A Virtual Output Queue (VOQ) is the technique used in input-queued switches where rather than keeping all traffic in a single queue, separate queues are maintained for each possible output location. It addresses a common problem known as head-of-line blocking. In VOQ each input port maintains a separate queue for each output port. It has been shown that VOQ can achieve 100% throughput performance with an effective scheduling algorithm. This scheduling algorithm should be able to provide a high speed mapping of packets from inputs to outputs on a cycle-to-cycle basis Reference: https://en.wikipedia.org/wiki/Virtual_Output_Queues

The HP IMC User Access Management (UAM) Module supports user identity authentication based on access policies associated with infrastructure resources. Reference: Intelligent Management Center User Access Management Softwarehttp://h17007.www1.hp.com/us/en/networking/products/network-management/IMC_UAM_Software/index.aspx#.VYeq3vmqpBc

LLDP must be enabled on this Ethernet ports and are configured to advertise the voice VLAN ID and QoS information using the Network Policy LLDP TLV. Reference: Application Notesfor using Link Layer Discovery Protocol (LLDP) with HP ProCurve Switches and Avaya IP Telephones - Issue 1.0http://h17007.www1.hp.com/docs/interoperability/Avaya/ProCurve-lldp.pdf

You can associate a route policy to a BGP peer. Route policies use route maps to control or modify the routes that BGP recognizes. You can configure a route policy for inbound or outbound route updates. Incorrect:Not B: Null 0 routing is used to prevent routing loops in some conditions as if any packet is destinated for some specific route in that subnet which is not available for an example is down due to any reason instead of going through the default route and packet reaching somewhere else packet destined for that specific route within that subnet must be dropped.So basically NULL 0 creates a block hole where if packets are matched is dropped. Reference: Configuring Advanced BGPhttp://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/5_x/nx-os/unicast/configuration/guide/l3_cli_nxos/l3_advbgp.html

* The Device Link Detection Protocol (DLDP) can detect the link status of a fiber cable or twisted pair. Upon detecting a unidirectional link, DLDP shuts down the faulty port automatically or prompts the user to do so manually depending on the configuration to avoid forwarding problems. * As a link layer protocol, DLDP can identify remote devices, detect unidirectional links, and shut down unreachable ports at the link layer. /  If both ends of a link are operating normally at the physical layer, DLDP detects whether the link is correctly connected at the link layer and whether the two ends can exchange packets properly. This is beyond the capability of the auto-negotiation mechanism at the physical layer. / In conjunction with the physical layer auto-negotiation mechanism where physical signals and faults can be detected, DLDP can detect and shut down physically/logically unidirectional links. 2  DLDP Implementation Reference: DLDP Technology White Paperhttp://www.h3c.com/portal/Products___Solutions/Technology/LAN/Technology_White_Paper/200812/623012_57_0.htm

The line rate of a physical interface specifies the maximum rate of incoming packets or outgoing packets. Note: Configuring the line ratePerform the following steps:Enter system view by using the following command:system-view  Enter interface view. interface interface-type interface-number  Configure the line rate for the interface. Use the following command:qos lr outbound cir committed-informationrate [ cbs committed-burst-size [ ebs excessburst- size ] ]  Reference: HP 6600 Router Series - Configuring Traffic Policing/Traffic Shaping/Line Ratehttp://h20564.www2.hp.com/hpsc/doc/public/display?docId=emr_na-c03146192&sp4ts.oid=5179297#N101D6

In a modern Clos topology, every lower-tier switch is connected to each of the top-tier switches in a full-mesh topology. If there isn't any oversubscription taking place between the lower-tier switches and their uplinks, then a non-blocking architecture can be achieved. The advantage of the Clos network is you can use a set of identical and inexpensive devices to create the tree and gain high performance and resilience that would otherwise cost must more to construct. To prevent any one uplink path from being chosen, the path is randomly chosen so that the traffic load is evenly distributed between the top-tier switches. If one of the top tier switches were to fail, it only slightly degrades performance through the data center. Reference: Clos Networks: What's Old Is New Again, What goes around, comes around – Clos Networks are backhttp://www.networkworld.com/article/2226122/cisco-subnet/clos-networks--what-s-old-is-new-again.html

Incorrect Not B: No certificate is required.Not C, D: . Specifying the URL for Web-Auth Pages That Are Stored on an External Web Server     Under External Web Pages, specify the correct URL for each page.  a. In the Login Page URL field, specify the URL of the login page, which users see when they try to access a Web site. For example, you might enter a URL such as http://192.168.1.1/login.html or http:// www.yourcompany.com/login.html. b. In the Welcome Page URL field, specify the URL of the welcome page that users see if they log in successfully.  c. In the Failed Page URL, specify the URL of the page that users see if they do not enter a valid username and password or if a RADIUS server is unavailable. Reference: Web Authentication for Mobile Usersftp://ftp.hp.com/pub/networking/software/08-C05-WebAuth.pdf
