HP HP Certifications HP0-Y47 Questions & Answers

• Question 1:

  Refer to the exhibit.

  

  Router 4, which is an HP Comware router, redistributes Routing Information Protocol (RIP) routes into Open Shortest Path First (OSPF) process 1. Router 4 has several dozen IP routes, and the network administrator wants to minimize the number of external routes throughout the entire OSPF AS. How can the administrator meet this requirement?

  A. Create an ABR summary for the RIP routes on Router 2 and Router 3.

  B. On all OSPF devices, configure all OSPF areas, including area 0, as stub areas.

  C. On all OSPF devices in area 0, set area 0 as a not-so-stubby-area (NSSA)

  D. Create an ASBR summary for the RIP routes on Router 4.

  Correct Answer: D

  asbr-summary command to configure a summary route.

  Use the

  Use the undo asbr-summary command to remove a summary route.

  No ASBR route summarization is configured by default.

  asbr-summary command configured, an ASBR summarizes redistributed routes that fall into the specified address With the range into a single route. If the ASBR resides in an NSSA area, it advertises the summary route in a Type-7 LSA into

  the area.

• Question 2:

  Refer to the exhibits. Exhibit 1 Exhibit 2

  

  

  Exhibit 2 shows the Virtual Router Redundancy Protocol (VRRP) configuration and status for VLAN 3 on switch 1 during normal operation, when both Switch 1 and Switch 2 are up. Switch 1 then experiences a power failure. After a few

  minutes, power is restored, and the switch comes back up.

  What happens to VRRP operations in VLAN 3?

  A. Switch 1 becomes Master two minutes after its VRRP processes up.

  B. Switch 2 remains Master Switch 1 receives an error and stops participating in VRRP

  C. Switch 2 remains Master, and Switch 1 becomes a Backup router.

  D. Switch 1 becomes Master as soon as its VRRP processes come up.

  Correct Answer: C

  I think Switch2 has priority 255, because Switch2(10.1.3.2) - MAster is up during 50 min, preempt is on in VRRP So Swicth1 when comes online after 120min and trying to preeemt still bee Backup Router

• Question 3:

  Refer to the exhibit.

  

  A server connects to GigabitEthernet1/0/1 on an HP Comware switch. The server sends tagged traffic in VLAN2. It has an application that sets the DiffServ Code Point (DSCP) for its traffic to 16 and the 802.1p value to 2. The switch should use the DSCP to place the traffic in priority queue. The traffic belongs to the queue that is one priority level higher than the queue for best effort traffic (traffic without a QoS value)

  What can the network administrator do to meet this requirement?

  A. Change GigabitEthernet1/0/1's trust setting to "dot1p" set the port priority to 3. DSCP will not be used

  B. Keep Gigabit Ethernet1/0/1's QoS trust setting to "dot1p" Set the port priority to 3.

  C. Change the dot1p-lp map to map 802.1p value 2 to lp 2 and 802.1p value 0 to lp1.

  D. Change the dscp-dot1p map to map DSCP 16 to 802.1p value 1. RECEIBE priority 0

  Correct Answer: C

• Question 4:

  Refer to the exhibit.

  

  This HP 10500 Switch Series is receiving an average of 1 Gbps of HTTP traffic from 10.1.4.0/24. The switch starts to receive an additional 1 Gbps of HTTP traffic from 10.1.4.0/24. How does the switch handle the traffic?

  A. It drops the traffic

  B. It forwards the traffic but marks it yellow (for a higher drop precedence)

  C. It forwards the traffic without remarking it in any way

  D. It forwards the traffic but marks it for forwarding in a lower priority queue

  Correct Answer: C

  Parameters

  cir committed-information-rate: Specifies the committed information rate (CIR) in kbps.

  cbs committed-burst-size: Specifies the committed burst size (CBS) in bytes. The committed-burst-size argument ranges from 4000 to 16000000, the default is 4000.

  ebs excess-burst-size: Specifies excess burst size (EBS) in bytes. The excess-burst-size argument ranges from 0 to 16000000, the default is 4000.

  pir peak-information-rate: Specifies the peak information rate (PIR) in kbps.

  green action: Specifies the action to be conducted for the traffic conforming to CIR. The action argument can be:

  discard: Drops the packets.

  pass: Forwards the packets.

  remark-dscp-pass new-dscp: Marks the packets with a new DSCP precedence and forwards them to their destinations. The new-dscp argument is in the range 0 to 63.

  By default, packets conforming to CIR are forwarded.

  red action: Specifies the action to be conducted for the traffic conforms to neither CIR nor PIR. The action argument can

  be:

  discard: Drops the packets.

  pass: Forwards the packets.

  remark-dscp-pass new-dscp: Marks the packets with a new DSCP precedence and forwards them to their destinations. The new-dscp argument is in the range 0 to 63.

  By default, packets conforming to neither CIR nor PIR are dropped.

  yellow action: Specifies the action to be conducted for the traffic conforms to PIR but does not conform to CIR. The actionargument can be:

  discard: Drops the packets.

  pass: Forwards the packets.

  remark-dscp-pass new-dscp: Marks the packets with a new DSCP precedence and forwards them to their destinations. The new-dscp argument is in the range 0 to 63.

  By default, packets conforming to PIR but not conforming to CIR are forwarded.

• Question 5:

  Refer to the exhibit.

  

  A network administrator is checking the Quality of Service (QoS) settings on an HP ProVision Switch.

  This frame arrives on the switch:

  Ingress port: A1

  No 802.1Q tag

  Source IP address = 10.1.2.10

  Destination IP address = 10.1.4.4

  DSCP = 48

  Destination TCP port = 5060

  To which priority queue will the switch assign this frame? (Queues are numbered 0-7) B. 1

  C. 4

  D. 6

  Correct Answer: C

  If more than one global classification criteria, they are searched in the following order: TCP / UDP port number IP-address of the sender and receiver IP precedence value DSCP value Minutes of the third level VLAN number Incoming port switch Markings on the data link layer 802.1p When a packet is matched by several criteria, the marking is applied only for the first matched by the order

• Question 7:

  A company is implementing 802.1X authentication. These are the requirements:

  Employees who pass 802.1X authentication should be placed VLAN 3.

  Guests and employees who cannot authenticate, or fail authentication, should be placed in VLAN4.

  Different users might connect to port at different times, but only one device will connect to the port at the same time.

  802.1X is enabled Globally on the switch (aaa port-access authenticator)

  ftp://ftp.hp.com/pub/networking/software/Security-Oct2005-59906024-Chap08-PortAccess(8021x).pdf Sets the period during which the port does not try to acquire a supplicant. The period begins after the last attempt authorized by the max-requests parameter fails (next page). (Default: 60 seconds)

• Question 8:

  Refer to the exhibit. .

  

  A network administrator has begun configuring a Protocol Independent Multicast Sparse Mode (PIM-SM) solution on all of the network infrastructure devices shown in the exhibit. The administrator has selected the static method for configuring rendezvous (RPs) and wants to use 4 as RP.

  Where must the administrator configure the static RP setting?

  A. On IRF 3 and IRF 4 only

  B. On switch 1, IRF 2, IRF 3, and IRF 4

  C. On IRF 2, IRF 3, and IRF 4 only

  D. On IRF 2 and IRF 3 only

  Correct Answer: C

  http://mrncciew.com/2013/01/19/pim-sm-static-rp-configurations/

  In Static-RP configuration, you need to configure "ip pim rp-address x.x.x.x" command on every multicast enable router in your network including RP itself. In this example we will make CME as RP in this network.
