2. Which is a characteristic of a Type 1 hypervisor?
- best suited for consumers and not for an enterprise environment
- installed on an existing operating system
- installed directly on a server
- does not require management console software
Explanation: Type 1 hypervisors are installed directly on a server and are known as “bare metal” solutions giving direct access to hardware resources. They also require a management console and are best suited for enterprise environments.
3. Which term is used to describe the process of establishing a connection between any two Bluetooth devices?
- joining
- matching
- pairing
- syncing
Explanation: During the pairing process, a Bluetooth device is set to discoverable mode so as to be detected by another Bluetooth device. Also, a PIN may be requested as part of the pairing process.
4. Which technology virtualizes the network control plane and moves it to a centralized controller?
- cloud computing
- IaaS
- SDN
- fog computing
Explanation: Networking devices operate in two planes: the data plane and the control plane. The control plane maintains Layer 2 and Layer 3 forwarding mechanisms using the CPU. The data plane forwards traffic flows. SDN virtualizes the control plane and moves it to a centralized network controller.
5. What would a technician require in order to install a hypervisor on a client machine?
- virtualization software
- an SSD
- multiple storage drives
- a server housed by a cloud service provider
Explanation: A hypervisor is used to create a virtual machine (VM). The hypervisor can be part of an operating system such as Windows Hyper-V or it can be downloaded from a virtualization vendor such as VMWare or Oracle.
6. A company uses a cloud-based payroll system. Which cloud computing technology is this company using?
- browser as a service (BaaS)
- wireless as a service (WaaS)
- infrastructure as a service (IaaS)
- software as a service (SaaS)
Explanation: There is no such thing as BaaS. Infrastructure as a service (IaaS) is when key network devices such as routers and firewalls are leased from a provider. Wireless as a service (WaaS) is when a provider provides wireless connectivity at a fixed monthly cost.
7. What type of Internet connection would be best for a residence in a remote area without mobile phone coverage or wired connectivity?
- satellite
- dial-up
- cellular
- DSL
Explanation: Satellite Internet service provides the best option for a home user that would otherwise have no Internet connectivity at all. Cellular Internet is only available in areas with mobile phone coverage.
8. Which technology provides a solution for PC virtualization?
- Terminal Services
- hypervisor
- RAID
- server clustering
Explanation: Microsoft provides software, Virtual PC, which is a type of hypervisor that creates and manages virtual machines on a host computer.
9. Which statement describes a characteristic of cloud computing?
- A business can connect directly to the Internet without the use of an ISP.
- Investment in new infrastructure is required in order to access the cloud.
- Applications can be accessed over the Internet through a subscription.
- Devices can connect to the Internet through existing electrical wiring.
Explanation: Cloud computing allows users to access applications, back up and store files, and perform tasks without needing additional software or servers. Cloud users access resources through subscription-based or pay-per-use services, in real time, using nothing more than a web browser.
10. What technology enables a cell phone to be used as a hands-free device?
- Wi-Fi
- Bluetooth
- 4G
- Yosemite
Explanation: Bluetooth provides a way to connect wireless devices, such as headsets, to a nearby mobile device. Wi-Fi and 4G provide WAN access to voice and data. Yosemite is the code name applied to a recent version of Apple OS X.
