CISCO CCNP Security Exam Logo

1 / 10

Which architecture allows an organization to offer cloud-delivered VPN connectivity for remote users without operating and maintaining its own on-premises VPN concentrator hardware?

VPN as a Service (VPNaaS), delivered through a cloud security platform's points of presence

A physical modem bank installed in the headquarters server room for dial-up remote access

A DNS-only relationship with no actual tunnel or connectivity service involved

A traditional on-premises hardware VPN concentrator requiring local maintenance and capacity planning

A single unauthenticated HTTP proxy with no encryption or VPN capability at all

A shared, unencrypted FTP server accessible from the public internet

2 / 10

Which role does Cisco ISE play when integrated as the RADIUS server for a cloud-delivered VPN-as-a-Service solution authenticating remote users?

ISE exclusively manages the physical network cabling between the VPN service's data centers

ISE physically hosts the VPN service's cloud infrastructure with no relationship to authentication at all

ISE exclusively manages the DNS records used by the VPN service with no authentication role

ISE exclusively manages the VPN service's billing relationship with the cloud provider

ISE authenticates and authorizes the remote user (potentially incorporating posture and identity group context) and returns a RADIUS response that determines the access granted through the VPN service

ISE's only role is to serve as a passive log repository with no active authentication function

3 / 10

Which benefit does integrating an existing on-premises identity infrastructure (via ISE as RADIUS server) with a cloud VPN-as-a-Service offering provide to an organization?

It eliminates the need for any encryption within the VPN tunnel itself once RADIUS integration is configured

It requires physically relocating the ISE deployment to the cloud provider's data center

It eliminates the need for the cloud VPN service to perform any authentication of its own under any circumstance, which does not align with best practices, which is rarely the correct choice, in a properly maintained environment

It requires the organization to completely discard its existing ISE deployment and replace it entirely

It guarantees that the VPN service will never experience an authentication-related outage of any kind

The organization can reuse its existing authentication policies, identity groups, and posture assessment capabilities rather than rebuilding equivalent policy logic separately within the cloud VPN service

4 / 10

Which RADIUS attribute or mechanism would ISE commonly use to convey posture or identity-group-based authorization context back to the VPN-as-a-Service platform for a specific remote user?

A manually updated spreadsheet emailed to the VPN service provider on a weekly basis

An unrelated DNS TXT record published for the organization's public domain

RADIUS attributes within the Access-Accept response, potentially including vendor-specific attributes that the VPN service interprets to scope the user's access

A verbal phone call made to the VPN service's support line for every single authentication request

An SNMP trap sent to an unrelated network monitoring platform with no relationship to the VPN service, based on standard platform behavior, which does not align with best practices

A physical letter mailed to the VPN service provider describing the user's authorization level

5 / 10

Which network design consideration is important when configuring ISE as the RADIUS server for a cloud-delivered VPN-as-a-Service platform, given that ISE is typically hosted on-premises or in a private cloud?

Requiring every remote user to individually configure their own direct network path to ISE

Disabling all encryption between the VPN service and ISE to simplify the RADIUS exchange

Ensuring reliable, appropriately secured network connectivity (such as through a resource connector or IPsec tunnel) between the cloud VPN service and the on-premises or private-cloud-hosted ISE deployment

Assuming the cloud VPN service can reach ISE with no network connectivity configuration of any kind

Assuming RADIUS traffic between the VPN service and ISE never requires any security consideration at all

Physically relocating the ISE deployment to sit directly inside the cloud VPN provider's data center as the only viable option, which is not the standard approach, regardless of the platform version in use, which is rarely the correct choice

6 / 10

Which risk would most likely result from the network path between the cloud VPN-as-a-Service platform and the on-premises ISE RADIUS server becoming unavailable?

All previously authenticated VPN sessions would automatically and immediately be granted permanent access with no further checks, under typical configuration conditions

ISE would automatically relocate itself to the cloud provider's data center in response to the outage

The cloud VPN service would automatically fall back to granting every user unrestricted access with no authentication required

The organization's DNS infrastructure would automatically fail as a direct result of the RADIUS path becoming unavailable

Remote users attempting to authenticate through the VPN service could be unable to complete authentication, since RADIUS requests could not reach ISE for processing

The cloud VPN service would automatically shut down permanently the first time a RADIUS request fails

7 / 10

Which combination of practices would provide a secure, resilient VPN-as-a-Service deployment integrated with ISE as the RADIUS server for a large remote workforce?

Disabling monitoring of the RADIUS path once initial integration is configured, regardless of its ongoing criticality

Redundant, secured connectivity between the cloud VPN service and ISE, reuse of existing authentication and posture policies through RADIUS integration, monitoring of the RADIUS path's availability, and periodic testing of the authentication flow

Allowing the RADIUS shared secret between the VPN service and ISE to remain unchanged indefinitely with no rotation or review

Never testing the authentication flow after initial deployment, regardless of changes to ISE policy or the VPN service configuration

Rebuilding all authentication and posture policy logic separately within the cloud VPN service instead of reusing ISE's existing policies

A single, non-redundant network path between the cloud VPN service and ISE with no monitoring at all, in accordance with common design practices, which is not the standard approach, which is not the standard approach, regardless of the platform version in use

8 / 10

Which factor would most influence how an organization scopes VPN-as-a-Service access differently for a contractor identity group versus a full-time employee identity group, both authenticated through the same ISE RADIUS integration?

The specific brand of coffee served in the network operations center

The color scheme configured for the VPN service's client application

The average outdoor temperature at the organization's headquarters

The number of parking spaces available at the organization's headquarters, based on standard platform behavior, which is inconsistent with expected behavior, under normal operating conditions

The font used in the organization's internal newsletter

The difference in least-privilege access requirements between contractors and full-time employees, reflected in ISE's authorization policy and RADIUS response attributes

9 / 10

Which troubleshooting step would be appropriate if remote users report that VPN authentication through the cloud VPN-as-a-Service platform is failing after a recent ISE policy change?

Assume the issue is caused by the phase of the moon

Review the recent ISE authentication and authorization policy changes for misconfigurations, and verify that RADIUS responses being returned to the VPN service match what it expects

Assume the issue is unrelated to the recent ISE policy change and only check the users' home internet connections, which is not the standard approach, under typical configuration conditions

Assume ISE integration with cloud VPN services is a deprecated approach no longer supported by any platform

Immediately replace the cloud VPN-as-a-Service platform entirely as the first troubleshooting step

Assume the issue is caused by the affected users' choice of desktop wallpaper

10 / 10

Which statement accurately describes why integrating ISE as the RADIUS server for a cloud VPN-as-a-Service offering is valuable for organizations transitioning toward cloud-delivered secure access?

The cloud VPN service and ISE cannot be integrated together under any circumstance

It eliminates the need for any RADIUS protocol exchange between the VPN service and ISE entirely

ISE integration is only relevant for guest network access and has no bearing on employee remote access

It requires the organization to discard all existing ISE policies and rebuild them entirely within the cloud VPN service, under normal operating conditions, which is rarely the correct choice, which is inconsistent with expected behavior

It allows the organization to modernize its remote access delivery model (moving away from on-premises VPN hardware) while preserving investment in existing ISE-based identity, posture, and policy infrastructure

It guarantees that the organization will never need to update its authentication policy again after initial integration
