The router is an ABR.

The router is not an ABR.

The ge-1/1/0 interface is configured as secondary for Area 100.

NO.39 Which statement is correct about MSTP?

MSTP enables mapping multiple independent spanning-tree instances onto one physical topology.

MSTP enables dynamic discovery of Layer 2 neighbors.

MSTP dynamically manages VLAN registration in a LAN.

MSTP uses stacked VLAN tags to extend a Layer 2 Ethernet connection between multiple sites.

NO.40 Referring to the exhibit, how is R1learning the route from R2? R2 has an export policy with external type 2 configured.

R2 has interface ge-0/0 configured as a passive interface under OSPFv3.

R2 has interface ge-0/0/2 configured as a passive interface under OSPFv3.

R2 has an interface policy with external type 1 configured.

R2 has interface ge-0/0/2 configured in another area under OSPFv3.

NO.41 Which three MSTP parameters must match on all switches in the same MST region? (Choose three.)

forwarding delay

bridge priority

revision number

MSTI-to-VLAN mapping

configuration name

NO.42 You are deploying IP phones in your enterprise network that must receive their power through their Ethernet connection. You are using your EX Series switch’s PoE ports that support IEEE 802.3af.
In this scenario, what is the maximum amount of power allocated to each interface?

10.2 W

15.4 W

30 W

50 W

NO.43 You are deploying IP phones in your enterprise networks. When plugged in, the IP phones must automatically negotiate the power requirements for the new connection with the EX Series switches. In this scenario, which protocol should be used to enable this behavior?

CDP

MP-BGP

LLDP-MED

LLDP

NO.44 Which two statements are correct about the deployment of EVPN-VXLAN on QFX Series devices? (Choose two.)

Type 1 route advertisements always have the single-active flag set to 1.

Junos OS supports underlay replication for BUM traffic forwarding.

Junos OS supports ingress replication for BUM traffic forwarding.

Type 1 route advertisements always have the single-active flag set to 0.

BUM Traffic Forwarding
Junos devices that use MPLS encapsulation for EVPNs can only use ingress replication at this time.
Ingress replication means, to flood traffic to remote PE routers, the traffic has to be replicated, once for each remote PE router.
The EVPN label for this BUM traffic is learned per PE router from the route type 3, inclusive multicast Ethernet tag route.
This table shows the format of the inclusive multicast Ethernet tag route.
All-Active Redundancy (4)
This diagram shows the format of the type 1 route, A-D route per ES. The split horizon label is advertised as part of an extended community attached to the type 1 route. The split horizon label is also called the ESI label. The extended community also indicates what type of redundancy mode is used for this given ESI: single-active represented by binary 1 or active-active represented by binary 0.

NO.45 Referring to the log shown in the exhibit, what is the problem with the OSPF adjacency establishment?

The interface IP addresses on the subnet are duplicates.

There is an MDS authentication mismatch.

The referenced IP address does not exist on the network segment.

The OSPF database description packet is malformed.

NO.46 You are configuring MSTP to prevent loops in your Layer 2 network. After applying the configuration, you notice that MSTO is not working correctly.

Referring to the exhibit, what is causing the problem?

Too many VLANs have been defined.

Context identifier must be specified.

MSTI-to-VLAN mappings must be the same.

Incorrect revision number is used.

NO.47 Referring to the exhibit, which two statements are correct? (Choose two.)

The host that the route is associated with is multihomed to two leaf nodes.

The route is a Type 1 EVPN route.

The route is a Type 2 EVPN route.

The host that the route is associated with is single-homed to one leaf node.

NO.48 When redistributing IGP routes into BGP. what information .s used by default on Junos platforms to determine the BGP route’s MED attribute value?

routing information base

the IGP route preference

the IGP Metric

route protocol source

NO.49 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?

Router E receives Type 2 withdrawal messages from router D.

Router E receives Type 1 withdrawal messages from router D.

Router E receives Type 1 withdrawal messages from router C.

Router E receives Type 2 withdrawal messages from router C.

NO.50 Your EX Series switch has IP telephones and computers connected to a single switch port. You are considering implementing the voice VLAN feature to help with this setup. In this scenario, which two statements are correct? (Choose two.)

The voice VLAN feature must be used with LLDP-MED to associate VLAN ID and 802.1p values with the traffic.

The interfaces must be configured as access ports.

Assigning the incoming voice and data traffic to separate VLANs enables the ability to prioritize the traffic using CoS.

The voice VLAN feature will enable incoming tagged data and voice traffic to be associated with separate VLANs.

NO.51 You want to create an OSPF area that only contains intra-area route information in the form of Type 1 and Type 2 LSAs.
In this scenario, which area is needed to accomplish this task?

totally non-to-stubby area

totally stubby area

stub area

non-to-stubby area

A totally stubby area (TSA) is a stub area in which summary link-state advertisement (type 3 LSAs) are not sent. A default summary LSA, with a prefix of 0.0. 0.0/0 is originated into the stub area by an ABR, so that devices in the area can forward all traffic for which a specific route is not known, via ABR.

NO.52 A customer needs to pass Layer 2 protocols between sites.
Which protocol or standard would be required to implement connectivity on EX4300, EX3400, and EX2300 devices?

Q-in-Q

IGMP

VPLS

OSPF

NO.53 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?

Adjust the scheduler for the expedited-forwarding forwarding class to support a higher transmit rate.

Adjust the expedited-forwarding BA classifier to router B’s ge-0/0/0 interface to support a higher transmit rate.

Adjust the scheduler-map to support a higher transmit rate.

Adjust the expedited-forwarding BA classifier on router B’s ge-0/0/1 interface to support a higher transmit rate.

transmit rate is set on the scheduler, BA and classifier do not have transmit rate. scheduler-map=maps schedulers to fwd classes

NO.54 You are redistributing static routes into an OSPF area. Which two statement are true is this scenario? (Choose two.)

The external route advertisements have a domain scope.

The area must be stub area.

The area must be the backbone area.

The routes can be advertised in type LSAs.

NO.55 Which statement is correct about CoS policers on Junos devices?

Traffic that exceeds a policer’s traffic profile can be dropped or assigned to a specific drop profile.

A policer can assign in-profile traffic to a specific forwarding class.

A policer does not alter in-profile traffic.

Policers can be configured to buffer traffic that exceeds the policer’s traffic profile.

NO.56 You are adding VNI 101 to your EVPN-VXLAN network, but traffic is not being sent to received.
Referring to the exhibit, which configuration statement will solve the problem?

set routing-instances EVPN1 instance-type evpn

set routing-instances EVPN1 vxlan encapsulate-inner-vlan

set routing-instances EVPN1 bridge-domains BD-101 vxlan vni 101

set routing-instances EVPN1 vrf-table-label
