  1. RIB

  2. IPv6

  3. Ping

  4. Disable Logging

Answer: D

Question No: 212 – (Topic 7)

Scenario:

You are a junior network engineer for a financial company, and the main office network is experiencing network issues. Troubleshoot the network issues.

Router R1 connects the main office to the internet, and routers R2 and R3 are internal routers.

NAT is enabled on router R1.

The routing protocol that is enabled between routers R1, R2 and R3 is RIPv2.

R1 sends the default route into RIPv2 for the internal routers to forward internet traffic to R1.

You have console access on R1, R2 and R3 devices. Use only show commands to troubleshoot the issues.

Why applications that are installed on PC#39;s in R2 LAN network 10.100.20.0/24 are unable to communicate with server1?

  1. A standard ACL statement that is configured on R1 is blocking the traffic sourced from Server1 network.

  2. A standard ACL statement that is configured on R2 is blocking the traffic sourced from Setver1 network.

  3. A standard ACL statement that is configured on R2 is blocking the traffic sourced from R2 LAN network.

  4. A standard ACL statement that is configured on R1 is blocking the traffic sourced from R2 LAM network

What is the cause of the problem?

  1. The cabling connecting host A to Switch3 is too long.

  2. The address of host B is a broadcast address.

  3. The IP address of interface Fa0/0 of Router1 is not a usable address.

  4. The cable connecting Switch2 and Switch3 should be a crossover.

  5. The IP address of Server 1 is in the wrong subnet.

Answer: D

Answer: B,F

Question No: 217 – (Topic 7)

Which RFC was created to alleviate the depletion of IPv4 public addresses?

  1. RFC 4193

  2. RFC 1519

  3. RFC 1518

  4. RFC 1918

Answer: C

Explanation: Explanation

The RFC 1518 is Classless Interdomain Routing (CIDR). CIDR is a mechanism developed to help alleviate the problem of exhaustion of IP addresses and growth of routing tables.

The problems were:

With the classful routing system, individual networks were either limited to 254 hosts (/24) or 65,534 hosts (/16). For many network enterprises, 254 hosts were not enough and 65,534 were too large to be used efficiently.

Routing information overload. The size and rate of growth of the routing tables in Internet routers is beyond the ability of current software (and people) to effectively manage.

Eventual exhaustion of IP network numbers.

To solve these problem, CIDR was selected as the solution in 1992.

In contrast to classful routing, which categorizes addresses into one of three blocks, CIDR allows for blocks of IP addresses to be allocated to Internet service providers. The blocks are then split up and assigned to the provider’s customers.

According to the CIDR standard, the first part of an IP address is a prefix, which identifies the network. The prefix is followed by the host identifier so that information packets can be sent to particular computers within the network. A CIDR address includes the standard 32- bit IP address and also the network prefix. For example, a CIDR address of 200.1.45.2/26, the 鈥?26鈥?indicates the first 26 bits are used to identify the unique network, leaving the remaining bits to identify the specific hosts.

Therefore, instead of assigning the whole block of a class B or C address, now smaller blocks of a class can be assigned. For example, instead of assigning a whole block of 200.1.45.0/24, a smaller block, like 200.1.45.0/27 or 200.1.45.32/27, can be assigned. In fact, CIDR is specified in RFCs 1518,1519 and 1520 so answer 鈥淩FC 1519鈥?is also acceptable.

Question No: 218 – (Topic 7)

Which statement about unicast frame forwarding on a switch is true?

  1. The TCAM table stores destination MAC addresses

  2. If the destination MAC address is unknown, the frame is flooded to every port that is configured in the same VLAN except on the port that it was received on.

  3. The CAM table is used to determine whether traffic is permitted or denied on a switch

  4. The source address is used to determine the switch port to which a frame is forwarded

Answer: B
