When implementing MPLS VPNs between CE and PE routers, which of these statements is correct?
As a Network Engineer, it is necessary for you to know how to implement MPLS VPNs between Customer Edge and Provider Edge routers.
Refer to the following descriptions, which one is making sense?()

A. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution
B. If using IS-IS as the PE-CE routing protocol, no redistribution is required
C. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required
D. If PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required

2.單項選擇題When BGP is used as the PE-CE routing protocol, which of these statements is correct?()

A. On the CE router, PE neighbors must be configured in the VRF context on the CE router
B. On PE routers, the CE IBGP neighbors are configured in the global BGP configuration
C. On PE routers, the CE EBGP neighbors are configured in the VRF context
D. A separate BGP process must be used on the PE routers for CE routers so that they do not use the same BGP routing process as that used for the PE router's other provider neighbors

3.單項選擇題When EIGRP is used as the PE-CE routing protocol which of these statements is correct?()

A. EIGRP can be used only as the PE-CE routing protocol if the PE and CE routers are in the same AS
B. Other EIGRP AS routes are automatically advertised to the CE router and do not require a redistribution configuration command to be configured
C. Unlike other routing protocols that are used between PE and CE routers, EIGRP supports backdoor links
D. Configure of the VPN is only required on the PE router

A. CEF switching is only needed to forward labeled packets.
B. CEF switching is needed on both ingress and egress interfaces on which MPLS is enabled.
C. Interface-level CEF switching is needed only on egress interfaces that are sending IP packets on which the egress LSR performs the label imposition process.
D. Interface-level CEF switching is needed only on ingress interfaces that are receiving IP packets on which the ingress LSR performs the label imposition process.

5.單項選擇題Which of these tools should you use to compress VoIP packets on a low-speed Frame Replay circuit?()
