質問 # 13
Your network has an unmanaged switch between the hosts and your EX Series switch. After the traffic enters the EX Series switch, each host must be on a separate VLAN.
How would you accomplish this task?

A. Configure interface ge-0/0/3 to a mode trunk to assign the VLANs.
B. Configure an input firewall filter on interface ge-0/0/3 to match the source MAC or IP address of the hosts to assign the VLANs.
C. Configure VSTP on interface ge-0/0/1 to assign the VLANs.
D. Configure an output firewall filter on interface ge-0/0/1 to match the destination MAC or IP address of the hosts to assign the VLANs.

正解：A

質問 # 14

A. Default VSTP bridge priority values are configured.
B. DS-1 is the root bridge for VLAN 10.
C. BPDUs from the root bridge for VLAN 20 have been received on the ge-0/0/7.0 interface.
D. BPDUs from the root bridge for VLAN 10 have been received on the ge-0/0/7.0 interface.

質問 # 16
Which two statements about OSPF routing policies are correct? (Choose two.)

A. By default, OSPF import policies reject network-summary LSAs.
B. By default, OSPF export policies reject network-summary LSAs.
C. By default, OSPF export policies accept network-summary LSAs.

正解：B、D

質問 # 17
You must ensure that all routes in the 10.0.0/8 address range are not advertised outside of your AS. Which well-known BGP community should be assigned to these addresses to accomplish this task?

A. no-peer
B. no-export
C. internet
D. no-advertise

正解：B

解説：
For specifying the BGP community attribute only, you also can specify community-ids as one of the following well-known community names defined in RFC 1997:
no-advertise - Routes containing this community name are not advertised to other BGP peers.
no-export - Routes containing this community name are not advertised outside a BGP confederation boundary.
no-export-subconfed - Routes containing this community are advertised to IBGP peers with the same AS number, but not to members of other confederations.
llgr-stale - Adds a community to a long-lived stale route when it is readvertised.
no-llgr - Marks routes which a BGP speaker does not want to be retained by LLGR. The Notification message feature does not have any associated configuration parameters.
