Example Questions

Which type of router can provide connectivity between areas in an IS-IS domain? Which label operation is performed by an MPLS ingress router? You are logged into a router and have navigated to the (edit routing-options] level of the hierarchy. You have been asked to create a static route that will use 10.10.10.1 as its primary next-hop and 10.10.10.5 as its secondary next-hop. Which command correctly configures this scenario? You have been asked to configure an IPv6 address for a group of interfaces that could belong on different routers. If a packet is sent to that address, it should be received by all routers in the group. Which address type would be suited for these requirements? An RSVP LSP in your network is operational but you are receiving complaints about network throughput across the LSP. You suspect that the RSVP bandwidth was omitted from the router configuration. Which operational mode command will help you verify your suspicions? You observe that VPN routes are hidden on your PE router Which situation accounts for these hidden routes? What are two valid actions that can be applied to a frame by a Layer 2 firewall filter? (Choose two) You are logged into a router and issue the command show route protocol bgp. You see that you have received the route 10 0.4/24 from two different peers Both peers were learned using IBGP and Local-Preference. MED, Origin, and AS-path are equal. Which criterion is used for this situation? An Ethernet bridge is configured such that all interfaces are in a single broadcast domain.Which two tasks does the bridge perform in response to receiving a frame with an unknown unicast destination MAC address? (Choose two.) You have configured multiple IP-IP tunnels across your network to provide connectivity to remote sites.Which technique is used to help the IP endpoints in your network determine the optimal packet size to send across your tunnels? Which action does the local router take after sending a Notification message to a remote peer? What is contained in an IS-IS CSNP message? After configuring OSPF between two routers you check for an adjacency. You see that the adjacencies are not coming up on an Ethernet segment. What are two reasons that would cause this situation? (Choose two) Which two configuration elements must match on all switches participating in the same MSTP region? (Choose two.) You are logged into a PE router participating in a Layer 3 VPN as defined in RFC 4364. You would like to ping the locally connected CE router's interface. The address of the interface is 192.168.1.1; the VPN routing-instance is named VPN-A.Which command will accomplish this task? Which two problems occur when increasing numbers of users are added to an Ethernet LAN with no switches present? (Choose two.) Which two values displayed in the output from the show spanning-tree MSTP configuration command must match on all switches participating in the same MSTP region? (Choose two) Router A receives two similar route advertisements from different BGP peers.What would cause a route to be selected in this scenario? Which statement is true of a Layer 2 circuit? In an RSTP network, which combination of port types can exist on the root bridge? You are logged into a router and issue the command show route protocol bgp. You see that you have received the route 10 0.4/24 from two different peers Both peers were learned using IBGP and Local-Preference. MED, Origin, and AS-path are equal. Which criterion is used for this situation? You have been asked to provision a service provider's network to accommodate Layer 3 VPNs as defined in RPC 4364. Which three tasks must be performed before the provider core is ready to carry VPN traffic? (Choose three.) To prevent fragmentation issues across a GRE tunnel, which MTU value is recommended for the tunnel to accommodate most IP packets? Which three functions are performed by an OSPF area border router (ABR)? (Choose three) Which Junos operational mode command is used to verify that load balancing is working as expected? Which two statements describe differences between IPv4 and IPv6? (Choose two) Which two configuration elements are defined under an MSTP instance? (Choose two) You are asked to design a Layer 2 switched topology that can automatically recover from link failures. Which type of protocol would you consider in your design? You want to influence how traffic enters your network Using industry best practices, which two BGP attributes would you modify to accomplish this goal? (Choose two) Which two BGP attributes are modified by default when they are passed between external BGP peers? (Choose two) Which IS-IS packet is used to carry routing updates? What are two benefits of using an OSPF designated router (DR)? (Choose two.) What are three valid BGP message types? (Choose three.) Which packet type does the router use to request up-to-date link-state information? Under which Junos configuration hierarchy is a load-balancing policy applied? You are logged into a PE router participating in a Layer 3 VPN as defined in RFC 4364. You would like to ping the locally connected CE router's interface. The address of the interface is 192.168.1.1; the VPN routing-instance is named VPN-A. Which command will accomplish this task? You own a small company and need to assign IPv6 addresses to your routers. Because you want to follow the guidelines spelled out in RFC 3177, you want to design your network with the correct prefixes.Which prefix would your ISP likely allocate to your company? You have been asked to use a convention that allows for auto configuration of interface addresses. You are not allowed to use DHCPv6. What do you do? Which statement is true about the operation of Layer 2 VPNs? Your area border router (ABR) receives type 1.2 and 5 link-state advertisements (LSAs) from a non-backbone area. What would the ABR do with the information learned from the non-backbone area? In an IS-IS network, which device represents the pseudo-node? What is the size of the unique address used to identify each node on an Ethernet LAN? You notice that a route from internal BGP peer 192.168.1.1 is missing from the local route table.Which two commands would be used to help identify the source of the problem? (Choose two.) You have been asked to define a default gateway for traffic leaving a router. This route should use interface so-0/0/0 as its next-hop.Which type of route would be suited for this scenario? You must configure an OSPF area that does not accept type 3 link-state advertisements (LSAs) from area 0 (other than the default route) You have configured your area to be stub, but you still see type 3 LSAs. What will account for this behavior? Which BGP state denotes a fully operational session? Which IS-IS packet is used to determine the level of an IS-IS neighbor? You have a stub OSPF area running in your network. Your supervisor has asked you to build a virtual link across this area to connect new equipment acquired in a recent ISP acquisition.Which statement is correct about this scenario? Which two statements about BGP are accurate? (Choose two.) Your customer complains that their Layer 3 VPN is not passing traffic from one site to another. You assigned that customer to VPN-A.Which command on the PE router will confirm the presence of customer routes?
