  • MAC addresses are used during the IP packet encapsulation.
  • IP relies on upper layer services to handle situations of missing or out-of-order packets.

Explanation: IP protocol is a connection-less protocol, considered unreliable in terms of end-to-end delivery. It does not provide error control in the cases where receiving packets are out-of-order or in cases of missing packets. It relies on upper layer services, such as TCP, to resolve these issues.

Q
  1. Why is NAT not needed in IPv6?​
  • Because IPv6 has integrated security, there is no need to hide the IPv6 addresses of internal networks.​
  • Any host or user can get a public IPv6 network address because the number of available IPv6 addresses is extremely large.​
  • The problems that are induced by NAT applications are solved because the IPv6 header improves packet handling by intermediate routers.​
  • The end-to-end connectivity problems that are caused by NAT are solved because the number of routes increases with the number of nodes that are connected to the Internet.

  • The end-to-end connectivity problems that are caused by NAT are solved because the number of routes increases with the number of nodes that are connected to the Internet.

Explanation: The large number of public IPv6 addresses eliminates the need for NAT. Sites from the largest enterprises to single households can get public IPv6 network addresses. This avoids some of the NAT-induced application problems that are experienced by applications that require end-to-end connectivity.

Q
  1. Within a production network, what is the purpose of configuring a switch with a default gateway address?
  • Hosts that are connected to the switch can use the switch default gateway address to forward packets to a remote destination.
  • A switch must have a default gateway to be accessible by Telnet and SSH.
  • The default gateway address is used to forward packets originating from the switch to remote networks.
  • It provides a next-hop address for all traffic that flows through the switch.

  • The default gateway address is used to forward packets originating from the switch to remote networks.
  • It provides a next-hop address for all traffic that flows through the switch.

Explanation: A default gateway address allows a switch to forward packets that originate on the switch to remote networks. A default gateway address on a switch does not provide Layer 3 routing for PCs that are connected on that switch. A switch can still be accessible from Telnet as long as the source of the Telnet connection is on the local network.

A
  1. What is a basic characteristic of the IP protocol?
  • connectionless
  • media dependent
  • user data segmentation
  • reliable end-to-end delivery

Explanation: Internet Protocol (IP) is a network layer protocol that does not require initial exchange of control information to establish an end-to-end connection before packets are forwarded. Thus, IP is connectionless and does not provide reliable end-to-end delivery by itself. IP is media independent. User data segmentation is a service provided at the transport layer.

Q
  1. Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?
  • Time-to-Live
  • Sequence Number
  • Acknowledgment Number
  • Differentiated Services
A
  1. Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?
  • Time-to-Live
  • Sequence Number
  • Acknowledgment Number
  • Differentiated Services

Explanation: The value of the Time-to-Live (TTL) field in the IPv4 header is used to limit the lifetime of a packet. The sending host sets the initial TTL value; which is decreased by one each time the packet is processed by a router. If the TTL field decrements to zero, the router discards the packet and sends an Internet Control Message Protocol (ICMP) Time Exceeded message to the source IP address. The Differentiated Services (DS) field is used to determine the priority of each packet. Sequence Number and Acknowledgment Number are two fields in the TCP header.

Q
  1. What routing table entry has a next hop address associated with a destination network?
  • directly-connected routes
  • local routes
  • remote routes
  • C and L source routes
A
  1. What routing table entry has a next hop address associated with a destination network?
  • directly-connected routes
  • local routes
  • remote routes
  • C and L source routes

Explanation: Routing table entries for remote routes will have a next hop IP address. The next hop IP address is the address of the router interface of the next device to be used to reach the destination network. Directly-connected and local routes have no next hop, because they do not require going through another router to be reached.

Q
  1. How do hosts ensure that their packets are directed to the correct network destination?
  • They have to keep their own local routing table that contains a route to the loopback interface, a local network route, and a remote default route.​
  • They always direct their packets to the default gateway, which will be responsible for the packet delivery.
  • They search in their own local routing table for a route to the network destination address and pass this information to the default gateway.
  • They send a query packet to the default gateway asking for the best route.

  • They search in their own local routing table for a route to the network destination address and pass this information to the default gateway.
  • They send a query packet to the default gateway asking for the best route.

Explanation: Hosts must maintain their own local routing table to ensure that network layer packets are directed to the correct destination network. This local table typically contains a route to the loopback interface, a route to the network that the host is connected to, and a local default route, which represents the route that packets must take to reach all remote network addresses.

Q
  1. Which destination address is used in an ARP request frame?

  • FFFF.FFFF.FFFF
  • AAAA.AAAA.AAAA
  • the physical address of the destination host

  1. Which destination address is used in an ARP request frame?
  • 0.0.0.0
  • 255.255.255.255
  • FFFF.FFFF.FFFF
  • AAAA.AAAA.AAAA
  • the physical address of the destination host

Explanation: The purpose of an ARP request is to find the MAC address of the destination host on an Ethernet LAN. The ARP process sends a Layer 2 broadcast to all devices on the Ethernet LAN. The frame contains the IP address of the destination and the broadcast MAC address, FFFF.FFFF.FFFF. The host with the IP address that matches the IP address in the ARP request will reply with a unicast frame that includes the MAC address of the host. Thus the original sending host will obtain the destination IP and MAC address pair to continue the encapsulation process for data transmission.

  • interface fastethernet 0/0
  • line vty 0 4
  • line console 0
  • enable secret cisco
  • login
  • password cisco

Explanation: The three commands needed to password protect the console port are as follows:

  • line console 0
  • password cisco
  • login
    The interface fastethernet 0/0 command is commonly used to access the configuration mode used to apply specific parameters such as the IP address to the Fa0/0 port. The line vty 0 4 command is used to access the configuration mode for Telnet. The0and 4 parameters specify ports 0 through 4, or a maximum of five simultaneous Telnet connections. The enable secret command is used to apply a password used on the router to access the privileged mode.

A
  1. Which two functions are primary functions of a router? (Choose two.)
  • packet forwarding
  • microsegmentation
  • domain name resolution
  • path selection
  • flow control

Explanation: A router accepts a packet and accesses its routing table to determine the appropriate exit interface based on the destination address. The router then forwards the packet out of that interface.

  • The contents of ROM will change.
  • The contents of RAM will change.
  • The contents of NVRAM will change.
  • The contents of flash will change.

Explanation: The command copy running-config startup-config copies the running-configuration file from RAM into NVRAM and saves it as the startup-configuration file. Since NVRAM is none-volatile memory it will be able to retain the configuration details when the router is powered off.

Q
  1. What will happen if the default gateway address is incorrectly configured on a host?
  • The host cannot communicate with other hosts in the local network.
  • The switch will not forward packets initiated by the host.
  • The host will have to use ARP to determine the correct address of the default gateway.
  • The host cannot communicate with hosts in other networks.
  • A ping from the host to 127.0.0.1 would not be successful.

  • The host will have to use ARP to determine the correct address of the default gateway.
  • The host cannot communicate with hosts in other networks.
  • A ping from the host to 127.0.0.1 would not be successful.

Explanation: When a host needs to send a message to another host located on the same network, it can forward the message directly. However, when a host needs to send a message to a remote network, it must use the router, also known as the default gateway. This is because the data link frame address of the remote destination host cannot be used directly. Instead, the IP packet has to be sent to the router (default gateway) and the router will forward the packet toward its destination. Therefore, if the default gateway is incorrectly configured, the host can communicate with other hosts on the same network, but not with hosts on remote networks.

Q
  1. What are two potential network problems that can result from ARP operation? (Choose two.)
  • Manually configuring static ARP associations could facilitate ARP poisoning or MAC address spoofing.
  • On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays.
  • Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent of intercepting network traffic.
  • Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.
  • Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port.

  • Large numbers of ARP request broadcasts could cause the host MAC address table to overflow and prevent the host from communicating on the network.
  • Multiple ARP replies result in the switch MAC address table containing entries that match the MAC addresses of hosts that are connected to the relevant switch port.

Explanation: Large numbers of ARP broadcast messages could cause momentary data communications delays. Network attackers could manipulate MAC address and IP address mappings in ARP messages with the intent to intercept network traffic. ARP requests and replies cause entries to be made into the ARP table, not the MAC address table. ARP table overflows are very unlikely. Manually configuring static ARP associations is a way to prevent, not facilitate, ARP poisoning and MAC address spoofing. Multiple ARP replies resulting in the switch MAC address table containing entries that match the MAC addresses of connected nodes and are associated with the relevant switch port are required for normal switch frame forwarding operations. It is not an ARP caused network problem.
