Question: 3

A bootstrap USB flash drive has been prepared using a Windows workstation to load the initial configuration of a Palo Alto Networks firewall that was previously being used in a lab. The USB flash drive was formatted using file system FAT32 and the initial configuration is stored in a file named init-cfg.txt. The firewall is currently running PAN-OS 10.0 and using a lab config. The contents of init-cgf.txt in the USB flash drive are as follows:

type=dhcp-client Ip-address= default-gateway= netmask= Ipv6-address= Ipv6-default-gateway= hostname=Ca-FW-DC1 panorama-server=10.5.107.20 panorama-server-2=10.5.107.21 tplname=FINANCE_TG4 dgname=finance_dg dns-primary=10.5.6.6 dns-secondary=10.5.6.7 op-command-modes-multi-vsys.jumbo-frame dhcp-send-hostname=yes dhcp-send-client-id=yes dhcp-accept-server-hostname=yes dhcp-accept-server-domain=yes

The USB flash drive has been inserted in the firewalls' USB port, and the firewall has been restarted using command> request restart system

Upon restart, the firewall fails to begin the bootstrapping process. The failure is caused because:

AThe USB must be formatted using the exi3 file system, FAT32 is

BFirewall must be in factory default state or have all private data deleted for bootstrapping

CThe bootstrap xml file is a required file, but it is missing

DPAN-OS version must be 9.1 x at a minimum, but the firewall is running 10.0x

EThe hostname is a required parameter, but it is missing in init-cfg.txt
