Which TWO Microsoft Purview solutions should you use to protect sensitive data in Microsoft 365? (Choose two.)
Easy2A company wants to secure its Azure Kubernetes Service (AKS) cluster. They need to ensure that pods cannot communicate with each other unless explicitly allowed, and that secrets are encrypted at rest. Which TWO security controls should they implement?
Easy3Your company has a Microsoft 365 E5 subscription and uses Microsoft Defender for Office 365. You need to protect users from phishing attacks that use malicious links in email messages. The solution should allow users to report suspicious emails to the security team for analysis. You also want to automatically block repeated phishing attempts from the same sender. What should you configure?
Medium4Your company is deploying Microsoft Sentinel in a government agency that requires strict data residency. You need to ensure that all Sentinel data is stored within the United States. Which THREE actions must you take to meet this requirement?
Medium5Which THREE components are required to implement a Zero Trust network architecture using Microsoft Entra Internet Access (formerly Microsoft 365 Network Connectivity)?
Hard6Your company is designing a Zero Trust network for a hybrid workforce. Remote users connect via VPN to on-premises resources, while cloud apps use Microsoft Entra ID. You need to enforce conditional access based on device compliance and user risk. Which Microsoft security solution should you integrate with Entra ID to provide real-time device posture signals?
Hard7Your organization is implementing Microsoft Defender for Identity to protect on-premises Active Directory. Which THREE activities does Defender for Identity monitor?
Hard8Which TWO Azure policies should you assign to enforce secure configuration of Azure SQL Database? (Select two.)
Medium9Your organization is designing a hybrid identity infrastructure with Microsoft Entra ID. You need to ensure that users can access on-premises applications using passwordless authentication and that the solution minimizes latency for authentication requests. What should you implement?
Hard10Refer to the exhibit. The NSG is applied to a subnet containing Azure SQL databases. You notice that traffic from the internet to the databases is not being denied. What is the most likely reason?
Medium11Your company uses Azure Firewall to filter outbound traffic from a virtual network. You need to allow only HTTP and HTTPS traffic to specific FQDNs, while blocking all other outbound traffic. Which Azure Firewall rule type should you use?
Hard12You are designing a network security architecture for an Azure application that uses Azure Front Door and Azure Application Gateway. The application must be protected from DDoS attacks and common web exploits. Application traffic should be inspected by a web application firewall (WAF) before reaching the backend. What is the recommended deployment order?
