CA Technology & Tools 3 — Questions and Answers
Question 1: An institution is implementing web archiving. Which tool developed by the Internet Archive is commonly used by archives for crawling and preserving websites?
- Heritrix (Correct answer)
- Wayback Machine API
- HTTrack
- wget
Correct answer: Heritrix
Heritrix is the Internet Archive's open-source web crawler specifically designed for archival-quality web harvesting.
Question 2: PDF/A is a version of PDF designed specifically for which purpose?
- Interactive multimedia presentations
- Long-term archival preservation of electronic documents (Correct answer)
- High-speed web delivery of documents
- Encrypted transmission of sensitive records
Correct answer: Long-term archival preservation of electronic documents
PDF/A is an ISO-standardized version of PDF that prohibits features unsuitable for long-term archiving, such as font linking and encryption.
Question 3: Which international standard defines the Open Archival Information System (OAIS) reference model?
- ISO 15489
- ISO 14721 (Correct answer)
- ISO 27001
- ISO 9001
Correct answer: ISO 14721
ISO 14721 formally defines the OAIS reference model, providing a conceptual framework for digital preservation systems.
Question 4: When an archive migrates digital records from one format to another to counter obsolescence, this preservation strategy is known as:
- Emulation
- Normalization
- Format migration (Correct answer)
- Replication
Correct answer: Format migration
Format migration involves converting digital objects from one file format to another to ensure continued accessibility as technologies evolve.
Question 5: Which of the following tools is most commonly used by archives to create and manage EAD-encoded finding aids?
- ArchivesSpace (Correct answer)
- CONTENTdm
- PastPerfect
- Omeka
Correct answer: ArchivesSpace
ArchivesSpace is the leading open-source archival management system that supports EAD export and is widely adopted by academic and institutional archives.
Question 6: A digitization project specification calls for scanning documents at 400 PPI. What does PPI measure in this context?
- Pixels per image
- Pixels per inch—the spatial resolution of the scanned image (Correct answer)
- Pages processed per iteration
- Percentage of pixels identified as text
Correct answer: Pixels per inch—the spatial resolution of the scanned image
PPI (pixels per inch) measures the spatial resolution of a digital image, indicating how much detail is captured per unit of physical length.
Question 7: Which preservation strategy involves creating an environment that mimics obsolete software or hardware so original digital objects can still be rendered?
- Format migration
- Replication
- Emulation (Correct answer)
- Normalization
Correct answer: Emulation
Emulation recreates the behavior of obsolete hardware or software environments, allowing original digital objects to run without format conversion.
