NEW QUESTION 91
Refer to the exhibit.
Which two actions restrict access to router R1 by SSH? (Choose two.)
- A. Configure transport output ssh on line vty and remove sequence 20 from access list 100.
- B. Remove sequence 10 from access list 100 and add sequence 20 deny tcp any any eq telnet to access list 199
- C. Configure transport output ssh on line vty and remove sequence 10 from access list 199.
- D. Remove class-map ANY from service-policy CoPP
- E. Configure transport input ssh on line vty and remove sequence 30 from access list 100.
Answer: A,E
Explanation:
To only allow SSH to R1, we have to: + Deny Telnet in ACL 100 because the action of class-map: PERMIT is "permit" + Permit Telnet in ACL 199 because the action of class-map: ANY is "drop" But:
+ In ACL 100 there is a permit statement for Telnet traffic "20 permit tcp any any eq telnet (5 matches)" which is not correct so we must remove this statement. + In ACL 199 there is an ACL statement "10 deny tcp any eq telnet any (50 matches)". This statement is aimed for Telnet traffic leaving R1 which is not correct so we must remove this statement.
Note: + The command "transport output telnet ssh" allows telnet and SSH from this device (to other devices). + Telnet is TCP port 23. + When using Telnet on source port, it affects Telnet traffic leaving from R1.

Refer to the exhibit.
R2 is a route reflector, and R1 and R3 are route reflector clients. The route reflector learns the route to 172.16.25.0/24 from R1, but it does not advertise to R3. What is the reason the route is not advertised?
- A. R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.
- B. In route reflector setup, only classful prefixes are advertised to other clients.
- C. In route reflector setups, prefixes are not advertised from one client to another.
- D. Route reflector setup requires full IBGP mesh between the routers.

NEW QUESTION 97
Exhibit:
BGP is flapping after the Copp policy is applied. What are the two solutions to fix the issue?
(Choose two)
- A. Configure IP CEF to CoPP policy and BGP to work
- B. Configure a higher value for CIR under the class COPP-CRITICAL-7600
- C. Configure a three-color policer instead of two-color policer under class COPP-CRITICAL-7600
- D. Configure BGP in the COPP-CRITICAL-7600 ACL
- E. Configure a higher value for CIR under the default class to allow more packets during peak traffic
Answer: D,E
Explanation:
The policy-map COPP-7600 only rate-limit HTTP & HTTPS traffic (based on the ACL conditions) so any BGP packets will be processed in the class "class-default", which drops exceeded BGP packets. Therefore we have two ways to solve this problem:
+ Add BGP to the ACL with the statement "permit tcp any any eq bgp"
+ Configure higher value for CIR in default class as 2Mbps is too low for web traffic (http & https)

NEW QUESTION 109
Drag and drop the OSPF adjacency states from the left onto the correct descriptions on the right.
Answer:
Explanation:
Explanation
DownThis is the first OSPF neighbor state. It means that no information (hellos) has been received from this neighbor, but hello packets can still be sent to the neighbor in this state.
During the fully adjacent neighbor state, if a router doesn't receive hello packet from a neighbor within the Router Dead Interval time (RouterDeadInterval = 4*HelloInterval by default) or if the manually configured neighbor is being removed from the configuration, then the neighbor state changes from Full to Down.
AttemptThis state is only valid for manually configured neighbors in an NBMA environment. In Attempt state, the router sends unicast hello packets every poll interval to the neighbor, from which hellos have not been received within the dead interval.
InitThis state specifies that the router has received a hello packet from its neighbor, but the receiving router's ID was not included in the hello packet. When a router receives a hello packet from a neighbor, it should list the sender's router ID in its hello packet as an acknowledgment that it received a valid hello packet.
2-WayThis state designates that bi-directional communication has been established between two routers.
Bi-directional means that each router has seen the other's hello packet. This state is attained when the router receiving the hello packet sees its own Router ID within the received hello packet's neighbor field. At this state, a router decides whether to become adjacent with this neighbor. On broadcast media and non-broadcast multiaccess networks, a router becomes full only with the designated router (DR) and the backup designated router (BDR); it stays in the 2-way state with all other neighbors. On Point-to-point and Point-to-multipoint networks, a router becomes full with all connected routers.
At the end of this stage, the DR and BDR for broadcast and non-broadcast multiacess networks are elected.
For more information on the DR election process, refer to DR Election.
Note: Receiving a Database Descriptor (DBD) packet from a neighbor in the init state will also a cause a transition to 2-way state.
ExstartOnce the DR and BDR are elected, the actual process of exchanging link state information can start between the routers and their DR and BDR. (ie. Shared or NBMA networks).
In this state, the routers and their DR and BDR establish a master-slave relationship and choose the initial sequence number for adjacency formation. The router with the higher router ID becomes the master and starts the exchange, and as such, is the only router that can increment the sequence number. Note that one would logically conclude that the DR/BDR with the highest router ID will become the master during this process of master-slave relation. Remember that the DR/BDR election might be purely by virtue of a higher priority configured on the router instead of highest router ID. Thus, it is possible that a DR plays the role of slave. And also note that master/slave election is on a per-neighbor basis.
ExchangeIn the exchange state, OSPF routers exchange database descriptor (DBD) packets. Database descriptors contain link-state advertisement (LSA) headers only and describe the contents of the entire link-state database. Each DBD packet has a sequence number which can be incremented only by master which is explicitly acknowledged by slave. Routers also send link-state request packets and link-state update packets (which contain the entire LSA) in this state. The contents of the DBD received are compared to the information contained in the routers link-state database to check if new or more current link-state information is available with the neighbor.
LoadingIn this state, the actual exchange of link state information occurs. Based on the information provided by the DBDs, routers send link-state request packets. The neighbor then provides the requested link-state information in link-state update packets. During the adjacency, if a router receives an outdated or missing LSA, it requests that LSA by sending a link-state request packet. All link-state update packets are acknowledged.
FullIn this state, routers are fully adjacent with each other. All the router and network LSAs are exchanged and the routers' databases are fully synchronized.
Full is the normal state for an OSPF router. If a router is stuck in another state, it is an indication that there are problems in forming adjacencies. The only exception to this is the 2-way state, which is normal in a broadcast network. Routers achieve the FULL state with their DR and BDR in NBMA/broadcast media and FULL state with every neighbor in the remaining media such as point-to-point and point-to-multipoint.
Note: The DR and BDR that achieve FULL state with every router on the segment will display FULL/DROTHER when you enter the show ip ospf neighbor command on either a DR or BDR. This simply means that the neighbor is not a DR or BDR, but since the router on which the command was entered is either a DR or BDR, this shows the neighbor as FULL/DROTHER.

Refer to the exhibit.
A network administrator is using the DNA Assurance Dashboard panel to troubleshoot an OSPF adjacency that failed between Edge_NYC interface GigabitEthernet1/3 with Neighbor Edge_SNJ. The administrator observes that the neighborship is stuck in exstart state. How does the administrator fix this issue?
- A. Configure to match the OSPF interface speed and duplex settings on both routers.
- B. Configure to match the OSPF interface unique IP address and subnet mask on both routers.
- C. Configure to match the OSPF interface MTU settings on both routers.
- D. Configure to match the OSPF interface network types on both routers.
Answer: C
Explanation:
https://www.cisco.com/c/en/us/support/docs/ip/open-shortest-path-first-ospf/13684-12.html After two OSPF neighboring routers establish bi-directional communication and complete DR/BDR election (on multi-access networks), the routers transition to the exstart state. In this state, the neighboring routers establish a master/slave relationship and determine the initial database descriptor (DBD) sequence number to use while exchanging DBD packets.
Neighbors Stuck in Exstart/Exchange State The problem occurs most frequently when attempting to run OSPF between a Cisco router and another vendor's router. The problem occurs when the maximum transmission unit (MTU) settings for neighboring router interfaces don't match. If the router with the higher MTU sends a packet larger that the MTU set on the neighboring router, the neighboring router ignores the packet.
