Unit 5: Configuring Routing and Advanced Switching Test

Front

How do packet filtering firewalls apply rules to network traffic, and why might this approach be insufficient for certain modern threats?

Back

They inspect packet headers based on set rules.

Front

Explain how a stateful firewall differs from a packet filtering firewall when managing return traffic in a connection.

Back

It tracks the state of active connections.

Front

Design a VLAN configuration to separate traffic between administrative and guest networks, detailing any necessary access controls.

Back

Create separate VLAN IDs for administrative and guest traffic and configure inter-VLAN routing with restrictions.

Front

What transformation occurs in a PAT configuration for outbound traffic, and how does reverse mapping ensure return packets are correctly routed?

Back

PAT modifies source IPs and ports and restores them on return packets.

Front

In a network using PAT, why is it crucial to monitor port exhaustion, and what measures could be implemented to prevent it?

Back

Port exhaustion limits the number of simultaneous connections; using multiple public IPs can mitigate this.

Front

When troubleshooting incorrect gateway settings, how does analyzing a routing table provide clarity on connectivity issues?

Back

It shows the next-hop addresses and their reachability.

Front

Compare the implications of static versus default routes in managing traffic in a multi-router environment.

Back

Default routes simplify routing configuration, but static routes provide precise control.

Front

Why might a distance-vector routing protocol be less desirable than a link-state protocol in a large network?

Back

Distance-vector protocols are slower to converge.

Front

What is the primary role of administrative distance in dynamic routing protocols?

Back

To rank routes from multiple protocols.

Front

Which type of firewall provides the highest protection against application-layer threats?

Back

Next-Generation Firewall (NGFW).
