An engineer must configure interswitch VLAN communication between a Cisco switch and a third-party switch. Which action should be taken? configure ISL configure DSCP configure IEEE 802.1q configure IEEE 802.1p. An engineer must establish a trunk link between two switches. The neighboring switch is set to trunk or desirable mode. What action should be taken? configure switchport mode dynamic desirable configure switchport nonegotiate configure switchport trunk dynamic desirable configure switchport mode dynamic auto. Refer to the exhibit. A network administrator assumes a task to complete the connectivity between PC A and the File Server. Switch A and Switch B have been partially configured with VLANs 10, 11, 12 and 13. What is the next step in the configuration? Add PC A to VLAN 10 and the File Server to VLAN 11 for VLAN segmentation Add a router on a stick between Switch A and Switch B allowing for inter-VLAN routing Add PC A to the same subnet as the File Server allowing for intra-VLAN communication Add VLAN 13 to the trunk links on Switch A and Switch B for VLAN propagation. Refer to the exhibit. Which outcome is expected when PC_A sends data to PC_B? The source MAC address is changed The switch rewrites the source and destination MAC addresses with its own The destination MAC address is replaced with ffff.ffff.ffff The source and destination MAC addresses remain the same. An engineer requires a scratch interface to actively attempt to establish a trunk link with a neighbor switch. What command must be configured? switchport mode dynamic auto switchport nonegotiate switchport mode dynamic desirable switchport mode trunk.
