💡 Hint

Common Mistakes

Choosing 'removes' because it sounds like NFV deletes functions.

Choosing 'duplicates' thinking NFV copies functions.

NFV moves network functions from special hardware devices to software that runs on common servers.

2fill in blank

💡 Hint

Common Mistakes

Choosing 'increases' because of confusion about complexity.

Choosing 'complicates' thinking software is harder to manage.

NFV reduces the time needed to deploy network services by using software instead of hardware.

💡 Hint

Common Mistakes

Choosing 'routers' or 'firewalls' which are hardware devices.

Choosing 'servers' which are physical machines, not software.

The statement is incorrect because NFV replaces hardware with software, often running as virtual machines.

4fill in blank

💡 Hint

Common Mistakes

Confusing NFVI with NFVO roles.

Mixing up VNFs with infrastructure components.

The NFV Infrastructure (NFVI) manages virtual resources, while the NFV Orchestrator (NFVO) handles the orchestration of network services.

💡 Hint

Common Mistakes

Using 'state' instead of 'status' for the value.

Using 'd' or other variables not defined in the loop.

Not transforming the key to uppercase.

This dictionary comprehension creates a new dictionary with keys as uppercase function names (func.upper()), values as their status, iterating over function names (func) that are active.
