NEW QUESTION # 19
A user is attempting to watch a high-definition video being streamed from the media server over the network. However, the user complains that the experienced video quality is poor. While logged on to router B, a Juniper Networks device, you notice that video packets are being dropped.
In this scenario, what would solve this problem?
- A. Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.
- B. Adjust the scheduler-map to support a higher transmit rate.
- C. Adjust the expedited-forwarding BA classifier to router B's ge-0/0/0 interface to support a higher transmit rate.
- D. Adjust the expedited-forwarding BA classifier on router B's ge-0/0/1 interface to support a higher transmit rate.
Answer: A
Explanation:
transmit rate is set on the scheduler, BA and classifier do not have transmit rate. scheduler-map=maps schedulers to fwd classes
NEW QUESTION # 20
Referring to the exhibit, traffic ingresses on interface ge-0/0/3 and egresses on interface ge-0/0/4.
Which queue does traffic with the IP precedence value of 100 use?
- A. expedited-forwarding
- B. network-control
- C. assured-forwarding
- D. best-effort
Answer: A
Explanation:
* Understanding the Configuration:
* The provided configuration and output snippets show how traffic is classified and assigned to different forwarding classes based on the IP precedence values.
* The inet-precedence classifier maps specific IP precedence values to forwarding classes with associated loss priorities.
* Review of Classifiers:
* IP Precedence Value 100:
* The IP precedence value 100 in binary is represented as 100 (binary for 4).
* Matching with Classifiers:
* According to the configuration shown in the exhibit:
classifiers {
inet-precedence cos;
}
* The classifier cos maps the following:
forwarding-class expedited-forwarding;
loss-priority low code-points 100;
* Conclusion:
* The IP precedence value 100 matches the expedited-forwarding forwarding class with low loss-priority as per the configuration.

NEW QUESTION # 28
Remote branches connect to the corporate WAN through access switches. The access switches connect to access ports on the WAN distribution switch, as shown in the exhibit. L2PT has previously been configured on the tunnel Layer 2 traffic across the WAN. You decide to move the L2PT tunnel endpoints to the access switches. When you apply the L2PT configuration to the access switches, the ports that connect the access switches to the distribution switch shut down.
Which action would solve this problem?
- A. Disable the BPDU block function on the access switches.
- B. Configure the links between the access switches and the distribution switch as a trunk port.
- C. Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.
- D. Disable the BPDU block function on the distribution switch.
Answer: B
Explanation:
* Understanding the Problem:
* The ports between the access switches and the distribution switch are shutting down when the L2PT configuration is applied. This typically happens due to a mismatch in port configurations or protocol incompatibilities.
* Examining the Configurations:
* L2PT (Layer 2 Protocol Tunneling) allows tunneling of Layer 2 traffic, which includes protocols like STP (Spanning Tree Protocol), CDP (Cisco Discovery Protocol), VTP (VLAN Trunking Protocol), etc. over a Layer 2 network.
* If the L2PT is applied on access ports, it may lead to conflicts or shut down the ports as access ports are typically not configured to handle Layer 2 protocol traffic beyond their designated VLAN.
* Solution: Configure Trunk Ports:
* By configuring the links between the access switches and the distribution switch as trunk ports, you allow multiple VLANs to be carried over a single physical link. Trunk ports can carry tagged traffic for multiple VLANs, which includes the tunneled Layer 2 protocols.
* This setup prevents the ports from shutting down and enables the correct tunneling of Layer 2 protocols.
References:
* Juniper Documentation on L2PT Configuration
* Troubleshooting Layer 2 Protocol Tunneling Issues
NEW QUESTION # 29
Which statement is correct about MSTP?

You are deploying new Juniper EX Series switches in a network that currently is using Cisco's Per- VLAN spanning tree plus (PVST+) and you must provide compatibility with this environment.
Which spanning tree protocol do you deploy in this scenario?
- A. VSTP
- B. RSTP
- C. STP
- D. MSTP
Answer: A
Explanation:
VSTP has the following benefits:
Connects devices that are not part of the network
Compatible with Cisco PVST+
VSTP and RSTP are the only spanning-tree protocols that can be configured concurrently on a device.
VSTP Restrictions
VSTP has these restrictions:
The EX Series switches EX4300, EX4600 and the QFX platforms QFX5100,QFX3500,QFX3600 support 510 Vlans on VSTP.
VSTP is not supported on the SRX platform - just STP/RSTP/MSTP are supported on SRX Series.
On EX Series (except EX9200) and QFX Series switches running Junos OS that supports ELS- VSTP can support up to 510 VLANs.
On EX9200 switches-VSTP can support up to 4000 VLANs.
On an EX Series switch running Junos OS that does not support ELS-VSTP can support up to
253 VLANs.

NEW QUESTION # 36
You are implementing the route summarization feature of OSPF.
Which two results do you achieve in this scenario? (Choose two.)
- A. It provides optimal routing in the network.
- B. It reduces the impact of topology changes on a device.
- C. It helps in migrating to future multi-area OSPF network designs.
- D. It reduced the routing table size, enabling devices to store and process less information.
Answer: B,D
Explanation:
OSPF Route Summarization Benefits:
* Reduces Routing Table Size: By summarizing routes, multiple specific routes are combined into a single route. This reduces the number of entries in the routing table, making it more efficient and easier for the devices to process. This is critical in large networks to maintain performance and manageability.
* Reduces Impact of Topology Changes: When a topology change occurs in one of the summarized routes, it does not need to propagate throughout the entire network. Only the summary route may need to be updated, which minimizes the impact and limits the scope of updates needed.
Implementation in OSPF:
* Configuration Example:
shell
Copy code
set protocols ospf area 0.0.0.0 range 10.1.0.0/16
* This command summarizes the routes in area 0.0.0.0 to a single route of 10.1.0.0/16.
References:
* The documents provided, such as "network-mgmt.pdf" and other relevant configuration guides, emphasize these benefits as fundamental to efficient OSPF deployment.
NEW QUESTION # 37
Referring to the exhibit, which two statements are correct? (Choose two.)
- A. The ge-0/0/10 interface supports PoE+.
