The answer is that the BGP session to 192.168.1.3 has been manually disabled, as indicated by the “Idle (Admin)” state in the show ip bgp summary output. This occurs because the neighbor shutdown command was applied under the BGP configuration for 192.168.1.3, placing the session into an administratively down condition where no messages are sent or received—note the zero MsgRcvd and MsgSent values. On the ENCOR 350-401 exam, this output tests your ability to distinguish between a normal Idle state (which might indicate a connectivity issue) and the explicit “(Admin)” flag, which is a common trap where candidates overlook the parenthetical label. The key takeaway is that “Admin” always means a manual shutdown, not a protocol failure. Memory tip: think of “Admin” as “Administratively Disabled”—if you see it, someone flipped the off switch.
350-401 SNMP and Syslog Practice Question
This 350-401 practice question tests your understanding of snmp and syslog. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A network engineer runs the following command on Router R2:
R2# show ip bgp summary
BGP router identifier 10.0.0.2, local AS number 65002
BGP table version is 10, main routing table version 10
4 network entries using 576 bytes of memory
4 path entries using 320 bytes of memory
3/2 BGP path/bestpath attribute entries using 456 bytes of memory
1 BGP AS-PATH entries using 24 bytes of memory
0 BGP route-map cache entries using 0 bytes of memory
0 BGP filter-list cache entries using 0 bytes of memory
BGP using 1376 total bytes of memory
BGP activity 6/2 prefixes, 6/2 paths, scan interval 60 secs
The BGP session to 192.168.1.3 is down due to a network failure.
Why wrong: The '(Admin)' flag indicates administrative shutdown, not a network failure.
B
The BGP session to 192.168.1.3 has been manually disabled.
The Idle state with '(Admin)' is a clear indication that the neighbor has been administratively shut down.
C
Router R2 has received 3 routes from 192.168.1.1.
Why wrong: The output shows PfxRcd=3 for 192.168.1.1, meaning 3 prefixes were received, but the question asks about the conclusion from the output, and the admin shutdown is the key observation.
D
The BGP table version is 10, meaning 10 routes are in the table.
Why wrong: The BGP table version is a version number, not a count of routes. The output shows 4 network entries.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The BGP session to 192.168.1.3 has been manually disabled.
The BGP summary shows two neighbors. The neighbor 192.168.1.1 (AS 65001) is up (02:15:30) and has sent 3 prefixes (PfxRcd=3). The neighbor 192.168.1.3 (AS 65003) is in Idle state with '(Admin)' indicating it has been administratively shut down (using 'neighbor shutdown' command). The Idle state with Admin flag means the neighbor is manually disabled.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

✗
The BGP session to 192.168.1.3 is down due to a network failure.
Why it's wrong here
The '(Admin)' flag indicates administrative shutdown, not a network failure.
✓
The BGP session to 192.168.1.3 has been manually disabled.
Why this is correct
The Idle state with '(Admin)' is a clear indication that the neighbor has been administratively shut down.
The output shows PfxRcd=3 for 192.168.1.1, meaning 3 prefixes were received, but the question asks about the conclusion from the output, and the admin shutdown is the key observation.
✗
The BGP table version is 10, meaning 10 routes are in the table.
Why it's wrong here
The BGP table version is a version number, not a count of routes. The output shows 4 network entries.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.

Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
OSPF neighbours must agree on key parameters.
Router ID selection can affect neighbour relationships and LSDB output.
OSPF cost influences the preferred path.
A route can appear in OSPF information but not become the installed route.
TExam Day Tips
→Check area mismatch first when OSPF adjacency fails.
→Review passive interfaces when a network is advertised but no neighbour forms.
→Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
Real-world example
How this comes up in practice
A network engineer at a university connects two campus buildings via a fibre link. Both routers run OSPF, but no adjacency forms — even though both routers can ping each other. The engineer finds one router is in area 0 and the other in area 1. OSPF adjacency requires matching area numbers, hello/dead timers, and network type. IP reachability alone is not enough.

What is the correct answer to this question?
The correct answer is: The BGP session to 192.168.1.3 has been manually disabled. — The BGP summary shows two neighbors. The neighbor 192.168.1.1 (AS 65001) is up (02:15:30) and has sent 3 prefixes (PfxRcd=3). The neighbor 192.168.1.3 (AS 65003) is in Idle state with '(Admin)' indicating it has been administratively shut down (using 'neighbor shutdown' command). The Idle state with Admin flag means the neighbor is manually disabled.
