Internet traffic from Site 2 takes the path of PE-2 -> PE-1 -> CE-1 -> PE-1 -> GW-1.

Q33. Which statement is true regarding BGP FlowSpec?

It uses a remote triggered black hole to protect a network from a denial-of-service attack.

It uses dynamically created routing policies to protect a network from denial-of-service attacks

It is used to protect a network from denial-of-service attacks dynamically

It verifies that the source IP of the incoming packet has a resolvable route in the routing table

Q34. When using OSPFv3 for an IPv4 environment, which statement is correct?

OSPFv3 only supports IPv4.

OSPFv3 supports both IPv6 and IPv4, but not in the same routing instance.

OSPFv3 is not backward compatible with IPv4

OSPFv3 supports IPv4 only on interfaces with family inet6 defined

Q35. Exhibit

You are attempting to summarize routes from the 203.0.113.128/25 IP block on R8 to AS 64500. You implement the export policy shown in the exhibit and all routes from the routing table stop being advertised.
In this scenario, which two steps would you take to summarize the route in BGP? (Choose two.)

Remove the from protocol bgp command from the export policy.

Add the set protocols bgp family inet unicast add-path command to allow additional routes to the RIB tables. –

Add the set routing-options static route 203.0.113.123/25 discard command.

Replace exact in the export policy with orlonger.

Q36. Exhibit

CE-1 and CE-2 are part of a VPLS called Customer1 No connectivity exists between CE-1 and CE-2. In the process of troubleshooting, you notice PE-1 is not learning any routes for this VPLS from PE-2, and PE-2 is not learning any routes for this VPLS from PE-1.

The route target must match on PE-1 and PE-2.

The route distinguisher must match on PE-1 and PE-2.

The instance type should be changed to I2vpn.

The no-tunnel-services statement should be deleted on both PEs.

Q37. Which three mechanisms are used by Junos platforms to evaluate incoming traffic for CoS purposes? (Choose three )

rewrite rules

behavior aggregate classifiers

traffic shapers

fixed classifiers

multifield classifiers

Q38. Which two statements are correct about reflecting inet-vpn unicast prefixes in BGP route reflection? (Choose two.)

Route reflectors do not change any existing BGP attributes by default when advertising routes.

A BGP peer does not require any configuration changes to become a route reflector client.

Clients add their originator ID when advertising routes to their route reflector

Route reflectors add their cluster ID to the AS path when readvertising client routes.

Q39. Exhibit

The environment is using BGP All devices are in the same AS with reachability redundancy Referring to the exhibit, which statement is correct?

RR1 is peered to Client2 and RR2

RR2 is in an OpenConfirm State until RR1 becomes unreachable.

Client1 is peered to Client2 and Client3.

Peering is dynamically discovered between all devices.

Q43. Exhibit

Referring to the exhibit, what do the brackets [ ] in the AS path identify?

They identify the local AS number associated with the AS path if configured on the router, or if AS path prepending is configured

They identify an AS set, which are groups of AS numbers in which the order does not matter

They identify that the autonomous system number is incomplete and awaiting more information from the BGP protocol.
