RADIUS server, SCP and swipe card questions.

 4.You are onsite as a consultant. The client’s many remote-access users experience connection problems. Basically, when users try to connect, the system cannot service their authentication requests. What kind of server might you recommend to alleviate this problem?
 A. RADIUS server
 B. IPsec server
 C. Proxy server
 D. Kerberos server
5. Which of the following services or protocols use SSH technology to provide additional security to communications? (Choose two.)
6. Which of the following systems use a credit card-sized plastic card read by a reader on the outside of the door?
 A. Contiguity reader
 B. Key fob
 C. Swipe card
 D. Cipher lock

4. A. By installing a RADIUS server, you can move the workload associated with authentication to a dedicated server. A proxy server would not improve the dial-up connection’s performance. There is no such thing as a specific Kerberos server or an IPsec server.
5. A, B. Secure Shell (SSH) technology is used by both Secure Copy Protocol (SCP) and Secure File Transfer Protocol (SFTP). Answers C and D are incorrect because Simple Network Management Protocol (SNMP) and Simple Mail Transfer Protocol (SMTP) do not use SSH technology for additional security.
6. C. Swipe card systems use a credit-card-sized plastic card read by a reader on the outside of the door. To enter the server room, you must swipe the card (run it through the reader), at which point it is read by the reader, which validates it.
