Question 120
A multi-node ISE site needs documented configuration recovery that does not confuse node redundancy with full backups. The observed failure is: Replicated mistakes or deleted policies can persist on all nodes when no independent backup exists. Which controlled recovery BEST restores the intended state?
- The supported recovery is to delete all configuration archives once a second PSN is installed.
- The supported recovery is to restore from an approved point after validating backup integrity and the target version requirements.
- The supported recovery is to assume a standby PAN is an immutable historical backup of every policy.
- The supported recovery is to store backup encryption keys openly in a guest portal.
Explanation
Correct Answer
B:Redundant ISE nodes help availability but do not replace recoverable configuration and data backups. For the specific situation, a multi-node ISE site needs documented configuration recovery that does not confuse node redundancy with full backups.
Incorrect Answers
A:Delete all configuration archives once a second PSN is installed. This action does not repair the identified failure. Replicated mistakes or deleted policies can persist on all nodes when no independent backup exists. Instead, restore from an approved point after validating backup integrity and the target version requirements. For the specific situation, a multi-node ISE site needs documented configuration recovery that does not confuse node redundancy with full backups.
C:Assume a standby PAN is an immutable historical backup of every policy. This action does not repair the identified failure. Replicated mistakes or deleted policies can persist on all nodes when no independent backup exists. Instead, restore from an approved point after validating backup integrity and the target version requirements. For the specific situation, a multi-node ISE site needs documented configuration recovery that does not confuse node redundancy with full backups.
D:Store backup encryption keys openly in a guest portal. This action does not repair the identified failure. Replicated mistakes or deleted policies can persist on all nodes when no independent backup exists.

For the specific situation, a multi-node ISE site needs documented configuration recovery that does not confuse node redundancy with full backups.
Question 121
A corporate ISE deployment cannot query domain accounts because the selected domain join is incomplete. What is the BEST supported ISE implementation or corrective action?
- Point AD queries only at a public resolver with no internal SRV records.
- Assume a local ISE administrator login verifies AD integration.
- Join ISE to the intended AD domain with valid DNS, time, join privileges and healthy controller reachability.
- Disable Kerberos clock validation across the domain to hide time errors.
Explanation
Correct Answer
C:This is the targeted action for ISE join to Active Directory and domain controller discovery. For the specific situation, a corporate ISE deployment cannot query domain accounts because the selected domain join is incomplete.
Incorrect Answers
A:This does not implement the required control for ISE join to Active Directory and domain controller discovery. A reachable ISE admin GUI does not prove the AD connector can authenticate remote accounts.
B:Assume a local ISE administrator login verifies AD integration. This alternative overlooks a required prerequisite or targets the wrong function. Using an AD identity source requires functioning domain integration and reachable directory services. The relevant evidence is aD domain join state, DNS SRV lookup, Kerberos time, operational logs and AD test authentication. For the specific situation, a corporate ISE deployment cannot query domain accounts because the selected domain join is incomplete.
D:A reachable ISE admin GUI does not prove the AD connector can authenticate remote accounts. For the specific situation, a corporate ISE deployment cannot query domain accounts because the selected domain join is incomplete.
Question 122
A corporate ISE deployment cannot query domain accounts because the selected domain join is incomplete. Which evidence BEST verifies the intended operational outcome?
- A switch interface description without any live AAA request or response.
- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
- A current login screenshot from a completely unrelated ISE deployment.
- AD domain join state, DNS SRV lookup, Kerberos time, operational logs and AD test authentication.
Explanation

Question 123
A corporate ISE deployment cannot query domain accounts because the selected domain join is incomplete. Which technical principle BEST explains the required decision?

- Using an AD identity source requires functioning domain integration and reachable directory services.
- Every RADIUS Access-Accept grants unrestricted access to all applications.

Question 124
A corporate ISE deployment cannot query domain accounts because the selected domain join is incomplete. An operator proposes the following incorrect shortcut: Point AD queries only at a public resolver with no internal SRV records. What material risk or failure follows from that shortcut?
- Reading the authentication event report caused the original network access outage.
- The only result is an unrelated portal background color change.
- A reachable ISE admin GUI does not prove the AD connector can authenticate remote accounts.
- Accurate device accounting automatically created every earlier failed EAP exchange.
Explanation
