   A campus network is experiencing congestion during peak hours. Voice traffic is being delayed, causing poor call quality. The network team has already marked voice traffic with DSCP EF at the access layer. What is the most effective next step to improve voice quality?

   • AIncrease the bandwidth of all links to eliminate congestion.
   • BRe-mark voice traffic to a lower priority to reduce congestion.
   • CConfigure QoS queuing and scheduling on the distribution and core switches to prioritize EF traffic.
   • DDisable QoS on the access layer to reduce overhead.

   A network administrator is troubleshooting a slow connection between two servers in different VLANs. The traffic path is: server A → access switch → distribution switch → core switch → distribution switch → access switch → server B. At which layer is the routing decision made to forward the packet from the source VLAN to the destination VLAN?

   • AAt the destination access switch, because it knows the destination MAC
   • BAt the core switch, because it is the central point of the network
   • CAt the access switch that receives the frame from server A
   • DAt the distribution switch that is the default gateway for the source VLAN

   A campus network has two distribution blocks, each with two distribution switches. The core layer consists of two core switches. A link between a distribution switch and a core switch fails. What is the primary role of the core layer in maintaining data flow?

   • ARoute all traffic directly between access switches without using the distribution layer.
   • BReconfigure the access layer switches to use a different distribution switch.
   • CProvide an alternate path through the redundant core links so traffic can continue between distribution blocks.
   • DShut down the distribution switch to prevent loops.
