What cryptographic technique allows multiple parties to compute a function over their inputs while keeping those inputs private?
- Digital Signatures
- Public Key Infrastructure (PKI)
- Secure Multi-Party Computation
- Zero-Knowledge Proof
Secure Multi-Party Computation (SMPC) is a cryptographic technique that enables multiple parties to jointly compute a function over their inputs while ensuring the privacy of those inputs. It's used in scenarios where data privacy is crucial, such as collaborative data analysis without revealing individual data points.
One of the pillars of IT governance is ensuring that IT resources are used responsibly, efficiently, and _______.
- Effectively
- Innovatively
- Securely
- Transparently
In IT governance, one of the pillars is to ensure that IT resources are used responsibly, efficiently, and 'transparently.' This means that actions and decisions related to IT should be clear and open to scrutiny, promoting accountability and trust.
Which module in an ERP system typically manages human resources, payroll, and benefits?
- Finance Module
- HR Module
- Inventory Module
- Sales Module
The 'HR (Human Resources) Module' in an ERP system is responsible for managing various aspects of an organization's human resources, including payroll, employee benefits, and personnel data. It helps streamline HR-related processes.
Which RAID level provides disk mirroring for fault tolerance without striping?
- RAID 0
- RAID 1
- RAID 10
- RAID 5
RAID 1, also known as disk mirroring, is a RAID level that provides fault tolerance by duplicating data on two or more disks. It doesn't involve striping, making it a reliable choice for data redundancy.
High-Performance Computing (HPC) is commonly associated with which type of processing?
- Everyday computing tasks
- Scientific and data-intensive tasks
- Simple mathematical calculations
- Social media management
High-Performance Computing (HPC) is associated with "scientific and data-intensive tasks." These tasks involve complex simulations, modeling, and data analysis that require immense computational power, often beyond the capability of regular computers.
Which activation function in neural networks maps its input to values between 0 and 1?
- Leaky ReLU
- ReLU (Rectified Linear Unit)
- Sigmoid
- Tanh (Hyperbolic Tangent)
The activation function that maps its input to values between 0 and 1 is the 'Sigmoid' function. It's commonly used in the output layer of a neural network for binary classification tasks, where it represents probabilities.
Which protocol operates at the Data Link layer and prevents loops in Ethernet networks by creating a loop-free logical topology?
- ARP
- ICMP
- OSPF
- STP
The Spanning Tree Protocol (STP) operates at the Data Link layer and prevents loops in Ethernet networks by creating a loop-free logical topology. It's crucial for network stability and redundancy in Ethernet networks.
_______ is a virtualization technology focused on running multiple instances or copies of an application on a single set of hardware resources.
- Containerization
- Firewall
- Hyperconvergence
- Virtual Private Network (VPN)
'Containerization' is a virtualization technique that allows running multiple instances or copies of applications on the same hardware, isolated from each other. Containers share the same OS kernel and use fewer resources.
What SQL clause is used to filter the results of a query based on a specified condition?
- GROUP BY
- ORDER BY
- SELECT
- WHERE
The 'WHERE' clause in SQL is used to filter the results of a query based on a specified condition. It allows you to retrieve specific data that meets certain criteria.
You have a list of tasks to complete, some of which depend on others being completed first. You want to determine a sequence to complete the tasks such that all dependencies are honored. What algorithmic approach would be most suitable?
- Greedy Algorithm
- Merge Sort
- Quick Sort
- Topological Sorting
To determine a task sequence while honoring dependencies, 'Topological Sorting' is the most appropriate approach. It is commonly used in project scheduling and task management to create a linear order of tasks in a directed acyclic graph (DAG) while ensuring all dependencies are met.
