of portability and is lightweight in terms of footprint and resource requirements.
Which of the following solutions will be BEST to help the administrator achieve the requirements?
Correct Answer:
A
Containers are a type of deployment technology that packages an application and its dependencies into a lightweight and portable unit that can run on any platform or environment. Containers can provide a high level of portability and are lightweight in terms of footprint and resource requirements, as they do not need a full operating system or hypervisor to run. Containers can also enable faster and easier deployment, scaling, and management of cloud-based applications. Containers are the best solution to help the administrator achieve the requirements for deploying a cloud- ready application.

A systems administrator is planning a penetration test for company resources that are hosted in a public cloud. Which of the following must the systems administrator do FIRST?
Correct Answer:
D
The first thing that the systems administrator must do before planning a penetration test for company resources that are hosted in a public cloud is to consult the cloud services provider’s policies and guidelines. Penetration testing is a type of security assessment that involves simulating an attack on a system or network to identify vulnerabilities and weaknesses. However, not all cloud services providers allow penetration testing on their platforms, or they may have specific rules and requirements for conducting such tests. The systems administrator should check the cloud services provider’s policies and guidelines and obtain their permission and approval before performing any penetration testing.

A systems administrator is using VMs to deploy a new solution that contains a number of application VMs.
Which of the following would provide high availability to the application environment in case of hypervisor failure?
Correct Answer:
A
Anti-affinity rules are rules or policies that prevent two or more VMs from running on the same host or cluster in a cloud environment. Anti-affinity rules can provide high availability to an application environment in case of hypervisor failure, as they can distribute or separate the application VMs across different hosts or clusters and avoid having a single point of failure. Anti-affinity rules can also improve performance and reliability, as they can reduce contention and load by balancing the resource utilization across multiple hosts or clusters.
