A user reports that the VPN connection drops every few minutes, causing applications to lose connectivity. The VPN client shows 'tunnel established' but then reconnects. Which cause is most likely?

The VPN server is rejecting the user's credentials.

The user's local DNS is misconfigured.

The user's internet connection is too slow.

The VPN tunnel is timing out due to keepalive settings.

A user's browser cannot load any external websites, but internal sites work fine. The browser is configured to use a proxy server. Which proxy-related issue is the most likely cause?

The user's network cable is disconnected.

The proxy server is unreachable or down.

The user's DNS server is not resolving external domain names.

A UDP-based application is failing to communicate between two hosts. Which symptom is most consistent with a blocked UDP port?

The application works normally because UDP is not affected by port blocking.

The application times out because UDP has no handshake to detect the block.

The application receives an ICMP 'Port Unreachable' message immediately.

The application reports a 'Connection refused' error.

A company uses a proxy for all outbound web traffic. Remote users connect via VPN and are configured to use the proxy for internal and external web traffic. Internal users can access a cloud application, but remote users cannot. The proxy logs show no requests from the remote users. What is the most likely cause?

The remote user's NAT is preventing the VPN connection

The cloud application is blocking VPN IP addresses

The proxy is blocking the cloud application's domain

The VPN is not routing the proxy's IP address to the remote user

A user reports that an application inside the corporate network can reach the internet, but external users cannot reach an internal web server. The administrator verifies that the web server is running and the firewall permits inbound HTTPS. Which NAT-related issue is the most likely cause?

The web server is using a private IP address that is not routable on the internet.

The NAT translation table is full, so new translations cannot be created.

The DNS record for the web server points to a public IP that is not associated with the NAT pool.

The web server's default gateway is set to the wrong router.
