A network administrator needs to understand why endpoints that use Switch-3 as their default router can no longer reach some resources. The exhibit shows the OSPF link state database (LSDB) on Switch-1 when the OSPF solution was first deployed and the current LSDB.
What is a likely place to find the issue?

• A.in the Switch-3 OSPF Area 1 configuration settings
• B.in the connectivity status between Switch-3 and Switch-1
• C.in the Switch-1 OSPF Area 1 configuration settings
• D.in the connectivity status between Switch-1 and Switch-2

An administrator created a backplane stack with the plug-and-play method, and did not alter the default backplane stacking settings. Later, two backplane stacking links failed, as shown in the exhibit.
What happens to the backplane stack after the failures?

• A.The standby becomes the commander of its fragment, which remains active. The fragment with the commander becomes inactive.
• B.The fragment that contains the commander remains active, and the fragment with the standby member is disabled.
• C.The standby becomes the commander of its fragment. Both fragments remain active and operate at both Layer 2 and Layer 3.
• D.The fragment that contains the commander operates at Layer 2 and layer 3, and the other fragment operates at layer 2 only.
