A network architect is deciding whether to use a/24 subnet or a/25 subnet for each VLAN shown in the exhibit. What is a valid reason for the architect to decide on a/24 subnet?

• A.  A/24 subnet scales better, allowing the company to add interface modules without changing the VLANs
• B.  A/24 subnet uses up fewer IP addresses than a/25 subnet and better conserves the IP addressing space
• C.  A/24 subnet provides better compatibility with IPv6 addressing, so it future proofs the solution
• D.  A/24 subnet provides enough IP addresses for the current needs, but a/25 subnet does not

A network architect is proposing an HP 6600 series router at the core of this enterprise customer network. The router runs Border Gateway Protocol (BGP) and announces the customer networks to the internet service provider (ISP). The router also runs Open Shortest Path First (OSPF) to communicate with the rest of the customer network.
What is an appropriate method for the HP 6604 router to advertise routes to the internet to the other routing switches?

• A.  The router should redistribute BGP routes into OSPF. The Area Border Routes (ABRs) should summarize those routes for advertisement in areas 1 and 2
• B.  The router should advertise a default route as an Autonomous System Router (ASBR) summary to the other routing devices in area 0
• C.  The route should redistribute BGP routes OSPF. Areas 1 and 2 should be configured as stub areas to filter out the external routes
• D.  The router should advertise BGP routes into OSPF but filter out all routes except the private network that belongs to the customer

A customer has Voice IP (VoIP) phones that support Link Layer Discovery Protocol Media Endpoint Discovery (LLDP-MED). The phase need to receive their VLAN ID using this protocol. The network architect is proposing HP 5500-48G-PoE+EI switches. Each user computer connects to the phone, which then connects to the Ethernet jack. LLDP is enabled on the switch. Each Edge port is trunk port that permits VLAN 10 (the user VLAN) and VLAN 20 (the voice VLAN).
Which other setting recommended on the edge port?

• A.  The voice VLAN is enabled
• B.  LLDP Cisco Discovery Protocol (CDP) compliance enabled
• C.  The PVID is set to VLAN 20
• D.  The LLDP voice VLAN ID is set to 20

A network architect has planned an 802.1X solution for a company with these requirements:
The company wants to keep this solution as it is but also allow the same ports to support guest access. Instead of authenticating with 802.1X, guests should log in through a Web page hosted on UAM.
Which solution meets this requirement?

• A.  The ProVision switches do not implement authentication on their ports. The IRF virtual device implements 802.1X and Web-Auth on the links that connect to the ProVision switches.
• B.  The ProVision switches implement hybrid ports for authentication. The switch port detects whether a connected device belongs to an employee or guest and implements either 802.1X or remote Web-Auth.
• C.  The ProVision switches have a guest VLAN on the ports than enforce 802.1X. The guest VLAN extends to the IRF virtual switch, which enforces Web-Auth to UAM on this VLAN.
• D.  The ProVision switches implement 802.1X and Web-Auth on the same ports. The switches have Web pages downloaded on to them and enforce Web-Auth locally.

A network architect is designing the logical topology for a campus LAN networking solution. The customer requires support for 2400 edge ports, which is provided by 10 intelligent Resilient Framework (IRF) groups at the access layer. This customer does not have a wireless network nor anticipants adding one in the next two years. However, the customer does want to authenticate users with 802.1X and use the network RADIUS server to divide users from different groups into different VLANs. The customer has three user groups, each of which includes between 600 and 900 users.
Additionally, the customer understands that the RADIUS server will require several policies but wants to keep these policies as simple and easy to maintain as possible.
How can the network architect ensure that the solution meets the customer needs and also follows best practice?

• A.  Plan a different VLAN ID and subnet address for each user group on each access layer IRF group. Either core or access layer routing will work for this solution
• B.  Plan a solution for designing dissolvable agents to the endpoints so that they can complete 802.1X authentication seamlessly
• C.  Assign a /23 subnet to each VLAN so that the VLAN can accommodate the required number of users, even if users connect multiple devices
• D.  Use access layer routing. Assign a different subnet to VLAN2 on one access layer IRF group then the VLAN2 on the another access layer group
