Exam SK0-005 topic 1 question 64 discussion

C.. easiest question on the exam. If you don't know this then idk... . The Core installation is a minimalistic installation option that includes only the essential components needed to run the operating system

I believe C is correct. I researched this quite a bit. Then in the book "All-In-One Comptia Server+ Certification" Exam Guide, on page 94 I found what they (CompTia) are looking for. They referred to Server Installation "Methods" and listed "Core" (as well as GUI). Obviously, Core will take less resources. "Bare Metal" is used for better performance and having direct access to the hardware (as you do not share it with other clients). Also (fyi) a Bare Metal Hypervisor is a Bare Metal server but with a Hypervisor installed which also restricts some access to direct hardware (type1 vs type2). Info on that can be found here "https://phoenixnap.com/blog/what-is-bare-metal-server" I do not believe "Bare Metal" is considered a "method" for installing an OS.

Windows Servers Windows servers have traditionally been managed via a GUI. Beginning with Windows Server 2008, Microsoft has offered the Server Core installation option. Server Core is a command line–only OS. It has a much smaller hardware footprint on the server and can provide significant performance benefits. Ref. The Official CompTIA Server+ Study Guide (Exam SK0-005) page 129.

Core is the correct answer, if the question was asked about hypervisor type then we can say it's bare metal. Here, the question was about the OS itself and Core is more rapid and less resources consumption because no GUI, just like a CLI and it's also secure that normal GUI OS

B. Bare metal has access to all the resources

Answer is B bare mental Bare Metal OS installed directly on the server hardware Traditional installation option Resources not shared among multiple installations Provides the security, reliability, and performance required by some industries May be more costly than virtualization
