Which type of IPv6 static route is configured in the exhibit? fully specified static route floating static route recursive static route directly attached static route 4/20 While analyzing log files, a network administrator notices reoccurring native VLAN mismatches. What is the effect of these reoccurring errors? The control and management traffic on the error-occurring trunk port is being misdirected or dropped. Unexpected traffic on the error-occurring trunk port is being received. All traffic on the error-occurring trunk port is being switched correctly regardless of the error. All traffic on the error-occurring trunk port is being misdirected or dropped. 5/20 The computers used by the network administrators for a school are on the 10.7.0.0/27 network. Which two commands are needed at a minimum to apply an ACL that will ensure that only devices that are used by the network administrators will be allowed Telnet access to the routers? (Choose two.) Hint: 2 choices access-list standard VTYpermit 10.7.0.0 0.0.0.127 ip access-group 5 out access-class 5 in ip access-group 5 in access-list 5 permit 10.7.0.0 0.0.0.31 access-list 5 deny any 6/20 Which two characteristics describe the native VLAN? (Choose two.) Hint: 2 choices The native VLAN provides a common identifier to both ends of a trunk. Designed to carry traffic that is generated by users, this type of VLAN is also known as the default VLAN. The native VLAN traffic will be untagged across the trunk link. High priority traffic, such as voice traffic, uses the native VLAN. This VLAN is necessary for remote management of a switch. 7/20 A new network policy requires an ACL to deny HTTP access from all guests to a web server at the main office. All guests use addressing from the IPv6 subnet 2001:DB8:19:C::/64. The web server is configured with the address 2001:DB8:19:A::105/64. Implementing the NoWeb ACL on the interface for the guest LAN requires which three commands? (Choose two.) Hint: 3 choices deny ipv6 any any permit ipv6 any any deny tcp host 2001:DB8:19:A::105 any eq 80 deny tcp any host 2001:DB8:19:A::105 eq 80 ipv6 traffic-filter NoWeb in permit tcp any host 2001:DB8:19:A::105 eq 80 ip access-group NoWeb in 8/20 The buffers for packet processing and the running configuration file are temporarily stored in which type of router memory? RAM Flash NVRAM ROM 9/20 Refer to the exhibit. If the switch reboots and all routers have to re-establish OSPF adjacencies, which routers will become the new DR and BDR? Router R3 will become the DR and router R1 will become the BDR. Router R1 will become the DR and router R2 will become the BDR. Router R1 will become theB DR and router R2 will become the DR. Router R4 will become the DR and router R3 will become the BDR. 10/20 A network technician is configuring port security on switches. The interfaces on the switches are configured in such a way that when a violation occurs, packets with unknown source address are dropped and no notification is sent. Which violation mode is configured on the interfaces? shutdown restrict protect off 11/20 Refer to the exhibit. The Branch Router has an OSPF neighbor relationship with the HQ router over the 198.51.0.4/30 network. The 198.51.0.8/30 network link should serve as a backup when the OSPF link goes down. The floating static route command ip route 0.0.0.0 0.0.0.0 S0/1/1 100 was issued on Branch and now traffic is using the backup link even when the OSPF link is up and functioning. Which change should be made to the static route command so that traffic will only use the OSPF link when it is up? Add the next hop neighbor address of 198.51.0.8 Change the administrative distance to 120. Change the administrative distance to 1. Change the destination network to 198.51.0.5. 12/20 Fill in the blank.The default administrative distance for a static route is ____ Type answer. Hint: 1 character 13/20 Which three pairs of trunking modes will establish a functional trunk link between two Cisco switches? (Choose three.) Hint: 3 choices access – trunk dynamic desirable – dynamic desirable dynamic auto – dynamic auto access – dynamic auto dynamic desirable – trunk dynamic desirable – dynamic auto 14/20 The OSPF Type 1 packet is the _________ packet. Type answer. Hint: 5 characters 15/20 An OSPF router has three directly connected networks; 172.16.0.0/16, 172.16.1.0/16, and 172.16.2.0/16. Which OSPF network command would advertise only the 172.16.1.0 network to neighbors? router(config-router)# network 172.16.1.0 0.0.0.0 area 0 router(config-router)# network 172.16.1.0 0.0.255.255 area 0 router(config-router)# network 172.16.0.0 0.0.15.255 area 0 router(config-router)# network 172.16.1.0 255.255.255.0 area 0 16/20 Refer to the exhibit. An attacker on PC X sends a frame with two 802.1Q tags on it, one for VLAN 40 and another for VLAN 12. What will happen to this frame? SW-A will drop the frame because it is invalid. SW-A will leave both tags on the frame and send it to SW-B, which will forward it to hosts on VLAN 40. SW-A will remove the outer tag and send the rest of the frame across the trunk link, where SW-B will forward the frame to hosts on VLAN 12. SW-A will remove both tags and forward the rest of the frame across the trunk link, where SW-B will forward the frame to hosts on VLAN 40. 17/20 A standard ACL has been configured on a router to allow only clients from the 10.11.110.0/24 network to telnet or to ssh to the VTY lines of the router. Which command will correctly apply this ACL? access-list 11 in access-group 11 in access-list 110 in access-class 11 in 18/20 What are two ways of turning off DTP on a trunk link between switches? (Choose two.) Hint: 2 choices Change the native VLAN on both ports. Place the two attached switch ports in access mode. Configure attached switch ports with the dynamic desirable command option. Configure one port with the dynamic auto command option and the opposite attached switch port with the dynamic desirable command option. Configure attached switch ports with the nonegotiate command option. 19/20 Which statement is true about the difference between OSPFv2 and OSPFv3? OSPFv3 routers do not need to elect a DR on multiaccess segments. OSPFv3 routers do not need to have matching subnets to form neighbor adjacencies. OSPFv3 routers use a 128 bit router ID instead of a 32 bit ID. OSPFv3 routers use a different metric than OSPFv2 routers use. 20/20 What is the purpose of an access list that is created as part of configuring IP address translation? The access list defines the private IP addresses that are to be translated. The access list prevents external devices from being a part of the address translation. The access list defines the valid public addresses for the NAT or PAT pool. The access list permits or denies specific addresses from entering the device doing the translation.
