Question 81.

Which secure web gateway capability is most useful for enforcing different policies based on a user’s department?

  1. Identity-based policy
    2. Static routing
    3. Link aggregation
    4. DHCP relay

Correct Answer: 1

Explanation:

Identity-based policy allows the web security platform to make decisions using user and group information from an identity source such as Active Directory. This makes it possible to assign different policies to departments such as finance, engineering, human resources, or contractors. It is more precise than relying only on source IP addresses, especially where users move between devices or use dynamic addressing. Static routing, link aggregation, and DHCP relay provide network functions but do not supply organizational identity context for policy enforcement.

Question 82.

Which configuration is required when browsers must send traffic directly to a specific proxy rather than relying on transparent redirection?

  1. WCCP only
    2. Explicit proxy configuration
    3. HSRP configuration
    4. Spanning Tree configuration

Correct Answer: 2

Explanation:

Explicit proxy deployment requires the browser or operating system to know which proxy server should receive web requests. This can be configured manually, by policy, or through a PAC file. In this model, clients intentionally send traffic to the proxy rather than having it redirected transparently in the network. WCCP is commonly associated with transparent redirection. HSRP and Spanning Tree are networking technologies unrelated to client proxy selection.

Question 83.

Which mechanism can provide automatic proxy selection and basic failover between multiple proxy servers?

  1. ARP inspection
    2. DHCP snooping
    3. PAC file
    4. VLAN pruning

Correct Answer: 3

Explanation:

A PAC file can contain logic that selects one or more proxy servers based on the destination and can provide fallback behavior by specifying alternate proxies. This gives administrators flexibility in how browser traffic is directed. PAC logic can also permit direct access for specific approved destinations when necessary. ARP inspection, DHCP snooping, and VLAN pruning operate at different layers and do not control browser proxy selection.

Question 84.

Which protocol is designed to redirect selected web traffic transparently to a Cisco web proxy?

  1. OSPF
    2. BGP
    3. LACP
    4. WCCP

Correct Answer: 4

Explanation:

WCCP can redirect selected traffic from supported network devices to a Cisco Secure Web Appliance, allowing the proxy to inspect traffic without requiring explicit browser configuration. Depending on the design, it can also support redundancy and distribution across multiple appliances. OSPF and BGP provide routing, while LACP manages link aggregation. WCCP is therefore relevant when the objective is transparent web proxy redirection.

Question 85.

Which policy element is best suited to block an entire website category such as gambling?

  1. URL category policy
    2. Interface ACL only
    3. Route-map
    4. Port-channel policy

Correct Answer: 1

Explanation:

URL category policies allow administrators to make decisions based on how websites are classified. Categories such as gambling, social media, malware, streaming, or business can be allowed, blocked, or monitored according to organizational requirements. This is more scalable than maintaining large lists of individual domains manually. Interface ACLs and routing policies do not provide category-aware application-layer web filtering.

Question 86.

Which capability helps detect a malicious site that has been compromised even though it belongs to a normally permitted category?

  1. VLAN assignment
    2. Web reputation
    3. QoS marking
    4. Interface tracking

Correct Answer: 2

Explanation:

Web reputation evaluates the security risk associated with a destination separately from its content category. A business or news site may be categorized correctly but still have a poor reputation if it has been compromised or observed serving malicious content. Combining reputation with URL categorization improves decision quality. VLAN assignment, QoS, and interface tracking do not provide threat intelligence about web destinations.

Question 87.

Which control is best suited to prevent users from downloading specific risky file formats even if they are not currently identified as malware?

  1. DNS forwarding
    2. Route filtering
    3. File-type filtering
    4. Spanning Tree guard

Correct Answer: 3

Explanation:

File-type filtering allows administrators to block files based on format or content type, regardless of whether the file has a known malicious signature. Organizations may use this to block executables, scripts, macros, or archives from untrusted sources. This adds another security layer beyond reputation or antivirus scanning. DNS and routing controls operate at different layers and do not inspect the type of files being downloaded.

Question 88.

Which technology examines the behavior of suspicious code by running it in an isolated environment?

  1. DHCP relay
    2. HSRP
    3. URL categorization
    4. Sandbox analysis

Correct Answer: 4

Explanation:

Sandbox analysis executes suspicious files in an isolated environment and monitors behavior such as process creation, network connections, file changes, or persistence attempts. This helps identify threats that do not yet have known signatures. URL categorization evaluates websites rather than file behavior, while DHCP and HSRP are networking technologies. Sandboxing is particularly effective for detecting previously unknown malware.

Question 89.

Which capability can provide visibility when a previously unknown file is later determined to be malicious?

  1. Retrospective malware analysis
    2. HSRP state tracking
    3. Port mirroring only
    4. Route summarization

Correct Answer: 1

Explanation:

Retrospective malware analysis allows a security platform to update the verdict of files after they have already been observed. If new threat intelligence later identifies a file as malicious, defenders can investigate where the file was downloaded and which systems may have been affected. This is important because threat verdicts can change over time. Networking features such as HSRP and route summarization do not provide file-level retrospective visibility.

Question 90.

Which security policy can detect confidential data being sent to an unauthorized cloud storage service?

  1. VLAN pruning
    2. Data loss prevention
    3. OSPF filtering
    4. HSRP tracking

Correct Answer: 2

Explanation:

Data loss prevention policies inspect outbound traffic for sensitive information and can block or alert on unauthorized transfers. This can include personally identifiable information, financial records, intellectual property, or regulated data. DLP is especially useful when users have legitimate access to cloud services but should not upload sensitive information to unapproved destinations. Routing and Layer 2 functions do not inspect content for data sensitivity.

Question 91.

Which identity source is commonly used to map usernames to organizational groups for web policy enforcement?

  1. Active Directory
    2. ARP cache
    3. MAC address table
    4. Route table

Correct Answer: 1

Explanation:

Active Directory can provide user authentication and group membership information to the web security platform. This allows administrators to build policies around job roles, departments, or security groups rather than just network addresses. ARP and MAC tables provide device-related information but do not represent organizational identity. Route tables describe forwarding behavior and are not suitable for user policy decisions.

Question 92.

Which authentication approach is most suitable when domain users should be identified with minimal login prompts?

  1. Manual authentication for every connection
    2. Integrated authentication
    3. No authentication
    4. Source port identification

Correct Answer: 2

Explanation:

Integrated authentication can use the user’s existing domain credentials and session context to identify users without repeatedly prompting for credentials. This improves user experience while preserving detailed user-level logging and access control. Manual prompts are more disruptive, while anonymous access removes identity visibility. The exact method used depends on the environment, browser support, proxy deployment, and identity infrastructure.

Question 93.

Which feature is required to inspect encrypted HTTPS payloads for malware or prohibited content?

  1. TLS decryption
    2. Port security
    3. Route summarization
    4. VLAN tagging

Correct Answer: 1

Explanation:

HTTPS encrypts the application payload, so the secure web gateway must decrypt the session if it needs to inspect the actual content. TLS decryption allows the gateway to inspect files, URLs, and policy-relevant data before re-encrypting the traffic to the destination. This must be deployed carefully because of privacy, performance, and application compatibility concerns. Layer 2 and routing technologies do not provide visibility into encrypted web payloads.

Question 94.

Which condition can cause a mobile or desktop application to reject a TLS-inspected connection even when the inspection CA is trusted by the operating system?

  1. DHCP relay
    2. Certificate pinning
    3. Route redistribution
    4. DNS caching

Correct Answer: 2

Explanation:

Certificate pinning causes an application to expect a particular server certificate or public key rather than trusting any certificate issued by a trusted certificate authority. During TLS inspection, the proxy presents a dynamically generated certificate, which may fail the application’s pinning check. In such cases, a carefully scoped decryption bypass may be needed. DHCP, routing, and DNS caching do not explain this TLS compatibility issue.

Question 95.

Which approach is best when regulatory policy prohibits decrypting a specific class of sensitive web traffic?

  1. Create a narrowly scoped decryption exemption
    2. Disable web inspection globally
    3. Allow all HTTPS traffic without controls
    4. Remove user authentication

Correct Answer: 1

Explanation:

A narrowly scoped decryption exemption preserves end-to-end encryption only for traffic that should not be inspected while maintaining security visibility elsewhere. This is a better balance than disabling TLS inspection globally. The exception should be based on documented requirements, limited to the smallest practical scope, and reviewed periodically. Other controls such as reputation and DNS-layer security may continue to provide protection even when payload decryption is not performed.

Question 96.

Which information in a Secure Web Appliance log most directly explains why access to a specific URL was blocked?

  1. Fan speed
    2. Interface temperature
    3. Switch serial number
    4. Matched policy and enforcement action

Correct Answer: 4

Explanation:

The matched policy and resulting enforcement action provide the clearest explanation for why a request was blocked. Additional fields such as username, URL, category, reputation, timestamp, and malware verdict can provide context. Hardware telemetry does not explain web policy decisions. Detailed web access logs are therefore one of the most important troubleshooting sources when investigating blocked business applications or suspicious browsing activity.

Question 97.

Which Cisco service can protect roaming users at the DNS layer when they are outside the corporate network?

  1. Cisco Umbrella
    2. Cisco UCS Manager
    3. Cisco APIC
    4. Cisco Prime Infrastructure

Correct Answer: 1

Explanation:

Cisco Umbrella can provide DNS-layer security for roaming users by directing DNS requests through its cloud security service using supported endpoint integration. This allows policy enforcement to continue when users are working from home, traveling, or connected to public networks. The service can block malicious or prohibited domains before the full connection is established. UCS Manager and APIC are infrastructure management platforms, while Prime Infrastructure is focused on network management.

Question 98.

Which advantage is provided by blocking a malicious domain at the DNS layer?

  1. It automatically removes malware from the endpoint
    2. It can prevent the subsequent connection before an application session is established
    3. It decrypts all encrypted traffic
    4. It replaces all endpoint protection products

Correct Answer: 2

Explanation:

DNS-layer blocking interrupts the connection process at an early stage by preventing a malicious domain from resolving to its intended destination address. This can stop phishing, malware downloads, or command-and-control communication before a full application session begins. It does not remove malware from the endpoint or replace endpoint security. DNS security is one layer within a broader defense strategy that also includes endpoint, web, identity, and network controls.

Question 99.

Which deployment method is best when a new secure web policy may affect many business applications and users?

  1. Apply it to a pilot group first
    2. Deploy globally without validation
    3. Disable access logging
    4. Delete the previous configuration immediately

Correct Answer: 1

Explanation:

A pilot deployment allows administrators to observe real-world behavior on a small, representative set of users before expanding the policy. This helps identify false positives, authentication issues, certificate problems, and application compatibility concerns while limiting disruption. Logging should remain enabled so outcomes can be measured accurately. Large-scale changes to proxy or decryption policy should generally be staged rather than applied globally without testing.

Question 100.

After TLS inspection is enabled, one approved business application stops connecting while other websites work normally. What is the best troubleshooting response?

  1. Disable the entire Secure Web Appliance
    2. Remove DNS security
    3. Investigate certificate validation and application-specific TLS behavior, then create only the required exception
    4. Block all HTTPS traffic

Correct Answer: 3

Explanation:

When only one application fails after TLS inspection is enabled, the issue is likely application-specific rather than a general proxy failure. The security team should review TLS logs, certificate trust, supported protocol versions, and possible certificate pinning. If the application cannot operate through inspection, the narrowest justified bypass should be created. This preserves inspection for other traffic while restoring the required application. Broadly disabling web security or HTTPS would unnecessarily weaken protection.
