A new PoE+VoIP handset was added to an EX Series device. The handset is experiencing connectivity issues.
The EX Series device's committed configuration includes the set PoE interface all telemetry command. You look at the telemetry log in the device to review power consumption and you notice entries have not been occurring for days.
What would cause telemetry logging to stop?

• A.Telemetry logging only works on Enhanced PoE VoIP handsets.
• B.Telemetry logging only occurs for one hour by default.
• C.Telemetry logging stops when all reserved power for PoE has been consumed.
• D.Telemetry logging stops when the logging file reaches 128 KB.

Click the Exhibit.

You have deployed Sparse Mode multicast in your network using the IGP metrics shown in the exhibit.
Which path will (*, G) traffic follow form the source to the receiver before the (S, G) state is registered?

• A.Source, R1, R2, R3, R6, Receiver
• B.Source, R1, R2, R5, R2, R3, R6 Receiver
• C.Source, R1, R4, R5, R6, Receiver
• D.Source, R1, R2, R5, R6, Receiver

You have certainly implemented the configuration shown in the exhibit. After committing these changes, the community devices connected to AS-1 are not able to communicate with the appropriate community devices connected to AS-2.
What must be done to allow these community devices to communicate?

• A.You must configure an isolation VLAN ID Under the pvlan-200 on the AS2
• B.switch You must configure the ge-0/0/10 interface on AS1 AS THE VPLAN on both switches
• C.You must configure an isolation VLAN ID under the VLAN 200 ON both switches
• D.You must configure the ge-0/012 interface on both switches as P VLAN trunks

You configured static mode power management on an EX4300 to provide PoE power to telephone and access point equipment.
Which statement is correct regarding the PoE power budget?

• A.The power budgeted to ports will adjust to how much power a device actually uses.
• B.The power budgeted will be based on the device class connected to each port.
• C.Power is budgeted to a port even if no device is connected to the port.
• D.Power is budgeted to devices on a first come, first served basis as devices are connected.

Which statement is correct about MSTP?

• A.MSTP dynamically manages VLAN registration in a LAN.
• B.MSTP enables mapping multiple independent spanning-tree instances onto one physical topology.
• C.MSTP uses stacked VLAN tags to extend a Layer 2 Ethernet connection between multiple sites.
• D.MSTP enables dynamic discovery of Layer 2 neighbors.
