A multinational corporation is deploying Cisco ISE to enforce network access for both wired and wireless users. The company has 5,000 employees and 2,000 guest users daily. The ISE deployment consists of two nodes: a primary Administration Node (PAN) and a Monitoring Node (MNT). All policies are configured on the PAN. Recently, the company has experienced intermittent authentication failures during peak hours. The failures affect both wired 802.1X and wireless users. The syslogs show 'RADIUS request dropped' messages on the ISE nodes. The network team has verified that the RADIUS shared secret is correct and that the network devices can reach the ISE nodes. The ISE nodes have sufficient CPU and memory. However, the authentication failures correlate with times when the number of concurrent sessions exceeds 500. What is the most likely cause of the issue?

A university is using Cisco ISE to provide secure wireless access for students and faculty. The wireless network uses WPA2-Enterprise with PEAP-MSCHAPv2. Recently, some faculty members reported that they cannot connect to the wireless network from their personal laptops, while student devices connect without issues. The faculty members are using the same SSID and entering their credentials correctly. The ISE logs show that the authentication attempts from faculty devices are failing with 'RADIUS Access-Reject' due to incorrect credentials. However, the faculty members are certain they are using the correct password. The IT department has verified that the user accounts in Active Directory are active and not locked. What is the most likely cause of the issue?

What is the most likely reason?

A large enterprise has deployed Cisco ISE for network access control. The network consists of multiple access switches and wireless LAN controllers. The security team wants to enforce that only domain-joined Windows computers with up-to-date antivirus can access the corporate network. Non-compliant devices should be placed in a quarantine VLAN with limited access to remediation servers. The ISE policies are configured with posture assessment. However, during a test, a non-compliant Windows computer is granted full network access instead of being quarantined. The ISE logs show that the posture assessment passed, but the computer's antivirus is outdated. What is the most likely reason for this behavior?

A network administrator is troubleshooting an issue where users in the Sales VLAN cannot access the internet through the Cisco Firepower Threat Defense (FTD) device. The FTD is configured with a security policy that allows traffic from the Sales subnet to any destination. However, the traffic is being blocked.

An ISE deployment uses TrustSec with SGTs assigned by Active Directory group membership. A group of users in the 'Finance' AD group is correctly receiving SGT 5, but a new user added to that group is getting SGT 0. The ISE policy is unchanged, and other users in the group work fine. What is the most likely cause?

A network administrator wants to implement 802.1X authentication on a switch port that connects a printer. The printer does not support 802.1X, so the administrator configures MAC Authentication Bypass (MAB) as a fallback method. Which command must be included in the switch port configuration to ensure MAB is attempted after 802.1X times out?

An engineer is troubleshooting a user who cannot access the network after successful 802.1X authentication. The user's PC receives an IP address from DHCP, but cannot reach the internet.

A large enterprise has deployed Cisco ISE for network access control with 802.1X and MAB across its wired and wireless networks. The network consists of Cisco Catalyst switches, Cisco Wireless LAN Controllers (WLCs), and ISE in a distributed deployment with three Policy Service Nodes (PSNs) and an Admin Node. Recently, the company implemented a new security policy requiring all endpoints to pass posture assessment before gaining full network access. The posture assessment uses AnyConnect ISE Posture Module. Shortly after the change, users report that some wired clients are unable to connect to the network. The ISE logs show that the authentication is successful, but the session is terminated immediately with a 'Session-Timeout' attribute set to 0. The network team notices that the affected clients are all connected to switches running older Cisco IOS versions. The ISE administrator confirms that the authorization profiles for the affected clients include a session-timeout of 1 hour. Which course of action should the network engineer take to resolve the issue?

During testing, the engineer notices that the posture agent reports 'NAC Agent: Posture Unknown' for those laptops. What is the most likely cause?

A large enterprise uses Cisco ISE with pxGrid to share context with Firepower for threat containment. When a Firepower detects an infected endpoint, it triggers a pxGrid quarantine action that changes the endpoint's authorization profile. The engineer observes that the quarantine is applied, but after the Firepower clears the threat, the endpoint does not regain its original access. What is the most likely reason?

Which TWO factors should be considered when designing a Cisco ISE deployment for network access control (NAC) in a multi-site environment? (Choose two.)

Which THREE capabilities are provided by Cisco ISE's visibility services within the Secure Network Access domain? (Choose three.)

A hospital is deploying Cisco ISE for network access control. They have a mix of employee laptops, medical devices (e.g., infusion pumps), and guest smartphones. The network uses Cisco Catalyst 9300 switches and Aironet 3700 series access points. For medical devices, the policy must use Machine Authentication (MAB) since they are 802.1X incapable. The ISE policy authenticates via MAB and then assigns the device to a specific VLAN for medical devices. During a pilot, the network team notices that some infusion pumps (MAC: 00:1A:2B:3C:4D:5E) are failing MAB authentication. The switch logs show 'Authentication failed for MAC 001a.2b3c.4d5e on interface GigabitEthernet1/0/10'. ISE logs show 'Authentication failed - RADIUS server rejected - Reason: Invalid Endpoint ID'. The engineer has verified the MAC address is in the ISE endpoint repository with correct identity group. What should the engineer check next to resolve this issue?

A university is implementing 802.1X for student wireless networks using Cisco Wireless LAN Controllers (WLCs) and ISE. Students connect with their personal devices using PEAP-MSCHAPv2. During heavy usage, some students report authentication failures and sporadic disconnections. The network team examines the ISE live logs and sees many 'Authentication failed' entries with reason 'Internal error - unable to find a suitable proxy target'. The team has configured two ISE nodes as authentication proxies for the wireless subnets. What is the most likely cause of this issue?

A financial company is deploying Cisco ISE with TrustSec to enforce segmentation between application tiers (web, app, DB). They have a Cisco Catalyst 9500 as the core, and Catalyst 9300s as access switches. The SXP is configured between ISE and core switch, and the core switch propagates SGTs to access switches via SGT inline tagging on trunk ports. The engineer has configured SGTs for web (SGT=2), app (SGT=3), DB (SGT=4). However, when testing from a web server (IP 10.1.1.10, SGT=2) to an app server (IP 10.1.2.20, SGT=3), the app server sees the traffic without SGT in the packet, so the access switch cannot enforce policy. The engineer checks 'show cts role-based sgt-map' on the core and sees the mapping for 10.1.1.10 -> 2. What is the most likely issue?

A small business uses Cisco ISE to authenticate employees via Active Directory. The company has a single ISE node and two Catalyst 2960-X switches. Employees connect to the network and are successfully authenticated using 802.1X with PEAP. The business wants to provide guest wireless access using a separate SSID with a captive portal. The engineer configures a new WLAN on the WLC (Cisco 2504) pointing to the same ISE node. Guest users can associate to the WLAN and get an IP address, but when they open a browser, they do not see the captive portal page; instead, they get a 'Connection refused' error. The engineer verifies that the guest portal is enabled on ISE and the WLC is configured to use ISE for RADIUS. What is the most likely cause?

A multinational corporation is implementing ISE for wired network access using 802.1X with EAP-TLS certificate authentication. Their Windows 10 laptops have certificates issued by an internal PKI. During testing, some users report that they are repeatedly prompted to select a certificate after connecting, and eventually authentication fails. ISE logs show 'Authentication failed - No matching certificate found'. The engineer checks the client machine and sees multiple certificates, including the correct one, in the personal store. The ISE endpoint identity store is populated with the user's AD credentials. What is the most likely cause of this failure?

A government agency is deploying Cisco ISE with a posture agent to ensure endpoints comply with security policies before accessing the network. The posture policy requires that all Windows computers have antivirus (AV) software running. The engineer configures a condition 'AV installed and running' and binds it to an authorization profile that grants full access if compliant, or quarantine if not. During testing, a computer that has AV installed and running (verified manually) is placed in quarantine. ISE logs show 'Posture - AV condition not satisfied'. The engineer checks the ISE posture configuration: the AV condition uses a default Cisco AV dictionary. What is the most likely cause?

A network administrator is configuring 802.1X for wired access on a Cisco switch. The switch is configured for RADIUS using a Cisco ISE server. During testing, a client that supports 802.1X is unable to authenticate and fails to gain network access. The administrator checks the switch logs and sees "Authentication failed: invalid EAP code received". What is the most likely cause?

A Cisco TrustSec deployment is being implemented to enforce micro-segmentation. The security team needs to ensure that Security Group Tags (SGTs) are propagated across the network. Which THREE methods can be used to distribute SGT information in a TrustSec environment? (Choose three.)
