  Correct Answer: C

• Question 1343:

  What must be considered before deploying virtual machines?

  A. resource limitations, such as the number of CPU cores and the amount of memory

  B. support for physical peripherals, such as monitors, keyboards, and mice

  C. whether to leverage VSM to map multiple virtual processors to two or more virtual machines

  D. location of the virtual machines within the data center environment

  Correct Answer: A

• Question 1344:

  What are two facts that differentiate optical-fiber cabling from copper cabling? (Choose two.)

  A. It is less expensive when purchasing patch cables.

  B. It carries electrical current further distances for PoE devices.

  C. It provides greater throughput options.

  D. It has a greater sensitivity to changes in temperature and moisture.

  E. It carries signals for longer distances.

  Correct Answer: CE

• Question 1345:

  What are two behaviors of a point-to-point WAN topology? (Choose two.)

  A. It leverages a dedicated connection.

  B. It provides direct connections betwaen each router in the topology.

  C. It delivers redundancy between the central office and branch offices.

  D. It uses a single router to route traffic between sites.

  E. It connects remote networks through a single line.

  Correct Answer: AE

  A point-to-point WAN topology uses a dedicated line or circuit to connect two network devices, such as routers or switches, over a long distance. This dedicated connection is typically established by a service provider and provides a direct link between the two devices, with no intermediary network devices in between. This topology is often used to connect remote sites or branch offices to a central office or data center, and can be used for various WAN technologies such as T1/E1 lines, leased lines, or MPLS circuits.

  Option B is incorrect because a point-to-point topology only provides a direct connection between the two devices at each end of the link, not between each router in the topology. Option C is incorrect because point-to-point topologies typically do not provide redundancy between sites, as there is only one dedicated line or circuit connecting the two devices. Option D is incorrect because point-to-point topologies require two routers or devices, one at each end of the dedicated line or circuit, to route traffic between the sites.

• Question 1346:

  What is a link-local all-nodes IPv6 multicast address?

  A. ff02:0:0:0:0:0:0:1

  B. 2004:33c:94d9:431e:255::

  C. fffe:034:0dd:45d6:789e::

  D. fe80:4433:034:0dd::2

  Correct Answer: A

  An IPv6 multicast address for well-known link-local messages would start with “FF02”

• Question 1347:

  Which is a reason to implement IPv4 private addressing?

  A. Comply with PCI regulations.

  B. Reduce the size of the forwarding table on network routers.

  C. Reduce the risk of a network security breach.

  D. Comply with local law.

  Correct Answer: C

• Question 1348:

  Which signal frequency appears 60 times per minute?

  A. 1 Hz signal

  B. 1 GHz signal

  C. 60 Hz signal

  D. 60 GHz signal

  Correct Answer: C

  A signal frequency that appears 60 times per minute is a 60 Hz signal. The unit "Hz" (hertz) represents the number of cycles or oscillations per second. In this case, a signal with a frequency of 60 Hz means it completes 60 cycles or oscillations in one second.

  Since there are 60 seconds in a minute, a 60 Hz signal will complete 60 cycles per second multiplied by 60 seconds, resulting in a total of 3,600 cycles or oscillations per minute.

  To summarize, a signal frequency that appears 60 times per minute is a 60 Hz signal.

• Question 1349:

  What is a function of spine-and-leaf architecture?

  A. offers predictable latency of the traffic path between end devices

  B. mitigates oversubscription by adding a layer of leaf switches

  C. exclusively sends multicast traffic between servers that are directly connected to the spine

  D. limits payload size of traffic within the leaf layer

  Correct Answer: A

  With a spine-and-leaf architecture, no matter which leaf switch to which a server is connected, its traffic always has to cross the same number of devices to get to another server (unless the other server is located on the same leaf). This approach keeps latency at a predictable level because a payload only has to hop to a spine switch and another leaf switch to reach its destination.

• Question 1350:

  What is a characteristic of a collapsed-core network topology?

  A. It enables all workstations in a SOHO environment to connect on a single switch with internet access.

  B. It enables the core and access layers to connect to one logical distribution device over an EtherChannel.

  C. It allows wireless devices to connect directly to the core layer, which enables faster data transmission.

  D. It allows the core and distribution layers to run as a single combined layer.

  Correct Answer: D
