Quick Answer
The correct action is to add the Office 365 IP ranges and FQDNs to the allowed list. This is because Azure NSGs operate at Layer 3/4, filtering traffic based on source/destination IP, port, and protocol; since Office 365 uses TLS over TCP/443, the administrator must explicitly permit the published IP ranges and fully qualified domain names (FQDNs) that Microsoft provides for its SaaS services. On the Cisco SCOR 350-701 exam, this scenario tests your understanding of cloud security group policies and the principle of least privilege—specifically, how to maintain a deny-all-outbound posture while enabling necessary SaaS connectivity without resorting to overly permissive rules. A common trap is assuming you can allow all outbound HTTPS traffic, but the correct approach is to restrict to Office 365’s specific endpoints. Memory tip: think “O365 FQDNs over 443” to recall that TLS traffic to SaaS requires granular allow-listing, not a blanket HTTPS rule.
This 350-701 practice question tests your understanding of cloud security. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
During a cloud migration, an administrator notices that a workload in Azure is generating outbound traffic that is being blocked by the cloud security group. The workload requires connectivity to a specific SaaS application (Office 365) using TLS. The security group denies all outbound traffic except to specific IP ranges. Which action should the administrator take?
Implement a proxy server
Why wrong: Adds complexity, not necessary.
Use Azure Private Link
Why wrong: For private connectivity to Azure services, not third-party SaaS.
Add the Office 365 IP ranges and FQDNs to the allowed list
Allows required traffic while maintaining security.
Disable the security group temporarily
Why wrong: Insecure and temporary.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Add the Office 365 IP ranges and FQDNs to the allowed list
Option C is correct because the administrator needs to allow outbound traffic to Office 365, which uses TLS over TCP/443. Since the security group denies all outbound traffic except to specific IP ranges, the most direct and secure method is to add the published Office 365 IP ranges and FQDNs to the allowed list. This ensures the workload can reach the SaaS application without bypassing security controls or introducing additional latency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates often confuse Azure Private Link (which is for private connectivity to Azure services) with general SaaS connectivity, or they incorrectly assume a proxy server is always required for outbound traffic control, when in fact the simplest solution is to update the security group rules with the correct IP ranges and FQDNs.
Detailed technical explanation
Office 365 publishes its IP ranges and FQDNs in a weekly JSON file (available via the Office 365 IP Address and URL web service) that includes specific TCP/443 endpoints for Exchange Online, SharePoint Online, and Skype for Business. Azure Network Security Groups (NSGs) can filter outbound traffic by destination IP address or fully qualified domain names (FQDNs) using Azure Firewall or NSG application rules, but NSGs alone do not support FQDN-based outbound rules; for FQDN filtering, Azure Firewall or a third-party NVA is required. In a real-world scenario, the administrator must ensure the allowed list is updated regularly to avoid service disruption as Microsoft changes its IP ranges.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the 350-701 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
