200-301 practice questions 731–740

1. Question 731 · 1334 in bank

   

   Refer to the exhibit. An engineer assumes a configuration task from a peer. Router A must establish an OSPF neighbor relationship with neighbor 172.1.1.1. The output displays the status of the adjacency after 2 hours. What is the next step in the configuration process for the routers to establish an adjacency?

   • AConfigure router A to use the same MTU size as router B.
   • BConfigure a point-to-point link between router A and router B.
   • CSet the router B OSPF ID to the same value as its IP address.
   • DSet the router B OSPF ID to a nonhost address.

   Show answer

   Answer: A

   Explanation

   In Exstart/Exchange State, when attempting to run OSPF between a Cisco router and another vendor's router. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighboring router ignores the packet.

   Select 2

   

   Refer to the exhibit. Which two configurations must the engineer apply on this network so that R1 becomes the DR? (Choose two.)

   • AR3(config)#interface fastethernet 0/0 R3(config-if)#ip ospf priority 0
   • BR1(config)#router ospf 1 R1(config-router)#router-id 192.168.100.1
   • CR1(config)#interface fastethernet 0/0 R1(config-if)#ip ospf priority 200
   • DR1(config)#interface fastethernet 0/0 R1(config-if)#ip ospf priority 0
   • ER3(config)#interface fastethernet 0/0 R3(config-if)#ip ospf priority 200

   Show answer

   Answer: AC

   Explanation

   Answer A is settings router 3 to have priority 0(0 means they are not allowed to participate in DR/BDR election) Answer C is making R1 to have a higher priority(default is 1 but putting very high number is only for safety reasons to ensure that the R1 is elected DR)

3. Question 733 · 1334 in bank

   

   Refer to the exhibit. Which command configures OSPF on the point-to-point link between routers R1 and R2?

   • Arouter-id 10.0.0.15
   • Bneighbor 10.1.2.0 cost 180
   • Cnetwork 10.0.0.0 0.0.0.255 area 0
   • Dip ospf priority 100

   Show answer

   Answer: C

   Explanation

   Yes, option 'c' is correct. There appears to be some conjecture about the mismatch in wildcard mask - let me clear it up. Note that the wildcard mask in the answer doesn’t match that in the graphic. This is OK – don’t panic. The network command is used to define the range of addresses owned by the router that will participate in the OSPF routing process. Above, if an interface is between 10.0.0.1 and 10.0.0.254, it participates in OSPF, area 0. It just so happens that interface Serial 0/1 is the only interface owned by the router that qualifies for this inclusion.

4. Question 734 · 1334 in bank

   

   Refer to the exhibit. A network engineer is in the process of establishing IP connectivity between two sites. Routers R1 and R2 are partially configured with IP addressing. Both routers have the ability to access devices on their respective LANs. Which command set configures the IP connectivity between devices located on both LANs in each site?

   • AR1 ip route 192.168.1.1 255.255.255.0 GigabitEthernet0/1 R2 ip route 10.1.1.1 255.255.255.0 GigabitEthernet0/1
   • BR1 ip route 192.168.1.0 255.255.255.0 GigabitEthernet0/0 R2 ip route 10.1.1.1 255.255.255.0 GigabitEthernet0/0
   • CR1 ip route 0.0.0.0 0.0.0.0 209.165.200.225 R2 ip route 0.0.0.0 0.0.0.0 209.165.200.226
   • DR1 ip route 0.0.0.0 0.0.0.0 209.165.200.226 R2 ip route 0.0.0.0 0.0.0.0 209.165.200.225

   Show answer

   Answer: D

   Explanation

   Answer D is correct as it is stating any route goes through next hop of 2019.165.200.226(for R1) while any route next hops to 209.165.200.225(On R2) Answer A and B are not correct as the question states that both routers can access their respective LANs thus having a static route in each own LAN makes no sense.

   What is the destination MAC address of a broadcast frame?

   • A00:00:0c:07:ac:01
   • Bff:ff:ff:ff:ff:ff
   • C43:2e:08:00:00:0c

   Show answer

   Answer: B

   Explanation

   Ref: Broadcast Frame - an overview | ScienceDirect Topics “… Cisco IOS Switch Basics Switch Concepts … • Broadcasts… Layer 2 broadcast frames have a destination Media Access Control (MAC) address of FF:FF:FF:FF:FF:FF and Layer 3 broadcast addresses have a destination Internet Protocol (IP) address that is set for the broadcast of that particular network (the address varies, so don't always assume that an IP address ending with 255 is the broadcast address). …” A. 00:00:0c:07:ac:01 Wrong answer. B. ff:ff:ff:ff:ff:ff Correct answer. C. 43:2e:08:00:00:0c Wrong answer. D. 00:00:0c:43:2e:08 Wrong answer. E. 00:00:0c:ff:ff:ff Wrong answer.

7. Question 737 · 1334 in bank

   

   Refer to the exhibit. Packets received by the router from BGP enter via a serial interface at 209.165.201.1. Each route is present within the routing table. Which interface is used to forward traffic with a destination IP of 10.1.1.19?

   • AF0/0
   • BF0/1
   • CF0/4
   • DF0/3

   Show answer

   Answer: A

   Explanation

   To qualify, the option must match two requirements: 1. It must be in range of the advertised route. 2. If there are multiple legitimate routes, it is the route with the longest match. Is test 1 satisfied?... 10.1.1.16/28 has (32-28 = 4-bits for host addresses). 2^4 = 16 hosts (well, excluding N/W and B/C addresses we get 14 usable hosts). Range is 10.1.1.16 -> 10.1.1.31, and 10.1.1.19 falls within this range. Is test 2 satisfied? This route is a /28, which is longer than any other. If there were multiple /28 routes, then choose the one with the lowest AD value (in this case, EIGRP then OPSF, then RIP).

8. Question 738 · 1334 in bank

   

   Refer to the exhibit. Which route must be configured on R1 so that OSPF routing is used when OSPF is up, but the server is still reachable when OSPF goes down?

   • Aip route 10.1.1.10 255.255.255.255 gi0/0 125
   • Bip route 10.1.1.0 255.255.255.0 172.16.2.2 100
   • Cip route 10.1.1.0 255.255.255.0 gi0/1 125
   • Dip route 10.1.1.10 255.255.255.255 172.16.2.2 100

   Show answer

   Answer: A

   Explanation

   Answer is A. At a glance, B has a lower manually set AD of 100. C command is wrong anyway, if you want to use the interface name instead of the next hop, you use the local router's interface which is R1's g0/0. G0/1 is the next hop to R2. D has a lower AD than 110. A has the correct command with a static host route directly to the server, a /32 subnet (host route), the local router's exit interface of g0/0, and a higher manually set AD of 125.

10. Question 740 · 1334 in bank

    

    Refer to the exhibit. Which prefix did router R1 learn from internal EIGRP?

    • A192.168.3.0/24
    • B192.168.1.0/24
    • C172.16.1.0/24
    • D192.168.2.0/24

    Show answer

    Answer: D

    Explanation

    you can also get the answer as the AD for internal EIGRP is 90. and External in 170 so in the question they have asked the internal EIGRP which is only with ip address in D. the AD for OSPF is110 so options A and B is out of question anyway!
