Juniper Enterprise Routing and Switching, Professional (JNCIP-ENT) 認定 JN0-650 試験問題 (Q98-Q103):

質問 # 98
According to IETF standards, which two statements are correct about EVPN/VXLAN deployments? (Choose two.)

A. Up to 16 million VXLAN broadcast domains can exist.
B. IP packets within the same broadcast domain are forwarded unchanged.
C. Layer 2 frames within the same broadcast domain are forwarded unchanged.
D. Up to 16 million EVPN broadcast domains can exist.

正解：A、C

解説：
In EVPN/VXLAN deployments, each VXLAN Network Identifier (VNI) can support up to 16 million broadcast domains, allowing massive scalability. Within a broadcast domain, Layer 2 frames are encapsulated for transport across the VXLAN overlay but are forwarded unchanged within the same VNI. IP packets are encapsulated inside VXLAN and are not forwarded natively unchanged.

質問 # 99
You are enabling CoS throughout your enterprise network using the DSCP bits. You plan to use an MF classifier on all edge devices while using BA classifiers on all transit core devices In this scenario, what should you use to provide consistent handling of traffic?

A. You should implement rewrite rules on the edge devices ' egress interfaces to rewrite the DSCP bits as it leaves the device toward the core.
B. You should implement rewrite rules on the core devices ' egress interfaces to rewrite the DSCP bits as it leaves the device toward other core devices.
C. You should implement rewrite rules on the core devices ' ingress interfaces to rewrite the DSCP bits as it enters the device.
D. You should implement rewrite rules on the edge devices ' ingress interfaces to rewrite the DSCP bits as it enters the device.

正解：A

解説：
This scenario describes the standard transition of Class of Service (CoS) metadata from the network edge to the network core.
MF vs. BA Classification: Edge devices use Multifield (MF) classifiers because incoming traffic often lacks markings. MF classification assigns traffic to an internal forwarding class based on multiple fields (IPs, ports, etc.). Core devices use Behavior Aggregate (BA) classifiers because they are faster; they only look at the CoS bits (like DSCP) in the header to determine the forwarding class.
The Problem: Internal forwarding class assignments made by an MF classifier on the edge device do not automatically travel with the packet. If the packet leaves the edge device with its original (potentially zeroed) DSCP bits, the core device ' s BA classifier will not be able to identify the priority.
The Solution (Option A): You must implement rewrite rules on the egress interfaces of the edge devices. A rewrite rule takes the internal forwarding class and loss priority assigned by the MF classifier and " writes " the corresponding DSCP value into the packet header as it exits toward the core. This ensures that the core device sees the correct DSCP marking and can apply the appropriate BA classification.
Incorrect Options: Rewrite rules are strictly an egress function to modify the packet for the next hop.
Applying them on ingress (Option B) or core ingress (Option C) does not solve the problem of ensuring the packet header reflects the classification logic used during the internal switching process of the edge device.

質問 # 100
Which of the following would be a reason to use BGP over an IGP like OSPF or IS-IS?

A. When designing a network with a single link between each pair of routers.
B. When low convergence time is the highest priority.
C. When connecting to multiple, different organizations' ASes.
D. When routing within a single AS.

正解：C

質問 # 101
A modified deficit round-robin scheduler is defined by which two variables? (Choose two.)

A. Layer 3 fields
B. buffer size
C. transmit rate
D. Layer 2 fields

正解：B、C

解説：
In Junos OS Class of Service (CoS), a scheduler is the mechanism used to assign resources to the various egress queues on an interface. Specifically, when utilizing a modified deficit round-robin (MDRR) or weighted round-robin algorithm to service these queues, the scheduler ' s behavior is defined by two primary variables:
* Transmit Rate (Option A): This variable defines the minimum guaranteed bandwidth for a queue.
In the context of a deficit round-robin algorithm, the transmit rate serves as the weight for the queue.
Queues with higher transmit rates receive a larger " quantum " of data they can send during each round- robin cycle compared to queues with lower rates.
* Buffer Size (Option C): This variable defines the amount of memory (buffer space) allocated to the queue. It ensures that the queue can hold a certain amount of delayed traffic during periods of congestion to prevent immediate packet drops. The buffer size can be configured as a percentage of the total interface buffer or as a temporal value.
Why other options are incorrect:
* Layer 2 and Layer 3 fields (Options B & D): These fields are utilized by classifiers (Behavior Aggregate or Multifield) to identify and group traffic into forwarding classes. They are used before the scheduling process begins and do not define the resource allocation of the scheduler itself.

質問 # 102
You must ensure that all routes in the 10.0.0/8 address range are not advertised outside of your AS.
Which well-known BGP community should be assigned to these addresses to accomplish this task?

A. no-peer
B. internet
C. no-advertise
D. no-export

正解：D
