Which statement about route distinguishers in an MPLS network is true?

• Route distinguishers allow multiple instances of a routing table to coexist within the edge router.
• Route distinguishers are used for label bindings.
• Route distinguishers make a unique VPNv4 address across the MPLS network.
• Route distinguishers define which prefixes are imported and exported on the edge router.

Which protocol is used in a DMVPN network to map physical IP addresses to logical IP addresses?

• BGP
• LLDP
• EIGRP
• NHRP

A CoPP policy is applied for receiving SSH traffic from the WAN interface on a Cisco ISR4321 router.However, the SSH response from the router is abnormal and stuck during the high link utilization. Theproblem is identified as SSH traffic does not match in the ACL. Which action resolves the issue?

• Rate-limit SSH traffic to ensure dedicated bandwidth.
• Apply CoPP on the control plane interface.
• Increase the IP precedence value of SSH traffic to 6.
• Apply CoPP on the WAN interface inbound direction.

What are the two prerequisites to enable BFD on Cisco routers? (Choose two)

• A supported IP routing protocol must be configured on the participating routers.
• OSPF Demand Circuit must run BFD on all participating routers.
• ICMP must be allowed on all participating routers.
• UDP port 1985 must be allowed on all participating routers.
• Cisco Express Forwarding and IP Routing must be enabled on all participating routers.

Which list defines the contents of an MPLS label?

• 20-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
• 32-bit label; 3-bit traffic class; 1-bit bottom stack; 8-bit TTL
• 20-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit
• 32-bit label; 3-bit flow label; 1-bit bottom stack; 8-bit hop limit

Which Cisco VPN technology can use multipoint tunnel, resulting in a single GRE tunnel interface on the hub, to support multiple connections from multiple spoke devices?

• DMVPN
• GETVPN
• Cisco Easy VPN
• FlexVPN

Which feature minimizes DoS attacks on an IPv6 network?

• IPv6 Binding Security Table
• IPv6 Router Advertisement Guard
• IPv6 Prefix Guard
• IPv6 Destination Guard

Refer to the exhibit.An OSPF neighbor relationship between R2 and R3 is showing stuck in EXCHANGE/EXSTART state. The neighbor is established between R1 and R2. The network engineer can ping from R2 to R3 and vice versa, but theneighbor is still down. Which action resolves the issue?

• Restore the Layer 2/Layer 3 conectivity issue in the ISP network.
• Match MTU on both router interfaces or ignore MTU.
• Administrative 'shut then no shut' both router interfaces.
• Enable OSPF on the interface, which is required.

In which two ways does the IPv6 First-Hop Security Binding Table operate? (Choose two.)

• by IPv6 routing protocols to securely build neighborships without the need of authentication
• by the recovery mechanism to recover the binding table in the event of a device reboot
• by IPv6 HSRP to make sure neighbors are authenticated before being used as gateways
• by various IPv6 guard features to validate the data link layer address
• by storing hashed keys for IPsec tunnels for the built-in IPsec features

Refer to the exhibit.The administrator noticed that the connection was flapping between the two ISPs instead of switching to ISP2 when the ISP1 failed. Which action resolves the issue?

• Include a valid source-interface keyword in the icmp-echo statement.
• Reference the track object 1 on the default route through ISP2 instead of ISP1.
• Modify the static routes to refer both to the next hop and the outgoing intertace.
• Modify the threshold to match the administrative distance of the ISP2 route.
