What is a default setting for NAT Translated Packets when the destination NAT translation is selected as Dynamic IP (with session distribution)?
- A. Round Robin
- B. Source IP Hash
- C. Least Sessions
- D. IP Hash
正解：A
解説：
When the destination NAT translation is selected as Dynamic IP (with session distribution), the firewall uses a round-robin algorithm to distribute sessions among the available IP addresses that are resolved from the FQDN. This option allows you to load-balance traffic to multiple servers that have dynamic IP addresses1. Reference: Destination NAT, NAT, Getting Started: Network Address Translation (NAT).

質問 # 28
Which path in PAN-OS 11.x would you follow to see how new and modified App-IDs impact a Security policy?
- A. Device > Dynamic Updates > Review Policies
- B. Objects > Dynamic Updates > Review Policies
- C. Objects > Dynamic Updates > Review App-IDs
- D. Device > Dynamic Updates > Review App-IDs
正解：D
解説：
To see how new and modified App-IDs impact your Security policy, you need to follow the path Device > Dynamic Updates > Review App-IDs on PAN-OS 11.x. This option allows you to perform a content update policy review for both downloaded and installed content. You can view the list of new and modified App-IDs and their descriptions, and see which Security policy rules are affected by them. You can also modify the rules or create new ones to adjust your Security policy as needed1. Reference: See How New and Modified App-IDs Impact Your Security Policy, Updated Certifications for PAN-OS 10.1, Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0) or [Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0)].
質問 # 29
What are two differences between an implicit dependency and an explicit dependency in App-ID? (Choose two.)
- A. An implicit dependency does not require the dependent application to be added in the security policy
- B. An explicit dependency requires the dependent application to be added in the security policy
- C. An explicit dependency does not require the dependent application to be added in the security policy
- D. An implicit dependency requires the dependent application to be added in the security policy
正解：A、B
質問 # 30
The Palo Alto Networks NGFW was configured with a single virtual router named VR-1 What changes are required on VR-1 to route traffic between two interfaces on the NGFW?
- A. Add interfaces to the virtual router
- B. Add a static routes to route between the two interfaces
- C. Enable the redistribution profile to redistribute connected routes
- D. Add zones attached to interfaces to the virtual router
正解：B
質問 # 31
An administrator wants to reference the same address object in Security policies on 100 Panorama managed firewalls, across 10 device groups and five templates.
Which configuration action should the administrator take when creating the address object?
- A. Tag the address object with the Global tag.
- B. Ensure that the Shared option is checked.
- C. Ensure that Disable Override is cleared.
- D. Ensure that the Shared option is cleared.
正解：B
解説：
To reference the same address object in Security policies on 100 Panorama-managed firewalls, across 10 device groups and five templates, the administrator should ensure that the Shared option is checked when creating the address object. This option allows the administrator to create a shared address object that is available to all device groups and templates on Panorama. The shared address object can then be used in multiple firewall policy rules, filters, and other functions1. This reduces the complexity and duplication of managing address objects across multiple firewalls2. References: Address Objects, Create a Shared Address Object, Certifications - Palo Alto Networks, Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0) or [Palo Alto Networks Certified Network Security Administrator (PAN-OS 10.0)].

質問 # 35
In which two types of NAT can oversubscription be used? (Choose two.)
- A. Static IP
- B. Dynamic IP
- C. Destination NAT
- D. Dynamic IP and Port (DIPP)
正解：B、D
解説：
Oversubscription is a feature that allows you to use more private IP addresses than public IP addresses for NAT. This means that multiple private IP addresses can share the same public IP address, as long as they use different ports. Oversubscription can be used in two types of NAT: Dynamic IP and Port (DIPP) and Dynamic IP. DIPP NAT translates both the source IP address and the source port number of the outgoing packets, and can have an oversubscription rate greater than 1. Dynamic IP NAT translates only the source IP address of the outgoing packets, and can have an oversubscription rate of 1 or less. Static IP and Destination NAT do not support oversubscription, as they require a one-to-one mapping between the private and public IP addresses. Reference: Source NAT, Configure NAT, NAT

質問 # 39
An address object of type IP Wildcard Mask can be referenced in which part of the configuration?
- A. NAT address pool
- B. Security policy rule
- C. ACC global filter
- D. external dynamic list
正解：B
解説：
You can use an address object of type IP Wildcard Mask only in a Security policy rule.
https://docs.paloaltonetworks.com/pan-os/9-0/pan-os-web-interface-help/objects/objects-addresses IP Wildcard Mask
-Enter an IP wildcard address in the format of an IPv4 address followed by a slash and a mask (which must begin with a zero); for example, 10.182.1.1/0.127.248.0. In the wildcard mask, a zero (0) bit indicates that the bit being compared must match the bit in the IP address that is covered by the 0. A one (1) bit in the mask is a wildcard bit, meaning the bit being compared need not match the bit in the IP address that is covered by the 1. Convert the IP address and the wildcard mask to binary. To illustrate the matching: on binary snippet 0011, a wildcard mask of 1010 results in four matches (0001, 0011, 1001, and 1011).
