Tôi gặp khó khăn với các câu hỏi sau, các bạn có thể giải dùm tôi được không"
QUESTION NO: 70
You need VRF route to limit the effect of ______. (Choose two)
A. Route loops on the MPLS VPN backbone.
B. Malicious behavior on the MPLS VPN backbone.
C. Excessive hop count on the customer’s network.
D. Configuration errors on the MPLS VPN backbone.
QUESTION NO: 56
Which statement is true about the hardware requirements of MPLS?
A. Because you do not need to run a routing protocol on P-routers, they require less
memory than routers supporting classic IP routing.
B. Because of the additional processing and memory requirements needed to build the
LFIB, MPLS is only available on high end routers.
C. MPLS is available on low end routers, built their use is limited because of the
additional processing and memory requirements needed to build the LFIB.
D. Because P-routers do not need to carry routes outside the MPLD domain, they
require less memory than routers that support the same application using classic IP
routing.
QUESTION NO: 41
When should you disable redistribution of IPv4 routing updates between MP-BGP
neighbors?
A. When the network only supports MPLS VPNs.
B. When the network is using OSPF or ISIS instead of I-BGP as the network IGP.
C. When you want to reduce the number of labels that the P-router needs to store.
D. When you want to reduce the number of routes that the P-routers must store in their
global BGP routing table.
QUESTION NO: 24
You should run frame-mode MPLS over an ATM network _______. (Choose two)
A. In situations where ATM SVCs are not available.
B. On low end routers that cannot support the number of virtual circuits needed to run cell
mode.
C. In situations where the labeled packets must traverse ATM networks that do not support
MPLS.
D. In a migration scenario where the network is moving a classic IP over ATM to an
MPLS aware ATM network.
QUESTION NO: 18
How does a PE-router operating in the default frame mode distribute labels?
A. The PE-router distributes a label for every destination in its FIB.
B. The PE-router only distributes labels for destinations inside the MPLS domain.
C. The PE-router only distributes labels for destinations outside the MPLS domain.
D. The PE-router does not distribute labels. Label distribution is only done by the core
