NetSec-Analyst Object Configuration Creation And Application — Timed 20 Questions

Question 1

When creating a Service object, what is the maximum number of ports that can be defined in a single Service object?

Accepted Answer

Unlimited, provided they are within the protocol's range. A single service object can define one port, a range of ports, or multiple individual ports separated by commas.

Answer

1

Answer

Only one port is allowed

Answer

10

Question 2

What is the purpose of the 'Description' field in an object configuration?

Accepted Answer

It is used to identify the object in logs. The description field provides an optional, human-readable note to help administrators document the purpose of the object.

Answer

It determines the object's color

Answer

It restricts access to the object

Answer

It is required for policy matching

Question 3

When creating a new tag, what is the default color assigned if not specified?

Accepted Answer

None/System Default. If no specific color is selected, the firewall assigns a default color or no color depending on the interface version.

Answer

Green

Answer

Red

Answer

Blue

Question 4

What is the function of the 'Commit' operation regarding objects?

Accepted Answer

It pushes the configuration changes to the data plane. Objects created in the configuration are only active and enforced on the firewall after a 'Commit' is performed.

Answer

It deletes the object

Answer

It saves the object to the disk

Answer

It creates the object

Question 5

What are the limitations of FQDN address objects? (Choose THREE)

Accepted Answer

They require the firewall to successfully resolve the FQDN. Option A is correct because an FQDN address object is resolved by the firewall itself, so the firewall must successfully resolve the domain name to an IP address before the object can be used in policy. Option D is correct because for that resolution to succeed, the firewall needs network reachability to a configured DNS server (or a valid DNS proxy/forwarder path). Option E is correct because when FQDN objects are used with TLS/SSL traffic, matching can depend on the SNI presented by the client; if the SNI does not match the FQDN, the traffic may not match the object. Option B is incorrect because FQDN address objects are not limited to internal IPs; they can resolve to public or private addresses depending on DNS. Option C is incorrect because FQDN address objects can be referenced in NAT policies where destination or source address matching is required.

Answer

They are only supported for internal IPs

Answer

They cannot be used in NAT policies

Question 6

An administrator needs to create a custom Service Object for a legacy application that uses both TCP port 8080 and UDP port 8080. How should this be configured in PAN-OS?

Accepted Answer

Create two separate Service Objects, one for TCP 8080 and one for UDP 8080.. PAN-OS does not support multiple transport protocols in a single service object definition.

Answer

Use the 'Application' override feature to define custom ports.

Answer

Create a Service Group and add the port 8080 to it twice.

Answer

Create one Service Object with 'TCP/UDP' selected in the protocol field.

Answer

null

Question 7

A security analyst is configuring a PAN-OS firewall to allow outbound SSH traffic from the internal zone to a specific external server. The analyst creates a custom Service object named 'SSH-Custom' with protocol TCP and destination port 22. When applying the policy, the firewall rejects the configuration because the Service object is incomplete. What is the most likely missing element?

Accepted Answer

Destination port range. A Service object in PAN-OS requires a protocol (TCP or UDP) and a destination port (or range). The scenario describes a Service object with protocol TCP and destination port 22, but the firewall rejects it as incomplete. The missing element is the destination port range, which must be explicitly defined. Source port, application identification, and timeout are not required components of a Service object.

Answer

Source port range

Answer

Application identification

Answer

Timeout value

Question 8

An administrator is creating a new Address Object in Strata Cloud Manager to represent a server that is reachable at the IPv4 address 203.0.113.45 and also at the IPv6 address 2001:db8::45. The server must be referenced by a single object in a security policy. What should the administrator do?

Accepted Answer

Create one Address Object and add both the IPv4 address 203.0.113.45 and the IPv6 address 2001:db8::45 as separate address entries within that object.. A single Address Object supports multiple address entries, so an administrator can add both the IPv4 and IPv6 addresses to one object. This satisfies the requirement of referencing the server by a single object and avoids unnecessary object proliferation. Using separate objects or incompatible types would not meet the stated goal.

Answer

Create two separate Address Objects, one for IPv4 and one for IPv6, and place both in an Address Group.

Answer

Create one Address Object with type 'IP Netmask' and enter 203.0.113.45/32, then add 2001:db8::45/128 as a second value in the same object.

Answer

Create one Address Object with type 'IP Range' spanning 203.0.113.45 to 2001:db8::45.

Question 9

A network security analyst is configuring a new Application Object in SCM to identify a custom internal application that uses TCP ports 8080 and 8443. The analyst needs to ensure the object can be used in a Security Policy rule to allow this application while blocking all other traffic. Which two actions are required when creating this custom Application Object? (Choose two.)

Accepted Answer

Define the application's signature or port/protocol mapping so the firewall can identify the traffic.. Creating a custom Application Object requires defining how the firewall identifies the application, which includes the protocol and port mappings, and ensuring the object has a proper signature or definition. These elements allow the firewall to match traffic for the custom application in a Security Policy rule. Zone assignment, category metadata, and SSL decryption are not prerequisites for the object itself.

Answer

Enable SSL decryption on the object so the firewall can inspect the application payload.

Answer

Specify the category and subcategory for the application to enable proper policy grouping.

Answer

Assign the object to a Security Zone before it can be referenced in a policy.

Question 10

A security engineer must create an External Dynamic List (EDL) object in SCM to block traffic from a vendor-published list of malicious IPs. The vendor provides the list over HTTPS and updates it every hour. Which two configuration elements are required for the EDL to function as intended? (Choose two.)

Accepted Answer

An object type selection of IP, Domain, URL, or Predefined IP.. An EDL object requires a source URL and an explicit type indicating whether it holds IPs, domains, URLs, or predefined entries. The refresh interval is tunable but not mandatory, client certificates apply only to mutual TLS, and enforcement is handled by policy rules rather than by profiles attached to the EDL. Those two elements are the minimum needed for the firewall to fetch and correctly interpret the vendor list.

Answer

A predefined security profile bound to the EDL to enforce blocking.

Answer

A recurring refresh interval that matches the vendor's hourly update cadence.

Answer

A client certificate uploaded to SCM for mutual TLS authentication with the vendor.

Question 11

A network security analyst is creating a new Address Object for a server that will be referenced in multiple security policies. The server's IP address is 192.168.10.50/24, and it is expected to remain static. Which of the following is the most appropriate configuration for this Address Object?

Accepted Answer

Create an Address Object with type 'IP Netmask' and value 192.168.10.50/24.. For a static server with a known IP and subnet mask, the most precise and standard object type is 'IP Netmask', which defines a single host with its subnet mask. This ensures the object represents only that server and integrates cleanly into policies. Other types either broaden the match, introduce DNS dependency, or use unnecessary constructs.

Answer

Create an Address Object with type 'IP Wildcard' and value 192.168.10.50/0.0.0.255.

Answer

Create an Address Object with type 'FQDN' and value server.example.com.

Answer

Create an Address Object with type 'IP Range' and value 192.168.10.50-192.168.10.50.

Question 12

A security engineer is configuring a Dynamic Address Group (DAG) on a PAN-OS firewall. The DAG uses a filter that references tags applied by a third-party system via the User-ID agent. After committing, the DAG appears empty. The engineer verifies that the tags are being received by the firewall. What is the most likely reason for the DAG not populating?

Accepted Answer

The tags are not registered as dynamic tags in the firewall.. Dynamic Address Groups rely on dynamic tags registered on the firewall. Even if tags are received from an external source, they must be registered as dynamic tags for the DAG filter to match them. Without this registration, the DAG remains empty. The other options are not prerequisites for DAG population.

Answer

The DAG requires a static address object to be added first.

Answer

The DAG filter syntax is incorrect.

Answer

The firewall's DNS resolution is failing.

Question 13

An analyst is preparing to create a new custom Application object in Strata Cloud Manager to identify an internal application that uses a non-standard protocol over UDP. The analyst wants to ensure the object is defined correctly and can be referenced in a security policy. Which two configuration elements are required when defining the custom Application object? (Choose two.)

Accepted Answer

A unique name for the custom Application object. A custom Application object requires a unique name and the protocol and port that identify the traffic, since no existing App-ID signature covers the internal tool. These two elements allow the object to be saved, referenced in policy, and matched against the correct sessions. Tags, decryption profiles, and parent application assignments are not required for this object type.

Answer

A parent application category assignment for App-ID classification

Answer

A tag that links the application to a Dynamic Address Group

Answer

An SSL decryption profile to inspect the application's payload

Question 14

A security analyst is configuring a Dynamic Address Group (DAG) that should automatically include all servers tagged with 'Web' and 'Production'. The tagging is done via the firewall's dynamic address group feature. Which two of the following are required for the DAG to populate correctly? (Choose two.)

Accepted Answer

The servers must have the tags 'Web' and 'Production' applied via the dynamic address group's source.. For a Dynamic Address Group to populate, the tags used in the filter must be registered in the system, and the target servers must have those tags applied to their IP addresses via a dynamic source. Without tag registration, the filter cannot evaluate; without tag application, no addresses match. Other options are either not required or are part of the filter configuration but not prerequisites for population.

Answer

The DAG must be configured with a filter that uses a logical AND between the tags 'Web' and 'Production'.

Answer

The firewall must have a valid support license for dynamic address groups.

Answer

A static address object for each server must exist and be linked to the DAG.

Question 15

A security administrator is creating a Service Object for a custom application that uses TCP ports 8080 and 8443. The application also requires UDP port 53 for DNS queries. The administrator wants to create a single Service Object that encompasses all these ports. Which of the following is the correct approach?

Accepted Answer

Create a Service Object with protocol TCP and destination ports 8080, 8443, and protocol UDP with destination port 53 within the same object.. A single Service Object in Palo Alto Networks can contain multiple protocols and ports. You can specify TCP ports 8080 and 8443, and also add UDP port 53. This consolidates the application's port requirements into one object, simplifying policy management. The other options either create multiple objects or use incorrect methods.

Answer

Create a Service Object with protocol TCP and destination ports 8080, 8443, and a separate Service Object for UDP 53, then use both in the policy.

Answer

Create a Service Object with protocol TCP and destination port 8080-8443, and include UDP port 53 by using a custom application signature.

Answer

Create a Service Object with protocol TCP and destination port 8080-8443, and another Service Object for UDP port 53, then group them in a Service Group.

Question 16

An administrator is creating a new Application Filter to control access to various applications. They want to include applications that are categorized as 'peer-to-peer' and have a risk level of 4 or higher. They also want to exclude applications that are known to use evasive techniques. Which two configurations should they apply to the Application Filter? (Choose two.)

Accepted Answer

Set the Category to 'peer-to-peer'.. The administrator needs to filter applications by category 'peer-to-peer' and risk level 4 or higher. These two criteria are set directly in the Application Filter. Excluding evasive applications is not directly supported via a characteristic exclusion in the filter; instead, the filter includes applications based on selected attributes. Therefore, the two correct configurations are setting the category and setting the risk.

Answer

Set the Subcategory to 'file-sharing'.

Answer

Set the Characteristics to 'evasive' and mark it as exclude.

Answer

Set the Technology to 'client-server'.

Question 17

A security analyst is creating a new Security Policy rule and needs to reference a specific server by its IP address. The server's IP is 10.1.1.5. The analyst wants to ensure that if the server's IP changes in the future, the policy automatically updates. Which object type should the analyst use?

Accepted Answer

FQDN Address Object. An FQDN Address Object is designed to resolve a hostname to an IP and keep it updated. If the server's IP changes, the firewall will perform DNS resolution and update the object, ensuring the policy remains current. The other object types are static and would not adapt to IP changes.

Answer

Dynamic Address Group

Answer

Address Object with static IP 10.1.1.5

Answer

IP Range Address Object

Question 18

A security analyst is defining a new Service Object in Strata Cloud Manager to represent a custom application that uses TCP port 8443 for management and UDP port 8443 for data. The application also requires ICMP echo requests for health checks. The analyst wants to minimize the number of objects while ensuring the policy matches all required traffic. Which configuration should the analyst use?

Accepted Answer

Create a Service Group that contains one Service Object for TCP port 8443, one for UDP port 8443, and one for ICMP.. Service Groups allow multiple Service Objects to be combined into a single reference for policy. Since each Service Object defines a single protocol and port, the analyst must create separate objects for TCP 8443, UDP 8443, and ICMP, then place them in a Service Group. This satisfies the requirement to match all traffic while keeping the policy rule concise and manageable.

Answer

Create a single Service Object with protocol TCP and UDP, destination port 8443, and a separate Service Object for ICMP; then group them in a Service Group.

Answer

Create a single Service Object with protocol TCP, destination port 8443; then create a separate Service Object for UDP port 8443 and a third for ICMP. Group them in a Service Group.

Answer

Create a single Service Object with protocol TCP, destination port 8443, and add a second destination port for UDP 8443 in the same object.

Question 19

A security analyst is configuring a new Service Object for a custom application that uses UDP port 500 and 4500 for IPsec NAT-T. The analyst wants to ensure the firewall correctly identifies and allows this traffic. Which configuration is required?

Accepted Answer

Create a Service Object with protocol UDP and destination ports 500,4500.. IPsec NAT-T uses UDP ports 500 and 4500. A Service Object must be configured with the UDP protocol and these destination ports to correctly match the traffic. This allows the firewall to identify the service and apply security policy. Using TCP or an Application Object would not be appropriate for this scenario.

Answer

Create a Service Object with protocol TCP and destination ports 500,4500.

Answer

Create a Service Group that includes UDP 500 and UDP 4500.

Answer

Create an Application Object with protocol UDP and ports 500,4500.

Question 20

You are configuring an Address Object in Strata Cloud Manager for a new web server. Which field must be unique within the configuration scope?

Accepted Answer

Object Name. The name field of an object must be unique within its context (Device Group or Snippet) to prevent configuration conflicts.

Answer

Tag

Answer

IP Netmask
