Final - P2

What are two common causes of signal degradation when using UTP cabling? (Choose two.)

• improper termination
• low-quality cable or connectors
• low-quality shielding in cable
• installing cables in conduit
• loss of light over long distances

Which subnet would include the address 192.168.1.96 as a usable host address?

• 192.168.1.64/26
• 192.168.1.64/29
• 192.168.1.32/27
• 192.168.1.32/28

Refer to the exhibit. On the basis of the output, which two statements about network connectivity are correct? (Choose two.)

• There are 4 hops between this device and the device at 192.168.100.1
• There is connectivity between this device and the device at 192.168.100.1.
• This host does not have a default gateway configured.
• The connectivity between these two hosts allows for videoconferencing calls.
• The average transmission time between the two hosts is 2 milliseconds.

Which two statements describe how to assess traffic flow patterns and network traffic types using a protocol analyzer? (Choose two.)

• Capture traffic during peak utilization times to get a good representation of the different traffic types.
• Perform the capture on different network segments.
• Capture traffic on the weekends when most employees are off work.
• Only capture traffic in the areas of the network that receive most of the traffic such as the data center.
• Only capture WAN traffic because traffic to the web is responsible for the largest amount of traffic on a network.

Which three layers of the OSI model map to the application layer of the TCP/IP model? (Choose three.)

• application
• session
• presentation
• network
• datalink

What is the consequence of configuring a router with the ipv6 unicast-routing global configuration command?​

• The IPv6 enabled router interfaces begin sending ICMPv6 Router Advertisement messages.
• All router interfaces will be automatically activated.
• Each router interface will generate an IPv6 link-local address.​
• It statically creates a global unicast address on this router.​

Refer to the exhibit. If PC1 is sending a packet to PC2 and routing has been configured between the two routers, what will R1 do with the Ethernet frame header attached by PC1?

• remove the Ethernet header and configure a new Layer 2 header before sending it out S0/0/0

• nothing, because the router has a route to the destination network

• open the header and use it to determine whether the data is to be sent out S0/0/0

• open the header and replace the destination MAC address with a new one

What will happen if the default gateway address is incorrectly configured on a host?

• The host cannot communicate with hosts in other networks.
• The host cannot communicate with other hosts in the local network.
• 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 switch will not forward packets initiated by the host.

A network administrator is adding a new LAN to a branch office. The new LAN must support 90 connected devices. What is the smallest network mask that the network administrator can use for the new network?

• 255.255.255.128
• 255.255.255.240
• 255.255.255.248
• 255.255.255.224

What are two features of ARP? (Choose two.)

• If a host is ready to send a packet to a local destination device and it has the IP address but not the MAC address of the destination, it generates an ARP broadcast.
• If a device receiving an ARP request has the destination IPv4 address, it responds with an ARP reply.
• When a host is encapsulating a packet into a frame, it refers to the MAC address table to determine the mapping of IP addresses to MAC addresses.
• An ARP request is sent to all devices on the Ethernet LAN and contains the IP address of the destination host and its multicast MAC address.
• If no device responds to the ARP request, then the originating node will broadcast the data packet to all devices on the network segment.
