   A load balancer distributes traffic to four application servers. The servers have different hardware specifications. The administrator wants to ensure that more powerful servers receive a larger share of traffic. Which load balancing method should be used?

   • ALeast connections
   • BRound-robin
   • CSource IP hash
   • DWeighted round-robin

   A network engineer is troubleshooting intermittent connectivity between two hosts on the same VLAN. The hosts are connected to two different access switches, and the switches are interconnected. The engineer notices that the MAC address table on the access switch connected to host A does not list the MAC address of host B. What is the most likely reason for this?

   • AThe switch is using a routing table to forward frames between the two hosts, so MAC addresses are not needed.
   • BThe switch is filtering frames based on a security policy that blocks the MAC address of host B.
   • CThe switch only learns MAC addresses from frames that are received on its ports, and host B's frames are not traversing this switch.
   • DThe switch is routing the frames at Layer 3 and therefore does not need to learn MAC addresses.

   A small office has a single LAN with 40 PCs and a server. The office recently added a second subnet for guest Wi-Fi. The network administrator needs to ensure that PCs on the main LAN can reach the guest subnet's default gateway, but the guest subnet should not be able to initiate connections to the main LAN. Which two components must be configured to meet this requirement?

   • AA router with a routing protocol and a load balancer
   • BA firewall with a DMZ and a switch with STP
   • CA switch with port security and a firewall with NAT
   • DA switch with VLANs and a router with an ACL

   A router receives a packet destined for 203.0.113.10. The routing table has the following entries: 203.0.113.0/24 via 192.0.2.1, 0.0.0.0/0 via 198.51.100.1, and 203.0.113.0/25 via 192.0.2.2. Which next hop will the router use?

   • AThe packet is dropped
   • B198.51.100.1
   • C192.0.2.2
   • D192.0.2.1
