Sample Questions
Choose an answer and explore the explanation to see how practice works.
During a Junos OS v25.2 deployment for a university research network, IPv4 and IPv6 services are both in scope. Two Junos OS v25.2 routers form OSPFv2 adjacency on a link, but OSPFv3 remains ExStart and both sides show different interface instance settings. The change record is tagged for OSPFv3 IPv6 adjacency mismatch. Which action should the engineer take first?
During a Junos OS v25.2 deployment for a regional retailer, stores connect through low-bandwidth WAN circuits. Two data centers need resilient ASM RP service using the same RP address, and sources may register at either site. The change record is tagged for Anycast RP MSDP. Which diagnosis or configuration change best addresses the issue without creating a broader control-plane side effect?
During a Junos OS v25.2 deployment for a regional retailer, stores connect through low-bandwidth WAN circuits. An operations team must permit only routes originated by a partner AS, not routes merely transiting that AS. The change record is tagged for BGP AS path regex. Which action should the engineer take first?
During a Junos OS v25.2 deployment for a financial trading floor, rollback must preserve existing sessions. A remote site must inject a local static route into OSPF, but security policy prohibits Type 5 LSAs inside that area. The change record is tagged for OSPF NSSA external reachability. Which interpretation is most accurate?
During a Junos OS v25.2 deployment for a public sector data center, audit evidence must match operational state. A core router is being upgraded and must remain reachable for management while no longer attracting transit traffic. The change record is tagged for OSPF overload during maintenance. Which action should the engineer take first?
