In mobile app development, what is the term used to describe software that allows you to create apps for multiple platforms using a single codebase?
- Cross-Platform Development
- Hybrid Development
- Native Development
- Platform-Exclusive Development
'Cross-Platform Development' refers to the approach of building mobile apps that work on multiple platforms (e.g., iOS and Android) using a single codebase. It's cost-effective and efficient.
The _______ field in an IPv4 header determines the priority of the packet.
- DSCP
- IP Address
- Protocol
- TTL
The 'DSCP' (Differentiated Services Code Point) field in an IPv4 header is used to determine the priority and class of service for the packet, allowing for quality of service (QoS) differentiation in IP networks.
In a router, the table that keeps track of paths to active networks and how to reach them is known as the _______ table.

You are working on a real-time trading application where the order of transactions is crucial. Which data structure would be most appropriate to ensure that the first transaction entered is the first one processed?
- Binary Tree
- Hash Table
- Queue
- Stack
In real-time trading, the order of transactions is critical. A 'Queue' is the most suitable data structure to ensure the first transaction entered is the first one processed. It follows a First-In-First-Out (FIFO) order, which aligns with transaction sequence requirements.

- Service Blueprint
- Service Catalog
- Service Desk Catalog
- Service Manifesto
The process you're referring to is 'Service Catalog Management.' It's a key component of IT Service Management (ITSM) and involves defining and maintaining the live IT services catalog. This catalog contains information about the available services, ensuring that stakeholders have a clear understanding of the IT services provided.
The SQL command used to modify the structure of an existing table is _______.
- ALTER TABLE
- CHANGE TABLE
- MODIFY TABLE
- UPDATE TABLE
The SQL command 'ALTER TABLE' is used to modify the structure of an existing table, such as adding, deleting, or modifying columns. It's a crucial operation in database management.
Which technique helps prevent overfitting by ignoring certain neurons during training?
- Batch Normalization
- Dropout
- Gradient Clipping
- ReLU Activation Function
The technique that helps prevent overfitting by ignoring certain neurons during training is 'Dropout.' It randomly deactivates neurons, forcing the network to learn more robust representations.
A project's _______ defines the work that needs to be accomplished to deliver a product, service, or result with the specified features and functions.
- Milestone
- Risk Register
- Scope Statement
- Stakeholder Analysis
The 'scope statement' in a project defines the work that must be completed to deliver the project's intended product, service, or result with specified features and functions. It sets the boundaries for the project and helps manage expectations. Milestones are significant project events, the Risk Register records project risks, and Stakeholder Analysis involves identifying and assessing stakeholders.
You are tasked with setting up a public Wi-Fi network for a cafe. Which security measure would be most appropriate to prevent users from seeing the traffic of other users?
- Intrusion Detection System
- MAC Filtering
- VPN Configuration
- WPA3 Encryption
Utilizing WPA3 (Wi-Fi Protected Access 3) encryption is a crucial security measure for a public Wi-Fi network. It encrypts the data between the user's device and the access point, preventing other users from intercepting or seeing the traffic.
In the context of ERP, what is the primary challenge of "data silos"?
- Data duplication
- Data encryption
- Data integration
- Data isolation
"Data silos" in ERP refer to isolated data repositories within an organization, and the primary challenge they pose is 'data integration.' Integrated data is essential for a holistic view of business processes and decision-making.
