Wireless users report frequent disconnections from the wireless network. While troubleshooting a network engineer finds that after the user a disconnect, the connection re-establishes automatically without any input required. The engineer also notices these message logs .

Which action reduces the user impact?
Correct Answer: D
Explanation
These message logs inform that the radio channel has
been reset (and the AP must be down briefly). With
dynamic channel assignment (DCA), the radios can
frequently switch from one channel to another but it also
makes disruption. The default DCA interval is 10 minutes,
which is matched with the time of the message logs. By
increasing the DCA interval, we can reduce the number of
times our users are disconnected for changing radio
channels.
One of the best practices to secure REST APIs is using password hash. Passwords must always be hashed to protect the system (or minimize the damage) even if it is compromised in some hacking attempts. There are many such hashing algorithms which can prove really effective for password security e.g. PBKDF2, bcrypt and scrypt algorithms.
Other ways to secure REST APIs are: Always use HTTPS, Never expose information on URLs (Usernames, passwords, session tokens, and API keys should not appear in the URL), Adding Timestamp in Request, Using OAuth, Input Parameter Validation.
