What is the primary purpose of NAT in a network?

To encrypt IP traffic between two sites.

To filter traffic based on application-layer protocols.

To translate private IP addresses to public IP addresses for communication across the internet.

To assign IP addresses to hosts automatically.

A network engineer is configuring NTP for a set of routers. The routers are in different time zones, and the engineer wants all logs to show accurate local time. The engineer has configured the correct time zone on each router and pointed them to the same NTP server. After synchronization, the logs on one router show the correct local time, but the logs on another router are off by one hour. What is the most likely cause?

The second router is using a different NTP server

The second router has the wrong time zone or daylight saving time settings

The second router is not synchronized to the NTP server

The NTP server is providing incorrect time

A user reports that they can access a website by IP address but not by its hostname. Other users on the same network can access the site by hostname without issue. The user's workstation has a static IP configuration. What is the most likely cause?

The website's DNS record has been deleted

The user's subnet mask is incorrect

The user's default gateway is misconfigured

The user's DNS server address is incorrect or missing

A company hosts a web server on an internal private IP address. External users need to reach this server using a public IP address. The firewall has a single public IP available. Which NAT configuration should be used to allow inbound connections from the internet to the internal web server?

Dynamic NAT with a pool of public IPs

PAT using the public IP and unique port numbers

Destination NAT with a one-to-many mapping

Static NAT with a one-to-one mapping between the public IP and the private IP of the web server
