Which statement explains why Type 1 hypervisor is considered more efficient than Type 2 hypervisor?

• A.Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS.
• B.Type 1 hypervisor enables other operating systems to run on it.
• C.Type 1 hypervisor relics on the existing OS of the host machine to access CPU, memory, storage, and network resources.
• D.Type 1 hypervisor is the only type of hypervisor that supports hardware acceleration techniques.

Correct Answer: A

Explanation
There are two types of hypervisors: type 1 and type 2 hypervisor.
In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server. Then instances of an operating system (OS) are installed on the hypervisor. Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V.
In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. answer 'Type 1 hypervisor runs directly on the physical hardware of the host machine without relying on the underlying OS' big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows).

What is the JSON syntax that is formed from the data?

• A.Make":'Gocar, "Model': "Zoom", "Features": ["Power Windows", "Manual Dnve", "Auto AC"]}
• B.'Make ": "Gocar1, "Model": "Zoom", "Features": ["Power Windows", "Manual Drive", "Auto AC"]
• C.{"Make": Gocar, "Model": Zoom, "Features": Power Windows, Manual Drive, Auto AC}
• D.("Make":[ "Gocar", "Model": "Zoom"], Features": ["Power Windows", "Manual Drive", "Auto AC"]}

Correct Answer: A

Explanation
JSON syntax structure: + uses curly braces {} to hold objects and square brackets [] to hold arrays + JSON data is written as key/value pairs + A key/value pair consists of a key (must be a string in double quotation marks ""), followed by a colon :, followed by a value. For example: "name":"John" + Each key must be unique + Values must be of type string, number, object, array, boolean or null + Multiple key/value within an object are separated by commas , JSON can use arrays. Arrays are used to store multiple values in a single variable. For example:
{
"name":"John",
"age":30,
"cars":[ "Ford", "BMW", "Fiat"]
}
In the above example, "cars" is an array which contains three values "Ford", "BMW" and "Fiat".
Note: Although our correct answer above does not have curly braces to hold objects but it is still the best choice here.
