The main reason for the transition from IPv4 to IPv6 is (a)  

• IPv4 addresses are running out

• IPv4 is too slow

• IPv4 is not secure

• IPv4 is too expensive

Answer explanation

The main reason for transitioning from IPv4 to IPv6 is that IPv4 addresses are running out. IPv6 provides a vastly larger address space, accommodating the growing number of devices connected to the internet.

What does Moore's law describe?

• The lifespan of software

• The cost of hardware

• The speed of computers

• The natural progression of technology

Answer explanation

Moore's law describes the natural progression of technology, specifically the observation that the number of transistors on a microchip doubles approximately every two years, leading to increased performance and efficiency.

What are legacy systems?

• Outdated computer systems

• Systems that are open-source

• Newly developed systems

• Systems with the latest technology

Answer explanation

Legacy systems refer to outdated computer systems that are still in use, often because they perform essential functions despite being based on older technology. This makes 'Outdated computer systems' the correct choice.

What is a common issue during business mergers?

What is Software-as-a-Service (SaaS)?

• A type of hardware

• A software licensing and delivery model

• A network protocol

• A programming language

Answer explanation

Software-as-a-Service (SaaS) is a software licensing and delivery model where applications are hosted in the cloud and accessed via the internet, rather than being installed on local devices.

What is a disadvantage of SaaS?

• Limited functionality

• Complex installation

• High maintenance costs

• Security problems

Answer explanation

A significant disadvantage of SaaS is security problems, as sensitive data is often stored on third-party servers, increasing the risk of breaches compared to on-premises solutions.

What does Network-as-a-Service (NaaS) provide?

• Software development tools

• Network transport connectivity

• User interface design

• Data storage solutions

Answer explanation

Network-as-a-Service (NaaS) provides network transport connectivity, allowing users to access and manage network resources over the internet, rather than relying on physical infrastructure.

What is parallel running in system installation?

• Using only the new system

• Replacing the old system immediately

• Running both old and new systems simultaneously

• Testing the system in a lab

Answer explanation

Parallel running involves operating both the old and new systems at the same time. This approach allows for comparison and ensures that the new system is functioning correctly before fully transitioning away from the old system.
