NEW QUESTION 58
Which two statements are correct about generated routes? (Choose two.)

Generated routes require a contributing route.

Generated routes show a next hop in the routing table.

Generated routes appear in the routing table as static routes

Generated routes cannot be redistributed into dynamic routing protocols.

A is correct because generated routes require a contributing route. A contributing route is a route that matches the destination prefix of the generated route and has a valid next hop. A generated route is only installed in the routing table if there is at least one contributing route available. This ensures that the generated route is reachable and useful. If there is no contributing route, the generated route is not added to the routing table.
B is correct because generated routes show a next hop in the routing table. A generated route inherits the next hop of its primary contributing route, which is the most preferred route among all the contributing routes. The next hop of the generated route can be either an IP address or an interface name, depending on the type of the contributing route. The next hop of the generated route can also be modified by a routing policy.

NEW QUESTION 59
You are deploying an EX Series switch with a Wi-Fi access point. The access point needs all untagged traffic to use a specific VLAN. In this scenario, which feature should you enable on the switch port?

flexible VLAN tagging

voice VLAN

VLAN tagging

native VLAN

NEW QUESTION 60
Exhibit

You are a network operator troubleshooting BGP connectivity.
Which two statements are correct about the output shown in the exhibit? (Choose two.)

Peer 10.32.1.2 is configured for AS 63645.

The BGP session is not established.

The R1 is configured for AS 65400.

The routers are exchanging IPv4 routes.

Explanation
Option B suggests that the BGP session is not established. This is correct because in the output, the state of the BGP session is shown as “Idle”. In BGP, an “Idle” state means that the BGP session is not currently established1.
Option C suggests that R1 is configured for AS 65400. This is also correct because in the output, it’s shown that the local AS number is 654001. The local AS number represents the Autonomous System (AS) number of the router on which you’re checking the BGP session1.

NEW QUESTION 61
Which statement correctly describes the purpose of BPDU protection in Junos OS?

It prevents the local switch from processing configuration changes.

It disables a port that receives a BPDU when the port is configured as an edge port, preventing unauthorized switches from participating in the spanning tree.

It is used only on trunk ports carrying multiple VLANs.

It replaces the need for root protection.

BPDU protection is applied to edge ports (ports expected to connect only to end hosts) to guard against unauthorized or rogue switches being connected. If a BPDU is received on a protected edge port, the port is automatically disabled, preventing potential spanning tree topology changes caused by unauthorized devices.

NEW QUESTION 62
Referring to the exhibit, what will be the IS-IS adjacency result of the configurations?

No IS-IS adjacencies will form.

A level 1 and level 2 IS-IS adjacency will form.

A level 2 IS-IS adjacency will form.

A level 1 IS-IS adjacency will form.

NEW QUESTION 63
Which statement is correct about the storm control feature?

The storm control feature is enabled in the factory-default configuration on EX Series switches.

The storm control feature requires a special license on EX Series switches.

The storm control feature is not supported on aggregate Ethernet interfaces.

The storm control configuration only applies to traffic being sent between the forwarding and control plane.

Option A is correct. The storm control feature is enabled in the factory-default configuration on EX Series switches12. On EX2200, EX3200, EX3300, EX4200, and EX6200 switches, the factory default configuration enables storm control for broadcast and unknown unicast traffic on all switch interfaces2. On EX4300 switches, the factory default configuration enables storm control on all Layer 2 switch interfaces1.
Option B is incorrect. The storm control feature does not require a special license on EX Series switches34.
Option C is incorrect. There’s no information available that suggests the storm control feature is not supported on aggregate Ethernet interfaces.
Option D is incorrect. The storm control configuration applies to traffic at the ingress of an interface5, not just between the forwarding and control plane.

NEW QUESTION 64
You are receiving multiple BGP routes from an upstream neighbor and only want to advertise a single summarized prefix to your internal OSPF neighbors. This route should only be advertised when you are receiving these BGP routes from this neighbor.
In this scenario, which type of route should you create?

aggregate route

static route using the resolve feature

generate route

static route using qualified next hops

Explanation
In this scenario, you should create an 1. Aggregate routes are used for advertising summarized network prefixes1. They help minimize the number of routing tables in an IP network by consolidating selected multiple routes into a single route advertisement1. This approach is in contrast to non-aggregation routing, in which every routing table contains a unique entry for each route1.
Therefore, option A is correct. Options B, C, and D are not correct because:
Static route using the resolve feature: This type of route uses the resolve feature to install a static route in the routing table only if a specific condition is met1. However, it does not provide the capability to summarize multiple routes into a single prefix.
Generate route: This type of route generates a route that is always present in the routing table and can be used to summarize routes. However, it does not have the capability to only advertise the route when specific BGP routes are being received from a neighbor1.
Static route using qualified next hops: This type of route allows for the specification of multiple next-hop addresses for a static route1. However, it does not provide the capability to summarize multiple routes into a single prefix.

NEW QUESTION 65
R1 was started at 4:00 PM. R2 and R3 were started at 6:00 PM. R4 was started at 10:00 PM. All routers are in Area 0 and there are no point-to-point links.
Referring to the exhibit, which router is the designated router?

NEW QUESTION 66
Exhibit.

You want to verify prefix information being sent from 10.36.1.4.
Which two statements are correct about the output shown in the exhibit? (Choose two.)

The routes displayed have traversed one or more autonomous systems.

The output shows routes that were received prior to the application of any BGP import policies.

The output shows routes that are active and rejected by an import policy.

The routes displayed are being learned from an I BGP peer.

A). The routes displayed have traversed one or more autonomous systems. True. The AS path attribute shows AS numbers (e.g., 65401 65520.), indicating the route ‘ s traversal through various autonomous systems. D.
The routes displayed are being learned from an IBGP peer. True. The absence of the ‘ * > i ‘ marker before the prefixes indicates they are being learned from an IBGP peer. Therefore, the correct statements are A. The routes displayed have traversed one or more autonomous systems. and D. The routes displayed are being learned from an IBGP peer.

NEW QUESTION 67
You are using tunnels in your network. It is important that the routes be specific enough to ensure that the tunnels are established. You need to prevent a route that is new to the network from being used. In this scenario, which type of route should be used?

multicast

aggregate

static

anycast

NEW QUESTION 68
Which command solves the error that you see in the exhibit?

delete ge-0/0/2 unit 0 family ethernet-switching vlan members default

set ge-0/0/2 unit 0 family ethernet-switching vlan members [default v11]

delete ge-0/0/2 unit 0 family ethernet-switching vlan members all

set ge-0/0/2 unit 0 family ethernet-switching vlan members all

The error in the exhibit occurs because an access interface can only be a member of one VLAN, but it is currently configured with the “default” VLAN and is trying to be added to VLAN “v11.” To resolve the issue, the correct command is:
delete ge-0/0/2 unit 0 family ethernet-switching vlan members default
This command removes the interface from the “default” VLAN, allowing it to be part of VLAN
“v11” as intended.

NEW QUESTION 69
Your switches are managed using Junos Space Network Director. You want to secure the switches using a Network Director filter profile. A filter profile containing one term shown in the exhibit is deployed to ports on managed devices.

Which traffic will be accepted by the filter?

All traffic will be accepted.

Traffic containing a source MAC of 02:85:05:00:00:00/24 will be accepted.

Traffic containing a destination MAC of 02:85:05:00:00:00/24 will be accepted.

No traffic will be accepted.

NEW QUESTION 70
Which two statements about the firewall filter terms shown in the exhibit are true? (Choose two.)

Traffic that matches the fromstatement in term oneis discarded.

All traffic not matching the fromstatement in term oneis accepted by term two.

Traffic that matches the fromstatement in term oneis accepted.

Traffic matching the fromstatement in term twois logged.

NEW QUESTION 71
Which two BGP attributes must be supported by all BGP implementations and must be included in every update? (Choose two.)

AS path

MED

next hop

community

Explanation
BGP attributes are properties that BGP uses for route advertisement, path selection, and loop prevention1. There are four categories of BGP attributes123:
Well-known mandatory: Must be recognized by all BGP routers, present in all BGP updates, and passed on to other BGP routers123.
Well-known discretionary: Supported by all BGP implementations, and are optionally included in BGP updates1.
Optional transitive: May not be supported by all implementations of BGP1.
Optional non-transitive: May not be supported by all implementations of BGP1.
The well-known mandatory attributes must be supported by all BGP implementations and must be included in every update123. These include the AS path and next hop attributes23. Therefore, options A and C are correct.

NEW QUESTION 72
In addition to the MAC addresses, what information is stored in the bridging table? (Choose two.)

ether type details

interface details

preamble of Ethernet packet

MAC learned time

The bridging table is a data structure that stores the MAC addresses and the associated interface details and MAC learned time for each MAC address. The bridging table is used by the switch to forward frames based on the destination MAC address. The ether type details and the preamble of Ethernet packet are not stored in the bridging table, as they are not relevant for the switching process. References:
