This record can be analyzed as follows:

"p=reject" means that any email messages that fail DMARC authentication should be rejected by the recipient's mail server."rua=mailto:faruq@worldcm.onmicrosoft.com" specifies the email address where aggregate DMARC reports should be sent."ruf=mailto:dmarc-faruq@worldcm.onmicrosoft.com" specifies the email address where forensic DMARC reports should be sent."sp=reject" indicates that the policy for subdomains should be the same as for the main domain."fo=1" indicates that forensic reports should be generated for failed DMARC authentication messages."pct=100" indicates that DMARC checks should be applied to all messages. This can be removed as pct=100 is the default if there is no pct tag in the record."ri=864000" specifies the duration in seconds for which aggregate reports should be kept by the receiving mail server. In this case, the duration is set to 864,000 seconds (10 days)."adkim=s" specifies the alignment mode for the DKIM signature, indicating that strict alignment should be used."aspf=s" specifies the alignment mode for the SPF check, also indicating that strict alignment should be used.
