QUESTION 39
Refer to the exhibit.

An engineer must configure Cisco ThousandEyes SSO to use Microsoft Entra ID using the configuration shown in the exhibit. Which feature must be set to override to complete the configuration?

Service Provider Issuer

Logout Page URL

Identity Provider Issuer

In the Designing and Implementing Enterprise Network Assurance (300-445 ENNA) architecture, secure administrative access via Single Sign-On (SSO) is a critical component of platform governance. The exhibit illustrates the ThousandEyes SSO configuration panel being integrated with Microsoft Entra ID (formerly Azure AD). When configuring SAML-based authentication, the ” Identity Provider Issuer ” (Option D) is a unique identifier provided by the IdP (Microsoft) that must match exactly between the two systems.
According to ENNA implementation guidelines, ThousandEyes populates default fields based on standard SAML metadata. However, Microsoft Entra ID often utilizes a specific GUID-based format for the Issuer URL (e.g., https://sts.windows.net/tenant-id/) that may differ from the generic URL format expected by the platform ‘ s initial auto-fill. To ensure a successful SAML handshake, the engineer must select the ” Override
” checkbox next to the Identity Provider Issuer field. This action unlocks the field, allowing the engineer to manually paste the exact string provided in the Entra ID Federation Metadata document. If this value is not overridden and matched precisely, the SAML assertion will be rejected, resulting in a failed authentication attempt.
While the Login and Logout URLs (Options B and C) are also critical, they are typically correctly identified during the initial setup or metadata import; the Identity Provider Issuer is the most frequent point of mismatch requiring an manual override in Entra ID environments due to its strict ” Audience Restriction ” requirements. The Service Provider Issuer (Option A) is generally a fixed value (https://app.thousandeyes.
com) that rarely requires overriding as it defines ThousandEyes ‘ own identity to the IdP.
Therefore, selecting the override for the Identity Provider Issuer is the necessary step to complete the integration and allow enterprise users to authenticate securely using their corporate credentials.

QUESTION 43
Refer to the exhibit.

An engineer must use Cisco ThousandEyes testing to monitor their Cisco Catalyst SD-WAN fabric. Which SD-WAN component is being monitored by ThousandEyes?

underlay

IPsec tunnels

overlay

GRE tunnels

In theDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)curriculum, understanding the visibility gap between the SD-WAN overlay and the transport underlay is a core competency. The provided exhibit illustrates a ThousandEyes Enterprise Agent deployed on aBranch Edge Routerperforming tests across two distinct paths:Internet(reaching a destination at 64.100.249.90) andMPLS (reaching a destination at 172.29.0.2).
According to the ENNA architecture guidelines, ThousandEyes is primarily utilized to provide hop-by-hop visibility into theunderlaynetwork. While SD-WAN controllers like vManage provide native monitoring for the overlay-the logical IPsec tunnels (Option B) that form the SD-WAN fabric-they often lack granular visibility into the physical service provider paths (the underlay) that carry those tunnels. The exhibit specifically highlights the agent probing the transport networks (Transport VPN0) directly, bypassing the overlay tunnels to measure the raw performance of the ISP and MPLS circuits.
By monitoring theunderlay(Option A), the engineer can identify if high latency or packet loss is caused by a specific hop within the service provider’s infrastructure or at a peering point. This “underlay visibility” is critical for troubleshooting SD-WAN performance issues where the overlay may report a tunnel down, but the root cause lies in a BGP routing change or physical fiber cut in the provider network. ThousandEyes Enterprise Agents, natively integrated into Catalyst 8000 and ISR 4000 platforms, allow for this persistent underlay monitoring without additional hardware.
* Overlay (Option C):While ThousandEyes can monitor overlay performance, the exhibit’s focus on the raw IP addresses (Internet and MPLS) in the transport VPN indicates an underlay test.
* IPsec/GRE Tunnels (Options B & D):These represent the transport mechanisms of the overlay.
ThousandEyes probes the pathunderthese tunnels to ensure the transport health is sufficient to support the fabric.
