After a recent DNS zone transfer, users report intermittent failures when resolving internal hostnames. The primary DNS server shows no errors, but the secondary server's logs show 'zone transfer failed' messages. Which action should you take to resolve the issue?

Restart the DNS service on the primary server.

Increase the TTL on all DNS records to reduce query load.

Verify the zone transfer settings and ensure the secondary server is authorized to request transfers.

Point all clients to the primary DNS server only.

Users report that they can access a website by its IP address but not by its hostname. The DNS server is responding to queries, and the website's A record exists. Which additional factor should you investigate?

The TTL of the A record and the client's DNS cache

A company has a hybrid environment with on-premises servers and cloud VMs. The on-premises servers sync time with an internal NTP server, while the cloud VMs use the cloud provider's NTP service. Users report authentication failures between the two environments. Which action should you take to resolve the issue?

Change the cloud VMs to use the internal NTP server.

Increase the authentication timeout on the servers.

Ensure both environments use the same time source or verify the offset between them.
