Question 68
Which statement about an RSPAN session configuration is true?
Correct Answer: C
Explanation The traffic for each RSPAN session is carried over a user-specified RSPAN VLAN that is dedicated for thatRSPAN session in all participating switches -> This VLAN can be considered a special VLAN type -> Answer'A special VLAN type must be used as the RSPAN destination' is correct.

Question 69
The login method is configured on the VTY lines of a router with these parameters. * The first method for authentication is TACACS * If TACACS is unavailable, login is allowed without any provided credentials Which configuration accomplishes this task?
Correct Answer: C
Explanation According to the requirements (first use TACACS+, then allow login with no authentication), we have to use "aaa authentication login ... group tacacs+ none" for AAA command. The next thing to check is the if the "aaa authentication login default" or "aaa authentication login list-name" is used. The 'default' keyword means we want to apply for all login connections (such as tty, vty, console and aux). If we use this keyword, we don't need to configure anything else under tty, vty and aux lines. If we don't use this keyword then we have to specify which line(s) we want to apply the authentication feature. From above information, we can find out answer 'R1#sh run | include aaa aaa new-model aaa authentication login default group tacacs+ none aaa session-id common R1#sh run | section vty line vty 0 4 password 7 0202039485748 If you want to learn more about AAA configuration, please read our AAA TACACS+ and RADIUS Tutorial - Part 2. For your information, answer 'R1#sh run | include aaa aaa new-model aaa authentication login telnet group tacacs+ none aaa session-id common R1#sh run | section vty line vty 0 4 R1#sh run | include username R1#' would be correct if we add the following command under vty line ("line vty 0 4"): "login authentication telnet" ("telnet" is the name of the AAA list above)
Question 70
what is a benefit of using a Type 2 hypervisor instead of a Type 1 hypervisor?
Correct Answer: D
Explanation There are two types of hypervisors: type 1 and type 2 hypervisor. In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical server. Then instances of an operating system (OS) are installed on the hypervisor. Type 1 hypervisor has direct access to the hardware resources. Therefore they are more efficient than hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM Server, KVM and Microsoft Hyper-V. In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an operating system and not the physical hardware directly. A big advantage of Type 2 hypervisors is that management console software is not required. Examples of type 2 hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft Virtual PC (only runs on Windows). Type 1 is more efficient and well performing, it is also more secure than type 2 because the flaws and vulnerabilities that are endemic to Operating Systems are often absent from Type 1, bare metal hypervisors. Type 1 has better performance, scalability and stability but supported by limited hardware.
