Question #1
Which two events cause a static route to be removed from a routing table? (Choose two.)
Select 2 answers.
Please select an optionIncorrectCorrect answer: A, B
A static route stays in the routing table until the administrator deletes it from the configuration or its next hop becomes unreachable, for example when the outbound interface goes down. Static routes never age out and are not affected by distant host reachability.
Was this answer correct?Question #2
You have configured an MPLS LSP that begins on R1 and terminates on R5 using the Junos default settings. Referring to the exhibit, which router will perform only label swap operations?
Please select an optionIncorrectCorrect answer: B
R1 is the ingress router and pushes the label, R4 is the penultimate hop and pops it because Junos enables penultimate hop popping by default, and R5 is the egress. R3 is the transit router that only swaps labels.
Was this answer correct?Question #3
You must ensure that your routing platform with redundant REs continues to forward packets, even if one RE fails. Which technology would you use to accomplish this task?
Please select an optionIncorrectCorrect answer: D
GRES keeps the backup Routing Engine synchronized with chassis and interface state, so when the primary RE fails the backup takes over and the PFE keeps forwarding packets. NSB covers Layer 2 protocol state, LAG protects links and BFD only detects failures.
Was this answer correct?Question #4
What is the default export behavior of IS-IS in the Junos OS?
Please select an optionIncorrectCorrect answer: C
The default IS-IS export policy in Junos rejects everything; only directly connected interfaces enabled under [edit protocols isis] are advertised. Redistributing other routes requires an explicit export policy.
Was this answer correct?Question #5
What are three extension headers supported by IPv6? (Choose three.)
Select 3 answers.
Please select an optionIncorrectCorrect answer: A, B, E
IPv6 extension headers include hop-by-hop options, destination options, routing, fragment, authentication and ESP. Protocol and header checksum are IPv4 base-header fields, not IPv6 extension headers.
Was this answer correct?Question #6
Referring to the exhibit, which protocol would automatically create a full mesh of label-switched paths between MPLS-enabled routers?
Please select an optionIncorrectCorrect answer: A
LDP is topology-driven: it follows the IGP (OSPF area 0.0.0.0 here) and automatically exchanges labels with every neighbor, building a full mesh of LSPs between all LDP-enabled routers. RSVP LSPs must be configured individually; BGP and BFD do not signal LSPs.
Was this answer correct?Question #7
In IS-IS, what would you use to control which external routes are installed in the routing table?
Please select an optionIncorrectCorrect answer: B
In Junos an IS-IS import policy controls which routes learned by IS-IS (external routes) are installed in the routing table. Export policies control what is advertised into IS-IS, and route preference and metrics do not filter routes.
Was this answer correct?Question #8
What information is determined by using the AS path attribute included in the BGP update message? (Choose two.)
Select 2 answers.
Please select an optionIncorrectCorrect answer: B, C
AS_PATH lists the autonomous systems a route has traversed. A router that sees its own AS in the path detects a loop and rejects the route, and a shorter AS path is preferred during path selection. It says nothing about next-hop router counts or the origin code.
Was this answer correct?Question #9
Exhibit: Referring to the exhibit, R1 is advertising prefix 203.0.113.0/24 to R2 over EBGP. R2 is configured to advertise this prefix into IBGP. R3 receives the 203.0.113.0/24 route, however the route is hidden. Which configuration statement do you need to add to R2 to solve this problem?
Please select an optionIncorrectCorrect answer: B
R3 hides the route because its next hop is R1's EBGP address 172.16.10.1, which R3 cannot resolve. Adding then next-hop self to the export-to-ibgp policy makes R2 rewrite the next hop to its own address, which R3 can reach.
Was this answer correct?Question #10
You are using EBGP to connect to two upstream peers in the same AS. You want to make one of the links less preferred for traffic entering your network from the peer's AS. Which feature should you use to achieve this goal?
Please select an optionIncorrectCorrect answer: C
AS-path prepending lengthens the AS path advertised over one link, making that path less attractive to the peer AS and steering inbound traffic to the other link. Local preference only influences outbound path selection within your own AS.
