Question ID 17400 | Dig Server1.example.com, Resolve to successfully through DNS Where DNS server |
Option A | Answer : #vi /etc/resolv.conf nameserver 172.24.254.254 # dig server1.example.com #host server1.example.com DNS is the Domain Name System, which maintains a database that can help your computer translate domain names such as www.redhat.com to IP addresses such as 216.148.218.197. As no individual DNS server is large enough to keep a database for the entire Internet, they can refer requests to other DNS servers. DNS is based on the named daemon, which is built on the BIND (Berkeley Internet Name Domain) package developed through the Internet Software Consortium Users wants to access by name so DNS will interpret the name into ip address. You need to specify the Address if DNS server in each and every client machine. In Redhat Enterprise Linux, you need to specify the DNS server into /etc/resolv.conf file. After Specifying the DNS server address, you can verify using host, dig and nslookup commands. |

Question ID 17401 | One Logical Volume named lv1 is created under vg0. The Initial Size of that Logical |
Option A | Answer : The LVM system organizes hard disks into Logical Volume (LV) groups. Essentially, physical hard disk partitions (or possibly RAID arrays) are set up in a bunch of equal-sized chunks known as Physical Extents (PE). As there are several other concepts Physical Volume (PV) is the standard partition that you add to the LVM mix. Normally, a physical volume is a standard primary or logical partition. It can also be a RAID array. Physical Extent (PE) is a chunk of disk space. Every PV is divided into a number of equal sized PEs. Every PE in a LV group is the same size. Different LV groups can have different sized PEs. Logical Extent (LE) is also a chunk of disk space. Every LE is mapped to a specific PE. Logical Volume (LV) is composed of a group of LEs. You can mount a filesystem such as /home and /var on an LV. Volume Group (VG) is composed of a group of LVs. It is the organizational group for LVM. Most of the commands that you'll use apply to a specific VG. lvdisplay /dev/vg0/lv1 df h or df h mounted directory name lvextend L+400M /dev/vg0/lv1 4. resize2fs /dev/vg0/lv1 to bring extended size online. 5. Again Verify using lvdisplay and df h command. |
