The answer is that Junos configuration archival uses FTP or SCP to transfer files. This is correct because the `system archival` hierarchy in Junos is specifically designed to automate the backup of committed configurations, allowing administrators to schedule periodic transfers to a remote server via FTP or SCP, preserving configuration history without manual intervention. On the JNCIA-Junos exam, this topic tests your understanding of operational automation within the system hierarchy, often appearing as a multiple-choice question where the trap is assuming archival only supports local storage or TFTP. A common memory tip is to remember that archival is for remote, secure copies—think “FTP or SCP, not TFTP or local”—and that the `system` hierarchy controls this feature, not `interfaces` or `protocols`.
JNCIA-JUNOS Junos Configuration Basics Practice Question
This JNCIA-JUNOS practice question tests your understanding of junos configuration basics. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which TWO statements about configuration archival in Junos are true?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The 'system archival' hierarchy enables automatic backup of configurations.
Option B is correct because the 'system archival' hierarchy in Junos is specifically designed to enable automatic backup of configuration files. This feature allows administrators to configure periodic transfers of committed configurations to a remote server, ensuring configuration history is preserved without manual intervention.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

For each option: why learners choose it and why it is or isn't the right answer here.
✗
Archival stores the candidate configuration.
Why it's wrong here
Archival stores the committed (active) configuration, not the candidate.
✓
The 'system archival' hierarchy enables automatic backup of configurations.
Why this is correct
This configuration block defines archival settings.

✗
Archival only saves the rescue configuration.
Why it's wrong here
Archival saves the active configuration, not specifically the rescue config.
✓
Archival can use FTP or SCP to transfer files.
Why this is correct
Supported transfer protocols include FTP, SCP, and others.
Related concept
Read the scenario before looking for a memorised answer.
✗
Archival automatically archives after every commit without any configuration.
Why it's wrong here
Archival must be explicitly configured; it is not automatic.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse the candidate configuration with the committed configuration, assuming archival saves the uncommitted changes, when in fact it only archives the active committed configuration after a successful commit.
Detailed technical explanation
How to think about this question
Under the hood, Junos archival uses a transfer-on-commit model where the system copies the active configuration file (typically /config/juniper.conf.gz) to a remote server via FTP, SCP, or HTTP. The archival process can be triggered by a commit operation or scheduled at regular intervals, and it supports transfer-format options like 'gzip' or 'tar' to compress the configuration. In real-world scenarios, this is critical for compliance and rollback planning, as it provides a versioned history of configuration changes outside the local device.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the JNCIA-JUNOS exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
