QUESTION 3 From which of the following attacks can Message Authentication Code (MAC) shield your network? A. DoS B. DDoS C. spoofing D. SYN floods Correct Answer: C Message Authentication Code (MAC) can shield your network from spoofing attacks. Spoofing, also known as masquerading, is a popular trick in which an attacker intercepts a network packet, replaces the source address of the packets header with the address of the authorized host, and reinserts fake information which is sent to the receiver. This type of attack involves modifying packet contents. MAC can prevent this type of attack and ensure data integrity by ensuring that no data has changed. MAC also protects against frequency analysis, sequence manipulation, and ciphertext-only attacks. MAC is a secure message digest that requires a secret key shared by the sender and receiver, making it impossible for sniffers to change both the data and the MAC as the receiver can detect the changes. A denial- of-service (DoS) attack floods the target system with unwanted requests, causing the loss of service to users. One form of this attack generates a flood of packets requesting a TCP connection with the target, tying up all resources and making the target unable to service other requests. MAC does not prevent DoS attacks. Stateful packet filtering is the most common defense against a DoS attack. A Distributed Denial of Service attack (DDoS) occurs when multiple systems are used to flood the network and tax the resources of the target system. Various intrusion detection systems, utilizing stateful packet filtering, can protect against DDoS attacks. In a SYN flood attack, the attacker floods the target with spoofed IP packets and causes it to either freeze or crash. A SYN flood attack is a type of denial of service attack that exploits the buffers of a device that accept incoming connections and therefore cannot be prevented by MAC. Common defenses against a SYN flood attack include filtering, reducing the SYN-RECEIVED timer, and implementing SYN cache or SYN cookies.

QUESTION 5 This topology contains 3 routers and 1 switch. Complete the topology. Drag the appropriate device icons to the labeled Device Drag the appropriate connections to the locations labeled Connections. 100-105 PDF Dumps | 100-105 Study Guide | 100-105 Braindumps 3 / 11https://www.lead4pass.com/100-105.html 2020 Latest lead4pass 100-105 PDF and VCE dumps Download Drag the appropriate IP addresses to the locations labeled IP address (Hint: use the given host addresses and Main router information) To remove a device or connection, drag it away from the topology. Use information gathered from the Main router to complete the configuration of any additional routers. No passwords are required to access the Main router. The config terminal command has been disabled for the HQ router. The router does not require any configuration.
Configure each additional router with the following: Configure the interfaces with the correct IP address and enable the interfaces. Set the password to allow console access to consolepw Set the password to allow telnet access to telnetpw Set the password to allow privilege mode access to privpw Not E: Because routes are not being added to the configurations, you will not be able to ping through the internetwork. All devices have cable autosensing capabilities disabled. All hosts are PC\\’s Correct Answer: Answer: Specify appropriate devices and drag them on the “Device” boxes For the device at the bottom-right box, we notice that it has 2 interfaces Fa0/2 and Fa0/4; moreover the link connects the PC on the right with the device on the bottom-right is a straight-through link -> it is a switch The question stated that this topology contains 3 routers and 1 switch -> two other devices are routers Place them on appropriate locations as following: (Host D and host E will be automatically added after placing two routers. Click on them to access neighboring routers) Specify appropriate connections between these devices: + The router on the left is connected with the Main router through FastEthernet interfaces: use a crossover cable + The router on the right is connected with the Main router through Serial interfaces: use a serial cable + The router on the right and the Switch: use a straight-through cable + The router on the left and the computer: use a crossover cable (To remember which type of cable you should use, follow these tips: -To connect two serial interfaces of 2 routers we use serial cable -To specify when we use crossover cable or straight-through cable, we should remember: Group 1: Router, Host, Server Group 2: Hub, Switch One device in group 1 + One device in group 2: use straight-through cable Two devices in the same group: use crossover cable For example, we use straight-through cable to connect switch to router, switch to host, hub to host, hub to server… and we use crossover cable to connect switch to switch, switch to hub, router to router, host to host.) Assign appropriate IP addresses for interfaces: From Main router, use show running-config command. (Notice that you may see different IP addresses in the real CCNA exam, the ones shown above are just used for demonstration) From the output we learned that the ip address of Fa0/0 interface of the Main router is 192.168.152.177/28. This address belongs to a subnetwork which has: Increment: 16 (/28 = 255.255.255.240 or 1111 1111.1111 1111.1111 1111.1111 0000) Network address: 192.168.152.176 (because 176 = 16 * 11 and 176 192.168.152.190 and assign it to the Fa0/0 interface the router on the left Use the same method for interface Serial0/0 with an ip address of 192.168.152.161 Increment: 16 Network address: 192.168.152.160 (because 160 = 16 * 10 and 160 and we choose 192.168.152.174 for Serial0/0 interface of the router on the right Interface Fa0/1 of the router on the left IP (of the computer on the left) : 192.168.152.129/28 Increment: 16 Network address: 192.168.152.128 (because 128 = 16 * 8 and 128 we choose 192.168.152.142 from the list Interface Fa0/0 of the router on the right IP (of the computer on the left) : 192.168.152.225/28 Increment: 16 Network address: 192.168.152.224 (because 224 = 16 * 14 and 224 we choose 192.168.152.238 from the list Let\\’s have a look at the picture below to summarize Configure two routers on the left and right with these commands: Router1 = router on the left Assign appropriate IP addresses to Fa0/0 100-105 PDF Dumps | 100-105 Study Guide | 100-105 Braindumps 5 / 11https://www.lead4pass.com/100-105.html 2020 Latest lead4pass 100-105 PDF and VCE dumps Download and Fa0/1 interfaces: Router1>enable Router1#configure terminal Router1(config)#interface fa0/0 Router1(config-if)#ip address 192.168.152.190 255.255.255.240 Router1(config-if)#no shutdown Router1(config-if)#interface fa0/1 Router1(config-if)#ip address 192.168.152.142 255.255.255.240 Router1(config-if)#no shutdown Set passwords (configure on two routers) + Console password: Router1(config-if)#exit Router1(config)#line console 0 Router1(config-line)#password consolepw Router1(config-line)#login Router1(config-line)#exit + Telnet password: Router1(config)#line vty 0 4 Router1(config-line)#password telnetpw Router1(config-line)#login Router1(config-line)#exit + Privilege mode password: Router1(config)#enable password privpw Save the configuration: Router1(config)#exit Router1#copy running-config startup-config Configure IP addresses of Router2 (router on the right) Router2>enable Router2#configure terminal Router2(config)#interface fa0/0 Router2(config-if)#ip address 192.168.152.238 255.255.255.240 Router2(config-if)#no shutdown Router2(config-if)#interface serial0/0 Router2(config-if)#ip address 192.168.152.174 255.255.255.240 Router2(config-if)#no shutdown Then set the console, telnet and privilege mode passwords for Router2 as we did for Router1, remember to save the configuration when you finished.

QUESTION 9 Which statements describe the routing protocol OSPF? (Choose three) A. It supports VLSM. B. It is used to route between autonomous systems. C. It confines network instability to one area of the network. D. It increases routing overhead on the network. E. It allows extensive control of routing updates. F. It is simpler to configure than RIP v2. Correct Answer: ACE The OSPF protocol is based on link-state technology, which is a departure from the Bellman-Ford vector based algorithms used in traditional Internet routing protocols such as RIP. OSPF has introduced new concepts such as authentication of routing updates, Variable Length Subnet Masks (VLSM), route summarization, and so forth. OSPF uses flooding to exchange link-state updates between routers. Any change in routing information is flooded to all routers in the network. Areas are introduced to put a boundary on the explosion of link-state updates. Flooding and calculation of the Dijkstra algorithm on a router is limited to changes within an area.

Box 1: memory-optimized table In-Memory OLTP can provide great performance benefits for transaction processing, data ingestion, and transient data scenarios. Box 2: materialized view To support efficient querying, a common solution is to generate, in advance, a view that materializes the data in a format suited to the required results set. The Materialized View pattern describes generating prepopulated views of data in environments where the source data isn\\’t in a suitable format for querying, where generating a suitable query is difficult, or where query performance is poor due to the nature of the data or the data store. These materialized views, which only contain data required by a query, allow applications to quickly obtain the information they need. In addition to joining tables or combining data entities, materialized views can include the current values of calculated columns or data items, the results of combining values or executing transformations on the data items, and values specified as part of the query. A materialized view can even be optimized for just a single query. References: https://docs.microsoft.com/en-us/azure/architecture/patterns/materialized-view

QUESTION 2 Which three benefits do VXLANs offer compared to VLANs (Choose three.) A. It provides a solution to extend Layer 2 segments over a shared Layer 3 routed network. B. It provides better utilization of available network paths in the underlying infrastructure. C. VXLAN uses a 16-bit VNIS to overcome the 4094 VLAN scale limitation. D. VXLAN uses a 24-bit VNID to overcome the 4094 VLAN scale limitation. E. It provides a solution to extend Layer 2 segments over a single Layer 2 VLAN. F. It provides better utilization of available network paths in the overlay infrastructure. Correct Answer: ABD VXLANOverview As its name indicates, VXLAN is designed to provide the same Ethernet Layer 2 network services as VLAN does today, but with greater extensibility and flexibility. Compared to VLAN, VXLAN offers the following benefits: Flexible placement of multitenant segments throughout the data center: It provides a solution to extend Layer 2 segments over the underlying shared network infrastructure so that tenant workload can be placed across physical pods in the data center. Higher scalability to address more Layer 2 segments: VLANs use a 12-bit VLAN ID to address Layer 2 segments, which results in limiting the scalability of only 4094 VLANs. VXLAN uses a 24-bit segment ID known as the VXLAN network identifier (VNID), which enables up to 16 million VXLAN segments to coexist in the same administrative domain. Better utilization of available network paths in the underlying infrastructure: VLAN uses the Spanning Tree Protocol for loop prevention, which ends up not using half of the network links in a network by blocking redundant paths. In contrast, VXLAN packets are transferred through the underlying network based on its Layer 3 header and can take complete advantage of Layer 3routing, equal-cost multipath (ECMP) routing, and link aggregation protocols to use all available paths. VXLAN Encapsulation and Packet Format VXLAN is a Layer 2 overlay scheme over a Layer 3 network. It uses MAC Address-in-User Datagram Protocol (MAC-in-UDP) encapsulation to provide a means to extend Layer 2 segments across the data center network. VXLAN is a solution to support a flexible, large-scale multitenant environment over a shared common physical infrastructure. The transport protocol over the physical data center network is IP plus UDP.

QUESTION 10 Which two statements about CFS are true? (Choose two.) A. CFS distributes the local NTP configuration to master only which then forwards to all devices in the network. B. After enabling CFS, a network-wide lock is applied to NTP whenever an NTP configuration is started and released once after the change has been committed or discarded. C. If CFS is used to distribute NTP, all devices in the network must have the different VRFs configured then as used for NTP. D. You must manually distribute NTP authentication keys on the NTP server and Cisco NX-OS devices across the network. E. CFS requires a license to be installed before it can be used to distribute NTP.
