A company is using OSPF between its HQ location and a branch office. HQ is assigned area 0 and the branch office is assigned area 1. The company purchases a second branch office, but due to circuit delays to HQ, it decides to connect the new branch office to the creating branch office as a temporary measure. The new branch office is assigned area 2. Which OSPF configuration enables all three locations to exchange routes?
A. The existing branch office must be configured as a stub area
B. A virtual link must be configured between the new branch office and HQ
C. A sham link must be configured between the new branch office and HQ
D. The new branch office must be configured as a stub area

Refer to the exhibit. Area 10 is a regular OSPF area and networks 10.1.1.0/24 and 172.16.1.0/24 are internal. Which design provides optimal routing between both networks when the link between routers C and E fails?
A. Move the link between routers C and D to area 10.
B. Create an OSPF virtual link between routers E and F.
C. Create a tunnel between routers E and F in area 10.
D. Make area 10 a not-so-stubby area.
