What is one difference between using Telnet or SSH to connect to a network device for management purposes? Telnet does not provide authentication whereas SSH provides authentication. Telnet sends a username and password in plain text, whereas SSH encrypts the username and password. Explanation: SSH provides security for remote management connections to a network device. SSH does so through encryption for session authentication username and password as well as for data transmission.

Telnet sends a username and password in plain text, which can be targeted to obtain the username and password through data capture. The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections. How should the network administrator change the displayed configuration to satisfy the requirement? Configure SSH on a different line. Modify the transport input command. What is the effect of using the switchport port-security command? All active switch ports should be manually secured using the switchport port-security command, which allows the administrator to control the number of valid MAC addresses allowed to access the port. This command does not specify what action will be taken if a violation occurs, nor does it change the process of populating the MAC address table. Where are dynamically learned MAC addresses stored when sticky learning is enabled with the switchport port-security mac-address sticky command?

The switches are new and have never been configured. Which three statements are correct about the final result of the connection? Choose three. The auto-MDIX feature will configure the interfaces eliminating the need for a crossover cable. The duplex capability has to be manually configured because it cannot be negotiated. If both switches support different speeds, they will each work at their own fastest speed. The link between switches will work as full-duplex. In this scenario, what will happen next? It processes more overhead than the controlled access methods do. It scales very well under heavy media use. It is a nondeterministic method. Collisions can decrease network performance. It is more complex than non-deterministic protocols.

The cyclic redundancy check CRC part of the trailer is used to determine if the frame has been modified during transit. Two types of cut-through switching methods are fast-forward and fragment-free. What is auto-MDIX? True or False? When a device is sending data to another device on a remote network, the Ethernet frame is sent to the MAC address of the default gateway. When data is destined for a remote network of any type, the data is sent to the default gateway device, the Layer 3 device that routes for the local network. The ARP table in a switch maps which two types of address together? These mappings can be learned by the switch dynamically through ARP or statically through manual configuration.

Refer to the exhibit. CCNA 1 v6. In this scenario, what will happen next? Explanation: When a network device wants to communicate with another device on the same network, it sends a broadcast ARP request. In this case, the request will contain the IP address of PC2. The ARP table for host A is shown. What happens when host A wants to send an IP packet to host D? Host A sends out the packet to the switch. The switch sends the packet only to the host D, which in turn responds. Every other host connected to the switch receives the broadcast and host D responds with its MAC address. All devices on the same network receive this broadcast. Host D will respond to this broadcast. Which network hosts will receive the ARP request sent by host A? The ARP broadcast would be sent to every device on the local network.

Explanation: One of the negative issues with ARP requests is that they are sent as a broadcast. This means all devices on the local link must receive and process the request. What are two potential network problems that can result from ARP operation? Choose two. On large networks with low bandwidth, multiple ARP broadcasts could cause data communication delays. Explanation: Large numbers of ARP broadcast messages could cause momentary data communications delays. ARP table overflows are very unlikely.

Multiple ARP replies resulting in the switch MAC address table containing entries that match the MAC addresses of connected nodes and are associated with the relevant switch port are required for normal switch frame forwarding operations. It is not an ARP caused network problem. Fill in the blank. A collision fragment, also known as a RUNT frame, is a frame of fewer than 64 bytes in length. Explain: A runt frame is a frame of fewer than 64 bytes, usually generated by a collision or a network interface failure.

On a Cisco switch, port-based memory buffering is used to buffer frames in queues linked to specific incoming and outgoing ports. Match the characteristic to the forwarding method. Not all options are used. A cut-through switch can forward frames before receiving the destination address field, thus presenting less latency than a store-and-forward switch. Because the frame can begin to be forwarded before it is completely received, the switch may transmit a corrupt or runt frame. All forwarding methods require a Layer 2 switch to forward broadcast frames. New Questions What is the minimum Ethernet frame size that will not be discarded by the receiver as a runt frame?

Because this type of attack involves multiple packets, an IPS sensor must maintain the state information. However, an IPS sensor cannot maintain the state information indefinitely. A composite signature is configured with a time period to maintain the state for the specific attack when it is first detected. Thus, an IPS may not be able to maintain all the information related to an attack such as total number of packets, total length of attack time, and the amount of bandwidth consumed by the attack. What is the effect? Alert messages are sent in syslog format. Alert messages are sent in trace file format. Alert messages are sent in event log format. The ip ips notify command is used to set the IPS event notification. This command has two options, log and sdee. The log option is to specify that notifications are sent in syslog format. The sdee option is to specify that notifications are sent in SDEE format.

If no option is specified, by default, notifications are sent in syslog format. The content of the file is signed by a Cisco private key to guarantee its authenticity and integrity. Network-based IPS should not be used with multiple operating systems. Network-based IPS does not detect lower level network events. Network-based IPS is less cost-effective. Network-based IPS cannot examine encrypted traffic. Network-based IPS devices are implemented as inline mode to actively monitor the traffic on networks. They can take immediate actions when security criteria match. True or False? A Cisco IDS does not affect the flow of traffic when it operates in promiscuous mode. What is a disadvantage of a pattern-based detection mechanism?

The normal network traffic pattern must be profiled first. It is difficult to deploy in a large network. It cannot detect unknown attacks. Its configuration is complex. The signatures must be created first. Hence this type of intrusion detection cannot detect unknown attacks. It is easy to configure and to deploy. Its operation does not depend on the information of normal network behavior or baseline. A security specialist configures an IPS so that it will generate an alert when an attack is first detected.

Alerts for the subsequent detection of the same attack are suppressed for a pre-defined period of time. Another alert will be generated at the end of the period indicating the number of the attack detected. Which IPS alert monitoring mechanism is configured? IPS solutions incorporate two types of alerts, atomic alerts and summary alerts. Atomic alerts are generated every time a signature triggers. A summary alert is a single alert that indicates multiple occurrences of the same signature from the same source address or port. With a summary alter, the first detection of the attack triggers a normal alert. Subsequent detection of the same attack is counted until the end of the signature summary interval.

When the length of time specified by the summary interval has elapsed, a summary alarm is sent, indicating the number of alarms that occurred during the time interval. What are two disadvantages of using an IDS? Choose two. The IDS does not stop malicious traffic. The IDS works offline using copies of network traffic. The IDS has no impact on traffic. The IDS analyzes actual forwarded packets. The IDS requires other devices to respond to attacks. The disadvantage of operating with mirrored traffic is that the IDS cannot stop malicious single-packet attacks from reaching the target before responding to the attack.
