Which action is taken by switch port enabled for PoE power classification override?

A. If a monitored port exceeds the maximum administrative value for power, the port is shutdown and err- disabled.
B. When a powered device begins drawing power from a PoE switch port, a syslog message is generated.
C. As power usage on a PoE switch port is checked, data flow to the connected device is temporarily paused.
D. If a switch determines that a device is using less than the minimum configured power, it assumes the device has failed and disconnects it.

Correct Answer: A

Explanation:

Explanation:
PoE monitoring and policing compares the power consumption on ports with the administrative maximum value (either a configured maximum value or the port’s default value). If the power consumption on a monitored port exceeds the administrative maximum value, the following actions occur:
– A syslog message is issued.
– The monitored port is shut down and error-disabled.
– The allocated power is freed.

What are two reasons that cause late collisions to increment on an Ethernet interface? (Choose two.)

A. when Carrier Sense Multiple Access/Collision Detection is used
B. when one side of the connection is configured for half-duplex
C. when the sending device waits 15 seconds before sending the frame again
D. when a collision occurs after the 32nd byte of a frame has been transmitted
E. when the cable length limits are exceeded

Correct Answer: BE

Explanation:

Explanation:
A late collision is defined as any collision that occurs after the first 512 bits (or 64th byte) of the frame have been transmitted. The usual possible causes are full-duplex/half-duplex mismatch, exceeded Ethernet cable length limits, or defective hardware such as incorrect cabling, non-compliant number of hubs in the network, or a bad NIC.
Late collisions should never occur in a properly designed Ethernet network. They usually occur when Ethernet cables are too long or when there are too many repeaters in the network.

Which IPv6 address block sends packets to a group address rather than a single address?

A. 2000::/3
B. FC00::/7
C. FE80::/10
D. FF00::/8

Correct Answer: D

Explanation:

Explanation:
FF00::/8 is used for IPv6 multicast and this is the IPv6 type of address the question wants to ask.
FE80::/10 range is used for link-local addresses. Link-local addresses only used for communications within the local subnetwork (automatic address configuration, neighbor discovery, router discovery, and by many routing protocols). It is only valid on the current subnet. It is usually created dynamically using a link-local prefix of FE80::/10 and a 64-bit interface identifier (based on 48-bit MAC address).

Which IPv6 address type provides communication between subnets and cannot route on the Internet?

A. link-local
B. unique local
C. multicast
D. global unicast

Correct Answer: B

Explanation:

Explanation:
A IPv6 Unique Local Address is an IPv6 address in the block FC00::/7. It is the approximate IPv6 counterpart of the IPv4 private address. It is not routable on the global Internet.
Note: In the past, Site-local addresses (FEC0::/10) are equivalent to private IP addresses in IPv4 but now they are deprecated.
Link-local addresses only used for communications within the local subnet. It is usually created dynamically using a link-local prefix of FE80::/10 and a 64-bit interface identifier (based on 48-bit MAC address).

Refer to the exhibit. Which statement explains the configuration error message that is received?

A. It belongs to a private IP address range.
B. The router does not support /28 mask.
C. It is a network IP address.
D. It is a broadcast IP address.

Correct Answer: D

Cisco Certified Network Associate (200-301 CCNA) – Question015

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

A. 172.9.0.0/16
B. 172.28.0.0/16
C. 192.0.0.0/8
D. 209.165.201.0/24

Correct Answer: B

Explanation:

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).

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

A. interface e0/0 description to XX-AXXX:XXXXX ip address 10.2.1.3 255.255.255.252
B. interface e0/0 description to XX-AXXX:XXXXX ip address 192.168.1.1 255.255.255.248
C. interface e0/0 description to XX-AXXX:XXXXX ip address 172.16.1.4 255.255.255.248
D. interface e0/0 description to XX-AXXX:XXXXX ip address 209.165.201.2 225.255.255.252

Correct Answer: D

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

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

Correct Answer: C

Explanation:

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.

DRAG DROP

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

Correct Answer: [img 0012-0002.jpg]

Explanation:

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
