A Cisco router is configured as a DHCP server for a /24 subnet. The administrator wants to assign a specific IP address to a server based on its MAC address. Which configuration method should be used?

Use DHCP snooping to reserve the IP.

Use the 'ip dhcp pool' with 'network' and rely on DHCP to assign the same IP.

Exclude the IP and configure a static IP on the server.

Configure a manual binding in the DHCP pool.

Your campus network uses a pair of distribution switches as the default gateway for multiple VLANs. You want to utilize both switches for forwarding traffic while still providing redundancy. Which FHRP should you choose to achieve this?

Static default route with floating route

After configuring PAT on a router, users can browse the internet, but an internal server cannot be reached from outside. 'show ip nat translations' shows no translation for the server's public IP. What is the most likely cause?

The static NAT statement for the server is missing or incorrect.

The inside interface is not configured correctly.

The server's default gateway is wrong.

A financial services company requires that all network devices synchronize their clocks to a central time source. They are concerned about security and want to prevent unauthorized devices from updating their time. Which NTP configuration should you implement on the Cisco routers?

Use NTP broadcast mode on all interfaces.

Configure NTP authentication with a shared key on all clients and the server.

Set the NTP stratum to 1 on all routers.

You are configuring a Cisco router as a DHCP server for a new subnet (192.168.10.0/24). The network has a printer that must always receive the same IP address (192.168.10.50). You also need to exclude the first 10 addresses for static devices. Which configuration steps are required?

Use a DHCP relay to forward requests to an external server.

Create a DHCP pool and specify the network only; the router will automatically reserve the printer IP.

Create a DHCP pool, specify the network, exclude 192.168.10.1-10, and add a manual binding for the printer.

Exclude the printer IP and rely on dynamic assignment for all devices.
