2021 Jun 400-101 Study Guide Questions:

Q511. Refer to the exhibit. 


What does "(received-only)" mean? 

A. The prefix 10.1.1.1 can not be advertised to any eBGP neighbor. 

B. The prefix 10.1.1.1 can not be advertised to any iBGP neighbor. 

C. BGP soft reconfiguration outbound is applied. 

D. BGP soft reconfiguration inbound is applied. 

Answer: D 

Explanation: 

When you configure bgp soft-configuration-inbound, all the updates received from the neighbor will be stored unmodified, regardless of the inbound policy, and these routes appear as “(received-only).” 


Q512. Which two statements are true about OTV? (Choose two.) 

A. It relies on flooding to propagate MAC address reachability information. 

B. It uses a full mesh of point-to-multipoint tunnels to prevent head-end replication of multicast traffic. 

C. It can work over any transport that can forward IP packets. 

D. It supports automatic detection of multihoming. 

Answer: C,D 

Explanation: 

The overlay nature of OTV allows it to work over any transport as long as this transport can forward IP packets. Any optimizations performed for IP in the transport will benefit the OTV encapsulated traffic. As part of the OTV control protocol, automatic detection of multihoming is included. This feature enables the multihoming of sites without requiring additional configuration or protocols

Q513. Which two statements about SNMP are true? (Choose two.) 

A. SNMPv3 provides privacy and access control. 

B. All SNMP versions use get, getNext, and getBulk operations. 

C. SNMPv3 uses encrypted community strings. 

D. SNMPv1 and SNMPv2c use plaintext community strings. 

E. All SNMP versions support bulk retrieval and detailed error messages. 

Answer: A,B

Q514. In a nonbackbone OSPF area, all traffic that is destined to the Internet is routed by using a default route that is originated by the ABR. Which change in the configuration of the OSPF area type causes traffic from that area that is destined to the Internet to be dropped? 

A. The OSPF area changes from NSSA to totally stubby area. 

B. The OSPF area changes from NSSA to regular area. 

C. The OSPF area changes from stub area to totally stubby area. 

D. The OSPF area changes from stub area to NSSA. 

Answer: D 

Explanation: 

The ABR for the NSSA generates the default route, but not by default. To force the ABR to generate the default route, use the area <area id> nssa default-information originate command. The ABR generates a Type 7 LSA with the link-state ID 0.0.0.0 and is advertised inside the NSSA. This default route will be propagated inside the NSSA as Type 7 LSA

Q515. Which statement about the function of poison reverse in EIGRP is true? 

A. It tells peers to remove paths that previously might have pointed to this router. 

B. It tells peers to remove paths to save memory and bandwidth. 

C. It provides reverse path information for multicast routing. 

D. It tells peers that a prefix is no longer reachable. 

Answer: A 

Explanation: 

Poison Reverse in EIGRP states: “Once you learn of a route through an interface, advertise it as unreachable back through that same interface”.

Q516. Which two statements about 802.1Q tunneling are true? (Choose two.) 

A. It requires a system MTU of at least 1504 bytes. 

B. The default configuration sends Cisco Discovery Protocol, STP, and VTP information. 

C. Traffic that traverses the tunnel is encrypted. 

D. It is supported on private VLAN ports. 

E. MAC-based QoS and UDLD are supported on tunnel ports. 

F. Its maximum allowable system MTU is 1546 bytes. 

Answer: A,E

Q517. Which IP SLA operation type is enhanced by the use of the IP SLAs Responder? 

A. DNS 

B. HTTP 

C. ICMP Echo 

D. UDP Echo 

Answer: D 

Explanation: 

Figure 1. UDP Echo Operation 


Response time (round-trip time) is computed by measuring the time taken between sending a UDP echo request message from Device B to the destination device--Device A--and receiving a UDP echo reply from Device A. UDP echo accuracy is enhanced by using the IP SLAs Responder at Device A, the destination Cisco device. If the destination device is a Cisco device, then IP SLAs sends a UDP datagram to any port number that you specified. Using the IP SLAs Responder is optional for a UDP echo operation when using Cisco devices. The IP SLAs Responder cannot be configured on non-Cisco devices.

Q518. DRAG DROP 

Drag and drop each SNMP security model and level on the left to the corresponding mode of authentication on the right. 


Answer: 



Q519. Which two statements are true about VPLS? (Choose two.) 

A. It can work over any transport that can forward IP packets. 

B. It provides integrated mechanisms to maintain First Hop Resiliency Protocols such as HSRP, VRRP, or GLBP. 

C. It includes automatic detection of multihoming. 

D. It relies on flooding to propagate MAC address reachability information. 

E. It can carry a single VLAN per VPLS instance. 

Answer: D,E 

Explanation: 

VPLS relies on flooding to propagate MAC address reachability information. Therefore, flooding cannot be prevented. 

VPLS can carry a single VLAN per VPLS instance. To multiplex multiple VLANs on a single instance, VPLS uses IEEE QinQ.

Q520. Refer to the exhibit. 


What is the polling frequency set by this configuration? 

A. 60 seconds 

B. 10 seconds 

C. 360 seconds 

D. 60 milliseconds 

E. 10 milliseconds 

Answer: A 

Explanation: 

The frequency value lists the polling interval, in seconds.
