Free Juniper Service Provider Routing and Switching, Professional (JNCIP-SP) Exam JN0-663 Exam Practice Test

You are asked to configure a series of interface policers and firewall filters, which include policers, on the same device You must ensure that the two configuration methods do not conflict.What are two considerations when performing this task? (Choose two.)

• On inbound traffic, interface policers are applied before firewall filters.
• On inbound traffic, firewall filters are applied before interface policers.
• On outbound traffic, interface policers are applied before firewall filters.
• On outbound traffic, firewall filters are applied before interface policers.

Which two statements about virtual links are correct? (Choose two.)

• Virtual links are used for control plane traffic.
• Virtual links are point-to-point.
• Virtual links are excluded from SPF calculations.
• Virtual links are bidirectional.

Which two types of LSAs have an area scope? (Choose two)

• Type5
• Type 2
• Type 7
• Type 11

A customer recently migrated to IS-IS and is concerned about resource starvation when the routing protocol daemon (RPD) starts.To resolve this issue and protect R2 and R3, which feature should you implement?

• Deploy firewall filters to limit the prefix count in the route table
• Double the policy-options damping half-life timer to let the network settle.
• Use the forwarding-options ip-options-protocol-queue parameter to increase resources.
• Implement the overload bit and timer to signal service availability.

Why do jnterprovider option B VPNs scale better than interprovider option A VPNs?

• The ASBRs in interprovider option B VPNs only carry internal routes.
• The ASBRs in interprovider option A VPNs do not need per-VPN VRF tables.
• The ASBRs in interprovider option A VPNs only carry internal routes.
• The ASBRs in interprovider option B VPNs do not need per-VPN VRF tables.

The link between CE1 and PE1 has a history of flapping To avoid the impact that flapping causes to the network you decide to use route dampingWhich statement is correct in this scenario?

• Dampened routes decay at a sliding rate known as half-life
• Routes become dampened when the configured max-suppress value is reached
• Dampening is enabled on interfaces
• Dampened routes become active when their figure of merit drops below the reuse value.

You are establishing a Layer 3 VPN between two PE devices Currently you have a single internal IPv4 BGP peering between the PE devices. You must ensure that the IPv4 and IPv6 routes from both CE devices are exchanged between these sitesWhich two statements are correct in this scenario? (Choose two.)

• You must establish an IPv6 BGP peering between the two PEs
• You must enable the inet-vpn NLR on both PE devices.
• You must enable the inet6-vpn NLRI on both PE devices.
• You must enable IPv6 tunneling on the LSPs between the PE devices

What occurs when a router running IS-IS receives an LSP with the overload bit set?

• The LSP is not added to the link-state database.
• The LSP's metric will be set to 65535.
• The LSP is ignored during SPF calculation.
• The LSPs metric will be set to 16777215.

Which two statements are true about what a route reflector does by default when distributing routes it has received from reflector clients? (Choose two.)

• It changes the default BGP attributes to inform peers that it is a route reflector.
• It adds its cluster ID to the client-received routes.
• It sets the next hop of all routes to 'self' to prevent routing loops.
• It does not change any received BGP attributes.

Which two statements about IS-IS are correct? (Choose two.)

• Level 1 intermediate systems exchange routing information with Level 1 intermediate systems in other IS-IS areas.
• An IS-IS router sets the attached bit in the PDUs it sends to a Level 1 area to indicate that it is a backbone router.
• A Level 1 router can only form adjacencies with other Level 1 routers.
• Level 2 routers can form adjacencies with either Level 1 or Level 2 routers.
