Question 760
A team emails raw switch configurations containing management credentials to external contractors. What safeguard is missing?
- Retain protected history with version tags
- Encrypt and control access to backups
- Verify backup integrity and readability
- Export known-good configuration off-device
Explanation
Correct Answer
B:Restrict and protect configuration archives by authorized access and encryption. Configuration archives can contain management addresses and sensitive service settings.
Incorrect Answers
A:A backup policy should preserve multiple approved versions, timestamps and device identities. But this does not address the case requirement to avoid exposing sensitive configuration data.
C:Archived files must be complete, accessible, correct version and free of transfer corruption. But this does not address the case requirement to avoid exposing sensitive configuration data.
D:A remote backup survives device loss better than only an on-switch checkpoint. But this does not address the case requirement to avoid exposing sensitive configuration data.
Question 761
A replacement switch rejects several restored commands because its hardware is incompatible. What practice should have caught this?
- Include dependencies and device inventory
- Practice restoration on compatible hardware
- Verify backup integrity and readability
- Encrypt and control access to backups
Explanation
Correct Answer
B:Test restoration against supported target hardware and software. Restore testing confirms syntax and platform compatibility rather than assuming a backup is usable.
Incorrect Answers
A:Recovery plans should record optics, license, image, model and downstream mapping, not only text configuration. But this does not address the case requirement to prove restore compatibility.
C:Archived files must be complete, accessible, correct version and free of transfer corruption. But this does not address the case requirement to prove restore compatibility.
D:Configuration archives can contain management addresses and sensitive service settings. But this does not address the case requirement to prove restore compatibility.
Question 762
A failed chassis is replaced but technicians lack port patch maps and required optics. What else should recovery documentation include?
- Export known-good configuration off-device
- Practice restoration on compatible hardware
- Verify backup integrity and readability
- Include dependencies and device inventory
Explanation
Correct Answer
D:Capture the hardware, licensing, physical mapping and service prerequisites. Recovery plans should record optics, license, image, model and downstream mapping, not only text configuration.
Incorrect Answers
A:A remote backup survives device loss better than only an on-switch checkpoint. But this does not address the case requirement to rebuild the usable network, not just paste commands.
B:Restore testing confirms syntax and platform compatibility rather than assuming a backup is usable. But this does not address the case requirement to rebuild the usable network, not just paste commands.
C:Archived files must be complete, accessible, correct version and free of transfer corruption. But this does not address the case requirement to rebuild the usable network, not just paste commands.
Question 763
A fire destroys the network rack and every local checkpoint. What storage location would make recovery possible?
- Encrypt and control access to backups
- Retain protected history with version tags
- Verify backup integrity and readability
- Export known-good configuration off-device
Explanation
Correct Answer
D:Maintain an independent off-device configuration backup. A remote backup survives device loss better than only an on-switch checkpoint.
Incorrect Answers
A:Configuration archives can contain management addresses and sensitive service settings. But this does not address the case requirement to protect against whole-device loss.
B:A backup policy should preserve multiple approved versions, timestamps and device identities. But this does not address the case requirement to protect against whole-device loss.
C:Archived files must be complete, accessible, correct version and free of transfer corruption. But this does not address the case requirement to protect against whole-device loss.
Question 764
A copied backup has truncated lines due to a failed transfer. What evidence can prevent using it?
- Export known-good configuration off-device
- Practice restoration on compatible hardware
- Verify backup integrity and readability
- Include dependencies and device inventory
Explanation
Correct Answer
C:Check file integrity and completeness before relying on backup. Archived files must be complete, accessible, correct version and free of transfer corruption.
Incorrect Answers
A:A remote backup survives device loss better than only an on-switch checkpoint. But this does not address the case requirement to confirm readable and complete configuration.
B:Restore testing confirms syntax and platform compatibility rather than assuming a backup is usable. But this does not address the case requirement to confirm readable and complete configuration.
D:Recovery plans should record optics, license, image, model and downstream mapping, not only text configuration. But this does not address the case requirement to confirm readable and complete configuration.
Question 765
A restoration plan has never been exercised and depends on an unsupported transceiver SKU. What should occur during readiness review?
- Retain protected history with version tags
- Export known-good configuration off-device
- Encrypt and control access to backups
- Practice restoration on compatible hardware
Explanation
Correct Answer
D:Run an actual compatible hardware restore rehearsal. Restore testing confirms syntax and platform compatibility rather than assuming a backup is usable.
Incorrect Answers
A:A backup policy should preserve multiple approved versions, timestamps and device identities. But this does not address the case requirement to verify recovery steps and device prerequisites.
B:A remote backup survives device loss better than only an on-switch checkpoint. But this does not address the case requirement to verify recovery steps and device prerequisites.
C:Configuration archives can contain management addresses and sensitive service settings. But this does not address the case requirement to verify recovery steps and device prerequisites.
Question 766
A core change is marked done even though VPN clients cannot connect, despite healthy management ping. What acceptance check is missing?
- Update capacity and lifecycle forecast
- Record objective performance baseline
- Check functional service acceptance
- Keep approved software and policy inventory current
Explanation
Correct Answer
C:Test representative user traffic and required protocol paths. Validate the endpoints, protocol adjacencies and traffic paths that users actually depend on.
Incorrect Answers
A:Growth in ports, optics, PoE and uplink throughput should influence future upgrade planning. But this does not address the case requirement to validate real service outcome.
B:Capture utilization, errors, loss, latency and application transaction measurements after maintenance. But this does not address the case requirement to validate real service outcome.
D:Maintain records of running image, configurations, owned role and group membership. But this does not address the case requirement to validate real service outcome.
Question 767
Operations cannot tell whether scheduled QoS tuning reduced delay because no counters were saved. What evidence should be recorded?
- Check functional service acceptance
- Record objective performance baseline
- Review change incidents for systemic causes
- Consolidate support handoff details
Explanation
Correct Answer
B:Capture and compare service performance statistics at closeout. Capture utilization, errors, loss, latency and application transaction measurements after maintenance.
Incorrect Answers
A:Validate the endpoints, protocol adjacencies and traffic paths that users actually depend on. But this does not address the case requirement to show objective effectiveness of tuning.
C:Repeated events warrant root cause and prevention rather than only immediate patching. But this does not address the case requirement to show objective effectiveness of tuning.
D:Document accepted configurations, alarms, escalation contacts and remaining work. But this does not address the case requirement to show objective effectiveness of tuning.
Question 768
The switch room has no spare PoE capacity as endpoint count grows each quarter. What plan should be updated?
- Record objective performance baseline
- Review change incidents for systemic causes
- Update capacity and lifecycle forecast
- Keep approved software and policy inventory current
Explanation
Correct Answer
C:Revise the capacity forecast for powered ports, budget and uplinks. Growth in ports, optics, PoE and uplink throughput should influence future upgrade planning.
Incorrect Answers
A:Capture utilization, errors, loss, latency and application transaction measurements after maintenance. But this does not address the case requirement to anticipate future network constraints.
B:Repeated events warrant root cause and prevention rather than only immediate patching. But this does not address the case requirement to anticipate future network constraints.
