To load only address objects from a PAN-OS saved configuration file into a VM-300 firewall that is in production, the administrator must follow these three steps:

C . Enter the configuration mode from the CLI: This step is necessary to prepare the firewall to accept the new configuration.

D . Use the load config partial command: This command allows the administrator to load only specific parts of the configuration, such as address objects, from a saved configuration file without overwriting the entire configuration. The command syntax typically looks like this: load config partial from <source-configuration> mode merge exclude everything but address objects.

E . Import named configuration snapshot through the web interface: This involves importing the configuration snapshot that contains the address objects through the web interface, but only after ensuring that the specific address objects are targeted and not the entire configuration.

When SSL Forward Proxy decryption is enabled, and clients using Chrome need to see browser warnings for websites with invalid certificates, the following options will satisfy the requirement:

A . Create a Decryption Profile with the Block sessions with expired certificates option enabled: This option ensures that sessions with expired certificates are blocked, which will present a warning to the user.

B . Create a self-signed Forward Untrust enabled certificate: This certificate will be used for websites with invalid or untrusted certificates, prompting the browser to display a warning.

These configurations ensure that users are properly warned when accessing sites with invalid certificates, allowing them to decide whether to proceed.

To fulfill the customer's requirement for log redundancy on logs forwarded from firewalls in a Panorama HA setup, the following configuration options are necessary:

B . Log redundancy must be enabled per Collector Group: This ensures that logs are redundantly stored across multiple log collectors within the same collector group.

C . A Collector Group must contain at least two Log Collectors: For log redundancy to work, there must be at least two log collectors in the collector group so that if one log collector fails, the other can continue to collect logs.

These configurations ensure that log data is replicated across multiple log collectors, providing redundancy and resilience in the event of a failure.

When a packet from an existing session is received by a firewall that is part of an HA (High Availability) pair:

D . The firewall takes ownership of the session from the peer firewall

In a high-availability configuration, if a firewall in an HA pair receives a packet for an existing session that it is not currently handling, it will take ownership of that session from the peer firewall. This ensures seamless continuity of the session and maintains the stateful nature of the firewall's session handling.

The interface deployments that support the Aggregate Ethernet (AE) Active configuration are:

B . LACP in Layer 3: Link Aggregation Control Protocol (LACP) can be used in Layer 3 interfaces to bundle multiple physical interfaces into a single logical interface for redundancy and increased bandwidth.

C . LACP in Layer 2: LACP can be used in Layer 2 interfaces to aggregate multiple Ethernet interfaces, enhancing throughput and providing failover capabilities within a Layer 2 network.

D . LACP in Virtual Wire: LACP can also be configured in Virtual Wire mode, which allows the firewall to aggregate interfaces while operating in a transparent mode, bridging traffic between interfaces without routing.

These configurations leverage LACP to improve network performance and reliability by combining multiple physical links into a single logical link.

To delete all of the unused address objects on the firewall, the best method is:

B . Using CLI execute request configuration address-objects remove-unused-objects

This CLI command is designed to identify and remove all unused address objects in the firewall's configuration. It is the most efficient and accurate method for cleaning up unused objects without manually checking each one.

The category of Vulnerability Signatures that is most likely to trigger false positive alerts is:

C . info-leak

Information leakage signatures are designed to detect attempts to access or disclose sensitive information. These signatures can be prone to false positives because benign activities or legitimate data transmissions can sometimes be mistakenly identified as information leaks.
