The OIC FTP Adapter in theInvoke rolefacilitates interactions with an FTP server from an integration flow. Let’s break down each operation with exhaustive detail:

Option A: Write File

Supported:The FTP Adapter allows writing files to an FTP server. For example, you could use a Stage File action to prepare a CSV file and then invoke the FTP Adapter to write it to a remote directory like /inbound. This is a core capability for outbound file transfers.

Option B: Read File

Supported:Reading an entire file from an FTP server is possible in Invoke mode. You specify a file path (e.g., /outbound/data.csv), and the adapter retrieves itscontents, useful for processing complete files in one go, like a daily report.

Option C: Read File in Segments

Not Supported (Answer):This operation, which processes large files incrementally (e.g., 100 records at a time), is exclusive to theTrigger roleor Stage File actions, not the Invoke role of the FTP Adapter. In Invoke mode, the adapter doesn’t support segmented reading because it’s designed for direct, one-shot operations rather than iterative processing. For segmented reads, you’d use a File Adapter in Trigger mode or Stage File with a Connectivity Agent.

Option D: Delete File

Supported:Deleting a file on the FTP server (e.g., /archive/oldfile.txt) is a standard Invoke operation, often used for cleanup after processing.

Option E: Download File

Supported:Downloading retrieves a file to OIC for further processing, similar to Read File but typically implies storing it locally in the integration flow (e.g., staging it).

Why C is the Answer:The Invoke role focuses on discrete actions (write, read, delete, download), not iterative tasks like segmented reading, which requires a polling mechanism better suited to Trigger roles or Stage File actions.

Edge Case:If you need segmented reading from an FTP server, you’d download the file first using Invoke, then use a Stage File action to process it in segments— a workaround, not a direct capability.

Use Case Example:An integration writing a sales report to FTP (A), downloading a log file (E), and deleting an old backup (D) works fine, but attempting to read a 10GB file in segments (C) fails in Invoke mode.

Comprehensive and Detailed Explanation:

TheFor Eachaction in OIC iterates over a collection (e.g., multiple orders in a payload). Correct configuration involves:

Option C:Selecting theRepeating Elementfield and mapping it to the source element (e.g., /orders/order) containing the list of orders ensures OIC loops through each item individually. This is the standard and correct approach.

Option A:Parallel Processing exists but isn’t default for For Each; it’s an advanced setting requiring manual thread configuration, not ideal for basic iteration.

Option B:Group By is for aggregation, not individual processing, and doesn’t apply here.

Option D:Sequential Processing is implied in For Each, but “batch size” isn’t a configuration option for this action—it’s relevant to Stage File operations.

Mapping the repeating element ensures precise, individual order processing.

Comprehensive and Detailed Explanation:

Timeouts in synchronous flows:

Option A:Increasing timeouts might help but doesn’t address efficiency and risks longer delays.

Option B:Fine-grained calls in a loop could worsen performance, increasing latency.

Option C:Switching to an asynchronous flow decouples client waits from processing, using callbacks or notifications— a proven mitigation strategy.

C aligns with best practices for responsiveness.

Comprehensive and Detailed Explanation:

OIC’s unsaved changes feature safeguards design-time work against disruptions. Let’s explore each option in detail:

Option A: A user with the ServiceAdministrator role can recover the unsaved changes.

True:The ServiceAdministrator role has elevated privileges, including recovering unsaved changes from a crashed session. For example, if a developer’s browser crashes mid-flow, an admin can log in, access the integration, and restore the draft. This ensures continuity in team workflows.

Option B: A user with the ServiceAdministrator role can unlock an integration that has unsaved changes.

True:If an integration is locked due to a crash (e.g., user session terminates unexpectedly), a ServiceAdministrator can unlock it, allowing recovery or further editing. This is critical in scenarios where a developer leaves an integration in a locked state.

Option C: Changes made while editing a Connections page cannot be recovered.

True:OIC’s recovery mechanism doesn’t extend to the Connections page. Connection edits (e.g., updating credentials) are separate from integration flows and lack the same autosave granularity. If a crash occurs here, changes are lost, requiring re-entry.

Option D: Changes made while working inside a data mapper cannot be recovered.

False (Not True):Mapper changes (e.g., mapping fields between source and target)arerecoverable. OIC autosaves mapper edits as part of the integration draft. Forinstance, if you map “OrderID” to “PurchaseID” and the browser crashes, logging back in restores this work. This makes D the incorrect statement and the answer.

Option E: A backup copy is created after each complete task, therefore there is no time limit to logging back in and recovering the changes.

True:OIC creates backups after significant actions (e.g., adding an action, saving a map). There’s no strict time limit for recovery, as drafts persist until overwritten or discarded, offering flexibility post-crash.

Why D is the Answer:Mapper changes are integral to integration design and covered by OIC’s autosave, unlike Connection edits (C). D’s claim contradicts this capability.

Use Case Example:A developer mapping a complex payload in an ERP-to-CRM sync recovers their work after a network drop, proving mapper recovery works.
