SQL Script
declare #xmldata as xml
set #xmldata= (SELECT CONVERT(XML, BulkColumn) AS BulkColumn
FROM OPENROWSET(BULK 'C:\Users\ag03536\Documents\New folder\updated.xml', SINGLE_BLOB)as X)
SELECT
x.Rec.query('./DeviceRecord').value('.','varchar(120)')
,x.Rec.query('./IP').value('.','varchar(20)')
,x.Rec.query('./FQDN').value('.','varchar(20)')
FROM #xmldata.nodes('./root') as x(rec)

Answer 1

First you have to check, whether the XML is read propperly. Use this after reading your XML into the variable:
SELECT #xmldata;
Secondly all your values live in a default namespace. You have to declare it:
WITH XMLNAMESPACES(DEFAULT 'http://www.archer-tech.com/')
Third, your query should read all nested <DeviceRecord> entries probably, you need .nodes() down to this level. The full query should be something like this:
WITH XMLNAMESPACES(DEFAULT 'http://www.archer-tech.com/')
SELECT
x.Rec.value('(IP/text())[1]','varchar(20)') AS DevRec_ID
,x.Rec.value('(FQDN/text())[1]','varchar(20)') AS DevRec_FQDN
--The rest should be the same approach...
FROM #xmldata.nodes('/*:root/DeviceRecord') as x(rec)
EDIT: Your node <root> is not part of the default namespace.
I used a wildcard (*:root)
