For a network running single-area OSPF, how would you decrease the size of the link-state database (LSDB)?

A. B. C. D.D
Option A: Implement RIP as an overlay protocol on all devices This option is not a viable solution because implementing another routing protocol on top of OSPF will not reduce the size of the LSDB. In fact, it would increase the overhead and add more complexity to the network.
Option B: Add more devices to the OSPF network to help with LSDB processing This option is not an effective solution as adding more devices to the network may increase the size of the LSDB and add more processing overhead. Additionally, this solution does not address the root cause of the LSDB size issue.
Option C: Reduce the frequency of hello timers throughout the network This option may help reduce the size of the LSDB because it reduces the frequency of OSPF hello packets being sent and received by the devices. This can result in fewer OSPF updates being generated and thus, smaller LSDB sizes. However, it is important to note that increasing the hello timer interval may also increase the time it takes for the network to detect link failures.
Option D: Implement OSPF areas This option is the most effective solution to reducing the size of the LSDB. OSPF areas allow for the network to be divided into smaller logical segments, with each area maintaining its own LSDB. This reduces the size of the LSDB by limiting the scope of the LSAs that are propagated throughout the network. This also reduces the amount of processing overhead required to maintain the LSDB, making the network more scalable and efficient.
In conclusion, option D (Implement OSPF areas) is the correct answer to reduce the size of the LSDB in a network running single-area OSPF. Option C (Reduce the frequency of hello timers throughout the network) may also help reduce the LSDB size, but it is not as effective as implementing OSPF areas. Option A (Implement RIP as an overlay protocol on all devices) and option B (Add more devices to the OSPF network to help with LSDB processing) are not effective solutions to reducing the LSDB size.
