BGP

An administrator wants to modify the Local Preference attribute for all routes received from a specific external BGP peer. Where must this policy be applied in Junos?

Which TWO characteristics describe eBGP compared to iBGP? (Choose two)

Which THREE statements describe the role and function of the BGP Router ID? (Choose three)

During troubleshooting of a flapping BGP session, you notice BGP Notification messages being sent. Which BGP message type is responsible for tearing down a session due to an error condition?

A Juniper router is configured with a BGP peer group that includes multiple neighbors. You want to apply a policy to all neighbors in the group that sets the next-hop to a specific address for all routes received from them. Which configuration statement should you use?

What is the purpose of the BGP Keepalive message and what is its default interval in Junos?

You are a network administrator for a company using Juniper EX Series switches. You have an iBGP session between two routers in the same AS. You notice that routes learned from one iBGP peer are not being advertised to another iBGP peer. What is the default behavior of iBGP that explains this?

An administrator configures a BGP policy to reject routes with an AS_PATH containing a specific AS number. Which match condition in a Junos routing policy is used to evaluate the AS_PATH?

Which BGP message type is responsible for negotiating session parameters, including autonomous system numbers, hold times, and BGP identifiers during session establishment?

Which TWO BGP message types are responsible for maintaining session state or reporting errors without carrying routing information? (Choose two)

You are configuring a new eBGP session between two Juniper routers in different autonomous systems. The physical link is up and you can ping the remote interface, but the BGP session remains in the Active state. Reviewing the configuration, you notice that the neighbor statement on both routers specifies the loopback address of the peer, but no additional configuration is present. What is the most likely cause of the problem?

While examining a BGP routing table, you notice a route with an ORIGIN attribute set to 'Incomplete'. What does this indicate about the origin of the route?

An engineer is troubleshooting a BGP session between two routers and notices that the connection is stuck in the Active state. What does the Active state indicate about the BGP finite state machine?

A Junos router is configured as a BGP route reflector. It learns a route from a client and reflects it to a non-client and another client. Which attribute does the route reflector modify or add to prevent routing loops?

You are configuring a BGP session between two Juniper routers. You want to ensure that the session can be established and that routes are exchanged correctly. Which two statements are true about BGP message types? (Choose two.)

Which TCP port is used by BGP to establish communication between peers?

A network administrator needs to modify the Local Preference path attribute for all routes received from a specific external BGP peer using a routing policy on Junos. Under which configuration hierarchy should the routing policy be applied?

What is the primary function of the BGP OPEN message?

Which THREE actions occur when a BGP speaker receives a Notification message from a peer? (Choose three.)

You are running BGP between two routers. One router has a 4-byte ASN (e.g., ASN 65536). The remote router only supports 2-byte ASNs. How does BGP handle this compatibility issue?

Which TWO statements describe characteristics of BGP path attributes? (Choose two.)

You need to ensure that BGP sessions fail over within sub-second intervals if a link degrades or goes down. Which protocol should you integrate with BGP on your Junos router?

You are configuring BGP on a Juniper SRX Series firewall. You want to influence inbound traffic from an eBGP peer for a specific prefix. You have applied an export policy that prepends your AS multiple times. Which two statements are true about AS path prepending in this scenario? (Choose two.)

An engineer must inspect the BGP state and verify the received prefix counts from a specific neighbor on an MX Series router. Which operational command should be used?

An engineer needs to verify which BGP routes are currently installed in the forwarding table (FIB). Which command should be used?

A BGP speaker receives an UPDATE message containing a malformed attribute. According to BGP specifications, which action does the receiving router take?

Which TWO statements are true regarding BGP communities in Junos? (Choose two)

Which TWO actions occur when a Junos BGP routing policy includes the 'next policy' action? (Choose two)

While reviewing BGP updates, you notice an attribute type code of 3 with a value representing an IP address. Which well-known mandatory path attribute is this?

Which TWO statements accurately describe the behavior of the BGP AS_PATH attribute? (Choose two)

You need to configure authentication for a BGP peering session on a Junos device to prevent spoofing attacks. Where is the MD5 authentication key configured?

An administrator needs to verify the exact BGP timers negotiated with an eBGP peer on a Junos device. Which operational command should be used?

Which THREE attributes are optional transitive BGP path attributes? (Choose three)

An administrator wants to gracefully restart a BGP routing daemon without dropping the underlying TCP session or causing traffic loss. Which Junos feature should be enabled?
