質問 # 173
Refer to the exhibit.

The OSPF routing protocol is redistributed into the BGP routing protocol, but not all the OSPF routes are distributed into BGP Which action resolves the issue?

A. Use a route-map command to redistribute OSPF external routes defined in a prefix list.
B. Use a route-map command to redistribute OSPF external routes defined in an access list
C. Include the word external in the redistribute command
D. Include the word internal external in the redistribute command

正解：D

解説：
Explanation
If you configure the redistribution of OSPF into BGP without keywords, only OSPF intra-area and inter-area routes are redistributed into BGP, by default. You can use the internal keyword along with the redistribute command under router bgp to redistribute OSPF intra- and inter-area routes.
Use the external keyword along with the redistribute command under router bgp to redistribute OSPF external routes into BGP.
-> In order to redistribute all OSPF routes into BGP, we must use both internal and external keywords. The full command would be (suppose we are using OSPF 1):
redistribute ospf 1 match internal external
Note: The configuration shows match internal external 1 external 2. This is normal because OSPF automatically appends "external 1 external 2" in the configuration. In other words, keyword external = external 1 external 2. External 1 = O E1 and External 2 = O E2.

質問 # 174
An engineer configured a Cisco router to send reliable and encrypted notifications for any events to the management server. It was noticed that the notification messages are reliable but not encrypted. Which action resolves the issue?

A. Configure all devices for SNMPv3 informs with auth.
B. Configure all devices for SNMPv3 informs with priv.
C. Configure all devices for SNMPv3 traps with priv.
D. Configure all devices for SNMPv3 traps with auth.

正解：B

解説：
Explanation
SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send acknowledgments when this device receives traps."Send reliable and encrypted notifications for any events" so it is SNMP notifications. For encryption we need to configure "priv".

質問 # 175
Refer to the exhibit.

An engineer receives this error message when trying to access another router in-band from the serial interface connected to the console of R1. Which configuration is needed on R1 to resolve this issue?

A. Option A
B. Option B
C. Option D
D. Option C

正解：C

解説：
https://community.cisco.com/t5/other-network-architecture/out-of-band-router-access/td-p/333295 The "transport output none" command prevents any protocol connection made from R1.
Therefore our SSH connection to 192.168.12.2 was refused. In order to fix this problem we can configure "transport output ssh" under "line console 0" of R1.
Note: The parameter "-l" specifies the username to log in as on the remote machine.

質問 # 176
When determining if a system is capable of support, what is the minimum time spacing required for a BFD control packet to receive once a control packet is arrived?

A. Required Min RX Interval
B. Detect Mult
C. Required Min Echo RX Interval
D. Desired Min TX Interval

正解：A

解説：
Explanation
Desired Min TX Interval: This is the minimum interval, in microseconds, that the local system would like to use when transmitting BFD Control packets, less any jitterapplied. The value zero is reserved.
Required Min Echo RX Interval: This is the minimum interval, in microseconds, between received BFD Echo packets that this system is capable of supporting, less anyjitter applied by the sender. If this value is zero, the transmitting system does not support the receipt of BFD Echo packets.

質問 # 177
Refer to the exhibit.

質問 # 179
Which function does LDP provide in an MPLS topology?

A. It provides hop-by-hop forwarding in an MPLS topology for LSRs.
B. It enables a MPLS topology to connect multiple VPNs to P routers.
C. It exchanges routes for MPLS VPNs across different VRFs.
D. It provides a means for LSRs to exchange IP routes.

正解：A

質問 # 180
Refer to the exhibit.

An engineer is trying to redistribute OSPF to BGP, but not all of the routes are redistributed. What is the reason for this issue?

A. By default, only internal routes and external type 1 routes are redistributed into BGP
B. By default, only internal OSPF routes are redistributed into BGP
C. Only classful networks are redistributed from OSPF to BGP
D. BGP convergence is slow, so the route will eventually be present in the BGP table

正解：B

解説：
Explanation
If you configure the redistribution of OSPF into BGP without keywords, only OSPF intra-area and inter-area routes are redistributed into BGP, by default.
You can redistribute both internal and external (type-1 & type-2) OSPF routes via this command:
Router(config-router)#redistribute ospf 1 match internal external 1 external 2
