Your network contains an Active Directory forest.
Some users report experiencing difficulties signing in to domain controllers. You suspect that the service location (SRV) records might be causing the issue.
What are two possible commands that you can run to verify the SRV records? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
A. dnscmd /DirectoryPartitionlnfo
B. dcdiag.exe /test:DNS
C. dcdiag.exe/test:connectivity
D. dnscmd/IpValidate
E. dcdiag.exe /test:DnsRecordRegistration
F. dnscmd /info
B,E
I think its B and E.
I have tested this.
E has the wrong syntax. Might be a typo in the practice though.
PS C:\Windows\system32> dcdiag.exe /test:DnsRecordRegistration
Test not found. Please re-enter a valid test name.

dcdiag.exe /test:DNS /DnsRecordRegistration
This command verifies registration of the following resource records in DNS:
-alias (CNAME): the globally unique identifier (GUID)-based resource record that locates a replication partner
-host (A): the host resource record that contains the IP address of the domain controller
-LDAP SRV: the service (SRV) resource records that locate LDAP servers
-GC SRV: the service (SRV) resource records that locate global catalog servers
-PDC SRV: the service (SRV) resource records that locate primary domain controller (PDC) emulator operations masters
dcdiag.exe /test:DNS
Verifying dynamic update
If the basic DNS test shows that resource records do not exist in DNS, use the dynamic update test to determine why the Net Logon service did not register the
resource records automatically. To verify that the Active Directory domain zone is configured to accept secure dynamic updates and to perform registration of a test
record (_dcdiag_test_record), use the following procedure. The test record is deleted automatically after the test.
