• Question 31:

  You are designing a new Azure environment based on the security best practices of the Microsoft Cloud Adoption Framework for Azure. The environment will contain one subscription for shared infrastructure components and three separate subscriptions for applications.

  You need to recommend a deployment solution that includes network security groups (NSGs), Azure Firewall, Azure Key Vault, and Azure Bastion. The solution must minimize deployment effort and follow security best practices of the Microsoft Cloud Adoption Framework for Azure.

  What should you include in the recommendation?

  A. the Azure landing zone accelerator

  B. the Azure Well-Architected Framework

  C. Azure Security Benchmark v3

  D. Azure Advisor

  Correct Answer: A

  Explanation:

  About Azure Bastion host and jumpboxes

  The most simple solution is to host a jumpbox on the virtual network of the data management landing zone or data landing zone to connect to the data services through private endpoints.

  Azure Bastion provides a few other core security benefits, including:

  *

  The service integrates with native security appliances for an Azure virtual network, such as Azure Firewall.

  Note:

  *

  Platform landing zones: Subscriptions deployed to provide centralized services, often operated by a central team, or a number of central teams split by function (e.g. networking, identity), which will be used by various workloads and applications. Platform landing zones represent key services that often benefit from being consolidated for efficiency and ease of operations. Examples include networking, identity, and management services.

  *

  The Azure App Service landing zone accelerator is an open-source collection of architectural guidance and reference implementation to accelerate deployment of Azure App Service at scale. It can provide a specific architectural approach and reference implementation via infrastructure as code templates to prepare your landing zones. The landing zones adhere to the architecture and best practices of the Cloud Adoption Framework.

  Incorrect:

  Not B: The Azure Well-Architected Framework is a set of guiding tenets that can be used to improve the quality of a workload. The framework consists of five pillars of architectural excellence:

  Reliability Security Cost Optimization Operational Excellence Performance Efficiency

  Not C: The Azure Security Benchmark (ASB) provides prescriptive best practices and recommendations to help improve the security of workloads, data, and services on Azure. This benchmark is part of a set of holistic security guidance that also includes:

  *

  Cloud Adoption Framework: Guidance on security, including strategy, roles and responsibilities, Azure Top 10 Security Best Practices, and reference implementation.

  *

  Azure Well-Architected Framework: Guidance on securing your workloads on Azure.

  *

  Microsoft Security Best Practices: Recommendations with examples on Azure.

  Microsoft Cybersecurity Reference Architectures (MCRA): Visual diagrams and guidance for security components and relationships

  *

  The Azure Security Benchmark focuses on cloud-centric control areas. These controls are consistent with well-known security benchmarks, such as those described by the Center for Internet Security (CIS) Controls, National Institute of

  Standards and Technology (NIST), and Payment Card Industry Data Security Standard (PCI-DSS).

• Question 37:

  You have an Azure subscription.

  Your company has a governance requirement that resources must be created in the West Europe or North Europe Azure regions.

  What should you recommend using to enforce the governance requirement?

  A. Azure management groups

  B. custom Azure roles

  C. Azure Policy assignments

  D. regulatory compliance standards in Microsoft Defender for Cloud

  Correct Answer: C

  Explanation:

  Azure Policy helps to enforce organizational standards and to assess compliance at-scale.

  Common use cases for Azure Policy include implementing governance for resource consistency, regulatory compliance, security, cost, and management. Policy definitions for these common use cases are already available in your Azure

  environment as built-ins to help you get started.

  Specifically, some useful governance actions you can enforce with Azure Policy include:

  Ensuring your team deploys Azure resources only to allowed regions

  Enforcing the consistent application of taxonomic tags

  Requiring resources to send diagnostic logs to a Log Analytics workspace

  Note: Once your business rules have been formed, the policy definition or initiative is assigned to any scope of resources that Azure supports, such as management groups, subscriptions, resource groups, or individual resources. The

  assignment applies to all resources within the Resource Manager scope of that assignment.

• Question 38:

  You design cloud-based software as a service (SaaS) solutions.

  You need to recommend a recovery solution for ransomware attacks. The solution must follow Microsoft Security Best Practices.

  What should you recommend doing first?

  A. Develop a privileged identity strategy.

  B. Implement data protection.

  C. Develop a privileged access strategy.

  D. Prepare a recovery plan.

  Correct Answer: D

  Recommend a ransomware strategy by using Microsoft Security Best Practices The three important phases of ransomware protection are:

  *

  create a recovery plan

  *

  limit the scope of damage

  *

  harden key infrastructure elements

  Plan for ransomware protection and extortion-based attacks Phase 1 of ransomware protection is to develop a recovery plan. The first thing you should do for these attacks is prepare your organization so that it has a viable alternative to paying the ransom. While attackers in control of your organization have a variety of ways to pressure you into paying, the demands

  primarily focus on two categories:

  Pay to regain access

  Pay to avoid disclosure

• Question 39:

  You use Azure Pipelines with Azure Repos to implement continuous integration and continuous deployment (CI/CD) workflows for the deployment of applications to Azure.

  You need to recommend what to include in dynamic application security testing (DAST) based on the principles of the Microsoft Cloud Adoption Framework for Azure.

  What should you recommend?

  A. unit testing

  B. penetration testing

  C. dependency checks

  D. threat modeling

  Correct Answer: B

  Dynamic application security testing (DAST)

  In a classical waterfall development model, security was typically introduced at the last step, right before going to production. One of the most popular security approaches is penetration testing or pen testing. Penetration testing lets a team

  look at the application from a black-box security perspective, as in, closest to an attacker mindset.

• Question 40:

  You have a Microsoft 365 subscription.

  You are designing a user access solution that follows the Zero Trust principles of the Microsoft Cybersecurity Reference Architectures (MCRA).

  You need to recommend a solution that automatically restricts access to Microsoft Exchange Online, SharePoint Online, and Teams in near-real-time (NRT) in response to the following Azure AD events:

  1.

  A user account is disabled or deleted.

  2.

  The password of a user is changed or reset.

  3.

  All the refresh tokens for a user are revoked.

  4.

  Multi-factor authentication (MFA) is enabled for a user.

  Which two features should you include in the recommendation? Each correct answer presents part of the solution.

  NOTE: Each correct selection is worth one point.

  A. continuous access evaluation

  B. Azure AD Application Proxy

  C. a sign-in risk policy

  D. Azure AD Privileged Identity Management (PIM)

  E. Conditional Access

  Correct Answer: AE

  Continuous access evaluation

  Key benefits

  User termination or password change/reset: User session revocation will be enforced in near real time.

  Network location change: Conditional Access location policies will be enforced in near real time.

  Token export to a machine outside of a trusted network can be prevented with Conditional Access location policies.

  Scenarios

  There are two scenarios that make up continuous access evaluation, critical event evaluation and Conditional Access policy evaluation.

  *

  Critical event evaluation Continuous access evaluation is implemented by enabling services, like Exchange Online, SharePoint Online, and Teams, to subscribe to critical Azure AD events. Those events can then be evaluated and enforced near real time. Critical event evaluation doesn't rely on Conditional Access policies so it's available in any tenant. The following events are currently evaluated:

  User Account is deleted or disabled Password for a user is changed or reset Multi-factor authentication is enabled for the user Administrator explicitly revokes all refresh tokens for a user High user risk detected by Azure AD Identity Protection

  *

  Conditional Access policy evaluation

  Exchange Online, SharePoint Online, Teams, and MS Graph can synchronize key Conditional Access policies for evaluation within the service itself.

  This process enables the scenario where users lose access to organizational files, email, calendar, or tasks from Microsoft 365 client apps or SharePoint Online immediately after network location changes.
