QUESTION 41
Click the Exhibit button.

Customer-1 wants the Service Provider to allow STP to operate normally on all ports but only allow the MX Series devices to manage the Layer 2 topology.
Referring to the exhibit, which feature needs to be implemented on all devices to accomplish this task?

root protection

MAC movement protection

BPDU protection

loop protection

QUESTION 42
Exhibit

The exhibit shows a topology with 1 Gbps interfaces between routers, and four RSVP LSPs operating with the respective bandwidth reservations.
Which path will be selected for a new LSP from R4 to R6 with a bandwidth reservation of 400 Mbps?

R4 -> R1 -> R2 -> R5 -> R6

R4 -> R5 -> R6

R4 -> R5 -> R2 -> R3 -> R6

R4 -> R1 -> R2 -> R3 -> R6

QUESTION 43
What are two benefits of using an OSPF designated router (DR)? (Choose two.)

Reduces the size of the link-state database.

Reduces LSA flooding on a broadcast segment.

Reduces LSA flooding throughout an OSPF area.

Reduces router resources used.

QUESTION 44
Click the Exhibit button.

Referring to the exhibit, from which device(s) does R3 learn about Route X?

both R2 and R1

R1 only

directly from the router in AS 64502

R2 only

R2 can not forward IBGP learned routes to another IBGP neighbor correct

QUESTION 45
Referring to the exhibit, which two statements are correct? (Choose two.)

The OSPF Interfaces are configured as point-to-point.

The ge-0/0’1.0 Interface is configured as passive.

The R2 device is an ABR.

Junos OS default OSPF hello timers and dead intervals are used on all interfaces.

QUESTION 46
Exhibit

Referring to the exhibit, what will happen to untagged frames?

The untagged frames are dropped.

The untagged frames are load balanced between VLAN 10 and VLAN 20.

The untagged frames are associated with VLAN 10.

The untagged frames are associated with VLAN 20.

In the exhibit, the interface is configured with thenative-vlan-id 20parameter. This means that any untagged frames arriving on this interface will be associated with VLAN 20. The native VLAN serves as the default VLAN for untagged frames on a trunk port.

QUESTION 47
You want to enable a routing platform with redundant REs to switch from a primary RE to a backup RE without alerting peer nodes. Which two technologies would you use to satisfy this requirement? (Choose two.)

GRES

VRRP

NSR

ISSU

Graceful Routing Engine Switchover (GRES) and Nonstop Active Routing (NSR) are two features used in Junos OS to provide high availability. GRES allows for the stateful failover of the Routing Engine, and NSR allows for the continuation of packet forwarding and protocol states during a Routing Engine switchover. These technologies ensure that peer nodes are not alerted during a switchover. VRRP and ISSU serve different purposes and do not apply to this specific requirement.

Juniper Networks documentation on High Availability: High Availability Features

QUESTION 48
Which two protocols are capable of distributing labels for segment routing? (Choose two.)

RSVP

LDP

IS-IS

OSPF

Segment routing labels can be distributed by link-state routing protocols such as IS-IS and OSPF, which have been extended to support segment routing capabilities.References:

QUESTION 49
Exhibit

Which two statements are correct about the information shown in the exhibit? (Choose two.)

The root bridge is reachable using the ge-0/0/14 interface.

This switch is the root bridge for this spanning tree topology.

This switch has a bridge priority of 8k.

The root bridge’s priority Is 4k.

The exhibit shows the output of the command show spanning-tree bridge, which provides information about the spanning tree status of the switch. From the output, we can see that the switch has a bridge ID different from the root ID, which implies that this switch is not the root bridge. The “Topology change initiator” field shows ge-0/0/14, which indicates that the last topology change occurred on this interface, and this is also the interface used to reach the root bridge.

QUESTION 50
Click the Exhibit button.

In the network shown in the exhibit, all switches are configured with the default STP root bridge priority, and Switch A has been selected as root. You recently added the older Switch D into the network as an access switch, and notice it has taken over as root.
Which configuration would solve this problem?

QUESTION 51
Click the Exhibit.

Referring to the exhibit, which statement is correct about MVRP?

AS1’s VLAN ID list is missing an entry for VLAN 300.

ES2 is not interested in VLAN 300.

AS1 is not allowing ES2 access to VLAN 300.

ES1 is not advertising VLAN 300 to AS1.

QUESTION 52
What Is a key differentiators of generate routes from aggregate routes?

Generate routes use a forwarding next hop.

Generate routes have a default next-hop value of reject.

Generate routes have a default preference value of 210.

Generate routes cannot be used as a gateway of last resort.

QUESTION 53
You are establishing RSVP LSPs through your MPLS-enabled network. You are asked to ensure that the LSPs will support end-to-end class-of-service handling.
Which statement is correct in this scenario?

Configure ultimate-hop-popping on the egress device.

Configure implicit-null on all MPLS-enabled devices.

Configure explicit-null on all MPLS-enabled devices.

Configure entropy-label on the egress device.

QUESTION 54
When working with an MPLS LSP, what will the install 172.16.6.0/24 active command accomplish?

The command will swap the prefix from inet.0 to inet.3

The command will swap the prefix from inet.3 to inet.0

The command will install the prefix in inet.0 rather than inet.3

The command will install the prefix in inet.3 rather than inet.0

QUESTION 55
Click the Exhibit button. Which two topologies shown in the exhibit could be implemented without a spanning-tree protocol? (Choose two.)

ring

tree

star

mesh

QUESTION 56
Which two statements are correct about the behavior of IS-IS metrics? (Choose two.)

Wide metrics enable interfaces to advertise metrics larger than 63.

By default, the metric of an interface is calculated based on the speed of the interface.

Wide metrics enable an interface to advertise different metrics at Level 1 and Level 2.

By default, all physical interfaces have a metric of 10.

Wide metrics in IS-IS allow for a larger metric value than what is available with narrow metrics, which supports a maximum of 63. Wide metrics also enable an interface to advertise different metrics for Level 1 and Level 2, allowing for more flexible routing policies and greater scalability in large networks.References:
