Configure and verify IPv4 addressing and subnetting

A NOC Engineer is investigating a routing failure between two branch offices. Branch A uses 10.16.32.0/19 and Branch B uses 10.16.64.0/19. A new temporary site was provisioned with the IP block 10.16.48.0/20 and connected to the core router, causing Branch A to lose partial connectivity.

The engineer reviews the core routing table:

Core-Router# show ip route
C  10.16.32.0/19 is directly connected, GigabitEthernet0/1
C  10.16.64.0/19 is directly connected, GigabitEthernet0/2
S  10.16.48.0/20 [1/0] via 10.0.0.2, Tunnel0

Which two statements accurately describe the subnet overlap fault and its diagnostic impact? (Choose 2.)
