UPDATE || 100% GUARANTEED PASS
1. According to the NIST definition of cloud computing, which characteristic refers to the
ability to automatically provision resources without requiring human interaction with the
service provider?
A. On-demand self-service
B. Resource pooling
C. Broad network access
D. Rapid elasticity
Answer: A
Conceptual Explanation: On-demand self-service allows users to provision computing
capabilities as needed automatically without human intervention.
2. Which type of hypervisor runs directly on the underlying host hardware rather than on top
of an operating system?
A. Type 2 Hypervisor
B. Para-virtualized Hypervisor
,C. Type 1 Hypervisor
D. Hosted Hypervisor
Answer: C
Conceptual Explanation: Type 1 hypervisors, also known as bare-metal hypervisors, run
directly on the host’s hardware to manage guest operating systems.
3. A system administrator needs to implement a RAID level that provides high redundancy
and performance by striping data across mirrored pairs. Which RAID level should they use?
A. RAID 5
B. RAID 1
C. RAID 10
D. RAID 6
Answer: C
Conceptual Explanation: RAID 10 (or 1+0) combines the mirroring of RAID 1 with the
striping of RAID 0, providing both redundancy and high performance.
4. In the OSI model, which layer is responsible for routing packets across different networks
using logical addressing?
A. Data Link Layer
B. Transport Layer
C. Network Layer
, D. Session Layer
Answer: C
Conceptual Explanation: The Network Layer (Layer 3) handles logical addressing (IP
addresses) and routing of data packets between different networks.
5. What is the primary difference between a Storage Area Network (SAN) and Network
Attached Storage (NAS)?
A. SAN provides file-level access while NAS provides block-level access.
B. SAN provides block-level access while NAS provides file-level access.
C. SAN uses Ethernet while NAS only uses Fiber Channel.
D. NAS is more expensive and complex to maintain than SAN.
Answer: B
Conceptual Explanation: NAS typically provides file-level access via protocols like NFS or
SMB, whereas SAN provides block-level access, often appearing as a local drive.
6. When a CPU switches from executing one process to another, the state of the current
process is saved and the state of the next process is loaded. What is this process called?
A. Context Switching
B. Process Migration
C. Interrupt Handling
D. Scheduling
