Question 1	What is the speed of the IDS-4250 sensor? A. 80Mbps B. 250Mbps C. 300Mbps D. 500Mbps
A1:	Answer D is correct. The IDS-4250 without the IDS Accelerator card installed operates at 500Mbps. Answer A is the speed of the IDS-4215. Answer B is the speed of the IDS-4235, and Answer C is none of the sensors. Therefore, Answers A, B, and C are incorrect.
Question 2	How many service accounts can an IDS version 4.0 sensor support at one time? A. None B. One C. Two D. Three
A2:	Answer B is correct. The IDS version 4.0 software supports only a single service account at a time. You should only create and use the service account with the help of Cisco Technical Assistance Center (TAC) technical support. Therefore, Answers A, C, and D are incorrect.
Question 3	What interfaces on an IDS-4250-XL are used for sensing? (Choose all that apply.) A. int0 B. int1 C. int2 D. int3
A3:	Answers C and D are correct. When you install the XL card into an IDS-4250 (thus making the sensor an IDS-4250-XL), the normal int0 sniffing port is converted to a TCP reset only port. Thus, only int2 and int3 are the available sniffing ports for the sensor. Answer A is incorrect because it is the TCP reset interface on the XL sensor. Answer B is incorrect because it is the command and control interface. Therefore, Answers A and B are incorrect.
Question 4	What routers support the NM-CIDS? (Choose all that apply.) A. 1600 B. 2600 C. 2700 D. 3600 E. 3700 F. 5000
A4:	Answers B, D, and E are correct. The NM-CIDS module is supported only on the 2600, 3600, and the 3700 model routers. Therefore, Answers A, C, and F are incorrect.
Question 5	What must you do to an IDS-4220 before you upgrade the IDS software from version 3.0 to 4.0? A. Upgrade the BIOS. B. Swap the console port and the sensor port. C. Install a second hard drive. D. Upgrade the memory.
A5:	Answer D is correct. The 4210 and 4220 both only have 256MB of RAM and you should increase the memory to 512MB before you upgrade to 4.0. Answer A is incorrect because the BIOS upgrades are more commonly done on 4235 and 4250 models, which don't have BIOS version A04, and not on the 4220. Answer B is incorrect because you do not swap the console port with the sensor port; you actually swap the command and control port with the sensor port. Answer C is incorrect because you do not need to install a second hard drive (the upgrade comes on a CD). Therefore, Answers A, B, and C are incorrect.
Question 6	What command should you use to configure your sensor for the first time? A. init sensor B. reset C. setup D. set default
A6:	Answer C is correct. You use the setup command to configure the hostname, IP address, netmask , default gateway, Telnet server, and Web server port. Answer A is incorrect because the init sensor command does not exist. Answer B is incorrect because you use the reset command to shut down the router. Answer D is incorrect because the set default command does not exist.
Question 7	What must you do to a 4230 model sensor before upgrading to IDS software 4.0? A. Upgrade the BIOS. B. Swap the command and control port and the sensor port. C. Install a second hard drive. D. Upgrade the memory.
A7:	Answer B is correct. The IDS 4.0 software changes the interfaces used by the 4220 and 4230 models for monitoring and command and control. Before you upgrade your sensor, therefore, you must swap the cables connecting these interfaces. Answer A is incorrect because the BIOS upgrades are more commonly done on 4235 and 4250 models, which don't have BIOS version A04, and not on the 4230. Answer C is incorrect because you do not need to install a second hard drive (the upgrade comes on a CD). Answer D is also incorrect because the 4230 should already have enough RAM.
Question 8	On the IDS-4250, which PCI slot is the IDS Accelerator XL card supported on? A. Lower slot only B. Upper slot only C. Either upper or lower slot D. Not supported
A8:	Answer B is correct. The XL card is only supported on the upper PCI slot. Therefore, Answers A, C, and D are incorrect.
Question 9	Which interface is used for command and control on the IDS-4215 model? A. int0 B. int1 C. int0 or int1 D. Console port
A9:	Answer B is correct. The command and control is only supported on int1. Answer A is incorrect because int0 is used for sensing, not command and control. Answer C is incorrect because only int1 can be used for command and control. Answer D is incorrect because the console port is only used for configuring the serial terminal.
Question 10	What is the first thing you are required to perform after you upgrade your IDS software and reboot? A. You must run the init sensor command. B. You must run the setup command. C. You must create a service account. D. You must change your password.
A10:	Answer D is correct. After you reboot or first turn on your sensor after an upgrade, you are required to change the administrator password. Answer A is incorrect because there is no such command. Answer B is incorrect because you must first change your password, and then you can optionally execute the setup command. Answer C is incorrect because the service account is not required to run the sensor.
Question 11	What is the default administrator name and password? A. cisco, attack B. cisco, netranger C. cisco, CISCO D. cisco, cisco
A11:	Answer D is correct. The default username and password combination is cisco and cisco ; you must change this password on the first login. Answers A, B, and C are incorrect.
