Palo Alto Networks Certified Network Security Administrator (PCNSA)Initial Configuration and ManagementEasy
A network administrator needs to ensure that the Palo Alto Networks firewall's clock is always accurate and synchronized with a reliable time source. Which protocol is used for this purpose and where is it primarily configured on the firewall?
- ADHCP; Network > Interfaces > Management
- BDNS; Device > Setup > Services
- CSNMP; Device > Setup > Management
- DNTP; Device > Setup > Services
Show answer & explanationAnswer & explanation
Correct answer: D. NTP; Device > Setup > Services
NTP (Network Time Protocol) is used to synchronize the firewall's clock with external time servers. This configuration is found under Device > Setup > Services in the web interface.
Why the other options are wrong
- A. DHCP is for IP address assignment, not time synchronization, and its configuration for the management interface is under Network > Interfaces.
- B. DNS is for name resolution, not time synchronization.
- C. SNMP is for monitoring, not time synchronization.
NTP Configuration
Network Time Protocol (NTP) is used to synchronize the system clock of the Palo Alto Networks firewall with accurate time sources, crucial for logging, certificate validation, and policy enforcement.
- Ensures accurate timestamps for logs.
- Important for certificate validity periods.
- Configured under Device > Setup > Services.
Memory trick: NTP Services Deliver Perfect Time.
