Juniper Enterprise Routing and Switching, Professional (JNCIP-ENT) 認定 JN0-650 試験問題 (Q51-Q56):

質問 # 51
Referring to the exhibit, how will router E quickly learn that the remote MAC addresses are no longer reachable through the router attached to the failed link?

正解：A


質問 # 52
A modified deficit round-robin scheduler is defined by which two variables? (Choose two.)

正解：C、D

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 # 53
You have created a private community VLAN called RND The private community VLAN works fine within switch S1, but traffic in the private RND community VLAN does not reach VLAN members connected to switch S2.
Which statement is correct in this scenario?

正解：D

解説：
Private VLANs (PVLANs) allow for granular port isolation within a single broadcast domain. When extending a PVLAN across multiple switches (S1 to S2), the secondary VLANs (Community or Isolated) must be preserved across the trunk links.
* 802.1Q Tagging (Option B):For traffic from aCommunity VLAN (RND)to reach members on a different switch, the Community VLAN must have its own802.1Q VLAN tag (VLAN ID)associated with it. When a frame from a community port on S1 traverses the trunk to S2, it is tagged with this specific secondary VLAN ID. S2 receives the tagged frame, identifies it as belonging to the RND community, and forwards it to the appropriate community or promiscuous ports.
* Why it fails without a tag:If the RND community is only defined locally on S1 without a global VLAN ID, the trunk port will not know how to distinguish that traffic from the Primary VLAN or other communities.
* Incorrect Options:Option Ais incorrect because the community VLANmusthave a different tag than the parent (Primary) VLAN to maintain the internal PVLAN logic.Option Cis incorrect because stripping tags would lead to the traffic being merged into the native VLAN or dropped.Option Dis incorrect because RND is a community VLAN; changing it to an isolated VLAN would change its behavior (preventing communication between members of that same group).


質問 # 54
Which statement is true regarding color-aware tricolor marking?

正解：B


質問 # 55
When configuring Q-in-Q tunneling, which type of tunneling involves the swapping of S-VLANs with C-VLANs?

正解：B

解説：
VLAN rewrites in Q-in-Q tunneling perform tag manipulation operations, including swapping S- VLAN tags with C-VLAN tags. This functionality is used when VLAN identifiers must be modified as frames traverse the provider network.
