Questions # 16:

A weak point in an organization’s defenses is a:

Options:

Anti-virus software

Security model problem

Penetration

Vulnerability

Firewall

Answer

Explanation

A weak point in an organization’s defenses is referred to as a vulnerability, which is a flaw that could be exploited. The DAMA-DMBOK defines a vulnerability as “a weakness in a system, application, or process that can be exploited by a threat, leading to potential security breaches” (DMBOK2, Chapter 8: Data Security, p. 295).

Options A and E are security tools, B is vague, and C refers to an exploit, not the weak point itself.

Questions # 23:

A database that is growing at 100% per annum compound will be:

Options:

4 times its original size at the end of year 2

6 times its original size at the end of year 3

2 times its original size at the end of year 5

3 times its original size at the end of year 2

Half its original size at the end of year 2

Answer

Explanation

A database growing at 100% per annum compound doubles in size each year, following the formula for compound growth: Size = Initial Size × (1 + Growth Rate)^Years. For a 100% growth rate (1.0), after 2 years: Size = Initial Size × (1 + 1)^2 = Initial Size × 2^2 = 4 times the original size. The DAMA-DMBOK discusses capacity planning, noting that “data growth projections, including compound growth, are critical for planning storage and performance requirements” (DMBOK2, Chapter 10: Data Storage and Operations, p. 391).

Calculating for other options: After 3 years, the size is 2^3 = 8 times (not 6, so B is incorrect); after 5 years, it’s 2^5 = 32 times (not 2, so C is incorrect); after 2 years, it’s not 3 times (D) or half (E). Thus, A is correct.
