BGP Attribute Categories
There are four categories of BGP attributes:
Well-known mandatory:Recognized by all BGP peers, passed to all peers, and present in all Update messages. Well-known mandatory attributes include:- Next-hop- Origin- AS PATH Well-known discretionary:Recognized by all routers, passed to all peers, and optionally included in the Update message. Well-known discretionary attributes include:- Local Preference- Atomic Aggregate Optional transitive:Possibly recognized by BGP routers and passed to BGP peers. Optional transitive attributes are marked as partial when not recognized. Optional transitive attributes include:- Aggregator- Community Optional non-transitive:Possibly recognized by BGP routers but not passed to peers. Optional non-transitive attributes include:- Multi-exit discriminator (MED)- Originator ID- Cluster-ID

All devices in the network are configured correctly and the path requirements are valid.
Referring to the exhibit, which two statements are correct? (Choose two.)

The primary LSP will be signaled, and its state will be up.

The secondary LSP will not be signaled, and its state will be down.

The secondary LSP will be signaled, and its state will be up.

The primary LSP will not be signaled, and its state will be down.

According to the exhibit, the primary LSP is configured with a strict path via R2 to R4. Since the configuration shows valid next-hops and there is no indication of any issues, the primary LSP will be signaled and its state will be up. The secondary LSP with any-path is also configured and will be signaled as a backup; therefore, its state will be up as well, ready to take over if the primary fails.References:

NO.173 When would you use the qualified-next-hop statement with a static route?

You can use it to install the static route into different routing tables.

You can use it to send unwanted traffic to a null route.

You can use it to specify multiple next hops with different preferences.

You can use it to resolve the next hop if the next hop is not directly connected.

https://www.juniper.net/documentation/us/en/software/junos/static-routing/topics/topic-map/static-route-prefer-q Qualified next hops allow you to associate one or more properties with a particular next-hop address. You can set an overall preference for a particular static route and then specify a different preference for the qualified next hop. For example, suppose two next-hop addresses (10.10.10.10 and 10.10.10.7) are associated with the static route 192.168.47.5/32. A general preference is assigned to the entire static route, and then a different preference is assigned to only the qualified next-hop address 10.10.10.7. For example:
The qualified-next-hop statement with a static route is used to specify multiple next hops for a static route with different preferences (priorities). This allows for more granular control over the path selection process in the event that the primary next hop becomes unreachable.References:
Static Routes Overview, Juniper Networks Documentation

NO.174 Click the Exhibit button. From the output shown in the exhibit, what would happen to a packet destined for address 172.29.3.5?

The address is not in the aggregate range; the packet is sent to the Routing Engine.

The address is in the aggregate range; the packet will be silently dropped.

The address is not in the aggregate range; the packet will be forwarded.

The address is in the aggregate range; the packet will be dropped.

NO.175 Which configuration selling prohibits a static route from being redistributed by a dynamic routing protocol?

route-filter

no-readvertise

qualified-next-hop

passive

NO.176 You are asked to configure an LSP which uses the OSPF link state database for path computations. Which two statements are correct in this scenario? (Choose two.)

You must use the no-cspf parameter in the label-switched-path configuration.

Traffic engineering extensions ate enabled by default In OSPF.

Traffic engineering extensions are not enabled by default in OSPF.

You must use the policing parameter in the label-switched-path configuration.

The no-cspf command will activate usage of OSPF DB https://www.juniper.net/documentation/us/en/software/junos/ospf/topics/topic-map/configuring-ospf-support-for-traffic-engineering.html Not enabled by default for ospf

NO.177 The IPv6 Neighbor Discovery Protocol (NDP) performs the same function as which two IPv4 protocols? (Choose two.)

ICMP

ARP

DNS

DHCP

NO.178 Click the Exhibit button. Referring to the exhibit, what must be true of the vlan_100 bridge domain?

vlan_100 has at least one Ethernet interface assigned to it.

vlan_100 does not have an Ethernet interface assigned to it.

vlan_100 might have an active Ethernet interface assigned to it.

vlan_100 does not have an active Ethernet interface assigned to it.

NO.179 An OSPF router does not have a router ID configured. In this scenario, which statement is correct about the router ID?

The Junos OS will use the IP address assigned to the interface with the lowest MAC address.

A router ID will not be assigned until it is manually configured.

The Junos OS will use the IP address assigned to the loopback interface for the router ID.

The Junos OS will use the IP address assigned to the Interface with the highest priority.

The router identifier is used by BGP and OSPF to identify the routing device from which a packet originated. The router identifier usually is the IP address of the local routing device. If you do not configure a router identifier, the IP address of the first interface to come online is used. This is usually the loopback interface.
Otherwise, the first hardware interface with an IP address is used.

NO.180 You have been asked to provision a service provider’s network to accommodate Layer 3 VPNs as defined in RFC 4364.Which three tasks must be performed before the provider network is ready to carry VPN traffic? (Choose three.)

All Juniper Networks PE routers must be configured with an appropriate router-ID unique to the VPN.

All Juniper Networks PE routers must be configured with an appropriate route-target unique to the VPN.

All Juniper Networks PE routers must be configured with a routing-instance of type forwarding.

All Juniper Networks PE routers must be configured with a routing-instance of type vrf.

All Juniper Networks PE routers must be configured with a routing-instance containing the CE- facing interface.

NO.181 What are two methods for decreasing the size of an OSPF link-state database (LSDB)? (Choose two.)

Ensure that all routers on a shared segment are configured with a priority value of 0.

Use an interface type of p2p when possible.

Segment large groups of routers into areas.

Change a stub area to NSSA when possible.

NO.182 Which two high availability features preserve interface and kernel information during reconvergence? (Choose two.)

graceful restart (GR)

nonstop bridging (NSB)

nonstop active routing (NSR)

graceful Routing Engine switchover (GRES)

NO.183 Which statement is true about routing instances on Junos devices?

Routing information cannot be shared between routing instance.

Each routing protocol runs in a separate routing instance.

Junos device support only one routing instance.

Each routing instance is a unique grouping of routing tables, interfaces, and routing protocol parameters.

NO.184 What happens when a packet matches a static route with the next hop parameter set to reject?

The system silently drops the packet

An ICMP message is sent to the source and the packet is forwarded

An ICMP message is sent to the source and the packet is dropped

The packet is forwarded and the packet is marked as rejected in the header

NO.185 Exhibit

You confirm that the R2 and R3 routers are receiving a BGP route to the 203.0.113.0/24 network, but both routers display the route as hidden. Referring to the exhibit, which two actions solve this problem? (Choose two.)

Apply the routing policy on R1 as an import policy to the IBGP group.

Configure a routing policy on R1 that sets the next hop for the 203 0.113.0/24 BGP route to the IP address that R1 uses for IBGP peering.

Configure a routing policy on R1 that sets the next hop for the 203.0.113.0/24 BGP route to the IP address that R1 uses for EBGP peering.

Apply the routing policy on R1 as an export policy to the IBGP group.

B) Configure a routing policy on R1 that sets the next hop for the 203 0.113.0/24 BGP route to the IP address that R1 uses for IBGP peering. = configure a “then next-hop self” policy
