ACP Communication & Documentation 3 — Questions and Answers
Question 1: When escalating an Aruba ClearPass authentication issue to Tier 3 support, which information should be included FIRST in the escalation communication?
- A summary of symptoms, steps already taken, and affected user count (Correct answer)
- The full raw syslog export without context
- A request to replace all hardware
- The procurement invoice for ClearPass
Correct answer: A summary of symptoms, steps already taken, and affected user count
An effective escalation starts with a concise summary of symptoms, troubleshooting done, and scope of impact.
Question 2: Which diagram type is MOST appropriate for documenting Aruba controller cluster failover relationships?
- Floor plan diagram
- Logical network diagram (Correct answer)
- Rack elevation diagram
- Gantt chart
Correct answer: Logical network diagram
A logical network diagram shows relationships and failover dependencies between network devices.
Question 3: An organization requires that all Aruba network changes be communicated to end users 48 hours in advance. Which channel is MOST appropriate for broad user notification?
- Direct message to each individual user
- Company-wide email or intranet announcement (Correct answer)
- Chat with the network team only
- Post on the engineer's personal social media
Correct answer: Company-wide email or intranet announcement
A company-wide email or intranet post ensures broad reach and creates a documented communication record.
Question 4: What is the purpose of a network baseline document in an Aruba environment?
- To list available IP addresses for future allocation
- To record normal performance metrics for comparison during troubleshooting (Correct answer)
- To document the initial hardware purchase price
- To describe the physical cabling color scheme
Correct answer: To record normal performance metrics for comparison during troubleshooting
A baseline document records normal operating metrics so deviations can be quickly identified during incidents.
Question 5: Which Aruba AOS-CX command output is MOST important to capture in a troubleshooting ticket for an inter-VLAN routing issue?
- show lldp neighbors
- show ip route (Correct answer)
- show environment fans
- show spanning-tree detail
Correct answer: show ip route
The 'show ip route' output reveals the routing table state, which is central to diagnosing inter-VLAN routing failures.
Question 6: A change management process requires a 'back-out plan' for all Aruba configurations. What does this document describe?
- The exit interview process for departing engineers
- Steps to revert the change if it causes problems (Correct answer)
- The physical removal procedure for hardware
- The plan to back up data before the change
Correct answer: Steps to revert the change if it causes problems
A back-out plan documents the exact steps to undo a change if it results in unintended consequences.
Question 7: Which SLA metric is MOST relevant to document when defining acceptable Aruba wireless network performance for a hospital environment?
- Number of VLANs configured
- Maximum tolerable latency for clinical applications (Correct answer)
- Model numbers of installed APs
- SSID broadcast power levels
Correct answer: Maximum tolerable latency for clinical applications
Maximum tolerable latency directly impacts clinical application performance and patient safety, making it the critical SLA metric.
