NEW QUESTION 34
Exhibit

Which two statements about the output shown in the exhibit are correct? (Choose two.)

The PE is attached to a single local site.

The connection has not flapped since it was initiated.

There has been a VLAN ID mismatch.

The PE router has the capability to pop flow labels

According to 1 and 2, BGP Layer 2 VPNs use BGP to distribute endpoint provisioning information and set up pseudowires between PE devices. BGP uses the Layer 2 VPN (L2VPN) Routing Information Base (RIB) to store endpoint provisioning information, which is updated each time any Layer 2 virtual forwarding instance (VFI) is configured. The prefix and path information is stored in the L2VPN database, which allows BGP to make decisions about the best path.
In the output shown in the exhibit, we can see some information about the L2VPN RIB and the pseudowire state. Based on this information, we can infer the following statements:
* The PE is attached to a single local site. This is correct because the output shows only one local site ID (1) under the L2VPN RIB section. A local site ID is a unique identifier for a site within a VPLS domain.
If there were multiple local sites attached to the PE, we would see multiple local site IDs with different prefixes.
* The connection has not flapped since it was initiated. This is correct because the output shows that the uptime of the pseudowire is equal to its total uptime (1w6d). This means that the pseudowire has been up for one week and six days without any interruption or flap.
* There has been a VLAN ID mismatch. This is not correct because the output shows that the remote and local VLAN IDs are both 0 under the pseudowire state section. A VLAN ID mismatch occurs when the remote and local VLAN IDs are different, which can cause traffic loss or misdelivery. If there was a VLAN ID mismatch, we would see different values for the remote and local VLAN IDs.
* The PE router has the capability to pop flow labels. This is correct because the output shows that the flow label pop bit is set under the pseudowire state section. The flow label pop bit indicates that the PE router can pop (remove) the MPLS flow label from the packet before forwarding it to the CE device.
The flow label is an optional MPLS label that can be used for load balancing or traffic engineering purposes.

NEW QUESTION 35
Referring to the exhibit, which statement is correct?

VPN routes are exported with the target:65512:1 and target:65512:2 route targets.

You cannot use the vrf-target and vrf-export statements in the same VRF.

VPN routes with the target:65512:1 and target:65512:2 route targets are imported.

VPN routes are exported with only the target:65512:1 route target

NEW QUESTION 36
You are configuring a BGP signaled Layer 2 VPN across your MPLS enabled core network. In this scenario, which statement is correct?

You must assign a unique site number to each attached site’s configuration.

This type of VPN only supports Ethernet interfaces when connecting to CE devices.

This type of VPN requires the support of the inet-vpn NLRI on all core BGP devices

You must use the same route-distinguiaher value on both PE devices.

NEW QUESTION 37
Exhibit

Referring to the exhibit, you must provide Internet access for VPN-A using CE-1 as the hub CE.
Which two statements are correct in this situation? (Choose two.)

You must use RIB groups to leak routes between the inet. o and vpn-a. inet. o tables.

RIB groups are not needed to leak routes between the inet. 0 and VPN-A. inet. 0 tables,

Internet traffic from Site 2 takes the path of PE-2 -> PE-1 -> GW-1.

Internet traffic from Site 2 takes the path of PE-2 -> PE-1 -> CE-1 -> PE-1 -> GW-1.

NEW QUESTION 38
