How are PDUs handled during the peer-communication process?
A. The Internet layer encapsulates data and attaches a header to create a PDU known as a frame
B. Header information within a PDU is required and can include information such as source and destination logical addressing
C. The link layer provides a service to the network layer by encapsulating the network-layer packet into a PDU called a segment
D. The application layer protocol begins the process by delivering PDUs to the transport layer

A. Creates a trunk with the neighboring switch based on the DTP request
B. Enables trunking on the interface
C. Trunking cannot take place on the port regardless of DTP requests
D. Sends a DTP communication that it wants to create a trunk with the neighboring switch
E. DTP frames are prevented from being generated from the port
B
Which of the following commands represents the format NetFlow export packets use?

D. ip flow-export version version
D
During root port election, what happens when the BPDUs with a lower root unique identifier value than its own bridge ID, are being received on multiple ports?
A. The switch elects the port that has the lowest-cost path to the root as its root port
B. The switch elects multiple root ports simultaneously
C. The switch elects the port that is closest to the root bridge
D. The switch elects the port that is receiving the BPDUs with the highest BID
A
Cisco Catalyst switches CAT1 and CAT2 have a connection between them using ports FA0/13. An 802.1Q trunk is configured between the two switches. On CAT1, VLAN 10 is chosen as native, but on CAT2 the native VLAN is not specified. What will happen in this scenario?
A. 802.1Q giants frames could saturate the link.
B. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send untagged frames.
C. A native VLAN mismatch error message will appear.
D. VLAN 10 on CAT1 and VLAN 1 on CAT2 will send tagged frames.
C

B. spanning-tree portfast
C. spanning-tree bpduguard enable
D. spanning-tree portfast bpduguard default
B
Which VLAN troubleshooting steps are used when there is no connection between PCs?
A. Use the [show interfaces switchport] command to see if the native VLAN matches on both sides
B. Use the [show interfaces trunk] command to check whether the VLAN is assigned the correct membership
C. Use the [show vlan] command to verify that the port is in the correct VLAN
D. Use the [show mac address-table] command to check which addresses were learned on a particular port and which VLAN that port is assigned
C, D
Which statements describe TCP characteristics?
