A remote employee can establish a VPN connection to the corporate office but cannot access any resources on the internal network. The VPN client shows 'Connected'. Other remote employees on the same VPN server have no issues. What should the administrator investigate first?

The encryption algorithm configured on the VPN server.

The employee's local internet connection speed.

The client's assigned IP address and subnet mask.

The VPN server's certificate expiration date.

An organization has migrated a critical application to the cloud. Users in the main office report that the application is slow to respond. The application team confirms the cloud instance is not resource-constrained. Which test should the administrator run to determine if the issue is network-related?

Run a traceroute from the main office to the cloud application's public IP.

Check the DNS TTL settings for the application's hostname.

Review the cloud instance's security group rules.

Verify the VPN tunnel's authentication method.

An administrator is troubleshooting a DNS issue on a Windows workstation. The workstation is configured with a static IP and DNS server 10.0.0.53. The administrator runs 'nslookup server1.company.com' and receives a 'Non-existent domain' response. Other workstations on the same subnet can resolve the name. What is the most likely cause?

The workstation's subnet mask is incorrect.

The DNS server at 10.0.0.53 is down.

The workstation's DNS cache contains a negative entry for the hostname.

The hostname 'server1.company.com' does not exist in DNS.

A user reports that a website is unreachable by its hostname, but the site loads when the IP address is typed directly. Which step in the DNS resolution process is most likely failing?

The recursive resolver querying the root server

The authoritative server returning the IP address

The TTL expiring before the query completes

The client's DNS cache returning a stale or incorrect record
