MPLS-0021
1. Connections in MPLS are known as-
A. Explicit Destination Paths (EDP)
B. Label Switched Paths (LSP)
C. Topology Directed Paths (TDP)
D. Destination-Switched Paths (DSP)
2. What does the acronym MPLS expand to?
A. Media Purpose Link Searching
B. Matching Path Link Synchronization
C. Multiple Path Latency Survey
D. Multiprotocol Label Switching
3. The most important reason for MPLS implementations is-
A. It ensures a high quality of service for certain types of traffic in the network,
B. It implements a new forwarding paradigm
C. MPLS can be leveraged for many applications such as traffic engineering, Layer 2 VPNs, Layer 3 VPNs, and optical signaling using the same signaling protocols.
D. Speed up the route lookup,
4. At what level of the OSI model are connections introduced?
A. Layer 2
B. Layer 3
C. Layer 1
D. Layer 4
5. What are signaling protocols used for in MPLS?
A. Signaling protocols are used to report traffic conditions to management systems
B. Signaling protocols are required to establish an LSP connection along the right path.
C. Signaling protocols are used to provide dynamic path routings
D. Signaling protocols are used to identify failed paths
6. Juniper Networks solves the MPLS route look up problem through?
A. Advanced search algorithms
B. Memory caching algorithms
C. Advanced data structures
D. Purpose built ASICs
7. What major architectural issue, has Juniper Networks confronted and solved, that otherwise limits MPLS implementation? (choose three)
A. High performance IP route lookup can be achieved without MPLS
B. Performance degradation during route instability which results in recalculation of complicated data structure and reiteration of the new data structure to memory.
C. Building the supporting data structures becomes very complicated and puts a lot of load on the router.
D. The router is less stable because it has to work a lot harder during periods of instability.
8. In MPLS forwarding tables are implemented as—
A. Radix trees
B. Parse tree
C. Associative arrays
D. Hash tables
9. In traditional IP-based networks, the practical forwarding paradigm that's been used is
A. Origination address-based forwarding
B. Destination address-based forwarding.
C. Registered address-based forwarding
D. Configured address-based forwarding.
10. Which of the following statements is true?
A. MPLS forwards packets based on “fast path” topology
B. MPLS buffers packets until it can build a best path map of the network
C. MPLS forwarding paradigm provides the ability to map the traffic to a topology
D. MPLS guarantees packet delivery by sending duplicate packets across different routes
