Exam Name: Servicing HP Networking Products Exam Type: HP Exam Code: HP2-Z12 Certification HP Certified Professional Total Questions: 84 Page 1 of 31 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 flow s through the core, so it is important that networking devices located in the core introduce l ittle 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 connectivi ty 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 ne twork is operational. Unmanaged switches are intended for networks that require basic con nectivity and have little or no IT support. They are cost-effective and offer intuitive and si mple configuration. Question: 4 Which HP A Series switches provide Layer 2 functionality and a Web browser inter face 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 Exam Name: Servicing HP Networking Products Exam Type: HP Exam Code: HP2-Z12 Certification HP Certified Professional Total Questions: 84 Page 2 of 31 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, the se Layer 2 switches are connected to an RJ-45 jack and mounted on the wall. They can be pow ered by PoE or an optional 48V local power supply. The NJ1000G switch is an unmanaged switch ; the NJ2000G switch is a Web managed 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 sm all 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 sm all 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 S mall Form Factor Port (SFP). Question: 6 You are troubleshooting a connection on an HP A Series switch that has one LED p er-port. You want to know if the port is operating in the wrong duplex mode. How do you use t he LED to obtain relevant information? A. Click the Mode button until the mode LED is blinkinggreenand then check the p ort LED. B. Click the Mode button until the mode LED is yellow and then check the port LE D. C. Check if the port LED is blinking, which indicates its duplex status (while i ts 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-duple x 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 directi on 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 Exam Name: Servicing HP Networking Products Exam Type: HP Exam Code: HP2-Z12 Certification HP Certified Professional Total Questions: 84 Page 3 of 31 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 additio nal PoE . Question: 8 The exhibit shows the Power and seven-segment LEDs of an HP A Series switch. Wha t 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 cluste r 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). Answer: C Explanation: Exam Name: Servicing HP Networking Products Exam Type: HP Exam Code: HP2-Z12 Certification HP Certified Professional Total Questions: 84 Page 4 of 31 Question: 9 You are installing an SFP transceiver in an HP A Series switch's SFP port. Which steps should you perform? (Select two.) A. Connect the fiber optic cable to the SFP transceiver before installing the tr ansceiver. B. Slide the transceiver into the SFP port until the spring clips catch. C. Rotate the clasp, if present on the front of the transceiver, until it catche s the knob. D. Press and hold the spring clips on the SFP port E. Press and hold the release button below the SFP port. Answer: B,C Explanation: To install an SFP transceiver, complete the following steps: 1. Remove any fibers from the transceiver before installing it. 2. Pivot the clasp on the transceiver up until it catches a knob on the top of t he transceiver. 3. Hold the transceiver on both sides and push the transceiver into the socket u ntil it makes firm contact with the socket. You should be able to feel the top and bottom clasp release catch. Question: 10 You are servicing an HP A Series switch, which is currently using a file call my config.cfg for the startup-config. You want to preserve your new configuration changes in the switc h's startup config. Which command should you use? A. Write memory B. Save C. Save startup.cfg D. Copy running-config startup-config
Answer: D Explanation: Save with this command: copy running- config startup- config Question: 11 You check the startup-config on an HP A Series switch and find that the switch u ses myconfig.cfg as the main startup-config and has no backup config. What happens if you use the undo startup saved configuration command? A. The myconfig.cfg file is deleted, and the switch returns to factory default s ettings at the next reboot. B. The myconfig.cfg file becomes the backup startup-config, and the switch retur ns to factory default settings at the next reboot. C. The myconfig.cfg file becomes the backup startup-config, and is booted at the next reboot unless you set another main startup-config D. The myconfig.cfg file is retained in the switch's memory, but the switch retu rns to factory default settings at the next reboot Answer: D Exam Name: Servicing HP Networking Products Exam Type: HP Exam Code: HP2-Z12 Certification HP Certified Professional Total Questions: 84 Page 5 of 31 Explanation: Sometimes you will need to revert a switch to its factory-default settings, but the customer still wants to preserve the current startup- config file (or files). You can meet this requirement with one command when the switch has no backup startup- config . Simply enter the undo sa ved configuration command, which removes the main attribute from the main startup- c onfig file, but preserves the file itself. When the switch reboots, it loads the factory default settings because no main or backup startupconfig is specified. The slide displays the proper command s for meeting this requirement when the customer's switch has both a main and a backup startup - config file. (The process is complicated slightly because there is no undo savedconfig backup command.) First, move the backup attribute from the backup startup- config to the main sta rtupconfig by entering startup saved-configuration <filename> backup , specifying the filename of the main startup config . The former backup file is preserved in the flash memory but no longer plays a role in the boot process. The main startup- config file, file A, now has both the mai n and backup attributes, so you can enter reset saved-configuration backup to set the backup startupconfig to NULL without deleting the file. Finally, enter undo startup saved-configuration to take file A out of the boot process without deleting it. Now the switch will boot at the factory default settings, but the customer's configurations remain intact. Question: 12 You are troubleshooting an HP A Series switch. You attempt to log in to both the
CLI and the Web browser interface in several different ways, but you are always prompted for credentials. The customer tells you that the person who created the passwords is no longer em ployed by the company. What can you do to access the switch? A. Use the failsafe credentials, admin for username and password for password. B. Press the Reset and Clear buttons on the switch's front panel, holding them f or at least 5 seconds, to clear the password C. Access the Boot ROM menu and bypass the configuration, starting the switch at factory default settings. D. Access the switch over a direct console connection, which always permits acce ss without a password. Answer: C
