Chapter $5$ Availability $[10]$

$1$ How is availability related to the concept of reliability?

Availability encompasses reliability by adding the notion of recovery

Availability and reliability are unrelated concepts

Reliability is a subset of availability

Availability is a subset of reliability

$2$ What is the definition of availability as an aspect of dependability?

The ability to avoid failures

The ability to mask or repair faults within a specified time interval

The ability to recover from any failure instantly

The ability to achieve high performance levels consistently

$3$ How is availability related to security and performance?

Availability is unrelated to security and performance

Denial$-$of$-$service attacks are aimed at reducing availability

Security and performance are subsets of availability

Security and performance are unrelated to availability

$4$ What is the fundamental goal of availability in software systems?

To minimize service outage time by mitigating faults

To eliminate all potential failures completely

To achieve the highest possible performance levels

To ensure complete security against all types of attacks

$5$ What does availability refer to in the context of a software system?

The ability of the system to be fault$-$free

The ability of the system to be always operational

The ability of the system to recover from all faults instantly

The ability of the system to prevent any failures from occurring

Chapter $6.$ Interoperability $[10]$

$1$ What does interoperability encompass beyond just exchanging data?

The ability to interpret exchanged data correctly

The ability to exchange data at high speed

The ability to secure exchanged data

The ability to store exchanged data efficiently

$2$ Why is context important when discussing interoperability?

Because it determines the systems with which interoperability is required

Because it defines the level of complexity in the data exchange process

Because it influences the discovery and handling of service responses

Because it ensures the availability of interfaces for system integration

$3$ What are the two critical concepts clarified in the discussion of interoperability?

The importance of data exchange protocols and encryption methods

The significance of system behavior expectations and interface assumptions

The role of syntactic and semantic compatibility in system integration

The necessity of API documentation and programming standards

$4$ In what ways can systems exchange information, according to the text?

Through direct communication only

Through indirect communication methods

Through predefined API calls exclusively

Through runtime execution of shared code

$5$ Which of the following best describes interoperability in software architecture?

The ability of a system to run on different hardware platforms.

The ability of a system to be easily modified and extended.

The ability of a system to exchange data and work seamlessly with other systems, regardless of their origin.

The ability of a system to use different programming languages internally.

$6$ Standardized APIs $($Application Programming Interfaces$)$ are crucial for interoperability because they:

Define the specific functionalities a system offers.

Guarantee the efficiency of data exchange between systems.

Enforce security measures for communication between systems.

All of the above.

$7$ Which of the following design principles promotes interoperability?

Tight coupling, where components are highly dependent on each other.

Openness, where systems readily share data and functionalities through well$-$defined interfaces.

Legacy code retention, relying on existing code without updates for compatibility.

Vendor lock$-$in$,$ using proprietary technologies that limit integration with other systems.

$8$ Choosing established and widely adopted data formats for interoperability:

Increases complexity due to the need for additional conversion processes.

Reduces development time and simplifies integration with other systems.

Limits the flexibility for using custom data structures within the system.

Provides no benefit towards interoperability.

$9$ What is a potential drawback of prioritizing interoperability in software architecture?

Reduced security, as data exchange might require access to broader system functionalities.

Increased development complexity due to the need for compliance with various standards.

Decreased system performance, as communication and data formatting overhead can add delays.

All of the above.

$10$ When designing a software architecture for future integration possibilities, focusing on interoperability involves:

Using the latest and most advanced technologies, regardless of industry standards.

Adopting well$-$documented and open standards for communication and data formats.

Limiting the number of external dependencies and integrations to minimize complexity.

Prioritizing development speed and cost$-$effectiveness over long$-$term interoperability.
