CSSLP Practice Test

MAC II 

Explanation: The various MAC levels are as follows: MAC I: It states that the systems have high availability and high integrity. MAC II: It states that the systems have high integrity and medium availability. MAC III: It states that the systems have basic integrity and availability. 

Hot Site

Explanation: A hot site is a duplicate of the original site of the organization, with full computer systems as well as near-complete backups of user data. It provides the backup facility, which is maintained in a constant order, with a full complement of servers, workstations, and communication links ready to assume the primary operations responsibility. A hot site is a backup site in case disaster has taken place in a data center. A hot site is located off site and provides the best protection. It is an exact replica of the current data center. In case a disaster struck to the data center, administrators just need to take the backup of recent data in hot site and the data center is back online in a very short time. It is very expensive to create and maintain the hot site. There are lots of third party companies that provide disaster recovery solutions by maintaining hot sites at their end. Answer: A is incorrect. A cold site is a backup site in case disaster has taken place in a data center. This is the least expensive disaster recovery solution, usually having only a single room with no equipment. All equipment is brought to the site after the disaster. It can be on site or off site. Answer: D is incorrect. Mobile sites are self-reliant, portable shells custom-fitted with definite telecommunications and IT equipment essential to meet system requirements. These are presented for lease through commercial vendors. Answer: C is incorrect. A warm site is, quite logically, a compromise between hot and cold sites. Warm sites will have hardware and connectivity already established, though on a smaller scale than the original production site or even a hot site. These sites will have backups on hand, but they may not be complete and may be between several days and a week old. An example would be backup tapes sent to the warm site by courier.

Custodian

Owner 

User  

Security auditor

Explanation: The following are the common roles with regard to data in an information classification program: Owner Custodian User Security auditor The following are the responsibilities of the owner with regard to data in an information classification program: Determining what level of classification the information requires. Reviewing the classification assignments at regular time intervals and making changes as the business needs change. Delegating the responsibility of the data protection duties to the custodian. The following are the responsibilities of the custodian with regard to data in an information classification program: Running regular backups and routinely testing the validity of the backup data Performing data restoration from the backups when necessary Controlling access, adding and removing privileges for individual users The users must comply with the requirements laid out in policies and procedures. They must also exercise due care. A security auditor examines an organization's security procedures and mechanisms.

Integration testing

Explanation: Integration testing is a software testing that seeks to verify the interfaces between components against a software design. Software components may be integrated in an iterative way or all together ("big bang"). Normally the former is considered a better practice since it allows interface issues to be localized more quickly and fixed. Integration testing works to expose defects in the interfaces and interaction between the integrated components (modules). Progressively larger groups of tested software components corresponding to elements of the architectural design are integrated and tested until the software works as a system. Answer: A is incorrect. Regression testing focuses on finding defects after a major code change has occurred. Specifically, it seeks to uncover software regressions, or old bugs that have come back. Such regressions occur whenever software functionality that was previously working correctly stops working as intended. Typically, regressions occur as an unintended consequence of program changes, when the newly developed part of the software collides with the previously existing code. Answer: D is incorrect. Unit testing refers to tests that verify the functionality of a specific section of code, usually at the function level. In an object-oriented environment, this is usually at the class level, and the minimal unit tests include the constructors and destructors. These types of tests are usually written by developers as they work on code (white-box style), to ensure that the specific function is working as expected. One function might have multiple tests, to catch corner cases or other branches in the code. Unit testing alone cannot verify the functionality of a piece of software, but rather is used to assure that the building blocks the software uses work independently of each other. Answer: C is incorrect. The black-box testing uses external descriptions of the software, including specifications, requirements, and design to derive test cases. These tests can be functional or non-functional, though usually functional. The test designer selects valid and invalid inputs and determines the correct output. There is no knowledge of the test object's internal structure. This method of test design is applicable to all levels of software testing: unit, integration, functional testing, system and acceptance. The higher the level, and hence the bigger and more complex the box, the more one is forced to use black box testing to simplify. While this method can uncover unimplemented parts of the specification, one cannot be sure that all existent paths are tested.

Qualitative risk analysis

Explanation: Qualitative risk analysis is the best answer as it is a fast and low-cost approach to analyze the risk impact and its effect. It can promote certain risks onto risk response planning. Qualitative Risk Analysis uses the likelihood and impact of the identified risks in a fast and cost-effective manner. Qualitative Risk Analysis establishes a basis for a focused quantitative analysis or Risk Response Plan by evaluating the precedence of risks with a concern to impact on the project's scope, cost, schedule, and quality objectives. The qualitative risk analysis is conducted at any point in a project life cycle. The primary goal of qualitative risk analysis is to determine proportion of effect and theoretical response. The inputs to the Qualitative Risk Analysis process are: Organizational process assets Project Scope Statement Risk Management Plan Risk Register Answer: B is incorrect. Historical information can be helpful in the qualitative risk analysis, but it is not the best answer for the question as historical information is not always available (consider new projects). Answer: D is incorrect. Quantitative risk analysis is in-depth and often requires a schedule and budget for the analysis. Answer: C is incorrect. Rolling wave planning is not a valid answer for risk analysis processes.
