NEW QUESTION 4
Which security zone is automatically defined by the system?
- A. The source zone
- B. The self zone
- C. The destination zone
- D. The inside zone
A zone is a logical area where devices with similar trust levels reside. For example, we could define a DMZ for devices in the DMZ in an organization. A zone is created by the administrator, and then interfaces can be assigned to zones. A zone can have one or more interfaces assigned to it. Any given interface can belong to only a single zone. There is a default zone, called the self zone, which is a logical zone.

- B. Malware is software used by nation states to commit cyber crimes.
- C. Malware is a collection of worms, viruses, and Trojan horses that is distributed as a single package.
- D. Malware is tools and applications that remove unwanted programs.
Malware, short for malicious software, is any software used to disrupt computer or mobile operations, gather sensitive information, gain access to private computer systems, or display unwanted advertising. Before the term malware was coined by Yisrael Radai in 1990, malicious software was referred to as computer viruses.
NEW QUESTION 12
What command could you implement in the firewall to conceal internal IP address?
- A. no source-route
- B. no cdp run
- C. no broadcast…
- D. no proxy-arp
The Cisco IOS software uses proxy ARP (as defined in RFC 1027) to help hosts with no knowledge of routing determine the media addresses of hosts on other networks or subnets. For example, if the router receives an ARP request for a host that is not on the same interface as the ARP request sender, and if the router has all of its routes to that host through other interfaces, then it generates a proxy ARP reply packet giving its own local data-link address. The host that sent the ARP request then sends its packets to the router, which forwards them to the intended host. Proxy ARP is enabled by default.
Router(config-if)# ip proxy-arp - Enables proxy ARP on the interface.
NEW QUESTION 13
What technology can you use to provide data confidentiality, data integrity and data origin authentication on your network?
- A. Certificate Authority
- B. IKE
- C. IPSec
- D. Data Encryption Standards
NEW QUESTION 14
Which technology can you implement to centrally mitigate potential threats when users on your network download files that might be malicious?
- A. Enable file-reputation services to inspect all files that traverse the company network and block files with low reputation scores.
- B. Verify that the company IPS blocks all known malicious websites.
- C. Verify that antivirus software is installed and up to date for all users on your network.
- D. Implement URL filtering on the perimeter firewall.
NEW QUESTION 15
Which three ESP fields can be encrypted during transmission? (Choose three.)
- A. Security Parameter Index
- B. Sequence Number
- C. MAC Address
- D. Padding
- E. Pad Length
- F. Next Header
The packet begins with two 4-byte fields (Security Parameters Index (SPI) and Sequence Number). Following these fields is the Payload Data, which has substructure that depends on the choice of encryption algorithm and mode, and on the use of TFC padding, which is examined in more detail later. Following the Payload Data are Padding and Pad Length fields, and the Next Header field. The optional Integrity Check Value (ICV) field completes the packet.
NEW QUESTION 16
Which IPS mode is less secure than other options but allows optimal network throughput?
- A. Promiscuous mode
- B. inline mode
- C. transparent mode
- D. inline-bypass mode
The recommended IPS deployment mode depends on the goals and policies of the enterprise. IPS inline mode is more secure because of its ability to stop malicious traffic in real-time, however it may impact traffic throughput if not properly designed or sized. Conversely, IPS promiscuous mode has less impact on traffic
throughput but is less secure because there may be a delay in reacting to the malicious traffic. https://www.cisco.com/c/en/us/td/docs/solutions/Enterprise/Security/SAFE_RG/safesmallentnetworks.html
NEW QUESTION 17
In which two situations should you use out-of-band management? (Choose two.)
- A. when a network device fails to forward packets
- B. when you require ROMMON access
- C. when management applications need concurrent access to the device
- D. when you require administrator access from multiple locations
- E. when the control plane fails to respond
OOB management is used for devices at the headquarters and is accomplished by connecting dedicated management ports or spare Ethernet ports on devices directly to the dedicated OOB management network hosting the management and monitoring applications and services. The OOB management network can be either implemented as a collection of dedicated hardware or based on VLAN isolation.
NEW QUESTION 18

NEW QUESTION 20
Which option is a characteristic of the RADIUS protocol?
- A. uses TCP
- B. offers multiprotocol support
- C. combines authentication and authorization in one process
- D. supports bi-directional challenge
http://www.cisco.com/en/US/tech/tk59/technologies_tech_note09186a0080094e99.shtml Authentication and Authorization
RADIUS combines authentication and authorization. The access-accept packets sent by the RADIUS server to the client contain authorization information. This makes it difficult to decouple authentication and authorization.
TACACS+ uses the AAA architecture, which separates AAA. This allows separate authentication solutions that can still use TACACS+ for authorization and accounting. For example, with TACACS+, it is possible to use Kerberos authentication and TACACS+ authorization and accounting. After a NAS authenticates on a Kerberos server, it requests authorization information from a TACACS+ server without having to
NAS informs the TACACS+ server that it has successfully authenticated on a Kerberos server, and the server then provides authorization information.
During a session, if additional authorization checking is needed, the access server checks with a TACACS+ server to determine if the user is granted permission to use a particular command. This provides greater control over the commands that can be executed on the access server while decoupling from the authentication mechanism.
NEW QUESTION 21
Which two commands are used to implement Cisco IOS Resilient Configuration? (Choose two.)
- A. secure boot-image
- B. copy running-config startup-config
- C. secure boot-config
- D. copy flash:/ios.bin tftp
- E. copy running-config tftp
The Cisco IOS Resilient Configuration feature enables a router to secure and maintain a working copy of the running image and configuration so that those files can withstand malicious attempts to erase the contents of persistent storage (NVRAM and flash).
In 12.3(8)T this feature was introduced.
The following commands were introduced or modified: secure boot-config, secure boot-image, showsecure bootset.
NEW QUESTION 22
Which IPSec mode is used to encrypt traffic directly between a client and a server VPN endpoint?
- A. transport mode
- B. tunnel mode
- C. quick mode
- D. aggressive mode
NEW QUESTION 23
What is the only permitted operation for processing multicast traffic on zone-based firewalls?
- A. Only control plane policing can protect the control plane against multicast traffic.
- B. Stateful inspection of multicast traffic is supported only for the self-zone.
- C. Stateful inspection for multicast traffic is supported only between the self-zone and the internal zone.
- D. Stateful inspection of multicast traffic is supported only for the internal zone.
Neither Cisco IOS ZFW or Classic Firewall include stateful inspection support for multicast traffic. So the only choice is A.

NEW QUESTION 26
Which two NAT types allows only objects or groups to reference an IP address? (choose two)
- A. dynamic NAT
- B. dynamic PAT
- C. static NAT
- D. identity NAT
Adding Network Objects for Mapped Addresses
For dynamic NAT, you must use an object or group for the mapped addresses. Other NAT types have the option of using inline addresses, or you can create an object or group according to this section.
* Dynamic NAT:
+ You cannot use an inline address; you must configure a network object or group.
+ The object or group cannot contain a subnet; the object must define a range; the group can include hosts and ranges.
+ If a mapped network object contains both ranges and host IP addresses, then the ranges are used for dynamic NAT, and then the host IP addresses are used as a PAT fallback.
* Dynamic PAT (Hide):
+ Instead of using an object, you can optionally configure an inline host address or specify the interface address.
+ If you use an object, the object or group cannot contain a subnet; the object must define a host, or for a PAT pool, a range; the group (for a PAT pool) can include hosts and ranges.
* Static NAT or Static NAT with port translation:
+ Instead of using an object, you can configure an inline address or specify the interface address (for static NAT-with-port-translation).
+ If you use an object, the object or group can contain a host, range, or subnet.
* Identity NAT
+ Instead of using an object, you can configure an inline address.
+ If you use an object, the object must match the real addresses you want to translate.
NEW QUESTION 27
