Which type of visualization would be most appropriate for representing hierarchical data, like the structure of an organization?
- Bar Chart
- Pie Chart
- Scatter Plot
- Tree Diagram
Representing hierarchical data, such as the structure of an organization, is best done using a 'Tree Diagram' visualization. It visually displays the parent-child relationships between different levels of a hierarchy, making it clear and organized.
Which data structure would be most efficient for implementing a cache with least recently used (LRU) eviction policy?
- Binary Search Tree
- Doubly Linked List
- Hash Table
- Priority Queue
A 'Doubly Linked List' is a common choice for implementing an LRU cache. It allows efficient insertion and removal of elements from both ends, making it suitable for the LRU policy.
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.
You are tasked with setting up a hybrid cloud for your organization. What would be a primary concern regarding network communication between the on-premises environment and the cloud?
- Data Security
- Energy Efficiency
- Latency
- Scalability
In a hybrid cloud, 'latency' is a primary concern because it refers to the delay in data transmission between on-premises and cloud environments. High latency can affect performance and user experience.
In web development, which protocol is primarily used for secure communication over a computer network?
- FTP
- HTTP
- HTTPS
- SMTP
'HTTPS' stands for Hypertext Transfer Protocol Secure and is used for secure communication over computer networks, especially in web development. It ensures data encryption and secure data transmission.
Which platform-specific language is primarily used for iOS app development?
- C++
- Java
- Python
- Swift
Swift is the primary language for iOS app development. It offers a clean and efficient way to build applications for Apple's ecosystem, making it the preferred choice for iOS developers.
A company is implementing a new ERP system. Midway through the project, they realize that the chosen software doesn't align with some of their core business processes. What should the company consider doing next?
- Abandon the project and start from scratch with a more suitable ERP system.
- Conduct a thorough analysis to identify necessary adjustments and modifications to the chosen ERP system.
- Continue with the current software and modify the business processes to fit.
- Develop custom software to bridge the gap.
In this scenario, the company should conduct a thorough analysis to identify the misalignment between the ERP system and its core business processes. This will help in making informed decisions on necessary adjustments and modifications to ensure a successful implementation.
In NoSQL databases, _______ is a system for storing data in flexible, schema-less documents rather than in traditional tables.
- BSON
- DocumentDB
- JSON
- XML
In NoSQL databases, data is often stored in flexible, schema-less documents, and JSON (JavaScript Object Notation) is a widely used format for this purpose. JSON allows for easy data representation and storage.
A routing technique where packets can take multiple paths to reach the destination, thus providing load balancing, is called _______.
- Anycast
- Multicast
- Multipath
- Unicast
The routing technique that allows packets to take multiple paths to reach the destination for load balancing and redundancy is known as 'Multipath' routing. This is commonly used in modern network architectures.
