You want to ensure that a single-area OSPF network will be loop free.
In this scenario, what are two requirements that satisfy this requirement? (Choose two.)
You want to ensure that a single-area OSPF network will be loop free.
In this scenario, what are two requirements that satisfy this requirement? (Choose two.)
To ensure that a single-area OSPF network will be loop-free, two crucial requirements must be met. First, the Shortest Path First (SPF) algorithm must prune looped paths. This is fundamental to OSPF, as SPF calculates the shortest path tree from every node, ensuring that data packets always take the most efficient, loop-free route. Second, all nodes within an area must have the same information in their Link State Databases (LSDBs). This uniformity ensures that every router within the area has a synchronized view of the network topology, which is essential for consistent routing decisions and loop prevention.
DR/BDR doesnt ensure information sharing within the domain
The statement about the DR/BDR (Designated Router/Backup Designated Router) ensuring that each node within an area has the same information in their LSDBs is incorrect. While DR/BDR election helps reduce OSPF control traffic by limiting LSDB synchronization to only the DR and BDR, it does not ensure that each node within an area has the same LSDB information. OSPF routers exchange LSAs (Link State Advertisements) to build and maintain their LSDBs, and all routers within the same area should eventually have identical LSDBs regardless of the DR/BDR election.
A is wrong!
BR/DR only deals with shared segments to reduce LSA flooding and is not about controlling loops.
