Matt, the Chief Information Security Officer (CISO), tells the network administrator that a security company has been hired to perform a penetration test against his network. The security company asks Matt which type of testing would be most beneficial for him. Which of the following BEST describes what the security company might do during a black box test?
A. The security company is provided with all network ranges, security devices in place, and logical maps of the network. B. The security company is provided with no information about the corporate network or physical locations. C. The security company is provided with limited information on the network, including all network diagrams. D. The security company is provided with limited information on the network, including some subnet ranges and logical network diagrams.
Answer: B
Explanation: The term black box testing is generally associated with application testing. However, in this question the term is used for network testing. Black box testing means testing something when you have no knowledge of the inner workings.
Black-box testing is a method of software testing that examines the functionality of an application without peering into its internal structures or workings. This method of test can be applied to virtually every level of software testing: unit, integration, system and acceptance. It typically comprises most if not all higher level testing, but can also dominate unit testing as well. Specific knowledge of the application’s code/internal structure and programming knowledge in general is not required. The tester is aware of what the software is supposed to do but is not aware of how it does it. For instance, the tester is aware that a particular input returns a certain, invariable output but is not aware of how the software produces the output in the first place.
A network engineer is conducting an assessment for a customer that wants to implement an 802.11n wireless network. Before the engineer can estimate the number of WAPs needed, it is important to reference which of the following?

The RAID controller on a server failed and was replaced with a different brand. Which of the following will be needed after the server has been rebuilt and joined to the domain?
A. Vendor documentation B. Recent backups C. Physical IP address D. Physical network diagram
Correct Answer: B
Explanation: If the RAID controller fails and is replaced with a RAID controller with a different brand the RAID will break. We would have to rebuild a new RAID disk, access and restore the most recent backup to the new RAID disk. Note: RAID controller is a hardware device or software program used to manage hard disk drives (HDDs) or solid-state drives (SSDs) in a computer or storage array so they work as a logical unit. In hardware-based RAID, a physical controller is used to manage the RAID array.
While monitoring the network, a technician notices that the network traffic to one of the servers is extremely high. Which of the following should the technician use to verify if this is a concern?

A users computer will not boot. A technician notices four indicator lights on the backside of the computer. Two of the lights are green, and two are amber. Which of the following documentation should the technician read to determine what the lights are indicating?
A. Network diagram B. Computer manual C. Asset management D. Wiring scheme
Correct Answer: B
Explanation: The best resource for troubleshooting computer problems is the manual that came along with it. Similar to any electronic device, the manual lists common problems and their solutions.
