Question No : 5

Refer to the exhibit.
HP HP0-Y47 question 5
This HP 10500 Switch Series is receiving an average of 1 Gbps of HTTP traffic from

Question No : 9

A company needs a simple authenticate solution for guests. The HP Comware access
layer switches will implement portal authentication (or Web-Auth). The network
administrator wants the switch to host the login web page on an IP address that not used
for any other purpose.
What should the administrator do to accomplish this goal?

A. Set the IP address when defining the local portal server, and create a loopback interface for the address
B. Create RADIUS scheme that specifies this IP address for the authentication server. Select this scheme for portal authentication in the default domain
C. Create a layer 3 interface for the guest VLAN and assign the desired IP address. Activate local portal authentication on this interface.
D. Set the IP address when defining the local portal server, and the switch automatically begins using that address.


Question No : 10

Refer to the exhibit.
HP HP0-Y47 question 10
Switch 1 and switch 2 run open Shortest Path First (OSPF) on all VLANs. Both switches
establish an OSPF adjacency to a router at the main data center. Exhibit shows shoes
some virtual Routing Redundancy Protocol (VRRP) and OSPF settings on Switch 1 during
normal operation.
How can a network administrator increase the resiliency of this solution?

A. Implement Bidirectional Forwarding Detection (BFD) on the peer keep alive link between the core switches.
B. Change the VLAN 10 subnet to a /24 subnet and enable VRRP on it. Place Switch 2s link to the main data center in this subnet.
C. Make sure that, in each VRRP instance, each switch has a VRRP preempt delay of several minutes.
D. Configure Switch 1 as an OSPF graceful restart helper in VLAN 11 and Switch 2 as a helper in VLAN 10


Question No : 11

Refer to the exhibit.
HP HP0-Y47 question 11
These three routers are currently configured for BGP. They do not apply any routing policy
in terms of BGP on routes or attributes advertised to an received from peers. How can the
network administrator for Router 1 cause Router 1 to advertise 192.0.2.0/24 to Router 2
and Router 3?

A. Enable BGP routing on RAGG1
B. Add a null route to 192.0.2.0/24
C. Apply route policy 1 as an inbound policy for both peers
D. Apply route policy 1 as an outbound policy for both peers


Question No : 12

An HP Provision switch port is implementing MAC Authentication (MAC-Auth) to a RADIUS
server. A device connects to the port, and the switch submits a RADIUS Access-Request
to the server. What correctly describes how the switch determines the username and
password for the request?

A. Depending on the configuration, the switch sends the device MAC address for the username or a configured username. It sends the device MAC address for the password or a configured password
B. The switch always sends the device MAC address as the username. It always sends "provision" for the password, and this password cannot be reconfigured.
C. The switch always sends the device MAC address as the username. Depending on the configuration, the password is the device MAC address or a configured password.
D. The switch always sends the device MAC address as the username and the password, and this behavior cannot be reconfigured.


Question No : 13

Refer to the exhibit.
HP HP0-Y47 question 13
The current software on the Intelligent Resilient Framework (IRF) virtual device shown in
