1. Question 751 · 1334 in bank

   

   Refer to the exhibit. Router R1 currently is configured to use R3 as the primary route to the internet, and the route uses the default administrative distance settings. A network engineer must configure R1 so that it uses R2 as a backup, but only if R3 goes down. Which command must the engineer configure on R1 so that it correctly uses R2 as a backup route, without changing the administrative distance configuration on the link to R3?

   • Aip route 0.0.0.0 0.0.0.0 209.165.201.5.10
   • Bip route 0.0.0.0 0.0.0.0 g0/1 1
   • Cip route 0.0.0.0 0.0.0.0 209.165.200.226 1
   • Dip route 0.0.0.0 0.0.0.0 g0/1 6

   Show answer

   Answer: D

   Explanation

   Important thing to take note of is, the syntax for creating a default static route or connected static route uses the exit interface or output interface of source device (that’s the interface on which all packets are sent to the destination network). Some of us may confuse and think to use Gi0/0 interface on R3 in the command, but the interface to configure the backup route here must use the exit interface on the R1 itself i.e. Gi0/1. So command will be: ip route 0.0.0.0 0.0.0.0 g0/1 6 ("6" here is AD that's greater than the connected route's AD i.e., 1)

2. Question 752 · 1334 in bank

   

   Refer to the exhibit. Which action must be taken to ensure that router A is elected as the DR for OSPF area 0?

   • AConfigure the router A interfaces with the highest OSPF priority value within the area
   • BConfigure router B and router C as OSPF neighbors of router A
   • CConfigure the OSPF priority on router A with the lowest value between the three routers.
   • DConfigure router A with a fixed OSPF router ID

   Show answer

   Answer: A

   Explanation

   - The Router with the highest OSPF interface priority on a segment becomes the DR. This is provided using the interface command: ip ospf priority The default OSPF priority is 1. - Router with the next highest OSPF interface priority becomes the BDR. - If router priorities are equal, the highest Router ID (RID) breaks the tie. - The OSPF Router ID for a router is found by: 1. The router-id config-router command. 2. If that doesn’t exist, then the highest IP address on a loopback is used. 3. If that doesn’t exist, then the highest IP address on an up physical is used.

   Refer to the exhibit. Packets received by the router from BGP enter via a serial interface at 209.165.201.10. Each route is present within the routing table. Which interface is used to forward traffic with a destination IP of 10.10 10 24?

   • AF0/10
   • BF0/11
   • CF0/12
   • DF0/1

   Show answer

   Answer: B

   Explanation

   Dear Danaah, When installing to routing table is AD and Metric Only When choosing a route from routing table is Longest Prefix, AD and Metric can play a role Since the question stats based on routing table means now we have to consider 3 factors(longest prefix, AD and Metric) however all are /24 so longest prefix is out of the question. Now comes the tricky part If there are 2 or more routes to the same destination using different protocol is AD If there are 2 or more routes to the same destination using same protocol is Metric In this case example, OSPF route via F0/13 and EIGRP route via F0/11 are viable options however they ask to choose 1 so in the answer sheet is EIGRP route via F0/11 available thus being the answer.

4. Question 754 · 1334 in bank

   

   Refer to the exhibit. If OSPF is running on this network, how does Router2 handle traffic from Site B to 10.10.13.128/25 at Site A?

   • AIt sends packets out of interface Fa0/1.
   • BIt sends packets out of interface Fa0/2.
   • CIt load-balances traffic out of Fa0/1 and Fa0/2.
   • DIt is unreachable and discards the traffic.

   Show answer

   Answer: D

   Explanation

   Duh!, I just realized that the questions is asking for subnet 10.10.13.128/25 and the routes in the table represent 10.10.13.0/25.

   Refer to the exhibit. Router R1 resides in OSPF Area 0. After updating the R1 configuration to influence the paths that it will use to direct traffic, an engineer verified that each of the four Gigabit interfaces has the same route to 10 10.0.0/16. Which interface will R1 choose to send traffic to reach the route?

   • AGigabitEthernet0/0
   • BGigabitEthernet0/1
   • CGigabitEthernet0/2
   • DGigabitEthernet0/3

   Answer: B

   Explanation

   ref BW 100000 MB ref BW BW G0/0 100000MB divided by 10000MB (or 10000000KB) = 10 cost G0/1 100000MB divided by 100000MB (or 100000000KB) = 1 cost

6. Question 756 · 1334 in bank

   

   Refer to the exhibit. Which network prefix was learned via EIGRP?

   • A172.160.0/16
   • B207.165.200.0/24
   • C192.168.1.0/24
   • D192.168.2.0/24

   Show answer

   Answer: D

   Explanation

   Connected = 0 Static Route = 1 EIGRP Summary Route = 5 eBGP (external) = 20 EIGRP (Internal) = 90 OSPF = 110 IS-IS = 115 RIP = 120 EIGRP (external) =170 iBGP (internal BGP) = 200 EIGRP Summary Route = 5

7. Question 757 · 1334 in bank

   

   Refer to the exhibit. Which command must be issued to enable a floating static default route on router A?

   • Aip route 0.0.0.0 0.0.0.0 192.168.1.2 10
   • Bip route 0.0.0.0 0.0.0.0 192.168.1.2
   • Cip default-gateway 192.168.2.1
   • Dip route 0.0.0.0 0.0.0.0 192.168.2.1 10

   Show answer

   Answer: A

   Explanation

   A & D are the only answers with a configured distance metric (10). A floating static route is meant to be a backup. The current route has a route traveling through Router B. So it would make sense we have our backup (floating static route) going through Router C with a metric higher than a default route (1).

    Refer to the exhibit. When an administrator executes the show ip route command on router D to view its routing table, which value is displayed for the administrative distance for the route to network 192.168 1.0?

    • A110
    • B120
    • C170
    • D90

    Show answer

    Answer: A
