NEW QUESTION 19
Exhibit

You are receiving the BGP route shown in the exhibit from four different upstream ISPs.
Referring to the exhibit, which ISP will be selected as the active path?

ISP1

ISP 3

ISP 4

ISP 2

NEW QUESTION 20
Exhibit.

You have configured the four EX Series switches with RSTP, as shown in the exhibit. You discover that whenever a link between switches goes up or down, the switches take longer than expected for RSTP to converge, using the default settings.
In this scenario, which action would solve the delay in RSTP convergence?

The hello-time must be increased.

The force-version must be removed.

The bridge priority for EX-4 must be set at 4000.

The max-age must be increased to 20

NEW QUESTION 21
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.

NEW QUESTION 22
You deployed a new EX Series switch with DHCP snooping enabled and you do not see any entries in the snooping databases for an interface. Which two Juniper configurations for that interface caused this issue?
(Choose two.)

The interface is configured as a disabled port.

MAC limiting is enabled on the interface.

The interface is configured as a trunk port.

Dynamic ARP inspection is enabled on the interface.

NEW QUESTION 23
Two routers share the same highest priority and start time.

In this situation, what is evaluated next when determining the designated router? The router with the lowest router ID become the DR.

The router with the highest router ID becomes the DR

The routers perform another DR election.

The router with the highest MAC address become the DR

NEW QUESTION 24
Exhibit.

What is the management IP address of the device shown in the exhibit?

10.210.20.233

172.23.12.100

128.0.0.1

172.23.11.10

NEW QUESTION 25
You have two OSPF routers forming an adjacency. R1 has a priority of 32 and a router ID of 192.168.1.2. R2 has a priority of 64 and a router ID of 192.168.1.1. The routers were started at the same time and all other OSPF settings are the default settings.
Which statement is correct in this scenario?

At least three routers are required for a DR/BDR election

Router IDs must match for an adjacency to form.

R2 will be the BDR.

R1 will be the BDR.

NEW QUESTION 26
Which statement about aggregate routes is correct?

Aggregate routes can only be used for static routing but not for dynamic routing protocols.

Aggregate routes are automatically generated for all of the subnets in a routing table.

Aggregate routes are always preferred over more specific routes, even when the specific routes have a better path.

Aggregate routes are used for advertising summarized network prefixes.

NEW QUESTION 27
Which two statements about redundant trunk groups on EX Series switches are correct? (Choose two.)

Redundant trunk groups use spanning tree to provide loop-free redundant uplinks.

Redundant trunk groups load balance traffic across two designated uplink interfaces.

Layer 2 control traffic is permitted on the secondary link.

If the active link fails, then the secondary link automatically takes over.

NEW QUESTION 28
Exhibit.

Why is this OSPF adjacency remaining in this state?

A subnet mask mismatch exists between the OSPF neighbors.

An MTU mismatch exists between the OSPF neighbors.

A hello interval mismatch exists between the OSPF neighbors.

An area ID mismatch exists between the OSPF neighbors

NEW QUESTION 29
You need to configure a LAG between your switches. In this scenario, which two statements are correct?
(Choose two.)

Duplex and speed settings are not required to match on both participating devices.

Duplex and speed settings are required to match on both participating devices.

Member links are not required to be contiguous ports.

Member links are required to be contiguous ports.

NEW QUESTION 30
Exhibit

Referring to the exhibit, which statement is correct?

The local device is using a bridge priority of 4k.

The root bridge is using a bridge priority of 4k.

The root bridge has not been elected for this RSTP topology.

The local device is the root bridge for this RSTP topology.

NEW QUESTION 31
What is the default keepalive time for BGP?

10 seconds

60 seconds

30 seconds

90 seconds

NEW QUESTION 32
Which statement is correct about IP-IP tunnels?

IP-IP tunnels only support encapsulating IP traffic.

IP-IP tunnels only support encapsulating non-IP traffic.

The TTL in the inner packet is decremented during transit to the tunnel endpoint.

There are 24 bytes of overhead with IP-IP encapsulation.

NEW QUESTION 33
A new network requires multiple topology support. You decide to use IS-IS in this situation. Which three protocol topologies are supported in this scenario? (Choose three.)

IPsec

anycast

IPv6

multicast

IPv4

NEW QUESTION 34
You are an operator for a network running 1S-IS. Two routers are failing to form an adjacency. What are two reasons for this problem? (Choose two.)

There are mismatched router IDs on the L2 routers.

There is no configured ISO address on any IS-IS interface.

There is a mismatched area ID between the L2 routers.

The family iso configuration is missing from the adjacency interface.
