Question#91

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 existing branch office as a temporary measure. The new branch office is assigned to 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
