350-701 Content Security — 10 Questions

Question 1

A company uses Cisco Umbrella to enforce web security. After deploying a new policy that blocks all social media sites, users report that they cannot access a corporate Salesforce instance that uses a social login feature. Which Umbrella setting should be adjusted to resolve the issue without weakening the policy?

Accepted Answer

Add Salesforce to the Application Settings allowed list. Option D is correct because the social login feature for Salesforce is being blocked by the Social Networking content category in Cisco Umbrella. By adding Salesforce to the Application Settings allowed list, you permit the specific application traffic while keeping the broader social media policy intact. This granular control ensures that only the required Salesforce instance bypasses the block, without weakening the overall security posture.

Answer

Create a bypass code for users to access Salesforce

Answer

Disable the Social Networking category under Content Categories

Answer

Configure Intelligent Proxy to inspect Salesforce traffic

Question 2

An engineer is troubleshooting a Cisco WSA that is failing to block malware downloads from a specific cloud storage website. The URL filtering policy is set to block the 'Cloud Storage' category, and the Web Reputation score is set to block scores below -5.0. Users can still download files. What is the most likely cause?

Accepted Answer

The file type is not configured for malware inspection. The Cisco WSA can block malware downloads only if it inspects the file content. If the file type is not configured for malware inspection, the WSA will allow the download even if the URL category and reputation score are set to block. This is because malware inspection requires explicit configuration of file types (e.g., .exe, .zip) to scan for threats, and without it, the WSA bypasses deep content analysis.

Answer

HTTPS proxy decryption is not configured

Answer

The L4 Traffic Monitor is not enabled

Answer

The users are not authenticated

Question 3

A network administrator wants to block access to a specific URL category on the Cisco WSA but allow access to all other categories. Which action should be taken in the Access Policy?

Accepted Answer

Set the action to 'Block' for the category. To block access to a specific URL category while allowing all others, the Access Policy must set the action for that category to 'Block'. The Cisco WSA evaluates URL categories in order of precedence, and a 'Block' action explicitly denies HTTP/HTTPS requests matching that category, while all other categories default to 'Allow' unless otherwise configured.

Answer

Set the action to 'Monitor' for the category

Answer

Set the action to 'Redirect' for the category

Answer

Set the action to 'Warn' for the category

Question 4

An organization is using Cisco ESA to protect against email-borne threats. They notice that some phishing emails are not being caught by the anti-spam engine. The emails contain malicious URLs that are rewritten by the ESA. Which feature should be verified to ensure the rewritten URLs are properly analyzed?

Accepted Answer

URL filtering and analysis settings. B is correct because the URL filtering and analysis settings control how the Cisco ESA rewrites and subsequently analyzes malicious URLs. When a phishing email contains a malicious URL, the ESA can rewrite the URL to point to its own proxy for real-time analysis. If this feature is not properly configured or if the analysis settings (such as reputation scoring or time-of-click verification) are disabled, the rewritten URLs may not be inspected, allowing the threat to bypass detection.

Answer

Data Loss Prevention (DLP) policies

Answer

Anti-Virus scanning engine

Answer

Encryption policies

Question 5

A company is deploying Cisco Umbrella to enforce security policies for remote users. They want to ensure that DNS requests from roaming clients are routed through Umbrella's DNS resolvers. However, some users are bypassing Umbrella by using third-party DNS servers like Google (8.8.8.8). Which configuration should be applied to prevent this?

Accepted Answer

Enable DNS Policy in the Umbrella roaming client. Option D is correct because the Umbrella roaming client's DNS Policy feature forces all DNS traffic from the endpoint to use Umbrella's DNS resolvers, even if the user manually configures a third-party DNS server like Google (8.8.8.8). This is achieved by intercepting DNS requests at the OS level and redirecting them to the Umbrella resolvers, effectively preventing bypass attempts without relying on network-level blocks.

Answer

Configure Content Filtering to block Google DNS

Answer

Add a firewall rule on each client to block port 53 to all but Umbrella

Answer

Enable IP Layer Enforcement in the Umbrella dashboard

Question 6

A network administrator needs to configure Cisco WSA to decrypt HTTPS traffic for inspection. What is the first step that must be completed?

Accepted Answer

Install a Certificate Authority (CA) certificate on the WSA and distribute it to clients. The first step in configuring Cisco WSA for HTTPS decryption is to install a Certificate Authority (CA) certificate on the WSA and distribute it to client devices. This establishes trust because the WSA acts as a man-in-the-middle, generating a new certificate for each HTTPS session signed by this CA; without the CA certificate in the clients' trusted root store, browsers will display certificate warnings and block the connection.

Answer

Create a bypass list for internal sites

Answer

Configure an Access Control List (ACL) to allow decryption

Answer

Configure user authentication

Question 7

An organization is using Cisco ESA and wants to ensure that outgoing emails containing credit card numbers are blocked before leaving the network. Which feature should be configured?

Accepted Answer

Data Loss Prevention (DLP) policies. Cisco ESA uses Data Loss Prevention (DLP) policies to inspect outgoing email content for sensitive data such as credit card numbers. DLP can identify patterns (e.g., 16-digit card numbers) using predefined or custom dictionaries and enforce actions like blocking, quarantining, or encrypting the message before it leaves the network. Anti-Spam, Encryption, and Anti-Virus policies do not perform content-based pattern matching for sensitive data.

Answer

Anti-Spam policies

Answer

Encryption policies

Answer

Anti-Virus scanning

Question 8

During a security audit, it is discovered that some malware downloads were not blocked by the Cisco WSA even though the Web Reputation score was set to block scores below -5.0. The logs show that the downloads came from sites with a reputation score of -6.2. What is the most likely reason the downloads were not blocked?

Accepted Answer

The file type was not configured for malware inspection. The Cisco WSA uses Web Reputation filtering to block traffic based on reputation scores, but this filtering operates at the URL or domain level, not at the file content level. Even if a site has a very low reputation score (e.g., -6.2), the WSA will only block the download if the file type is included in the malware inspection configuration. If the file type (e.g., .exe, .zip) is not configured for malware inspection, the WSA will allow the download despite the low reputation score, because reputation-based blocking alone does not inspect the content of the file.

Answer

HTTPS decryption was not enabled

Answer

The users were not authenticated

Answer

The Web Reputation threshold was not applied correctly

Question 9

Which TWO actions are best practices when configuring a Cisco WSA to block malicious websites? (Choose two.)

Accepted Answer

Configure URL filtering categories to block known malicious categories. Option A is correct because Cisco WSA URL filtering categories allow administrators to block entire groups of known malicious sites, such as malware, phishing, or spyware categories, which are pre-classified by Cisco Talos. This provides a broad, proactive defense against threats without needing to maintain individual URL block lists. Option E is correct because Web Reputation filtering uses a scoring system (1–10, with lower scores being more malicious) to dynamically block or warn users about websites with poor reputation, even if they are not in a specific malicious category, adding a layer of behavioral analysis.

Answer

Set the default action to 'Monitor' for all categories

Answer

Disable user authentication to simplify policy

Answer

Allow all HTTPS traffic to improve performance

Question 10

Which THREE features are available in Cisco Umbrella to protect against DNS-based threats? (Choose three.)

Accepted Answer

IP-layer enforcement. Cisco Umbrella provides DNS-layer security (option C) as its core function, intercepting DNS queries to block requests to malicious domains before a connection is established. IP-layer enforcement (option A) extends protection by applying policies based on the destination IP address, blocking traffic to known malicious IPs even if DNS resolution is bypassed. Application control (option B) allows administrators to permit or block specific cloud applications (e.g., Dropbox, Facebook) at the DNS level, preventing data exfiltration or unauthorized usage through DNS-based application identification.

Answer

Data Loss Prevention (DLP)

Answer

Anti-virus scanning
