Answer:
Infrastructure as a service (IaaS)
Explanation:
<em>Cloud computing</em> is the provision of computer resources (such as computing power and storage) to users without the need for them to manage these resources. Cloud resources can be deployed to one organization or multiple organizations at the same time. Companies who are cloud provides usually use the pay-as-you-go method of billing customers, hence the need for system administrators to be familiar with cloud pricing methods.
There are several <em>service models</em> for Cloud computing, they are:
- Infrastructure as a service (IaaS)
- Software as a service (SaaS)
- Platform as a service (PaaS)
- Mobile Backend as a service (MBaaS)
- Function as a service (FaaS) and
- Serverless Computing.
<em>Infrastructure as a service (IaaS)</em> is a cloud service model that provides physical computing resources, networking components, servers, storage and so on. Resources containing large categories of equipment are made available to users from data centers. Operating Systems and application software are installed on the cloud infrastructure bought.
Answer:
The answer is below
Explanation:
The various stages in the information processing cycle in the correct order is as follows:
1. Input stage: this is when the data is sent into the computer through the hardware
2. Processing stage: this when the is being refined in the central processing unit of the computer
3. Storage stage: this is when the data is being saved or stored in the computer memory such as Hard drive or external storage such as Flash drive
4. Output stage: this is when the refined or processed data is produced to the user either through the monitor screen or printing
Answer:
For dynamic disks, the term volume is used to define the space where a file system in installed.
Explanation:
A volume is defined as the storage area extracted from free space or say unused space. A file system is used to format a volume or to assign it a drive name.
Five types of volumes are supported by dynamic disks. They are as follows:
- Simple Volumes
- Mirrored volumes
- Striped volumes
- Spanned volumes
- RAID-5 volumes
Answer:
D.
Explanation:
Based on the information provided surrounding this scenario, it can be said that the most likely next course of action would be to create an alternate user ID to maintain persistent access. This would allow the attacker to have continuous access into the network in the case that the system administrators detect that the operator's user ID and password have been compromised. Thus also giving the attacker ample time to infiltrate and find vulnerabilities in the network through an alternate hidden user ID.
