   A router has two interfaces: GigabitEthernet0/0 with IP 192.168.1.1/24 and GigabitEthernet0/1 with IP 10.0.0.1/24. A PC on the 192.168.1.0/24 network sends a packet to a server at 10.0.0.5. The router's routing table has a directly connected route for 10.0.0.0/24. What will the router do with the packet?

   • ABroadcast the packet on all interfaces to find the server
   • BSend the packet to the default gateway of the server
   • CForward the packet out GigabitEthernet0/1 to the server
   • DDrop the packet because the destination is not in the routing table

   A company runs a critical application on two servers behind a load balancer. The load balancer uses active health checks that send a TCP SYN to port 443 on each server. The application is healthy, but the health check fails because the servers only respond to HTTPS requests with a valid Host header. What is the most likely result?

   • AThe load balancer sends traffic to the servers but logs a warning
   • BThe load balancer switches to passive health checks
   • CThe load balancer continues to send traffic because the application is healthy
   • DThe load balancer marks the servers as down and stops sending traffic to them

   What is the primary function of a load balancer in a network?

   • AFilter traffic based on security policies to protect network boundaries
   • BForward packets between different IP networks based on routing tables
   • CForward frames between devices on the same LAN based on MAC addresses
   • DDistribute incoming traffic across multiple servers to optimize resource use and availability

   What is a key benefit of using a load balancer in front of a group of web servers?

   • AIt provides a single point of failure for the application
   • BIt improves availability and scalability by distributing traffic across multiple servers
   • CIt filters malicious traffic based on security policies
   • DIt increases the number of MAC addresses in the LAN

   A network administrator notices that a switch's MAC address table is full, and the switch is flooding frames to all ports. The administrator suspects a compromised device is generating many frames with random source MAC addresses. Which feature should be enabled on the switch ports to prevent this type of attack?

   • AVLAN trunking with allowed VLANs
   • BPort security with a maximum MAC address limit
   • CSpanning Tree Protocol (STP) with root guard
   • DLoad balancing with a hash algorithm
