The process of reallocating memory for an array when its initial capacity is reached is called _______.
- Dynamic Allocation
- Overloading
- Reallocation
- Serialization
When an array reaches its initial capacity and needs more space, the process of reallocating memory is called 'Reallocation.' This is commonly seen in dynamic arrays or lists.
An algorithm that always takes the same amount of time to process, regardless of the size of the input, has a time complexity of _______.
- O(1)
- O(log?n)
- O(n)
- O(n^2)
An algorithm with a time complexity of O(1) has a constant time of execution, meaning it always takes the same amount of time, regardless of the input size. This is the most efficient time complexity.
An organization is implementing a new ITSM tool. During the Service Transition phase, what should be the primary focus?
- Acquiring new hardware and software.
- Defining the scope of the project.
- Documenting and testing new processes.
- Training employees on the new tool's interface.
In the Service Transition phase of IT Service Management (ITSM), the primary focus should be on documenting and testing new processes. This phase involves preparing for the deployment of new or changed services. It includes activities such as creating documentation, conducting testing, and ensuring that the new ITSM tool integrates seamlessly with existing processes.
In HPC, the ability of a system to scale its performance proportionally with added resources is termed as _______ scalability.
- Chaotic
- Conventional
- Linear
- Static
In High-Performance Computing (HPC), 'Linear' scalability indicates that the system can increase performance proportionally with the addition of resources, a desirable trait in HPC environments.
In the context of computer architecture, the concept where multiple instructions are overlapped in execution is called _______.
- Caching
- Multithreading
- Pipelining
- Superscalar
In computer architecture, 'pipelining' is a technique that allows multiple instructions to overlap in execution stages, enhancing performance by breaking down tasks into smaller stages.
Which technology allows for the creation of virtualized networks, abstracting the physical network infrastructure?
- Artificial Intelligence (AI)
- Blockchain
- Cloud Computing
- Software-Defined Networking (SDN)
'Software-Defined Networking (SDN)' technology abstracts the physical network infrastructure, allowing for the creation of virtualized networks. It separates network control from the data plane, offering greater flexibility and control.
A multinational corporation must ensure that all its global branches adhere to data protection laws of each respective country while also maintaining a unified security posture. Which approach would be most effective in achieving this?
- Centralized Security
- Decentralized Security
- Hybrid Security
- Regional Security
To ensure compliance with different data protection laws globally while maintaining a unified security posture, 'Centralized Security' is the most effective approach. It allows for consistent security policies and controls across all branches.
Within the realm of IT project management, which risk management strategy involves recognizing a potential risk but deciding not to take any action unless the risk occurs?
- Risk Acceptance
- Risk Avoidance
- Risk Mitigation
- Risk Transfer
'Risk Acceptance' is a risk management strategy in which the project team recognizes a potential risk but chooses not to take any proactive action unless the risk actually materializes. This approach is often used for risks with low impact or likelihood.
The technique that helps in understanding the internal mechanisms of complex models in NLP by visualizing the importance of each word is called _______.
- Attention Visualization
- Latent Semantic Analysis (LSA)
- Principal Component Analysis (PCA)
- Word Embedding
The technique referred to in the question is 'Attention Visualization.' It's a method used to visualize the attention scores of each word in an NLP model, particularly in Transformer-based models like BERT. Understanding attention can reveal how models make predictions.
In advanced network troubleshooting, which protocol is used to establish a two-way communication channel over a TCP connection for network management?
- HTTP (Hypertext Transfer Protocol)
- ICMP (Internet Control Message Protocol)
- SNMP (Simple Network Management Protocol)
- SSH (Secure Shell)
In advanced network troubleshooting, 'SSH' (Secure Shell) is used to establish a secure two-way communication channel over a TCP connection. It's commonly used for network management, remote server access, and secure data transfer. SSH provides authentication and encryption.
