You work as the Network Administrator for McNeil Inc. The company has a Unix-based network. You want to identify the secure terminals from where the root can be allowed to log in. Which of the following Unix configuration files can you use to accomplish the task?
In Unix, the /etc/securetty file is used to identify the secure terminals from where the root can be allowed to log in.
Answer B is incorrect. In Unix, the /etc/ioports file shows which I/O ports are in use at the moment.
Answer A is incorrect. In Unix, the /etc/services file is the configuration file that lists the network services that the system supports.
Answer C is incorrect. In Unix, the /proc/interrupts file is the configuration file that shows the interrupts in use and how many of each
there has been.
A Cisco router can have multiple connections to networks. These connections are known as interfaces for Cisco Routers. For naming each interface, Cisco generally uses the type of interface as part of the name. Which of the following are true about the naming conventions of Cisco Router interfaces?
Each correct answer represents a complete solution. Choose all that apply.
A Cisco router can have multiple connections to networks. These connections are known as interfaces for Cisco Routers. For naming each interface, Cisco generally uses the type of interface as part of the name.
Following are some of the naming conventions of Cisco Router interfaces:
An Ethernet interface that is fast always starts with an F.
An interface connected to a serial connection always starts with an S.
An interface connected to an Ethernet segment of the network always starts with an E.
An interface connected to a Token Ring segment always starts with To.
The following output is generated by running the show ip route command:
RouterA#show ip route
< - - Output Omitted for brevity - ->
Which next hop address will RouterA use in forwarding traffic to 10.10.100.0/24?
The routing table displays various RIP and Connected routes. There is no routing entry for 10.10.100.0/24, but there is a default route in the
routing table using 172.18.1.1 as the next hop router. Given that 10.10.100.0/24 does not have a direct entry in the routing table, RouterA
will forward traffic to the default route next hop address of 172.18.1.1.
Answer A is incorrect. The address does not appear in the routing table as a next hop router, in addition to being an actual subnet
number for 192.168.10.0/24.
Answer C is incorrect. 172.18.50.1 is the next hop for reaching 192.168.11.0.
Answer B is incorrect. 172.18.60.1 is the next hop for reaching 192.168.12.0.

You work as a Network Administrator for Tech Perfect Inc. For security issues, the company requires you to harden its routers. You therefore
write the following code:
Router#config terminal
Router(config) #no ip bootp server
Router(config) #no ip name-server
Router(config) #no ntp server
Router(config) #no snmp server
Router(config) #no ip http server
Router(config) #^Z
Router#
What services will be disabled by using this configuration fragment?
Each correct answer represents a complete solution. Choose all that apply.
The above configuration fragment will disable the following services from the router:
The BootP service
The DNS function
The Network Time Protocol
The Simple Network Management Protocol
Hyper Text Transfer Protocol
