   A campus network is being redesigned for high availability. The network team wants to ensure that the distribution layer has redundant devices and that the access layer has redundant uplinks to the distribution layer. They also want to avoid spanning-tree blocking of redundant links where possible. Which design best meets these requirements?

   • AUse a single distribution switch and rely on the access switches to provide redundancy.
   • BUse a Virtual Chassis for the access switches and connect them to a single distribution switch.
   • CUse a pair of distribution switches with MC-LAG, and connect each access switch to both distribution switches with a LAG.
   • DUse Spanning Tree Protocol (STP) with the root bridge set to one distribution switch, and connect access switches to both distribution switches with a single link each.

   What is the primary benefit of SRX chassis clustering for stateful failover?

   • AIt provides a backup power supply for the devices
   • BIt synchronizes session state so that active sessions are preserved during a failover
   • CIt increases the throughput of the firewall by combining the processing power of both nodes
   • DIt simplifies the configuration by using a single management IP address

   A campus network is being designed with redundant distribution switches. The network team wants to use link aggregation from the access switches to the distribution switches, but they are concerned about spanning-tree blocking one of the links. They also want to ensure that if one distribution switch fails, the access switch can still use the remaining link. Which solution should they implement?

   • AUse a regular LAG from the access switch to each distribution switch separately.
   • BUse MC-LAG on the distribution switches and a single LAG from the access switch to both distribution switches.
   • CUse a Virtual Chassis for the access switches and connect them to a single distribution switch.
   • DUse Spanning Tree Protocol (STP) with the root bridge set to one distribution switch and rely on STP to unblock the redundant link on failure.
