質問 # 556
R1 has learned route 192.168.12.0/24 via IS-IS. OSPF, RIP. and Internal EIGRP Under normal operating conditions, which routing protocol is installed in the routing table?
- A. RIP
- B. IS-IS
- C. Internal EIGRP
- D. OSPF
正解：C
解説：
With the same route (prefix), the router will choose the routing protocol with lowest Administrative Distance (AD) to install into the routing table. The AD of Internal EIGRP (90) is lowest so it would be chosen. The table below lists the ADs of popular routing protocols.
Note: The AD of IS-IS is 115. The "EIGRP" in the table above is "Internal EIGRP". The AD of "External EIGRP" is 170. An EIGRP external route is a route that was redistributed into EIGRP.
質問 # 557
What is a DHCP client?
- A. a server that dynamically assigns IP addresses to hosts.

- C. a workstation that requests a domain name associated with its IP address
- D. a host that is configured to request an IP address automatically
正解：D
質問 # 558
Refer to the exhibit.
Router R4 is dynamically learning the path to the server. If R4 is connected to R1 via OSPF Area 20, to R2 v2ia R2 BGP, and to R3 via EIGRP 777, which path is installed in the routing table of R4?
- A. the path through R1, because the OSPF administrative distance is 110
- B. the path through R3. because the EIGRP administrative distance is lower than OSPF and BGP
- C. the path through R2. because the IBGP administrative distance is 200
- D. the path through R2 because the EBGP administrative distance is 20
正解：D
質問 # 559

質問 # 566
Refer to the Exhibit.
Connectivity between three routers has been established, and IP services must be configured jn the order presented to complete the implementation Tasks assigned include configuration of NAT, NTP, DHCP, and SSH services.
1. All traffic sent from R3 to the R1 Loopback address must be configured for NAT on R2. All source addresses must be translated from R3 to the IP address of Ethernet0/0 on R2, while using only a standard access list named NAT To verify, a ping must be successful to the R1 Loopback address sourced from R3. Do not use NVI NAT configuration.
2. Configure R1 as an NTP server and R2 as a client, not as a peer, using the IP address of the R1 Ethernet0/2 interface. Set the clock on the NTP server for midnight on January 1, 2019.
3. Configure R1 as a DHCP server for the network 10.1.3.0/24 in a pool named TEST. Using a single command, exclude addresses 1-10 from the range. Interface Ethernet0/2 on R3 must be issued the IP address of 10.1.3.11 via DHCP.
4. Configure SSH connectivity from R1 to R3, while excluding access via other remote connection protocols. Access for user root and password Cisco must be set on router R3 using RSA and 1024 bits. Verify connectivity using an SSH session from router R1 using a destination address of 10.1.3.11. Do NOT modify console access or line numbers to accomplish this task.
- A. See the Explanation below
正解：A

質問 # 567
When OSPF learns multiple paths to a network, how does it select a route?
- A. For each existing interface, it adds the metric from the source router to the destination to calculate the route with the lowest bandwidth.
- B. It divides a reference bandwidth of 100 Mbps by the actual bandwidth of the exiting interface to calculate the route with the lowest cost.
- C. It counts the number of hops between the source router and the destination to determine the route with the lowest metric.
- D. It multiples the active K values by 256 to calculate the route with the lowest metric.
正解：B
