Question No 1:

What causes authentication failures on a Cisco WSA when LDAP is used for authentication?

A. when the passphrase contains only 5 characters
B. when the passphrase contains characters that are not 7-bit ASCII
C. when the passphrase contains one of the following characters "˜@ # $ % ^"™
D. when the passphrase contains 50 characters

Answer: B

Explanation:

When configuring LDAP authentication on a Cisco Web Security Appliance (WSA), the system relies on LDAP to validate users. For this authentication to work correctly, the credentials (specifically the passphrase) must meet certain requirements and standards.

Let’s analyze each option in detail:

Option A – When the passphrase contains only 5 characters:
There is no specific restriction on the length of the passphrase in general, as long as it meets the LDAP directory's password policy (such as the minimum length). A 5-character passphrase can be valid if the LDAP system allows it. Therefore, A is not likely to be the cause of authentication failures.

Option B – When the passphrase contains characters that are not 7-bit ASCII:
This is the correct answer. LDAP servers typically expect ASCII characters for usernames and passphrases. If the passphrase contains non-7-bit ASCII characters (such as extended Unicode or special characters outside the standard ASCII character set), the Cisco WSA might not correctly process the passphrase, resulting in authentication failures. Therefore, B is the most common cause of such issues.

Option C – When the passphrase contains one of the following characters "˜@ # $ % ^"™:
Certain special characters, like @, #, $, %, ^, and others, may be problematic if they are not handled correctly by the LDAP system, but these are not typically the direct cause of failure unless the LDAP server itself has restrictions or specific configurations about special characters. However, the presence of such characters in the passphrase is unlikely to be a universal issue causing failure across all systems. Therefore, C is not the most common cause of failure.

Option D – When the passphrase contains 50 characters:
The length of the passphrase is generally not a direct cause of authentication failure unless it exceeds the limits set by the LDAP directory. Most LDAP systems allow passphrases of more than 50 characters. As long as the passphrase meets the server's configuration and is properly encoded, D is unlikely to be the issue.

In summary, the most likely cause of authentication failures when LDAP is used on a Cisco WSA is B – when the passphrase contains characters that are not 7-bit ASCII, as LDAP typically expects only standard ASCII characters in the credentials.

Question No 2:

Based on the provided exhibit, which statement about the transaction log is true?

A The log does not have a date and time.
B The proxy had the content and did not contact other servers.
C The transaction used TCP destination port 8187.
D The AnalyzeSuspectTraffic policy group was applied to the transaction.

Correct Answer: B

Explanation:

In analyzing network transaction logs, certain key pieces of information help identify the nature of the transaction and the system's behavior. Let’s break down the options:

A The log does not have a date and time: Transaction logs typically include a date and time for tracking when the event occurred. If the exhibit shows that there is no date or time, this statement would be correct. However, this is not typically the case in standard logs, as timestamps are critical for tracking events. If the log does include date and time, A would be incorrect.
B The proxy had the content and did not contact other servers: In many proxy server configurations, content may be cached locally to enhance performance. This means the proxy might serve the content directly from its cache without needing to contact other servers. If the log indicates that the content was served by the proxy without contacting external servers, then this statement is likely true. This is a common scenario for proxy servers functioning in caching mode.
C The transaction used TCP destination port 8187: This statement would be correct if the log clearly shows that TCP port 8187 was used as the destination port for the transaction. While 8187 is not a commonly used port, it could be specific to the application or service in question. However, without seeing the actual log data, it's difficult to confirm this option definitively.
D The AnalyzeSuspectTraffic policy group was applied to the transaction: If the log indicates that a policy group like AnalyzeSuspectTraffic was applied to the transaction, then D would be accurate. This could be part of a security system designed to flag and analyze suspicious traffic. However, if no such policy is mentioned in the log, this option would be incorrect.

Based on the information provided and typical use cases, B is the most likely correct answer. If the proxy served content from its local cache without contacting external servers, this would be consistent with how many proxy systems operate in a caching mode. Therefore, the answer is B.

Question No 3:

Which two features can be used with an upstream and downstream Cisco WSA web proxy to have the upstream WSA identify users by their client IP address? (Choose two.)

A. X-Forwarded-For
B. high availability
C. web cache
D. via
E. IP spoofing

Answer: A, D

Explanation:

To enable the upstream Cisco Web Security Appliance (WSA) to identify users by their client IP address in an upstream-downstream proxy configuration, certain features and configurations can help forward the client’s real IP address through the proxies. The two correct answers in this case are A. X-Forwarded-For and D. via, both of which are used to pass the original client IP address along to the upstream WSA.

Here’s why:

A. X-Forwarded-For: This is a common HTTP header used to pass the original client IP address through proxies and load balancers. The X-Forwarded-For header allows the upstream WSA to receive the correct client IP address, even if the request has passed through an intermediary proxy (downstream WSA). The X-Forwarded-For header contains a comma-separated list of IP addresses, where the first IP in the list is typically the original client IP. This is a crucial feature for identifying the true client IP in proxy environments.
B. High availability: High availability refers to the system’s ability to remain operational and accessible by using multiple redundant systems. While high availability can be a key factor in maintaining uptime for the Cisco WSA, it does not directly relate to the ability of the upstream WSA to identify the client IP address. This feature is about ensuring that service remains uninterrupted rather than passing client IP addresses.
C. Web cache: A web cache is used to store previously retrieved data to speed up access to frequently requested content. While caching can improve performance, it does not relate to identifying or passing the client’s IP address. Web caching has no impact on the passing of the client IP address from downstream to upstream proxies.
D. Via: The Via HTTP header is used to track intermediate proxies and gateways that a request passes through. It can also carry the client’s original IP address in some configurations. Like the X-Forwarded-For header, the Via header helps the upstream WSA identify the original client IP by including information about the proxies that processed the request. The Via header can be configured to pass this information.
E. IP spoofing: IP spoofing refers to falsifying the IP address of the source of a network packet. While spoofing could potentially mask the real client IP address, it is not a feature that helps the upstream WSA identify the client’s true IP address. In fact, IP spoofing undermines accurate IP identification and can create security concerns.

In summary, to enable the upstream WSA to correctly identify users by their client IP address, A. X-Forwarded-For and D. Via are the features that should be used. These headers are designed to pass along the original client IP address through proxies.

Therefore, the correct answers are A and D.

Question No 4:

Which two configuration options are available on a Cisco WSA within a decryption policy? (Choose two.)

A Pass Through
B Warn
C Decrypt
D Allow
E Block

Correct answer: C and A

Explanation:

Cisco Web Security Appliance (WSA) is designed to secure web traffic by providing various decryption policies that control how encrypted traffic (like HTTPS) is handled. Decryption policies allow the Cisco WSA to inspect and apply security measures to encrypted traffic.

In the context of decryption policies, the options available control how encrypted traffic is processed and whether it should be decrypted for inspection or left unaltered. Let's go through the options:

A Pass Through: This option allows traffic to pass without being decrypted. Essentially, the traffic is allowed to continue without inspection, keeping the encryption intact. This is useful in situations where you may not want to decrypt the traffic for privacy or performance reasons. This is a valid configuration option.

B Warn: The Warn option is not typically part of the decryption policy in Cisco WSA. Warnings are more often used in the context of logging or alerting users about issues or configuration settings, but not directly related to decryption actions.

C Decrypt: This is the correct and key option in the decryption policy. It instructs the Cisco WSA to decrypt the encrypted traffic (like HTTPS traffic) for inspection. Decrypting the traffic allows the WSA to apply security policies, scan for threats, and enforce security measures on the contents of the traffic.

D Allow: The Allow option is generally used in access control and traffic filtering, but it's not specifically part of the decryption policy. It's more of a general action used in firewall or access rules, not in the context of decryption.

E Block: Like Allow, Block is typically used in access control and traffic filtering, but it is not a direct option in the decryption policy for HTTPS traffic on the Cisco WSA.

Therefore, the correct answers are C (Decrypt) and A (Pass Through), as they represent the actions you can configure in a Cisco WSA decryption policy for handling encrypted traffic.

Question No 5:

Which information in the HTTP request is used to determine if it is subject to the referrer exceptions feature in the Cisco WSA?

A protocol
B version
C header
D payload

Correct Answer: C

Explanation:

The referrer exceptions feature in the Cisco Web Security Appliance (WSA) is used to determine how to handle HTTP requests based on the referrer header. The referrer header is part of the HTTP request and indicates the address of the previous web page from which a link to the currently requested page was followed. Referrer exceptions are primarily used to configure which URLs are allowed or blocked based on the content of this referrer header.

Here’s a breakdown of the options:

A. Protocol:
The protocol (such as HTTP or HTTPS) is part of the URL, but it is not used directly to determine if a request is subject to referrer exceptions in the Cisco WSA. The protocol is more related to how the communication between the client and the server occurs, rather than the specific content or behavior of the request.
B. Version:
The version refers to the HTTP version being used, such as HTTP/1.1 or HTTP/2. While this is part of the HTTP request, it does not play a role in determining if the request is subject to referrer exceptions.
C. Header:
The referrer header in the HTTP request is used to determine if the request matches any configured referrer exceptions in the Cisco WSA. The WSA can inspect the referrer header and apply specific policies based on the URLs contained in that header.
D. Payload:
The payload refers to the body of the HTTP request, which typically contains data being sent to the server, such as form submissions or file uploads. While the payload can be important for other types of security inspection, it is not used for determining referrer exceptions.

The referrer exceptions feature relies on inspecting the header of the HTTP request, specifically the referrer header, to determine if special handling rules should be applied. Therefore, the correct answer is C.

Question No 6:

What is used to configure WSA as an explicit proxy?

A. IP Spoofing from router
B. Network settings from user browser
C. WCCP redirection from firewall
D. Auto redirection using PBR from switch

Answer: B

Explanation:

A Web Security Appliance (WSA), when configured as an explicit proxy, requires clients to be configured to send their web traffic to the proxy server explicitly. This configuration is typically done by setting the network settings in the user's browser or device. The browser needs to be set to point to the WSA as the proxy server for web traffic (HTTP/HTTPS). This is known as an explicit proxy configuration because the client explicitly knows where to send its web traffic.

Here's why the other options are not correct:

A. IP Spoofing from router: IP spoofing refers to altering the source IP address of packets to disguise the true source. This is not a method for configuring a proxy, especially an explicit proxy. IP spoofing can lead to security risks and is unrelated to the configuration of proxies like WSA.
C. WCCP redirection from firewall: WCCP (Web Cache Communication Protocol) is used for transparent proxying, not explicit proxying. In WCCP, traffic is redirected to the proxy without requiring explicit configuration on the client side (i.e., the browser does not need to be aware of the proxy). WCCP is generally used in a transparent proxy setup, not when the WSA is configured as an explicit proxy.
D. Auto redirection using PBR from switch: PBR (Policy-Based Routing) allows for traffic redirection based on policies but is typically used in transparent proxy configurations or for other routing purposes. It is not specifically related to explicit proxy configuration. Explicit proxies require client-side configuration, not network-based redirection.

The correct method for configuring a WSA as an explicit proxy is to adjust the network settings from the user browser so that all web traffic is sent directly to the proxy server. This configuration tells the browser to use the proxy for its web traffic. Therefore, the correct answer is B.

Question No 7:

Which key is needed to pair a Cisco WSA and Cisco ScanCenter for CTA?

A public SSH key that the Cisco WSA generates
B public SSH key that Cisco ScanCenter generates
C private SSH key that Cisco ScanCenter generates
D private SSH key that the Cisco WSA generates

Answer: A

Explanation:

When pairing a Cisco Web Security Appliance (WSA) and Cisco ScanCenter for Content Transformation and Analysis (CTA), a secure method of authentication is required to ensure communication between the two devices. This is typically achieved through SSH key-based authentication, which involves generating a pair of keys (a private key and a public key). The correct key used for pairing depends on the role of the device in the communication process.

Here’s why Option A is the correct answer:

Option A: Public SSH key that the Cisco WSA generates

In the process of pairing the Cisco WSA with Cisco ScanCenter, the Cisco WSA generates a public SSH key that is shared with Cisco ScanCenter. The WSA’s public key is used to establish a secure connection, ensuring that the ScanCenter can authenticate the WSA when it attempts to connect. The public key is meant to be shared freely, while the private key is kept secret. The ScanCenter will use the WSA's public key for verification.

Option B: Public SSH key that Cisco ScanCenter generates

While Cisco ScanCenter generates a key pair, it is not the public key from the ScanCenter that is shared with the WSA for the pairing process. Instead, it is the WSA's public key that is used by ScanCenter to authenticate the WSA.

Option C: Private SSH key that Cisco ScanCenter generates

The private key is kept secret and used for decryption and authentication purposes. It is not shared in the pairing process between the WSA and Cisco ScanCenter. The private key should remain on the device that generated it, and it is used to prove the device's identity when responding to requests. Therefore, the private key is not used directly for the pairing process.

Option D: Private SSH key that the Cisco WSA generates

As with the private key from Cisco ScanCenter, the private SSH key generated by the Cisco WSA is not shared with the ScanCenter. The private key is used internally on the device to prove its identity when responding to authentication requests but is not shared with the other device for pairing.

In summary, to establish a secure connection between the Cisco WSA and Cisco ScanCenter for CTA, the WSA's public SSH key is required by the ScanCenter to authenticate the WSA. Therefore, the correct answer is A.

Question No 8:

What is a benefit of integrating Cisco Cognitive Threat Analytics with a Cisco WSA?

A It adds additional information to the Cisco WSA reports
B It adds additional malware protection to the Cisco WSA
C It provides the ability to use artificial intelligence to block viruses
D It reduces time to identify threats in the network

Answer: D

Explanation:

Cisco Cognitive Threat Analytics (CTA) is an advanced security solution that leverages machine learning and artificial intelligence (AI) to detect, analyze, and respond to potential threats in real-time. When integrated with Cisco Web Security Appliance (WSA), the primary benefit is that it enhances the speed at which threats are identified and mitigated within a network.

Here’s why D (It reduces time to identify threats in the network) is the best answer:

Cisco Cognitive Threat Analytics uses machine learning algorithms to analyze network traffic and detect threats faster than traditional methods. It can recognize patterns of suspicious activity, providing quick detection of new and emerging threats, which drastically reduces the time it takes to identify potential security issues.

Let’s explore the other options to see why they are not the most accurate:

A. It adds additional information to the Cisco WSA reports: While CTA does enhance the data available to administrators, this is not the most significant benefit. The primary advantage lies in quicker threat detection and analysis, not just enriching the reports.
B. It adds additional malware protection to the Cisco WSA: While CTA enhances the security features of Cisco WSA, particularly by identifying threats based on behavior rather than known signatures, its main role is to improve the speed of threat identification, not just to add extra layers of malware protection. Cisco WSA already provides malware protection, but CTA boosts the response time and effectiveness.
C. It provides the ability to use artificial intelligence to block viruses: Cisco CTA uses AI to analyze network traffic for suspicious patterns and behaviors. While it uses AI, it’s not primarily about blocking viruses but identifying and reacting to suspicious activities, which helps in threat identification and response time rather than blocking specific viruses.

In conclusion, D is the correct answer because integrating Cisco Cognitive Threat Analytics with a Cisco WSA primarily improves threat detection time, which is the core benefit of leveraging advanced analytics and AI technologies in the context of network security.
