Explain the difference between interior and exterior routing protocols.

• Interior protocols are used for routing within a network, while exterior protocols route between networks.
• Interior protocols route between networks, while exterior protocols are used for routing within a network.
• Interior protocols use more resources, while exterior protocols are more efficient.
• Interior protocols are less secure, while exterior protocols have higher security measures.

What are the basic components of MPLS Architecture?

• MPLS Router, MPLS Switch, MPLS Label
• MPLS Label, MPLS LSR, MPLS LER
• MPLS LSR, MPLS VPN, MPLS Label
• MPLS LER, MPLS Switch, MPLS VPN

Describe the function of the control plane and data plane in a router.

• The control plane is responsible for routing while the data plane forwards data packets.
• The data plane is responsible for routing while the control plane forwards data packets.
• The control plane controls the input and output of data, while the data plane manages the CPU.
• The data plane controls the input and output of data, while the control plane manages the CPU.

What is the purpose of the BGP 'next-hop-self' command?

• It is used to specify that the next hop should be the IP address of the neighboring router.
• It forces the router to become the next hop in the BGP updates it sends.
• It shows the next hop information in the BGP table.
• It sets the local router as the next hop.

In EIGRP, what is the purpose of a 'feasible successor'?

• It is the second-best route to a remote network.
• It is the best route to a remote network.
• It is the route that is currently being used to forward traffic.
• It is the backup route in case the primary route fails.

Can you explain how QoS can be implemented in a network and why it is important?

• By prioritizing certain types of data, making sure important data gets through first.
• By eliminating all non-essential data from the network.
• By increasing the speed at which all data travels through the network.
• By decreasing the amount of data that
