HPE Networking Comware (HPE6-A89) Certification Sample Questions

01. PIM-SM is enabled on all routers. The engineer configured static-rp 10.0.0.1 in PIM view only on the router that owns 10.0.0.1, and receivers on other routers never get the group's traffic. What is the fix?
a) Enable PIM dense mode on the RP's interfaces
b) Enable IGMP on the RP's loopback interface
c) Configure the same static RP address on every PIM-SM router

02. Five routers share one Ethernet segment in area 0. Which router describes this segment in a Type 2 network LSA?
a) Every router on the segment, each in its own LSA
b) The DR for the segment
c) The ABR that joins area 0 to other areas

03. The fabric reports a problem on one of its IRF links. The engineer needs each member's IRF port state and which members are adjacent. Which command shows this?
a) display irf topology
b) display irf
c) display irf configuration

04. Hosts in VLAN 20 (10.20.0.0/24) must not reach a server in VLAN 10, and a Comware switch routes between the VLANs. The engineer applies an advanced ACL that denies source 10.20.0.0/24 as an inbound packet filter on VLAN-interface 10, but the hosts still reach the server.
Where should the ACL be applied?
a) Outbound on VLAN-interface 20
b) Inbound on VLAN-interface 20
c) Inbound on the server's access port in VLAN 10

05. R1 runs ospf 1 and R2 runs ospf 100. Their shared interfaces are in area 0 with matching settings. Will they become OSPF neighbors?
a) No, since neighbors must use the same process ID
b) Only if one of the two routers is configured as an ABR
c) Yes, since the process ID matters only on the local router

06. An engineer has created a traffic classifier that matches video traffic and a traffic behavior that sets a rate limit. Neither is in effect yet. What is the next step?
a) Create a QoS policy that pairs the classifier with the behavior
b) Apply the traffic behavior directly to the interface
c) Reference the classifier from inside the traffic behavior

07. Voice frames leave the access switch with 802.1p priority 5. After a routed hop on the core switch, they are treated as ordinary traffic. What explains this, and which marking should the design rely on?
a) The core must carry voice on a trunk so that the tag is preserved
b) Priority 5 is outside the range the core accepts, so re-mark voice as 802.1p 7
c) 802.1p lives in the VLAN tag, which a routed hop rebuilds, so rely on DSCP

08. In a PIM-SM network, receivers first get a group's traffic through the RP. Later, the traffic stops passing through the RP and follows a more direct path from the source. What has happened?
a) The source's DR has stopped registering, so the RP is bypassed
b) The receiver-side DR has switched from the RPT to the SPT rooted at the source
c) The RP has failed, and PIM-SM has fallen back to dense mode flooding

09. R1 and R2 share a link in area 20. Area 20 is configured as a stub on R1 but not on R2. Every other OSPF setting matches, and the routers never form an adjacency. What is the cause?
a) Their router IDs differ, and router IDs must match on a shared link
b) Stub areas do not support adjacencies on multi-access links
c) The two routers disagree on whether area 20 is a stub

10. A branch uplink connects to a provider that accepts at most 20 Mbps and drops anything above that. Branch traffic is bursty, and the team wants to lose as few packets as possible during bursts.
Which mechanism should be applied on the uplink?
a) Traffic shaping (GTS) on outgoing traffic
b) Priority mapping on incoming traffic
c) Traffic policing (CAR) on outgoing traffic
