   A network diagram shows two routers (R1 and R2) connected to each other. R1 connects to switch S1, and R2 connects to switch S2. S1 hosts servers A and B; S2 hosts servers C and D. A single firewall sits between R1 and the internet. The company wants to eliminate the firewall as a single point of failure without adding a second internet link. Which change to the topology provides the most direct redundancy improvement?

   • AAdd a second link between S1 and S2 to improve server-to-server redundancy.
   • BConfigure both routers to use HSRP to provide gateway redundancy.
   • CAdd a second firewall in parallel with the existing one, connected to both R1 and the internet edge.
   • DConnect S1 directly to R2 and S2 directly to R1 to create a full mesh.

   A network diagram shows a core switch connecting to two distribution switches (DS1 and DS2). DS1 connects to access switches for VLAN 10 users, and DS2 connects to access switches for VLAN 20 users. Both distribution switches connect to a pair of firewalls (FW1 and FW2) in active/standby mode, which connect to the internet. The company wants to ensure that VLAN 10 users can reach the internet even if DS1 fails. What is the most effective change?

   • AConfigure HSRP on DS1 and DS2 for VLAN 10.
   • BAdd a second core switch and connect both distribution switches to it.
   • CConnect the access switches for VLAN 10 to both DS1 and DS2, and configure the appropriate VLANs on both.
   • DMove all VLAN 10 users to DS2.

   A topology diagram shows a core switch connected to two distribution switches. Each distribution switch connects to two access switches. The access switches connect to end users. What is the primary benefit of this hierarchical design?

   • AIt eliminates the need for a firewall
   • BIt provides redundancy and scalability
   • CIt simplifies the configuration of VLANs
   • DIt reduces the need for routing protocols
