QUESTION: 41

As cells enter an aPipe service configured for vc-type atm-vcc, how does the ingress Provider Edge (PE) router handle the cell header Virtual Path Identifier/Virtual Channel Identifier (VPI/VCI) values?

The PE strips the cell headers and transports just the payload with a control word
The PE replaces the VPI/VCI with the MPLS service label and control word
The PE replaces the VPI/VCI with another set defined within the service context
The PE transports the original VPI/VCI along with the payload to the egress PE

Which statement correctly describes eNodeB-to-eNodeB X2 interface traffic flow in the Model 1 hub and spoke architecture Long Term Evolution (LTE) service model shown?

X2 traffic travels through the red Virtual Private LAN Service (VPLS) to the Mobility Management Entity (MME) pool and on to the target CSA router
The green Internet Enhanced Service (IES) provides the Layer 3 interfaces used for X2 eNodeB-to- eNodeB handoff traffic
Split horizon allows direct eNodeB-eNodeB handoff without the need to route through the green IES interfaces
The red VPLS supports Virtual Routing and Redundancy Protocol (VRRP) sessions for X2 inter- eNodeB Layer 3 interface resiliency

Which statement correctly describes the Model 1 hub and spoke architecture Long Term Evolution (LTE) service model shown?

The blue Internet Enhanced Service (IES) SAP interfaces include static Media Access Control (MAC) address entries for the eNodeBs
The red Virtual Private LAN Service (VPLS) provides the Layer 2 transport to support blue IES Virtual Routing and Redundancy Protocol (VRRP) sessions
The green IES spoke SDP interfaces include static MAC address entries for the eNodeBs
The blue IES interfaces forward traffic to external networks and the mobile core

Click on the exhibit.

Given the show command results shown and the following information;
* MLS1 interface L3_VLAN402 is the preferred Virtual Router ID (VRID) 1 master interface
* The master interface failed and later recovered
Why does the MLS2 interface L3_VLAN402 remain in the Master state?

You must configure a VRRP policy to control master recovery time
The VRRP VRID 1 configuration disallows preempting the existing master
SROS requires operator intervention to recover the VRRP master interface
The Layer 2 interface carrying the VRRP announcements is operationally down
