37. A network administrator is establishing Layer 3 connectivity between Layer 2 segments. Which of the following does the administrator need to complete this task?
Answer: C
SVI is necessary for Layer 3 connectivity between Layer 2 segments.
To establish Layer 3 connectivity between Layer 2 segments, the network administrator needs to configure a Switched Virtual Interface (SVI). An SVI allows for routing between VLANs and enables Layer 3 communication on a switch.
A) VIP
A Virtual IP (VIP) is used in scenarios involving load balancing or failover solutions, but it does not facilitate Layer 3 connectivity between Layer 2 segments. Therefore, it is not relevant for the task at hand.
B) NAT
Network Address Translation (NAT) is primarily used for translating private IP addresses to public ones and vice versa. It does not directly establish Layer 3 connectivity between Layer 2 segments; thus, it is not the correct choice for this scenario.
C) SVI
A Switched Virtual Interface (SVI) is a virtual interface that provides Layer 3 IP addressing for VLANs on a switch. Configuring an SVI is essential for enabling routing between different VLANs, making it the correct choice for establishing Layer 3 connectivity between Layer 2 segments.
D) 802.1Q tagging
802.1Q tagging is a method used to identify and segregate VLAN traffic on a network. While it is important for ensuring that traffic is properly tagged between switches, it does not itself provide Layer 3 connectivity. Therefore, it does not fulfill the requirements of establishing Layer 3 communication.
Conclusion
The necessity of configuring an SVI for Layer 3 connectivity between Layer 2 segments is clear, as it allows for the routing of traffic between VLANs. Options A, B, and D do not provide the required functionality, making SVI the definitive choice for the network administrator's task.
