Cisco 300-635 (DCNAUTO) Sample Questions:

01. An agent has run for a quarter with read-only tools against NDFC: telemetry queries, fault reads, and a pyATS learn snapshot. The team now wants it to be able to change the member list of one port channel on a single fabric, and is deciding what must be in place before that write tool is switched on.
Which two are required?
(Choose two.)
a) A service account scoped to that fabric and to the object types the write tool touches, issued separately from the read-only credential the agent has used since the pilot.
b) A broader read tool set, so the agent can confirm the effect of its own change without waiting for the next telemetry interval to deliver updated interface state.
c) A move from the controller's API to direct NETCONF sessions on the two switches carrying the port channel, so the change is applied at the devices that own the interfaces.
d) A tested rollback for the write tool, capturing the member list as it stood before the change, together with a verified path for restoring it on either switch.
e) A change of the port channel's telemetry subscription from SAMPLE to ON_CHANGE, so the agent observes the result of its own write as soon as interface state settles.
 
02. For six months an agent has been proposing NX-OS configuration diffs into a human approval queue. The metrics for the period read: 1,240 proposals, 1,240 approvals, median time from proposal to approval nine seconds.
What risk do these numbers indicate?
a) The approval step is adding latency to remediation, since nine seconds accumulates across a fabric-wide incident, so the pipeline's effective response time is worse than direct apply.
b) The approval gate has stopped functioning as a control, since reviewers are confirming rather than reading, so the pipeline's effective behavior is now unattended apply in all but name.
c) The agent's proposals are non-deterministic, since the same fabric condition can yield a differently worded diff, so the pipeline's effective output cannot be reproduced from the prompt.
d) The proposal rate is outrunning the reviewers, since the queue is being cleared for throughput, so the pipeline's effective constraint has moved to the controller's deploy step.
 
03. At 02:14 a configuration change appears on twelve leaf switches. The controller's log shows it was submitted through the API by the service account automation-svc, which is shared by the nightly CI pipeline, a scheduled compliance job, and an AI remediation agent. Asked who made the change and on what authority, the team cannot say.
What does this expose?
a) The log records the credential rather than the actor, so an agent-issued change cannot be told apart from a pipeline job; a distinct identity per actor is what makes the record reconstructable.
b) The change was submitted outside the approved maintenance window on a production fabric, so it bypassed the controller's change-control policy; enforcing that window is what makes the record reconstructable.
c) The log retention window is too short to cover an overnight change, so the entries needed to reconstruct what happened had already rolled over; extending log retention is what makes the record reconstructable.
d) The configuration archive keeps only the post-change state rather than a diff, so the content of the change is unknown; storing a pre-change snapshot is what makes the record reconstructable.
 
04. A remediation agent detects that a leaf switch is dropping traffic on an uplink and proposes a change to that port channel's member configuration. An engineer approves the proposal, the agent submits it through the fabric controller under its own service account, and the controller records the submission and then reports the deployment complete. The agent files the deployment result, marks the remediation successful, and closes the incident.
Half an hour later the same drops are still being reported on that uplink.
Which weakness in the agent's loop does this expose?
a) The submission carried the agent's own service account, so the controller's record cannot establish which actor issued the change or on whose authority it went ahead.
b) The loop finished on the controller's report of its own deployment, so nothing read the fabric afterward to compare it against the condition the remediation was raised for.
c) The approval was given on a proposal rather than on the configuration the controller would render from it, so the change was authorized before anyone could see what it would do.
d) The remediation was applied without a captured rollback point, so the member list the port channel carried beforehand cannot be restored on either switch.
 
05. While debugging a failing Jinja2 template, an engineer pastes a 200-line excerpt of a production leaf switch's running configuration into an externally hosted AI assistant. The excerpt carries the TACACS+ shared key, an SNMPv3 user, and the management addressing for the whole pod. The template is fixed within the hour, and the engineer deletes the conversation the same afternoon.
How should the team treat this event?
a) Treat the shared key and the SNMPv3 credentials as disclosed and rotate them, and record the addressing exposure, because the material left the trust boundary at the moment it was sent.
b) Treat the transport as the exposure and move future prompts to the enterprise endpoint over TLS, because the credentials were protected in flight and the real risk here is interception.
c) Treat the excerpt as low sensitivity because it is a configuration fragment rather than a full backup, and rely on the provider not surfacing one customer's content inside another customer's session.
d) Treat the exposure as closed now that the conversation is deleted, and remind the engineer to redact configuration before the next prompt, because the excerpt is no longer retrievable by anyone.
 
06. A team subscribes an externally hosted AI analytics service to the fabric's model-driven telemetry and forwards syslog to the same service. The exported sensor paths currently cover whole interface, BGP neighbor, and system subtrees, and the syslog stream carries hostnames, management addresses, and peer descriptions.
Which two actions best address the exposure this creates?
(Choose two.)
a) Narrow the exported sensor paths to the specific leaves the analysis actually consumes, rather than exporting whole interface and system subtrees to the provider.
b) Change the affected subscriptions from SAMPLE to ON_CHANGE, so that far fewer updates leave the fabric for the provider while the network sits in a steady state between events.
c) Classify the hostnames, addressing, and peer relationships as disclosed to the provider, and run the export through the same third-party data review as any outbound feed.
d) Terminate the export over TLS with mutual certificate authentication between each switch and the analytics collector, so that no third party can read the stream while it is in transit.
e) Raise the local collector's retention so that a full copy of everything exported also remains available inside the fabric's own trust boundary for later review.
 
07. A rendered uplink configuration was wrong in production. The engineer re-prompted the assistant, received a different template that renders correctly, and now proposes recording that prompt in the repository README as the way to reproduce the template.
Which assessment of that proposal is correct?
a) Regenerating the template from the stored prompt on each pipeline run keeps it current with whatever the assistant most recently knows about the platform's syntax and the collection in use, without anyone having to edit the repository.
b) Storing the prompt is adequate documentation once a reviewer has approved the rendered output, because the approval is what the audit trail actually records.
c) Recording the prompt alongside the identity and the version of the assistant makes the generation repeatable, provided that the same prompt is submitted through the same tool by whoever needs to produce the template again.
d) The same prompt need not return the same artifact, so the prompt does not reproduce the template; the reviewed and committed file, with a test that renders it, is what the team can rely on.
 
08. Before scripting their creation, an engineer at a university documents how the three NX-OS telemetry objects relate to each other.
Which two statements about that object model are correct?
(Choose two.)
a) Each subscription may reference exactly one destination group, so a second receiver requires a second subscription.
b) The destination group carries the paths to be collected, and the sensor group carries the receivers that will be sent the data.
c) One subscription may reference several sensor groups and several destination groups.
d) Nothing is streamed until a subscription references a sensor group and a destination group.
e) A sensor group starts collecting as soon as its paths are defined, and the subscription then selects which receivers get the data.
 
09. A source of truth records VLAN 240 on a rack's access ports. The leaf switches are carrying VLAN 340 on those same ports. Nobody can say which value is right: the record was edited last month by a planner, and a switch change was made by hand during an incident and never written back.
Which two practices would have kept one of the two authoritative?
(Choose two.)
a) Make the automation pipeline the only path that writes switch configuration, so an incident fix is expressed as a change to the record and applied from it.
b) Record the incident change in the source of truth as an exception entry, so the record documents both the intended VLAN and the value the switch is actually running.
c) Grant the on-call engineers direct CLI write access during incidents, on the condition that a ticket describing the change is filed within the same shift.
d) Remediate a detected difference by re-rendering and re-applying the record's intent, rather than editing the record to match what the switch is now running.
e) Store the rack's live interface and VLAN operational counters alongside the intended values, so a comparison can be made without reaching the switches.
 
10. A collection script logs in to a Nexus switch over SSH and needs the per-interface input-error counters. The current implementation runs show interface counters errors and applies a regular expression to the returned text. The team wants the retrieval step to survive a change in how that command lays out its display.
Which change to the retrieval step best meets that requirement?
a) Set terminal length 0 before issuing the command so the output arrives as one unpaginated block, and keep the existing regular expression.
b) Anchor the regular expression on the interface name at the start of each line instead of on fixed column offsets, so a wider column no longer shifts the match.
c) Run show interface counters errors | json and index the returned object by key, so the script depends on the names of the data rather than on its position in a table.
d) Increase the SSH read timeout and buffer the complete response before matching against it, and keep the existing regular expression.
