Explanation
Static application security testing (SAST) is conducted against offline systems with previous knowledge of them, including their source code. Live testing is not part of static testing but rather is associated with dynamic testing. Production system scanning is not appropriate because static testing is done against offline systems.
Injection attempts are done with many different types of testing and are not unique to one particular type. It is therefore not the best answer to the question.

Data loss prevention (DLP) solutions allow for control of data outside of the application or original system.
They can enforce granular control such as printing, copying, and being read by others, as well as forcing expiration of access. Intrusion detection system (IDS) and intrusion prevention system (IPS) solutions are used for detecting and blocking suspicious and malicious traffic, respectively, whereas a web application firewall (WAF) is used for enforcing security or other controls on web- based applications.

Shares are used within a cloud environment to prioritize resource allocation when customer requests exceed the available resources. Cloud providers utilize shares by assigning a priority score to each customer and allocating resources to those with the highest scores first. Scoring is a component of shares that determines the actual order in which to allocate resources. Neither weighting nor prioritization is the correct term in this case.

Explanation
DNSSEC relates to the integrity of DNS resolutions and the prevention of spoofing or redirection, and does not pertain to the actual security of transmissions or the protection of data.

Explanation
BIOS is the firmware that governs the physical initiation and boot up of a piece of hardware. If it is compromised, an attacker could have access to hosted systems and make configurations changes to expose or disable some security elements on the system.
