- B . Time synchronization algorithms do not account for clock drift
- C . Client synchronizes among a set of distributed time servers.
- D . Client makes sudden changes in time to keep synchronized.
How is a switch different from a hub?
- A . A switch operates at a lower, more efficient layer of the OSI model.
- B . A switch decreases the number of broadcast storms.
- C . A switch tracks MAC addresses of all connected devices.
- D . A switch does not include any latency into the frame transfer time.
Which type of route is often used to direct traffic bound for the Internet?
- A . Redistributed
- B . Directly connected
- C . Dynamic
- D . Default
Root bridge Switch A is connected to Switch B. They are connected using the same corresponding interfaces Gi1/01 and Gi1/0/2 on both sides.
Which interface becomes a root port?
- A . Switch A Gi1/0/1
- B . Switch A Gi1/0/2
- C . Switch B Gi1/0/1
- D . Switch B Gi1/0/2
A technician wants to allow SSH connections to authenticate using an external server. If the external server becomes unreachable, the users created on the switch should be allowed.
What command will accomplish this goal?
- A . AAA authentication login default radius local
- B . AAA authentication ssh default radius enable
- C . AAA authentication login default local radius
- D . AAA authentication ssh default radius none
A technician implements a new copper connection to Gi2/0/20.
Which command should be used to check the cable length?
- A . test tdr copper-length gigabitethernet 2/0/20
- B . test copper-length tdr gigabitethernet 2/0/20
- C . test tdr copper-port gigabitethernet 2/0/20
- D . test copper-port tdr gigabitethernet 2/0/20
What does the blinking yellow Activity/PoE LED indicate on an N-Series switch?
- A . There is no current transmit/receive activity and PoE power is off.
- B . There is no current transmit/receive activity and PoE power is on.
- C . There is current transmitting/receiving and PoE power is on.
- D . There is current transmitting/receiving and PoE power is off.
A network administrator is troubleshooting an OSPF routing issue. There are two paths to a destination network from one switch. In addition, one path is comprised of four 1 Gb links.
The other path is comprised of two 1 Gb and two 100 Mb links. The administrator ran several trace routes and notices that the packets are swapping back and forth between the two paths.
Which corrective action must be taken on the switch infrastructure to correct this issue?
- A . Manually specify the OSPF Router ID on each switch within the path.
- B . Break the paths into multiple OSPF areas.
- C . Change the reference speed used by OSPF in cost calculations on all switches within the path.
- D . Switch all routing protocols to RIPv2.
What accurately describes an ICMP error message?
- A . ICMP error message will be generated for a datagram having a multicast address
- B . ICMP error message will not be generated for a datagram having an address of 127.0.0.0
- C . ICMP error message will be generated for a fragmented datagram that is not the first fragment
- D . ICMP error message will be generated in response to a datagram carrying an ICMP error message
Two N3024F switches are directly connected using 10GBASE-SR transceivers and 10 foot fiber patch cables. The ports on both sides are NOT linking.
What are two possible reasons for this issue? (Choose two.)
- A . The fiber connectors are inverted.
- B . The transceivers are on SFP ports.
- C . The fiber length is too short.
- D . The connection is using multimode fiber.
- E . The fiber is unidirectional.
