NEW QUESTION 23
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.

NEW QUESTION 24
You have configured class mode power management on an EX4300 to provide PoE power to telephone and security camera equipment. You want to ensure that security camera power takes priority over telephone power.
Which two actions would solve this problem? (Choose two.)

Connect the security cameras to the lowest port numbers on the switch.

Set the power priority to high on ports connected to security cameras.

Set the maximum power settings on ports connected to security cameras.

Set the power priority to low on ports connected to security cameras.

https://www.juniper.net/documentation//en_US/junos/topics/concept/poe-overview.html#jd0e1522 Thus you must set interfaces that connect to critical powered devices, such as security cameras and emergency phones, to high priority. Among PoE interfaces that have the same assigned priority, power priority is determined by the port number, with lower-numbered ports having higher priority.

NEW QUESTION 25
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.

NEW QUESTION 26
Which three statements are correct about EVPN route types? (Choose three.)

Type 3 routes carry replication information.

Type 2 routes carry endpoint MAC address information.

Type 2 routes carry endpoint IP address information.

Type 5 routes carry replication information.

Type 1 routes carry endpoint MAC address information.

The EVPN control plane advertises the following types of information:
Route type 1 – This is an Ethernet Auto-Discovery (EAD) route type used to advertise Ethernet segment identifier, Ethernet Tag ID, and EVPN instance information. EAD route advertisements may be sent for each EVPN instance or for each Ethernet segment.
Route type 2 – This advertises endpoint reachability information, including MAC and IP addresses of the endpoints or VTEPs.
Route type 3 – This performs multicast router advertisement, announcing the capability and intention to use ingress replication for specific VNIs.
Route type 4 – This is an Ethernet Segment route used to advertise the Ethernet segment identifier, IP address length, and the originating router’s IP address.
Route type 5 – This is an IP prefix route used to advertise internal IP subnet and externally learned routes to a VXLAN network.

NEW QUESTION 27
What is a supplicant in 802.1x authentication?

the device that prevents the end user device’s access until it is authenticated

the authenticating device

the device being authenticated

the RADIUS server

NEW QUESTION 28
You are asked to configure 802.1X on your access ports to allow only a single device to authenticate.
In this scenario, which configuration would you use?

multiple supplicant mode

MAC authentication mode

single-secure supplicant mode

single supplicant mode

Single supplicant mode authenticates only the first end device that connects to an authenticator port. All other end devices connecting to the authenticator port after the first has connected successfully, whether they are
802.1X-enabled or not, are permitted access to the port without further authentication. If the first authenticated end device logs out, all other end devices are locked out until an end device authenticates. Single-secure supplicant mode authenticates only one end device to connect to an authenticator port. No other end device can connect to the authenticator port until the first logs out

NEW QUESTION 29
Which address range is used for source-specific multicast?

239.0.0.0/8

233.0.0.0/8

232.0.0.0/8

224.2.0.0/16

NEW QUESTION 30
Referring to the exhibit, which LSA type is used to advertise 192.168.1.0/24 to R5?

Type 5

Type 4

Type 3

Type 7

* Area-1 has no external connections. However, Area-1 has static route (172.16.31.0/24) that are not internal OSPF route. You can limit the external route advertisements to the area and advertise the static routes by designating the area an NSSA. In an NSSA, the ASBR (vMX1) generates NSSA external (Type 7) LSAs and floods them into the NSSA, where they are contained. Type-7 LSAs allow an NSSA to support the presence of ASBR and their corresponding external routing information. The ABR (vMX2) converts Type-7 LSAs into Type-5 External LSAs and leaks them to the other areas, but external routes from other areas are not advertised within the NSSA. An admin should check this and

NEW QUESTION 31
Referring to the exhibit, anycast RP is implemented to ensure multicast service availability. The source is currently sending multicast traffic using group 239.1.1.1 and R3 is receiving PIM register messages, but R2 does not have active source information. In this scenario, what are two methods to receive the active source information on R2? (Choose two.)

Configure an RP set in PIM on R1, allowing R1 to forward PIM register messages to R2 and R3 in the set.

Configure an MSDP protocol between R2 and R3.

Configure an RP set in PIM on R2 and R3, allowing the RPs to forward PIM register messages to the other RPs in the set.

Configure an MSDP protocol between R1 and R2.

NEW QUESTION 32
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?

no-export

no-peer

internet

no-advertise

For specifying the BGP community attribute only, you also can specify community-ids as one of the following well-known community names defined in RFC 1997:
no-advertise – Routes containing this community name are not advertised to other BGP peers.
no-export – Routes containing this community name are not advertised outside a BGP confederation boundary.
no-export-subconfed – Routes containing this community are advertised to IBGP peers with the same AS number, but not to members of other confederations.
llgr-stale – Adds a community to a long-lived stale route when it is readvertised.
no-llgr – Marks routes which a BGP speaker does not want to be retained by LLGR. The Notification message feature does not have any associated configuration parameters.

NEW QUESTION 33
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?

Configure the links between the access switches and the distribution switch as a trunk port.

Disable the BPDU block function on the access switches.

Disable the BPDU block function on the distribution switch.

Configure a GRE tunnel to encapsulate the L2PT traffic across the WAN.

Access interfaces in an L2PT-enabled VLAN should not receive L2PT-tunneled PDUs. If an access interface does receive L2PT-tunneled PDUs, there might be a loop in the network, and the device will shut down the interface.
https://www.juniper.net/documentation/us/en/software/junos/multicast-l2/topics/topic-map/layer-2- protocol-tunneling.html

NEW QUESTION 34
You have configured 802.1X single supplicant mode on the access switch. The VoIP phone does not support 802.1X authentication.

Referring to the exhibit, which statement is true?

MAC bypass must be configured for the VoIP phone for this solution to work.

Authentication must be changed to multiple supplicant mode for this solution to work.

The VoIP phone will be able to communicate over the network after the workstation authenticates.

The VoIP phone will not be able to communicate over the network.

NEW QUESTION 35
You recently committed a change to a router to reject OSPF routes sourced from area 10.
However, you are still seeing area 10 routes in the routing table. Referring to the exhibit, which statement is correct?

The OSPF protocol is first matched by find-ospf and accepted.

The routes only timeout after 24 hours.

The routes remain in the table until the device is rebooted.

The routes remain in the table until the routing daemon is restarted.

Once a route is accepted, no other terms in the routing policy are evaluated.

NEW QUESTION 36

NEW QUESTION 39
Which address range is used for source-specific multicast?

239.0.0.0/8

233.0.0.0/8

232.0.0.0/8

224.2.0.0/16

The address range 232.0.0.0/8 is reserved for Source-Specific Multicast (SSM). This range is specifically allocated for SSM where data is sent from a specific source to the receivers.
References:
* Source-Specific Multicast (SSM) Overview, RFC 4607

NEW QUESTION 40
Your network has an unmanaged switch between the hosts and your EX Series switch. After the traffic enters the EX Series switch, each host must be on a separate VLAN.
How would you accomplish this task?

Configure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs.

Configure an output firewall filter on interface ge-0/0/1 to match the destination MAC or IP address of the hosts to assign the VLANs.

Configure interface ge-0/0/3 to a mode trunk to assign the VLANs.

Configure VSTP on interface ge-0/0/1 to assign the VLANs.

To ensure that each host is placed on a separate VLAN when using an unmanaged switch between the hosts and the EX Series switch:
* Configure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs:
* By configuring an input firewall filter, you can match the source MAC or IP address of incoming traffic and assign the appropriate VLAN based on these criteria.
* This method ensures that even though the switch between hosts and EX Series is unmanaged, VLAN assignments are still properly enforced at the EX Series switch.
Configuration Example:
set firewall family ethernet-switching filter VLAN-assignment term VLAN100 from source-mac-address xx:xx:xx:xx:xx:xx set firewall family ethernet-switching filter VLAN-assignment term VLAN100 then vlan-assignment vlan 100 set firewall family ethernet-switching filter VLAN-assignment term VLAN200 from source-mac-address yy:yy:yy:yy:yy:yy set firewall family ethernet-switching filter VLAN-assignment term VLAN200 then vlan-assignment vlan 200 set firewall family ethernet-switching filter VLAN-assignment term VLAN300 from source-mac-address zz:zz:zz:zz:zz:zz set firewall family ethernet-switching filter VLAN-assignment term VLAN300 then vlan-assignment vlan 300 set interfaces ge-0/0/3 unit 0 family ethernet-switching filter input VLAN-assignment References:
* The command references from “Useful Juniper Commands.txt” and network configuration guides provide details on firewall filters and VLAN assignments.
