What is the new designation for the MPLS EXP (experimental) bits? A. QoS bits B. traffic class bits C. flow bits D. precedence bits Answer: BExplanation: To avoid misunderstanding about how this field may be used, it has become increasinglynecessary to rename this field. This document changes the name of the EXP field to the "TrafficClass field" ("TC field"). In doing so, it also updates documents that define the current use of theEXP field. ReferencE. Answer: A,BExplanation: QUESTION NO: 382 Which two options are signaling protocols that are used in MPLS? (Choose two.) A. LDP B. RSVP C. BFD D. LISP E. CLNS F. CDP Cisco 400-101 Exam "Pass Any Exam.

* Signaling is the means by which LSRs all along the path know that they are a part of a given LSP. It is a signaling function by which the LSR knows that the internal transit path for the LSP depicted goes from Interface 2 to Interface 4. * Label distribution is the means by which an LSR tells an upstream LSR what label value to use for a particular LSP. There are four protocols that can perform the label distribution function: * Label Distribution Protocol (LDP) * Resource Reservation Protocol with Traffic Engineering Extensions (RSVP-TE) * Constraint-Based Routed LDP (CR-LDP) * Multiprotocol BGP LDP and RSVP-TE are the two most commonly used label distribution protocols ReferencE. - distribution.html QUESTION NO: 383 Which option is an incorrect design consideration when deploying OSPF areas? A. area 1 - area 0 - MPLS VPN backbone - area 0 - area 2 B. area 1 - MPLS VPN backbone - area 2 C. area 1 - MPLS VPN backbone - area 1 D. area 2 - area 0 - MPLS VPN backbone - area 1 E. area 0 - area 2 - MPLS VPN superbackbone - area 1 Answer: E Explanation: In the case of MPLS-VPN Backbone as The OSPF superbackbone behaves exactly like Area 0 in regular OSPF, so we cannot have two different area 0’s that are not directly connected to each other. When area 0 connects to the superbackbone, it simply becomes an extension of area 0. QUESTION NO: 384 Refer to the exhibit. Cisco 400-101 Exam "Pass Any Exam. Any Time." - 311

Implement Dead Peer Detection to detect communication loss. C. Configure AES for encryption of transported data. D. Configure SHA-1 for encryption of transported data. E. Deploy IPsec hardware acceleration to minimize router memory overhead. F. Configure QoS services only on the head-end router. Cisco 400-101 Exam "Pass Any Exam. Any Time." - 312

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
