Two teams at Larkspur Health maintain similarly sized modules of the patient portal. Team A has a documented policy for what design documentation is required, how it’s disseminated, and how much time developers get to write it. Team B has none of that, though both teams’ developers are equally skilled. A year later, Team B’s maintenance work is taking noticeably longer per change. What best explains the gap?

You will need to read this paragraph for any question about the twins with anorexia. There are up to 3 questions using this paragraph. Researchers investigated the extent to which 30 pairs of identical and fraternal female twins shared with their twin a diagnosis for the eating disorder anorexia nervosa. Identical twins are genetically identical, and share the same DNA pattern. Fraternal twins are only as genetically similar as any sibling pair. Researchers found that 9 out of 16 pairs of the identical twins were diagnosed with anorexia nervosa, while 1 out of 14 pairs of the fraternal twins were diagnosed with anorexia nervosa.

Be sure to read the paragraph about twins with anorexia to answer this question. Which of the following conclusions can be made based on the data collected in this study?

Which statement is true about current demographic trends in the United States?

Vantage Grid adds redundant backup generators to a substation specifically to satisfy a resilience requirement about surviving a power-source failure. During a later review, an engineer notices the redundancy has also improved the substation’s overall availability and reliability numbers, well beyond what the resilience requirement alone called for. Larkspur Health’s engineers separately observed something similar: breaking a monolithic patient-portal module into smaller, independent modules — done to make future changes easier to verify in isolation — also happened to make the system easier to adapt to a new computing platform later. What single idea explains both observations?

Larkspur Health’s leadership wants to formally assess how mature its software maintenance function is and identify concrete steps to improve it over time — not just patch individual complaints as they come in. A consultant recommends borrowing the structure of a well-known process-maturity framework, but adapted specifically to maintenance activities rather than general development. What is she likely recommending?

Larkspur Health is based entirely in the United States, but its patient portal has started attracting a small number of users living in the European Union. Leadership assumes that because the company has no EU offices and doesn’t market there, none of the European Union’s General Data Protection Regulation (GDPR) applies to them. Is that assumption correct, and what would Larkspur still need to handle if it isn’t?

Larkspur Health’s privacy page states, in reassuring language, that patient data “is kept safe and secure,” but an internal audit finds no actual encryption at rest, no access logging, and no incident-response plan behind that statement. Which principle does this gap most directly violate, and why does the wording of the policy itself not satisfy it?

Vantage Grid’s requirements engineers are kicking off a resilience-requirements effort for a new substation-control system. Before they can decide what the system should do about any specific threat, they need to know what’s actually worth protecting in the first place. Which of the following belongs at the very start of that process?

Vantage Grid’s team has identified that a cyberattack could disrupt real-time monitoring of a substation. Before writing the actual resilience requirement, they need to define specific limits: how much monitoring degradation is tolerable, how long a total loss of monitoring can last, and how quickly the system must detect and recover from the disruption. Given that Vantage Grid, like most organizations, doesn’t have unlimited engineering resources, what should immediately follow once those limits are defined?
