You plan to enforce LDAP signing and LDAP channel binding on all domain controllers. Before enforcing, you want to identify incompatible clients without breaking them. What should you deploy first? (Choose two)

To identify incompatible clients without immediately breaking them, you should first enable logging. Setting LdapEnforceChannelBinding=1 allows LDAP channel binding to be optional but logs clients that do not use it, providing valuable information for remediation. Similarly, enabling 'LDAP Interface Events' diagnostic logging to 2 on domain controllers will log Event ID 2889 for unsigned or unsealed LDAP binds, detailing the client IP address and identity. These two actions allow for a phased approach, identifying problematic clients before enforcing stricter security settings. Immediately setting 'Domain controller: LDAP server signing requirements' to 'Require signing' would break incompatible clients. Disabling NTLM is unrelated to LDAP signing or channel binding. Monitoring Security log event 4624 (account logon) does not provide the specific details needed for LDAP signing or channel binding incompatibility.
