Answer:
FULL neighbor state.
(FULL/DR or FULL/BDR)
Explanation:
The fact that the routers are neighbors is not enough to guarantee an exchange of link status updates; they must form adjacencies to exchange link status updates. Adjacency is the next step after the process of establishing neighbors. Adjacent routers are routers that go beyond a simple Greeting exchange and act in the database exchange process. To reduce the amount of information exchange in a given segment, OSPF selects a router as a designated router (DR) and a router as a designated backup router (BDR) in each multiple access segment. The BDR is chosen as the backup mechanism in case the DR fails. The idea behind this is that routers have a central point of contact for the exchange of information. In order to verify if two routers have established an adjacency, you can use the command: show ip ospf neighbor.
Here is an example:
R1#show ip ospf neighbor

Answer:
To execute a prepared SQL statement, you can use the bindValue
Explanation:
In PHP, the bindValue () function is inbuilt and can be used to bind values and variables to a parameter, hence it is more versatile. In SQL, the bindValue () function ties value to question mark placeholder or corresponding named in order to adequately get the statement ready.
Answer:
Always back up your data. Prevention is the best protection.
Diversify your backups. You always want more than one backup system.
Encrypt sensitive data. Data is not always encrypted even when it's on a backup tape.
Address data security.
Use anti-virus and email security.
