You are in the process of replacing Cisco switches at the distribution layer with HP A-Series switches. You have connected the A-Series switches in parallel with the existing Cisco switches at the distribution level, edge, and core. The HP A-Series switches are configured for Intelligent Resilient Framework (IRF) and the VLAN interfaces have been assigned an unused IP address for the router address. You now want the A-Series switches to assume routing responsibilities for one of your network four VLANs. Youaddress for the router address. You now want the A-Series switches to assume routing responsibilities for one of your network? four VLANs. You alter the DHCP scope to reflect the new gateway IP address. What should you verify before beginning this step?
that HP A-Series switches have all necessary routes to non-directly connected networks
Two BGP routers, the "local" and "the remote," are connected to a switch. An EBGP session is established between them. What will happen if an Ethernet interface is disconnected on the local BGP router? (Select two.)
On the local router, all BGP sessions are terminated, and all IP routes from that BGP neighbor are removed from the routing table. On the remote side, the BGP router wait for the hold time timer before ending the BGP session.
If the routers are using BFD, the remote BGP router will quickly detect forwarding path failures and remove all IP routes from the routing table.
You want to add HP edge switches to a company's Cisco network. Distribution Cisco switches are set as the Rapid PVST+ root and secondary root. You connect HP A-Series switches that are running their factory default configuration to the two Cisco distribution switches. What will happen?
Cisco distribution switches send untagged standard BPDUs to HP switch in VLAN 1, which the HP switch forwards to the other distribution switch, preventing a loop. The HP switch drops all tagged data frames.
A provider of MPLS services configures MPLS Layer-3 VPN services for three customers. Each customer has three branch offices that will be interconnected by MPLS Layer-3 VPNs. One customer is advertising their IP prefixes between sites using BGP. This customer establishes a backup link directly connecting Site-1 to Site-2. Which BGP attribute can the provider use to prevent routing update loops in the MPLS network?
You are connecting an HP A-Series switch to the edge of an existing Cisco LAN that is running RapidPVST+. Cisco distribution switches are the root and secondary root in all VLANs. The long pathcost method is enabled on all Cisco switches, and the cost of the ports between the distribution switches is set to 10000. Gigabit Ethernet uplinks are configured as dot1q trunks and 2 all VLANs are permitted. You enable MSTP on the HP A-Series edge switch.What is the topology and Spanning Tree functionality? (Select two.)
HP A-Series edge switch receives standard BPDU in VLAN 1. The uplink connected to the root switch is root port, the other uplink port is not blocked.
PVST+ BDPUs are forwarded by the HP edge switch because both uplinks are up.
What is a characteristic of load balancing in RRPP?
multiple RRPP domains sharing the same ring
A company has a network with Cisco switches that implement PVST+ but wants to migrate to MSTP, which all of its switches support. What is your first step for starting the migration from PVST+ to MSTP?
Configure MSTP options on all switches: Name, region, VLAN to instances mapping.
RRPP statistics for an HP A-Series switch indicate that Hellos are being received on the secondary port but do not indicate that Hellos are being sent on the primary port. What most likely caused this?
The switch is in Transit node mode.
A company has a Cisco network that runs CDP. What would happen if you connect a new HP A- Series switch that runs LLDP to this network?
The new switch does not support CDP. It will forward the CDP frames it receives. Two Cisco switches connected to the new switch will "see" each other as CDP neighbors.
Which statement is true about BGP Route Refresh? (Select two.)
Route Refresh is advertised as a BGP capability to BGP neighbors during BGP session establishment.
BGP Route Refresh eliminates the need for a Hard Reset of the BGP connection with a BGP neighbor when route policies are changed.
A company's Cisco network runs VTP. VTP is set in Server mode on distribution switches and in Client mode on edge switches. To prepare for the insertion of HP switches at the edge of the company's network, what should you do?
Change VTP mode to Transparent on all Cisco switches.
A company's Cisco network is configured with PVST+, and the distribution switches are the root and secondary roots in the existing VLANs. You want to migrate the company's network to implement MSTP. What will be your first step in performing the migration?
Verify the Cisco switches and their IOS support MSTP.
The Cisco network of a company is EIGRP-based. Currently, the routers include both internal and external EIGRP networks. OSPF will be added on all routers, including OSPF 'network' and 'redistribution' commands. All routers are using default administrative distances.Which types of routes will be found in the IP routing tables?
internal EIGRP and external OSPF networks
In a LAN equipped fully with Cisco switches, you want to remove Cisco Discovery Protocol (CDP) and replace it with Link Layer Discovery Protocol (LLDP). What should you check before proceeding? (Select two.)
whether the Cisco IOS of all switches support LLDP
whether IP phones are connected to the switches and if they support LLDP-MED
You are migrating a customer's distribution layer from Cisco Catalyst 3750 switches to HP E8200 zl Series switches. You are now planning the Layer 3 migration.The Cisco switches use Hot Standby Router Protocol (HSRP), and the HP switches will use Virtual Router Redundancy Protocol (VRRP) to function as redundant default gateways for the LAN's subnets.You talk with the customer and determine that you will not be able to gain access to other network solutions such as DHCP servers nor firewalls and other security devices. Which general method should you select for migrating routing functionality?
Configure VRRP on the HP switches using the same HSRP virtual addresses; disable the Cisco switch VLAN interfaces at the same time that you enable VRRP on the corresponding HP switch interfaces.
You are migrating a customer's distribution layer from Cisco Catalyst 3560 switches to HP A7500 Series switches. You are now planning the Layer 3 migration.The Cisco switches use Hot Standby Router Protocol (HSRP) and the HP switches will use Intelligent Resilient Framework (IRF), which will allow the multiple switch stack to function as redundant default gateways for the LAN's subnets.You talk with the customer and determine that you will not be able to gain access to other network systems such as DHCP servers nor firewalls and other security devices.Which general method should you select for migrating routing functionality?
Configure the VLAN IP addresses on the IRF configured HP switches using the same HSRP virtual addresses; disable the Cisco switch VLAN interfaces at the same time that you enable the corresponding VLAN interface on the master IRF HP switch.
You want to enable RRPP on interface Gigabit Ethernet 1/0/4 of an HP A-Series switch. Which commands should be configured on this interface? (Select two.)
port link-type trunk
You intend to install HP switches on an existing Cisco network. To prepare the progressive replacement of Cisco edge switches with HP switches, you want to implement LLDP on the current Cisco network. The Cisco distribution switches support LLDP. However, the Cisco edge switches are of different models running various IOS and may not support LLDP. Some IP phones may only use CDP. What should you do?
Run CDP and LLDP in parallel on distribution and edge switches where allowed.
View a network diagram and two switch configurations. 9 After you issue the command irf-port-configuration active on HP A5800 Switch members 4 and 5, the 10 Gigabit Ethernet link 1/0/25 is connected. What is the expected result?
IRF Member 5 becomes the Master.
You are in the process of replacing Cisco switches at the distribution layer with HP A-Series switches. You choose a migration strategy of connecting the A-Series switches in parallel with the distribution switches. You have also migrated the edge switches?connections to the new A-Series switches, and the new distribution switches have assumed all routing functionality. You are ready to remove the Cisco distribution switches. Which Cisco proprietary protocol was used to distribute VLAN definitions in the original network and must be migrated to an open standard equivalent before completing this step?
VLAN Trunking Protocol (VTP)
On a company's Cisco network, VLANs are learned through VTP. On the edge switches, allowed VLANs on VLAN trunks are restricted to VLANs that contain end nodes. This reduces the number of required PVST+ instances, reducing processing on the switch. To support your goal of migrating to open standards protocols, you decide to remove VTP.Which steps are required to do this? (Select three.)
You set VTP to Transparent mode.
On each switch, you configure only the required VLANs.
You configure trunk ports with all VLANs permitted. This will not increase PVST+ instances because only the required VLANs are configured on the switch.
