It accepts the route and adds the local AS to the AS_PATH.

It rejects the route by default.

It replaces the received AS_PATH with the local AS.

It lowers the preference of the route.

QUESTION 58

accept-remote-nexthop

multihop

advertise-inactive

multipath

QUESTION 59

Type 1

Type 5

Type 7

Type 9

QUESTION 60
Exhibit:

During an outage, you review the status of the Q-in-Q implementation on VLAN 300. Referring to the exhibit, what would be the cause of the outage?

The S-VLAN is disabled

The VLAN range overlaps

The C-VLANs are disabled.

There are no active ports

QUESTION 61
Which three statements are true about strict-high priority queues? (Choose three.)

In systems that support strict-high and high priority queues, traffic in the strict-high queue is completely emptied, and then high priority queue traffic is processed.

In systems that support strict-high and high priority queues, traffic in these two priorities is processed in a round-robin fashion.

When a strict-high queue goes into negative credits, it will maintain a strict DSCP marking.

When a strict-high queue can never go into negative credits and will always transmit the traffic in the queue.

In systems that support multiple strict-high priority queues, traffic in the strict-high queue is processed in a round-robin fashion.

QUESTION 62
Click the Exhibit button.

You are configuring multicast routing in a Juniper enterprise network using PIM sparse mode (PIM SM). The network includes multiple routers and R1 is designated as the rendezvous point (RP). You want to ensure that multicast traffic from the sources reach receivers across the network.
Referring to the exhibit, which two configuration elements are required on R2 to ensure proper multicast forwarding? (Choose two.)

Configure MSDP between R2 and the RP.

Enable PIM on interfaces participating in multicast routing.

Enable IGMP on interfaces connected to multicast receivers.

Configure static multicast routes using set routing-options static route for each multicast group.

QUESTION 63
Exhibit:

Referring to the exhibit, which two statements are true regarding Q-in-Q tunneling? (Choose two.)

The C-VLAN traffic will be encapsulated with an outer VLAN tag of 150.

The C-VLANs 100-200 will be sent as the inner VLAN tag.

The C-VLAN 150 will be sent as the inner VLAN tag.

The C-VLAN traffic will be encapsulated with an outer VLAN tag of 10.

QUESTION 64
Which two statements are correct when using the no-loss forwarding class? (Choose two.)

Use the default scheduler map.

Use forwarding class sets.

Use priority-based now control.

Use the default drop profile.

QUESTION 65
You are evaluating a BGP routing policy that has a route-filter clause that includes its own action (e.g., accept) within the filter block. The policy is also using a then clause. Which statement is correct in this scenario?

The policy ignores the filter action and defers to the then clause.

The filter action is treated as a suggestion and combined with the then action.

The filter action is applied only if no then action is defined.

The filter’s accept action executes immediately upon matching and the then clause is ignored.

QUESTION 66
In the context of Junos, what is the purpose of the ‘multicast’ routing-options configuration hierarchy?

To enable multicast routing protocols such as PIM or MSDP

To specify static multicast routes

To configure multicast rate limiting

QUESTION 67
Which two statements correctly describe how EX Series switches use captive portal for Layer 2 authentication? (Choose two.)

The captive portal is the default Layer 2 authentication method that is applied before other methods such as 802.1X or MAC RADIUS.

The captive portal authentication allowlist works for devices that do not have HTTP capabilities.

The captive portal is configured on Layer 3 interfaces and does not participate in Layer 2 authentication on EX Series switches.

The captive portal is used as a fallback mechanism for clients that fail 802.1X or MAC RADIUS authentication.

QUESTION 68
You have configured a multi-area OSPF network. You want to limit the effect that network changes in other areas affect Area 1.
What can be done to accomplish this task?

Configure overload on the area 1 ABR.

Use the [area-range] statement at the area 1 ABR to summarize routes that go to other areas.

Increase the value of the [protocols ospf spf-options delay].

Configure Area 1 as a stub area with no summaries.

QUESTION 69
Which two telephony features are available on EX Series switches? (Choose two.)

voicemail forwarding and retrieval

power over Ethernet

call routing

class of service
