Practice this domainAn engineer is configuring a Cisco ASA and needs to ensure that traffic from the outside interface to a web server on the DMZ is allowed. The inside interface is security level 100 and the DMZ is level 50. The outside interface is level 0. Which statement about the default traffic flow is true?
Traffic from outside to DMZ is allowed implicitly because the ASA inspects all interfaces equally.
Traffic from outside to DMZ is denied implicitly because outside level is lower than DMZ level.
Correct. ASA defaults deny traffic from lower to higher security levels.
Traffic from outside to DMZ is allowed implicitly because outside is level 0 and DMZ is level 50.
Traffic from outside to DMZ is allowed implicitly because both are lower than inside.
A network administrator is configuring NAT on a Cisco ASA to allow internal users to access the internet using a single public IP address. The internal network uses RFC 1918 addresses. Which type of NAT should be configured?
Dynamic NAT
Static NAT
Identity NAT
PAT (Port Address Translation)
PAT overloads a single IP by using unique port numbers.
An engineer is configuring a Modular Policy Framework (MPF) on a Cisco ASA to inspect HTTP traffic and apply QoS. The engineer creates a class-map to match HTTP traffic using the 'match port tcp 80' command. However, the policy is not being applied correctly. What is the most likely reason?
The class-map should use 'match any' instead of 'match port tcp 80'.
The ASA does not support HTTP inspection via MPF.
The service-policy must be applied globally, not to an interface.
The default global inspection policy already inspects HTTP traffic, and the new policy may be overridden.
The default policy inspects HTTP; the new policy must be inserted before it or the default must be modified.
A company uses Cisco Firepower Threat Defense (FTD) managed by FMC. They need to create an access control policy that allows traffic from specific source IPs to a web server, but blocks all other traffic. How should the rule base be ordered?
Place the block rule first, then the permit rule.
Place the permit rule first, then the block rule.
The permit rule matches first for allowed sources; the block rule catches all others.
Use a single rule with permit and block conditions combined.
Order does not matter because FMC processes rules in parallel.
A security administrator is investigating an alert from an IPS that detected a SQL injection attempt. The alert was triggered by a signature that looks for specific patterns in the traffic. What type of detection method is this?
Signature-based detection
Signature-based detection matches traffic against known attack patterns.
Behavioral detection
Heuristic detection
Anomaly-based detection
A Cisco Firepower administrator configures an access control policy with a rule that trusts traffic from a specific source network. What is the effect of the trust action on the traffic?
The traffic is blocked and logged.
The traffic is allowed without further inspection.
Trust action permits traffic and skips additional inspection.
The traffic is allowed and inspected by the intrusion policy.
The traffic is allowed but subject to file policy.

Secure Internet Gateway (SIG)
Intelligent Proxy
Intelligent Proxy allows selective proxying and SSL decryption based on policy.
Umbrella Roaming Client
A company is deploying a multi-tier application in a Cisco cloud security environment. The web servers must be accessible from the internet, but the database servers should only be reachable from the web servers. Which Cisco security controls should be used to enforce this?
Use Cisco ASA access-lists to allow inbound traffic to web servers from 0.0.0.0/0 and deny all traffic to database servers
Assign a Cisco TrustSec security group tag (SGT) to web servers allowing HTTP/S from 0.0.0.0/0, and a separate SGT for databases allowing traffic only from the web server SGT
Correct. Firepower access control rules are stateful and can reference source IPs or security zones to precisely allow only web server traffic to databases.
Place web servers in a public subnet and database servers in a private subnet, and use a Cisco Firepower access control policy to block all traffic to the private subnet
Use Cisco CloudLock to restrict access to database servers based on source IP
An organization wants to implement zero trust principles for cloud access. Which of the following is a key component of a zero trust architecture in the cloud?

Practice this domainA security administrator notices that a significant volume of spam is bypassing the Cisco ESA's anti-spam filters. Upon investigation, they find that the messages have a mid-range SBRS score of 5.0. Which action should the administrator take to improve spam detection?
Change the SBRS score interpretation to positive
Lower the SBRS threshold to 3.0
Increase the SBRS threshold to 7.0
Raising the threshold to 7.0 means any message with an SBRS below 7.0 is classified as spam. Since the problematic messages have a score of 5.0, they would now be caught, improving spam detection.
Disable SenderBase reputation checks
An organization is deploying Cisco ESA and wants to ensure that outbound emails containing credit card numbers are blocked. The administrator configures a DLP policy to scan for credit card patterns. However, some legitimate emails with credit card numbers are being incorrectly blocked. What is the best approach to reduce false positives while still preventing data leakage?
Disable the DLP policy for outbound email
Change the DLP action from 'Block' to 'Confirm with Sender'
This allows the sender to confirm the email is legitimate, reducing false positives while maintaining oversight.
Increase the DLP sensitivity threshold
Add all senders to a DLP exemption list
A Cisco WSA administrator wants to block access to social media sites for all users during work hours. The proxy is deployed in explicit mode. Which policy type should the administrator use to enforce this restriction?
Access policy
Access policies enforce rules on URL filtering, application control, and time-based restrictions.
Identity policy
Routing policy
Decryption policy
Which Cisco content security solution uses DNS to block access to malicious domains and provides cloud-based proxy protection?
Cisco WSA
Cisco ESA
Cisco Firepower NGFW
Cisco Umbrella
Umbrella provides DNS-layer security and a cloud proxy for web traffic.
An organization using Cisco WSA in transparent proxy mode with WCCP redirect notices that some HTTPS traffic is not being decrypted for inspection. The administrator has enabled SSL decryption but certain traffic still bypasses. What is the most likely cause?
The clients are not configured to use a proxy
The web server certificate is self-signed
The WSA is operating in explicit proxy mode
The SSL decryption policy is not set to decrypt on port 443
HTTPS traffic typically uses port 443. If the decryption policy does not include port 443, it will not be decrypted.
A Cisco ESA administrator is investigating an increase in false positive detections from the outbreak filter. The filter is configured to use TALOS intelligence and has a threshold of 'Medium'. Which action would most effectively reduce false positives while maintaining protection against new outbreaks?
Change the threshold to 'Low'
Change the threshold to 'High'
A higher threshold reduces false positives by requiring stronger evidence.
Disable the outbreak filter
Exempt all internal senders from the filter

A security administrator notices that several endpoints in the finance department are exhibiting unusual network behavior, including connections to known malicious IP addresses. The administrator has deployed Cisco Secure Endpoint (formerly AMP for Endpoints) with TETRA and has enabled the built-in firewall. What is the best course of action to quickly identify the root cause and contain the threat?
Disable the built-in firewall on the endpoints to allow full traffic inspection by the TETRA engine.
Use the Cisco Secure Endpoint console to review the TETRA engine's real-time traffic analysis and isolate the affected endpoints.
TETRA provides real-time traffic analysis; the console allows immediate visibility and isolation.
Wait for the weekly threat report from Cisco Talos to identify the malware family and then apply a signature update.
Uninstall the Cisco Secure Endpoint connector and reinstall it with a fresh policy.
An organization wants to prevent malware from executing on endpoints by using a file reputation service. Which Cisco technology provides cloud-based file reputation and analysis for endpoint protection?
Cisco Stealthwatch
Cisco Identity Services Engine (ISE)
Cisco Firepower NGFW
Cisco Secure Endpoint (AMP for Endpoints)
Cisco Secure Endpoint provides cloud-based file reputation and analysis.
A security engineer is troubleshooting an issue where a known malicious file (SHA-256: 3a7c...f9e) is not being detected by Cisco Secure Endpoint on a Windows 10 endpoint. The file was downloaded from the internet. The policy has the 'File Reputation' setting set to 'Use cloud lookup', and the 'Exploit Prevention' module is enabled. The endpoint is connected to the internet and can reach the AMP cloud. What is the most likely reason for the missed detection?
The endpoint was offline when the file was first written to disk, so the cloud lookup was skipped.
If the endpoint was offline during file download, the initial cloud lookup is skipped, and the file is allowed.
Windows Defender Real-time Protection is interfering with the AMP connector.
The Exploit Prevention module is blocking the cloud lookup process.
The AMP cloud license has expired for the organization.
A security analyst is investigating an alert from Cisco Secure Endpoint indicating that an endpoint has been infected with ransomware. The analyst wants to determine the initial infection vector.

A network administrator is configuring Cisco ISE to enforce access control based on user authentication. The company requires that only users who authenticate via Active Directory are allowed access to the corporate wireless network. Which policy should be configured in ISE to accomplish this?
Profiling policy
Authentication policy
Authorization policy
Authorization policy defines what access is granted after authentication.
Policy set
A company uses Cisco ISE for network access control. Users connecting via wired 802.1X are successfully authenticated but cannot reach the internet. The administrator checks the authorization policy and notices that the correct dACL is being applied. What is the most likely cause of the issue?
The switchport is configured as dynamic desirable
The RADIUS server is not sending the dACL attribute in the Access-Accept
If the dACL is not included in the RADIUS response, the switch will not apply it.
The switch port MTU is set to 1500 bytes
ISE is out of licenses for endpoint devices
An organization is implementing TrustSec to enforce micro-segmentation. The Security Group Tag (SGT) is assigned to a user via ISE after authentication. However, traffic from this user to a server with SGT 5 is being dropped. The administrator checks the SGACL configuration on the switch and finds the following: 'permit ip source 2 destination 5'. What is the most likely reason for the traffic being dropped?
The PAC on the switch has expired
SXP is not configured between ISE and the switch
Correct. SXP is used to share SGT-to-IP bindings from ISE to the switch. Without SXP, the switch cannot associate the user with SGT 2, so even though an SGACL permit exists for source SGT 2 to destination SGT 5, the traffic is dropped because the switch treats the user as having an unknown SGT.
The CTRL protocol is not enabled on the switch
The SGACL defaults to deny if no explicit permit is found for the source-destination SGT pair
A company is deploying Cisco ISE for guest access. They want to provide a self-service portal where guests can register their devices and receive a temporary username and password. Which ISE component is used to accomplish this?
BYOD Portal
Mobile Device Management (MDM)
Guest Portal
Guest Portal provides self-service registration and temporary credentials for guests.
Profiler Service
An engineer is troubleshooting a Cisco ISE deployment where some endpoints are not being profiled correctly. The administrator notices that the endpoints are not sending DHCP requests. Which profiling probe should be primarily used to identify these endpoints?
NetFlow probe
NetFlow probe analyzes traffic flows and can profile endpoints based on IP and port information.
DHCP probe
HTTP probe
DNS probe
A network administrator wants to implement 802.1X on a Cisco switch port for a device that does not support 802.1X. Which feature should be configured to allow the device to connect?
802.1X with EAP-MSCHAPv2
Downloadable ACL (dACL)
Web Authentication (WA)
MAC Authentication Bypass (MAB)
MAB allows non-802.1X devices to authenticate using their MAC address.
