Final answer:
The question is about selecting and upgrading IOS on routers and switches, and the three crucial questions that a network administrator must answer before proceeding.
Step-by-step explanation:
The question is related to the selection and upgrading of IOS on routers and switches. The network administrator must answer three crucial questions before proceeding. These questions include:
- What are the system requirements? This is important to ensure that the chosen IOS version is compatible with the hardware being used.
- Is there compatibility with existing hardware? It is crucial to ensure that the selected IOS version is compatible with the existing hardware in order to avoid any issues or conflicts.
- Are there any potential conflicts with existing software? This question helps identify any conflicts that might arise between the new IOS version and the existing software.
Therefore, the correct answer to the question is c) What are the network security measures in place? While network security is an important aspect, it is not directly related to the selection and upgrading of IOS on routers and switches.
