You are using a Layer 3 VPN to connect two customer sites. The VPN routes for the customer networks appear as hidden in the bgp. 13vpn. o routing table on the PE routers.
What is causing this problem?

• A.There is a routing loop in the service provider backbone.
• B.The routes use overlapping IP addresses.
• C.There is not an established MPLS LSP between the two PE routers.
• D.Route targets are not configured.

Which statement is true regarding BGP FlowSpec?

• A.It uses a remote triggered black hole to protect a network from a denial-of-service attack.
• B.It is used to protect a network from denial-of-service attacks dynamically
• C.It verifies that the source IP of the incoming packet has a resolvable route in the routing table
• D.It uses dynamically created routing policies to protect a network from denial-of-service attacks

A packet is received on an interface configured with transmission scheduling. One of the configured queues In this scenario, which two actions will be taken by default on a Junos device? (Choose two.)

• A.The excess traffic will use bandwidth available from other queues
• B.The exceeding queue will be considered to have positive bandwidth credit
• C.The exceeding queue will be considered to have negative bandwidth credit.
• D.The excess traffic will be discarded

Exhibit

A network is using IS-IS for routing.
In this scenario, why are there two TLVs shown in the exhibit?

• A.Both IPv4 and IPv6 are being used in the topology
• B.The interface specified a metric of 100 for L2.
• C.Wide metrics have specifically been requested
• D.There are both narrow and wide metric devices in the topology

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

• B.OSPFv3 only supports IPv4.
• C.OSPFv3 is not backward compatible with IPv4
• D.OSPFv3 supports both IPv6 and IPv4, but not in the same routing instance.
