A number of reports from end users indicate that internal and external communications are intermittent and not reliable. You verified the status of the switch ports and have determined that they are up and operational. You also noticed a very high level of link bandwidth utilization on those same ports. The current topology of the affected environment is shown in the exhibit.
What would be the cause of the reported issues?

• A.A lack of port-based ACLs filtering the traffic flows.
• B.A malformed route-based ACL improperly filtering traffic flows.
• C.A misconfigured interior gateway protocol (IGP).
• D.A lack of a loop-prevention mechanism or protocol.

Host-1 was recently added in the network and is attached to ge-0/0/10 on Switch-A.
Host-1 is powered on and has its interface configured with default Layer 2 settings and an IP
address on the 172.17.12.0/24 IP subnet.
Host-1's MAC address is not shown in Switch-A's bridging table.
What are three explanations for this state? (Choose three.)

• A.The ge-0/0/10 interface is not operationally or administratively up.
• B.The ge-0/0/10 interface is configured as an access port.
• C.The ge-0/0/10 interface does not have an associated IRB.
• D.The ge-0/0/10 interface is configured as a trunk port.
• E.The ge-0/0/10 interface has not received any traffic from Host-1.
