   How does link aggregation provide fault tolerance?

   • ABy using a single high-speed link that is less likely to fail
   • BBy allowing traffic to continue over the remaining links if one link fails
   • CBy encrypting traffic to prevent data loss
   • DBy automatically rerouting traffic to a backup data center

   What is the primary purpose of Spanning Tree Protocol (STP) in a switched network?

   • ATo increase the bandwidth of a single switch link
   • BTo prevent network loops while allowing redundant paths
   • CTo provide load balancing across multiple switches
   • DTo encrypt traffic between switches

   A company is designing a network for a critical application that must have high availability. The design includes redundant switches, redundant links, and a load balancer. The network team wants to ensure that a single failure of any network component does not cause an outage. What is the most important principle to apply?

   • AUse the fastest possible hardware to minimize failure probability.
   • BImplement a single, highly reliable network path.
   • CEliminate single points of failure by providing redundant paths and automatic failover.
   • DUse a virtual IP address on all servers.

   A small business has a single server connected to a switch with two 1 Gbps Ethernet cables. The server hosts a file share that is accessed by 20 users. The network administrator wants to increase throughput and provide redundancy in case one cable or switch port fails. What is the most appropriate solution?

   • AEnable Spanning Tree Protocol on the switch ports connected to the server.
   • BAssign each NIC a different IP address and use round-robin DNS.
   • CConfigure the two NICs as a single link aggregation group (LAG) with 802.3ad.
   • DUse a virtual IP address that floats between the two NICs.

   How do virtual switches support fault tolerance in virtualized environments?

   • ABy providing redundant virtual network paths that can fail over if a physical link fails
   • BBy encrypting all traffic between virtual machines
   • CBy eliminating the need for physical network adapters
   • DBy storing virtual machine data on the host's local disk
