B.OSPF does not automatically advertise directly connected routes.
C.OSPF is used for routing information and neighbor discovery between multiple autonomous systems.
D.OSPF calculates routes using a distance vector algorithm

Question No : 4

You are troubleshooting a multicast deployment in a network. Some multicast groups operate in PIM-ASM mode and others operate in PIM-SSM mode.
While troubleshooting, you note the following:
- The network uses IGMPv2 for some segments and IGMPv3 for others.
- For group 232.1.1.1, receivers know the exact source IP of the multicast sender.
- For group 239.10.10.10, receivers do not know the source address in advance.
Which two statements correctly describe the operational differences between these two modes in Junos OS? (Choose two.)

A.PIM-SSM requires an RP for initial joins, whereas PIM-ASM can operate without one.
B.PIM-SSM relies on IGMPv3 to signal both the source and the group in the join message, bypassing the RP entirely.
C.PIM-ASM supports multiple active sources for a group without requiring receivers to know them in advance, whereas PIM-SSM requires explicit source knowledge.
D.In PIM-ASM, the DR first sends a PIM register message to the RP before switching to the shortest-path tree.

Your network receives the full Internet BGP routing table from two different ISPs. You want your local routers to use Provider A to forward all Internet traffic as long as Provider A is available.
Referring to the exhibit, which two actions would satisfy this requirement? (Choose two.)

A.Use a routing policy to set the local preference attribute value lower for the routes that are learned by R1.
B.Use a routing policy to set the local preference attribute value higher for the routes that are learned by R2.
C.Use a routing policy to set the local preference attribute value lower for the routes that are learned by R2.
D.Use a routing policy to set the local preference attribute value higher for the routes that are learned by R1.

Question No : 6

While deploying class of service on an EX Series switch, what are two aspects of the scheduler? (Choose two.)

A.It defines interface rate-limiting.
B.It defines a buffer size of the queue to which it is assigned.
C.It identifies the priority of the queue to which it is assigned.
D.It provides DiffServ code translation.

Question No : 7

Which statement about LLDP and LLDP-MED operations on EX Series devices is correct?

A.EX Series devices support LLDP-MED power negotiation, enabling dynamic allocation of PoE power based on endpoint device needs.
B.LLDP only operates on interfaces configured for Layer 2.
C.EX Series devices flood LLDP frames across a Layer 2 domain to calculate a network topology.
D.LLDP-MED focuses on discovering network connectivity devices like routers and switches

정답:

Question No : 8

You must implement EVPN signaling on an EX Series device that is configured with both underlay and overlay networks.
Which network protocol accomplishes this task?

A.OSPF underlay network
B.IS-IS underlay network
C.EBGP overlay network
D.MPLS overlay network

정답:

Question No : 9

You are enabling CoS throughout your enterprise network using the DSCP bits. You plan to use an MF classifier on all edge devices while using BA classifiers on all transit core devices.
In this scenario, what should you use to provide consistent handling of traffic?

A.You should implement rewrite rules on the core devices' ingress interfaces to rewrite the DSCP bits as it enters the device.
B.You should implement rewrite rules on the core devices' egress interfaces to rewrite the DSCP bits as it leaves the device toward other core devices.
C.You should implement rewrite rules on the edge devices' egress interfaces to rewrite the DSCP bits as it leaves the device toward the core.
D.You should implement rewrite rules on the edge devices' ingress interfaces to rewrite the DSCP bits as it enters the device.

Question No : 10

You are deploying a new campus switching environment using Ex Series switches. This new environment includes IP phones requiring Power over Ethernet (PoE) and end-user client PCs attached to a single switch port that will be configured with 802.1X authentication.
Considering the default configuration on an EX Series access switch and the configuration requirements to support this deployment, which two statements are correct? (Choose two.)

A.Configuration for LLDP and LLDP-MED on all relevant access ports must be added.
B.Configuration for 802.1X on all relevant access ports must be added.
C.Configuration for the voice VLAN for all relevant access ports must be added.
D.Configuration for PoE on all relevant access ports must be added.

Question No : 11

Which two statements are correct when using the no-loss forwarding class? (Choose two.)

A.Use the default scheduler map.
B.Use the default drop profile.
C.Use forwarding class sets.
D.Use priority-based flow control.

Question No : 12

Your OSPF network consists of a mix of 1GbE and 10GbE interfaces. By default, all interfaces have the same cost in your OSPF network You are asked to ensure that the 10GbE interfaces are more preferred when available.
In this scenario, which two statements would accomplish this behavior? (Choose two.)

A.You should manually assign the interface metric for each 1GbE interface to be higher than the 10GbE interfaces in your OSPF network.
B.You should define the reference bandwidth as 10G, which will assign the 1GbE interfaces a higher cost.
C.You should manually assign the interface metric for each 10GbE interface to be higher than the 1GbE interfaces in your OSPF network.
D.You should define the reference bandwidth as 1G, which will assign the 1GbE interfaces a higher cost.

Question No : 13

You have two multicast receivers connected to the same VLAN. You notice that the switch that they are connected to is forwarding multicast traffic out of all the ports in the same VLAN, instead of just the two ports for the connected multicast receivers.
In this scenario, what would you configure to optimize multicast forwarding?

A.IRB interface
B.IGMP snooping
C.promiscuous mode
D.spanning tree

Question No : 14

Click the Exhibit button.
You configured MVRP in your Layer 2 network using the configuration shown in the exhibit. You verified that the appropriate VLANs are configured and applied on the two access switches. You are using RSTP as your loop prevention mechanism. Unfortunately, the users are not able to communicate with their corresponding server attached to the Access-2 switch.
In this scenario, what should you do to solve this problem?

A.Configure VSTP instead of RSTP as your loop-prevention mechanism.
B.Configure the ge-0/o/16.0 interface on the Core-1 switch under MVR
C.Configure the access interfaces on the Access-1 switch under MVR
D.Configure the access interfaces on the Access-2 switch under MVR
