When configuring IPv6 on an interface, which two IPv6 multicast groups are joined? (Choose two.)

  1. 2000::/3
  2. 2002::5
  3. FC00::/7
  4. FF02::1
  5. FF02::2

Answer(s): D,E

Explanation:

When an interface is configured with IPv6 address, it automatically joins the all nodes (FF02::1) and solicited-node (FF02::1:FFxx:xxxx) multicast groups. The all- node group is used to communicate with all interfaces on the local link, and the solicited-nodes multicast group is required for link-layer address resolution.
Routers also join a third multicast group, the all-routers group (FF02::2).

DRAG DROP (Drag and Drop is not supported)
Refer to the exhibit.


Drag and drop the networking parameters from the left onto the correct values on the right.
Select and Place:

  1. See Explanation section for answer.

Answer(s): A

Explanation:



The “ip route” and “ip addr show eth1” are Linux commands.
“ip route”: display the routing table
“ip addr show eth1”: get depth information (only on eth1 interface) about your network interfaces like IP Address, MAC Address information



What is the default behavior of a Layer 2 switch when a frame with an unknown destination MAC address is received?

  1. The Layer 2 switch forwards the packet and adds the destination MAC address to its MAC address table.
  2. The Layer 2 switch sends a copy of a packet to CPU for destination MAC address learning.
  3. The Layer 2 switch floods packets to all ports except the receiving port in the given VLAN.
  4. The Layer 2 switch drops the received frame.

Answer(s): C

Explanation:

If the destination MAC address is not in the CAM table (unknown destination MAC address), the switch sends the frame out all other ports that are in the same VLAN as the received frame. This is called flooding. It does not flood the frame out the same port on which the frame was received.



An engineer must configure a /30 subnet between two routes. Which usable IP address and subnet mask combination meets this criteria?

  1. interface e0/0 description to XX-AXXX:XXXXX ip address 10.2.1.3 255.255.255.252
  2. interface e0/0 description to XX-AXXX:XXXXX ip address 192.168.1.1 255.255.255.248
  3. interface e0/0 description to XX-AXXX:XXXXX ip address 172.16.1.4 255.255.255.248
  4. interface e0/0 description to XX-AXXX:XXXXX ip address 209.165.201.2 225.255.255.252

Answer(s): D



Which network allows devices to communicate without the need to access the Internet?

  1. 172.9.0.0/16
  2. 172.28.0.0/16
  3. 192.0.0.0/8
  4. 209.165.201.0/24

Answer(s): B

Explanation:

This question asks about the private ranges of IPv4 addresses. The private ranges of each class of IPv4 are listed below:
-Class A private IP address ranges from 10.0.0.0 to 10.255.255.255
-Class B private IP address ranges from 172.16.0.0 to 172.31.255.255
-Class C private IP address ranges from 192.168.0.0 to 192.168.255.255
-Only the network 172.28.0.0/16 belongs to the private IP address (of class B).
