• Question 635:

  Which of the following UTP cables uses four pairs of twisted cable and provides transmission speeds of up to 16 Mbps?

  A. Category 5e B. Category 5
  C. Category 3
  D. Category 6
  C. Category 3

  ---

  Explanation/Reference:

  Category 3 type of UTP cable uses four pairs of twisted cable and provides transmission speeds of up to 16 Mbps. They are commonly used in Ethernet networks that operate at the speed of 10 Mbps. A higher speed is also possible by these cables implementing the Fast Ethernet (100Base-T4) specifications. This cable is used mainly for telephone systems. Answer option B is incorrect. This category of UTP cable is the most commonly used cable in present day networks. It consists of four twisted pairs and is used in those Ethernet networks that run at the speed of 100 Mbps. Category 5 cable can also provide a higher speed of up to 1000 Mbps. Answer option A is incorrect. It is also known as Category 5 Enhanced cable. Its specification is the same as category 5, but it has some enhanced features and is used in Ethernets that run at the speed of 1000 Mbps. Answer option D is incorrect. This category of UTP cable is designed to support high-speed networks that run at the speed of 1000 Mbps. It consists of four pairs of wire and uses all of them for data transmission. Category 6 provides more than twice the speed of Category 5e, but is also more expensive.

• Question 636:

  Which of the following is a communication protocol multicasts messages and information of all the member IP multicast group?

  A. IGMP
  B. ICMP
  C. BGP
  D. None
  E. EGP
  A. IGMP

• Question 637:

  Which of the following steps of the OPSEC process examines each aspect of the planned operation to identify OPSEC indicators that could reveal critical information and then compare those indicators with the adversary's intelligence collection capabilities identified in the previous action?

  A. Analysis of Threats
  B. Application of Appropriate OPSEC Measures
  C. Identification of Critical Information
  D. Analysis of Vulnerabilities
  E. Assessment of Risk
  D. Analysis of Vulnerabilities

  ---

  Explanation/Reference:

  OPSEC is a 5-step process that helps in developing protection mechanisms in order to safeguard sensitive information and preserve essential secrecy.

  The OPSEC process has five steps, which are as follows:

  1.Identification of Critical Information: This step includes identifying information vitally needed by an adversary, which focuses the remainder of the OPSEC process on protecting vital information, rather than attempting to protect all classified

  or sensitive unclassified information.

  2.Analysis of Threats: This step includes the research and analysis of intelligence, counter-intelligence, and open source information to identify likely adversaries to a planned operation. 3.Analysis of Vulnerabilities: It includes examining each

  aspect of the planned operation to identify OPSEC indicators that could reveal critical information and then comparing those indicators with the adversary's intelligence collection capabilities identified in the previous action.

  4.Assessment of Risk: Firstly, planners analyze the vulnerabilities identified in the previous action and identify possible OPSEC measures for each vulnerability. Secondly, specific OPSEC measures are selected for execution based upon a

  risk assessment done by the commander and staff.

  5.Application of Appropriate OPSEC Measures: The command implements the OPSEC measures selected in the assessment of risk action or, in the case of planned future operations and activities, includes the measures in specific OPSEC

  plans.

  E. the privileged EXEC
  C. user EXEC

• Question 639:

  Which of the following flags is set when a closed port responds to an Xmas tree scan?

  D. FIN
  A. RST

• Question 640:

  Which of the following interfaces uses hot plugging technique to replace computer components without the need to shut down the system?
