You have just configured a DNS server. Your security team mandates that you cannot use the root hint servers for external lookups. Instead, all external lookups must go through the OpenDNS servers 208.67.220.220 and 208.67.222.222. What mechanism in the DNS server setup lets you specify a specific DNS server to query for external lookups ?

Ann is a CSULA student trying to access (https://www.calstatela.edu) from the campus library. Her request must use Domain Name System (DNS) resolution to translate the name (https://www.calstatela.edu) to an IP address. Assume that CSULA DNS name resolution uses iterated queries and her request first goes to the CSULA local DNS server shown in the figure. In the following picture: 1. Fill in the blanks to show all the servers in the DNS hierarchy this request must be sent to, starting from and including the root DNS server. 2. Draw arrows with sequence numbers showing the steps in the DNS resolution. The first and the last step in DNS resolution are shown in the figure.

Which of the following gives the best explanation of the differences between RADIUS and TACACS+? TACACS+ employs the UDP protocol, whereas RADIUS uses the TCP protocol. RADIUS is supported by the Cisco Secure ACS software, although TACACS+ is not supported. TACACS+ just encrypts the password, while RADIUS encrypts all of the communication that takes place. In contrast to TACACS+, which keeps authentication and authorization distinct procedures, RADIUS combines both processes into a single flow.
