Users report that the network is slower than usual when accessing on-premises email.

To confirm the issue of slow network performance when accessing on-premises email, a network technician should compare the network baselines to the current network status. Here’s why:

Reviewing logging levels of network devices (Option A) may provide information about device behavior but won’t directly confirm the email performance issue.

Checking audit logs (Option B) is useful for security purposes but doesn’t specifically address network performance.

Verifying LDAP accounts (Option D) is relevant for authentication but doesn’t directly relate to network performance.

Therefore, the correct answer is C. Compare the network baselines to the current network status
