单选题Router R1 currently has no configuration related to IPv6 or IPv4. The following configuration exists in a planning document, intended to be used to copy/paste into Router R1 to enable OSPFv3 on interfaces F0/0 and S0/0/0. No other related configuration
题目
OSPF works on F0/0 and S0/0/0 without further configuration
OSPF works with the addition of one command: a no shutdown command in OSPF router configur ation modE
OSPF works with the addition of one command: an router - id command in OSPF router configuration modE
OSPFv3 needs at least two more configuration commands before it works on R1

Router R1 uses S0/0 to connect via a T/1 to the Frame Relay servicE. Five PVCs terminate on the serial link. Three PVCs (101, 102, and 103) are configured on subinterface S0/0.1, and one each (104 and 105) are on S0/0 .2 and S0/0.3. The configuration shows no configuration related to EIGRP WAN bandwidth control, and the bandwidth command is not configured at all.

- B、R1 limits EIGRP to around 250Kbps on DLCI 104
- C、R1 limits EIGRP to around 150Kbps on every DLCI
- D、R1 does not limit EIGRP because noWAN bandwidth control has been configured

An engineer has added the following configuration snippet to an implementation planning document. The configuration will be added to Router R1, whose Fa0/0 interface connects to a LAN to which Routers R2 and R3 also connect. R2 and R3 are already EIGRP neighbors with each of her. Assuming the snippet shows all commands on R1 related to EIGRP authentication, which answer lists an appropriate comment to be made during the implementation plan peer review?（） key chain fred key 3 key - string whehew interface fa0/0 ip authenticat ion key - chain eigrp 9 fred
- A、The configuration is missing one authentication - related configuration command
- B、The configuration is missing two authentication - related configuration commands
- C、Authentication type 9 is not supported; type 5 should be u sed insteaD
- D、The key numbers must begin with key 1, so change the key 3 command to key 1

第10题：
Router R1, an ASBR connected to the Internet and to backbone area 0, has been configured with a default - information originate command. Which of the following is true about the effects of this configuration command?（）
- A、R1 will always create and flood a default route into the OSPF domain.
- B、R1 will create and flood an LSA for prefix/length 0.0. 0.0/0 into the OSPF domain if R1's IP routing table has a route to 0.0.0.0/0.
- C、R1 will set a flag on the LSA for the subnet between itself and one of the ISPs, noting this subnet as a default network, regardless of whether R1 has a default route.
- D、R1 w ill set a flag on the LSA for the subnet between itself and one of the ISPs, noting this subnet as a default network, but only if R1 has a route to 0.0.0.0/0.
