Question 1 of 60

Refer to the exhibits.
A network engineer has worked with PC support to install a new PC. After correctly configuring the PCs interfaces with valid IP addresses, the PC is not able to ping other devices on the 192.168.13.0/24 network.
The output from the PC after executing the command ipconfig /all is below:
The network engineer executes the command show mac address-table on the N-series switch to which the PC is connected.
The output of the show mac address-table command is below.
What are two reasons that the PC is unable to ping other devices? (Choose two.)

The ARP table is corrupt on the PC and is not allowing the PC to register its MAC address with the switch.

The default gateway needs to be configured for the network 192.168.13.0/24 to ping devices on the 192.168.13.0/24 network.

The switch has not seen traffic from the PC and does not have an entry in the mac address table for the PC.

The switch is not registering MAC addresses in the MAC address table and needs to be reset.

The port on the N-Series switch that the PC is connected to is shut down.

Question 4 of 60

Refer to the exhibit of the N-series switches.
The exhibit shows a Layer 2 network between Host A (a Desktop Computer running Windows 7) and Host B (another Desktop Computer running Windows 7) and the list of VLANs Untagged (U) and Tagged (T) at each Ethernet interface: Host A transmits an Ethernet frame untagged on VLAN 1.
What will happen to the Ethernet frame?

SW2 drops the Ethernet frame when trying to transmit it out of interface E2 because the incoming and outgoing interfaces are Tagging/Untagging VLAN 1 differently.

The Ethernet frame is successfully delivered to Host.

STP drops the Ethernet frame because it cannot create an end-to-end loop free path between the switches for VLAN 1.

VLAN consistency protocol determines that the VLAN is not correctly Tagged/Untagged on all interfaces, an error will occur, and SW1 will drop the frame on
