Question: 1
|
Which area of the network is
considered the backbone?
A. data center
B. core
C. distribution layer
D. LAN access layer
|
Answer: B
|
Explanation:
The core is the backbone of
the network, a central or common point where traffic flows between users, their
workgroups, and shared resources. Most inter-workgroup traffic flows through
the core, so it is important that networking devices located in the core introduce
little or no delay (latency). Core switches are usually wirespeed , highly
available devices.
|
Question: 2
|
Which device forwards network
traffic based only on Layer 2 information?
A. router
B. switch
C. hub
D. firewall
|
Answer: C
|
|
Question: 3
|
Which switch is specifically
designed for networks that require basic connectivity and have little or no IT
support?
A. fixed-port switch
B. light Layer 3 switch
C. modular switch
D. unmanaged switch
|
Answer: D
|
Explanation:
Unmanaged switch-A switch that
enables Ethernet devices to communicate but does not have a management
interface. You simply connect the switch to other devices, and the network is
operational. Unmanaged switches are intended for networks that require basic
connectivity and have little or no IT support. They are cost-effective and
offer intuitive and simple configuration.

Question: 4
|
Which HP A Series switches
provide Layer 2 functionality and a Web browser interface but no CLI?
A. HP A5800 Series switches
B. HP NJ2000GIntelliJack
switches
C. HP A3600-E1 Series switches
D. HP A3100 Series switches
|
Answer: B
|
Explanation:
The HP IntelliJack Switch
Series is designed to increase network connections and provide support for
legacy analog and digital devices. Deployed at the access layer, these Layer 2
switches are connected to an RJ-45 jack and mounted on the wall. They can be
powered by PoE or an optional 48V local power supply. The NJ1000G switch is an
unmanaged switch; the NJ2000G switch is a Webmanaged switch. The NJ100G and
NJ2000G switches provide the following:

Question: 5
|
Several HP A Series switches
are distinguished by a dual-personality (or combo) port. What is an accurate
description of this port?
A. It can accept either
Ethernet Base-T cable or fiber optic cable
B. It can accept either
Ethernet Base-T cable or a small form-factor pluggable (SFP) transceiver
C. It is a pair of ports. One
accepts Ethernet Base-T cable and one accepts a small form-factor pluggable
(SFP) transceiver. Both can be used simultaneously.
D. It is a pair of ports. One
accepts Ethernet Base-T cable and one accepts a small form-factor pluggable
(SFP) transceiver. Only one can be used at a time.
|
Answer: B
|
Explanation:
Dual-personality port -this
port can be used as either a 10/100/1000 port or a Small Form Factor Port
(SFP).
|
Question: 6
|
You are troubleshooting a
connection on an HP A Series switch that has one LED per-port. You want to know
if the port is operating in the wrong duplex mode. How do you use the LED to
obtain relevant information?
A. Click the Mode button until
the mode LED is blinkinggreenand thencheck the port LED.
B. Click the Mode button until
the mode LED is yellow and thencheck the port LED.
C. Check if the port LED is
blinking,which indicates its duplex status (while its color indicates speed).
D. Check the color of the port
LED, which indicates its duplex status (while its blinking indicates speed).
|
Answer: B
|
Explanation:
You can use the Mode button to
check the duplex mode of each port. Press the button until the Mode LED
displays yellow. In Duplex Mode, a Port LED displays green if the port is
operating in full-duplex mode (meaning data can be transmitted in two
directions simultaneously). The Port LED displays yellow if the port is
operating in half-duplex mode (meaning data can be transmitted in one direction
at a time).
|
Question: 7
|
You are installing an HP A
Series switch that requires a backup power supply as well as extra power for
Power over Ethernet (PoE) devices. Which device should you connect to this
switch?
A. RPS 1200 A
B. RPS 1000 A3
C. RPS 800 A
D. RPS500 A3
|
Answer: B
|
Explanation:
Customers can use one of three
RPSs with A Series switches:
RPS 1000 A3
RPS 800 A
RPS 500 A3 In addition to
providing redundancy, the RPS 1000 A3 provides additional PoE .
|
Question: 8
|
The exhibit shows the Power
and seven-segment LEDs of an HP A Series switch. What is the switch's status?
Exhibit:
A. The switch has member ID 8
in the cluster.
B. The switch has member ID 8
in the cluster, but its attempt to join the cluster has failed.
C. The switch has failed the
power on self test (POST) with ID 8.
D. Port number 8 has failed
the switch's power on self test (POST).
