Which of the following is a traditional method of project management characterized by a linear and sequential approach?
- Agile
- DevOps
- Scrum
- Waterfall
The 'Waterfall' model is a traditional project management approach that follows a linear and sequential process, where each phase must be completed before moving on to the next. It's a structured approach often used in large projects.
In NLP, _______ is a type of model that can predict the next word in a sequence.
- CNN
- LSTM
- RNN
- Transformer
In NLP (Natural Language Processing), a 'Transformer' model is a type of deep learning model used for tasks like predicting the next word in a sequence, language translation, and more.
In OSPF, the database that contains information about the network's topology is called the _______ database.
- BGP
- Link-State
- Routing
- Routing Table
In OSPF (Open Shortest Path First), the database containing information about the network's topology is known as the 'Link-State' database. This database helps routers build a complete and accurate view of the network.
Which framework is widely recognized for IT governance and management practices?
- Agile
- COBIT
- JavaScript
- Python
COBIT (Control Objectives for Information and Related Technologies) is a globally recognized framework for IT governance and management. It provides best practices for organizations to manage and govern their IT processes and assets.
Which algorithmic technique involves breaking a problem down into smaller and smaller subproblems until the subproblems become simple enough to be solved directly?
- Binary Search
- Divide and Conquer
- Greedy Algorithm
- Heuristic Search
The 'Divide and Conquer' technique involves recursively breaking down a complex problem into smaller subproblems until they become simple to solve directly. It's a common approach in algorithm design.
You are tasked with ensuring that a mobile app's user data remains consistent across multiple devices. Which database feature or principle would be critical to implement?
- ACID Transactions
- CAP Theorem
- MapReduce
- Sharding
To maintain data consistency across multiple devices, you should implement 'ACID transactions' (Atomicity, Consistency, Isolation, Durability). ACID transactions ensure that data changes are either fully completed or fully undone, preventing inconsistencies.
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 formal statement in an organization that defines allowable and safe use of IT resources is called a(n) _______.
- IT Policy
- IT Protocol
- IT Protocol
- IT Regulation
In an organization, a formal statement that defines the allowable and safe use of IT resources is referred to as an 'IT Policy.' IT policies set guidelines and standards for the use of technology within the organization.
