CCIE R&S Practice Exam 1 – MCQsGoogle ADs Which of the following is NOT a characteristic of OSPF? Supports VLSM and CIDR Uses cost as its metric Provides fast convergence Uses hop count as its metricWhat is the main purpose of a GRE tunnel? To provide encryption for IP packets To encapsulate a wide variety of network layer protocols inside virtual point-to-point links To perform NAT translations To route IPv6 packets over an IPv4 networkWhich BGP attribute is used to prevent routing loops in a BGP autonomous system? Local Preference AS-Path Next-Hop MEDIn BGP, what is the effect of setting the Local Preference attribute? It influences the exit path for outbound traffic from the local AS It influences the entry path for inbound traffic to the local AS It determines the preferred next-hop IP address It sets the priority of the router in the BGP peering relationshipWhat is the default hold-down timer for RIP routes in a Cisco router? 30 seconds 60 seconds 180 seconds 240 secondsWhat is the purpose of the bgp dampening command in a BGP configuration? To prioritize routes with higher Local Preference To reduce the effect of route flapping To advertise only the best routes To enable load balancing across multiple pathsWhich command displays detailed information about all BGP routes in the BGP table? show ip bgp summary show ip bgp neighbors show ip bgp show ip route bgpWhich command displays OSPF routes in the routing table of a Cisco device? show ip route ospf show ip ospf route show ospf routes show route ospfIn EIGRP, what is the term for a route that satisfies the feasibility condition? Successor Feasible Successor Reported Distance Feasible DistanceWhat is the default OSPF priority value for an interface? 0 1 100 255Which protocol uses a designated router (DR) and backup designated router (BDR) on multi-access networks? RIP OSPF EIGRP BGPWhich of the following protocols is used for link-state routing in a large enterprise network? RIPv2 OSPF BGP EIGRPWhat is the primary function of HSRP in a network? To provide load balancing across multiple paths To provide redundancy for a gateway router To distribute IP addresses dynamically To perform route summarizationWhich command would you use to verify EIGRP adjacency on a router? show ip eigrp neighbors show ip eigrp adjacency show eigrp neighbors show eigrp adjacencyWhich command is used to configure a static NAT translation on a Cisco router? ip nat inside ip nat outside ip nat inside source static ip nat poolWhich protocol operates at the Network layer of the OSI model and provides connectionless communication? TCP UDP IP ICMPWhich of the following IPv6 addresses is a link-local address? 2001:0db8::1 fe80::1 ff00::1 fd00::1Which command is used to enable OSPF on a router interface? router ospf 1 network 0.0.0.0 255.255.255.255 area 0 ip ospf 1 area 0 ospf enableWhat is the main function of the BGP MED attribute? To influence the best path selection process for outbound traffic To influence the best path selection process for inbound traffic To set the preference for a particular AS path To determine the next-hop IP address for the routeWhat does the ip pim sparse-mode command enable on a router interface? Dense mode PIM Sparse mode PIM Both dense and sparse mode PIM Bidirectional PIMWhat does the term “Feasible Distance” refer to in EIGRP? The metric of the best route to reach a destination The metric of the backup route to reach a destination The sum of the reported distance and the feasible successor’s metric The distance reported by a neighbor plus the cost to reach that neighborWhich IPv6 address type is used for one-to-one communication? Multicast Anycast Unicast BroadcastWhich command verifies the current OSPF state of an interface? show ip ospf neighbor show ip ospf interface show ip interface brief show ospf stateWhich command would you use to verify the configuration of a Frame Relay subinterface? show interfaces show frame-relay pvc show frame-relay map show run interfaceIn OSPF, what is an ABR? Autonomous Boundary Router Area Border Router Area Backbone Router Autonomous Backbone RouterWhich command configures a standard access list on a Cisco router? access-list standard access-list permit access-list ip access-list standardWhat is the purpose of the MPLS label protocol LDP command in a Cisco IOS device? To enable MPLS LDP on the device To disable MPLS on the device To enable OSPF routing on the device To configure BGP on the deviceWhich command is used to redistribute OSPF routes into BGP? redistribute ospf 1 redistribute ospf into bgp bgp redistribute ospf network ospf redistributeWhat is the administrative distance of EIGRP internal routes? 90 110 120 170Which protocol does BGP use to establish and maintain neighbor relationships?
