A _______ is a database object that automatically triggers specific actions when certain events occur in the database.
- Index
- Procedure
- Trigger
- View
In the context of databases, a 'trigger' is an object that automatically initiates specific actions when predefined events, such as data changes or updates, occur in the database. Triggers help maintain data integrity and enforce business rules.
You are setting up a network for a small business. They want to ensure that even if one of the network paths fails, there will be another path available for data to travel. Which type of routing should you consider implementing?
- Default Routing
- Dynamic Routing
- Load Balancing
- Static Routing
In this scenario, implementing 'Dynamic Routing' is the most suitable choice. Dynamic routing protocols like OSPF or EIGRP allow routers to automatically update routing tables, making it possible for data to take alternative paths in case of network path failures.
What is the main purpose of a "tokenizer" in Natural Language Processing?
- Converting text to speech
- Counting words
- Identifying emotions
- Splitting text into words
A "tokenizer" in NLP is used for 'splitting text into words or tokens.' It breaks down a piece of text into individual words or tokens, which is a fundamental step in many NLP tasks such as text analysis, language modeling, and more.
A company is experiencing slow network speeds during specific times of the day. They suspect it might be a loop in the network. Which tool or protocol can help in detecting and preventing such loops?
- ICMP
- NAT
- SNMP
- Spanning Tree Protocol
To detect and prevent network loops that can lead to slow network speeds, 'Spanning Tree Protocol (STP)' is the right choice. STP is designed to prevent loops in Ethernet networks and ensure a loop-free topology.
How does pipelining improve CPU performance?
- Enhances cache capacity
- Increases clock speed
- Optimizes virtual memory management
- Reduces instruction throughput latency
Pipelining improves CPU performance by reducing instruction throughput latency. It allows multiple instructions to be in different stages of execution simultaneously, thus increasing the overall throughput.
In the realm of HPC, what does "Amdahl's Law" primarily relate to?
- Data compression
- Input/output (I/O) operations
- Memory management
- Parallel processing
"Amdahl's Law" primarily relates to 'parallel processing' in High-Performance Computing (HPC). It quantifies the potential speedup that can be achieved by parallelizing a computation. The law emphasizes that the speedup of a program is limited by the fraction of the code that cannot be parallelized. Understanding Amdahl's Law is essential in optimizing parallel processing in HPC applications.
Which term describes the long-term direction and the broad aims of an organization's IT?
- IT Governance
- IT Operations
- IT Security
- IT Strategy
'IT Strategy' refers to the long-term direction and the broad aims of an organization's IT. It involves defining how IT can support and align with the overall business goals and objectives.
In software engineering, which process model emphasizes iterative development and the rapid construction of prototypes?
- Agile Model
- Spiral Model
- V-Model
- Waterfall Model
The 'Agile Model' emphasizes iterative development and rapid prototyping. It promotes flexibility and customer collaboration during the development process, leading to quicker and more adaptable software delivery.
In a switched network, what technique is used to prevent the broadcast storms that can be caused by switching loops?
- Internet Control Message Protocol (ICMP)
- Routing Information Protocol (RIP)
- Spanning Tree Protocol (STP)
- VLAN Trunking Protocol (VTP)
To prevent broadcast storms caused by switching loops in a network, the 'Spanning Tree Protocol (STP)' is employed. STP helps in determining a loop-free path through the switched network and blocks redundant links to prevent loops.
What is the primary goal of information assurance?
- Ensuring data accuracy
- Maximizing data size
- Protecting data
- Storing data securely
The primary goal of information assurance is 'protecting data.' Information assurance focuses on safeguarding the confidentiality, integrity, and availability of data and information assets.
