Why did Branch1 router lose WAN connectivity with R1 router?. The IP address is misconfigured on PPP multilink interface on the Branch1 router. The PPP multilink group is misconfigured on the £ranch1 serial interfaces. The PPP multilink group is misconfigured on the R1 serial interfaces. The Branch1 serial interfaces are placed in a shutdown condition.

Where does routing occur within the DoD TCP/IP reference model?. application. internet. network. transport.

What value is primarily used to determine which port becomes the root port on each nonroot switch in a spanning-tree topology?. path cost. lowest port MAC address. VTP revision number. highest port priority number. port priority number and MAC address.

What is the danger of the permit any entry in a NAT access list?. It can lead to overloaded resources on the router. It can cause too many addresses to be assigned to the same interface. It can disable the overload command. It prevents the correct translation of IP addresses on the inside network.

Which three statements accurately describe Layer 2 Ethernet switches? (Choose three.). Spanning Tree Protocol allows switches to automatically share VLAN information. Establishing VLANs increases the number of broadcast domains. Switches that are configured with VLANs make forwarding decisions based on both Layer 2 and Layer 3 address information. Microsegmentation decreases the number of collisions on the network. In a properly functioning network with redundant switched paths, each switched segment will contain one root bridge with all its ports in the forwarding state. All other switches in that broadcast domain will have only one root port. If a switch receives a frame for an unknown destination, it uses ARP to resolve the address.

Which two features can you enable on a switch to capture and analyze frames that transit an interface? (Choose two). SNMP. SPAN. NetFlow. RSPAN. IP SLA.

Which two statements about EUI-64 addressing are true? (Choose two). A 64-bit interface identifier is derived from the interface MAC address. A 96-bit interface identifier is derived from the interface MAC address. A locally administered address has the universal/local bit set to 0. The address includes the hex digits FFFE after the first 24 bits of the interface MAC address. The address includes the hex digits FFFE after the last 24 bits of the interface MAC address.

There is a Layer 2 issue; an encapsulation mismatch on serial links. There is an OSPF hello and dead interval mismatch. The R3 router ID is configured on R4.

A new subnet with 60 hosts has been added to the network. Which subnet address should this network use to provide enough usable addresses while wasting the fewest addresses?. 192.168.1.56/26. 192.168.1.56/27. 192.168.1.64/26. 192.168.1.64/27.

A default gateway must be configured for the source and destination devices. The destination device must supporWhich command should you enter to configure a device as an NTP server?t the echo protocol.

Scenario: Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links. You are required to troubleshoot and resolve OSPF neighbor adjacency issues between the main office and the routers located in the remote branch offices. Question: An OSPF neighbor adjacency is not formed between R3 in the main office and R6 in the Branch3 office. What is causing the problem?. There is an area ID mismatch. There is a PPP authentication issue; the username is not configured on R3 and R6. There is an OSPF hello and dead interval mismatch. The R3 router ID is configured on R6.

What parameter can be different on ports within an EtherChannel?. speed. DTP negotiation settings. trunk encapsulation. duplex.

You are implementing ElGRP between the main office and branch offices. In Phase 1 you must implement and verify EIGRP configurations as mentioned in the topology in Phase 2. your colleague is expected to do NAT and ISP configurations 222 of 634 Cisco - 200-125 Identity the issues that you are encountering during Phase 1 EIGRP implementation. • Router R1 connects the main office to the Internet and routers R2 and R3 are internal routers • Routers Branch 1 and Branch2 connect to router R2 in the main office. • Users from the Branch1 LAN network 10 20 40 0724 are expected to perform testing of the application that is hosted on the servers in Server farm1, before servers are available for production - The GRE tunnel is configured between R3 and Branch1, and traffic between server farm1 and Branch1 LAN network 10 20 40 0/24 is routed through the GRE tunnel using static routes • The link between Branch1 and Branch2 is used as a secondary path in the event of failure of the primary path to mam office You have console access on R1. R2. R3. Branch1, and Branch2 devices Use only show commands to troubleshoot the issues Question: The traffic from Branch2 to the main office is using the secondary path instead of the primary path connected to R2. Which cause of the issue is true?. The network 192.163.11,0/30 was not advertised into EIGRP on Branch2. The IP address was misconfigured between the Branch2 and R2 interfaces. EIGRP packets were blocked by the inbound ACL on Branch2. The primary path has more link delay configured then secondary path which causes EIGRP to choose the secondary path.

Which two statements about configuring an EtherChannel on a Cisco switch are true? (Choose two.). The interfaces configured in the EtherChannel must be on the same physical switch. The interfaces configured in the EtherChannel must operate at the same speed and duplex mode. An EtherChannel can operate in Layer 2 mode only. The interfaces configured in the EtherChannel must be part of the same VLAN or trunk. The interfaces configured in the EtherChannel must have the same STP port path cost.

An administrator is trying to ping and telnet from SwitchC to RouterC with the results shown below. Correctly assign an IP address to interface fa0/1.

Remove access-group 102 out from interface s0/0/0 and add access-group 114 in. Remove access-group 106 in from interface fa0/0 and add access-group 104 in.

Scenario: Refer to the topology. Your company has decided to connect the main office with three other remote branch offices using point-to-point serial links.

Given the output shown from this Cisco Catalyst 2950, what is the reason that interface FastEthernet 0/10 is not the root port for VLAN 2?. This switch has more than one interface connected to the root network segment in VLAN 2. This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree. This switch interface has a higher path cost to the root bridge than another in the topology. This switch has a lower bridge ID for VLAN 2 than the elected designated switch.

Which three statements about Syslog utilization are true? (Choose three.). Utilizing Syslog improves network performance. The Syslog server automatically notifies the network administrator of network problems. A Syslog server provides the storage space necessary to store log files without using router disk space. There are more Syslog messages available within Cisco IOS than there are comparable SNMP trap messages. Enabling Syslog on a router automatically enables NTP for accurate time stamping. A Syslog server helps in aggregation of logs and alerts.

Which three statements about HSRP operation are true? (Choose three.). The virtual IP address and virtual MA+K44C address are active on the HSRP Master router. The HSRP default timers are a 3 second hello interval and a 10 second dead interval. HSRP supports only clear-text authentication. The HSRP virtual IP address must be on a different subnet than the routers' interfaces on the same LAN. The HSRP virtual IP address must be the same as one of the router's interface addresses on the LAN. HSRP supports up to 255 groups per interface, enabling an administrative form of load balancing.
