Câu 6. Network-attached storage is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. The term “NAS” can refer to both the technology and systems involved, or a specialized device built for such functionality.
- A. True
- B. False
Câu 7. Identify the Cluster: It is a group of computers that are identical and commodity-grade. These are arranged and networked in such a way that they depict a small local area network (LAN). These are programmed such that they share processes among themselves and form parallel processing units. So, Beowulf clusters are parallel computing clusters with high performance. It is a multi-computer architecture that consists of multiple client nodes or workstations and a single server node connected through ethernet or another network.
- A. High Performance Cluster
- B. Active Cluster
- C. Passive Cluster
- D. Beowulf Cluster
Câu 8. Which of the following nodes in Cloud Computing performs this task: Provides “hidden” back-end services such as resource load balancing, administrative/resource databases, security/firewalls, cloud macro management?
- A. Compute Nodes
- B. Storage Nodes
- C. Administrative Nodes
- D. None of these
Câu 9. Amazon EC2, S3 are examples of what type of Cloud Computing Service?
- A. SaaS
- B. DaaS
- C. PaaS
- D. IaaS
Câu 10. Point out the correct statement.
- A. A virtual machine is a computer that is walled off from the physical computer that the virtual machine is running on
- B. Virtual machines provide the capability of running multiple machine instances, each with their own operating system
- C. The downside of virtual machine technologies is that having resources indirectly addressed means there is some level of overhead
- D. All of the mentioned
Câu 11. Identify the Virtualization: It provides a facility to create and provision virtual networks—logical switches, routers, firewalls, load balancer, Virtual Private Network (VPN), and workload security within days or even in weeks. It is a process of logically grouping physical networks and making them operate as single or multiple independent networks called Virtual Networks.
- A. Application
- B. Desktop
- C. Network
- D. Data Virtualization
Câu 12. Identify the layer: It is a layer of programming that allows a computer OS to interact with a hardware device at a general or abstract level rather than at a detailed hardware level. HAL can be called from either the OS’s kernel or from a device driver. In either case, the calling program can interact with the device in a more general way than it would otherwise. Virtualization at this layer exploits the similarity in architectures of the guest and host platforms to cut down the interpretation latency.
- A. Kernal Layer
- B. Guest Layer
- C. Host OS Layer
- D. Hardware Abstraction Layer
Câu 13. Which type of virtualization allows multiple virtual machines to share the same operating system kernel?
- A. Full virtualization
- B. Paravirtualization
- C. Hosted virtualization
- D. Containerization
Câu 14. Identify the Threat: An unauthorized party counterfeits an asset.
- A. Interception
- B. Fabrication
- C. Interruption
- D. Modification
Câu 15. Explain the Attack: It is the act of searching for Wi-Fi wireless networks, usually from a moving vehicle, using a laptop or smartphone.
- A. Warchalking
- B. Man in Middle Attack
- C. Denial of Service
- D. War Driving
Câu 16. Identify the following: A user may use a resource or service without others being able to observe that the resource or service is being used.
- A. Anonymity
- B. Unobservability
- C. Unlinkability
- D. Pseudonymity

- A. Support Agreement
- B. Cloud Service Contract
- C. Service Level Agreement (SLA)
- D. None of these

- A. True
- B. False
Câu 19. Cloud providers have _________ and _________ plans in place to ensure that service can be maintained in case of a disaster or an emergency and that any data lost will be recovered.
- A. Business continuity and project management
- B. Business continuity and data recovery
- C. Business continuity and risk management
- D. None of these
Câu 20. Which of the following is NOT a security benefit of thin clients?
- A. Centralized management and updates
- B. Reduced risk of data theft
- C. Reduced risk of malware infection
- D. Improved performance
