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
You work as a Software Developer for UcTech Inc. You want to create a new session. Which of the following methods can you use to accomplish the task?
Each correct answer represents a complete solution. Choose all that apply.
The getSession() method of the HttpServletRequest interface returns the current session associated with the request, or creates a new
session if no session exists. The method has two syntaxes as follows:
public HttpSession getSession(): This method creates a new session if it does not exist.
public HttpSession getSession(boolean create): This method becomes similar to the above method if create is true, and returns the
current session if create is false. It returns null if no session exists.
Answer B is incorrect. The getSession(false) method returns a pre-existing session. It returns null if the
client has no session
associated with it.
Answer A and E are incorrect. There is no such method as getNewSession() in Java.
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?

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.
Which TCP and UDP ports can be used to start a NULL session attack in NT and 2000 operating systems?
A null session is an anonymous connection to a freely accessible network share called IPC$ on Windows-based servers. It allows immediate
read and write access with Windows NT/2000 and read-access with Windows XP and 2003.
The command to be inserted at the DOS-prompt is as follows:
net use \\IP address_or_host name\ipc$ '' '/user:'
net use
Port numbers 139 TCP and 445 UDP can be used to start a NULL session attack.
