Cisco 300-715 Practice Test 10
Question 90
An enterprise reuses an old SNS platform and expects every current node persona and licensing feature to work. The observed failure is: An end-of-support platform may not run a new ISE build even if the old release still boots. How should the administrator correct and verify this failure?
- The supported recovery is to use a report template change as a substitute for SNS hardware migration.
- The supported recovery is to assume any appliance with Cisco branding supports all ISE versions.
- The supported recovery is to choose a supported target platform and migrate or upgrade under a tested rollback plan.
- The supported recovery is to skip version compatibility checks because the host responds to ping.
Explanation
Correct Answer
C:ISE installation and upgrade support depends on specific hardware and software combinations. Recheck target ISE version, SNS model, support matrix, installation checks and documented upgrade path.
Incorrect Answers
A:Use a report template change as a substitute for SNS hardware migration. This action does not repair the identified failure. An end-of-support platform may not run a new ISE build even if the old release still boots. Instead, choose a supported target platform and migrate or upgrade under a tested rollback plan. For the specific situation, an enterprise reuses an old SNS platform and expects every current node persona and licensing feature to work.
B:Assume any appliance with Cisco branding supports all ISE versions. This action does not repair the identified failure.

Question 91
An ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it. Which configuration decision most directly satisfies the requirement?
- Prepare the supported bootstrap address, network reachability, provisioning artifact and documented initial configuration flow.
- Assume a fresh unconfigured appliance knows the complete enterprise policy automatically.
- Place bootstrap artifacts on an unreachable management network.
- Disable initial identity verification to make remote deployment faster.
Explanation
Correct Answer
A:Verify the effect through bootstrap server reachability, network DHCP and DNS state, provisioning input, startup logs and node registration. For the specific situation, an ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it.
Incorrect Answers
B:Merely placing an appliance on a network does not guarantee it receives authenticated deployment settings. This does not implement the required control for ISE zero-touch bootstrap prerequisites.
C:Place bootstrap artifacts on an unreachable management network. This alternative overlooks a required prerequisite or targets the wrong function. Zero-touch provisioning automates initial setup only when trusted discovery and configuration prerequisites are available. The relevant evidence is bootstrap server reachability, network DHCP and DNS state, provisioning input, startup logs and node registration. For the specific situation, an ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it.
D:Merely placing an appliance on a network does not guarantee it receives authenticated deployment settings. For the specific situation, an ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it.
Question 92
An ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it. What observations most directly test this network-access condition?

- An old diagram with no RADIUS, TACACS+ or endpoint-session evidence.
- A current login screenshot from a completely unrelated ISE deployment.
Explanation
Correct Answer
A:These observations directly establish the result of ISE zero-touch bootstrap prerequisites for the described endpoint or network device. For the specific situation, an ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it.

Question 93
An ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it. What principle of ISE authentication and authorization explains this case?

- A captive portal page automatically changes network authorization on every active NAD session without signaling.
- A successful switch port link signal always proves the device identity and policy were verified.
- Every RADIUS Access-Accept grants unrestricted access to all applications.
Explanation

C:This generalization is not valid for ISE zero-touch bootstrap prerequisites. For the specific situation, an ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it.
D:This generalization is not valid for ISE zero-touch bootstrap prerequisites. Verify the actual state using bootstrap server reachability, network DHCP and DNS state, provisioning input, startup logs and node registration.
Question 94
An ISE appliance is powered on remotely but zero-touch initialization fails because discovery services cannot reach it. An operator proposes the following incorrect shortcut: Assume a fresh unconfigured appliance knows the complete enterprise policy automatically. Which negative consequence BEST explains the shortcut’s flaw?
- Reading the authentication event report caused the original network access outage.
- Merely placing an appliance on a network does not guarantee it receives authenticated deployment settings.
- The only result is an unrelated portal background color change.
- Accurate device accounting automatically created every earlier failed EAP exchange.
Explanation
