Which mode is necessary to configure an EtherChannel between two switches without using a negotiation protocol?
on
After the Spanning Tree Protocol converges, what action does PortFast take on ports receiving BPDUs?
Shut down the port.
What is the main functionality of a hypervisor in virtual machines?
Virtualizing physical components like CPU and memory
In switch configuration shown in the exhibit, what error needs to be corrected based on the output from switch 1?
Native VLAN mismatch
What OSPF network type is seen on a serial interface running encapsulation PPP by default?
Point-to-point
When PortFast is enabled on an interface connected to another switch, what issue might arise?
Failure to detect switching loops causing broadcast storms
What impact does connecting virtualized servers directly to a separate switch from the hypervisor have on efficiency?
Decreases efficiency by adding unnecessary hops

Point-to-point
What feature on the Cisco Wireless LAN Controller restricts management access from specific networks?
CPU ACL
What action is taken by a Cisco IP phone when it receives untagged data traffic from an attached PC?
It allows the traffic to pass through unchanged.
What will happen if cable length limits are exceeded?
