1. 1On an HPE 5945 switch, an administrator wants a display command to show the first line matching a pattern and every line after it. Which output filter should be used?

   1. A.beginCorrect answer: A
   2. B.include
   3. C.exclude
   4. D.by-linenum

   Explanation: The command reference states: "begin: Displays the first line matching the specified regular expression and all subsequent lines." The include and exclude filters select matching or nonmatching lines, whereas by-linenum adds line numbers.

2. 2A 5945 switch user role permits the vlan command but its resource policy allows access only to VLAN 10. Which VLAN can the user create with that command?

   1. A.Only VLAN 10 under that role.Correct answer: A
   2. B.Any VLAN in the switch database.
   3. C.Only VLAN 1 under that role.
   4. D.No VLAN, even VLAN 10.

   Explanation: HPE's example says, "a user role has access to the vlan command and access only to VLAN 10. When the user role is assigned, you can use the vlan command to create VLAN 10 and enter its view. However, you cannot create any other VLANs." The command and resource permissions both apply.

3. 3Which HPE 5510 HI port link type is limited to one VLAN and sends that VLAN's packets untagged?

   1. A.Access port.Correct answer: A
   2. B.Trunk port.
   3. C.Hybrid port.
   4. D.Layer 3 routed port.

   Explanation: The guide says, "Access—An access port can forward packets from only one VLAN and send these packets untagged." Trunk and hybrid ports can carry multiple VLANs.

4. 4How can DHCP clients obtain configuration from a DHCP server on another subnet?

   1. A.Use a DHCP relay agent between the client and server.Correct answer: A
   2. B.Require the client broadcast to cross routers unchanged.
   3. C.Use DHCP snooping alone as the cross-subnet relay.
   4. D.Use DHCP server proxy with DHCP relay disabled.

   Explanation: HPE states, "The DHCP clients can also obtain configuration parameters from a DHCP server on another subnet through a DHCP relay agent." A relay carries the DHCP exchange across the subnet boundary.

5. 5How do spanning tree protocols prevent loops in a physically redundant switched network?

   1. A.By selectively blocking redundant links.Correct answer: A
   2. B.By blocking all links permanently.
   3. C.By forwarding on every redundant link.
   4. D.By blocking only nonredundant links.

   Explanation: HPE says, "Spanning tree protocols eliminate loops in a physical link-redundant network by selectively blocking redundant links and putting them in a standby state." This preserves physical redundancy without forwarding loops.

6. 6What does IRF do with multiple physical switches at the same layer?

   1. A.Virtualizes them into one fabric.Correct answer: A
   2. B.Keeps every switch as an independent fabric.
   3. C.Combines ports within only one member switch.
   4. D.Requires each member to be managed separately.

   Explanation: The guide says, "The Intelligent Resilient Framework (IRF) technology virtualizes multiple physical devices at the same layer into one virtual fabric."

7. 7A 5945 switch needs an ACL rule that matches both IPv4 destination address and TCP destination port. Which ACL type provides the relevant Layer 3 and Layer 4 criteria?

   1. A.Advanced IPv4 ACL.Correct answer: A
   2. B.Basic IPv4 ACL.
   3. C.Layer 2 MAC ACL.
   4. D.IPv6 basic ACL.

   Explanation: The advanced IPv4 ACL row lists "Source IPv4 address, destination IPv4 address, packet priority, protocol number, and other Layer 3 and Layer 4 header fields." Basic IPv4 ACLs match source IPv4 addresses.

8. 8In a 5945 QoS policy, which component defines the criteria that packets must match?

   1. A.Traffic class.Correct answer: A
   2. B.Traffic behavior.
   3. C.Queue scheduler.
   4. D.Traffic shaping rate.

   Explanation: HPE states, "Traffic class—Defines criteria to match packets." A traffic behavior specifies actions on matched packets.

9. 9Without route reflection, where does BGP advertise a route learned from an IBGP peer under the guide's normal advertisement rules?

   1. A.Only back to the IBGP peer that sent it.
   2. B.To all IBGP peers, but never EBGP peers.
   3. C.To EBGP peers, rather than other IBGP peers.Correct answer: C
   4. D.To every peer regardless of its AS.

   Explanation: HPE states, "BGP advertises routes learned from an IBGP peer to EBGP peers, rather than other IBGP peers." Route reflection is a separate mechanism.

10. 10In PIM dense mode, what happens to branches without downstream receivers after multicast traffic is flooded?

    1. A.They remain in the tree without a prune.
    2. B.They are pruned from the forwarding tree.Correct answer: B
    3. C.They are immediately grafted without new receivers.
    4. D.They continue forwarding permanently.

    Explanation: The guide says, "Branches without downstream receivers are pruned from the forwarding trees." Dense mode initially floods multicast data.
