Correct Answer(s)
B. Zastita i replikovanje podataka je jedno od prednosti NAS skladista
D. DAS skladiste se direktno povezuje na uredjaj, bez koriscenja racunarske mrezeExplanation
The correct answer is "Zastita i replikovanje podataka je jedno od prednosti NAS skladista" and "DAS skladiste se direktno povezuje na uredjaj, bez koriscenja racunarske mreze". The first statement states that data protection and replication is one of the advantages of NAS storage. NAS (Network Attached Storage) allows for centralized data storage and can provide data protection mechanisms such as RAID and backup solutions. The second statement states that DAS (Direct Attached Storage) is directly connected to the device without using a computer network. DAS storage is typically connected via USB, SATA, or other direct interfaces.Rate this question:

- F.
RAID 5, RAID 1, RAID 0
Correct Answer
B. RAID 1, RAID 5, RAID 0Explanation
The correct answer is RAID 1, RAID 5, RAID 0. This is because RAID 1 (mirroring) offers the slowest speed as it requires writing data to two drives simultaneously. RAID 5 (striping with parity) offers better speed as it distributes data and parity information across multiple drives. RAID 0 (striping without parity) offers the fastest speed as it splits data across multiple drives without any redundancy. Therefore, the correct order of RAID implementations from slowest to fastest is RAID 1, RAID 5, RAID 0.Rate this question:

- D.

- F.
300 GB
- G.
250 GB
Correct Answer
B. 400 GBExplanation
When creating a RAID 5 with 5 disks, each with a capacity of 100 GB, the effective storage space will be 400 GB. In RAID 5, one disk is used for parity, which allows for data recovery in case of a disk failure. Therefore, the usable storage space is equal to the sum of the capacities of all the disks minus one disk for parity, resulting in 400 GB.Rate this question:

D. Kao jedna od prednosti NAS skladista navodi se balans podatakaExplanation
The given answer states that in object-based implementations of storage, data (such as files) are matched with the data of the applications that use that storage, creating storage objects. This statement is incorrect because in object-based storage, data is organized and accessed based on unique identifiers rather than being paired with application data. Additionally, the answer mentions that one of the advantages of NAS storage is data balancing, which is also incorrect. NAS storage does not typically involve data balancing, as it is a file-level storage system.Rate this question:

The correct answer is "NETACNO" which means "FALSE" in English. This suggests that classical VLAN networks are not mobile. VLANs (Virtual Local Area Networks) are used to logically divide a single physical network into multiple virtual networks. However, VLANs are not inherently mobile as they are typically configured on switches and do not move with devices or users. To provide mobility in a network, additional technologies such as VLAN tagging or dynamic VLAN assignment may be used.Rate this question:

Correct Answer
C. Memory overcommittingExplanation
Memory overcommitting is a function that allows virtual machines running on top of a hypervisor to use more RAM than what is physically installed on the server. This is achieved by dynamically allocating memory resources to virtual machines based on their current usage and demands. By overcommitting memory, the hypervisor can optimize resource utilization and allow for more efficient allocation of memory among virtual machines.Rate this question:

Memory ballooning is a function that allows the hypervisor to reclaim unused memory from a virtual machine that is running on top of it. This technique involves inflating or "ballooning" a balloon driver inside the guest operating system, which requests the guest to release some of its memory back to the hypervisor. By reclaiming unused memory, the hypervisor can allocate it to other virtual machines or use it for other purposes, improving overall system efficiency and resource utilization.Rate this question:

In RAID 1+0 implementation, also known as RAID 10, data is mirrored and striped across multiple disks. This means that if one disk fails, the system can still function because the data is replicated on another disk. However, if two disks fail simultaneously, the system will not be able to continue functioning because there will be no redundant copies of the data available.

The correct answer is "aktivan/u pripravnoti, aktivan/aktivan." High availability of cloud resources is achieved by using redundant systems that operate in two modes: active/standby and active/active. In the active/standby mode, one system is actively serving requests while the other is on standby, ready to take over in case of failure. In the active/active mode, both systems are actively serving requests simultaneously, distributing the workload between them.

Correct Answer
D. Prvo migrirati manje sisteme, a zatim migraciju sprovoditi inkrementalno tokom vremenaExplanation
The correct answer suggests that one of the principles to increase the likelihood of a successful migration of systems and equipment to the cloud is to first migrate smaller systems and then gradually migrate larger systems over time. This approach allows for a more manageable and controlled migration process, minimizing potential risks and ensuring that the migration is carried out smoothly. By starting with smaller systems, any issues or challenges can be addressed and resolved before moving on to larger and more critical systems. Incrementally migrating systems over time also allows for adjustments and optimizations based on business needs and requirements.Rate this question:
