AZ-800 - Microsoft Azure Networking Solutions Azure Firewall Policies Questions and Answers — Questions and Answers
Question 1: An organization wants to enforce a mandatory set of corporate security rules on all Azure Firewalls while allowing individual application teams to add their own specific rules. The corporate rules must always be processed before the application-specific rules. Which Azure Firewall Policy configuration should be used?
- Create a single, global Firewall Policy and grant all teams contributor access.
- Create a parent Firewall Policy for corporate rules and child policies for each application team that inherit from the parent. (Correct answer)
- Use classic firewall rules on each firewall and use Azure Policy to audit for compliance.
- Create separate, independent Firewall Policies for corporate rules and for each application team.
Correct answer: Create a parent Firewall Policy for corporate rules and child policies for each application team that inherit from the parent.
Azure Firewall Policies support a hierarchical structure. A parent policy can define base rules that are inherited by child policies. Rules in the parent policy are always processed before rules in the child policy, ensuring that corporate security standards are enforced first.
Question 2: Which of the following Azure Firewall Policy features requires the Premium SKU to be enabled?
- DNS Proxy
- Threat intelligence-based filtering
- TLS Inspection (Correct answer)
- FQDN filtering in Network Rules
Correct answer: TLS Inspection
TLS Inspection, which allows the firewall to decrypt and inspect HTTPS traffic, is a feature exclusive to the Azure Firewall Premium SKU. The other features listed, such as DNS Proxy, Threat Intelligence, and FQDN filtering, are available in the Standard SKU.
Question 3: A network administrator is creating a new Azure Firewall Policy. Rules are organized within Rule Collections, which are in turn grouped into what higher-level container that is processed based on a priority value from 100 to 65,000?
- Rule Sets
- Action Groups
- Rule Collection Groups (Correct answer)
- Security Groups
Correct answer: Rule Collection Groups
In an Azure Firewall Policy, rules are placed in Rule Collections (DNAT, Network, or Application). These Rule Collections are contained within Rule Collection Groups, which are the primary unit of processing and are evaluated based on their priority number.
Question 4: An administrator needs to migrate an existing Azure Firewall that uses classic rules to a new Azure Firewall Policy without causing downtime. What is the recommended first step in this process?
- Create a blank Firewall Policy and associate it with the firewall, which automatically imports the rules.
- Delete all classic rules from the firewall before creating the new policy.
- Use the 'Migrate to firewall policy' option on the firewall's overview page to create a new policy from the existing rules. (Correct answer)
- Manually document all classic rules and recreate them one by one in a new Firewall Policy.
Correct answer: Use the 'Migrate to firewall policy' option on the firewall's overview page to create a new policy from the existing rules.
The Azure portal provides a built-in, non-disruptive migration path. On the firewall's overview page, selecting 'Migrate to firewall policy' will create a new policy resource based on the firewall's current classic rule configuration, which can then be associated.
Question 5: A parent Firewall Policy contains a Network Rule Collection Group with a priority of 300. A child policy inheriting from it contains a Network Rule Collection Group with a priority of 150. How will Azure Firewall process these rule collection groups?
- The parent policy's group will be processed first because parent rules always have precedence. (Correct answer)
- An error will occur because the priorities of the inherited and local groups conflict.
- The processing order is non-deterministic and can vary.
- The child policy's group will be processed first because it has a lower (higher priority) number.
Correct answer: The parent policy's group will be processed first because parent rules always have precedence.
When using policy inheritance, Rule Collection Groups from the parent policy are always processed before Rule Collection Groups in the child policy, regardless of their priority numbers. After the parent's rules are processed, the child's rules are then processed based on their own priority.
Question 6: An organization wants to use a single Azure Firewall Policy to manage the security rules for multiple Azure Firewall instances deployed across several different Azure regions. Which statement is true regarding this scenario?
- A Firewall Policy can only be associated with firewalls within the same region.
- A single Firewall Policy can be associated with multiple firewalls across different regions and subscriptions. (Correct answer)
- Each Azure Firewall requires a unique and dedicated Firewall Policy.
- Firewall Policies can only be associated with firewalls deployed within an Azure Virtual WAN hub.
Correct answer: A single Firewall Policy can be associated with multiple firewalls across different regions and subscriptions.
Azure Firewall Policy is a global resource that is designed for central management. A single policy can be created and associated with multiple Azure Firewall instances, regardless of whether they are in different regions or subscriptions, enabling consistent rule enforcement.
An organization wants to enforce a mandatory set of corporate security rules on all Azure Firewalls while allowing individual application teams to add their own specific rules.
The corporate rules must always be processed before the application-specific rules.
