Question 290
A network upgrade at Granite Works has two requirements: (1) enable single-area OSPF on matching IPv4 interfaces, and (2) distinguish static route entries from learned routes. Select TWO actions that together satisfy both outcomes.
Explanation
Correct Answers
Correct for outcome (1): OSPF network statements select interfaces for the specified area using address and wildcard matching. The other outcome needs its separate action.
Correct for outcome (2): Cisco IOS marks configured static routes with S in show ip route. It complements the first required control.
Incorrect Answers
Not selected: Use ipv6 route ::/0 with outgoing interface and link-local next hop is for configure an IPv6 default route over a known link-local next hop. The egress interface is required to disambiguate a link-local next-hop address. This is outside the two requested outcomes.
Not selected: Compare AD for identical prefixes before protocol-specific metrics is for avoid comparing routing protocol metrics across unrelated protocols. OSPF and EIGRP metrics are not directly comparable scales across protocols. This is not one of the two required changes.
Not selected: Configure router-id under the OSPF process and restart the process when required is for set an OSPF router ID explicitly to avoid unexpected election. An explicitly configured 32-bit router ID has priority over automatic loopback/interface selection. This does not provide either of the two specified controls.
