Question 241

An engineer requires a switch interface to actively attempt to establish a trunk link with a neighbor switch. What command must be configured?

  1. switchport mode trunk
  2. switchport mode dynamic desirable
  3. switchport nonegotiate
  4. switchport mode dynamic auto

Question 242

Refer to the exhibit. After the election process, what is the root bridge in the HQ LAN? Switch 1: 0C:E0:38:81:32:58 - Switch 2: 0C:0E:15:22:1A:61 - Switch 3: 0C:0E:15:1D:3C:9A - Switch 4: 0C:E0:19:A1:4D:16 -

  1. Switch 1
  2. Switch 2
  3. Switch 3
  4. Switch 4

Question 243

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?

  1. configure switchport nonegotiate
  2. configure switchport mode dynamic desirable
  3. configure switchport mode dynamic auto
  4. configure switchport trunk dynamic desirable

Question 244

Which spanning-tree enhancement avoids the learning and listening states and immediately places ports in the forwarding state?

  1. BPDUfilter
  2. PortFast
  3. Backbonefast
  4. BPDUguard

Question 245

How does the dynamically-learned MAC address feature function?

  1. The CAM table is empty until ingress traffic arrives at each port
  2. Switches dynamically learn MAC addresses of each connecting CAM table.
  3. The ports are restricted and learn up to a maximum of 10 dynamically-learned addresses
  4. It requires a minimum number of secure MAC addresses to be filled dynamically
